JOURNAL OF ETHNOPHARMACOLOGY 2024; 335:118603. [PMID: 39067832 DOI: 10.1016/j.jep.2024.118603] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/22/2024] [Revised: 07/14/2024] [Accepted: 07/19/2024] [Indexed: 07/30/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cordyceps militaris, a traditional medicinal fungus, parasitizes the intestines of lepidopteron pupae or larvae, predominantly during the winter, and undergoes fruiting in the summer or autumn. Compounds extracted from C. militaris have demonstrated a broad spectrum of pharmacological effects, including antioxidant, anti-tumor, anti-metastatic, anti-inflammatory, antiviral, anti-diabetic, and various others. AIM OF THE STUDY Herein, our study aimed at elucidating the acute, sub-acute toxicity, and genotoxicity profiles of C. militaris methanolic extract following oral administration in Swiss albino mice, representing the inaugural comprehensive exploration of the toxicological and safety profiles of C. militaris. MATERIALS AND METHODS Prior studies have predominantly focused on its biological activities rather than its toxicity. Acute oral toxicity study was conducted at 500, 1000, and 2000 mg/Kg B.W. doses of C. militaris over a 14-day period. For sub-acute toxicity study, three groups of mice were administered 100, 300, and 600 mg/Kg B.W. of C. militaris extract for 28 consecutive days; one group served as a control. Mice were monitored for their body weight and behavioural changes once daily. Hematological, serum biochemical, histopathological, histomorphometric, seminal parameters, and mutagenic investigations were performed post-treatment period. RESULTS Acute oral toxicity study at 2000 mg/Kg revealed no signs of toxicity, with an LD50 value surpassing 2000 mg/Kg. No occurrences of mortality observed, and no significant changes were noted in body weight, organ weight, or behaviour. Hematological analysis illustrated a marked upsurge in RBC, Hb, HCT, PLT, MPV, and PCT, alongside minor variations in differential leucocyte count post 28-day treatment. Liver enzyme tests indicated slight elevation in ALP, while renal enzyme tests showed alterations in CRE and BUN levels. Genotoxicity profile and histopathological assessments of the liver, spleen, testis, and ovary manifested no remarkable irregularities, except for mild renal toxicity. Seminal parameters including sperm concentration, motility and testosterone levels demonstrated a noteworthy increase. CONCLUSIONS The study sheds light on the potential risks and safety considerations associated with C. militaris-based medicinal products. These findings establish a foundation for further investigations and the refinement of dosage optimization in the application of C. militaris, with the aim of mitigating any potential adverse effects.

The investigation on an ethnic medicinal plant of Elsholtiza bodinieri Vaniot: Chemical constituents, acute, 28-day subacute and 90-day subchronic toxicity evaluation. JOURNAL OF ETHNOPHARMACOLOGY 2024; 335:118635. [PMID: 39074518 DOI: 10.1016/j.jep.2024.118635] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/04/2024] [Revised: 07/25/2024] [Accepted: 07/26/2024] [Indexed: 07/31/2024]
Abstract
ETHNOPHARMACOLOGICAL SIGNIFICANCE Elsholtiza bodinieri Vaniot, belonging to the family Lamiaceae, has important medicinal value in Yunnan province of China. Traditionally, its aerial parts have been used as an ethnomedicine to treat diaphoresis, headache, fever, cough, pharyngitis, dyspepsia, and hepatitis. However, the safety assessment of E. bodinieri is still unexplored. AIM OF THE STUDY This study aimed to investigate the phytochemical constituents of the hot water extract from E. bodinieri (HEEB) and evaluate the 14-day acute, 28-day subacute and 90-day subchronic toxicity by oral administration in Sprague-Dawley (SD) rats. MATERIALS AND METHODS The chemical constituents of HEEB were analyzed by UHPLC-ESI-HRMS/MS. Firstly, SD rats were chosen for a single oral administration of the maximum dose of 5000 mg/kg to evaluate toxicity. Subsequently, consecutive 28-day subacute and 90-day subchronic toxicity assessments of HEEB were conducted on Sprague-Dawley (SD) rats through repeated doses of 2500, 1250, 625, and 312.5 mg/kg for the former, and 1500, 1000, and 500 mg/kg for the latter. For toxicity evaluation, hematology and serum biochemical indicators were determined, and major organs of the rats were collected to calculate organ coefficients. Additionally, hematoxylin-eosin (H&E) staining was performed on the collected tissues to assess histopathological changes induced by repeated oral administration of HEEB. RESULTS A total of 23 compounds were identified by UHPLC-ESI-HRMS/MS analysis. Acute toxicity assessment revealed that oral administration of HEEB did not induce mortality and unnormal behavior changes in female rats over a 14-day period, suggesting that the approximate lethal dose (ALD) was higher than 5000 mg/kg. In consecutive 28-day and 90-day toxicity evaluations, HEEB doses of 2500 mg/kg and 1500 mg/kg resulted in hepatic and kidney tissue damage in both female and male rats, which was verified by the increased levels of AST, ALT, BUN, Na+, and Cl-. CONCLUSIONS After the acute, 28-day subacute and 90-day subchronic toxicity evaluation, the No Observed Adverse Effect Level (NOAEL) was determined as 1000 mg/kg/day. These findings not only provided a safety information for its medicinal and edible application, but also promoted the further comprehensive development of this plant.

Sohn E, Kim YJ, Lim HS, Jeong SJ. Single acute and repeated subacute toxicity evaluations of Annona atemoya leaf extract with in vitro anti-inflammatory potential. Drug Chem Toxicol 2024:1-12. [PMID: 39360591 DOI: 10.1080/01480545.2024.2407866] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2024] [Revised: 08/26/2024] [Accepted: 09/18/2024] [Indexed: 10/04/2024]
Abstract
The nutraceutical and biological potential of Annona atemoya, a fruiting plant, has been reported. We and others have demonstrated that A. atemoya leaf extract (AAL) has various pharmacological properties, such as antioxidant, antimicrobial, and neuroprotective effects. However, knowledge about the safety and potential toxicity of AAL remains limited. We aimed to assess the potential toxicity of AAL using acute and repeated subacute oral toxicity tests in rats. In both acute and repeated subacute toxicity test, no AAL-related behavioral abnormalities or changes in mortality, food intake, body weight were observed up to a dosage of 2000 mg/kg, indicating that the median lethal dose of AAL is higher than 2000 mg/kg. In subacute toxicity tests, no significant changes in hematological and biochemical parameters, urinalysis results, and histopathological variables were observed. Therefore, the no-observed-adverse-effect level (NOAEL) of orally administered AAL was estimated to be 2000 mg/kg/day in male and female rats. We also examined the effect of AAL on the inflammatory reaction in lipopolysaccharide (LPS)-stimulated BV-2 cells. AAL treatment significantly inhibited the LPS-stimulated increases in the levels of nitric oxide (NO) and inflammatory cytokines, implying that AAL has an anti-inflammatory effect. Quality control analysis revealed that two marker compounds, rutin and isoquercitrin, were present at 27.570 and 4.322 mg/g, respectively, in a freeze-dried AAL sample and were completely eluted within 27 min. The extraction recovery was 99.47-103.80%, and the precision was ≤2.79%. Overall, these findings suggest the safety, anti-inflammatory activity, and standardization of AAL.

In vivo evaluation by oral administration of chitosan combined with bioactive glass against cadmium-induced toxicity in rats. Int J Biol Macromol 2024; 276:133845. [PMID: 39004258 DOI: 10.1016/j.ijbiomac.2024.133845] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2024] [Revised: 07/09/2024] [Accepted: 07/11/2024] [Indexed: 07/16/2024]
Abstract
Bioactive glass and chitosan are biomaterials widely used for orthopedic applications, notably as bone grafts. Although these biomaterials show promising therapeutic properties, no research has yet examined their potential for oral administration in soft tissue protection, particularly against metal toxicity. The aim of our study was to evaluate the potential of chitosan from cuttlefish (CHS) bone combined with bioactive glass (BG) against Cadmium-induced toxicity in rats. Cadmium (Cd), a heavy metal that accumulates in tissues, causes various disorders. Experiments were carried out on rats intoxicated acutely by oral administration of Cd (20 mg/kg body weight) and/or concomitantly with oral administration of CHS/BG (100 mg/kg body weight) for 7 days. Using pathophysiological and biochemical tests, we evaluated the detoxifying effect of orally administered CHS/BG against Cd toxicity. Our results showed, for the first time, a significant detoxifying effect of CHS/BG against Cd-induced toxicity in rats. Treatment with CHS/BG protected rats against the harmful effects of Cd by reducing lipid peroxidation levels and enhancing antioxidant enzyme activities. In addition, it helped restore phosphocalcic balance and protect liver, kidney and brain function. Remarkably, it also reduced Cd levels in the liver, kidneys and brain, as well as in the bones of rats. These results show that oral administration of CHS/BG has a strong therapeutic potential on tissues through detoxification of cadmium-exposed rats.

Safety assessment of enzymatically converted chicken bile as a novel food material: Genotoxicity, teratogenicity, and acute and subchronic toxicity studies. J Food Sci 2024; 89:5164-5178. [PMID: 38922919 DOI: 10.1111/1750-3841.17183] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2024] [Revised: 04/30/2024] [Accepted: 06/06/2024] [Indexed: 06/28/2024]
Abstract
Enzymatically converted chicken bile (CB), prepared by converting taurine deoxycholic acid (TCDCA) to taurine ursodeoxycholic acid (TUDCA) in CB, possesses various functional activities. But their nutrient composition and safety assessment have not been fully investigated yet. CB was mainly composed of proteins and steroids. CB did not show genotoxic effects based on Ames test, mammalian erythrocyte micronucleus test, and in vitro mammalian chromosomal aberration test. There were no growth abnormalities or deaths in the acute toxicity test for mice, indicating that CB is nontoxic with an LD50 > 10 g/kg·body weight (BW). Subchronic toxicity test and genotoxicity test were performed based on intake of 0.5 g CB per person daily at expanded doses of 33.3, 100, and 300 times (278, 833, and 2500 mg/kg·BW). The result indicated that CB at 833 mg/kg·BW showed no toxicity on BW, body weight gain, food intake, hematological, serum biochemistry, absolute/relative organ weights, urinalysis, and pathological features of rats in the subchronic toxicity test, while CB at 833 mg/kg·BW induced maternal toxicity with no fetus teratogenicity or embryotoxicity in the teratogenicity test. In conclusion, CB did not show toxic effects and a long-term daily intake of CB at 0.5 g per person is considered safe, but pregnant women should avoid it. These findings could provide a reference for the safe use of CB in functional food.

Abstract
The study aimed to evaluate the antithrombotic action of Acrocomia aculeata pulp oil (AAPO) in natura, in an in vitro experimental model. AAPO was obtained by solvent extraction, and its chemical characterization was performed by gas chromatography coupled to a mass spectrometer (GC-MS). In vitro toxicity was evaluated with the Trypan Blue exclusion test and in vivo by the Galleria mellonella model. ADP/epinephrine-induced platelet aggregation after treatment with AAPO (50, 100, 200, 400, and 800 μg/mL) was evaluated by turbidimetry, and coagulation was determined by prothrombin activity time (PT) and activated partial thromboplastin time (aPTT). Platelet activation was measured by expression of P-selectin on the platelet surface by flow cytometry and intraplatelet content of reactive oxygen species (ROS) by fluorimetry. The results showed that AAPO has as major components such as oleic acid, palmitic acid, lauric acid, caprylic acid, and squalene. AAPO showed no toxicity in vitro or in vivo. Platelet aggregation decreased against agonists using treatment with different concentrations of AAPO. Oil did not interfere in PT and aPTT. Moreover, it expressively decreased ROS-induced platelet activation and P-selectin expression. Therefore, AAPO showed antiplatelet action since it decreased platelet activation verified by the decrease in P-selectin expression as well as in ROS production.

Abstract
Ferroptosis as a promising method of cancer treatment heavily relies on the intracellular iron ion level. Herein, a new iron-supplement nanodrug was developed by conjugating transferrin-homing peptide T10 on the surface of cross-linked lipoic acid vesicles (T10@cLAV), which could hijack blood transferrin (Tf) and specifically deliver it to tumor cells to elevate the Fe2+ level. Meanwhile, the intracellular degradation product of cLAV, dihydrolipoic acid, could regenerate Fe2+ to further boost the ferroptosis. The results disclosed that T10@cLAV achieved tumor inhibition comparable to that of cisplatin at a dose as low as 5 mg/kg in the HeLa tumor-bearing nude mice model and caused no toxicity at the dose up to 300 mg/kg. This tactful iron-supplement strategy of hijacking blood Tf is superior to the current strategies: one is the induction of intracellular ferritin degradation, which is limited by the low content of ferritin, and the other is the delivery of iron-based materials, which easily causes adverse effects.

Abstract
Introduction: Acori Tatarinowii Rhizoma (ATR) is a well-known traditional Chinese medicine that is used for treating neuropathic diseases. However, there is little information about the safety of ATR. Methods: The present study evaluated the acute and subacute oral toxicity of a water extract of ATR in Institute of Cancer Research (ICR) mice. In acute trials, a single administration of extract at a dose 5,000 mg/kg body weight led to no clinical signs of toxicity or mortality, indicating that the lethal dose (LD50) exceeded 5,000 mg/kg. A subacute toxicity test was done using daily doses of 1,250, 2,500, and 5,000 mg/kg of the ATR extract for 28 days, which did not show any adverse clinical symptoms or mortality. However, the male renal organ index and urea level in mice given 5,000 mg/kg was obviously abnormal, which was consistent with pathological results and suggested that this dose might cause kidney injury. Results: Doses of ATR lower than 2,500 mg/kg could be regarded as safe, although the potential cumulative effects of long-term use of high doses of ATR need to be considered. Discussion: The study highlights the function of ATR in reducing blood lipids and provides a new idea for its widespread clinical use in the future.

Abstract
Nutritional supplements have been used to improve immune function. Condensed fuzheng extract (CFE) is a well-known traditional Chinese medicine (TCM) formula that is predominantly made from sheep placenta, Astragalus mongholicus Bunge, and Polygonatum kingianum Collett & Hemsl. However, the toxicological profile of CFE has not been determined. In this study, we investigated the acute (14 days) and sub-chronic (90 days) oral toxicities of CFE in mice and rats and the phytochemical composition of CFE. Materials and methods For the assessment of acute toxicity, 80 ICR mice of both sexes were randomly divided into four groups. Three groups were treated with 4500, 2250 and 1125 mg/kg/d bw CFE daily (n = 10/group per sex) for 14 days; a separate group was used as control. To test the sub-chronic toxicity, male and female Sprague Dawley rats were orally administered 8150, 4075 or 2037 mg/kg bw of CFE for 90 days; a control group was included. Hematological, biochemical, and histopathological markers were tested at the end of the experiment. The chemical composition of CFE was determined by UPLC-HRMS method. Results In both acute and sub-chronic toxicity studies, no mortalities, indications of abnormality, or treatment-related adverse effects were observed. The LD50 of CFE was higher than 4500 mg/kg. There were no significant changes in the hematological and biochemical data in the treatment group compared with the control group (p > 0.05). Histopathological analyses of the heart, liver, spleen, lungs, kidneys, thymus, testes (male rats) and ovaries (female rats) revealed no anatomical changes of each organ. Phytochemical analysis of CFE revealed the presence of flavonoids (highest abundance), phenols and alkaloids. In conclusion, our results showed that CFE is a safe and non-toxic formula. We also reported phytochemicals in CFE that may possess important pharmacological effects.

Subchronic toxicity evaluation of Huobahuagen extract and plasma metabolic profiling analysis combined with conventional pathology methods. J Appl Toxicol 2024; 44:201-215. [PMID: 37697829 DOI: 10.1002/jat.4532] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2023] [Revised: 08/10/2023] [Accepted: 08/10/2023] [Indexed: 09/13/2023]
Abstract
Huobahua, namely, Tripterygium hypoglaucum (Levl.) Hutch, known as a traditional Chinese herbal medicine, especially its underground parts, has been widely developed into several Tripterygium agents for the treatment of rheumatoid arthritis and other autoimmune diseases. It has sparked wide public concern about its safety, such as multi-organ toxicity. However, the toxic characteristics and damage mechanism of Huobahuagen extract (HBHGE) remain unclear. In the present study, subchronic oral toxicity study of HBHGE (10.0 g crude drug/kg/day for 12 weeks) was performed in male rats. Hematological, serum biochemical, and histopathological parameters, urinalysis, and plasma metabolic profiling were assessed. The single-dose subchronic toxicity results related to HBHGE exhibited obvious toxicity to the testis and epididymis of male rats. Furthermore, plasma metabolomics analysis suggested that a series of metabolic disorders were induced by oral administration of HBHGE, mainly focusing on amino acid (glutamate, phenylalanine, and tryptophan) metabolisms, pyrimidine metabolism, glutathione metabolism, and steroid hormone biosynthesis. Moreover, it appeared that serum testosterone in male rats treated with HBHGE for 12 weeks, decreased significantly, and was susceptible to the toxic effects of HBHGE. Taken together, conventional pathology and plasma metabolomics for preliminarily exploring subchronic toxicity and underlying mechanism can provide useful information about the reduction of toxic risks from HBHGE and new insights into the development of detoxification preparations.

Abstract
Pancreatic adenocarcinoma is a disease with no effective treatment. Chemo-resistance contributes to the dismal prognosis for patients diagnosed with the disease. This study aims to evaluate the toxicity and the effect of Caralluma europaea (C.E) extracts on cancer cell survival, apoptosis, chemo-resistance, and pro-cancer pathways, in pancreatic cancer. The acute and subacute toxicities of C.E extracts were evaluated. The cytotoxic effect on pancreatic cancer cell survival and apoptosis was determined by MTT assay and DNA fragmentation. The expression of cancer stemness markers was measured using Western blot. A molecular docking was used to test the possible effects of C.E compounds in inhibiting the Hedgehog and activating caspase-3. The hydroethanolic extract's DL50 was over 5000 mg/kg. During the subacute toxicity, only saponins extract showed some hepatic toxicity signs. Cells treated with C.E extracts combined with gemcitabine revealed an additive anti-survival activity. C.E extracts sensitized resistant MIA-PaCa-2 to gemcitabine treatment. Most of the C.E extracts downregulated the expression of cancer stemness-associated genes. Luteolin-7-O-glucoside presented the highest docking Gscore on human Smoothened. Isorhamnetin-3-O-rutinoside induced apoptosis via activation of caspase-3. C.E extracts can be considered safe in inhibiting pancreatic cancer cell survival, inducing apoptosis, and sensitizing cells to chemotherapy via Hedgehog inhibition and caspase-3 activation.Communicated by Ramaswamy H.

JOURNAL OF ETHNOPHARMACOLOGY 2023; 302:115901. [PMID: 36336220 DOI: 10.1016/j.jep.2022.115901] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Revised: 10/29/2022] [Accepted: 10/31/2022] [Indexed: 06/16/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Toxicodendron vernicifluum (Stokes) F.A. Barkley (RVS) is an economic tree species and widely distributed in East Asia. Wood parts and raw lacquers of RVS have been used in coatings, herbal medicines or food supplements, and the leaves, flowers, roots, and fruits of RVS are also widely used in medicine traditionally. Lacquer seed oil (LSO) has potential health benefits and has not previously been evaluated for safety. AIM OF THE STUDY The aim of the present study was to investigate the toxicological potential of LSO by acute and subchronic toxicity tests. MATERIALS AND METHODS The characterization of fatty acids of the LSO was carried out by gas chromatography. In the acute toxicity study, LSO was administered at single doses of 5000 or 10000 mg/kg by oral gavage. The subchronic toxicity study was conducted by daily oral administration of LSO at doses of 1250, 2500 and 5000 mg/kg/day for 30 consecutive days. The animals were evaluated for clinical observations, body weight, organ weight, feed consumption, biochemical and hematological parameters, and liver, lung, and kidney histology. RESULTS There were no mortality and toxic changes were observed in acute toxicity study. The results of subchronic toxicity showed no toxicologically significant changes in clinical observations, body weight, organ weight, biochemical or hematological parameters. Histopathologic results indicated slight hepatic steatosis and inflammatory infiltration in the rats of 5000 mg/kg/day LSO treated group. However, the histopathologic observation was not confirmed by hepatic biochemical analysis. CONCLUSIONS These results suggested that the LD50 of LSO is over 10000 mg/kg and LSO is non-toxic for SD rats in acute toxicity study. The no observed adverse effect level (NOAEL) of LSO in rats is considered to be 5000 mg/kg/day, and liver is the potential target organ of LSO for 30-day subchronic toxicity study.

Abstract
Although Sanguisorba minor has been used as herbal medicine, no study has ever examined its potential toxicity. This study investigated acute and subacute toxicities of S. minor hydroalcoholic extract (SE). In the acute toxicity test, a single oral dose (300, 2,000, and 3,000 mg/kg) of SE was given to mice. The oral administration of SE (100, 200, and 400 mg/kg for 4 weeks) was performed to evaluate subacute toxicity. After the treatments, neurobehavioral, histopathology, hematological, and biochemical parameters were monitored. In vitro cytotoxicity was also assessed. Moreover, high-performance liquid chromatography fingerprint was done for the standardization of SE. The no-observed-adverse-effect level of SE was up to 2,000 mg/kg, and the LD50 of the prepared extract was over 3,000 mg/kg. The rats exposed to the extract did not show any marked change in their body weight. The extract at used doses did not affect neuromuscular coordination. According to the hematological, biochemical, and histological examinations, no significant treatment-related adverse effect of the extract was observed, even at 400 mg/kg. Only 48 h exposure to 400 μg/mL of SE reduced the viability of PC12 cells. The findings revealed that this plant could be well-tolerated, regarded safe, and used as herbal medicine.

Abstract
The present study aimed to evaluate the acute and subacute toxicity profiles of Erodium guttatum extracts in mice using the methods described in the guidelines of the OECD. In the acute toxicity study, the LD50 value was greater than 2000 mg/kg. The subacute toxicity study of E. guttatum extracts showed no significant changes in body or organ weights. The administration of E. guttatum extracts to mice at a dose of 200 mg/kg led to an increase in white blood cells, platelets and hemoglobin. Moreover, the aqueous extract of E. guttatum only decreased liver aspartate aminotransferase (ASAT) levels at a dose of 200 mg/kg, and creatinine and urea levels did not show any significant alterations compared to the control group. Our results showed that the extracts of E. guttatum caused a slight increase in alanine aminotransferase (ALAT) and triglycerides. The histological study showed that mice treated with E. guttatum extracts experienced some histopathological changes in the liver, particularly with the methanolic extract, and slight changes in the kidneys and pancreas. Regarding the renal profile, no toxicity was observed. These results provide basic information on the toxicological profile of E. guttatum used in traditional medicine.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Moringa oleifera Lam. leaves infusion and powder are widely used by population due the nutritional and medicinal potentials, however data regarding safety of use are still inconclusive, leading to prohibition of this plant in some countries. AIM OF THE STUDY The present work investigated the nutritional and phytochemical composition, acute and 28-day repeated dose toxicity, and genotoxicity of M. oleifera leaves infusion and powder. MATERIALS AND METHODS For nutritional characterization of leaf powder, it was determined: humidity; mineral residue (ash); total lipid, protein, carbohydrate, and crude fiber contents; and total caloric value. Phytochemical composition was determined by high performance liquid chromatography (HPLC). The acute toxicity assay used Swiss female albino mice and oral administration in a single dose at 2000 and 5000 mg/kg of infusion or powder. The 28-day repeated dose toxicity assay employed female and male mice, with oral administration of infusion or powder at the doses 250, 500 and 1000 mg/kg. The animals were evaluated for body weight, water and feed consumption, biochemical and hematological parameters, and histology of the liver, spleen, and kidneys. In vivo genotoxicity and mutagenicity (2000 mg/kg) were evaluated by the comet assay and the micronucleus test, respectively. RESULTS Nutritional characterization confirmed that M. oleifera leaves are rich in proteins, carbohydrates, lipids, minerals, and fiber. HPLC indicated the presence of flavonoids and cinnamic derivatives as major polyphenols. Acute toxicity did not reveal alterations in weight gain and water and feed consumptions and no change in biochemical, hematological, and histological parameters. Behavior alterations was observed in the first 2 h after administration at 5000 mg/kg in both treatments. Infusion did not present toxicity when administered for 28 days. Conversely, the powder at 500 and 1000 mg/kg promoted liver and kidney damages observed through biochemical parameters and histopathology. Genotoxicity and mutagenicity were not detected at 2000 mg/kg. CONCLUSIONS The present study reveals that M. oleifera leaves are an important source of polyphenols and nutrients. Indiscriminate use of both infusion and crude leaf powder above 2000 mg/kg and powder at 500 and 1000 mg/kg are not recommended. Chronic toxicological studies and establishment of preparation protocols are suggested aiming to guarantee the safety in the use of M. oleifera leaves as nutraceutical by population.

Abstract
The reproductive system is essential for the structuring and transmission of genetic diversity. Understanding the reproductive biology of threatened endemic species is considered to be a crucial element for the implementation of effective conservation strategies. Given the lack of information and the insufficient state of knowledge on the reproductive system of Anacyclus pyrethrum L., a threatened medicinal species endemic to Morocco, we are the first to study the reproductive biology of two varieties of Anacyclus pyrethrum L.: Anacyclus pyrethrum var. pyrethrum (L.) Link and Anacyclus pyrethrum var. depressus (Ball.) Maire. The reproductive biology of the two varieties was examined in detail by studying the development of the inflorescence, phenology of flowering, breeding system, pollinators, production, and seed dispersal. The experimental results described in this work suggest that Anacyclus pyrethrum L. is a gynomonic species, with a mixed autogamy–allogamy reproductive regime with a high predominance of allogamy. It appears to be partially self-incompatible, with allogamy rates for Anacyclus pyrethrum var. depressus (Ball.) Maire and Anacyclus pyrethrum var. pyrethrum (L.) Link of 78.70% and 79.01%, respectively. It depends on pollination vectors to produce a large number of seeds. This study on the breeding system of Anacyclus pyrethrum L. provides a tool for developing management strategies and adequate conservation measures.

Abstract
Zizania latifolia Turcz. has long been used as a food source in Southeast Asia. The grains, stems, and leaves of Z. latifolia and its major component, tricin, have also been studied to determine their biological activities. Previously, we hydrolyzed the aerial part of Z. latifolia using an enzyme mixture to maximize the tricin content of the Z. latifolia extract. However, the safety of enzyme-treated Z. latifolia extract (ETZL; DermaNiA™) has not yet been determined. In this study, we performed an in vivo 90-day repeated-dose evaluation and genotoxicity study to assess the toxicological potential of ETZL. EZTL did not exhibit genotoxicity in the bacterial reverse mutation test, in vitro chromosomal aberration assay, or in vivo micronucleus test. Moreover, no changes in body weight or hematological and serum biological parameters were observed in male or female rats under high-dose EZTL treatment (5000 mg/kg body weight (bw)/day) for 90 days with a 4-week recovery period. Significant changes were noted in the forestomach, kidneys, and adrenal glands in the test groups, but these changes, or tendency for recovery, were not observed in the recovery group. Based on these data, the no adverse effect level was determined to be 1250 mg/kg bw/day in rats.

Abstract
Pulsed electric field (PEF) is a nonthermal technology resulting in the rupture of cell membranes and increasing the electrical conductivity and the permeability of intracellular material. There was little work about the safety of food treated by PEF. The acute, subacute oral, and genetic toxicities were investigated to explore the safety of canola oil extracted by aid of PEF treatment (PTCO). The results showed that no negative consequences were caused by PEF. PTCO was regarded as practically non-toxic with a LD50 higher than 40 g/kg bw. No oil intake-related mortality, clinical, weight gain and organ coefficient abnormalities were observed. The histopathological symptoms indicated a mild load but not obvious toxicities on liver and kidney. The 28-day subacute toxicity test confirmed that less than 10 g/kg·d bw of oil intake did not exhibit any intake-related changes in physical, physiological, biochemical, hematological, and histopathological signs. The less than 4 of atherosclerosis index suggested that no risk of cardiovascular disease caused by PTCO intake. It was speculated that the PEF treatment would not cause any safety issues to food products.

JOURNAL OF ETHNOPHARMACOLOGY 2022; 288:114986. [PMID: 35032587 DOI: 10.1016/j.jep.2022.114986] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/02/2021] [Revised: 12/11/2021] [Accepted: 01/06/2022] [Indexed: 06/14/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Epigynum auritum is mainly distributed in Southwest China, and has been used as a "dai" folk medicine with promising Besides, the leaves and barks of E. auritum have detoxifying, analgesic and relieving swelling effects. Previous studies evidenced that E. auritum was rich in pregnanes and their glycosides. However, the hypoglycemic and hypolipidemic effects of the extract from E. auritum (EAE) and its molecular mechanism are still not studied. AIM OF THE STUDY The aim of this study is to investigate the hypoglycemic and hypolipidemic effects of EAE on high-fat diet and streptozocin-induced type 2 diabetic rats. MATERIALS AND METHODS The high-fat diet and streptozocin induced type 2 diabetic model was established. The diabetic rats were treated with 70% ethanol extract of E. auritum (100 and 300 mg/kg/d) or metformin (DMBG, 100 mg/kg/d) every day for 4 weeks. Fasting blood glucose was recorded weekly. The phenotypic changes were evaluated by the measurement of biochemical indexes and immunohistochemical. The expressions of signaling-related proteins were explored by western blotting. RESULTS EAE could effectively regulate the metabolism of glucose and lipids in diabetic rats by increasing insulin sensitivity. In addition, EAE ameliorated the oxidative stress damage and further mitigated the liver, kidney, and pancreatic damage. Mechanism research results show that EAE treatment increased the phosphorylation of Akt, AMPK and GSK-3β, up-regulated the expression of GLUT-2, GLUT-4 and PPAR-α, and reduced PPAR-γ and FAS expressions. CONCLUSION EAE exhibited significant hypoglycemic and hypolipidemic effects in HFD/STZ-induced diabetes rats. The mechanism may be related to the effective upregulation of AMPK/Akt/GSK-3β pathway and the decreased expression of PPAR-γ and FAS. It could be a promising natural product with potential value for the development of drugs to prevent or treat type 2 diabetic.

Abstract
Morinda officinalis has diverse pharmacological effects and has the potential to be used as functional food and medicine. Fermentation is traditionally used to process Morinda officinalis. However, the toxicological profile of fermented Morinda officinalis (FMO) is not reported. In the present study, the toxicological characteristics of FMO were assessed for the first time. FMO did not show any genotoxicity based on the Ames test, mammalian erythrocyte micronucleus test, and mouse primary spermatocyte chromosome aberration test. FMO administered by gavage in mice and rats at a dose of 20 g/kg BW did not induce death or toxicity based on acute study, indicating that FMO could be regarded as non-toxic at the tested dose. In the 90-day subchronic toxicity study, rats fed with FMO at the maximum dose of 8 g/kg BW did not affect mortalities, BW, food consumption, organ weights, hematology, serum biochemistry, or urinalysis. The no observed adverse effect level of FMO in both sexes was not less than 8 g/kg BW/day based on subchronic toxicity. The obtained results support the safe use of FMO as functional food and medicine.

Toxicity of Tetradium ruticarpum: Subacute Toxicity Assessment and Metabolomic Identification of Relevant Biomarkers. Front Pharmacol 2022; 13:803855. [PMID: 35295336 PMCID: PMC8918793 DOI: 10.3389/fphar.2022.803855] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2021] [Accepted: 01/12/2022] [Indexed: 11/19/2022] Open
Abstract
Tetradium ruticarpum (TR) is widely used in Asia to treat gastrointestinal disorders and pain. Stir-frying with licorice aqueous extract is a traditional processing procedure of TR formed in a long-term practice and performed before clinical application, and believed to reduce TR’s toxicity. However, its toxicity and possible toxicity attenuation approach are yet to be well investigated. Subacute toxicity and metabolomics studies were conducted to help understand the toxicity of TR. The subacute toxicity assessment indicated that 3 fold of the recommended therapeutic dose of TR did not show obvious subacute toxicity in rats. Although an extremely high dose (i.e., 60 fold of the recommended dose) may cause toxicity in rats, it reversed to normal after 2 weeks of recovery. Hepatocellular injury was the major toxic phenotype of TR-induced liver damage, indicating as aspartate aminotransferase (AST) and liver index increasing, with histopathologic findings as local hepatocyte necrosis, focal inflammatory cell infiltration, slightly bile duct hyperplasia, and partial hepatocyte vacuolation. Moreover, we evaluated the impact of processing in toxicity. TR processed with licorice could effectively reduce drug-induced toxicity, which is a valuable step in TR pretreatment before clinical application. Metabolomics profiling revealed that primary bile acid biosynthesis, steroid biosynthesis, and arachidonic acid metabolism were mainly involved in profiling the toxicity metabolic regulatory network. The processing procedure could back-regulate these three pathways, and may be in an Aryl hydrocarbon Receptor (AhR) dependent manner to alleviate the metabolic perturbations induced by TR. 7α-hydroxycholesterol, calcitriol, and taurocholic acid were screened and validated as the toxicity biomarkers of TR for potential clinical translation. Overall, the extensive subacute toxicity evaluation and metabolomic analysis would not only expand knowledge of the toxicity mechanisms of TR, but also provide scientific insight of traditional processing theory, and support clinical rational use of TR.

Abstract
The U.S. National Research Council (NRC) introduced new approaches to report toxicity studies. The NRC vision is to explore the toxicity pathways leading to the adverse effects in intact organisms by the exposure of the chemicals. This study examines the toxicity profiling of the naphthalene-2-yl 2-chloro-5-dinitrobenzoate (SF5) by adopting the vision of NRC that moves from traditional animal studies to the cellular pathways. Acute, subacute, and developmental toxicity studies were assayed according to the Organization for Economic Cooperation and Development (OECD) guidelines. The stress response pathway, toxicity pathway, and adverse effects outcome parameters were analyzed by using their standard protocols. The results showed that the acute toxicity study increases the liver enzyme levels. In a subacute toxicity study, alkaline phosphatase (ALP) levels were raised in both male and female animals. SF5 significantly increases the normal sperm count in the male animals corresponding to a decrease in the abnormality count. Developmental toxicity showed the normal skeletal and morphological parameters, except little hydrocephalus was observed in developmental toxicity. Doses of 20 mg/kg in males and 4 mg/kg in females showed decreased glutathione (GSH) levels in the kidney and liver. MDA levels were also increased in the kidney and liver. However, histopathological studies did not show any cellular change in these organs. No statistical difference was observed in histamine levels, testosterone, nuclear factor erythroid two-related factor-2 (Nrf2), and nuclear factor-kappa B (NF-κB), which showed no initiation of the stress response, toxicity, and adverse effect pathways. Immunomodulation was observed at low doses in subacute toxicity studies. It was concluded that SF5 did not produce abrupt and high-toxicity levels in organs and biochemical parameters. So, it is safe for further studies.

Abstract
Background Since no effective vaccine has been developed for toxoplasmosis, prophylaxis in seronegative pregnant women and immunocompromised patients with a CD4 <100 cells/μL is highly recommended as an ideal strategy to prevent this disease. This study aimed to assess the chemical composition, in vitro, and in vivo effects of Allium sativum essential oil (ASEO) against Toxoplasma gondii RH strain. Methods The in vitro anti-Toxoplasma effects of different concentrations of ASEO (32.5, 75, 150 µg/mL) were measured by MTT assay for 0.5, 1, 2, and 3 h. Male Balb/c mice were orally administrated ASEO at the doses of 200, 400, and 600 µg/kg/day for 14 days. One day after the completion of oral drug administration, the mice in all groups were infected intraperitoneally with 1×104 tachyzoites. They were checked daily and the rate of survival was recorded. The peritoneal fluids of the mice were collected and the mean number of tachyzoites was calculated via a light microscope. The level of liver lipid peroxidation (LPO) and nitric oxide (NO), toxicity effects on the liver and kidney, and the mRNA expression levels of some pro-inflammatory cytokines such as IL-1β and IFN-γ were determined by quantitative real-time PCR. Results Different concentrations of ASEO showed a significant (p < 0.001) anti-Toxoplasma activity against T. gondii tachyzoites, and the highest efficacy was observed at the concentration of 150 µg/mL. Fourteen days of pre-treatment of infected mice with ASEO at the doses of 200, 400, and 600 µg/kg/day significantly (p < 0.001) decreased the mean number of tachyzoites and mortality rate by the 6th, 7th, and 8th days after infection, respectively. ASEO at the doses of 200, 400, and 600 µg/kg/day significantly (p < 0.05) improved the increase in the LPO and NO. Pre-treatment of mice with different doses of ASEO provoked a considerable (P < 0.001) downregulation of IL-1β and IFN-γ mRNA gene expression levels, but it had no significant toxicity on the serum levels of some liver and kidney enzymes. Conclusion The present study demonstrated the considerable prophylactic effects of ASEO that increased the survival rate of mice and reduced the parasite load in them. Our findings also showed that ASEO promotes the innate immune system, pro-inflammatory cytokines, inhibition of hepatic injury, etc. in the mice with acute toxoplasmosis. However, additional investigations are mandatory to clarify the accurate prophylactic and therapeutic anti-Toxoplasma mechanisms of ASEO as well as all its toxicity aspects, especially in clinical settings.

Abstract
Caralluma europaea (Guss.) N.E.Br. (C. europaea), is a medicinal plant used traditionally to treat diabetes mellitus (DM) in Morocco. This study aimed to investigate the in vitro antioxidant properties, glucose diffusion effects, α-amylase inhibitory activity, and pancreatic protective effects of C. europaea in experimental alloxan-induced diabetes in mice. Total phenolic contents were determined by Folin–Ciocalteu colorimetric method, total flavonoid contents were measured by aluminum chloride colorimetric assay, and tannins contents were determined by employing the vanillin method. C. europaea ethyl acetate fraction exhibited high antioxidant potential in terms of radical scavenging (DPPH) (IC50 = 0.22 ± 0.01 mg/mL), β-carotene bleaching activity (IC50 = 1.153 ± 0.07 mg/mL), and Ferric-reducing antioxidant power. Glucose diffusion was significantly inhibited by the ethyl acetate fraction at 60,120and 180 min, while the aqueous extract did not have this inhibitory effect when compared with the control group. Potent α-amylase inhibitory activity was observed in the ethyl acetate fraction and the aqueous extract in vitro and in vivo using STZ-diabetic rats. On the other hand, the administration of the ethyl acetate fraction (60 mg/kg) significantly attenuated alloxan-induced death and hyperglycemia in treated mice. Furthermore, histopathological investigations revealed that the ethyl acetate fraction protected islets of Langerhans against alloxan-induced tissue alterations. These results suggest that C. europaea exhibited an important antihyperglycemic effect via the inhibition of glucose diffusion and pancreatic α-amylase activity. In addition, the antidiabetogenic effect of C. europaea might be attributed to their polyphenol and flavonoid compounds, which could be reacted alone, or in synergy, to scavenge the free radicals produced by the alloxan.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Anneslea fragrans Wall. is traditionally used as a folk medicine in treating indigestion, fever, dysentery, diarrhea, and liver inflammation in China, Vietnam and Cambodia. However, its anti-inflammatory activity and mechanism under a safety therapeutic dose as well as the main chemical components have not yet been fully investigated. AIM OF THE STUDY This study aimed to explore the therapeutic effect and possible molecular mechanisms of aqueous-methanol extract (AFE) of A. fragrans leaves on dextran sodium sulfate (DSS)-induced ulcerative colitis (UC) mice and illustrate its potent anti-inflammatory chemical compounds. MATERIALS AND METHODS The AFE was obtained and then analyzed by high performance liquid chromatography (HPLC). Phytochemical investigation on the AFE was carried out to isolate and characterize its major components. The acute toxicity test was performed to provide the safety information of AFE. Subsequently, the protective effect of AFE on DSS-induced UC was evaluated by physiological changes, histopathological and immunohistochemical analysis, and the expressions of antioxidant enzyme, pro-inflammatory cytokines and anti-inflammatory cytokines. The expressions of target proteins in nuclear factor-kappa B (NF-κB) and mitogen-activated protein kinase (MAPK) were determined by western blot analysis. The tight junction (TJ) proteins in colon tissue were performed by immunohistochemical technique for evaluating the intestinal barrier integrity. RESULTS HPLC guided isolation of AFE resulted into two dihydrochalcones, which were elucidated as vacciniifolin (1) and confusoside (2). Acute toxicity evaluation revealed that median lethal dose (LD50) of AFE was greater than 5000 mg/kg. Furthermore, AFE significantly attenuated ulcerative colitis symptoms, suppressed myeloperoxidase activity, and increased the expression of superoxide dismutase and glutathione. AFE treatment could also reduce the levels of tumor necrosis factor-α, interleukin-1β, and interleukin-6 and increase the levels of interleukin-4 and interleukin-10 in colon tissues and serum of DSS-induced UC mice. In addition, AFE significantly increased the expression of zonula occludens-1, occludin and claudin-1, and inhibited the phosphorylation of target protein of the NF-κB and MAPK signaling pathways in colon tissue. CONCLUSION Dihydrochalcone glycosides are the major chemical constituents in AFE. AFE ameliorated DSS-induced UC in mice by inhibiting the inflammatory response via modulation of NF-κB and MAPK pathways and maintaining the intestinal barrier function, indicating that the plant A. fragrans could be used as a therapeutic candidate for ulcerative colitis.

Abstract
E Se tea, processed by the fresh leaves of Malus toringoides (Rehd.) Hughes, is a traditional herbal tea with various human benefits. The present study was aimed to evaluate the toxicity and hypolipidemic effect of aqueous-ethanol extract (EE) and hot-water extract (WE) from E Se tea. Eight main chemical constituents in EE and WE were respectively identified and quantified by UHPLC-HRMS/MS. EE is rich in TPC and TFC, while WE had higher TPS content. Both EE and WE exhibited strong antioxidant activity with no significant difference. The acute toxicity study revealed that the LD50 values were higher than 5000 mg/kg, while both WE and EE had no significant adverse effect in rats by subacute toxicity assay. However, the triglyceride (TG) content in experiment groups (male) and highest doses groups (female) significantly decreased. Furthermore, the hypolipidemic effect of WE and EE were performed on high fat diet induced hyperlipidemic rats. The result exhibited that either WE or EE could effectively regulate lipid droplet accumulation in liver, and reduce the adipocyte size. These results demonstrated that these two extracts from E Se tea could be regarded as a potential functional dietary supplement in preventing and treating diet induced metabolic diseases.

Abstract
Abstract
Background
The leaves of Jatropha tanjorensis have been found to have important application both in traditional medicine and as an edible vegetable in Nigerian soups. It is popularly employed in Nigeria for the treatment of anemia, diabetes, and malaria. The dearth of information on its toxicity prompted this study. Mice were administered single oral doses of 10, 100, 1000, 1600, 2900, and 5000 mg/kg b.wt (n = 3/group) of the extract and were observed for 24 h for any sign of toxicity and mortality in the acute toxicity study. For the sub-acute toxicity study, doses of 100, 200, and 400 mg/kg b.wt of the extract were administered to experimental rats (n = 6/group) for 28 days after which the assessment of hematological and biochemical parameters, as well as liver and kidney histology was conducted post-treatment. Body weight of the animals was also taken weekly.
Results
The result showed that percentage weight gain decreased as the dose of extract increased. The haematological and biochemical parameters showed that the extract had no toxic effect on experimental animals, though there was a non-significant dose-dependent decrease in WBC. The extract also showed potential to cause hepatotoxicity at the highest dose.
Conclusion
Though the median lethal dose of the plant extract suggests relative safety of the plant material, consuming large amounts over a prolonged time may need to be discouraged to avoid potential damage to vital organs such as the liver.

Abstract
ETHNOPHARMACOLOGY RELEVANCE Cuscuta chinensis Lam. (Convolvulaceae) had received growing attention as a traditional medicinal herb widely used for treating female impotence, abortion, male reproductive system disease and cardiovascular diseases, respectively. AIM OF THE STUDY The present study investigated the acute and sub-acute toxicities of C. chinensis water extract (CLW) in the ICR mice model. MATERIALS AND METHODS Various doses of CLW (1250, 2500, and 5000 mg/kg) were administered consecutively for 14 days to evaluate the acute toxicity level with examine mortality, general behavior, body weight, food and water intake of the mice. At the end of treatmet, macroscopic observation of the skin and major internal organs in the abdominal part and organ coefficients were taken. The same doses were administered daily for 28 days to determine the sub-acute toxicity level with examine mortality, general behavior, body weight, food and water intake of the mice. At the end of treatmet, macroscopical examination of organs, tissues, cavities, organ coefficients, pathology, hematological and biochemical parameters were carried out. RESULTS The acute toxicity test results revealed an LD 50 of over 5000 mg/kg for CLW. Similarly, no CLW-related mortality and severe toxicities were experienced in the sub-acute study. However, the treatment of CLW had a reducing effect on body weight of both male and female mice, and feed intake in female mice at the all tested doses (1250, 2500 and 5000 mg/kg). Moreover, significant effects in organ coefficients of brain, liver, lung, testis and thymus became apparent due to CLW mainly at the 2500 and 5000 mg/kg. The hematological analysis result showed a significant decrease in platelets, lymphocytes, and hematocrit. In contrast, a significant increase in the neutrophils was observed in the CLW treated groups (2500 and 5000 mg/kg). Biochemical test results showed a significant increase in aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase levels while decreasing albumin, total cholesterol and triglyceride levels after treatment of CLW mostly at the doses of 2500 and 5000 mg/kg. Mild liver toxicity in both sexes treated with 5000 mg/kg of CLW was recorded in the histopathological analysis. CONCLUSIONS Overall, our results suggested that CLW is safe at its dose lower than 1250 mg/kg, although liver toxicity from daily use may be a matter of concern.

Abstract
Houttuynia cordata has been used as a traditional medicine for more than 1500 years. It has aroused wide public concern about its safety in the past few years, for it contains various aristolactams. However, the safety of H. cordata extract remains unclear. In the present study, single dose (2000 mg/kg) and subacute (250, 500, and 1000 mg/kg/day for 28 days) oral toxicity studies of the 95% ethanol extract of H. cordata (HCE) were performed in both male and female Sprague-Dawley (SD) rats. Hematological, biochemical, histopathological parameters, and plasma metabolic profiling were assessed. The single-dose toxicity of HCE was more than 2000 mg/kg. The subacute toxicity results showed that no significant adverse effect of HCE was observed at 250 mg/kg/day. However, five rats died in 500 and 1000 mg/kg/day groups and exhibited toxicities to liver and kidney. Plasma metabolic profiling analysis suggested that a number of metabolic disturbances were induced by oral administration of HCE, focusing on energy metabolism, amino acid metabolism, and lipids metabolism. Moreover, it appeared that male rats were more susceptible to the toxic effects of HCE than female rats. Therefore, in this preliminary study, oral administration of HCE 250 mg/kg/day can be regarded as the no observed adverse effect level in rats over 28 days. However, long-term use of HCE with large doses exhibited some hepatotoxicity and nephrotoxicity in rats.

Abstract
Toxicity studies are necessary for the development of a new drug. Naphthalene is a bicyclic molecule and is easy to derivatize. In our previous study, a derivative of naphthalene (4-phenyl,3,4-dihydrobenzoquinoline-2(H)one) was synthesized and reported its in vitro activity on different enzymes. This study was a probe to investigate the toxicity potential of that compound (SF3). Acute oral (425), subacute (407), and teratogenicity (414) studies were planned according to their respective guidelines given by organization of economic cooperation and development (OECD). Acute oral, subacute, and teratogenicity studies were carried out on 2000, 5-40, and 40 mg/kg doses. Blood samples were collected for hematological and biochemical analyses. Vital organs were excised for oxidative stress (superoxide dismutase, catalase, glutathione, and malondialdehyde) and histopathological analysis. LD 50 of SF3 was higher than 2000 mg/kg. In acute and subacute studies, levels of alkaline phosphates and aspartate transaminase were increased. Teratogenicity showed no resorptions, no skeletal or soft tissue abnormalities, and no cleft pallet. Oxidative stress biomarkers were close to the normal, and no increase in the malondialdehyde level was seen. Histopathological studies revealed normal tissue architecture of the selected organs, except kidney, in acute oral and subacute toxicity studies at 40 mg/kg. The study concluded that SF3 is safer if used as a drug.

Abstract
Caralluma europaea (Guss.) N.E.Br.: (C. europaea) is a wild medicinal plant belonging to the family Apocynaceae. It is commonly used in traditional medicines for treating several diseases. The present work aims to evaluate the anti-inflammatory, antibacterial, and antifungal potentials of C. europaea fractions including hydro ethanol (ET CE), n-butanol (But CE), and polyphenol (Poly CE). The chemical composition of hydroethanol, n-butanol, and polyphenol-rich fractions from C. europaea were determined using GC-MS after silylation. The anti-inflammatory effect of hydroethanol, n-butanol, and polyphenol-rich fractions was studied by carrageenan-induced paw edema. Antibacterial and antifungal activities of hydroethanol, n-butanol, and polyphenol-rich fractions against Gram-positive bacteria, Gram-negative bacteria, and yeasts were assessed using the disc diffusion and micro-dilution assays. The findings of the chemical characterization affirmed the presence of interesting bioactive compounds in C. europaea fractions. The polyphenol-rich fraction was the best inhibitor of edema by75.68% after 6 h of treatment. The hydroethanol fraction was the most active against both bacteria and yeasts. This study contributes to society as it provides potential bioactive compounds in C. europaea extract, which may help in fighting nosocomial antibiotic-resistant microbes.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Epigynum auritum has been historically used as a "dai" or traditional medicine for the treatment of inflammation, swelling and severe pain during injury; these may reduce risk of disease and lead to healthier aging. Apart from this, Epigynum auritum extract was also used in arhritis treatment which is also a type of inflammation. Previous phytochemical studies of E. auritum revealed that steroids are main characteristic components with a number of biological activities (especially immunosuppressive and anti-inflammatory activity) Nevertheless, the underlying mechanism of the E. auritum on inflammatory diseases is still unresolved. AIM OF THE STUDY This study aimed to comparatively investigate the anti-inflammatory potential of different fractions from the extract of E. auritum (EAE), with their possible active ingredients to reveal the underlying mechanism. MATERIALS AND METHODS The EAE was fractionated by column chromatography with macroporous resin D101 which yielded six fractions. The potential anti-inflammatory properties of different fractions of EAE were evaluated in in vitro and in vivo model. The lipopolysaccharide (LPS)-induced RAW264.7 macrophages cells were used for in vitro studies however two typical acute inflammation murine models (xylene-induced ear edema and carrageenan-induced paw edema) were used for anti-inflammatory studies. The important molecular mechanisms related to inflammation were also analyzed by ELISA, western blotting and immunofluorescence. UHPLC-MS/MS was used to analyze the chemical composition of 100% EAE fraction. RESULTS Different EAE fractions (especially the Fr. 100% of MeOH:H2O) significantly reduced the productions of NO, ROS, TNF-α, and IL-6 by LPS-induced RAW264.7 macrophages and increased the expression of IL-10. The expression levels of iNOS and COX-2 enzymes were significantly down-regulated by 100% EAE fraction. Furthermore, 100% EAE fraction inhibited the phosphorylation of the ERK1/2, JNK, and p38 MAPK, and reduced the nuclear translocation of NF-κB which prevents its activation by blocking the phosphorylation and degradation of inhibitor protein of IκBα. In addition two inflammatory animal models; xylene-induced ear edema and carrageenan-stimulated paw edema were also developed with significantly ameliorated inflammatory cytokines. The treatment of these inflammatory models with 100% EAE fraction (Fr. 100%) suppressed the expressions of elevated inflammatory cytokines. Besides the UHPLC-HRMS/MS analysis was also carried out in which the androstane analogues were found to be as a main chemical components. CONCLUSION Different fractions (especially Fr. 100%) exert inhibitory effect on inflammation by regulating the release of inflammatory mediators through the NF-κB and MAPK signaling pathways. The androstane and its derivatives might be performing an important role in the observed anti-inflammatory activity. Therefore, Fr. 100% of EAE could be applied as a potential drug candidate for the prevention and treatment of inflammatory diseases.

Abstract
Melodinus henryi is a good source of terpenoid indole alkaloids, and traditionally used as a folk medicine in the treatment of meningitis and fracture. In order to further exploit their potential uses, its anti-inflammatory and immunosuppressive activities, safety evaluations and chemical profiles have been illustrated. Compared to the crude methanol extract from M. henryi and its non-alkaloidal fraction, the total alkaloidal fraction (MHTA) had the strongest anti-inflammatory and immunosuppressive activities. In the acute oral toxicity assay, the half lethal dose (LD50) of MHTA was more than 2000 mg/kg. The sub-acute toxicity assay for consecutive 28 days exhibited MHTA at a lower concentrations of less than 500 mg/kg might be regarded as safe, and might damage spleen, liver, kidney, and heart when the dose is higher than 1000 mg/kg. In addition, a phytochemical investigation on MHTA led to the isolation of 15 monoterpenoid indole alkaloids. Thus, in regard with the potent side effects of MHTA, it should be used with caution in the development of phytomedicine.

Abstract
Vascular endothelial growth factor (VEGF) had neuroprotective effects on dopaminergic (DA) neurons. In order to overcome the gastrointestinal digestion and bioaccessibility, VEGF was encapsulated with poly-lactic-co-glycolic acid nanospheres (NS) in order to prevent the VEGF degradation until its release. The caudal administration of VEGF and NS encapsulated VEGF at different doses (1.0, 10.0, and 100.0 ng/ml) on the rats with Parkinson's disease lesion was evaluated. Intravenous injected VEGF at the dose of 1 ng/ml displayed the strongest neuroprotective effect than other groups as well as the stereotaxic group. The NS encapsulated with VEGF can pass through blood-brain barrier and protect the DA neurons. There was no significant difference between intravenous injection method and stereotaxic method, while the first method is simpler and convenient. Injection of NS encapsulated with VEGF may become a valuable neurorescuing therapeutic approach for Parkinson's disease.

Oral toxicity of arjunolic acid on hematological, biochemical and histopathological investigations in female Sprague Dawley rats. PeerJ 2019; 7:e8045. [PMID: 31772835 PMCID: PMC6876537 DOI: 10.7717/peerj.8045] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2019] [Accepted: 10/16/2019] [Indexed: 11/20/2022] Open
Abstract
Background Arjunolic acid (AA) is a potent phytochemical with wider pharmacological activities. Despite potential medicinal properties on various in vitro and in vivo studies, there is still a dearth of scientific data related to its safety profile and toxicological parameters. The current study aimed to investigate acute toxicity of AA in normal female Sprague Dawley rats. Methods In this study, AA was administered orally at an individual dose of 300 and 2000 mg/kg body weight to group 1 and 2 respectively, while group 3 served as normal control. All the animals were observed for 2 weeks to determine any behavioral and physical changes. On day 15, blood was collected for hematological and biochemical investigation, later animals from all the three groups were euthanized to harvest and store essential organs for histopathological analysis. Four different staining techniques; hematoxylin and eosin, Masson trichrome, Periodic acid Schiff and Oil O Red were used to investigate any alterations in different tissues through microscopical observation. Results The results of the study showed no morbidity and mortality at two different dosage of AA treatment. Daily food & water intake, body weight, relative organ weight, hematological and biochemical parameters were detected to be normal with no severe alteration seen through microscopical investigation in the structure of harvested tissues. Our findings support the safety profile of AA, which was well tolerated at higher dose. Thus, an in-detail study on the subacute disease model is warranted.
