Zheng F, Zhao T, Liu Z. Acute and 90-day toxicological safety assessment of Shang-Ke-Huang-Shui lotion in New Zealand White rabbits. JOURNAL OF ETHNOPHARMACOLOGY 2024; 319:117027. [PMID: 37704118 DOI: 10.1016/j.jep.2023.117027] [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: 05/10/2023] [Revised: 08/02/2023] [Accepted: 08/09/2023] [Indexed: 09/15/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Shang-Ke-Huang-Shui lotion (SKHS), an experiential formula based on the theory of traditional Chinese medicine as a hospital preparation, combines Coptidis Rhizoma, Phellodendri Chinensis Cortex, Gardeniae Fructus, Arnebiae Radix, Menthae Haplocalycis Herba and Alumen. While it has acquired positive effects on the treatment of soft tissue injuries, there is no systematic safety assessment in recent studies. AIM OF THE STUDY The study aimed to investigate the acute and long-term toxicity in New Zealand White rabbits using topical administration of SKHS. MATERIALS AND METHODS In the acute toxicity study, rabbits were given topical administration of SKHS extract (2.775 g crude drug/mL) 3 times daily in normal and broken skin. In the long-term toxicity study, rabbits underwent topical administration of SKHS extract (1.390, 0.694, 0.139 g crude drug/mL) 1 time per day in normal and broken skin for 90 days. Their general behavior, body weight, food intake, biochemical and hematologic parameters, organ coefficients, and pathological morphology were analyzed. RESULTS Mild skin irritation was observed in rabbits with normal or broken skin following acute exposure to the high dose of SKHS. Evidence of toxicity was not observed in the rabbits exposed to SKHS for an extended period. Although some parameters have been significant changes, they cannot be considered treatment-related because they have remained within normal limits. CONCLUSION Topical administration of SKHS could be considered relatively safe and did not reveal any severe toxicity or side effects in this study.

Guo C, Wan L, Li C, Wen Y, Pan H, Zhao M, Wang J, Ma X, Nian Q, Tang J, Zeng J. Natural products for gastric carcinoma prevention and treatment: Focus on their antioxidant stress actions in the Correa's cascade. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2024; 123:155253. [PMID: 38065034 DOI: 10.1016/j.phymed.2023.155253] [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: 08/26/2023] [Revised: 11/15/2023] [Accepted: 12/01/2023] [Indexed: 01/17/2024]
Abstract
BACKGROUND Correa's cascade is a pathological process beginning from gastritis to gastric precancerous lesions, and finally to gastric carcinoma (GC). While the pathogenesis of GC remains unclear, oxidative stress plays a prominent role throughout the entire Correa's cascade process. Studies have shown that some natural products (NPs) could halt and even reverse the development of the Correa's cascade by targeting oxidative stress. METHODS To review the effects and mechanism by which NPs inhibit the Correa's cascade through targeting oxidative stress, data were collected from PubMed, Embase, Web of Science, ScienceDirect, and China National Knowledge Infrastructure databases from initial establishment to April 2023. NPs were classified and summarized by their mechanisms of action. RESULTS NPs, such as terpenoid, polyphenols and alkaloids, exert multistep antioxidant stress effects on the Correa's cascade. These effects include preventing gastric mucosal inflammation (stage 1), reversing gastric precancerous lesions (stage 2), and inhibiting gastric carcinoma (stage 3). NPs can directly impact the conversion of gastritis to GC by targeting oxidative stress and modulating signaling pathways involving IL-8, Nrf2, TNF-α, NF-κB, and ROS/MAPK. Among which polyphenols have been studied more and are of high research value. CONCLUSIONS NPs display a beneficial multi-step action on the Correa's cascade, and have potential value for clinical application in the prevention and treatment of gastric cancer by regulating the level of oxidative stress.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Serjania marginata Casar (Sapindaceae Family) Leaves are popularly used against abdominal pain. Antiulcer properties of S. marginata were scientifically described, however rare studies showed the antinociceptive effects of this plant. AIM OF STUDY In this study, we investigated the antinociceptive and anti-inflammatory effects of aqueous extract obtained from Serjania marginata leaves (AESM) in nociception/inflammation models. MATERIAL AND METHODS AESM was analyzed in FIA-ESI-IT-MS and Mass spectrometer LTQ XL. AESM oral administration (p.o.) (30, 100 and 300 mg/kg), dexamethasone subcutaneous injection (1 mg/kg, s.c.) and morphine (5 mg/kg, s.c.) were tested against the acetic acid-induced nociception, carrageenan-induced acute inflammatory paw edema/hyperalgesia, formalin-induced nociception and carrageenan-induced pleurisy in Swiss mice. RESULTS Flavonoids rutin was detected in the phytochemical analysis of this extract. Oral treatment of AESM 300 mg/kg significantly reduced the number of acetic acid-induced abdominal writhing. AESM (100 and 300 mg/kg) significantly inhibited formalin-induced nociception, mechanical hyperalgesia and paw edema in carrageenan-model. Furthermore, AESM significantly inhibited leukocyte migration and protein exudation in the carrageenan-induced pleurisy test. CONCLUSION This study confirms the antinociceptive, and anti-inflammatory activity of AESM, which may explain, in part, the popular use of this plant as a natural antinociceptive agent. This pharmacological action can be caused by flavonoids such as rutin and other compounds present in AESM.

Hypoglycemic effect and toxicity of the dry extract of Eugenia biflora (L.) DC. leaves. JOURNAL OF ETHNOPHARMACOLOGY 2022; 293:115276. [PMID: 35421528 DOI: 10.1016/j.jep.2022.115276] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Revised: 03/25/2022] [Accepted: 04/05/2022] [Indexed: 06/14/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The leaves of Eugenia biflora (Myrtaceae) are traditionally used by Amazonian populations for the control of diabetes. However, their chemical composition has not yet been described and pharmacological evidence has not been reported. OBJECTIVE This study aimed to identify the chemical constituents and evaluate the hypoglycemic and toxic effect of the dry extract of the E. biflora leaves (DEEB). MATERIALS AND METHODS DEEB, obtained by infusion, was analyzed using LC-HRMS and NMR, whose the catechin flavonoid was quantified using NMR. The antidiabetic effect of DEEB was evaluated according to its inhibition of the enzymes α-amylase and α-glucosidase, as well as the content of total phenols, free radical scavengingand antiglycation activities, and its in vitro cell viability. Oral maltose tolerance and chronic multiple dose tests (28 days) in streptozotocin-induced diabetic mice (STZ) were performed. The hypoglycemic effect and toxicity of this extract were evaluated in the multiple dose assay. Biochemical parameters, hemolysis, and levels of the thiobarbituric acid reactive species in the liver were investigated and histopathological analyses of the kidneys and liver were performed. RESULTS Eight phenolic compounds were identified, with catechin (15.5 ± 1.7 mg g-1) being the majority compound and a possible chemical marker of DEEB. The extract showed inhibition activity of the enzyme α-glucosidase. Chronic administration of DEEB (50 mg/kg of body weight) reduced glucose levels in diabetic animals, similar to acarbose; however, DEEB (100 and 200 mg/kg bw) caused premature death of mice by D22 of the treatment. Our data indicate that one of the mechanisms of toxicity in DEEB may be related to the aggravation of oxidative stress in the liver. This histopathological study indicated that DEEB failed to minimize the progression of the toxicity of diabetes caused by STZ. CONCLUSIONS This study demonstrated the hypoglycemic potential of E. biflora leaves. However, the prolonged use of this tea can be harmful to its users due to its considerable toxicity, which needs to be better investigated.

Toxicity and Antiulcer Properties of Ipomoea wightii (Wall.) Choisy Leaves: An In Vivo Approach Using Wistar Albino Rats. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:4328571. [PMID: 35646149 PMCID: PMC9132668 DOI: 10.1155/2022/4328571] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Accepted: 04/13/2022] [Indexed: 11/17/2022]
Abstract
Humans have been using herbs to prevent and cure various ailments since antiquity, and Ipomoea wightii is a significant medicinal plant known for its wide ethnobotanical uses. Although the plant is known to treat ulcers, there is no significant scientific validation. The present study aimed to assess the acute toxicity, subacute toxicity, and antiulcer properties of the leaf methanol extract of I. wightii (IWL). In the subacute study, the extracts were given orally at 100, 200, and 400 mg/kg doses for 28 days, and we analyzed the biochemical and histological parameters to evaluate the toxicity of IWL. Two different models were assessed to explore antiulcer properties, such as indomethacin- and ethanol-induced ulcer model. Ulcer areas and ulceration percentage histopathology of the stomach were used to study the efficacy of extracts. The acute toxicity study showed that IWL was safe to the maximum dose of 2000 mg/kg body weight. In a subacute toxicity study, the oral administration of IWL did not produce any mortality in the tested animals. The analysis of haematological, liver biochemical, kidney profile, lipid profile, and in vivo antioxidant parameters depicted that all the values were within the control limits after the experimental period and were considered nontoxic to animals. Additionally, the antiulcer study demonstrated a positive response of IWL in a dose-related manner (indomethacin- and ethanol-induced models). Macroscopic analysis showed that pretreatment with I. wightii leaf methanol extract significantly reduced the gastric lesion and decreased the ulceration area (14.52 mm2), demonstrating superior results to the positive control group (27.71 mm2). The histopathological analysis revealed that pretreatment with a high dose of 400 mg/kg of I. wightii leaf methanol extract and positive control group (omeprazole) markedly protected pathological effects, and the gastric mucosa appeared normal. In conclusion, I. wightii has solid nontoxic potential as a promising native herb for an integral therapy for the treatment of ulcers.

Abstract
Gastric cancer is the fifth most common malignancy worldwide. Serjania marginata Casar. (SM) displays anti-inflammatory properties and has been used to treat gastrointestinal disorders. In the current study, we examined whether the hydroethanolic extract of SM leaves exerted cytotoxic, mutagenic, and protective effects in non-tumor gastric epithelium cells (MNP01) and gastric adenocarcinoma cells (ACP02) in vitro and analyzed whether its action was selective. Initially, cell viability (MTT assay), cell cycle kinetics (flow cytometry), and cell proliferation (total protein content) were analyzed. In addition, genomic instability (cytokinesis-block micronucleus cytome assay), anti/pro-oxidant status (CM-H2 DCFDA probe), and transcriptional expression (RT-qPCR) of genes related to cell cycle, cell death, and antioxidant defense were also evaluated. The SM extract was cytotoxic toward MNP01 and ACP02 cells at concentrations greater than 300 and 100 μg·ml-1 , respectively, and decreased protein content only toward ACP02 cells at 200 μg ml-1 . In ACP02 cells, the SM extract at 100 μg·ml-1 associated with doxorubicin (DXR; 0.2 μg ml-1 ) clearly promoted cell cycle arrest at the G2/M phase. The extract alone was not mutagenic to either cell type and reversed DXR-induced DNA damage and H2 O2 -induced oxidative stress in MNP01 cells. The gene expression experiments showed that SM hydroethanolic extract exerts an antioxidant response via NFE2L2 activation in non-tumor gastric cells, and cell cycle arrest (G2/M) in ACP02 gastric cancer cells via the TP53 pathway. The selective action of SM indicates that it is a promising therapeutic agent to treat gastric diseases and merits further studies.

Abstract
Sida rhombifolia (Malvaceae) is popularly used as a treatment for several pathological conditions; however, there is a lack of studies that identify its compounds and that evaluate comprehensively the safety of its consumption. Therefore, the aim of this study was to determinate the phytochemical constitution of the crude extract of Sida rhombifolia (CESR), and its safety in models of acute and repeated doses (28 days) toxicity. The tested dose for the model of acute toxicity was 2000 mg/kg doses for the repeated dose model were 150, 300 e 600 mg/kg. Hematological, biochemical, histopathological and oxidative markers were investigated. HPLC-DAD-MS analysis evidenced the presence of caffeic acid, coumarin, and rutin. In the acute toxicity model the only altered parameters were tissue ROS, and AST and BUN in serum. As for the repeated dose experiment both hematological and biochemical markers remained within the values of reference for the species. Obtained results demonstrate that the CESR did not present significant toxic effects when administrated orally to male and female rats in acute and repeated doses.

Abstract
Introduction Achyranthes aspera, Chenopodium murale, Satureja punctata, Rumex abyssinicus and Aloe pulcherrima are traditionally used to treat urolithiasis in Ethiopia. However, there are limited reports on toxicity studies. Objective This study was intended to evaluate the acute and sub-acute toxicity effects of plants. Materials and Methods The crude extracts of A. aspera and C. murale leaves, S. punctata aerial parts, R. abyssinicus rhizomes, and A. Pulcherrima gel were prepared using 70 % ethanol. In acute toxicity, 125, 500 and 2000 mg/kg were tested in a stepwise manner; whereas 2000 mg/kg administrated to female rats using gavage during sub-acute toxicity. On day 14 and 28, blood samples were collected from retro-orbital sinus; liver and kidneys of each animal were collected under anaesthesia. Data were analyzed using one-way ANOVA, Dunnett's comparison test of the Graph Pad Prism. Results No mortality and significant weight loss for all extracts in both toxicity tests. In acute toxicity, C. murale extract significantly reduced hemoglobin and platelets (P < 0.01) compared with the control. Likewise, S. punctata (P < 0.05) and R. abyssinicus (P < 0.01) extracts revealed significant reduction in platelet count. An exposure to C. murale and R. abyssinicus extracts reduced the concentrations of platelet distribution width and platelet larger cell ratio (p < 0.05) during sub-acute toxicity test. The level of creatinine reduced due to A. aspera extract administrations(P < 0.05). Liver histopathological examinations revealed focal periportal hepatitis following sub-acute toxicity test of C. murale. Histopathological studies of liver demonstrated that R. abyssinicus, A. aspera and S. punctata extracts showed mild acute liver injury. A. pulcherrima was not associated with any toxicity. Conclusion C. murale extract showed hematological, and histopathological toxicity profiles in rats. Furthermore, chronic toxicity studies of A. aspera, S. punctata and R. abyssinicus extracts would be beneficial to ensure safety.

Abstract
The aim of this study was to assess the leaf aqueous extract composition of Serjania marginata and the effects of its inclusion on the diet of Nile tilapia (Oreochromis niloticus), with respect to the activity of digestive enzymes and enzymes associated with the metabolism of the liver and intestine and liver histopathology. Fish (initial mean weight, 54.36 ± 17.04 g) were divided into groups: fasting (without feeding), control (commercial feed), and treatment (commercial feed with leaf aqueous extract of Serjania marginata), and in each aquarium, there were five individuals and the fish fed ad libitum for 15 days. Treatment fish had ingested on average 224.3 mg of extract/kg of fish/day. In the extract analysis by mass spectrometry, quercitrin, isoquercitrin, A-type proanthocyanidin trimer, and quinic acid were identified. In the enzymatic activity, fish from the treatment group showed higher level of alkaline phosphatase, while the hepatotoxic markers (AST and ALT) and levels of lipase, amylase, and nonspecific protease did not differ (p > 0.05). In liver histopathological analysis, it was observed that fish from the treatment showed normal structure, while abnormalities were associated with control (fibrosis, loss of cordonal architecture, vacuolated hepatocytes with nucleus displaced to the periphery) and fasting (reduction in hepatocyte size and sinusoidal space). The intestine histopathology evidenced that the extract favored the development of goblet cells and intestinal fold height. The results indicated that the leaf aqueous extract of S. marginata assists in the structural maintenance of the liver and intestine and stimulates intestinal alkaline phosphatase production in Nile tilapia, suggesting that the identified compounds act on the liver and intestine, showing hepatoprotective effects and stimulating intestinal digestion.
