[PMID: 36525373 DOI: 10.1080/00207454.2022.2147430] [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: 03/09/2022] [Revised: 06/29/2022] [Accepted: 06/30/2022] [Indexed: 12/23/2022]
Abstract
Aims/Objectives: Cisplatin (CIS) is widely used in the treatment of various malignant tumors. The aim of study is to determine the potential protective effects of protocatechuic acid (PCA) on the brain in neurotoxicity induced by CIS in rats.Materials and methods: Forty rats were divided into four groups: 1-Control group: 2- PCA group: PCA was administered orally at a dose of 100 mg/kg/day for 5 weeks. 3-CIS group: 5 mg/kg/week of CIS was administered intraperiteonally 4-PCA + CIS group: The rats were given PCA orally daily for 5 weeks and CIS of 5 mg/kg/week. The brain tissues were used for histopathological examinations and for total antioxidant capacity (TAC), total oxidative state (TOS), oxidative stress index (OSI), tumornecrosis factor-alpha (T NF-α), interleukin 6 (IL-6) Interleukin 1 beta (IL-1β), acetylcholinesterase (AChE), glutamate, gamma aminobutyric acid (GABA), dopamine analyzes in ELISA. WBC, RBC, hemoglobin and hematocrit levels were measured.Results: PCA + CIS group compared to CIS group TOS, OSI, T NF-α, IL-6, IL-1β, AChE, glutamate, WBC levels decreased significantly, while TAC and GABA levels increased statistically significant. With this study, P CA corrected the deterioration in the oxidant / antioxidant status, suppressed neuro-inflammation, decreased AChE activity, partially normalized neurotransmitters, and decreased the increased WBC count. Necrosis seen in the CIS group in histopathological examinations was never seen in the PCA + CIS group.Conclusions: PCA may provide therapeutic benefit when used in conjunction with CIS.

The preventive effects of Centaurea maroccana Ball. extract against oxidative stress induced by cisplatin in mice brains: in vitro and in vivo studies. Drug Chem Toxicol 2023; 46:1162-1175. [PMID: 36330673 DOI: 10.1080/01480545.2022.2139841] [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: 03/28/2022] [Revised: 09/28/2022] [Accepted: 10/15/2022] [Indexed: 11/06/2022]
Abstract
Since antiquity, Centaurea species have been used in folk medicine to treat several diseases owing to their potential biological activities that distinguish this genus such as antioxidant, anticancer, and anti-inflammatory effect. The current study aimed to investigate the possible neuroprotective effects of the n-butanol extract of Centaurea maroccana (BECM) against cisplatin (CP) induced neurotoxicity in mice. BECM's potential neuroprotective properties were studied in vitro and in vivo models. Male Swiss albino mice were orally received BECM (200 mg/kg) for 10 days before a single intraperitoneal injection of cisplatin (8 mg/kg). Vitamin E (100 mg/kg) was given daily by gavage as a positive control. In vitro results revealed that BECM inhibited lipid peroxidation (LPO) levels and acetylcholinesterase (AChE) activity. In vivo findings showed that BECM pretreatment was able to regulate lactate dehydrogenase (LDH) levels and to improve CP-induced cholinergic dysfunction by inhibiting AChE activity in mice brains. Moreover, BECM attenuated CP-provoked oxidative stress by suppressing LPO levels, increasing total antioxidant capacity (TAC) and enhancing the activities of antioxidant enzymes (catalase (CAT), superoxide dismutase (SOD), reduced glutathione (GSH), glutathione peroxidase (GPx) and glutathione S-transferase (GST)) in both brain cytosolic and mitochondrial fractions. The histological analysis exhibited neurotoprotective effect of BECM by protecting the cerebral cortex and reducing the histomorphological alterations resulted by cisplatin. Interestingly, our extract achieved neuroprotection comparable to vitamin E in most evaluated parameters. It appears that protective potency of BECM against CP-induced neurotoxicity could be related to its richness in polyphenols confirmed by liquid-chromatography tandem mass spectrometry analysis (LC-MS/MS).

Mongkolpobsin K, Sillapachaiyaporn C, Nilkhet S, Tencomnao T, Baek SJ. Stigmasterol isolated from Azadirachta indica flowers attenuated glutamate-induced neurotoxicity via downregulation of the Cdk5/p35/p25 signaling pathway in the HT-22 cells. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2023; 113:154728. [PMID: 36898255 DOI: 10.1016/j.phymed.2023.154728] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Revised: 12/04/2022] [Accepted: 02/22/2023] [Indexed: 06/18/2023]
Abstract
BACKGROUND Glutamate, an excitatory neurotransmitter, was elevated in the brain of neurodegenerative disease (ND) patients. The excessive glutamate induces Ca2+ influx and reactive oxygen species (ROS) production which exacerbates mitochondrial function, leading to mitophagy aberration, and hyperactivates Cdk5/p35/p25 signaling leading to neurotoxicity in ND. Stigmasterol, a phytosterol, has been reported for its neuroprotective effects; however, the underlying mechanism of stigmasterol on restoring glutamate-induced neurotoxicity is not fully investigated. PURPOSE We investigated the effect of stigmasterol, a compound isolated from Azadirachta indica (AI) flowers, on ameliorating glutamate-induced neuronal apoptosis in the HT-22 cells. STUDY DESIGN To further understand the underlying molecular mechanisms of stigmasterol, we investigated the effect of stigmasterol on Cdk5 expression, which was aberrantly expressed in glutamate-treated cells. Cell viability, Western blot analysis, and immunofluorescence are employed. RESULTS Stigmasterol significantly inhibited glutamate-induced neuronal cell death via attenuating ROS production, recovering mitochondrial membrane depolarization, and ameliorating mitophagy aberration by decreasing mitochondria/lysosome fusion and the ratio of LC3-II/LC3-I. In addition, stigmasterol treatment downregulated glutamate-induced Cdk5, p35, and p25 expression via enhancement of Cdk5 degradation and Akt phosphorylation. Although stigmasterol demonstrated neuroprotective effects on inhibiting glutamate-induced neurotoxicity, the efficiency of stigmasterol is limited due to its poor water solubility. We conjugated stigmasterol to soluble soybean polysaccharides with chitosan nanoparticles to overcome the limitations. We found that the encapsulated stigmasterol increased water solubility and enhanced the protective effect on attenuating the Cdk5/p35/p25 signaling pathway compared with free stigmasterol. CONCLUSION Our findings illustrate the neuroprotective effect and the improved utility of stigmasterol in inhibiting glutamate-induced neurotoxicity.

Immunomodulatory, apoptotic and anti-proliferative potentials of sildenafil in Ehrlich ascites carcinoma murine model: In vivo and in silico insights. Int Immunopharmacol 2023; 119:110135. [PMID: 37080065 DOI: 10.1016/j.intimp.2023.110135] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2023] [Revised: 03/23/2023] [Accepted: 03/31/2023] [Indexed: 04/22/2023]
Abstract
Sildenafil is a potent phosphodiesterase-5 (PDE5) inhibitor that effectively inhibits cGMP and increases the strength of nitric oxide. PDE5 was overexpressed in several carcinomas, including breast cancer, which inhibited tumor growth and cell division. The current research aims to investigate the in vivo sildenafil's immunomodulatory and antineoplastic potentials against Ehrlich Ascites Carcinoma. This study looked at the effects of sildenafil mono-treatment and co-treatment with cisplatin; tumor cell count, viability and the inhibition rate were determined. Apoptosis, cell cycle distribution, alterations in tumor cells and splenocytes proliferation, changes in splenocytes immunophenotyping using flowcytometry, plasma levels of malondialdehyde (MDA), reduced glutathione (GSH), interferone (IFN)-γ, granzyme B, alanine aminotransferase (ALT), aspartate aminotransferase (AST), urea, creatinine and hematological alterations were detected. Additionally, docking study was conducted to get further insights on how Sildenafil exerts its activity. Sildenafil mono-treatment and co-treatment with cisplatin markedly reduced tumor cell count, viability, growth rate and proliferative capability accompanied by apoptosis enhancement and G0/G1 and sub G1 cells cycle arrest. Fortunately, sildenafil evoked efficient cellular immune response by increasing plasma levels of granzyme B and IFN-γ, proportion of splenic T cytotoxic (CD3+CD8+) and T helper (CD3+CD4+), accompanied by decrease in the proportion of splenic regulatory T cells. . Moreover, in silico data suggest LcK and MAPKs as the potential targets of sildenafil. Furthermore, sildenafil rebalanced the oxidant-antioxidant status by decreasing MDA and increasing GSH plasma levels. Sildenafil successfully retrieved various hematological values besides renal and hepatic functions in EAC-bearing animals. In conclusion, our results suggest that sildenafil could be potential safe anti-tumor agent with immuno-modulatory properties against Ehrlich ascites carcinoma.

Abstract
The present study involves investigation of Azadiracta Indica flowers with respect to its pharmacognostic properties, phytochemical screening, and its application as anti-oxidant, anti-biofilm, and anti-microbial agent. The Pharmacognostic characteristics were evaluated with respect to moisture content, total ash content, acid, and water-soluble ash content, swelling index, foaming index, and metal content. The macro and micronutrient content of the crude drug was estimated by AAS and Flame photometric methods and it gives the quantitative estimation of minerals, where calcium is present in abundance (88.64 mg/L). Soxhlet extraction was carried out in the increasing order of polarity of the solvent viz Petroleum Ether (PE), Acetone (AC), and Hydroalcohol (20 %) (HA) to extract the bioactive compounds. The characterization of the bioactive compounds of all the three extract have been carried out using gcms and lcms. The presence of 13 major compounds have been identified in PE extract and 8 compounds in AC extract using gcms studies. The HA extract is found to contain polyphenols, flavanoids, and glycosides. The antioxidant activity of the extracts was evaluated by DPPH, FRAP, and Phosphomolybdenum assay. This reveals that HA extract shows good scavenging activity than PE and AC extracts which is well correlated with the bioactive compounds, especially phenols which are present as a major component in the extract. The anti-microbial activity was investigated via Agar well diffusion method for all the extracts. Among all the extracts HA extract shows good antibacterial activity with MIC of 25 μg/mL and AC extract shows good anti-fungal activity with MIC of 25 μg/mL. The antibiofilm assay confirms that the HA extract shows good biofilm inhibition about 94 % among other extracts when tested on human pathogens. The results confirm that the HA extract of A. Indica flowers will be an excellent source of natural anti-oxidant and also antimicrobial agents. This paves the way for its potential uses in herbal product formulation.

J Adv Vet Anim Res 2022; 9:359-368. [PMID: 36382046 PMCID: PMC9597922 DOI: 10.5455/javar.2022.i603] [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: 01/14/2022] [Revised: 07/13/2022] [Accepted: 07/13/2022] [Indexed: 01/25/2023] Open
Abstract
OBJECTIVE The research was designed to assess the consequences of Azadirachta indica aqueous leaf extract (AILE) on neuropathic pain in Wister rats and the role of the ATP-dependent potassium channel (KATP) as an underlying mechanism. MATERIALS AND METHODS This experimental layout was conducted on Wistar rats (n = 120) having 150 to 200 gm of body weight. On the foundation of the experimental design, rats were divided into group I (normal saline, 5 ml/kg/body weight) and group II (sham surgery and treatment with NS), group III [chronic constriction injury (CCI) in the sciatic nerve; and treated with NS], group IV (CCI and treated with AILE 400 mg/kg body weight), Group V (CCI, pretreated with Glibenclamide 15 mg/kg followed by treated with AILE 400 mg/kg). All the treatments were given once daily for a consecutive 21 days via the oral route, except Glibenclamide. Glibenclamide was given once through the intraperitoneal route on the day of the experiment. RESULTS Based on the neuropathic pain evaluation test, all groups were again sub-divided into subgroup "a" (walking tract analysis), "b" (cold tail immersion test), "c" (Von Frey test), and "d" (hot plate test). AILE showed a significantly higher sciatic functional index (p < 0.05) in walking track analysis, tail flick latency (p ≤ 0.05) in the cold tail immersion test, and paw withdrawal threshold (p ≤ 0.05) in the Von Frey test compared to CCI control. In addition, a nonsignificant difference in all these above-mentioned variables between the rats with CCI plus AILE and the CCI plus AILE plus glibenclamide group indicated that the KATP channel was not involved in the beneficial analgesic effects of AILE. CONCLUSIONS The outcome of the present study indicates that AILE prevented worsening of neuropathic pain after chronic constriction injury in the sciatic nerve of Wistar rats in which the KATP channel was not involved.

Abstract
Column chromatography afforded the isolation of seven secondary metabolites (1-(2,4,6-trihydroxy phenyl)-ethanone-4-O-β-d-glucopyranoside, naringenin-7-O-β-d-glucopyranoside, kaempferol-3-O-α-l-rhamnoside, kaempferol-3-O-β-d-glucopyranoside, quercetin-3-O-β-d-glucopyranoside, quercetin-3-O-β-d-galactopyranoside, rutin) from the ethyl acetate (ET) fractions of Morus macroura Miq. stems (S), leaves (L), and fruits (F). Their identification based on ultraviolet (UV), electron ionization (EI), electrospray ionization-mass spectrometry (ESI-MS), and 1D and 2D NMR data. In addition, profiling of ET fractions using ultraperformance liquid chromatography-electrospray ionization-tandem mass spectrometry (UPLC-ESI-MS/MS) resulted in the identification of 82 compounds belonging to different classes, mainly polyphenolic constituents. Chemical profiling as well as molecular docking directed us to biological evaluation. Interestingly, the ET-L fraction exhibited a robust cytotoxic activity against HepG-2, MCF-7, and HELA cell lines. Also, it displayed a neuromodulatory activity against cisplatin neurotoxicity in rats by ameliorating the neurobehavioral dysfunction visualized in the open field and Y-maze test and modulating the neurochemical parameters such as brain amino acid levels (glutamate, aspartate, serine, and histidine), oxidative stress markers (GSH, MDA, and 8-hydroxy-2'-deoxyguanosine), and purinergic cell energy (adenosine triphosphate (ATP) and adenosine monophosphate (AMP)). In conclusion, the isolated compounds (kaempferol-3-O-β-glucoside and quercetin-3-O-β-glucoside) from the ET-L fraction could serve as potent anticancer agents due to their strong antioxidant, in vitro cytotoxicity, and in vivo neuroprotective activity.

Quercetin Alleviates Red Bull Energy Drink-Induced Cerebral Cortex Neurotoxicity via Modulation of Nrf2 and HO-1. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2021; 2021:9482529. [PMID: 34754366 PMCID: PMC8572608 DOI: 10.1155/2021/9482529] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Revised: 09/23/2021] [Accepted: 10/13/2021] [Indexed: 01/19/2023]
Abstract
The current work was aimed at evaluating the ameliorative role of quercetin (QR) on the possible toxicity of Red Bull energy drink (RB-Ed) in the cerebral cortex of rats. To achieve the goal, the rats were allocated into 4 groups. The first group received distilled water as control. Groups II and III were given Red Bull energy drink alone and in combination with quercetin, respectively. The fourth group served as recovery to group II. The experimental duration was four weeks for all groups whereas the recovery period of group IV was two weeks. QR upregulated the mRNA and protein expression levels of nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) genes, which can protect against RB-Ed neurotoxicity. Moreover, by reducing the thiobarbituric acid reactive substance and increasing the total antioxidant capacity levels, QR protected rats' cerebral cortex against Red Bull energy drink-induced oxidative damage. Quercetin also inhibited RB-Ed-induced histomorphological degeneration which was confirmed by the increase in the intact neurons and the rise in the neuron-specific enolase immunoreaction. QR increased the reduction of the brain-derived neurotrophic factor that was elicited by RB-Ed and acts as an anti-inflammatory agent by reducing the proinflammatory marker, interleukin 1 beta and DNA damage markers, heat shock protein 70, and 8-hydroxydeoxyguanosine. It could be concluded that the alleviating impacts of QR on RB-Ed neurotoxicity in rats could be related to the modulation of Nrf2 and HO-1 which in turn affects the redox status.

Abstract
Summary
A global society, including developed countries, continues to struggle with fatal diseases that are difficult to treat with Western medicine. A variety of infectious diseases have existed for ages, but in Africa they had been limited thanks to the Indigenous Knowledge System (IKS) prior to the introduction of cosmopolitan medicine. Influenza virus repression has been demonstrated by a number of herbal antivirals, yet the invaluable therapeutic potential of herbal medicine has been underestimated. Despite various reliable methods offered by Western medicine, the globally destructive COVID-19 pandemic requires a successful fight. The wisdom of African IKS used in tackling epidemics that have broken out in the past is brought to mind again. Pneumonia – a COVID-19 symptom, could be treated with polyherbal fomentation. Selected plants cultivated across Nigeria for hydrotherapy are under consideration to be used in proper doses. Given the potential associated with IKS, a multi-disciplinary approach involving experts in phytomedicine, ethnobotany, phytochemistry, plant physiology and ecology is necessary to unlock the therapeutic potential of traditional medicine.

Chemical and Green ZnO nanoparticles ameliorated adverse effects of cisplatin on histological structure, antioxidant defense system and neurotrophins expression in rat hippocampus. J Chem Neuroanat 2021; 116:101990. [PMID: 34146667 DOI: 10.1016/j.jchemneu.2021.101990] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Revised: 06/14/2021] [Accepted: 06/14/2021] [Indexed: 11/20/2022]
Abstract
Cisplatin (CP) is a chemotherapy agent used in the treatment of cancer, but it has various side effects, in particular, neurotoxicity. Zinc oxide nanoparticles (ZnO NPs) are a potent antioxidant. However, there is limited knowledge about the protective effects of ZnO NPs against CP-induced hippocampal toxicity. The present study aimed to explore the potential protective effects of ZnO NPs against CP-induced oxidative stress, loss of neurotrophins support, and tissue damage in the hippocampus of the rats. Eighty adult male Wistar rats were dividing into ten groups including: control (Con), sham, ZnO Bulk (ZnB), chemical ZnO NPs (ChZnO NPs), Green ZnO NPs (GrZnO NPs), CP, CP + ZnB, CP + ChZnO NPs, CP + GrZnO NPs and CP + AE. CP was administrated (5 mg/kg/weekly) for four weeks, and animals were treated simultaneously with different forms of ZnO (5 mg/kg/day). At the end of the experiment, the activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), malondialdehyde (MDA), changes of reduced glutathione (GSH), oxidized glutathione (GSSG) and GSH/GSSG ratio, histological changes, expression of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) genes were assessed in the hippocampus. The results revealed that a decrease in BDNF and NGF mRNA expression, GSH concentration and GSH/GSSG ratio, increasing of GSSG and MDA levels, and neuronal loss in the CP-treated rats were reversed following the administration of different forms of ZnO, especially Gr ZnO NPs and ch ZnO NPs. Co-administration of ZnO NPs to CP-treated rats restored the suppressive effects of CP on activities of antioxidant enzymes (SOD, GPX, CAT). The results showed that in most of the evaluated factors, Gr ZnO NPs showed a greater protective effect than other forms of ZnO. The results suggest that ZnO NPs, in particular Green ZnO NPs (GrZnO NPs) had more potential protective effects against CP-induced oxidative stress, inadequate support neurotrophin and tissue damage in rat hippocampus.

Abstract
OBJECTIVES This study was designed to investigate the possible antioxidant, antiapoptotic and neuroprotective effects of nobiletin on cisplatin-induced neurotoxicity rat model by evaluating neurotrophins, antioxidants and histopathology. METHODS Forty male Wistar Albino rats were divided into four groups: control, cisplatin (CIS), cisplatin + nobiletin (CIS + NOB) and nobiletin + cisplatin (NOB + CIS). CIS + NOB was applied nobiletin (10 mg/kg, i.p.) during the last four days whereas NOB + CIS was applied nobiletin during the first four days of the study. Cisplatin (4 mg/kg, i.p. twice a day) was administered to the experimental groups on the 5th day of the study. All rats were sacrificed on the 10th day of the study. BDNF, NGF, G6PD, GPx, tGSH and MDA levels were determined in brain. In addition, routin histolopathological analysis and caspase-3 immunoreactivity assay were conducted. RESULTS BDNF concentrations increased in nobiletin-administered groups, compared to Control and CIS and that the increase was statistically significant in NOB + CIS (p < 0.05). It was also found that G6PD activity increased (p < 0.05) in the nobiletin-administered groups, compared to control and CIS. Histopathologically, neuronal degeneration, oedema and gliosis increased in CIS compared to Control, and nobiletin administration decreased neuronal degeneration and oedema compared to CIS (p < 0.05). Cisplatin increased (p < 0.05) caspase-3 immunoreactivity in cerebrovascular endothelium and neurons compared to Control, while nobiletin administration decreased caspase-3 immunoreactivity in cerebrovascular endothelium. Caspase-3 immunoreactivity in neurons decreased only in NOB + CIS (p < 0.05). CONCLUSION Nobiletin increased BDNF concentration and G6PD activity in brain and when evaluated together with histopathological and immunohistochemical findings, it may have antioxidant, antiapoptotic and neuroprotective effects against cisplatin.

Background
Chemotherapy is associated with male infertility. Cisplatin (CP), an antineoplastic agent has been successfully used for the treatment of diverse kinds of malignancies, however, the use of this effective agent could induce oxidative stress injury, nephrotoxicity, hepatotoxicity, and testicular damage. Combined CP chemotherapy with plant extracts can diminish the toxicity and enhance the antitumor efficacy of the drug. The objective of the study was to determine the protective effect Lophira lanceolata leaf extract (LLLE) on CP-induced toxicity on male reproductive organs.
Methods
The study was carried out with 30 (n = 30) male Wistar rats (Rattus norvegicus). The rats were randomly assigned into 6 groups of 5 rats each. Rats in group 1 (Control) were administered distilled water per os. Rats in group 2 were administered 5 mg/kg of CP intraperitoneally (i.p). Rats in groups 3 and 4 were administered per os LLLE at the doses of 200 and 400 mg/kg body weight and rats in groups 5 and 6 were administered 5 mg/kg body weight of CP + LLLE at the doses of 200 and 400 mg/kg body weight respectively.
Results
The results showed a significant decrease in the sperm parameters in the group treated with CP alone when compared with the control and there in the sperm parameters in the groups administered CP + LLLE. The body and organ weights of the rats were significantly (p < 0.05) decreased in the CP treated group relative to the control. However, there was an increase in the weight of the organs in the LLLE pretreated groups. The photomicrographs showed degenerative changes in the testicular tissues of the rats administered CP alone whereas the group pretreated with the LLLE showed amelioration induced by the CP. Our study revealed that CP treatment has deleterious effects on sperm parameters and testicular tissues and the accessory sex organs (Epididymis, prostate, seminal vesicles) of the rats. Oral administration of LLLE at 200 and 400 mg/kg bodyweight for 26 days conferred protective effects against testicular damage induced by CP.
Conclusion
This study revealed that pretreatment with LLLE protected against CP-induced testicular toxicity.

Abstract
Cisplatin has dramatically improved the survival rate of cancer patients, but it has also increased the prevalence of hearing and neurological deficits in this population. Cisplatin induces ototoxicity, peripheral (most prevalent) and central (rare) neurotoxicity. This review addresses the ototoxicity and the neurotoxicity associated with cisplatin-based chemotherapy, providing an integrated view of the potential protective agents that have been evaluated in vitro, in vivo and in clinical trials, their targets and mechanisms of protection and their effects on the antitumor activity of cisplatin. So far, the findings are insufficient to support the use of any oto- or neuroprotective agent before, during or after cisplatin chemotherapy. Despite their promising effects in vitro and in animal studies, many agents have not been evaluated in clinical trials. Additionally, the clinical trials have limitations concerning the sample size, controls, measurement, heterogeneous groups, several arms of treatment, short follow-up or no blinding. Besides that, for most agents, the effects on the antitumor activity of cisplatin have not been evaluated in tumor-bearing animals, which discourages clinical trials. Further well-designed randomized controlled clinical trials are necessary to definitely demonstrate the effectiveness of the oto- or neuroprotective agents proposed by animal and in vitro studies.

Protective Role of Epigallocatechin Gallate in a Rat Model of Cisplatin-Induced Cerebral Inflammation and Oxidative Damage: Impact of Modulating NF-κB and Nrf2. Neurotox Res 2019; 37:380-396.

Abstract
Cisplatin is a widely used chemotherapeutic agent in treating various types of cancers. However, it can induce neurotoxicity and nephrotoxicity, limiting its dose and clinical use. Although previous studies indicated the direct link between cisplatin-induced central neurotoxicity and oxidative stress, the exact mechanism is not completely understood. Therefore, herein we investigated the effects of prophylactic and concurrent treatment with (-)-epigallocatechin-3-gallate (EGCG), a natural polyphenolic neuroprotective antioxidant, on cisplatin-induced brain toxicity in rats to delineate its molecular mechanism of action. We found that cisplatin initiated a cascade of genetic, biological, and histopathological changes in the brain cortex, inducing inflammatory cytokines, appearance of scattered inflammatory cells, nitro-oxidative stress, and apoptotic proteins in the cerebral cortex. However, EGCG not only protected against cisplatin-induced inflammatory burden but also ameliorated the induction of nitro-oxidative stress and apoptotic proteins triggered by cisplatin in the cerebral cortex of pre- and co-treated rats with respect to their unprotected counterparts. EGCG anti-inflammatory effect here may be attributed to the downregulation of nuclear factor kappa B (NF-κB). Additionally, this natural polyphenol significantly ameliorated cisplatin-elicited reduction in cerebral cortex brain-derived neurotrophic factor and acetylcholine esterase. Upregulation of nuclear factor erythroid 2-related factor 2 (Nrf2) and its downstream heme oxygenase-1 (HO-1) by EGCG prophylactic and concurrent administration here seems also to play a key role in the protective impact of EGCG against cisplatin toxicity through enhancing total antioxidant capacity. Thus, EGCG can be used as a promising prophylactic adjuvant for preventing the development of brain inflammation and oxidative damage associated with cisplatin chemotherapy.

Abstract
BACKGROUND Neurotoxicity is a major obstacle to the effectiveness of cisplatin (CDDP) in cancer chemotherapy. Oxidative stress and inflammation are considered to be the major mechanisms involved in CDDP-induced neurotoxicity. The rationale of our study was to investigate the efficacy of N-acetylcysteine (NAC) at two different doses in the management of CDDP-induced toxicity in rat brain by monitoring its antioxidant and anti-inflammatory effects. METHODS Thirty-five male rats were divided into five groups (n=7) as follows: control group (0.5 mL saline), NAC100 group (100 mg/kg), CDDP group (8 mg/kg), NAC50-CDDP group (50 mg/kg NAC and 8 mg/kg CDDP), and NAC100-CDDP group (100 mg/kg NAC and 8 mg/kg CDDP). NAC was administered for 20 consecutive days, while CDDP was injected once on day 15 of the treatment protocol. RESULTS The neurotoxicity of CDDP was evidenced by a marked increase in acetylcholinesterase and monoamine oxidase activities. It also induced oxidative stress as indicated by increased levels of lipid peroxidation, nitric oxide, and protein carbonyl with a concomitant decline in reduced glutathione, glutathione peroxidase, glutathione S-transferase, superoxide dismutase, and catalase in the brain. Moreover, CDDP enhanced the synthesis of pro-inflammatory cytokines such as tumor necrosis factor-α, interleukin-1β, and interleukin-6. Treatment with NAC at the two selected doses significantly attenuated CDDP-induced changes in the brain cholinergic function, improved the brain oxidant/antioxidant status, and also reversed the overproduction of pro-inflammatory cytokines in brain and serum. CONCLUSION NAC could serve as an appropriate and safe complementary therapeutic agent to attenuate the toxicity of CDDP in the brain and therefore improve its outcomes in chemotherapy.

Abstract
Cornelian cherry (Cornus mas) is a valuable source of phenolic antioxidants. The present study was aimed to investigate whether Cornus mas fruit hydro-methanolic extract (CMFE) can modulate the cisplatin-induced changes in liver antioxidant enzymes and histological structure. Forty Wistar rats were divided into a control group, cisplatin (Cis) group, CMFE group, CMFE 300 + Cis group, and the CMFE 700 + Cis group. After the intervention, blood and tissue samples were taken for biochemical and histopathological analysis. Cis caused reduction in the activity of liver antioxidant enzymes including SOD, GPx, TAC, and CAT and increased that of MDA. Moreover, exposure to Cis caused a reduction in serum level of AST, ALT, and ALP and a rise in serum level of GGT. Oral administration of CMFE for 16 days in the two different dosages at 300 and 700 mg/kg improved the Cis-induced changes of liver enzymes activity and serum enzymes level. Evaluating the histological structure of liver tissue, it was found that treatment by CMFE could ameliorate the Cis-induced changes to near normal histology. The results showed antioxidant and phenol contents in Cornus mas fruit could improve Cis-induced oxidative stress and liver histologic changes in rats.

Abstract
Glutamate receptors play a crucial role in the central nervous system and are implicated in different brain disorders. They play a significant role in the pathogenesis of neurodegenerative diseases (NDDs) such as Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis. Although many studies on NDDs have been conducted, their exact pathophysiological characteristics are still not fully understood. In in vivo and in vitro models of neurotoxic-induced NDDs, neurotoxic agents are used to induce several neuronal injuries for the purpose of correlating them with the pathological characteristics of NDDs. Moreover, therapeutic drugs might be discovered based on the studies employing these models. In NDD models, different neurotoxic agents, namely, kainic acid, domoic acid, glutamate, β-N-Methylamino-L-alanine, amyloid beta, 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine, 1-methyl-4-phenylpyridinium, rotenone, 3-Nitropropionic acid and methamphetamine can potently impair both ionotropic and metabotropic glutamate receptors, leading to the progression of toxicity. Many other neurotoxic agents mainly affect the functions of ionotropic glutamate receptors. We discuss particular neurotoxic agents that can act upon glutamate receptors so as to effectively mimic NDDs. The correlation of neurotoxic agent-induced disease characteristics with glutamate receptors would aid the discovery and development of therapeutic drugs for NDDs.

Abstract
The present study was aimed to explore the protective role of Aloe vera gel extract against hepatic and renal damage caused by X-ray exposure to mice. Male balb/c mice were divided into four groups: control, Aloe vera gel extract [AV] (50 mg/ kg b.w on alternate days for 30 days), X-ray (2 Gy) and AV + X-ray. X-ray irradiation enhanced the serum levels of liver function indices and chromosomal abnormalities in liver. Kidney function markers were found to be deranged and were accompanied by reduced glomerular filtration rate indicating renal dysfunction. Irradiation caused histopathological and biochemical alterations in both tissues which was associated with enhanced reactive oxygen species (ROS), lipid peroxidation (LPO) levels, lactate dehydrogenase (LDH) activity and enhanced apoptosis as revealed by TUNEL assay and DNA fragmentation. The administration of Aloe vera gel extract to X-ray exposed animals significantly improved their hepatic and renal function parameters which were associated with a reduction in ROS/LPO levels, LDH activity and chromosomal abnormalities as compared to their irradiated counterparts. In vitro assays revealed effective radical scavenging ability of Aloe vera gel extract, which may be linked to its potential in exhibiting antioxidant effects in in vivo conditions. This data suggested that Aloe vera may serve to boost the antioxidant system, thus providing protection against hepatic and renal damage caused by X-ray.

Abstract
In the present investigation, the effect of olive leaf extract (OLE) on testicular damage induced in rats by an intraperitoneal injection of cisplatin (cis-diamminedichloroplatinum (CDDP)) at a dose of 5 mg/kg was tested. Rats were randomly divided into 4 groups: control, CDDP, OLE, and OLE + CDDP. After 5 days of CDDP treatment, body and testicular weights, histopathological alteration, and serum male sex hormone levels were determined. In addition to the biochemical and immunohistochemical changes in the testes, CDDP caused the disorganization of germinal epithelium and apoptosis by inducing Bax and inhibiting Bcl-2 protein expression. Testicular weights, catalase, serum testosterone, testicular enzymatic (including glutathione peroxidase, glutathione reductase, and superoxide dismutase) along with nonenzymatic (glutathione) antioxidants, and levels of luteinizing and follicle-stimulating hormones were significantly reduced in addition to a significant increase in testicular malondialdehyde and nitrite/nitrate levels when compared with the control group. OLE treatment markedly attenuated both biochemical and histopathological changes. The reproductive beneficial effects of OLE were mediated, at least partly, by inducing the nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase 1 (HO-1) pathway.

Abstract
Objective: The objective of the study was to investigate the effect of daidzein flavonoid on cisplatin (CP)-induced hematotoxicity and hepatotoxicity in experimental rats. Materials and Methods: The Wistar rats were randomly divided into four equal groups: Normal (saline 1 ml p.o.), CP (7.5 mg/kg once intraperioteneally on 16th day), test group of low dose (combination of CP and daidzein 20 mg/kg p.o. for 21 days), and test group of high dose (combination of CP and daidzein 40 mg/kg p.o. for 21 days). Blood samples were collected on 22nd day from each rat and subjected for evaluation of hematological parameters such as red blood corpuscles (RBC), white blood corpuscles, hemoglobin (Hb) and platelets, and serum biomarkers such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP). Liver of each rat was excised and subjected for antioxidants evaluation such as malonyl dialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD), catalase, and histopathological study. Results: Daidzein had a significant (P < 0.001) beneficial role in CP-induced hemotoxicity by increasing RBC, Hb, packed cell volume, and platelets. Daidzein also exhibited a significant (P < 0.001) protection against CP-induced hepatotoxicity by decreasing ALT, AST, ALP, and MDA level and by elevating the GSH, SOD, and catalase. Conclusions: Daidzein attenuates CP-induced oxidative stress on blood cells and antioxidants in rats.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2017; 14:ijerph14121592. [PMID: 29258248 PMCID: PMC5751009 DOI: 10.3390/ijerph14121592] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/05/2017] [Revised: 12/04/2017] [Accepted: 12/06/2017] [Indexed: 12/19/2022]
Abstract
Leishmania species are parasites that multiply within phagocytes and cause several clinical diseases characterized by single or multiple ulcerations. One of the complications that can induce tissue damage and the resulting scars is caused by secondary bacterial infections. Studies to find new, effective, and safe oral drugs for treating leishmaniasis are being conducted since several decades, owing to the problems associated with the use of antimonials available. Previously, the antiparasitic and antioxidant properties of Punica granatum (pomegranate, P. granatum) have been reported. Therefore, in the present study, we aimed to investigate the antileishmanial activity of pomegranate aqueous juice in vitro and in female BALB/c mice. A 3-(4.5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay in Leishmania major promastigotes and alterations in the antioxidant status, liver function, and skin histological changes in L. major-infected mice orally treated with pomegranate juice alone and in combination with the antibiotic ciprofloxacin, were used to investigate the in vitro and in vivo antileishmanial activity of pomegranate juice, respectively. Oral P. granatum juice treatment significantly reduced the average size of cutaneous leishmaniasis lesions compared with that of the untreated mice. This antileishmanial activity of P. granatum was associated with enhanced antioxidant enzyme activities. Histopathological evaluation proved the antileishmanial activity of P. granatum, but did not reveal changes in the treated animals, compared to the positive control. In conclusion, P. granatum shows high and fast antileishmanial activity probably by boosting the endogenous antioxidant activity.

Shahid F, Farooqui Z, Rizwan S, Abidi S, Parwez I, Khan F. Oral administration of Nigella sativa oil ameliorates the effect of cisplatin on brush border membrane enzymes, carbohydrate metabolism and antioxidant system in rat intestine. ACTA ACUST UNITED AC 2017; 69:299-306. [PMID: 28215571 DOI: 10.1016/j.etp.2017.02.001] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2016] [Revised: 01/30/2017] [Accepted: 02/07/2017] [Indexed: 12/25/2022]
Abstract
Cisplatin (CP) is an effective chemotherapeutic agent that induces gastrointestinal toxicity. Nigella sativa oil (NSO) has been shown to be beneficial in a wide range of gastrointestinal disorders. The present study investigates the possible protective effect of NSO on CP-induced gastrointestinal toxicity. NSO administration (2ml/kg bwt, orally), prior to and following, a single dose CP treatment (6mg/kg bwt. ip), significantly attenuated the CP-induced decrease in brush border membrane (BBM) enzyme activities in intestinal homogenates and BBM vesicles (BBMV). NSO administration also mitigated CP induced alterations in the activities of carbohydrate metabolism enzymes and in the enzymatic and non-enzymatic antioxidant parameters in the intestine. The results suggest that NSO by empowering the endogenous antioxidant system improves intestinal redox and metabolic status and restores BBM integrity in CP treated rats. Histopathological studies supported the biochemical findings. Thus, NSO may help prevent the accompanying gastrointestinal dysfunction in CP chemotherapy.

Abstract
Sudan folklore medicine is characterized by a unique combination of Islamic, Arabic, and African cultures. In poor communities, traditional medicine has remained as the most reasonable source of treatment of several diseases and microbial infections. Although the traditional medicine is accepted in Sudan, to date there is no updated review available, which focuses on most effective and frequently used Sudanese medicinal plants. Thus, this review aims to summarize the published information on the ethnobotanical uses of medicinal plants from Sudan, preparation methods, phytochemistry, and ethnopharmacology. The collected data demonstrate that Sudanese medicinal plants have been reported to possess a wide range of traditional medicinal uses including different microbial infections, gastrointestinal disorders, malaria, diabetes, rheumatic pain, respiratory system disorders, jaundice, urinary system inflammations, wounds, cancer, and different microbial infections. In most cases, the pharmacological studies were in agreement with traditional uses. Moreover, several bioactive compounds such as flavonoids, saponins, alkaloids, steroids, terpenes, tannins, fatty acids, and essential oils have been identified as active constituents. Although this review demonstrates the importance of ethnomedicine medicines in the treatment of several diseases in Sudan, further researches to validate the therapeutic uses and safety of these plants through phytochemical screening, different biological activity assays, and toxicological studies are still needed.

Abstract
Sildenafil is the first phosphodiesterase-5 inhibitor used for the treatment of erectile dysfunction. However, recent studies have been suggesting an antitumor effect of sildenafil. The current study assessed the aforementioned activity of sildenafil in vivo and in vitro in solid-tumor-bearing mice and in a human cell line MCF-7, respectively. Moreover, we investigated the impact of sildenafil on cisplatin antitumor activity. The solid tumor was induced by inoculation of Ehrlich ascites carcinoma cells in female mice. The tumor-bearing mice were assigned randomly to control (saline), sildenafil (sildenafil 5 mg/kg/d, PO daily for 15 days), cisplatin (cisplatin 7.5 mg/kg, IP once on the 12th day of Ehrlich ascites carcinoma inoculation), and combination therapy (cisplatin and sildenafil) groups. The tumor volume was measured at the end of the treatment period along with the following parameters: angiogenin, vascular endothelial growth factor, tumor necrosis factor-α, Ki-67, caspase-3, DNA-flow cytometry analysis, and histopathological examination. The study results showed that sildenafil has significantly decreased the tumor volume by 30.4%, angiogenin and tumor necrosis factor-α contents, as well as vascular endothelial growth factor expression. Additionally, caspase-3 level significantly increased with sildenafil treatment, whereas Ki-67 expression failed to show any significant changes. Furthermore, the cell cycle analysis revealed that sildenafil was capable of improving the category of tumor activity from moderate to low proliferative. Sildenafil induced necrosis in the tumor. Moreover, the drug of interest showed cytotoxic activity against MCF-7 in vitro as well as potentiated cisplatin antitumor activity in vivo and in vitro. These findings shed light on the antitumor activity of sildenafil and its possible impact on potentiating the antitumor effect of conventional chemotherapeutic agents such as cisplatin. These effects might be related to antiangiogenic, antiproliferative, and apoptotic activities of sildenafil.

Abstract
Thymus mitochondria play a crucial role in immune function. This study identifies the novel protective role of N-Acetylglucosamine (NAG) in dexamethasone (DEX) induced mitochondrial perturbations in mice thymus. Mice were induced with DEX (5mg/kg) and treated with NAG i.p. (266μg/kg, 400μg/kg and 800μg/kg) for 14 days, Withanolide A (800μg/kg) has been used as positive control. Dose dependent treatment of NAG against DEX significantly restored the mitochondrial enzyme levels (ICDH, KDH, SDH and MDH) and elevated the mitochondrial glutathione antioxidants defense (GSH, SOD, GPX and GST) thus improving the ATP status which was confirmed by ultrastructural alterations in mitochondria and nucleus using TEM studies. Further histopathological studies also revealed that NAG attenuate DEX induced thymotoxicity. Finally, the study concludes that dose dependent treatment of NAG supports a potential role in preventing DEX induced thymotoxicity and NAG acts as a beneficial pharmacological intervention in the DEX induced thymic repercussions.

Abstract
Neem (Azadirachta indica) is a member of the Meliaceae family and its role as health-promoting effect is attributed because it is rich source of antioxidant. It has been widely used in Chinese, Ayurvedic, and Unani medicines worldwide especially in Indian Subcontinent in the treatment and prevention of various diseases. Earlier finding confirmed that neem and its constituents play role in the scavenging of free radical generation and prevention of disease pathogenesis. The studies based on animal model established that neem and its chief constituents play pivotal role in anticancer management through the modulation of various molecular pathways including p53, pTEN, NF-κB, PI3K/Akt, Bcl-2, and VEGF. It is considered as safe medicinal plants and modulates the numerous biological processes without any adverse effect. In this review, I summarize the role of Azadirachta indica in the prevention and treatment of diseases via the regulation of various biological and physiological pathways.

Azadirachta indica attenuates cisplatin-induced nephrotoxicity and oxidative stress. BIOMED RESEARCH INTERNATIONAL 2014; 2014:647131. [PMID: 25162019 PMCID: PMC4137610 DOI: 10.1155/2014/647131] [Citation(s) in RCA: 32] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/21/2014] [Revised: 06/25/2014] [Accepted: 06/26/2014] [Indexed: 12/14/2022]
Abstract
We investigated the effects of methanolic leaves extract of Azadirachta indica (MLEN, 500 mg/kg bwt) on cisplatin- (CP-) induced nephrotoxicity and oxidative stress in rats. CP (5 mg/kg bwt) was injected intraperitoneally and MLEN was given by gastric gavage for 5 days before or after CP injection. After 5 days of CP injection, CP-induced injury of the renal tissue was evidenced (i) as histopathological damage of the renal tissue, (ii) as increases in serum uric acid, urea, and creatinine, (iii) as increases in malondialdehyde (MDA) and nitric oxide (NO), (iv) as decreases in the level of glutathione and activities of superoxide dismutase, catalase, glutathione reductase, glutathione-S-transferase, and glutathione peroxidase, and (v) as increase in the expression of nuclear factor kappa B and apoptosis in kidney tissues. However, the oral administration of MLEN to CP-intoxicated rats for 5 days brought back MDA, NO production, and enzymatic and nonenzymatic antioxidants to near normalcy. Moreover, the histological observations evidenced that neem extract effectively rescues the kidney from CP-mediated oxidative damage. Furthermore, PCR results for caspase-3 and caspase-9 and Bax genes showed downregulation in MLEN treated groups. Therefore, Azadirachta indica can be considered a potential candidate for protection of nephrotoxicity induced by cisplatin.
