Aims: The present study assessed the antioxidant and hepatoprotective potentials of the methanolic leaf extract of Lasimorpha senegalensis – a medicinal plant used by the indigenous people of Nigeria to treat hepatitis and feverish conditions. Place and Duration of Study: The research work was conducted in the Department of Pharmacognosy and Environmental Medicine and Department of Plant Science and Biotechnology, both in the University of Nigeria, Nsukka, from May to August, 2019. Methodology: Phytochemical analyses and acute toxicity study of the sample followed standard procedures. In vitro antioxidant assay was by DPPH and H2O2 models. A total of 25 male Wistar albino rats (120 – 150 g) were grouped into five, each group with five animals. Hepatotoxicity was induced with carbontetrachloride (1 ml/kg). The treatment groups (3-5) received extract (200 and 400 mg/kg) and Silymarin (100 mg/kg). Endogenous antioxidants (superoxide dismutase, catalase, glutathione peroxidase), plasma malondialdehyde and liver enzymes (aspartate aminotransferase, alanine aminotransferase, alkaline phosphate) were determined after treatment. Results: The results showed the leaf extract had appreciable amounts of bioactive phytochemicals and free radical scavenging activity (IC50 of 0.52 mg/ml and 0.71 mg/ml for DPPH and H2O2 respectively) with no toxicity at 5000 mg/kg. The extract also elevated the endogenous antioxidants and significantly (p ≤ .05) reduced lipid peroxidase and liver enzymes. Conclusion: This report justifies the local use of this plant in the management of various diseases related to oxidative stress and liver damage.

Objective: The objective of this study was to determine if there were any harmful effects of monosodium glutamate (MSG) on the liver of Wistar albino rats chronically at three different doses, namely, low, mid, and high doses equivalent to human consumption doses in developing countries. Methods: The Wistar albino rats (n=24) were divided into four groups, namely control, Low dose MSG (180 mg/kg), Mid dose MSG (360 mg/kg), and High dose MSG (720 mg/kg). At the end of the experimental period (120 days), animal blood was collected retro-orbitally to analyze the liver enzymes such as aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), Total protein, Albumin, and Total Bilirubin in blood serum. Lipid profiles, namely, Triglycerides, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and Total cholesterol were subjected to analysis using blood serum. Results: Significant increase (p<0.05) in AST, ALT, ALP, and total bilirubin in serum of MSG induced low, mid, and high dose groups when compared to control group were recorded. There was a significant increase (p<0.05) in LDL, decrease in HDL, increase in total cholesterol and triglycerides of MSG-induced animal groups. Conclusion: The effects of MSG on serum liver enzymes and lipid profiles in this present animal study were not severely alarming even though the dosage was chronic which opens further discussion on the controversies revolving around MSG.

Background: Type 2 diabetes mellitus (DM) is a common chronic disease with increasing prevalence worldwide. Prolonged uncontrolled hyperglycemia, dyslipidemia are major risk factor for its complication like neuropathy. Since there is no definite treatment for diabetic neuropathy, this study aims to evaluate the effect of resveratrol on diabetic neuropathy in high fat diet with low dose streptozotocin induced type-2 DM model in wistar albino rats.Methods: First type 2 diabetic rat model was established. Wistar albino rats, fed with high-fat diet (HFD) rendered diabetic with streptozotocin, were divided into 6 groups, disease control (DC) treated with vehicle, standard control (SC) which received metformin, test groups treated with 5, 10, and 20 mg/kg b.w. of resveratrol and combination of half dose of metformin and resveratrol (10 mg/kg) (TC). A group of six normal animals served as normal control (NC), another six as HFD control. Fasting plasma glucose, lipid profile were measured one week after induction of diabetes. The animals were then treated orally for 2 weeks after which the same parameters were repeated. Behavioral biomarkers for neuropathy are measured in 4 weeks and 6 weeks of treatment. The in-vivo results were analyzed by one way ANOVA followed by Tukey’s multiple comparison test for biochemical parameters and Kruskal Wallis test followed by Dun’s multiple comparison test for behavioral biomarkers.Results: Increase in fasting plasma glucose (FPG), deranged lipid profile, increased neuropathy in DC compared to NC, HFD control while a significant decrease in FBG, improved pain behavior with SC, test groups (p<0.05) as compared to the DC group.Conclusions: Resveratrol prevents diabetic neuropathy.

TEG-Pc, a Zn(II) phthalocyanine tetra substituted in non-peripheral position by tetraethylene glycol chains, proved to have good efficiency during in vitro photodynamic experiments. Its in vivo phototoxic effects have been investigated in tumor-bearing Wistar albino rats at an enzymatic level. The evolution of different oxidative markers are reviewed 6 h after the treatment.

Metabolizing Enzyme

A study was made of the nature and specificity of the increase in biphenyl 2-hydroxylase activity after preincubation of liver microsomal preparations with various carcinogens in vitro. This enhancement of enzyme activity in vitro was investigated in mouse, hamster and rat, and although the rat appears to be atypical in the variation of the pattern of 2- and 4-hydroxylation with age, similar enhancements were detectable in each species examined. An increase in biphenyl 2-hydroxylase activity was apparent 2h after intraperitoneal administration of safrole or benzopyrene to mature Wistar albino rats and appeared to be similar in nature to that observed after preincubation of liver microsomal preparations with the same chemical in vitro. Investigation of other drug-metabolizing enzyme systems suggests that the enhancing effects of carcinogens in vitro are specific for biphenyl 2-hydroxylase. No correlation between the enhancement of biphenyl 2-hydroxylase and inhibtion of biphenyl 4-hydroxylase was apparent.
