Oxidative stress mediated hepatotoxicity induced by ZNP and modulatory role of fruit extract on male Wistar rat.

ABSTRACT: Zinc oxide nanoparticles (ZNP) are being used in various fields viz cosmetics industry as UV protectants, in the food packaging industry due to their anti-bacterial properties, in agriculture as micronutrients, etc. Increased applications of ZNPs in our day to day life, leading to the contamination of the surrounding environment posing a direct or indirect health risk. Various reports suggest that fruits and vegetables are a rich source of phytochemicals having antioxidant properties which help in neutralizing ROS generated on metal toxicity of the body. The present study focuses to study the ameliorative effect of apple (Pyrus malus) extract (E) on ZNP induced toxicity. Therefore, animals were grouped, six in each, exposed to various doses of ZNP (50 and 250 mg/kg), ZNP (50 and 250 mg/kg)+E. The studied parameters was: food intake, water intake, antioxidants assay, zinc accumulation, and histological alterations and was compared to control. Investigation revealed that ZNP induces toxicity as revealed by the alteration in the studied parameter, whereas those exposed to ZNP along with Pyrus malus fruit extract try to reduce the toxicity induced by nanoparticles but at low doses only. This ameliorative effect of fruit extract might be due to the presence of antioxidants scavenging the free radicals generated by ZNPs suggesting that antioxidant-rich fruit may have a protective role and have the potential to reduce the nanoparticles mediated oxidative stress.

Project description:Introduction: Diabetes Mellitus is a major health problem characterized by hyperglycemia and disturbances in metabolism and implicated in causing oxidative stress. Treatment includes administration of oral hypoglycaemic agents with lifestyle modifications, these offer glycemic control, however, present limitations about availability, affordability and side effects. Traditional anti-diabetic plants are becoming popular in management of diabetes mellitus. This study was carried out to determine the efficacy of Leptadenaia hastata in treatment of diabetes.Materials and methodsDiabetes mellitus was induced in using a single injection of streptozotocin (50 mg kg- 1 i.p.). The rats were divided into four groups of 5 rats each. Groups 3-6 received olive oil, 100 mg kg- 1 extract, 200 mg.kg- 1 extract and insulin (6IU kg- 1), respectively. 10 non-diabetic rats were grouped into two group receiving olive oil and 200 mg kg- 1 extract for 28 days. All groups were sacrificed by injecting with ketamine hydrochloride, blood was collected by cardiac puncture and centrifuged. The serum was analyzed for biochemical parameters. The liver was removed and homogenized with the supernatant of the resultant homogenate collected and used for analysis of oxidative stress enzymes.ResultsThe extract significantly decreased serum AST (p < 0.05), ALP (p < 0.001), ALT (p < 0.05), TG (p < 0.01), TC (p < 0.001), creatinine (p < 0.001). It had no effect on SOD and CAT levels but it significantly increased (p < 0.001) GSH levels and reduced (p < 0.05) MDA level.ConclusionsThe n-hexane extract of Leptadenia hastata significantly decreased the levels of hepatic and renal serum biomarkers proving that it was beneficial in ameliorating diabetic related complications. The extract significantly increased GSH levels and reduced MDA level.Supplementary informationThe online version contains supplementary material available at 10.1007/s40200-022-01017-z.
