AMELIORATIVE EFFECT OF NARINGENIN AGAINST ANTITUBERCULOSIS DRUGS INDUCED ALTERATIONS IN HEMATOLOGICAL PARAMETERS OF RATS

Objective: The aim of the present study was to evaluate the efficacy of naringenin against antituberculosis drugs (ATDs) induced alteration in hematological parameters in rats.Methods: Rats were administered with ATDs for 8 weeks (3 days/weeks) followed by naringenin at three different doses (10, 20, and 40 mg/kg) conjointly for 8 weeks (3 days/weeks) orally. After 8 weeks, animals were euthanized; blood was collected by retro-orbital sinus method for the analysis of hematological parameters.Results: The results of this study show decreased in red blood cells, hemoglobin, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, platelets, and eosinophils along with increase in the number of lymphocytes in ATDs induced rats. Treatment with naringenin encountered ATDs induced hematological parameter alteration which was evident by significant reversal in hematological indices toward control in dose-dependent manner.Conclusion: The present study concluded that ATDs exposure caused adverse effects in various blood components and conjoint treatment of naringenin reduced hematological alterations toward control due to antioxidant activity

EFFECT OF RUTIN AGAINST HIGH-FAT DIET AND ALCOHOL-INDUCED ALTERATIONS IN HEMATOLOGICAL VARIABLES OF RATS

Objectives: Alcohol abuse leads to several diseases and millions of death worldwide. High-fat diet (HFD) is major contributor of non-alcoholic liver diseases and obesity. Combined consumption of HFD and alcohol has deleterious effect on blood cells. This study was carried out to evaluate the protective effect of rutin against combined consumption of HFD and alcohol-induced hematological alterations.Methods: HFD 30% and ethanol 10% were administered for 4 weeks for induction of toxicity. Rutin (10, 20, and 40 mg/kg) and 50 mg/kg dose of silymarin were administered along with HFD and alcohol for 4 weeks.Results: Combined consumption of HFD and alcohol increased mean corpuscular volume, total leukocytes count, eosinophil and monocyte, and decreased hematocrit and platelets. Administration of rutin improved hematological variables altered by HFD and alcohol consumption.Conclusion: The present study concluded that administration of rutin may alleviate HFD and alcohol-induced hematological alterations by scavenging free radicals generation

Propolis modulates cellular biochemistry, antioxidants, cytokine profile, histological and ultra-morphological status against antituberculosis drugs induced hepatic injury

Objective: To evaluate hepatic injury induced by antituberculosis drugs (ATDs) when administered orally for 2, 4, 6 and 8 weeks and the therapeutic potential of propolis (bee hive product) against ATDs induced hepatic injury. Methods: The ATDs were administered for 8 weeks as well as propolis extract at three different doses (100, 200, 400 mg/kg) conjointly for 8 weeks in rats. Silymarin (50 mg/kg) was given as positive control. Animals were euthanized after 8 weeks; blood and liver samples were collected to perform various biochemicals, serological and histopathological and ultramorphological studies. Results: Significant increase (P < 0.05) in aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, triglyceride and cholesterol along with reduction in glucose and albumin level were noted after ATDs induced hepatic injury. Significant increase (P < 0.05) in lipid peroxidation, triglyceride, cholesterol and CYP2E1 activity; decline in reduced glutathione, catalase, superoxide dismutase, glutathione reductase, glutathione peroxidase, glucose-6-phosphatase dehydrogenase activity were observed after ATDs intoxication. Due to presence of a wide range of flavonoids and polyphenols in propolis extract, its administration reduced hepatic injury and maintained biochemical indices towards control. Histopathological and electron microscopic observations indicated hepatoprotective potential of propolis at cellular level whereas, TNF-α, IL-6 and IGF-1 confirmed therapeutic potential of propolis at molecular level. Conclusions: It can be concluded that propolis possess hepatoprotective potential against ATDs induced hepatic injury that may prove itself as a clinically useful natural product in management of drug induced liver injury

Ameliorative effect of Pergularia daemia (Forssk.) Chiov. leaves extract against anti-tuberculosis drugs induced liver injury in rats

Objective: To evaluate therapeutic potential of hydroethanolic extract of Pergularia daemia (P. daemia) against anti-tuberculosis drugs (ATDs) induced liver injury. Methods: Wistar albino rats were divided into seven groups of six animal in each. The ATDs and P. daemia extract (100, 200 and 400 mg/kg, p.o.) were conjointly administered for 8 weeks and various biochemical, histoarchitectural, ultrastructural studies were performed. Results: Administration of ATDs significantly increased aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, triglycerides, cholesterol, bilirubin and decreased glucose and albumin level. Increased lipid peroxidation and reduction in glutathione, superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase and glucose-6-phosphate dehydrogenase were found after ATDs exposure. Administration of P. daemia extract maintained serum biochemical indices as well as antioxidant status similar to control and diminished oxidative stress in dose dependent manner. Histological and ultra-structural observations substantiated biochemical findings. Conclusions: P. daemia has therapeutic potential against ATDs induced liver injury and may be of clinical significance after extensive studies
