ANTI-PARKINSON ACTIVITY OF AQUEOUS EXTRACT OF LEAVES OF MURRAYA KOENIGII AGAINST PARAQUAT-INDUCED PARKINSONISM IN WISTAR RATS

Objective: The current study evaluates anti-Parkinson’s activity of aqueous extracts of leaves of Murraya koenigii (MK) (AEMK) against paraquat (PQ)-induced Parkinsonism in rats. Methods: In this study, effects of MK (100, 200, and 400 mg/kg, p.o.) were studied using in vivo behavioral parameters such as catalepsy, muscle rigidity, and locomotor activity and its effects on neurochemical parameters malondialdehyde, catalase (CAT), glutathione (GSH) reductase, GSH peroxidase, and GSH in rats. Results: Parkinson’s disease was induced by administering PQ 10 mg/kg b.w/i.p once in a week for 4 weeks. The increased cataleptic scores were significantly (p<0.001) found to be reduced, with the AEMK in a dose-dependent manner. Chronic administration of PQ significantly induced motor dysfunction (muscle rigidity and hypolocomotion), showed a significant increase in lipid peroxidation level, and depleted the levels of GSH, CAT, and reduced GSH. Daily administration of AEMK significantly improved motor performance and also significantly attenuated oxidative damage. Conclusion: The study proved that MK treatment significantly attenuated motor defects and also protected the brain from oxidative stress

PROTECTIVE EFFECT OF AQUEOUS EXTRACT OF LEAVES OF MURRAYA KOENIGII, AGAINST ALUMINUM CHLORIDE-INDUCED OXIDATIVE STRESS IN RAT LIVER AND KIDNEY

Objective: The aim of the current study was to investigate the hepatoprotective, nephroprotective, and cholesterol-lowering activity of aqueous extract of Murraya koenigii (MK) leaves against AlCl3-induced oxidative stress in rats. Methods: Wistar albino rats were distributed into six groups (6 each). Group I (control), and Group II administered with distilled water, and aluminum chloride (AlCl3), (40 mg/kg body weight [b.w], oral), respectively. Group III rats were treated with standard Vitamin E (100 mg/kg b.w, p.o) and AlCl3 (40 mg/kg b.w, oral). Group IV, V, and VI received aqueous extract of leaves of Murraya koenigii (AEMK) (100 mg/kg b.w, peroral [p.o], 200 mg/kg b.w, p.o, and 400 mg/kg b.w, p.o), respectively, for a period of 35 days. Results: Histopathological examination was observed deformities in hepatic and renal tissues due to aluminum exposure which augment the aforementioned results. Coadministration of AEMK along with Al significantly restored the serum biomarkers to their near-normal levels and has the ability to overcome Al-induced oxidative stress, manifested by a significant reduction in hepatic and renal malondialdehyde level. It increased cellular antioxidant defense, particularly by increasing GPx, glutathione, GR, and catalase levels, preserved normal hepatic and renal histological architecture. Conclusion: It could be concluded that AEMK has significant radical scavenging activity and can mop up Al-induced toxicity, suggesting hepatoprotective and nephroprotective potential

Hepatoprotective activity of Lagenaria siceraria fruit extracts against carbontetrachloride-induced hepatic damage in rats

ABSTRACT Evaluation of the hepatoprotective activity of Lagenaria siceraria fruit extracts against carbontetrachloride (CCl4)-induced hepatotoxicity was done on rats. Hepatotoxicity was induced in male Wistar rats by intraperitoneal injection of CCl 4 (1 ml/kg/day for 7 days). Lagenaria siceraria ethanol extract (LSEE) and vacuum dried Lagenaria siceraria juice extract (LSJE) were administered to the experimental rats (400 mg/kg/day, p.o. for 10 days). The hepatoprotective effect of these extracts was evaluated by the assay of liver function biochemical parameters (total bilirubin, serum protein, alanine aminotransaminase, aspartate aminotransaminase, and alkaline phosphatase activities), liver weight and histopathological studies of the liver. In LSEE-treated animals, the toxic effect of CCl 4 was controlled significantly by restoration of the levels of serum bilirubin, protein and enzymes as compared to the normal and the standard drug silymarin-treated groups. Histology of the liver sections of the animals treated with the extracts showed the presence of normal hepatic cords, absence of necrosis and fatty infiltration, which further evidenced the hepatoprotective activity. In conclusion LSEE and LSJE possess significant hepatoprotective activity
