Abstract
The current study aimed to evaluate the probable protective effect of Lepidium sativum seeds (LSS) against CCl4 induced hepatic injury in New-Zealand rabbits. Rabbits were randomly divided into two main groups; group-A (noninjured group, n=15) was divided to subgroups A1 (untreated control) and A2 and A3 which received 200 & 400 mg/kgbw of LSS, respectively, in their diet daily. Group-B (injured group, n=30) were subcutaneously injected with CCl4 (0.5 ml/kgbw) starting from day one of the experiment and were equally divided into 3 subgroups: B1 received normal standard diet and B2 & B3 received 200 & 400 mg/kgbw of LSS, respectively, in their diet daily. Five rabbits of all subgroups were decapitated 5 and 10 weeks after experimental running. Biochemical analysis revealed significant decrease in serum levels of transaminases, -GT, ALP, total bilirubin, cholesterol, triglycerides associated with significant increase in the serum levels of T protein and albumin of 200 and 400 mg/kgbw of LSS protected rabbits for 5 and 10 weeks as compared with CCl4 treated rabbits. Oxidative stress and depressed antioxidant system of the liver tissues were markedly obvious in the CCl4 treated group. LSS administration reversed these results towards normalization. Histopathological examination of LSS protected rabbits (200 mg/kgbw of LSS for 10 weeks) showed improvement of the histoarchitectural changes of the liver induced by CCl4 to the normal aspect, showing regenerating hepatocytes with no steatosis, discrete chronic venous congestion, and discrete inflammatory infiltrate. The current findings provide new evidence that LSS could reverse the hepatotoxic effects of CCl4 and repair the liver functions.
