Hepatoprotective effect of some drugs in experimental model of acute liver injury

ABSTRACT

Acute liver injury is a clinical condition that results from severe extensive damage of liver tissue associated with Jaundice and it is experimentally induced by hepatotoxic agents like ccl[4]. Thirty five healthy rabbits were involved in the present study. They were allocated to five groups. Each group was given one of the following agents vitamin E, zinc sulfate, amlodipine besylate, distilled water two hours before administration of ccl[4]. The same doses of the tested agents were continued for two days after ccl[4] administration. The effect of drugs was evaluated at two occasions 24 and 72 hours after ALI induction on the basis of biochemical analysis of liver function tests as well as histopathological examination to the liver of treated animals. All the tested agents produced significant reduction in ALT, AST, ALP, and TSB with a significant elevation of TSP levels as compared with treated control group. The histopathological examination showed clear improvements in the sections of liver tissue that support the effect of these agents on the liver. The study showed that 30% of women were anemic; the effect of anemia on thyroid function was not clear as 98% of the studied women have normal thyroxin and only 1% has low thyroxin level while 1% showed high concentration of thyroxin level. All the tested agents proved to have hepatoprotective effect of varying degree on ALI model
