Abstract
This study was done to show the changes in the liver following diclofenac treatment and to study the hepatoprotective effects of Vitamin E and A in diclofenac treated rats. Rats were divided into four groups of six rats each. Group-1: Control rats (n= 6), Group-2: Rats (n= 6) treated with diclofenac at dose of 50 mg/kg IM for 7 days, Group-3: Rats (n= 6) treated with Vitamin A at dose of 400 IU/kg orally followed by diclofenac at 50 mg/kg IM 2 h later for 7 days, and Group 4: Rats (n= 6) treated with Vitamin E at dose of 200 IU/kg orally followed by diclofenac at 50 mg/kg IM 2 h later for 7 days. Later it was analysed with standard bio markers, and it was histologically interpreted. The results showed that there was an rapid increase in the levels of liver function test in diclofenac-treated group, which was significantly decreased after pre-treatment with vitamin E than vitamin A. The liver acinus showed centriacinar necrosis of hepatocytes after 7 days of diclofenac treatment, which was prevented by administration of Vitamin E and A. Drug-induced liver injury possesses a major clinical problem and has become a leading cause of acute liver failure and transplantation.
