|Abstract:||Isotretinoin is an analogue of vitamin A and by suppressing the sebaceous glands it is often prescribed in cases of severe acne treatment. The treatment for the average patient is carried out during two to ten months. This study was designed to investigate liver structure, hepatic enzyme levels and the stress oxidative parameter after isotretinoin treatment during a similar period and using the dosages of 1 mg/kg and another one of 10 mg/kg in young male Wistar rats. We have analyzed the blood serum biochemical levels to determine hepatic function and lipid peroxidation, hepatic tissue levels of hepatic enzymes, histology and ultrastructure. The groups receiving 1 mg/kg were not altered after treatment. Their ultrastructure showed a metabolically more active organ after treatment with 10 mg/kg, in which there was an increase in the area occupied by mitochondria and rough reticulum in electron transmission images. The group that received 10 mg/kg also showed increased alkaline phosphatase, decreased high density lipoprotein and low density lipoprotein. The changes observed with the 10 mg/kg dose were not conclusive for liver damage, because of the lack of histological structural modifications and the few biochemical alterations. The 1 mg/kg dose showed a liver responding to some stimuli but without profound alterations. So, we confirm that the proposed protocol with 1 mg/kg or 10 mg/kg isotretinoin did not cause important biochemical and histological disfunctions for male Wistar rat livers|
