Attenuation of hepatotoxicity and oxidative stress in diabetes STZ-induced type 1 by biotin in swiss albino mice

Abstract EN

Diabetes mellitus is one of the major health problems.

This study was designed to investigate the effect of biotin to regulate blood glucose level, reduced toxicity and oxidative stress in liver of diabetic mice STZ-induced type 1.

Male mice were divided into three groups, the first one served as the control group, the second and the third groups received single ip dose of 150 mg/kg of STZ, the second group served as the untreated diabetic group, the third group received daily oral dose of 15 mg/kg of biotin, livers and liver index showed insignificant difference among groups.

Blood glucose level showed a significant decrease in treated diabetic mice compared to untreated diabetic mice.

Biochemical analysis showed a significant decrease in liver enzymes AST and ALT compared to the control group.

Histopathological examination showed severe changes in untreated diabetic liver tissue manifested by dilated portal vein, leukocytic infiltration, fatty degeneration and moderate to severe histopathological score, whereas, treated diabetic mice with biotin showed reduction in hepatotoxicity represented by appearance of relative healthy hepatocytes and normal histopathological score.

Immunohistochemistry of acrolein showed intense immunoreactions in liver section of untreated diabetic mice and faint immunoreactions in treated diabetic mice with biotin as evidence to oxidative stress reduction
