Protective effects of sulforaphane and aerobic exercise on acute alcoholic hepatic injury in mice

OBJECTIVE: The paper intends to study the protective effects of sulforaphane (SF) on acute alcoholic hepatic injury in mice by intragastric administration of SF, aerobic exercise and the approach of SF integrated with aerobic exercise. METHODOLOGY: 60 NIH mice were randomly divided into 6 groups of equal number according to their body weight and were intragastrically administrated with 50% ethanol. The serum and liver indexes of each group of mice were detected, and the liver was stained with oil red O for pathological examination. RESULTS: Compared with the model group, the serum TG and the ratio of liver to body weight of the model mice that suffered from acute alcoholic hepatic injury could be significantly decreased in the group that practiced aerobic exercise, the group administered with SF, and the group treated with the approach of SF integrated with aerobic exercise (P < 0.05). The contents of TG and MDA in liver could be significantly decreased (P < 0.05) and SOD activity could be significantly increased (P < 0.05) both in the group administered with SF and the group treated with the approach of SF integrated with aerobic exercise. Serum VLDL (P < 0.05) could also be significantly reduced in the group treated with the approach of SF integrated with aerobic exercise. CONCLUSION: Both SF and aerobic exercise could alleviate alcohol-induced acute alcoholic hepatic injury in mice possibly thanks to the working mechanism related to antioxidant stress that reduced the harm posed by alcohol on hepatic cells. In addition, the protective effect of SF on acute alcoholic hepatic injury in mice was stronger than that of aerobic exercise, while the approach of SF integrated with aerobic exercise had the strongest protective effect on acute alcoholic hepatic injury in mice.
