摘      要：BACKGROUND Aloe vera exerts several biological activities,such as,anti-inflammatory,antioxidant,and antimicrobial *** was recently shown to reduce insulin resistance and triglyceride *** hypothesized that aloe vera would have beneficial effects in alleviating non-alcoholic steatohepatitis(NASH)in *** To examine the therapeutic effects of aloe vera in NASH *** All rats were randomly divided into 3 groups(n=6 in each group).Rats in the control group were fed ad libitum with a standard diet for 8 *** in the NASH group were fed ad libitum with a high-fat high-fructose diet(HFHFD)for 8 *** in the aloe vera group were fed ad libitum with a HFHFD and aloe vera in dimethylsulfoxide(50 mg/kg)by gavage daily for 8 *** samples were collected at the end of the treatment *** Hepatic malondialdehyde(MDA)levels increased significantly in the NASH group as compared with the control group(377±77 nmol/mg vs 129±51 nmol/mg protein,respectively,P0.001).Glutathione(GSH)levels were significantly lower in the NASH group than the control group(9±2 nmol/mg vs 24±8 nmol/mg protein,respectively,P=0.001).The expression of interleukin-18 (IL-18), nuclear factor-kappa β, and caspase-3 increased, while peroxisomeproliferator-activated receptor gamma decreased in the NASH group comparedwith the controls. Following aloe vera administration, MDA levels decreased (199± 35 nmol/mg protein) and GSH increased (18 ± 4 nmol/mg protein) ***, hepatocyte ballooning, lobular inflammation and increased hepatocyteapoptosis were observed in the NASH group. Aloe vera treatment attenuatedthese changes in liver *** vera attenuated oxidative stress, hepatic inflammation and hepatocyteapoptosis, thus improving liver pathology in rats with NASH.
