• AIM：To study the effect of salvianolate on expression of tumor necrosis factor （TNF）-α and interleukin （IL）-6 mRNA in small intestine of cirrhotic rats. METHODS：Cirrhosis in rats was induced using CCl4 （0.3 mL/kg）. Rats were randomly divided into non-treatment group,low-dose salvianolate （12 mg/kg） treatment group,medium-dose salvianolate （24 mg/kg） treatment group,and high-dose salvianolate （48 mg/kg） treatment group,and treated for 2 wk. Another 10 healthy rats served as a normal control group. Mortality of cirrhotic rats in each group was evaluated after treatment with salvianolate. Serum samples were taken from portal vein for the detection of endotoxin. Morphological changes in tissue samples from the ileocecum were observed under a light microscope. Expression of TNF-α and IL-6 mRNA in the small intestine of rats was analyzed by real-time reverse-transcriptase polymerase chain reaction. RESULTS：The mortality of cirrhotic rats in the nontreatment group was 37.5%. No cirrhotic rat died in the high-dose salvianolate treatment group. The serum endotoxin level was significantly higher in the non-treatment group than in the salvianolate treatment and normal control groups. The intestinal mucosal and villous atrophy,necrosis and shedding of the intestinal mucosal epithelium,observed in the non-treatment group,were reversed in different salvianolate treatment groups. The TNF-α and IL-6 mRNA expression levels in small intestine were significantly lower in different salvianolate treatment groups than in the non-treatment group. CONCLUSION：Salvianolate can reduce the endotoxin level,ameliorate the injury of intestinal mucosa,and inhibit the expression of TNF-α and IL-6 mRNA in small intestine of cirrhotic rats.
