AIM: To study the effects of Radix Puerariae flavones (RPF) on liver lipid metabolism in ovariectomized (OVX) rats. METHODS: Forty adult female Wistar rats were randomly divided into four groups: OVX group; sham-OVX group; OVX+estrogen group and OVX+RPF group. One week after operation rats of the first two groups were treated with physiological saline, rats of OVX+estrogen group with estrogen (1 mg/kg.b.w.) and rats of OVX+RPF group with RPF (100 mg/kg.b.w.), respectively for 5 weeks. After the rats were killed, their body weight, the weight of the abdominal fat and uterus were measured, and the levels of total cholesterol (TC) and triglyceride (TG) in liver homogenate were determined. RESULTS: Compared with the sham-OVX group, the body mass of the rats in OVX group was found increased significantly; more abdominal fat in store; TC and TG in liver increased and uterine became further atrophy. As a result, the RPF was found to have an inhibitive action on those changes of various degrees. CONCLUSION: RPF has estrogen-like effect on lipid metabolism in liver and adipose tissue.
AIM: To study the effects of glutamine (Gln) on the change of intestinal permeability and its relationship to systemic inflammatory response in early abdominal postoperative patients. METHODS: A prospective, randomized, double-blind and controlled trial was taken. Twenty patients undergoing abdominal surgery were randomized into Gln group (oral administration of glutamine, 30 g/d, for 7 d, n=10) and placebo group (oral administration of placebo, 30 g/d, for 7 d, n=10). Temperatures and heart rates of all patients were daily recorded. White blood cell counts(WBC) and biochemical variables were measured before operation and 4 and 7 d after drug administration. Serum concentrations of glutamine, endotoxin, diamine oxidase and malondialdehyde and urine lactulose/mannito (L/M) ratio were measured before and 7 d after drug administration. RESULTS: The patients in the 2 groups were comparable prior to drug administration. Serum Gln concentration was significantly decreased in the placebo group and increased in the Gln group 7 d after drug administration. Urine L/M ratio was significantly increased in the placebo group and decreased in the Gln group. The serum concentration of endotoxin, diamine oxidase and malondialdehyde was significantly decreased in the Gln group compared with those in the placebo group. Temperatures, heart rates and WBC counts were significantly lower in the Gln group than those in the placebo group. CONCLUSION: Gut is one of the sources of systemic inflammatory response in abdominal postoperative patients and glutamine can decrease intestinal permeability, maintain intestinal barrier and attenuate systemic inflammatory response in early postoperative patients.
