چکیده انگلیسی
In this study, the water-soluble selenium-enriched exopolysaccharides (Se-ECZ-EPS) were isolated from submerged culture broth of Enterobacter cloacae Z0206 through fermentation, ethanol precipitation and deproteinization. The protective effects of Se-ECZ-EPS on alloxan-induced diabetic mice were investigated. Diabetes was induced in ICR (Institute of Cancer Research) mice by administration of single doses of alloxan intraperitoneally (190Â mg/kg body weight). Se-ECZ-EPS at a dose of 200Â mg/kg body weight were administered per os (p.o.) as single dose per day to diabetes-induced mice for a period of 42 days. The decrease in body weight, serum insulin level, and the increase in blood glucose level, glycosylated serum protein (GSP), total cholesterol (TC) and triglycerides (TG) in liver were observed in diabetic mice. On the other hand, oral administration of Se-ECZ-EPS resulted in a significant reduction in fasting blood glucose levels, GSP, TC and TG contents in liver coupled with improvement of body weight and serum insulin level in comparison with diabetic control group. These results suggest that Se-ECZ-EPS possess significant protective and anti-diabetic effects in alloxan-induced diabetic mice.
