RESUMEN
Objective To observe and compare the functions of two types microencapsulated adult pig pancreatic islets in vivo.Methods The diabetic rats induced by streptozocin were divided into four groups:control group,non-encapsulated islet transplantation group,encapsulated islet with sodium alginate membrane transplantation group and encapsulated islet with agarose membrane transplantation group.All rats received intraperitoneal of islet transplantation.Results There were no significant difference in mean level of the blood glucose before transplantation among four groups.On the 7th day after transplantation,the mean level of the blood glucose in four groups were (22 67?1 15)mmol/L,(18 58?2 66)mmol/L(12 27?1 36)mmol/L and (12 38?2 68) mmol/L,respectively.There were significant difference between two encapsulated islet groups as compared with the other two groups(P
