Abstract:
Objective: to observe the effect of Roux-en-Y Gastric Bypass (RYGB)on STZ induced type 2 diabetic rat model, and to clarify its initial mechanism. Methods: 42 type 2 diabeticrats were randomly allocated into operation group(group O 12 rats); sham group(group S 10 rats); diet control group(group F 10 rats); control group(group C 10 rats). Fasting glucose, Insulin Growth Factor-1 ( IGF1), fasting plasma insulin levels, weight and food intake were measured before and 1st , 2nd, 3 rd ,4th, 8th and 16 th week after operation. Results: 16 weeks after operation in the Group O, fasting glucose fell to (8.8?4.9)mmol/L, IGF1 increase to (148.6?7.3)ng/L ,fasting plasma increase to (74.7?9.2)mIU/L and weight decline to (212.6?15.1)g ,there was statistical significance compared with the levels of preoperation (P
