BACKGROUND: The purpose of this study was to investigate the hypoglycemic effect of new biliopancreatic diversion and duodenal-jejunal bypass in Goto-Kakizaki rats and observe effects of the new surgical procedure on the glucose tolerance of GK rats. METHODS: Twenty-four 10-week-old rats (SPF grade) were randomly divided into groups A, B, and C, each with eight rats. Group A underwent duodenal-jejunal bypass, group B underwent modified biliopancreatic diversion, and group C underwent a sham operation. Median rat body weight, fasting blood glucose, OGTT, and blood lipids were measured in fasting 1 week before surgery and 1, 2, 4, and 8 weeks after surgery. Changes in gastric inhibitory polypeptide, glucagon P-like peptide-1, and insulin levels were measured by ELISA 1 week before surgery and 8 weeks after surgery. RESULTS: Rats' mean body weight in groups A and B decreased significantly from 368.025 ± 11.726 and 373.100 ± 9.859 g preoperatively to 345.750 ± 11.403 and 343.260 ± 12.399 g at the early postoperative stage (P < 0.05), and with statistically significant differences compared to the weight of rats in group C (P < 0.05). Comparisons between fasting blood glucose before surgery and 8 weeks after surgery revealed no significant differences between all three groups (P > 0.05). Glucose tolerance in groups A and B decreased from preoperative 21.175 ± 3.684 and 20.820 ± 1.671 mmol/L to postoperative 8.950 ± 0.580 and 10.500 ± 1.509 mmol/L, and both were better than that of group C (P < 0.001). CONCLUSIONS: Both new biliopancreatic diversion and duodenal-jejunal bypass improve glucose tolerance of Goto-Kakizaki rats. |
