RÉSUMÉ
Objective To explore the effects of CO2 pneumoperitoneum on pancreatic function in diabetic rabbits. Methods Forty-eight rabbits were divided into 4 groups: control group (the group of N0, n=4), the group of T0 (n=4), the group of T10 (n=20), and the group of T15 (n=20). The animal used in the groups of T0, T10 and T15 was diabetic rabbit, and the pressures of pneumoperitoneum of the three groups were 0 mm Hg, 10 mm Hg and 15 mm Hg respectively.The model of diabetic rabbits were made through intrvenous administration of Allxon. Arterial blood samples were collected before the onset of CO2 pneumoperitoneum, 0, 2, 6, 12 hours after deflation for measuring blood glucose, amylase, insulin and C-peptid. Then the rabbits were sacrificed and their pancreases were removed for measuring SOD activity and MDA content. Results After abdominal deflation, the blood glucose, amylase, insulin, C-peptid, MDA content were significantly increased (P
