    Abstract:
    Pancreatic regeneration after pancreatectomy has been well documented in the animal models. We have recently reported that STZ diabetic animals operated for partial pancreatectomy showed normoglycemic status after the operation as compared to uncontrolled hyperglycemia and even death in the diabetic sham operated animals. In drug and virus-induced experimental diabetic models there is a high mortality of animals due to uncontrolled destruction of the beta-cells. In order to destroy sufficient beta-cell mass so as to induce diabetes but prevent mortality, we designed present studies to investigate the combined effect of pancreatectomy, nicotinamide, and streptozotocin (STZ) on diabetic status of BALB/c mice. BALB/c mice of either sex were subjected to 50% pancreatectomy. These were then treated with nicotinamide (350 mg/kg body weight) before and after streptozotocin (200 mg/kg body weight) administration. The changes in body weight, blood glucose levels, serum and pancreatic insulin contents of these animals were monitored in experimental and control group for 12 weeks, and follow up studies were made of these animals for further 12 weeks. It was found that there was a drastic loss of body weight, decreased serum and pancreatic insulin levels coupled with sustained and low levels of hyperglycemia in the experimental group as opposed to the control group. The results indicate that partial pancreatectomy followed by nicotinamide and streptozotocin treatment leads to a long-lasting hyperglycemic state, depicting the clinical symptom of NIDDM without mortality. The study probably reveals a new model for experimental diabetes.
