ABSTRACT
The study designed to evaluated the activity of pancreatic exocrine enzymes in diabetic male rats induced by alloxan. The hyperglycaemia was induced in forty-five rats after fasting of the animals for 24 hours by single intraperitoneal (i.p) injection of Alloxan100mg/kg B.W., three days after injection fasting blood glucose was measured when the concentration higher than 150mg/dL, were considered as hyperglycemic/ diabetes. A total of sixty adult male rats (45 diabetes and 15 non- diabetes) divided in to two groups as follows. The first group serves as control groups (15 animals) will be single i.p injection with distilled water. the second group diabetic groups (45 animals from first experiment) were subdivided into three subgroups as following (15 for each). Group (G1), Group (G2) and Group (G3) serves as 20, 40- and 60-days diabetic animals respectively. The blood samples collection were take through cardiac puncture technique from each rat for each period days for measurement the following parameters (Serum glucose, total protein, insulin, cholesterol, albumin, triglyceride, LDL-C, HDL-C and VLDL-C) concentration, the rats pancreatic tissue were be taken for measured tissue pancreatic lipase, amylase, and trypsin concentration. The results demonstrate a significant increase in serum glucose concentration and a decrease in serum insulin and total protein in the diabetic group as compared with the control rats' group in all experimental days. The results showed a significant rise in serum total cholesterol concentration within the diabetic group when compared with the control group at day 20 and 60. Meanwhile, a significant increase in serum triglyceride and LDL concentration and a significant decrease in serum HDL concentration within the diabetic group when compared with the control rats group at day 20, 40 and 60. But the serum VLDL concentration depicted a significant increase in the group of diabetic when compared with the control rats group at day 40 and 60. The value of pancreatic tissue protease activity clarified there was a significant decrease of protease action in the group of diabetic rats when compared with the control rats group on both day 20 and day 60. And a significant decrease in amylase activity in the diabetic groups when compared with the group of control rats in both day 20, 40 and day 60. While the results of pancreatic tissue lipase show there were non-significant changes within the diabetics group when compared with the control group. In conclusion, the exocrine pancreatic function is very frequently and severely altered in diabetes mellitus male rats and the metabolic disorder effect of diabetes mellitus was manifested by hyperlipidemic and hypoprotenimic .
