Aim: To evaluate the effects of alcohol on the microscopic morphology of the exocrine pancreas and blood serum amylase and to explored that if vitamin E has a protective role against alcohol-induced damage in the pancreas of rabbits. Study design: Analytical experimental study Place and duration of study: Departments of Anatomy, Pathology and Pharmacology in Peshawar Medical College Pakistan from 1st January 2019 to 30th June 2019. Methodology: Eighteen healthy adult male domestic rabbits weighing 1-1.5 kg were chosen (oryctolaguscuniculus). The control group A received proper food and normal saline as drinking water, experimental group B received proper diet and 30 percent ethanol solution (30ml/kg/day) orally daily with normal saline, and experimental group C received proper diet, 30 percent ethanol solution (30ml/kg/day), vitamin E (50mg/kg/day) orally daily with normal saline. Each rabbit's blood was taken for serum amylase. Morphology of acinar cells included: 1) number of cells, (10 acini/field, 2) size of acini, 3) size of acinar cells, and 4) size of acinar nuclei. Results: Normal value of serum amylase in rabbits was found. The difference in serum amylase levels between the control and experimental groups for both E4 and E8 animals was not statistically significant. There was no significant difference in the number of pancreatic acinar cells, size of pancreatic acini, the pancreatic acinar cell size, and pancreatic acinar cells nuclear size in the control and experimental groups for both E4 and E8 animals. Conclusion: Alcohol consumption had no influence on the histomorphology of the rabbits' pancreatic acini in a short period (4-8 weeks). No significant variation was noted in the pancreatic acinar cells count & size, pancreatic acinar cells nuclear count and size, and pancreatic acini size. Therefore, protective role of vitamin E was not usefully identified. Keywords: Alcohol, Pancreas, Histomorphology, Vitamin E, Serum amylase
Background: Alcohol induces histomorphological changes in the liver and vitamin E has a protective role against these changes. Objective: To observe changes in hepatocytes of rabbits exposed to intragastric administration of alcohol and the protective role of vitamin E against these changes. Study Design: Analytical experimental study Place and Duration of Study: Department of Anatomy, Pathology and Pharmacology of Peshawar Medical College, Peshawar, Pakistan from 1st January 2016 to 30th June 2016. Methodology: Eighteen male rabbits domestic type (Oryctolaguscuniculus) were included. Experimental duration for category E8 animals was 8 weeks while for category E4 animals it was 4 weeks. The groups were, control group A in which animals were given proper food and normal saline as drinking water, experimental group B in which animals were fed on proper diet and 30% ethanol solution (30 ml/kg/day) orally daily with normal saline and experimental group C in which animals were treated with proper diet, 30% ethanol solution (30 ml/kg/day), vitamin E (50 mg/kg/day) orally daily and normal saline as drinking water. Results: The difference in the ALT, hepatocyte count and size and hepatocyte nuclear count and size of control and experimental groups and experimental group B-II and C-II from both category E4 and E8 showed a highly significant P values. Conclusion: Alcohol causes histomorphological changes in the liver even in the short period of 4-8 weeks and these changes can be minimized by the antioxidant action of vitamin E.
