THE EFFECTS OF ROMARINUS OFFICINALIS LEAF HYDROALCOHOLIC EXTRACT ON HISTOPATHOLOGY AND ENZYMES ACTIVITY OF LIVER IN ALLOXAN INDUCED DIABETIC RATS

Background: Diabetes produces free radicals and damages the liver. The aim of this study was to investigate the effects of Rosmarinus Officinalis leaf hydroalcoholic extract on histopathology and enzymes activity of liver in alloxan induced diabetic rats. Methods: In this study, 50 adult male Wistar rats weighing 200 to 250 grams, were divided randomly into 5 groups of 10; non-diabetic control, diabetic control and 3 experimental groups (diabetic rats treated with the dosage of 50mg/kg, 100mg/kg and 200mg/kg rosemary leaf extract intraperitoneally for 14 days). Diabetes was induced in rats by intraperitoneal injection of a single dose 120 mg/kg alloxan was done. At the end of the treatment period, blood samples were taken from the left ventricular heart of mice and aspartate aminotransferase (AST / SGOT), alanine aminotransferase (ALT / SGPT) and alkaline phosphatase (ALP) in serum were measured. Immediately liver was removed and histological samples were fixed in 10% formalin and then stained with hematoxylin-eosin technique (H & E). Results: In diabetic rats, unlike control mice, the liver enzymes (AST, ALT and ALP) increases, because of damage of liver tissue (p<0.01). The level of liver enzymes (AST, ALT and ALP) in rats treated with doses 50mg/kg, 100mg/kg and 200mg/kg of rosemary leaf extract showed a significant reduction in these enzymes compared to control diabetes (p<0.01). Conclusion: Histological studies showed reduced inflammation in the liver lobule and the port in the experimental groups. The third experimental group had greatest impact on reducing liver inflammation and space ports showed lobule. Histologically, tissue changes were in line with biochemical changes. The effects of Rosmarinus Officinalis leaf hydroalcoholic extract because of its high antioxidant properties, reduce free radicals and inflammation of the liver damage caused by diabetes by inhibiting the enzyme is reduced.
