Biochemical and Histopathological study Of The Proteinaceous Compounds Separated From Aqueous Extract Of Marus Albul L. Fruit in alloxan diabetic mice

Abstract

This work was concerned with isolating and molecular weight determination of the proteinous compounds isolated from the cold and boiled aqueous extract of Marus Albal L. using different biochemical techniques . Also this study indicated the effect of the proteinaceous compounds Ac, Bc and Ab, Bb on some biochemical parameters including glucose, cholesterol and total lipids levels in blood serum and glycogen content in liver tissues in normal and diabetic mice . A single intraperitoneal injection of these isolated compounds with a dose of 75 mg / kg body weight was used .As well as pancreas were removed and stained with H and E of pancreatic sections. Results indicated that intraperitoneal injection of insulin and all the proteinaceous compounds Ac , Bc and Ab, Bb obtained by gel filtration chromatography from the plant used had hypoglycemic effect on serum glucose level in normal and diabetic mice. The rate of decrease was from (18.2) to (43.7) % in the normal and form (29.57) to (50.20) % in the diabetic mice respectively. While compounds (Bb) showed a negligible to an increasing effect (3.91) % in the normal and (7.99)% in the diabetic mice. Also the highest decrease was obtained for compound (Ac), this decrease were (16.8 )% and (15.73) % for serum cholesterol levels in the normal and the diabetic mice respectively .As well as the highest decrease was obtained for compound (Ac) , this decrease were(23.62) % and (28.88) % for serum total lipids levels in the normal and the diabetic mice respectively. Also a decrease between (5.8 , 14.1) % and (6.4 , 12.9) %  glycogen content in liver tissues was obtained when the normal and in the diabetic mice respectively were injected intraperitoneally by the proteinaceous compounds Ac, Bc and Ab , Bb from plants used. Finally alloxan induced diabetic mice group, the endocrine pancreas histologically showed decreased in the size and number of Langerhans islets with vacuolar degeneration and necrosis of almost all cell in the atrophied islets as compared with control group. The histomorphometic study of the pancreas of the treated group didn't show a significant change of the pancreatic tissue.
