PHYSIOLOGICAL AND HISTOLOGICAL STUDY OF EXPERIMENTAL DIABETES MELLITUS BY ALLOXAN. -

Study included using exogenous alloxan (100 mg for every 1 kg of animal weight) for inducing experimental diabetes mellitus in rats. 46 rats divided for two groups, during the time of study glucose, glycogen levels estimated every week extend for 3 weeks. Also the study included histo-pathological effect on liver and pancreas. The experiment showed an increase in blood glucose, after 7 days, 14 days, 21 days of alloxan injection, values were (11,92 ), (15,89), (17,31) mmol/Lrespectively, glucose level of control group was (5.84 - 7.44 mmol/L). while glycogen level in liverat the same period was (0,72 ), (018), (0.075) mg/g. Control group glycogen was (3,18 ? 3.65mg/g) during 3 weeks of experiment. Histological examination of liver samples of ratswere traced pronounced signs of toxic hepatitis as a violation of the beam structure of the lobules, necrosis of hepatocytes, fat and protein dystrophy, the presence of infiltration of hematogenous cell clusters. In the control group was characterized by a uniform distribution with respect to the same hepatocytes for liver slices, hepatocytes and the structure of the test cells corresponded to the ratio of the classical histological characteristics of the active functioning of the liver. The number of β-cells in the islets of sharply reduced, in most of them marked vacuolization of the cytoplasm, reducing the size of the nuclei, chromatin condensation, in some cells - kariopik?noz. Presence of a lymphocytic infiltrate along the periphery of the islets, interlobular connective tissue edema, congestion of the capillaries; vascular stasis traced. - See more at:
