EFFECT OF AQUEOUS AND ALCOHOLIC EXTRACTS OF ALOE VERA ON RATS EXPERIMENTALLY INFECTED WITH ENTAMOEBA HISTOLYTIA AND INDUCED DIABETES MELLITUS

Abstract

The current study was designed to investigate the effect of aqueous and alcoholic extracts of Aloe vera plant on the tissues of white rats of the type albino, aged 6 weeks, and weighing 250–280 grams, which were taken from the animal house of the College of Veterinary Medicine/Tikrit University, and these rats were placed in special cages at home. The animals were spread with sawdust with care for the cleanliness of the cages, and the animals were placed throughout the study period under appropriate laboratory conditions in terms of ventilation, temperature, and adequate lighting. They were provided with water and the prepared ration continuously and in sufficient quantities until the end of the experiment. The microscopic examination of tissue sections taken from rats infected with the amoeba parasite The tissues of patients with newly diagnosed diabetes have pathological changes in the large intestine (colon) and the liver, as it was noted that the intestinal mucosa contains the degeneration of a number of epithelial cells, covering the intestinal mucosa with the degeneration of a number of those cells. In the liver, the liver was observed in the positive control group and the presence of histological changes It was observed around the liver tissue in which the capsule was sloughed off and the liver parenchyma spread in which the hypertrophy of the liver cells spread and the cytoplasm lost most of its pigment with Some of the nuclei of hepatocytes thickened, and hepatocytes appeared compact as a single mass
