title: [Histopathological changes in the kidney of experimental animals caused by lethal doses of thallium].
abstract: The experiment was carried out on 65 white male Wistar rats and 65 white male Swiss mice poisoned with thallium sulfate in doses 30-40 mg/kg body weight. The animals were sacrificed in the 4, 8, 24, 48th hours of experiment and their kidneys were submitted to light and an electron microscopic examination. Protein level in urine and urea level in blood serum of the rats were determined. With the light microscope necrosis of epithelium of Henle loops, hydropic degeneration, swelling and focal necrosis of epithelium of proximal convoluted tubules, and stromal oedema were seen. An electron microscopic study pointed out swelling and degenerative changes in the mitochondria, loss of microvilli in many cells, dilatation of endoplasmic reticulum and decrease of electron density of basement membranes. Urea level in blood serum and protein level in urine increased.
