Morphofunctional characteristics of the kidneys in chronic endotoxemia against the background of hyperthyroidism.

Simulation of chronic endotoxemia in rats leads to the development of nephropathy and nephrosclerosis. Kidney involvement was more pronounced in animals with endotoxemia developing against the background of hyperthyroidism. Direct effects of bacterial LPS and its secondary effects mediated through circulating LPO products under conditions of thyroid hormone excess caused damage to the renal tissue. Immunohistochemical studies demonstrated higher expression of apoptosis markers in nephrocytes of the proximal tubules in rats with hyperthyroidism.
