Histological changes in kidneys with chronic kidney diseases in cats, associated with the deposition of amyloid
The work is devoted to the study of histostructural changes in renal tissue in chronic kidney disease in cats associated with the deposition of amyloid. Studies of pathological material - kidneys - in 20 cats of both sexes, metis, at the age of 12-16 years, in whose anamnesis there was a preliminary diagnosis - chronic kidney disease. For histological studies, the sections were stained with red Congo. In all the animals studied, the disease was accompanied by the deposition of amyloid in the kidneys; Most often pathological protein can be found in the intima or adventitia of small blood vessels, interstitial tissue along the reticular and collagen fibers, as well as on the basement membrane of epithelial structures.
