Abstract:

Metabolic syndrome is a fatal endocrinopathy, which is progressed towards pandemic, and characterized by insulin resistance, abdominal obesity, dyslipidemia, diabetes mellitus, hypertension and coronary artery disease (CAD). In the present study, it is aimed to investigate the histomorphological and histochemical changes caused by the metabolic syndrome in rat kidneys. For this purpose, the material was divided into two groups: 10 rats in the control group and 15 rats in the experimental group. During 16 weeks, while tap water was given to control group rats, water including 20% fructose solution was given to experimental group rats as drinking water. At the end of the study, Crossman's triple staining method was performed to determine the histological appearance and histomorphological changes in the sections taken from the kidneys. Periodic Acid Schiff Reagent (PAS) staining method was performed for histochemical analysis. The results of the study showed that the tubulus proximalis diameter, tubulus proximalis glycogen density, and glomerular mesangial matrix density increased, corpusculum renis diameter, width of cavum glomeruli and ascending limb of Henle’s loop diameter decreased. In conclusion, it is demonstrated that metabolic syndrome may adversely affect kidney histology and cause renal damage.
