[Structural bases for the minimization of function of the proximal epitheliocytes of the nephrons in a single acute overheating of the body].

Morphological bases of functional potentialities of nephrons were studied in the experiment with 115 two-month rats under conditions of general momentary hyperthermia. The size of renal corpuscles tends to diminish. It is found that damages occur mainly in epithelium of the proximal parts of nephrons with disturbances in the reabsorption apparatus. The lowered epithelium reabsorptivity is directed to provide survival of the cells and their further participation in reparative processes.
