Treadmill Exercise Training Ameliorates Functional and Structural Age-Associated Kidney Changes in Male Albino Rats

Figure 4

Representative micrographs of H&E-stained renal sections of the exercised aged group (N = 10), clarifying amelioration of most of the age-related damaging effects. Slight exfoliation (arrows), few pyknotic nuclei P, and mild interstitial hemorrhage (arched arrows) are noted within some tubules. Few glomeruli show congested capillaries (double arrows). H&E: 40x, scale bar = 20 µm; (d): 100x, scale bar = 8 µm. N = number of rats.
