Morphoquantitative study of the aorta’s wall in aerobically trained elderly wistar rats
The aim of the present study was to evaluate under morphoquantitative aspects possible alterations in the ascending section of the Aorta’s endothelium of elderly Wistar rats (16 months of age) trained at an anaerobic threshold intensity. Ten male animals were divided in two experimental groups (cont...
