Effects of physical training during the growth on the granulation of myo-epithelioid cells of the rat kidney.
The behaviour of the granulation of the myo-epithelioid cells of the juxtaglomerular apparatus of the kidney and its relationship with the plasma concentrations of renin, sodium and potassium, and plasma osmolality have been studied in male and female Wistar rats that have been subjected to a programme of moderate physical exercise throughout their period of growth. In the trained rats a significant increase in the juxtaglomerular granulation index and a significant decrease in plasma renin concentration has been observed, the changes being more prominent in the female animals. Moreover in the trained rats significant increases in plasma sodium, potassium and osmolality have been observed.
