[Quantitative morphological studies on the zona glomerulosa of the rat adrenal gland. II. Effect of potassium and heparin on the zona glomerulosa].

Authors studied the effect of potassium and heparin on the zona glomerulosa of rats by stereological methods. As the effect of potassium tolerance test the weight of the adrenals, the wideness and volume of the zona glomerulosa, the number and the volume of the cells of it, further the volume of the mitochondria and nuclei in each cell have shown significant increase. After treatment with heparin the wideness of the zona glomerulosa and the volume of the mitochondria appeared to be decreased. Results are in accordance with the aldosterone-level-increasing effect of potassium and with the antialdosteron effect of the heparin.
