[Plasma renin activity and aldosterone content in healthy men and women]

Renin activity and the blood plasma aldosterone content were studied in 72 healthy subjects by radioimmunoassay. An analysis of the data obtained was performed depending on the sex and menstrual cycles (in women). The results of the investigation indicate the most pronounced activity of renin-angiotensin-aldosterone system in males. The changes in renin activity and aldosterone content in the blood plasma of females are cyclic in nature, tending to the increased indices during the menstrual cycle folliculin phase.
