[The significance of microproteinuria for the diagnosis of kidney involvement in hypertensive disease and secondary forms of arterial hypertension].

N-acetyl-beta-glucosaminidase (NAG) activity, the concentrations of microalbumin (MA) and B2-microglobulin (B2-MG) were measured in urine of 50 healthy subjects and 200 patients suffering from arterial hypertension (AH) with preserved renal function, including patients with essential hypertension (EH), stages I and II, chronic pyelonephritis (CPN), chronic glomerulonephritis (CGN) and vasorenal hypertension (VRH). The healthy subjects, the patients with stage II EH, and those with secondary forms of AH demonstrated significant differences in NAG activity in urine. A positive correlation (r = +0.

[The effect of physical training on the indices of the general hemodynamics and kinin-kallikrein system activity in hypertension patients].

Forty men aged 30-60 years suffering from stage-II essential hypertension were examined for the general hemodynamics, the level of prekallikrein (PK) and kallikrein-like activity (KLA) of blood plasma, and kallikrein excretion with urine. The examinations were made before and after 30 weeks of exercise. Before such a course of exercise the response of the cardiovascular system and of the kinin-kallikrein system (KKS) to exercise was characterized by a significant rise of systolic, diastolic medium-hemodynamic arterial pressure, heart rate and kallikrein excretion with urine together with the lack changes in PK and KLA of blood plasma.
