[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.

[The hemodynamic and neurohumoral reactions induced by submaximal dynamic and isometric loading in hypertension patients].

Changes in systemic hemodynamics and plasma catecholamine levels during and 4 min after the end of bicycle and isometric leg exercise were studied in 12 hypertensive patients. Dynamic exercise increased heart rate more and blood pressure less than isometric exercise; plasma norepinephrine (NE) level rose by 109%. Isometric exercise increased NE level only by 18%, but maximal changes (46%) occurred during recovery, probably reflecting a washout of NE from active muscles after the end of isometric contractions.

[Interrelation of the antibiotic sensitivity (resistance) of staphylococci, clinical forms of the infection and production of protein A].

Two hundred and thirty-two strains of Staph. aureus isolated from patients with staphylococcal infections were studied. The strains were isolated from the blood of patients with sepsis, from the purulent foci on the skin and in the subcutaneous fat, from the nasopharyngeal mucosa of patients with tonsillitis and inflammation of the upper respiratory tract, from the sputum of patients with the pneumonia signs and from the pus of patients with otitis.

[Use of a countercurrent immunoelectrophoretic method for isolating antistaphylococcal antibodies and staphylococcal antigen in the blood serum of children with staphylococcal infections].

In cases of staphylococcal infection in children (osteomyelitis, purulent destructive pneumonia, phlegmons, abscesses) the use of counter immunoelectrophoresis (CIE) allowed one to detect antistaphylococcal antibodies (anti-poly-A beta) in 12.5-69.1% of cases and staphylococcal antigen in the blood serum in 6.

[Quantitative determination of protein A in strains of staphylococci isolated in the course of different clinical states and localization of the process].

The main properties of 370 staphylococcal strains isolated from the blood, pus, sputum and the throat washings of patients were studied, and the identification of these strains was carried out. The level of cell-bound protein A in the strains was determined in the hemagglutination test with erythrocytes sensitized with hemolytic serum. Out of 269 S.

[Activity of NAD metabolism enzymes and DNA concentration in the liver during chicken ontogenesis].

A reverse interrelation is established between the content of NAD and DNA in the chickens liver at different stages of ontogenetic development, especially pronounced at the stages of embryogenesis. The content of NAD which is the least in the liver of the 8-day embryos increases with development of chickens and reaches the maximum level by the 6-month age. The content of DNA is maximum in the embryonal period.

The ability of maternal antibody to increase the immune response in infants.

There is a relationship between the titre of antibody in cord blood to , diphtheria and tetanus antigens, and the antibody response of the babies to —diphtheria—tetanus vaccine. The response to this vaccine was greater in babies with antibodies in the cord blood.
