[The compartmentalization of membrane-bound thrombocyte calcium in arterial hypertension].

High contents of Ca2+ was revealed in thrombocytes' intracellular compartments in patients with essential hypertension. In response to different stimuli, large amount of Ca2+ can be released in the platelets of the patients which makes a considerable contribution to generation of the Ca2+ signal and activation of thrombocytes in cardiovascular diseases.

[The membrane-bound calcium of the thrombocytes in essential hypertension].

The investigation was aimed at analyzing membrane-bound calcium in platelets of patients with essential hypertension (EH) and of healthy persons. 55 men were examined. Of these, 38 presented with EH and 17 were healthy.

[Modification of a model of ventricular fibrillation by a combination of ligation of the interventricular artery and ultraviolet irradiation of autoblood].

The combination of interventricular artery ligation and extracorporeal intensive ultraviolet irradiation of autoblood enabled the researchers to bring down the threshold and to increase the frequency of ventricular fibrillations. The above finding has served as a basis for creating a new experimental model of delayed ventricular fibrillation with a higher possibility of its development.

[Lipids and the lipoprotein spectrum of blood in men engaged in intensive mental activity].

A group of 242 males, aged 35 to 45 years, employed as engineers in several research institutions, was examined. The examination was conducted in accordance with WHO recommendations. Among the biochemical indices the blood level of lipids (cholesterol, triglycerides) and the lipoprotein spectrum of the blood serum were determined by means of polyacrylamide gel electrophoresis.

[Diurnal fluctuations of blood lipids and sugar level in healthy persons and in patients with ischemic heart diseases].

Diurnal fluctuations in the level of cholesterol, phospholipids, triglycerides, NEFA and sugar in the blood of practically healthy subjects and in patients with ischemic heart disease, attended by hyperlipoproteinemia of the II and IV types, were studied. Investigations were made at 9 a.m.
