[Clinical experience with heparinoid sodium pentosan polysulfate (SP54) in the treatment of cerebral ischemia].

Fifty-five patients suffering from acute cerebral ischaemia were treated with pentosan polysulphate (SP54) intravenously and subsequently orally. The control group consisting of 35 patients received the infusion solution and vasodilator drugs. The statistically significant changes appearing following infusion of SP54 include the following parameters: haematocrit, blood viscosity and cholesterol concentrations.

Adaptive processes in child and adolescent swimmers. Blood coagulation and viscosity.

Multifactorial studies were performed in child and adolescent swimmers in the early period of training and in a submaximum state of training in the year's racing period. Blood coagulation, viscosity, acidity, protein metabolism, muscle enzymes, ions, haematologic, cardiac and endocrine parameters have been investigated. In the early period of training, physical exercise resulted in fibrinolysis, and a decrease in the fibrinogen and prothrombin levels and the platelet count.

Investigation of adaptive processes in child and adolescent swimmers. Acid-base parameters of swimmers and weight-lifters.

Acid-base parameters of adolescent swimmers (capacitive sport) and of adult weight-lifters (athletoid sport) were investigated before and after training in the submaximally trained phase of a year-round training period. In swimmers, training induced incompensated metabolic acidosis, which persisted at 10 min after the training. This acidosis showed no correlation to the blood lactate level.
