[Detection of silent ischemia symptoms in patients with carbohydrate metabolism disorders].

Early detection of silent ischaemia plays an important role in prevention of sudden cardiac death. Glucose metabolism disturbances are important risk factor of ischaemic heart disease. More frequent occurrence of silent ischaemia in patients with diabetes mellitus has been reported in several studies.

[A test for evaluating specificity and course of tilt table testing based on two groups of healthy volunteers (adolescent athletic swimmers and controls)].

The aim of this study was to estimate the results of tilt table testing in two groups of healthy adolescents--swimmers and control. Cardio-vascular reactions on tilting were determined by the measurements of heart rate (HR), systolic (SBP) and diastolic blood pressure (DBP). The study was carried out in accordance with the Polish Cardiac Society procedure.

[Aztreonam--new antibiotic for treating infections caused by gram-negative aerobic bacteria].

Aztreonam is the first synthetic monobactam used in practical medicine. It is effective in Gram-negative aerobe infections. It inhibits the growth of most Enterobacteriaceae in concentrations below 2 mg/ml, and of Pseudomonas aeruginosa below 16 mg/ml.

Enzyme activities in hepatic venous blood under strenuous physical exercise.

In order to study the influence of physical exercise on liver function, experiments were performed in healthy volunteers subjected to controlled major physical effort. Blood samples obtained by catheterization of hepatic vein during exercise were analyzed for activities of LD (thermostabile and thermolabile isoenzymes), AlAT, SDH, ICD, AP and CPK, and these activities were compared with corresponding values in arterial blood samples taken simultaneously. Hepatic blood flow and oxygen saturation of hepatic venous blood were measured.
