PLASMA CONCENTRATION OF HORMONES AND LIPOPROTEINS AFTER HYPERTHERMIC BATH IN MAN

Publisher Summary This chapter discusses a study to analyze the plasma concentration of hormones and lipoproteins after hyperthermic bath in man. Fourteen healthy volunteers, aged 20–22, participated in the experiments. During the study, the volunteers were hospitalized and had identical daily regimens and diet. All experiments were performed in the morning after an overnight fast. After the measurements of sublingual temperature, the first control blood sample was taken. Then the subjects were immersed into thermal water (39°C) in standing position for 30 min. Immediately after the bath, the sublingual temperature was taken again and the second blood sample was drawn. The subjects were submitted to the bath procedure every morning for 10 days and on the tenth day, blood sampling and temperature measurement were repeated. Cholesterol and triglycerides were determined prior to and after the first bath only. The concentration of cholesterol in plasma was analyzed. It was found that during the bath, the average increase in body temperature was 1.2±°C. Before the bath, the plasma level of growth hormone was within the physiological range. A 30-min stay in thermal water induced highly significant increases in hormone levels.
