Abstract
The aim of the work was to investigate the effect of 1,25 (OH)2 vitamin D3 on ß-endorphin and Cortisol secretion in vivo. ß-Endorphin, Cortisol, calcium and phosphate in blood were measured in ten healthy unstressed volunteers before and after 4-day oral administration of 1,25 (OH)2 vitamin D3 in doses of 3 µg/d. The biological effectiveness of the treatment was proved by a significant increase of calcemia as compared with control values (2.71±0.03 vs 2.57±0.02 mmol/l, mean±SE, p<0.01) and phosphatemia (1.18±0.06 vs 0.89±0.01 mmol/l, p<0.01). ß-Endorphin after treatment was 39.1 ±9.2 (vs 42.7±7.6) ng/l and Cortisol 369±35 (vs 377±31) nmol/l. In conclusion, in spite of the good compliance of the treatment, 1,25 (OH)2-vitamin D3 stimulates neither ß-endorphin nor Cortisol secretion in healthy subjects.
