Plasma Na, K, Cl, Ca, P didn't or moderately be altered by exposure to acute heat in sauna bath (20 mn, 80 degrees C, relative humidity 15-20%). However, CO2T decreased, ARP, aldosterone, ACTH, PRL increased, and PTH wasn't modified.
Plasma glucose regulation is not deeply modified by attending a lecture or setting for an examination. Nevertheless blood glucose and IRI are respectively higher and lower before examination than lecture. These modifications can be due to a short increase of catecholamine secretion before examination.
In man, increase of renin and aldosterone levels in sera resulting from a brief and heavy muscular exercise on bicyle ergometer is notably reduced but not abolished by massive hydration.
Our aim was to study the adaptation of energetic metabolism to muscular activity and the effects of training upon these adaptations. So we realized swimming and running tests on young healthy adults, selected in "trained" and "untrained". The effects of muscular activity were reflected by a raise of serum F.F.A., clearly noted in "untrained" subjects ; the levels of glucose and growth hormone both raised, but especially in "trained" subjects. Cortisol level raised in varying degrees while insulinemia presented little changes.

The authors report one case of parathyroid adenoma in a 59 years old woman having received a cervical radiation therapy 38 years previously for suspected Basedow's disease. The cause and effect relationship between the cervical radiation and the appearance of the parathyroid adenoma seems to be established in the light of animal experimentation on one hand, and identical results found in the medical litterature on the other hand.
