Psychophysiological typological aspects in relation to the risk for coronary heart disease and to the work load.

The application of Jenkins activity survey allowed to assess the behavior pattern of 76 managers (white collar workers) exposed to professional stress. In 54-82% of the subjects the type A behavioral pattern was found; conventional risk factors for coronary heart disease existed in more than 50% of the cases. Individual advices to prevent or restrain the coronary risk were given.

Effects of 6-hydroxydopamine on the carbohydrate metabolism of skeletal and heart muscles in rest and during exercise.

A mild 10 min exercise, induced by "in vivo" electrical stimulation of the rat gastrocnemius, causes decreases of the muscle glycogen content (G) and phosphorylase alpha activity (PA), and an increase of its overall glycolytic capacity (OGC); in the myocardium, PA decrease of liver glycogen were brought about by peripheral administration of 6-OHDA; these were probably also related to tissue hypoxia. Modifications elicited by exercise in 6-OHDA treated rats (increase of PA, but no modification of G and OGC in GM; decrease of G in the liver; decrease of OGC in M) suggest some impairments of the ability to adapt the tissue metabolism to increased energetic needs.

The influence of moderate hyperbaric environment on the sensory-neuro-motor processes in man.

Thirteen healthy male divers were repeatedly studied during the exposure to a moderate hyperbaric environment of 4--6, 7 and 9 ATA, in a hyperbaric chamber. The maximal duration of the exposure was 35 min, and that of decompression 90 min. As compared to the dynamics of the changes found in 14 controls, under hyperbaric conditions a significant increase in the number of static tremor, an impairment of the sensory-motor performance in O'Connor's and in the rotation test were found and also of the muscular strength and resistance to fatigue (this latter only at 9 ATA).

The influence of moderate hyperbaric environment on some nervous functions and on the sympatho-adrenal and adreno-cortical activity in man.

Thirteen healthy males were repeatedly studied during the exposure to a moderate hyperbaric environment of 4--6, 7 and 9 ATA, in a hyperbaric chamber and partly during immersion in sea water (3.5--4 ATA). The maximal duration of the exposure was 35 min and that of decompression 90 min. As compared to the dynamics of the change found in controls, under hyperbaric conditions a significant prolongation of the visual reaction time (especially during sea dives), and an impairment of the mental performance in an arithemetical calculation test were found. There occurs an increase of the excretion in urine of cortisol, epinephrine and vanillylmandelic acid, especially after immersion in sea.
