[Modification of psychic, autonomic and metabolic reactions during examinations by a single dose of beta-receptor blockers].

18 students of human medicine were checked during their state examinations when they were or were not administered the beta-receptor blocker Propranolol. In the present examinations under psychic stress Propranolol has no ascertaining influence on the experience parameters, but on somatic reactions in the cardio-circulatory system, the haematological system as well as in the influence on a series of laboratory-chemical parameters. While slighter heart rate, lower blood pressure, a slighter decrease of the absolute number of lymphocytes and a lower plasma cortisol level refer to less distinct reactions of demand under influence of Propranolol, in the region of the lipid parameters HDL-cholesterol and LDL-cholesterol changes develop in the sense of an at least situational increased atherogenic risk.
