[Simultaneous occurrence of autoimmune hepatitis type III and autoimmune thyroiditis type III (Graves disease)].

The case of simultaneous clinical manifestation of autoimmune hepatitis (AIH) and autoimmune thyroiditis was described. The authors presented diagnostic difficulties often related to AIH. The interdependence between the liver and thyroid gland function was emphasized.

Plasma renin activity, aldosterone and cortisol levels during physical exercise in essential hypertension.

Plasma renin activity, aldosterone and cortisol levels, as well as renal blood flow were studied in borderline and established hypertensive patients and in healthy control subjects at rest and following graded dynamic upright exercise. Resting plasma renin activity was elevated in established hypertension, renal blood flow at rest was decreased in patients with borderline hypertension but its per cent decrease during exercise was similar in all groups. Following exercise, plasma renin activity increased in all groups but a step-wise increase with graded exercise occurred only in borderline hypertension.

Plasma and urinary catecholamines and metabolites during physical exercise in essential hypertension.

The effect of physical exercise on plasma catecholamines and urinary catecholamines and metabolites was studied in 11 patients with established essential hypertension, 5 patients with borderline hypertension, and 9 healthy volunteers. Resting plasma noradrenaline and the changes following exercise were similar in all the investigated groups. Although the resting urinary noradrenaline excretion was similar in patients and in controls, an exaggerated increase of noradrenaline excretion occurred in hypertensive patients during physical work.

Plasma catecholamines and renin activity in response to exercise in patients with essential hypertension.

1. The effect of physical exercise on blood pressure, plasma catecholamines and plasma renin activity was studied in fourteen patients with essential hypertension and in eight healthy subjects. 2.
