A 43 year old man suffered from the involuntary movements since 10-th year of age. Those movements, initially mild, have progressed in the course of the disease. In the neurological examination the dystonic involuntary movements of the neck, trunk and limbs, more expressed on the right side, were observed. The laboratory findings were normal, except the level of dopamine beta-hydroxylase, which was increased. Similar results were observed also in the closest relatives of our patient. After the treatment with high doses of L-Dopa we achieved a considerable decrease of the symptoms.

Research was conducted upon 28 patients with a diagnosis of endogenous depression after their pharmacological treatment with imipramine or chlorimipramine. The investigation considered the interrelationship between psychophysiological parameters (heart rate, respiration rhythm, postural muscular tension) and the indices of the cholinergic and adrenergic systems (kinetic parameters of choline transport in the blood; Vmax, the activity of plasmic pseudocholinesterase, Che; blood acetylcholinesterase AChE, monoaminoxidase in blood platelets, MAO; and dopamine beta hydroxylase DBH). The results indicate that during relapse of endogenous depression there occurs an imbalance in the cholinergic-adrenergic systems which may be the result of some somatic symptoms typically found in the depression syndrome. The appearance, after pharmacotherapy, of a correlation between the indices of the activity of the cholinergic system with the respiratory rhythm suggest that the part played by the cholinergic mechanism in the regulation of autonomic processes normalizes itself during the course of successful therapy. The appearance of characteristic correlations between the activity of the cholinergic and adrenergic systems and the psychophysiological parameters in the presence of relatively low psychological stress seems to accompany successful treatment with imipramine and chlorimipramine.
