[Thoracic and abdominal injuries caused by safety belts (author's transl)].

Based on experiences over half a year authors found that the introduction of safety belts, beside obvious advantages, resulted in new types of injuries. They describe own experiences and draw attention to heart contusions joining thoracic fractures, and to possible thoraco-abdominal organ injuries with characteristic symptom free or delayed appearance, caused by blount trauma.

Experiences with L-deprenyl in Parkinsonism.

In about 2/3 of the cases studied (152 patients), the combination of deprenyl and the substitution-therapy has a favourable effect as it tends to normalize motor activity. Although the administering of deprenyl renders neither L-Dopa nor the decarboxylase inhibitor superfluous, their side effects can be slightly reduced as their dose is reduced. Therefore it is advised to give all patients a trial with this drug.

[Comparison of the effect of catecholamines on the blood flow in the coronary and in the femoral circulation].

The effect of adrenaline and noradrenalin on the coronary circulation was studied in narcotized dogs. In 14 dogs every 20 seconds the venous blood from coronary sinus was examined. In a second series of animals the blood flow in the coronary artery and in the femoral artery was recorded continuously after intraarterial, resp. intravenous injection of catecholamines. In some experiments a constant perfusion pressure in coronary and femoral systems was maintained by help of a stabilizing device. The results of these experiments unequivocally proved that application of catecholamine was always followed by dilatation of the myocardiac and constriction of femoral vascular system. In no case catecholamines caused initial vasoconstriction of coronary vessels. The reasons for that paradoxical efficacy are discussed.
