Insulin was used to deplete the adrenalin stores of rat adrenal medulla cells. Release of secretion was observed to occur by exocytosis. In addition, during the stages of massive release of secretory granules, the insulin-treated preparations showed greatly enhanced endocytic uptake of horseradish peroxidase. The tracer was taken up within vesicles, tubules, multivesicular bodies, and dense bod...

The aim of this investigation was to compare the response of small arteries of the human tubo-ovarian vasculature to certain vasoactive agents. Ring preparations of the arteries were isolated and mounted in tissue chambers for isometric recording of wall tension. The arteries were exposed to the vasoactive agents adrenalin, prostaglandin F2 alpha and two vasopressin analogues. Adrenalin, prosta...

It has been shown by these experiments that after the removal of one superior cervical ganglion of a rabbit, 1/50 of a cubic centimeter of a 1:1,000 adrenalin solution (=0.02 of a milligram of adrenalin) per kilo of body weight injected intravenously, is practically the minimum amount that will produce in nearly all cases a perceptible dilatation of the pupil. In one out of eight animals this d...
