(II) Re Influence of Carotid-sinus Pressure Test on Skin Capillaries. The study was made to test the influence of carotidsinus pressure to determine the effect on the pulse rate, blood pressure and capillaries. Experiments were made on 35 persons, sick and healthy included. The following data was obtained : 1) 77.1% showed decrease of pulse rate by 10 or more beats per minute ; 77.1% showed lowering of blood perssure by 5 or more mmHg. on application of the pressure. In most cases, heart reflex and blood-vessel reflex occurred analogically and simultaneously. 2) In majority of cases, capillaries were slightly extended and elongated, the number of visible capillaries increased and the blood circulation was somewhat hastened by the application of carotidsinus pressure : In minority of cases, though, there were seen some who showed slowing of blood flow or no change. The blood filling of capillary loops and subpapillar venule plexus increased, and base color tone generally was deepened. 3) It is hardly possible to say that the changes in capillaries by application of the carotdsinus pressure were more prominently noticeable in cases of arterio-sclerotics hypertensives and/or angio-neurotics who had marked biood pressure descent.
