(I) Re Influence of Valsalva's Pressure Experiment on Skin Capillaries. The study was made on the effect of Valsalva's Pressure on capillaries relative to blood pressure and pulse rate, on 38 persons (healthy and sick people). Examination of capillaries was carried out with Karl Zeiss's Capillary Microscop on nail edge of ring finger of left hand. The results showed : 1) The capillaries generally became expanded and elongated. 2) The number os visible capillaries increased. 3) The blood circulation in the capillaries became more rapid. 4) Strengthening of blood-filling in capillary loops and subpapillar venule plexus, and in their base color tone was noted. 5) The pulse rate showed increase of over 5 beats per minute in 50%, normal in 34.2% and decrease of over 5 beats per minute in 15.8%. 6) The blood pressure was noted as showing upward trend of over 9mmHg. in 42.1%, normal in 36.8% and downward trend of over 9mmHg. in 21.6%. 7) It seems difficult to consider that pulse rate, blood pressure, changes in capillaries, by application of Valsalalva's pressure, are consonant.
