With the object of studying the general physiological function of "Kyu", i. e. moxibustion or cauterization of the skin with moxa, I investigated, as the first step, its influence upon the revived perifereal blood-vessels and the heart of the toad, employing the blood serum af rabbits cauterized with moxa, and obtained the following results:- 1) When the blood-serum of cauterized rabbits (0.1 c.c.) acts upon the blood vessels of the legs of middle-sized toads, the phenomenon of the contraction of the blood-vessels teaches a maximum within 1-3 minutes after injection. Comparing this with the results obtained with blood serum collected before cauterization, we find that contraction of the blood-vestels appears more rapidly, and moreover the time required to dilate the blood-vessels is longer and the degree of dilutation less than in the control. 2) When the blood-serum of cauterized rabbits acts upon the revived heart of the toad, I recognized the fact distinctly that, while blood-serum collected after cauterization diluted about 100 times makes the heart increass its contractive power and increases the amplitude of each pariodic motion, blood serdm collected before cauterization, diluted 10 times produces the same result. Also, the lower the grade of dilution is, the stronger is the contractive power and longer the continuation of contraction becomes; and the amplitude of the motion of the heart is also inversely proportional to the grade of dilution of the blood-serum. 3) When the cauterization is performed every day, on the sixth day, as on the first day, the blood-vessels contract and the dilatation of the blood-vesseles appears within-4 minutes after the mexirnum contraction. On the 11the and the 17th day the contraction degins immediately ofter injection, but after that there appears no change. Heuce I believed that it has no influsnce on the 11th and the day. According to the abovo mentioned experimental results, it is possible to presume that owing to moxibustion there is an increase in some substances whsch causes the periphereal blood-vessels to contract and which accelerates the function of the heart. What these subctances are, whether they are due to an increase in adrenalin, or to the existence of some other substance- these problems must be elucidated by my future studies: Although I am inclimed to believe that the effect is probably due to an increase in adrenalin or an adrenalin-like substance, I content myself at present with reporting these experimental resulte.
