This tension allows the vessels a possibility of dilatation. Then the central artery of one (m ainly right )e ar was stimulated by an electrical stimulator under conditions of 30-300 Hz,0 .1-10 ms,0 .5-1.0m A,a nd 30sec-1min. The vasoconstrictive and vasodilatative effects were detected by using thermistors on the both-side central arteries and partly by a laser-Doppler flow meter. 1) For 26 among total 45 electrical stimulation trials,va soconstriction of the central ear artery occurred. 2) For 5a mong 45 trials,v asodilatation occurred. For the remainded 14,t he effect was too small to be distinguished from irregular vasomotor fluctuations. 3) In two cases,co ld induced irregular vasooscillation was fascilitated and in other two cases,it was inhibited by electrical stimulation. 4) Similar pattern changes as those in stimulated ears were seen in not-stimulated ears for every electrical stimulation. Even by abdominal electrical stimulation,th e same effects occurred in both-side ear central arteries. 5) Responsibility of vessels depended rather on the individuality than on the intensity of electric stimulation., Article, 環境科学年報12:114-118(1990)}, title = {家兎耳翼寒冷血管反射に対する皮膚電気刺激効果}, year = {1990} }
