The specificity of Jin-yu needling for urinary secretion was studied.
1); 15 healthy adult men were subjected to this experiment. After drinking water (500ml), acupuncture needles (No. 2 Seirin Co. Limited) were perpendiculary inserted to the jin-yu point depth of about 2cm, and left there for 10 minutes. The blood samples were collected at 60 minutes after drinking water, and urine volume and amount of Na, K, Cl, BUN, UA and Cre were measured.
As a result, a marked increase was observed in excretion of urine, UA, Cre, K and creatinine clearance. An upward tendency of Na, Cl and BUN excretion were found and it is correlated with urine volume.
2); Subjects were 11 healthy adult men. The group of acupuncture stimulation was divided as follows; a) a group, acupuncture needles were inserted at Jin-yu point [B-23], b) kyouseki point, c) sisitu point [B-52], d) daityou-yu point [B-25], e) I-yu point [B-21] and f) untreated contorol group. Urine were collected at 60 minutes after drinking water (500ml).
As a result, a significant increase of urine volume was observed in the group of stimulation at Jin-yu, Kyouseki, and Sisitu point (p<0.05).
Finally, it was suggested that the increase of urine volume was caused by a somato-visceral reflex.

For the purpose to increase peripheral blood flow of lower leg, low frequency electrical acupuncture was applied to the various meridian points such as Ciliao (B-32), Sanyinjiao (Sp-6), Xuehai (Sp-10), Zusanli (S-36), Jiexi (S-41) and Xuanzhong (G-39) on the patients of Burger's disease and intractable ulcer of lower leg. Peripheral blood flow was measu ed by a laser doppler flow meter. The results show that blood circulation of lower legs was increased by electrical acupuncture stimulation on bilateral Ciliao more than the other points and it was suggested that electrical acupuncture for bilateral Ciliao was helpful adjuncts to the treatment of ischemic disease such as Burger's disease and intractable ulcer.
