A relationship of meridian point-jingluo to secretion of insulin was evaluated by blocking the large intestine channel of hand-yangming.
Subjects were divided into three groups; (1) group of subjects in whom saline was injected in Quchi (LI-11), (2) group of subjects whose Quchi was cooled by an ice bag, and (3) group of subjects whose Quchi was pressed. Insulin secretion following acupuncture stimulation to Hege (LI-4) was measured in these groups. As a result, all three groups showed significant reduction in secretion of insulin and integrated insulin response for 60 minutes during oral glucose tolerance test.
The result obtained seems to suggest that stimuli given to Hege are blocked to transmit due to the interferance given to Quchi. This implies that blocking phenomenon of the jingluo take place in the large intestine channel of hand-yangming.

As reported in a previous paper, acupuncture stimulus at 8 meridian points, CV-3, ST-25, BL-20, BL-18, LI-11, ST-36, SP-8 and LV-3 revealed significant increase in supplementary secretion of insulin during OGTT in normal subjects.
In this study it was cauied out to evaluate effect on secretion of insulin during OGTT using the same 8 meridian points individually as acupuncture stimulus.
It was clear that supplementay secretion, total secretion and secretion response of insulin during OGTT showed a highly significant increase by acupuncture stimalus at LI-11 and supplementary secretion and secretion response of it resulted in a marked increase at LV-3. However, no significant changes of insulin secretion were observed at ST-36 and ST-25.
The results suggested that significant differeuce in insulin secretion existed among these meridian points which used popularly for diabetes mellitus.

A relationship of acupuncture stimulation to secretion of insulin was investigated by stimulating various meridian points which are usually used for the treatment of diabetes mellitus. As a result, it was demonstrated that Quchi (LI-11) is closely related to insulin secretion. This study was carried out to investigate a relationship of each of Hege (LI-4), Shousanli (LI-10), Jugu (LI-16), Yingxing (LI-20), which are located on the large intestine channel of hand-yangming, to secretion of insulin.
When stimulated by a 30 minutes placing needle, all four meridian points evidently increased secretion of insulin and integrated insulin response for 60 minutes during oral glucose tolerance test. Among others, Hege stimulation showed the most remarkable increase in insulin secretion.
The result obtained seems to suggest that is a close relationship between insulin secretion and the large intestine channel of hand-yangming.

Studies on relationship between insulin secretion and 8 meridian points, namely St-39, Ren-12, LI-11, UB-20, UB-18, St-36, Sp-8, and Liv-3 which are extensively used for the treatment of diabetes mellitus, revealed that LI-11 and UB-18 are closely related to secretion of insulin.
The twelve segmentations of Hirata, LI-11 corresponds to the 5th response zone of upper extremity region and UB-18 to the 5th response zone of truncal region, respectively. In order to investigate relationship between insulin secretion and the 5th response zone of Hirata's twelve segmentations, GB-10 of capital region, St-3 of collar region, SI-16 of facial region and Sp-6 of lower extremity region were stimulated by placing needle during oral glucose loading and insulin secretion was evaluated.
As a result, none of the meridian point locating in the 5th response zone in each region of Hirata's twelve segmentations showed positive relation to insulin secretion, except LI-11 of upper extrmity region and UB-18 of truncal region.
