The purpose of this study was to observe the effect on the change of heart rate and respiratory function by four kinds of different stimulation. We applied low frequency stimulation (1-30Hz) to 15 healthy volunteers. Each subject received stimulation at both 1Hz and 30Hz on Hegu (LI4)/Kong zui (L6) and rhomboids muscles.
The results indicated that a 1Hz current injection on the rhomboids muscle was the most effective for the respiratory function. An increase in the forced vital capacity (FVC) and the forced expiratory volume in one second (FEV1), and a decrease in the peak expiratory flow (PF) were observed. The change showed a similar tendency to that of a 1Hz stimulation to the rhomboids muscles of the patients wish asthma. This results suggests that the clinical application of acupuncture stimulation is feasible for respiratory diseases.
We also observed a correlation between the respiratory function and the autonomic function of heart on the 30Hz stimulation using points Hegu (LI4) and Kong zui (L6).

1. 5-HT inhibits spontaneous fluid secretion as well as stimulated secretion with secretin (cAMP mediated) or ACh (Ca2+ mediated) in the isolated guinea pig pancreatic ducts. 2. The inhibitory effect of 5-HT is reversible and is dependent on the concentration in the range 0.01-0.1 microM, which is much lower than those that affect intestinal motility and secretion. 3. The 5-HT3 receptor in duct cells appears to mediate the inhibitory effect of 5-HT. 4. [Ca2+]i is unlikely to mediate the inhibitory effect of 5-HT.

A 56- year-old woman visited our hospital complaining of right hypochondralgia. X-ray and endoscopic examinations revealed Borrmann 2 type gastric cancer in the anterior wall of an upper part of the stomach. Ultrasonography showed an echogenic mass in the suprarenal area. The mass which had septal formation within it, was about the same in density as fat on computerized tomography, and was hypovascular fed by the right inferior adrenal artery on angiography. These findings suggested that the mass might be adrenal myelolipoma. After total gastrectomy and right adrenectomy were done, histopathological study confirmed that the case is adrenal myelolipoma associated with Borrmann 2 type gastric cancer. In Japanese literature, only 54 cases of surgically resected adrenal myelolipoma have been reported, and this is the second case of adrenal myelolipoma associated with gastric cancer.
