The effect of moxibustion on the endocrinosis elicited by disorders of the autonomic nervous system was investigated in hypophysectomized rat.
Natural gain of body weight was stopped, adrenals and testis became atrophied, urinary output increased, and the rectal temperature slightly dropped after hypophysectomy.
Applying moxibustion did not correct these synptoms.
Furthermore, in spite of electrolyte and amino acid metabolism, significant decrease of Na, K, Cl, Ca and a slight decrease of urea nitrogen and creatinine in urine was recognized. But these were not modify by moxibustion.
With respect to the adrenal cortical study, there were a slight increase of 17-OHCS and a mild decrease of 17-KS in urine. Moxibustion did not effect either 17-OHCS or 17-KS.

Effects of single moxibustion on platelet aggregation and ATP-release in mice have been studied. Male ddY mice (6 weeks old) were used as experimental animals. 15mg and 5mg of moxa were divided into 6 cones and mice were treated by each 3 cones at right and left LV-14. The electronic aggregometer was used for measuring platelet aggregation and ATP-release using whole blood. Platelet aggregation and ATP-release activities were determined by collagen (final concentration; 2μg/ml) and ADP (final concentration; 20μM) as inducers.
No significant changes on platelet and red blood cell numbers were found after the moxibustion with 15mg of moxa. However, white blood cell numbers were decreased at 1hr and increased at 24hr after the moxibustion.
After the moxibustion with 15mg of moxa, platelet aggregation activity induced by collagen showed no change, but the mild shortness of lag time was observed from 1 to 5hr. While, the mild suppressive effect on platelet aggregation induced by collagen was observed at 1 and 5hr after the moxibustion with 5mg of moxa.
After the moxibustion with 15mg of moxa, mild increase in platelet aggregation activity at 24hr and in ATP-release activity from 1 to 5hr was found. After the moxibustion with 5mg of moxa, an apparent increase in ATP-release activity was observed at 1 and 3hr.
These results suggested that the mild changes in platelet functions were closely related with the response of the coagulation and the fibrinolytic activity in mice.

As globalization also influences medical education, Chiba University has provided extensive study abroad programs. This paper reports a medical student's methods to prepare for using such programs and improve his English level, and outlines his actual experience of studying abroad during a 6-year period. It also discusses the significance of medical study abroad, focusing on the following 3 points: meeting medical leaders in other countries; establishing friendships with international medical students of similar age groups, while comparing Japanese students' abilities with international standards; and taking full advantage of being a student, as one is allowed to flexibly develop global perspectives only in his/her school days before starting a long career as a medical professional, to provide guidance for medical students toward such experience and career development based on it.

Effects of multiple moxibustion on platelet aggregation, blood coagulation and fibrinolytic activity in mice have been studied. Male ddY mice (5 weeks old) were used as experimental animals. 15mg of moxa was divided into 6 cones and mice were treated by each 3 cones at right and left LV-14. The experimental schedules of multiple moxibustions were 5, 10 and 15 treatments of twice a week. The electronic aggregometer was suitable for measuring platelet aggregation using whole blood. However, no significant changes on platelet counts, platelet aggregation and ATP release induced by collagen (final concentration: 2μg/ml) and ADP (final concentration: 20μM) were found after multiple moxibustions. 15 treatments of moxibustion induced the increase in fibrinogen contents and the decrease tendency of factor XIII activity. While 10 treatments of moxibustion showed the increase in PLG content and α2 PI activity. These results suggested that multiple moxibustions induce the reasonable reaction to keep a good homeostasis on blood coagulation and fibrinolytic system in mice.
