The temperatures of skin, corium, connective tissue. muscle and rectum on the full moon, the moonless day and the crescent have circadian rhythms. The circadian rhythms of temperaturs on skin, corium, connective tissue and muscel have same tendency on the full moon and the crescent.
The temperatures of corium, connective tissue and muscle on the crescent are higher than that on the full moon at every time.
The temperature of corium is lower than that of skin, connective tissue, muscle, rectum at every time on the full moon, the moonless day and the crescent.

In recent years the biological rhythms has been concerned. Lately we recognized that there were differences of degrees by the constitutions on the skin-temperature and bodily temperature. On Sympathicotonie and Vagotonie the rhythms-widths of skin-temperature had difference, but their cycles are same. The cycie of armpit-temperature and that of skin-temperature are reverse. Therefore the skin-temperature is importhant about the circadian rhythms.

A 52-year-old man suffering from Behçet's disease had undergone 6 operations for recurrent aneurysms of the bilateral iliac and femoral arteries. Thereafter, the patient underwent graft replacement for abdominal aortic aneurysm. Six years later he complained of lower abdominal pain and back pain. Abdominal CT-scan revealed abnormality of the proximal anastomotic site. The proximal suture line was completely dehiscent. The distal edge of infra-renal abdominal aorta was closed with interrupted mattress sutures. A right axillo-iliac bypass using a Dacron graft was performed for arterial reconstruction of the lower extremity. The patient has been free of recurrence for 4 years after the operation.

This study was undertaken to elucidate the usefulness and problems of autologous blooddonation for the patients with low-lying placenta. Seventy-eight women with low-lying placentawho gave birth in our institution were retrospectively analyzed. Autologous blood donation wasperformed in 58 patients (74%). The median volume of donated blood was 300 mL. Patients withor without autologous blood donation showed no significant difference in the distance betweenthe edge of the placenta and the internal os of the uterus. Median blood loss due to intrapartumhemorrhage was 1183 mL. All 7 patients with blood loss of more than 2000 mL had donatedautologous blood. The donated blood was transfused in 9 of the 58 patients (16%) who underwentautologous blood donation. No patients underwent allogenic blood transfusion. Althoughautologous blood donation was expected to be useful for avoiding allogenic blood transfusion inthese patients with low-lying placenta, the high discard rate suggests the need for a strategy toselect those patients at high risk for blood loss requiring transfusion.
