An attack of Raynaud's Phenomenon (RP) is characterized by blanching of the fingers in response to cold or emotional stimuli.
We analyzed the effect of ninjinyouei-to on RP in patients with MCTD. Subjects in this study comprised 19 patients, two males and 17 females, with a mean age of 38 years, and a mean duration of disease of 57.6 months. The study was performed at a time when RP occurred frequently in our country, that is in the period from November 1992 to March 1993.
We administered 9.0g of ninjinyouei-to to each case for four weeks and measured the surface skin temperature of the hands before and after medication with a thermograph using a Thermoviewer-JTG 3300.
There was a significantly higher temperature on the left first finger-tip after medication. Our thermographic findings in this study demonstrate a quantitative efficacy of ninjinyouei-to on RP in MCTD.

Daily energy expenditure has been measured by the physical activity recording and/or the questionnaire method. Recently, the accelerometer or pedometer is used to measure daily energy expenditure. The purpose of this study was to examine validity of the pedometer with accelerometer and to compare the daily physical activity between young and older Japanese. To examine validity of the pedometer, 10 young subjects worn the pedometer (Lifecorder) on the waist and then performed the walking test. Energy expenditure was measured by the expired gas analysis during the test. Fourtythree young and 54 older subjects worn the Lifecorder on the waist during free-living condition for 14 days. The intensity of Lifecorder had a high correlation with the physical activity intensity (METs) (r=0.958, P<0.001) . In the free-living condition, daily energy expenditure was 2171±305 kcal in young and 1617±196kcal in older (P<0.001) . Total step in young was significantly higher than older (young: 9490±2359 steps ; older: 6071±2804 steps, P<0.001) . There was no significant difference in the duration of physical activities at the Lifecorder intensity 1 such as desk working, watching TV sitting on a sofa and driving a car. However, the duration more than the intensity 2 corresponding to 2.2 METs in young subjects was longer than that in older (P<0.001) . We concluded that in older subjects, not only amounts of daily energy expenditure but also intensities of daily living were lower compared to the young subjects.

Treadmill exercise tolerance test(Modified Bruce Method) was performed with and without warm water bathing (WWB, 41°C, 10min) in 14 healthy aged men and women over 65y. o. (68.6±6.0y.o).
Increase in HR, BP and PRP during exercise was reduced after WWB. Duration of exercise and ST depression and occurrence of arrythmia during treadmill exerecise were significantly improved after WWB. Fatigability of the legs and Borg's index were also decreased aftr WWB. These results indicated the improvement of exercise tolerance after WWB was probably due to the increase in cardiac functions and collagenous viscosity (extensivility) of the musculoskeletal system.

The effects of the bathing on renal function were studied in 12 healthy men (32.3±7.7y. o.). The subjects took 41°C, 10min bathing and kept warm by a blanket for 30min, and then a mixture of 10% para-aminohippurate (PAH, 0.3ml/kg) and 10% sodium thiosulfate (NTS, 80ml) was infused intravenously. Clearance of PAH and NTS was calculated as the index of renal plasma flow (RPF) and glomerular filtration rate (GFR). PAH and NTS clearance test was also done at rest without bathing in another day. Blood Pressure (BP), Heart rate (HR), cardiac output (CO), sublingual temperature by electric thermista as deep body temperature were measured during the experiment. 30min after bathing, sublingual temperature was significantly increased by 0.9°C, and CO by +40%. After bathing, renal plasma flow (PAH clearance) significantly increased from 388.5±158.9ml/min to 572±170.7ml/min. Glomerular filtration rate (NTS clearance) was, however, unchanged from 115.6±37.3ml/min to 119.3±51.3ml/min. Filtration fraction (GFR/RPF) was significantly decreased. These results indicated that GFR was not improved by bathing although CO and RPF was increased by thermal vasodilation effect. The mechanism of unchanged GFR, despite of increased RPF, is probably that glomerular filtration pressure unchanged by thermal vasodilation of glomerular efferent and afferent arterioles.

Objective: Warm water immeresion (WWI) has been customary in Japan as useful thermal therapy. However, a comprehensive investigation of the effects of WWI on internal organs has never been undertaken. The purpose of this study was to examine the effects of single WWI on indocyanine green (ICG) excretion in healthy humans. Subjects: 23 healthy males. (32.6±1.9 [mean±SEM] years) Methods: 1CG was administered intravenously (0.5mg/kg) to calculate excretion rate (ER). ICG injection was given before and after WWI (10min at 41°C). Sublingual temperature (ST), blood pressure (BP), heart rate (HR), and cardiac output (CO) were simultaneously measured by noninvasive methods. Results: Significant changes were observed after WWI. These included an increase in ST, HR, and CO and a decrease in systolic BP (p<0.01). ER significantly decreased from 0.210±0.015 to 0.168±0.009 (p<0.01). Front-back ratio of ICG-ER which was calculated in order to evaluate the effect of aging increased significantly with age (R=0.582, p<0.0001). Conclusion: These results indicate that although CO increased due to the vasodilating effects of WWI, hepatic blood flow decreased after WWI and its response reduced with age even in before middle age.

An 84-year-old man with a thoracic aortic aneurysm underwent total arch replacement with selective antegrade cerebral perfusion. Immediately after the operation, respiratory distress and hypotension developed and Chest X-ray films and computed tomography showed bilateral lung edema. Echocardiography showed a small, underfilled left ventricle, but with preserved systolic function. We suspected transfusion-related acute lung injury (TRALI), and started sivelestat and steroid pulse therapy. His respiratory condition gradually improved, and he was discharged on postoperative day 78. The diagnosis of TRALI was confirmed by positive test results of an HLA class I antibody in the transfused fresh frozen plasma and T- and B-cells of the patient. TRALI should be considered as a cause of acute lung injury after surgery with blood transfusion.

Various types of surgical techniques have been reported for the closure of complicated PDA, since Morrow first described an innovatory operative method. At our institute, extracorporeal circulation has been frequently used as a support measure for these operations to ensure the safety of the operation. Ten patients with complicated PDA were operated under extracorporeal circulation. All patients but one were adults. The reason for use of extracorporeal circulation included age, presence of atherosclerosis or calcification of the ductus, short neck ductus, ductal aneurysms, right sided descending aorta and recanalization after previous ligation. The ductus was approached through the left lateral thoracotomy in 8 patients and median sternotomy in 2. The Morrow procedure was performed in 2 patients. No hospital death occurred, although the mean duration of the hospital stay after the operation was longer in these cases than in cases with simple PDA. We conclude that the use of extracorporeal circulation is safe and effective for the closure of complicated PDA.
