The objective of this study was to investigate whether isometric resistance exercise (IRE) can attenuate musculoskeletal atrophy during unloading and accelerate its recovery during reloading. Twenty-six female Fischer 344 rats, aged 16 weeks, had their hindlimbs suspended for 3 weeks (unloading) ; 12 of these rats were allowed subsequent cage activity (reloading) for 3 weeks with or without IRE. IRE (stationary support on a cylindrical grid inclined 60 or 80 degrees) was done for 30 min/day, 6 days/week, with an additional load of 30% or 50% body mass attached to the tail during the unloading and reloading periods. The tibial bone and hindlimb skeletal muscles from four experimental and two age-matched control groups were evaluated with dual-energy X-ray absorptiometry, mechanical testing, and muscle mass measurement. Bone mineral density (BMD) was measured in the whole tibia and in 7 regions divided equally along the long axis of the epiphysis from proximal (R1) to distal (R7) . After unloading, fat-free dry mass (FFDM), bone mineral content (BMC), and BMD of the whole tibia decreased by 8%, 10%, and 6%, respectively. FFDM and BMC, but not BMD, returned to the levels of age-matched controls during reloading. Unloading-induced decreases in BMD were observed in the regions from the proximal epiphysis to the diaphysis (R1 to R4) and the distal epiphysis (R7) . The rate of decrease in BMD was regionally specific and was particularly pronounced (12%) in the most proximal region (R1) . These findings indicate regional variations in responses of BMD to skeletal unloading. The BMD in R2 to R4 remained less than that in age-matched control after reloading. No significant changes were observed in maximum breaking load, energy, and deformation after unloading and reloading. Hindlimb-unloading induced loss of mass in the soleus (38%), plantaris (14%), gastrocnemius (25%), tibialis anterior (8%), extensor digitorum longus ( 8%), and rectos lemons (17%) muscles, but the mass of muscles, except for the soleus muscle, recovered during reloading. IRE ameliorated the loss of mass in the soleus and gastrocnemius muscles during unloading but did not promote the recovery of mass in any muscles during reloading. Moreover, IRE showed no effect on bone responses after unloading and reloading. This lack of beneficial effects of IRE on osteopenia may be due, in part, to insufficient exerciseinduced load. We concluded that 1) regional analysis of BMD can be used to assess local bone metabolism, 2) the response of BMD to altered loading conditions does not necessarily depend on the response of muscle mass, 3) recovery from osteopenia progresses more slowly than that from sarcopenia, and a longer time than the unloading period is required to restore BMD. Further studies are needed to develop more effective countermeasures against osteopenia and sarcopenia.

The DCCT syudy report (in 1993) showed that long-term maintenance of near normoglycemia markedly delays the onset and/or progression of microangiopathic complications of type 1 diabetes. Now, intensive insulin therapy has been considered to be a standard treatment of type 1 diabetes. However, it brings about serious hypoglycemia three times as frequently as conventional therapy with split-dose insulin mixtures. If IDDM patients could predict their blood glucose levels, it would be beneficial to prevention of hypoglycemia and to strict glycemic control. We intended to research whether insulin-treated diabetic children in a diabetic summer camp could predict their blood glucose levels. The number of subjects was 28. They were elementary and junior high school children 9 to 16 years of age. They predicted their blood glucose levels before every meal and bedtime, and then monitored their blood glucose levels. Their HbA₁c was 7.6±0.3%, total daily insulin dosage 36.0±3.2U/day, and infection times 3.3±0.2/ day.
Measured blood glucose levels and predicted blood glucose levels were not distributed normally, but their natural logarithms (Ln (mBG), Ln (pBG)) were. Ln (pBG) (5.01±0.02) was significantly higher than Ln (mBG) (4.92±0.03) (p<0.01)
A positive correlation was found between Ln (mBG) (x) and Ln (pBG) (y) (y=0.359 x+3.239, r=0.495). Events of which Ln (pBG) was within±20% and±30% of Ln (mBG) were 124 (31.5%) and 175 (44.5%), respectively, of the total 393 events. As for the relationship between Ln (mBG) and Ln (pBG) at each time, a change of Ln (mBG) was significantly larger than that of Ln (pBG).
These results showed that prediction of blood glucose levels was difficult for type 1 iabetic children, especially when blood glucose levels were extremely high or low and when they fluctuated sharply.

Objective:It is very important that oxidative stress is estimated for us to understand a player's condition in the field of sports. The purpose of this study was to investigate whether electroacupuncture has an effect on exercise-induced oxidative stress.
Methods:Ten healthy male volunteers participated in both the electroacupuncture (EA) group and the control group in a crossover design. EA at a frequency of 2 Hz and optimum intensity was performed in the subjects for 10 minutes in both the medial vastus muscles. During ergometer exercise by ramp load, respiratory metabolism including the RC point was recorded as the indication of energy metabolism. Blood was collected from the fingertips of the subjects, and then their levels of oxidative stress (d-ROMs test) and antioxidative (BAP test) were determined by using a Free Radical Analytical System (FRAS4, Wismell Instruments). Six measurements were taken;at rest, immediately after EA and following exercise, and at 20, 40, and 60 minutes following exercise.
Results:The RC point was significantly prolonged in the EA group compared with the control group. The level of oxidative stress (d-ROMs test) in the control group increased significantly at 20 minutes following exercise compared with rest (before exercise) and this increase was sustained until 60 minutes after exercise. In contrast, it did not significantly change in the EA group. Whereas the antioxidative level (BAP test) in the EA group significantly increased immediately following exercise compared with rest (before exercise), it did not increase in the control group.
Conclusion:These results suggest that electroacupuncture might enhance the antioxidative level (BAP test) and inhibit the level of oxidative stress (d-ROMs test) by effecting a change in respiratory metabolism. We propose that electroacupuncture might be useful for sports conditioning.

The purpose of this study was to clarify some of the characteristics of race-walking, especially the relationship between walking speed and oxygen requirement, and stride in race-walking and normal walking, and to examine whether race-walking is effective for the maintenance and promotion of health.
The subjects were five male race-walkers (race-walker group) and five male college students (control group) .
The results obtained were as follows:
1. Under race-walk conditions, the highest speeds attained in the race-walker and control groups were 200-220 m/min and 160 m/min, respectively. Under normal walking conditions, however, the values were 140 m/min in both groups.
2. A lower oxygen requirement was observed at slower speed during normal walking and at a higher speed (over 130 m/min) during race-walking.
3. Oxygen requirement (ml/kg/100 m) in the race-walker group was minimal at 60-80 m/min during race-walking and at 60 m/min during normal walking. Values in the control group were minimal at 60 m/min under both walking conditions.
4. The oxygen requirement in the race-walker group was less than that of the control group under both walking conditions.
5. Under normal walking conditions, as the speed increased, both step-length and step frequency gradually increased, until step-length reached a limit of 80 cm. Thereafter, walking was maintained only by an increase in step frequency. However, in the race-walkes group, the subjects were capable of increasing their step-length further, and maintaining a higher speed (up to 220 m/min) .
6. It was suggested that race-walking is one of the most efficient exercises for maintaining and improving health.

Purpose：Methadone is an opioid used in Japan for the treatment of cancer pain. A thorough consideration of complex pharmacokinetics with individual differences and of serious adverse effects is necessary before switching to methadone; therefore, methadone is not yet widely used. We examined the analgesic and adverse effects of methadone through clinical cases and considered the clinical significance of methadone as an opioid analgesic for the treatment of cancer pain. Methods：The clinical course of 44 patients with cancer pain who were switched to methadone from other opioids was analyzed. Results：Out of the 44 cases investigated, 37 cases （84.1％） were successful. In the successful cases, pain intensity before and after methadone administration was reduced from an average of 7.5 to 2.8, respectively, on the numerical rating scale. Strong drowsiness （six cases） and nausea （three cases） were observed as adverse effects. However, no serious effects, such as QT prolongation and respiratory depression, were recognized. Conclusion：For patients with refractory cancer pain who require a high opioid dose, methadone is considered to be one of the alternatives in pain therapeutics.

Background: Methadone can only be administered orally in Japan. However, it is unclear how to treat pain when patients become unable to take methadone orally because of the progression of the disease. Aims: To assess retrospectively end-of-life pain control management after patients become unable to take methadone orally. Methods: Twenty-eight patients with cancer pain undergoing treatment with oral methadone died at a palliative care unit between April 2013 and September 2014. All patients died of cancer and were unable to swallow before death. We assessed pain control approaches after the patients became unable to take methadone orally. Results: Twenty-one patients survived 1 day or longer after becoming unable to swallow. Methadone was switched to another opioid because of pain. Of these 21 patients, 10 patients survived for 1 week or longer after being switched to another opioid. At this point, methadone would be mostly eliminated from the blood circulation. Among these 10 patients, seven patients were treated with subcutaneous morphine, and three patients were excluded because their pain could not be evaluated. The conversion ratio from final oral methadone dosage to oral morphine equivalent dose of opioids used on the seventh day was 6.1. Conclusion: Even when patients become unable to ingest methadone, switching to other opioids may not always be necessary because of the long half-life of methadone when pain is absent at the end of life. If necessary, pain could be managed by switching to other opioids with a conversion ratio of 6.1.

Introduction: Paroxysmal atrial fibrillation (Paf) occurred in an inpatient who has been prescribed methadone for cancer pain in our palliative care unit, but oral administration of aprindine (antiarrhythmic agent) succeeded in defibrillation and methadone administration could be continued. Case: A 75-year-old man had developed multiple bone metastases after resection of thyroid cancer. Due to refractory cancer pain, switching from oxycodone to methadone was performed. Pain relief was achieved with methadone 40 mg/day and without QT interval prolongation. After methadone administration about 9 months, there suddenly became loss of appetite in the morning of one day. ECG examination revealed Paf onset. Aprindine 20 mg was orally administered for the purpose of defibrillation. After about 2 hours sinus rhythm was gained and later without recurrence. Conclusion: This case was considered to have the coincidental complication of paroxysmal atrial fibrillation in the course of methadone administration. If administration of antiarrhythmic agents is performed in a patient whom has been prescribed methadone, it is feared to lead to result in QT interval prolongation due to drug interactions. It is important to carefully select an agent that rarely leads to QT prolongation.
