Thigh muscle cross-sectional area (CSA) and maximum voluntary isometric strength of knee extensor and flexor muscles were measured in 97 men (2065 years) and 162 women (2069 years) in sedentary Japanese adults. Each subject was assigned to one of five age groups (3^rd 4^th 5^th 6^th and 7^th decade) . Thigh muscle CSA was estimated by our developmental measuring system using an ultrasonographic device, which was connected to a PC for graphical processing. Muscle CSA for the 7^th decade in men was significantly smaller than that for the 3^rd decade. For women, muscle CSA were no significant from the 3^rd to the 7^th decade. The isometric knee extensor strength showed a significant decline with age from the 7^th decade in men, whereas there was no significant change with age in women. Isometric strength of knee flexors in men showed a gradual decline from the 5_th decade. The aging-associated reduction of muscle strength per muscle CSA in the extensors and flexors started from the 6_th decade in men. It was concluded that the size and strength of the thigh muscles begin to decrease simultaneously by approximately the 6_th decade in men, whereas there are no change until the 7^th decade in women.

Objectives : Persistent coldness is a common complaint for which Kampo, traditional Japanese herbal medicine, is often tried, because there is no definition or objective measure of subjective coldness in Western medicine. The aim of this study was to evaluate the efficacy of a common Kampo agent, tokishigyakukagoshuyushokyoto, and to identify key symptoms that would predict positive treatment outcomes for coldness.
Design : A retrospective cohort study.
Setting : 181 patients who complained of coldness without any organic abnormalities self-surveyed their health using a Kampo questionnaire database system on their first visit. Another 28 patients were assigned to verify the discriminatory predictability of treatment efficacy.
Interventions : Patients were treated with extract product, 7.5 grams a day for a month.
Outcome measures : Treatment efficacy as a binary response.
Results : Frequency and severity scales (0 to 4) for coldness decreased from 3.2 ± 0.7 to 2.1 ± 0.1 (p < 0.01)and from 3.1 ± 0.7 to 2.2 ± 0.9 (p < 0.01), respectively. Improvements in both frequency and severity of coldness were observed in 74.0% of patients. The status of tenderness in the iliac region, without upset stom ach or depression, was obtained as an appropriate model for the prediction of treatment effect, and its discrimi natory predictability was calculated as 84.4%. The predictive accuracy of the model was validated with 82.1% for the 28 new patients.
Conclusions : Coldness susceptible to tokishigyakukagoshuyushokyoto was very frequently accompanied by tenderness in iliac region, without upset stomach or depression.

Objectives : We evaluated the efficacy of tokishakuyakusan and kamishoyosan for patients who complained of feeling cold, and identified key symptoms that would predict positive treatment outcomes for coldness with these medicines.
Design : A retrospective cohort study
Subjects and Methods : The subjects were 188 patients who reported feeling cold. They were treated with tokishakuyakusan or kamishoyosan according to their Sho for more than one month. The relationships between improvement of cold sensation and 62 factors, including other symptoms noted at the first medical examination, were evaluated by means of cross-sectional analysis, followed by logistic regression.
Results : The factors of coldness of the abdomen (odds ratio, 5.0), vertigo (7.7), dimness of sight (16) and blushing (5.6), without anger (0.11) or tinnitus (0.025), were found to be predictors of a positive effect with tokishakuyakusan treatment (p < 0.001). The factors of hot flushes (14), without coldness of the whole body (0.099), and faint feeling (0.21) were significant for kamishoyosan (p < 0.001). This suggests that kamishoyosan can improve subjective coldness of the extremities (AIC -8.64), especially of the legs (-2.23).
Conclusions : Coldness in the abdomen was an important indicator for treatment with tokishakuyakusan, while coldness in the legs, but not in the whole body, was important in the case of kamishoyosan.

The purpose of this study was to clarify the effects of amino acid supplementation on mental and physical stress during severe exercise. 20 male college students were assigned to amino acid treated group (group AA) and placebo treated group (group P), each containing 10 subjects, and performed 1600 m-run relay for 24 hours. Each subjects of AA group received 1 g of amino acid powder, containing 34% of branched-chain amino acid (BCAA), after each work bout. The score of rating of perceived exertion (RPE) and category rate of pain scale (CPS) for each work bout were recorded. Scoring of profile of mood states (POMS) was performed and blood samples were drawn at pre-, mid-, and post-session. Total running distance was similar in both groups. In group AA, compared with group P, (1) total score of RPE and CPS through 25 work bouts and plasma cortisol concentration (C) at post- was significantly lower, and (2) molar ratio of plasma free testosterone concentration (FTS) to C (FTS/C) at mid- was significantly greater. In group P alone, plasma BCAA concentration, FTS, FTS/C, and POMS score about ‘tension-anxiety’, ‘anger-hostility’ and ‘vigor’ decreased significantly over time. Our data suggest that BCAA administration during severe exercise may diminish mental or physical stress, inhibit FTS/C decrease and be effective in maintaining aggressive mentality.

Introduction : We evaluated the efficacy of daisaikoto for patients with generalized fatigability or easy fatigability by multiple regression analysis.Subject and Methods : The subjects were fifty-three patients with generalized fatigability or easy fatigability, consisting of 6 males and 47 females, mean age 38 y/o (range 23-72), who were treated with daisaikoto according to Sho for more than one month. The relationships between the improvement of generalized fatigability or easy fatigability and 46 factors, including age, sex, height, body weight, hypertension and other symptoms noted at the first medical examination, were examined by multi-dimensional cross-sectional analysis.Results : The factors of sweating, hot flushes, sensation of something stuck in the throat, and feeling of fullness in the chest were significant. Improvement of objective tenderness on the sides of the abdomen and sweating formed the best subset of explanatory variables.Discussions : The sensation of something stuck in the throat and feeling of fullness of the chest often occur under Ki stagnation. The improvement rather than the existence of objective tenderness on the sides of the abdomen is assumed to be more important factor.

Headache is one of patients' major complaints at medical examination. And in Kampo medicine, we select prescriptions for them by taking not only headache, but also other symptoms into consideration.We present five patients with headache, whose symptoms were improved with tokishakuyakusan. Four patients (cases 1 to 4) had a background of menopausal symptoms and one (case 5), menstrual pain. Besides headache, other symptoms, such as vertigo, edema, and numbness of the fingers, were improved with tokishakuyakusan. Goshuyuto was not effective for headache in case 4, though it was effective to some extent in case 5, except for headache during her menstrual period. Headache during the ovulatory phase and/or pre- and early menstrual period disappeared when tokishakuyakusan was added to goshuyuto.Eleven cases of headache treated with toshakuyakusan, including these five cases, revealed that tokishakuyakusan was efficacious against migraine-type headache, which becomes worse during the menstrual period, and coldness. Although tokishakuyakusan should sometimes be distinguished from goreisan or hangebyakujyutsutenmato, it may be effective in patients with so-called “blood pattern” headache, associated with menstrual period and menopausal symptoms, and in patients with a heavy feeling of the head and vertigo.

It is important to treat patients with spleen qi deficiency not only with formulations for their deficiency, but also with formulations to improve qi stagnation.Rikkunshito plus Cyperi Rhizoma, Amomi Semen and Agastache rugosa, which improve qi circulation, was effective in cases 1 and 2 herein.We examined when and how to prescribe kososan with formulations for spleen qi deficiency, with reference to kosharikkunshito. Kososan and rikkunshito were effective in cases 3 and 4.Based on rikkunshito indication, a patient with weaker constitution was prescribed shikunshito (case 8), a patient with diarrhea and vertigo was prescribed shinbuto (cases 5 and 6), and a patient with severe coldness was prescribed ninjinto (case 7).Kososan played a supplementary role in treatment, and can be prescribed with other medicines.Not only gastrointestinal symptoms, but also various other complaints were improved by adding kososan to prescriptions for spleen qi deficiency.

Teian Azai classically described that summer heat was caused by humidity in addition to hot weather. It may occur after becoming chilled while asleep, enjoying the evening cool, and taking cold foods and drinks. Humidity and high temperature prevent qi circulation in the stomach. Therefore, he insisted that goreisan, a formula improving water circulation, could be applied for diverse symptoms caused by summer heat. We present two cases of patients with epigastralgia caused by cold foods and drinks in air-conditioned environments, whose symptoms were improved by goreisan. In prior treatment, anchusan in case1, and rikkunshito in case 2 were not effective for their epigastralgia. Nineteen cases of epigastralgia after taking cold foods and drinks in summer, including these two cases, revealed that goreisan was efficacious against summer epigastralgia with white fur on the tongue and a stuck feeling in the pit of the stomach. Abdominal fluid congestion is a major abdominal sign for an indication of goreisan, but a stuck feeling in the pit of the stomach presented in some effective cases with goreisan. We concluded that epigastralgia caused by cold foods and drinks with white fur on the tongue and a stuck feeling in the pit of the stomach could be a target for the application for goreisan.

Introduction : We evaluated the efficacy of keishito and maobushisaishinto with reference to keikyososooshinbuto, for patients feeling cold, by means of multiple regression analysis.
Case reports : We reported a patient with an upset stomach whose severe coldness was improved as the stomach condition was cured by adding keishito to maobushisaishinto. Moreover, the combination of keishito and maobushisaishinto was effective for a patient feeling cold, with appetite loss, general fatigue and stiffness of the joints (case 1), a patient feeling cold, with chill, general fatigue, heavy feeling in the stomach, and prone to catch colds (case 2), and a patient feeling extremely cold, with general fatigue and menstrual pain (case 3).
Subjects and Methods : In this study, the subjects were 43 patients who reported feeling cold. They were treated with keishito and maobushisaishinto according to their Sho for more than one month. The relationships between the improvement of cold sensation and 52 other factors, such as symptoms noted at their first medical examination, were evaluated by means of multi-dimensional cross-sectional analysis.
Results : The factors of chilly or unpleasant wind and coldness of the whole body were significant.
Discussion : The factors of coldness in the whole body with chill, and headache without diarrhea were important for improvement of cold feeling with keishito and maobushisaishinto.

The purpose of this report is to clarify urologic problems in rural districts. The number of patients who visited our clinic for these 10 years were 7, 313 as new outpatient and 1802 as inpatient. Three main diseases of rural area were acute inflammation of lower urinary tract, benign prostatic hypertrophy and lithiasis of upper urinary tract. Infection of lower urinary tract and aggravation of malignant tumors might be influenced by rural works and bad circumstances. Monthly distribution of patients was also under the influence of rural works.
