    The purpose of this investigation is to quantify body composition and cardiorespiratory fitness in 46 junior male long distance runners and to evaluate the effects of these factors on running performance. Total and regional body composition were measured using dual energy X-ray absorptiometry. Maximal oxygen uptake (VO2max), ventilatory compensation point (VCP), and ventilatory threshold (VT) were determined during the maximal exercise test using a bicycle ergometer.
    Subjects were classified into two groups. The 5000m running times of 18 subjects in group I were less than 15min, and those of 28 subjects in group II were more than 15min. % Fat of the legs in group I was significantly decreased compared to that of group II. VCP and VT of group I were significantly higher than those of group II, while VO2max was not significantly different between the two groups. VO2max, VCP, and VT were negatively correlated to running times, while the parameters of body composition were not correlated. The increase in VCP alone contributed to running time shown by multiple regression analysis.
    These data showed that VCP is a sensitive predictor of running performance in junior male long distance runners during development.

    Forty-three patients with stage II squamous cell carcinoma of the uterine cervix were treated with intra-arterial cis-platinum before radical hysterectomy. The dose of cis-platinum was 50mg/m2 and the infusion was repeated twice at 3-week intervals. In this investigation, serial colposcopy and biopsies were performed to assess the efficacy of this chemotherapy. On colposcopy, the first change on the surface of the lesion during chemotherapy was a whitish change, followed by a yellowish change. After that, the lesion became less irregular, atypical vessels were less numerous and the surface was covered with squamous epithelium. On pathological examination of the resected materials following radical hysterectomy, viable tumor cells had disappeared in 7 (group 1) and remained in 36 (group 2) patients.
    Retrospective investigation revealed a significant difference in colposcopic findings between groups 1 and 2, one week after the first chemotherapy. In regard to the remaining viable tumor cells, the pathological examination using serial biopsies revealed a significant difference between groups 1 and 2, 5 weeks after the first chemotherapy. Thus, the present results indicate that colposcopy is clinically effective in the early evaluation of the efficacy of intra-arterial injection on uterine cervical carcinoma.

    To prepare for the problems associated with a rapidly aging society, a checkup for the bone mineral density has been performed in many cities and villages in Japan.
    However, there are varying methods for measuring bone mineral density, and the usefulness of quantitative Ultrasound imaging has not been established.
    The relationship between bone mineral density and life style in 627 women in 5 cities was investigated using quantitative ultrasound imaging to measure bone mineral density.
    The results can be summarized as follows:
    1. The results from quantitative ultrasound imaging can be applied to the established DXA method because there was a correlation among dual energy X-ray absorptiometry, single energy X-ray absorptiometry and quantitative ultrasound imaging.
    2. The stiffness index by quantitative ultrasound imaging was highly correlated with age and decreased proportionally with an increase in age.
    3. We suggest that the measurement of bone mineral density by quantitative ultrasound imaging for women at the age of 55 and 60 years in addition to those of 40 and 50 years is necessary.
    4. We speculate that exercise and calcium intake during youth have some effects on bone mineral density of women after the prime of life.

    This study was designed to clarify what factors influenced the ability to stop smoking in male smokers, from the viewpoint of life-style guidance and primary care. Of the people who attended adult health examinations between 1993 and 1998 in Okayama City, 987 male smokers were selected and categorized according to the number of cigarettes per day into three groups. The relation was analyzed statistically between the three groups and the life-style related factors: age, the degree of obesity, sleep, snacks, salt, exercise and alcohol. The results showed significant differences in age, the degree of obesity, sleep, salt, exercise.
    Second, the relation between these three groups and the experience and duration of smoking cessation was analyzed. The results showed a significant difference in the experience of smoking cessation, but no significant difference in duration of smoking cessation.
    The conclusions are as follows:
    1. Male smokers, who do not actively try to improve of their life-style related factors, have fewer experiences of smoking cessation.
    2. Male smokers who try to improve their life-style habits have a similar period of smoking cessation to those who do not.
    3. Long term support for all male smokers to continue to be non-smoking is important.

  • Estimation by MRI of tumor volume is useful to evaluate the extrauterine progress in squamous cell carcinoma of the uterine cervix

    Tumor volume was estimated prior to surgery according to the T2-weighted magnetic resonance imaging (MRI) in 40 cases of cervical cancer. Tumorous space was calculated from the picture on the computer image imported from MRI films. Total volume of the cancer mass was then calculated by integration of the space in regard to the slice diameter. Tumor contour was positively portrayed and total volume was estimated in 30 out of 40 cases. Twenty-two of 23 cases (95.7%) with a volume over 3000 mm3 were revealed to have parametrial invasion and/or pelvic lymph node metastasis. None of 4 cases with a volume less than 1000 mm3 and 10 cases in which no tumor was exhibited were revealed to have any extrauterine progress.
    These results suggest that the estimation of tumor volume using this method is useful to predict extrautrine progress prior to surgery, and would be useful in planning cervical cancer therapy.

    Our breast quadrantectomy operative procedure and the clinical results are reported. We have performed this method in 19 patients with stage I and II breast cancer under general anesthesia. A negative margin of cancer was confirmed by intraoperative histological examination. Our method of quadrantectomy was performed without suturing both cut edges, which allowed interstitial fluid to collect. Of nineteen patients operated using this method, 17 were satisfied with the cosmetic results. Burn and infection were the causes of deformity of the preserved breast. Tight adaptation of the skin suture, avoiding burns due to electrocautery and suturing of the residual duct are recommended procedures for satisfactory results.

    We performed a breast conservation operation in 5 patients using a clinical pathway in 1995 and analyzed the effect on the patient's outcome. Compared to 5 patients without a clinical pathway during the same time period, the mean hospital stay decreased from 10.8 to 4.6 days and the amount of antibiotics decreased from 9.0 to 2.0g. A satisfactory effect was observed on the establishment of communication between staff and the standardized care of patients. Breast conservation operation seems to be a good candidate for the introduction of a clinical pathway. Further improvement could be obtained by reviewing the outcome of patients.
