Ogawa K., J. Oka, J. Yamakawa, and M. Higuchi. A single bout of exercise influences natural killer cells in elderly women, especially those who are habitually active. J. Strength Cond. Res. 19(1):45-40. 2005.--The purpose of our study was to examine the effects of a single exercise bout on the natural killer (NK) cell count and activity in physically active elderly people, sedentary elderly people, and sedentary young people. Eight elderly women who trained by walking (age, 64 [+ or -] 1 years; [Vo.sub.2peak], 32.2 [+ or -] 1.1 ml*[kg.sup.-1]*[min.sup.-1]), 8 age-matched untrained women (63 [+ or -] 1 years, 28.8 [+ or -] 1.0 ml*[kg.sup.-1]*[min.sup.-1]), and 8 young untrained women (25 [+ or -] 1 years, 37.6 [+ or -] 1.6 ml*[kg.sup.-1]*[min.sup.-1]) were studied. Blood samples were taken before, immediately after, and 2 hours after a 30-minute bout of exercise at an intensity equivalent to 70-75% of [Vo.sub.2peak]. Peripheral blood mononuclear cells were isolated and the NK cell count and activity were analyzed. The NK cell count of the elderly sedentary group immediately after exercise was significantly higher than those of the elderly women who walked and young sedentary women, whereas no significant interaction was detected in NK cell activity and NK cell activity per cell number among the 3 groups. Consequently, an intrinsic defect in the cytotoxic ability of NK cells appeared in sedentary elderly people but not in active elderly people who perform habitual exercise.

Abstract

This study was to assess the effect of a fixed dietary intake on biomarkers of red blood cell (RBC) biosynthesis and degradation. Over a two-year period, eight collegiate rhythmic gymnasts participated in this study. During the first year, they ate self-selected diets. During the second year, a fixed dietary intake involving consumption of common Japanese foods containing 15 mg iron and 1500 kcal energy was maintained for 4 wk at the beginning of the program. Fixed dietary intakes resulted in significantly increased intakes of protein, minerals and vitamins, and significantly decreased fat intake, but total energy and carbohydrate intakes were unchanged. Mean values of RBC, Hb, Ht, or TIBC were not affected by the intervention. A fixed dietary intervention appeared to enhance RBC turnover by increasing the capacity for erythrocyte biosynthesis and degradation, although the prevalence of iron-deficiency anemia remained unchanged.

Abstract

Nonaphenylenes and dodecaphenylenes are prepared by using electron-transfer oxidation of Lipshutz cuprates with duroquinone. The formation of nanostructures from oligophenylenes is studied and the maximum fluorescence intensity is obtained in the direction perpendicular to the longitudinal axis of the fiber, showing the stacking direction to be parallel to the longitudinal axis of the fiber.

Abstract

The current standard treatment for cancer is a multidisciplinary therapy whereby various types of treatment are properly combined. Chemotherapy with multiple anticancer drugs is now common, and traditional, complementary, and alternative therapies are adopted as supportive measures. Medical care in Japan is distinguished by the ability for patients to access both Western and Kampo medical cares at the same time. There is a high degree of trust in the safety of Kampo therapies because they are practiced by medical doctors who are educated with fundamental diagnosis of Western medicine. Highly reliable clinical studies are being published, demonstrating that palliative or supportive care for cancer patients using Kampo preparations alleviates adverse effects of chemotherapy or radiotherapy. This paper reports the circumstances around cancer care in Japan where traditional therapeutic Kampo formulas are used for patients undergoing cancer treatment with cutting-edge chemotherapy, specifically to alleviate adverse effects of anticancer drugs.

Abstract

The cause of obesity includes genetic and environmental factors, including cytokines derived from adipocytes (adipo-cytokines). Although drug therapy is available for obesity, it is highly risky. Our main focus in this review is on the traditional form of Japanese medicine, Kampo, in the treated of obesity. Two Kampo formulas, that is, bofutsushosan (防風通聖散) and boiogito (防己黄耆湯), are covered by the national health insurance in Japan for the treatment of obesity. Various issues related to their action mechanisms remain unsolved. Considering these, we described the results of basic experiments and presented clinical evidence and case reports on osteoarthritis as examples of clinical application of their two Kampo medicine. Traditional medicine is used not only for treatment but also for prevention. In clinical practice, it is of great importance to prove the efficacy of combinations of traditional medicine and Western medicine and the utility of traditional medicine in the attenuation of adverse effects of Western medicine.

Abstract

Clinical trials to date demonstrate that standard cancer treatments are currently the most efficient treatments for large numbers of cancer patients. Cancer treatments will increasingly require approaches that allow patients to live with cancer, by increasing their natural healing power and tumor immunity, as well as attenuating the progression of their cancers, instead of only attacking the cancer cells directly. Complementary and alternative medicine, including Kampo medicine, compensates for the drawbacks of western medicine by increasing patients’ self-defense mechanisms. In Japan, clinicians who have studied both western medicine and Kampo treat cancer patients by fusing the two medical systems into a unitary one. The goal of the system is to assist the functional maintenance and recovery of the living body complex with the physical, mental, social, and spiritual balance, rather than addressing direct antitumor effects. In this review, we describe the usefulness of Kampo medicine, especially juzentaihoto, and outline the reports on evidence, in addition to the report on an attitudinal survey about the use of Kampo medicine in cancer treatment in Japan.
