Purpose of this study was to examine the recovery process of delayed onset muscle soreness, jump performance, force to contact with the ground and lower limbs movement after intensive jump exercise (IJE), and the relationships between muscle soreness, changes of jump performance and lower limbs movement. Nine males who have experience in special jump exercise participated in this study voluntarily. For the measurement, subjective investigation of the muscle soreness, drop jump performance using a 30 cm high box [jump height, contact time and drop jump index (jump height / contact time)], ground reaction force and movements of lower limbs. This measurement was carried out before IJE (Pre), and at 4 hours (P4), 24 hours (P24) and 72 hours (P72) after IJE. Main results are as follows ; at the time of P24 when intense muscle soreness appeared, significant jump height decreases and contact time increases were shown, and the jump index decreased markedly. This decrease of performance correlated to the change of knee and ankle joint movements during the eccentric phase. At P4, for a subject who felt strong muscle soreness, the decrease of jump height and jump index were considerable. At P72, most subjects recovered to the levels of jump height and contact time to the Pre level. The findings reveal that the jump performances are related to the degree of delayed onset muscle soreness.

Two uremic patients gradually advanced in years were successfully treated with dialysis, even though they had some medical and social problems. The first case was a 97-year-old female, in whom hemodialysis could be introduced because one of her neighbors offered to support her to get the dialysis therapy. The second case was an 87-year-old male. He had rejected dialyis, when he had suffered from pulmonary edema as a complication of uremia. He finally accepted dialysis after his general condition was remarkedly improved by forced hemodialysis. These two cases show difficulty in initiating dialysis in very old patients. A decision not to offer or to discontinue dialysis should be made after sufficient discussion and counselling among the medical staff, patients, and their families, since it is difficult to establish indication criteria for dialysis therapy in such high-aged patients.

Xenon beam wide wave-length including ultraviolet, visible and ultrared rays.
What effects are produced for the human body by using xenon beam effective on the removal of the living body pain?
After patients suffering from low back pain were radiated by xenon beam, their finger-floor distances were measured.
It was examined and compared with the results after using micro wave therapy.
As a result, in xenon beam therapy group, the more the number of times of stimulation was, the shorter the finger-floor distances became gradually, and after more than five times of stimulation, shortening of them was apparent (p<0.01).
Moreover it was known that shortening could be kept in xenon beam therapy group.

Xenon photorays are incoherent waves like the sun rays, but it shows a bright line spectrum. Each bright line exhibits a form similar to the laser spectrum waves. The microwaves have been conventionally used to deliver stimulation to the deep tissues. The effects of the xenon photorays and microwaves on the range of motion in scapulohumeral periarthritis were compared.
Our findings indicated that xenon photorays were superior to the conventional microwaves in bringing about improvement of the range of motion in scapulohumeral arthropathy.
