Health Survey (SF-36) for use in health related quality of life measurements for Korean elderly people. SF-36 data from 90 healthy elderly people using Social Education Service and 120 elderly patients using a day care service in Seoul, Korea, were examined. We translated SF-36 version 2.0 into Korean and assessed its reliability and validity. In the results, the content validity and discriminant validity were found to be satisfactory. Cronbach's α coefficients ranged from 0.9298 to 0.9383. The test-retest reliability coefficients ranged from 0.710 to 0.895. In addition, the utility was examined by testing the correlation between the health-related QOL and related factors (sex, age, motor function, ability of daily life) among the elderly people. The present findings suggested that the Korean version of SF-36 would be useful as a measure of the health related QOL in Korean elderly people.SF-36; Korea; health-related quality of life; stroke

We studied the possible role of melatonin deficiency in experimentally-induced scoliosis. A total of 90 chickens underwent pinealectomy on the third day after hatching: 30 were treated with serotonin, 30 with melatonin and 30 received no therapy (control group). Scoliosis developed in all the control group, in 22 of the serotonin group, and in only 6 of the melatonin group. The six melatonin-treated chickens with scoliosis had less severe spinal deformities than those in the serotonin-treated group. There were lower blood melatonin concentrations in chickens with scoliosis than in those without. Our findings suggest that melatonin deficiency contributes to the aetiology of this experimental scoliosis, probably by interfering with the normally symmetrical growth of the proprioceptive system involving the paraspinal muscles and the spine.
