Recent experimental studies and clinical cases have suggested that grafting tissue from the adrenal medulla into the brain may alleviate the symptoms of Parkinson's disease. Autologous adrenal medullary grafts into the striatum was performed stereotactically in two patients with Parkinson's disease. Both patients were bedridden preoperatively, but 4 months after the surgery both became ambulatory and one was even capable of returning to his job. Even though the number of cases was small⑵ and the follow-up period was short, this study shows that adrenal medullary transplantation into the striatum may have some beneficial effects in patient with Parkinson's disease. Further experimental and clinical trials are necessary to see whether this procedure will be a recommendable surgical treatment for patients suffering from Parkinson's disease.

정해관,김수근 大韓産業醫學會 1998 대한직업환경의학회지 Vol.10 No.2

VDT workers are often exposed to static load in the shoulder stabilizing muscle due to repetitive work over long periods. Many investigations were reported the relationships between static load due to repetitive work and regional muscle disorder. However, diagnostic approach to work-related muscle disorder is difficult due to the absence of objective dignostic tools. This study was performed to investigate the relationship between the serum CPK(creatine phosphokinase) concentrations and the shoulder muscle disorders. Results are as follow. 1. Mean serum CPK in total VDT workers was 67.6±28.4 IU/l and workers with abnormal serum CPK were 35(21.5%). 2. Comparison between cases and controls did not show significant difference in the serum CPK level and the distribution of abnormal findings. 3. Sensitivity and sepcificity of the CPK test was 23.0% and 82.0%, respectively. Above results, in accordance with literatures, show that while serum CPK measurement can be useful for the diagnosis of acute muscle injury, it does not adequately reflect the muscle disorders developed by the repetitive work of low tension over long time, such as VDT works.
