title: [Epidemiological interventional study on controlling endemic arsenism].
abstract: Residents exposed to high arsenical water in Kuitum area of Xinjiang Autonomous Region were studied by on the spot interventional trial experiment. After ridding arsenic from drinking water, 82.43% of chronic arsenism were either cured or showed improvements of health conditions and no new' cases of arsenism developed during the experiment. The values of arsenic in patiens hair and urine decreased by drinking water free of arsenic, but remained higher than those of normal residents. Our results showed that drinking normal water could help to progressively eliminate arsenic storage from the chronic arsenism. By means of electromyograph (EMG), we found that the nerve conduction velocities of patients increased significantly (P less than 0.01) and that -SH reactivities of peripheral blood corpuscles of patients recovered to the normal level.
