[Glutathione in the blood and dehydrogenase activity in the serum of workers engaged in the manufacture of divinyl (1,3-butadiene)].

Examinations were carried out on 75 workers engaged in the production of divinyl, in order to evaluate the detoxifying and carbohydrate function of the liver. A significant statistic decrease of glutathione in blood was established, which gave grounds to propose this index as early criterium for the toxic effect of divinyl. A decrease in the dehydrogenase activity in the serum of workers was established. These changes were accepted as non-specific. The highest professional risk is evident with the technological staff.
