[On molecular biology of ageing. 12th communication. Glutathione, SH-reagents, metabolism (author's transl)].

1. The significantion of the regulative function of SH-groups in ageing is described comprehensively 2. The redox state of glutathione changes in ageing 3. The activity of SH-enzymes is decreased in old tissues. They are reactivated in vivo and in vitro 4. The decreased protein synthesis in the liver of old rats is stimulated by 2-mercaptoethanol.
