[Chemiluminescence activated by rhodamine G in plasma in the presence of divalent iron ions].

Rhodamine G was found to activate blood plasma chemiluminescence induced by ferrous ions. The dye in concentrations 300-500 mole/l increased chemiluminescence by an order of magnitude. The luminescence was inhibited by histidine and SOD. A conclusion may be drawn that the mechanism of the activated ferrous chemiluminescence with rhodamine G was related to superoxide anion-radicals and singlet oxygen.
