Results and discussion
Any other information on results incl. tables
- Hemolysis appeared from 10 µM catechol after 24-hr
incubation. At 100 µM, 10% of the red blood cells were
hemolysed. At 1 mM, the hemolysis rate was 70%.
The decrease of ATP content was 90% at 100 µM and ca. 100% at 1 mM.
- At 100 µM, pyrocatechol significantly increased the
activities of MnSOD, peroxidase and glutathione peroxidase.
This stimulation persisted at 10 µM for MnSOD activity.
Catalase activity decreased.
According to the authors, catechol interacts with the production of oxygen radicals. This hypothesis is supported by the fact that during autoxidation of catechol, such free radicals are formed.
