One of the studies reported signs of improved immunological defense and a lower number of infection days among those who received antioxidant supplements.
There has been increasing interest in clinical trials of antioxidants toward prevention or treatment of preeclampsia.
The antioxidant glutathione is of the essence for all life forms discussed here.
At low concentration exogenous hydrogen peroxide induced an adaptive response of cells by promotion of synthesis of antioxidant enzymes and heat shock proteins.
Its further decrease may be due to the intensive use of antioxidants in the period of high infection level and greatest production of free radicals.
Indirect evidence of increased free radical activity (oxidative stress) may be obtained by measurement of antioxidant concentrations in all tissue and body fluids.
The pecking order of free radicals and antioxidants: lipid peroxidation, a-tocopherol and ascorbate.
Changes in antioxidant compounds or enzymes during seed development should also be regarded as a prerequisite for obtaining a vigorous seed.
