[The mechanisms of the antiherpetic action of aqueous propolis extracts. I. The antioxidant action on human fibroblast cultures].

A redox state modulation model was worked out in human fibroblast cultures treated with oxidation stress inducing agents and a redox agent, virtually protecting cell against the stress. Quantification of the global redox changes in fibroblasts was done using the hemoglobin electronic spectrum, in the presence and in the absence of H2O2.
