[Studies on generation and inhibition of active oxygen in alveolar macrophage by chrysolite and aluminum citrate].
Chrysolite-induced generation and aluminum citrate-induced inhibition of active oxygen in alveolar macrophage were studied with ESR spin-trapping technique, cytochrome C reduction and phenol red oxidation assays. Results showed, under certain conditions, Mangya and Laiyuan chrysolite fiber could stimulate macrophage to generate OH., O2-. and H2O2 in a dose-dependent manner. But such an induced-generation of active oxygen would be inhibited by the treatment of chrysolite with aluminum citrate solution at room temperature for one hour.
