Abstract:

Objective: To investigate the protective effect of Opuntia milpa alta polysaccharides (OMAP) on human red blood cell (RBC) membrane and mouse hepatocyte DNA damage induced by sodium dodecyl sulfate (SDS). Methods: RBC hemolysis test and Comet assay were used to determine the effect of OMAP on cell membrane damage and DNA damage, respectively. Three groups were designed for the experiments. The positive control group of cell system was given 40μg/mL SDS; OMAP control groups of cell system were cultured in media containing OMAP with varying concentrations (20, 40, 60, 80 μg/mL and 100μg/mL); OMAP + SDS groups of cell system were first treated with OMAP at varying concentrations prior to incubation in media with 40 μg/mL SDS. Results: OMAP presence at all concentration conditions could markedly prevent cell membrane and DNA damage induced by SDS, and an obvious dosage-response relationship was observed. Conclusion: OMAP has good potential to protect SDS-induced cell membrane and DNA damage.
