Nа+, K+-ATPase activity of loach embryos membranes during early embryogenesis under the influence of sodium hypochlorite

Abstract

The paper contains data regarding the influence of sodium hypochlorite on the activity of embryos membrane Na+, K+-ATP-ase of loach Misgurnus fossilis L. in early stages of the development. We showed that sodium hypochlorite added to the medium where the embryos develop, caused dose-dependent inhibition of the membranes Na+, K+-ATP-ase activity. We suggested that effects of sodium hypochlorite were due to oxidizing properties and its ability to disrupt membrane integrity, in particular, damaging proteins and lipids.
