[Effect of small concentrations of carbon disulfide and hydrogen sulfide on the intrauterine development of rats].

Under study were small concentrations of carbon bisulphide and hydrogen sulphide on embryonic development of rats in a natural experiment (under conditions of viscose industry). Prolonged exposure to the agents gives an embryotoxic effect at the pre- and postimplantation stages and they are responsible for the appearance of abnormalities of predominantly genito-urinary and bone systems in a small amount of embryos, disturb embryonal blood formation and the ossification process, result in severe changes of the parenchymatous cells of the liver and kidneys of rat embryos.
