[The chemical and radiation effects of uranium solutions on the developing roe of the loach (Misgurnus fossilis L.)].

A study was made of the effect of alpha-radiation of 238U solutions and enriched uranium (9.9 X 10(7) Bq/g) on developing Misgurnus fossilis eggs. The incidence of abnormal larvae and the death rate of eggs increased when the latter were incubated in 138 mg/l solution of uranium 238: this was not accompanied by the increase in the yield of the aberrant ana- and telophases in the epithelium cells of 1-day larvae.
