[Effect of bacterial preparations on the survival of irradiated animals].

A comparison of therapeutic effects of bacterial preparations (vaccinum dysenteriae, colibacterinum, bifidumbacterinum, bificolum) after gamma-irradiation was carried out. Bificolum showed the maximum and bifidumbacterinum the minimum effect, while colibacterianum had a therapeutic effect only within a narrow range of doses. Vaccinum dysenteriae was also effective.

[The transplacental transfer of nitrates and their effect on the human fetus].

Nitrates entering the body of pregnant woman with food and potable water were showed to pass through the placental barrier and get into fetus. Transplacental transfer of nitrates under condition of nitrate overload on the body may result in development of hemic hypoxia, deterioration of biophysical profile of fetus and subsequently compromised infant's condition estimated by Apgar scale.
