[The toxicity of a prometryne/simazine combination in the lactation stage of rats].

The postnatal effect of a combination of Prometryne and Simazine was analyzed in rats. Lactating rats were administered from 5 through 10 d pp. The effect on rat pups were characterized by reflex development, behavioural toxicological tests, and selected biochemical investigations. Distinct effects were observed on body weight, neuro-muscular maturation, and somatic development. There were also significant differences in the content of C-reactive protein and the number of white blood cells.
