[Toxicity of ochratoxin A. 3. Effects during the initial stages of pregnancy in the rat].

Ochratoxin A administered by gastric tubing to pregnant rats at day 2 after mating increases the number of resorbtion sites. A high level of mycotoxin was found in the plasma of females and in the embryos (up to 5.6 p. cent of the total administered doses). At sacrifice time (day 10 after mating) no morphological defect was observed in the embryos.
