Materials and methods

Test guideline
Qualifier:
no guideline available
Principles of method if other than guideline:
Various dosages of Sodium Erythorbate were administered via gastric intubation to mated female albino CD-1 outbred mice on days 6-15 of gestation. The test volume was 10ml/kg in water. The positive control was 150mg/kg of aspirin. Body weights were recorded on days 0, 6, 11, 15, and 17 of gestation. The mice were observed for apperance and behavior, as well as feed consumption.

Examinations

Maternal examinations:
All control and test mice survived to term. Of the nagative control mice, 21 of 30 became pregnant. Tweny-one of 23 mice of the positive control
group were pregnant.
Fetal examinations:
Average fetus weight doesn't change. Live fetuses examined at term. The number of abnormalities seen in either soft or skeletal tissues of the test
groups did not differ from the number occurring spontaneously in the sham-treated controls.
