Results and discussion

Applicant's summary and conclusion

Conclusions:
Sodium azide has a drastically toxic effect on the in vitro growth of mouse embryos at concentrations of 10^(-4) mol/L in the petri dish or greater.
Executive summary:

The toxicity potential of sodium azide on mouse development was determined in vitro. Embryos were treated with sodium azide and evaluated following 72 hours of culture. The results show that sodium azide has a drastically toxic effect on the in vitro growth of mouse embryos at concentrations of 10 -4 mol/L in the petri dish or greater. It was toxic to most, though not all, mouse embryos at 10 -5 mol/L but was not significantly toxic at levels of 10 -6 mol/L or less.


The study does not follow any guideline and is not GLP compliant. Moreover, further details are not available for this study and documentaion is insufficient for assessment.
