Abstract/OtherAbstract:
The incidence of sea urchin embryos developing abnormally after their exposure to equimolar concentrations of halothane, enflurane, and methoxyflurane has been determined. Halothane concentrations in the 0.6-1.25 mM range caused 18-96% of the embryos to undergo abnormal cleavage at the first cell division. This is important because embryos exhibiting atypical cleavage patterns at the first cell division eventually involute and die before reaching gastrulation. Over the same range of concentrations, enflurane and methoxyflurane have minimal effects on development. However, when exposed to 2.5 mM methoxyflurane, nearly 40% of the cells did not fertilize. These results show that volatile anesthetic agents have decidedly different effects on development and suggest that the incidence of abnormal development may not correlate directly with the anesthetic potency of inhalational agents.
