Development of explanted rat fetuses in hyperbaric oxygen

摘要: Raising the oxygen pressure of culture chamber to 2 or 3 atmospheres improved development in static serum rat embryos explanted at 11.5 days' gestation, but final stage attained (35–37 somites) was less than that circulating equilibrated with normal (40–45 somites). Hyperbaric appeared be most value for 12.5 gestation (about 40 These developed well 50–55 somites two pressure, showed very little pressure. The high concentrations were harmful yolk sac, and it not possible extend beyond somites.
