氯化锂对泥鳅胚胎发育的影响

研究了ＬｉＣｌ对泥鳅早期胚胎发育的影响。结果表明，ＬｉＣｌ对卵裂早期至神经胚期的形态发育有明显的致畸作用，不同发育时期的胚胎对ＬｉＣｌ的敏感性不同。ＬｉＣｌ对原肠期胚胎的致畸效应相对较强。

Effects of Lithium on the Embryonic Development of Misgurnus anguillicaudatus

Embryos of Misgureus anguillicaudatus were exposed to 0.4mol/L LiCIfor 5 min at various stages of early development. The result showed that lithium had teratogenic effect on the loach embryos during developmental periods from early cleavagestage to neurula stage. Exposing embryos to lithium at gastrula stage leaded to relativelyhigher proportion of abnormalities than that at other stages. Most of lithium-inducedteratogenic embryos had shortened axial structures, poorly formed eyes and oederna. Ob-servation on the structure of the deficient embryos at the stage of yolk exhaustion indicated that abnormality were also found in liver, notochord, muscle and brain etc.
