Experimental Study on Developmental Toxicity of AlCl_3 to Rats' Embryo in Vitro / 环境与健康杂志

ABSTRACT

re To understand the developmental toxicity of aluminum and its mechanism. Methods The embryos of SD rats at the 9. 5th day after gestation were explanted and cultured in a whole-embryo culture system with exposure to AlCl3 at Al3+ concentrations of 0.6, 0.9, 1.2, 3.0, 6.0 and 9.0 ?g/ml for 48 hours. Using Brown's mor-phological scoring system, yolk sac diameter, crown-rump length, head length and embryonic dry weight were mea-sured. Results A certain dose-effect relationship (r= - 0.890? 0.973, P
