详细

目的:妊娠期暴露于甲醛(FA)的雌性新生大鼠胸腺结构的研究。

材料与方法:这项研究是对72只出生后第一天发育的白杂种大鼠进行的。第一组由幼鼠(n=37)组成,其是6只大鼠的后代,在整个妊娠期暴露于2.766 mg/m3的甲醛中。每天1次,在一平方米的种子室中进行60分钟的甲醛暴露。第二组包括对照动物(n=35)6只大鼠的后代,其在实验过程中均在与实验组相似的条件下进行,除了甲醛的作用以外。测定新生大鼠体重、胸腺绝对质量和相对质量。在光学水平上研究胸腺的结构。在2500µm2的面积上进行了胸腺皮层和大脑物质中的细胞数量计算。

结果:第一组新生大鼠的体重和胸腺绝对质量明显低于对照组的数值。比较组相对胸腺质量值之间的差异不显著。在甲醛作用下胸腺皮层和脑内物质细胞数无明显变化。

结论:甲醛在整个妊娠期对妊娠大鼠身体的吸入作用导致新生大鼠体重和胸腺绝对质量下降。与此同时,胸腺的相对质量没有发生明显变化。胸腺的结构在光学水平上在甲醛的作用下也没有发生显著的变化。
