几种畸形胎儿肾上腺的组织学观察

The Histological Observation and Analysis of Several Malformation Fetus Suprarenal Gland

目的:探讨三种畸形胎儿肾上腺发育及组织学特征。方法:解剖观察肾上腺、整体取材、常规HE染色、光学显微镜观察肾上腺组织学结构。结果:无脑儿肾上腺未发育(缺如);胸腹壁联体畸形胎儿肾上腺发育欠充分;并(缺)指畸形胎儿肾上腺发育正常。结论:无脑儿因脑垂体、神经系统发育障碍,而致肾上腺不发育;联体畸形胎儿肾上腺发育较同龄正常胎儿迟缓。

Objective：To discuss the development and histological character of 3 malformation fetus suprarenal gland. Method：To dissect and observe the suprarenal gland, to draw materials from the organ in whole, then suprarenal gland tissue slices under the light microscope with methods of HE. Result：Undevelopment of the anencephalus （without development）. Thoracogastrodidymus develops defectively. Ectrosyndactylia develops normally. Conclusion ： To anencephalus the hypophysis and nervous system develop defectively result in undevelopment of su-prarenal gland. Thoracogastrodidymus develops more slowly than normal fetus.
