摘要

对人胚胎发育第5周(第15期)的脑膜脑疝进行了研究。顶骨疝的分析表明,脑组织的异常发育与神经管的成形过程紊乱有关。神经板发育阶段髓质环未闭合,形成游离边缘的神经上皮层。它的松弛导致神经上皮细胞的自发折叠和增殖增强。增生活动导致脑层端区增生,脑的不成比例的快速生长破坏了头外胚层的完整性,引起脑外疝的形成。结果表明,控制神经上皮增殖活性的切向机械张力的干扰是神经组织过度生长的基础。

[The effect of a parietal meningoencephalocele on the morphogenesis of the neuroepithelium of the human brain].

Meningoencephalic hernia was studied in human embryo at the 5th week (stage 15) of the development. The analysis of parietal hernia showed that the anomalous development of cerebral tissue was related with disturbed shape-forming processes in the nerve tube. The medullar toruli were not closed at the stage of nerve plate to form a free edge of neuroepithelial layer. Its relaxation resulted in a spontaneous foldness and an enhanced proliferation of neuroepithelial cells. The proliferative activity induced hyperplasia of the layer end zones a disproportionately rapid growth of the brain disturbed the integrity of cephalic ectoderm and elicited formation of external cerebral hernias. It was suggested that disturbances of tangential mechanical tensions which control the proliferative activity in the neuroepithelium underlie the overgrowth of nervous tissue.
