摘    要:观察了 40例不同胎龄胎儿胃底部两型肥大细胞发育、数量及分布和胃底部发育的关系 ,并探讨了甲醛固定对 CTMC和 MMC染色效应的影响。发现人胎儿胃 CTMC出现于受精后 13~ 16周的粘膜下层等处 ,主要分布在胃粘膜固有层近粘膜肌处 ,数量随粘膜层胃底腺及粘膜肌等结构的发育而增加。两型肥大细胞对甲醛固定的反应无明显差异。本文就肥大细胞在胃底部发育过程中的意义进行了讨论

关 键 词:人胎胃  肥大细胞

Abstract:The relationship of development, number and distribution of two types of mast cells with development of human fetal stomach fundus was investigated by light microscopy in 40 cases of human fetal stomach samples. And the influence of FA fixation on mast cell staining was also researched. The results indicated that the first appearance of CTMC in the submucosa of the fetal stomach could be traced to the stage of 13-16W after fertilization, and they were mainly distributed around the small blood vessels in the submucosa. Appearance of MMC was in 17W after fertilization and predominated in the lamina propria close to the muscularis mucosae and the number was increased with the development of the fundic gland and muscularis mucosae. No difference was found in the effects of formaldehyde fixation on both types of mast cells. The significance of mast cells in the development of human fetal stomach was discussed.
Keywords:human fetal stomachs mast cell
