应用体视学方法对３４例不同月龄的人工引产胎儿及死胎胃标本进行胃腺壁细胞定量研究，结果显示胎儿胃腺壁细胞体密度（Ｖｖ）、表面积密度（Ｓｖ）、数密度（Ｎｖ）均随着胎儿的发育而增加．核体密度（Ｖｖｍ．ｃ）则随着胎儿发育而变小．
Quantitative study of gastric gland parietal cells in 34 fetuses of fetus and fetus with different birthdays at different months of age by stereological method showed that the density of Vv, Sv and Nv With the development of the fetus increased. Nucleosome density (Vvm.c) decreases with fetal development.
