本文报导了用免疫细胞化学PAP方法,对小鼠三个时期(胎期、新生期、成熟期)的胃、十二指肠、胰腺中D细胞进行的初步观察。结果发现在三个不同时期上述器官中D细胞在数量及分布上都有一定的差别。胎期胃幽门中一般未见D细胞,但十二指肠和胰腺中已可见。出生后胃幽门D细胞逐渐增多,而十二指肠D细胞相对略有减少 This article reports the initial observation of D cells in the stomach, duodenum and pancreas of mice in three stages (fetal, neonatal, and mature) by the immunocytochemical PAP method. The results showed that there were some differences in the number and distribution of D cells in these organs in three different periods. Fetal stomach Pylorus generally do not see D cells, but the duodenum and pancreas have been seen. After birth, pyloric D cells gradually increased, while duodenal D cells were relatively slightly reduced
