摘要
本文对大鼠、牛、猪和羊的附睾组织,取其头、体和尾三段,用PAS等方法染色,作光镜观察。发现这些动物的附睾上皮中,夹有一种富有PAS阳性颗粒的细胞,颗粒内含中性多糖,其分泌方式为顶浆分泌。HE染色中的亮细胞,可能是分泌颗粒排出后的PAS阳性细胞。此外,在输精管起始段的上皮中,亦偶见有这种PAS阳性颗粒细胞。
This paper reports the histological observation on PAS-positive granular cells in epididymal epithelium from rat,bull,swine and ram.Caput,corpus and cauda of epididymis from these animals(10~14 for each species)were taken,routine fixed and embeded,6μm section,PAS stained and observed under light microscope.There is a kind of PAS positive granular cell existed in epithelium of all segments of epididymis from all these animals.These PAS positive granules are proved to be neutral polysaccharide and an apocrine secretion pattern is suggested.The so-called clear cell in HE stained slides might be PAS-positive granular cell which has already discharged its contents.Besides,this kind of cells are occasionally located in the vas deferens as well.
