利用垂体泌乳素细胞腺瘤30例的手术切除的瘤组织,做了电镜检查和免疫细胞化学的检查,在电镜下可分为多分泌颗粒PRL细胞腺瘤和少分泌颗粒PRL细胞腺瘤以及二者的混合。用免疫细胞化学染PRL,少分泌颗粒的PRL细胞有特点:PRL阳性物质大都呈一边界清楚的团块,其中有棕黄色的颗粒,它们的大小、形状变异大,但都位于核的一侧,在核有凹陷而且胞浆多的一侧。这个PRL阳性团块相当于电镜下的泌乳素小体。瘤细胞内PRL阳性物质少甚或阴性的
Utilizing surgically resected tumor tissue from 30 cases of pituitary prolactin adenoma, electron microscopy and immunocytochemistry were performed. Under electron microscope, multiple secretory granules PRL cell adenoma and secretory granules PRL cell adenoma and two The mix. Immunocytochemistry stains PRL. PRL cells with less secretory granules are characterized by the fact that most PRL-positive substances are presented with well-defined lumps, brown-yellow granules, which vary greatly in size and shape, but are located on the side of the nucleus. , on the side of the nucleus with depression and cytoplasm. This PRL-positive mass corresponds to electron microscopic prolactin bodies. Less or even negative PRL-positive substances in tumor cells
