本研究应用电镜及免疫电镜技术对 2 1 8例垂体腺瘤进行了观察分析 ;并根据瘤细胞超微结构及免疫细胞化学反应特点进行了分类。免疫电镜证实并非所有含纤维小体的瘤细胞为生长激素细胞 ,某些泌乳素细胞腺瘤亦可查见纤维小体 ,这提示纤维小体并不是垂体生长激素腺瘤特有的一个形?
In this study, electron microscopy and immunoelectron microscopy were used to observe and analyze 218 cases of pituitary adenomas. The classification was based on the ultrastructure of tumor cells and the characteristics of immunocytochemical reactions. Immunoelectron microscopy confirmed that not all tumor cells containing fibrous bodies are growth hormone cells. Some prolactinomas can also be found in fibrous bodies, suggesting that the fibrous body is not a unique form of pituitary growth hormone adenoma.
