摘要
目的 探讨用组织化学方法鉴别血吸虫体外培养细胞来源或种类的可能性。 方法 取日本血吸虫肝期童虫 ,经酶消化处理后取混合细胞涂片 ,用成虫制作组织切片。将细胞涂片和组织切片分别平行作高碘酸 希夫氏(PAS)、硫堇 (Thionin)、嗜银反应 (根据Grimeliu s)、苦味酸 酸性品红 (根据VanGieson ,VG)、甲苯胺蓝 (Tolui dineblue ,TB)和苏木素 伊红 (HE) 6种组织化学方法染色。光镜下比较观察 ,判定结果。 结果 PAS染色的大细胞呈亮红色与组织切片中卵黄腺着色接近 ,表明着色的大细胞来源于卵黄腺 ;含特有尼氏体的神经细胞胞浆被硫堇染色呈深蓝色 ;Grimeliu s染色的细胞和消化道上皮细胞均呈黑色 ;VG染色 ,部分细胞和虫体肌纤维组织均呈黄色 ;TB染色 ,细胞涂片仅见 1个紫红色细胞 ,组织切片未见相同颜色的组织和细胞。 结论 PAS、硫堇、Grimeliu s、VG、TB和HE 6种组织化学染色 ,对体外培养的血吸虫细胞的显色特征与虫体相应器官或组织细胞的化学染色定位相一致。本法可用于鉴别血吸虫体外培养细胞的来源或种类 ,且操作简便、快速。
Objective To study the possibility on in vitro identifying the source or kinds of cells from Schistosoma japonicum(S.j). Methods\The cells from digested tissues of 18 days old schistosomula were smeared on slides. The adult worms of S.j were used for making paraffin sections. The cell smears and tissue sections were stained with 6 different methods of histochemical staining including Periodic Acid\|Schiff (PAS), Argyrophil reaction (by Grimeliu's), Picric acid\|acid Fuchsin (by Van Gieson,VG), Thionin, Toluidine blue (TB) and Hematoxylin\|Eosin (HE) staining parallelly. The results were judged through inspecting the specific color of the cells on smears referring to location of corresponding staining of paraffin sections of adult worm tissues under light microscopy. \ Results \ Vitelline gland cells, mother germ cells, nerve cells, digestive epithelial cells, muscular cells and mast cells were shown clearly. The stainings of VG, PAS and Thionin demonstrated cell types coinciding to histological location. The TB staining did not find red\|purple mast cell in tissue sections but one in cell smears. The Grimeliu's argyrophil reaction displayed that intestine wall of tissure sections and stained cells of cell smears were in black clearly. \ Conclusion \ HE staining together with histochemical staining can reliably and rapidly distinguish the cell types of Schistosoma japonicum.
