摘要:

目的 对比高碘酸-雪夫(Periodic acid-Schiff,PAS)与双花扁豆凝集素(Dolichos Bifows Agglutinin,DBA)组织化学法所显示的小鼠蜕膜自然杀伤 (decidual natural killer,dNK) 细胞的不同。方法 取妊娠第3~19天小鼠子宫,制备成连续的切片,分别经PAS、DBA组织化学法、DBA加PAS双重反应显示dNK细胞。结果 典型的 dNK细胞含有PAS阳性颗粒,其胞膜、核膜和颗粒膜与DBA特异性结合而呈阳性反应;妊娠早期(妊娠第3~6天)不含颗粒的幼稚dNK细胞也可以被DBA标记。DBA加PAS双重反应时,含颗粒的dNK细胞大部分可以被同时标记。结论 DBA是dNK细胞的一种新的标志物,在妊娠早期可用以显示 PAS阳性颗粒尚未出现的幼稚dNK细胞。

Abstract:

To identify the difference of mouse decidual natural killer (dNK) cells reacting to Periodic Acid Schiff's (PAS) and Dolichos Biflorus agglutinin (DBA). Methods The dNK cells of mice uteri Gd 3 to Gd 19 (using the copulation plug as Gd1) were shown on continuous paraffin sections by PAS, DBA, PAS/DBA double reactions protocol. Results Typical dNK cells contained numerous PAS positive reactive cytoplasmic granules. The cytoplasmic membrane, nuclear membrane and granule membrane of dNK were positive reaction to DBA due to their specific binding. The immature dNK cells in the uterus of early pregnancy (on Gd 3 to Gd 6) were negative to PAS because of their absence of granules. Majority of dNK cells could be labeled at the same time with DBA plus PAS double staining. Conclusion DBA can be used as a new marker to show dNK due to its specific binding to membranes. DBA has advantage especially in early pregnancy (such as on particles Gd 3) because PAS positive granules have not yet appeared in immature dNK cells.
