Evaluation of the biological properties of a highly efficient tissue cell preservative

目的探讨新型高性能、绿色环保组织细胞保存材料对胸腹水细胞形态和性状保存的价值,评价其生物学性能。方法应用常规HE染色和Western blotting分别检测经新型高性能、绿色环保组织细胞保存材料和95%乙醇常规固定液固定保存的56例胸腹腔积液组织细胞CK、CEA和P53的形态学特点和蛋白表达水平。结果经新型高性能、绿色环保组织细胞保存材料固定保存的胸腹腔积液组织细胞形态保存较完整,细胞核与细胞浆饱满,杂质较少;应用95%乙醇常规液固定的细胞可不同程度损坏细胞结构,尤其损坏细胞浆的结构,杂质相对较多。经新型高性能、绿色环保组织细胞保存材料固定保存的胸腹腔积液组织细胞CK、CEA和P53的蛋白表达水平分别是91%、86%和88%,由95%乙醇常规固定液保存的组织细胞CK、CEA和P53的蛋白表达水平分别是46%、38%和31%,两种保存方法相比具有显著性差异(P<0.05)。结论新型高性能、绿色环保组织细胞保存材料高效、环保、性能优良,能较好保存胸腹水组织细胞的形态学特征,对胸腹腔积液组织细胞蛋白质的固定效果较好,可广泛推广应用于组织细胞的固定和保存。

Objectives To evaluate the performance of a new highly efficient and environment-friendly tissue cell fixatives for preserving the morphologies and properties of pleural and peritoneal effusions. Methods Fifty-six specimens of tissue cells from pleural and peritoneal effusions were preserved using the new preservative or 95% ethanol. HE staining and Western blotting were employed to detect the morphologies and protein expression levels of CK, CEA and P53 of the cells after fixation. Results The new preservative well preserved the morphologies of the cells from the pleural and peritoneal effusions, and the nuclei and cytoplasm were intact with little debris. The conventional preservative （95% ethanol） caused noticeable structural damage of the tissue cells, especially the cytoplasm where obvious debris were seen after fixation. CK, CEA and P53 protein expression levels in the cells were 91%, 86% and 88% after fixation with the new preservative, significantly higher than those （46%, 38% and 31%, respectively） in cells fixed with 95% ethanol （P〈0.05）. Conclusion The new preservative is efficient and environment-friendly for preserving the morphologies as well as the proteins of tissue cells from pleural and peritoneal effusions well, demonstrating its potential in tissue cell fixation and preservation.
