摘要：

背景：实验发现链球菌溶血素O引起的细胞通透在一定程度上是可逆的，链球菌溶血素O产生的孔道在Ca2+存在的情况下可以自然封闭。
目的：观察链球菌溶血素O是否可以使猪成纤维细胞的通透性发生改变，及不同质量浓度的链球菌溶血素O对细胞状态的影响。
方法：分别使用质量浓度为0，230，300，400 μg/L的链球菌溶血素O溶液处理猪成纤维细胞，孵育50 min后，加入PI染液，观察细胞的通透率。加入含Ca2+的培养液封闭细胞后，分别观察细胞的形态变化及增殖能力的变化。
结果与结论：随着链球菌溶血素O溶液质量浓度的增加，细胞的通透率只轻度提高。链球菌溶血素O处理细胞后，细胞的形态没有发生明显的改变。质量浓度为230 μg/L的链球菌溶血素O溶液对细胞的增殖能力无明显影响，而300 μg/L和400 μg/L的链球菌溶血素O溶液明显地降低了细胞的增殖能力。提示质量浓度为230 μg/L的链球菌溶血素O溶液可以提高细胞的通透性，并保持细胞正常的形态及增殖能力。

Abstract:

BACKGROUND: Streptolysin O (SLO)-induced cell permeability is reversible to a certain extent, and the pores can be closed in the medium containing Ca2+.
OBJECTIVE: To observe whether SLO could improve the permeability of pig fibroblasts and to observe the states of cells treated with SLO of different concentrations.
METHODS: Pig fibroblasts were permeated with SLO solution of different concentrations (0, 230, 300 and 400 μg/L respectively). After incubation of 50 minutes, the cells were stained with PI to observe cell permeability. When adding the medium containing Ca2+, the cells were plated. Morphology and multiplication capacity of these cells were detected.
RESULTS AND CONCLUSION: Along with increase of SLO solution concentration, the cell permeability improved slightly. When cells were treated with SLO, the cell morphology was not changed. 230 μg/L SLO had no influence on the capacity of cell proliferation, and however, 300 μg/L and 400 μg/L SLO reduced the proliferation capacity significantly appearing statistically difference when compared with 0 μg/L group. These findings indicate that 230 μg/L SLO could increase cell permeability with keeping the normal shape and proliferation ability of cells.
