[Effect of Suture Lines on Lung Adenocarcinoma Cell in vitro.].
BACKGROUND
The interaction of cell and medical biomaterial is one of the significant factors to affect clinical application of medical biomaterial. This research is to investigate three of suture lines how to affect the proliferation and cell cycle of Lung Adenocarcinoma cell A549.


METHODS
Three of suture lines are respectively cultivated with Lung Adenocarcinoma cell A549, after of 72 hours, to detect absorptance of each groups by MTT method in order to reflect the proliferation of Lung Adenocarcinoma cell A549 and to detect percentage of G1 period cell and S period cell of each of groups by flow cytometry.


RESULTS
Different of suture lines have effect differently on the proliferation and cell cycle of Lung Adenocarcinoma cell A549 (P<0.05). The effect of absorbent suture line on the proliferation and cell cycle of Lung Adenocarcinoma cell A549 is strong, the effect of chorda serica chirurgicalis is medium, the effect of slide wire is poor. Different length of each suture line have effect differently on the proliferation and cell cycle of Lung Adenocarcinoma cell A549 (P<0.05).


CONCLUSIONS
Three of suture line materials have different effect on the proliferation and cell cycle of Lung Adenocarcinoma cell A549, to reflect dose-effect relation.
