Abstract:
0.05).The maximum relaxant forces of vitrification and fresh arteries groups were greater than the freezing group(P 0.05).The arteries of three groups began obvious relaxant responses when sodium nitroprusside was 10-7 mol/L, and nearly reached their maximal relaxant responses when sodium nitroprusside was 10-4 mol/L.CONCLUSION:The vitrification could preserve more active smooth muscle cells of arteries than the freezing method.The norepinephrine has better effect on contraction ability of artery, which preserved in the vitrification group than the freezing group;however, there is no difference in relaxation of sodium nitroferricyanide.
