吸、戒烟对人体甲襞微循环的影响

对３０例吸烟者、３０例有吸烟史现戒烟者以及３０例无吸烟史者行甲襞微循环观测。结果表明，吸烟组甲襞微循环有明显改变，总积分值高于戒烟组和无吸烟的对照组（Ｐ＜００１）。其主要改变为：管袢输入枝、输出枝管径增宽，管袢扭曲、分叉，血流速度减慢，红细胞聚集度增加。戒烟组各项指标均明显改善，但与吸烟组比较差异显著（Ｐ＜００１）。与对照组比较，其形态改变尚未完全恢复（Ｐ＜００１）。以上结果提示，吸烟可引起机体的慢性微循环障碍，戒烟可对其造成的损害有所改善

Effects of Smoking and Give Up Smoking on Nailfold Microcirculation

The nailfold microcirculation were observed in 30 smoking men, 30 giving up smoking men and 30 no-smoking men. The results showed that there were obvious disturbance of nailfold microcirculation in smoking group, comparison with giving up smoking group and no-smoking group(all P<0.01). The smoking group showed that the deformity of capillary loops was abnormality, blood flow velocity decreased and erythrocyte aggregation increased. All indexes were obviously improved in giving up smoking group(P<0.01), but comparison with no-smoking group, the deformity of capillary loops didn't completely return to normal(P<0.01). The results suggest that smoking could affects normal of microcirculation, but give up smoking could improve microcirculatory disturbance caused by smoking.
