长脉宽800nm激光脱毛治疗对腋下汗腺分泌的影响

The Effect of Long Pulsewidth 800 Diode Laser in Hair Remoal Technique on the Function of the Axillary Sweat Gland Excretion

目的观察长脉宽800nm半导体激光脱毛时对皮肤汗腺的影响。方法采用自身对照方法对14例志愿者进行了5次腋下激光脱毛治疗,在最后1次治疗结束后,采用称重法测定双侧腋下汗腺分泌速度,其中6例志愿者进行了组织学研究,1例志愿者进行了电镜观察。结果经过5次治疗后,所有患者治疗侧腋毛基本完全脱除,疗效满意。研究结束时测治疗侧汗腺分泌速度为:7.124±8.190mg/(cm2·h),而对照侧为7.880±10.075mg/(cm2·h),差异无显著性(P>0.05)。电镜下未发现明显超微结构变化。结论长波长800nm半导体激光具有良好的脱毛效果,对汗腺功能无影响。

Objective To study the effect of long pulsewidth800Diode Laser in hair removal technique on the function of the axillary sweat gland.Methods Fourteen volunteers undergoing5hair removal treatments using long pulsewidth Diode Laser were studied under auto-control study.After the last treatment,the overall excretion of the axillary sweat glands of all volunteers were measured using gravimetric technique,skin biospies from6volunteers were studied histologically,and one under electronmicroscopy.Results After5hair removal treatments,the axillary hairs were removed almost completely,with excellent therapeutic effect.At the end of the study,the excretion rate of sweat on the treatment side was:7.1247.124±8.190mg/cm 2 ·h,while the control side7.880±10.075mg/cm 2 ·h,there was no statistical difference(P>0.05).No significant histological and ultrastructural changes were observed in the skin biopsies.Conclusion The long pulsewidth Diode Laser is a safe hair removal technique with good result and without adverse effect on the function of axillary sweat gland excretion.
