半导体激光诱导细胞凋亡脱毛及除腋臭的研究

Experimental Study on Apoptosis Induced By Semiconductor Laser to hair remove and armpit odor treatment

目的 :通过动物实验观察能否诱导细胞凋亡导致脱毛 ,并探索激光诱导细胞凋亡的机制。同时 ,观察和探讨在脱腋毛的同时 ,大汗腺细胞有无因激光的光热作用或诱导的细胞凋亡受到破坏 ,为治疗腋臭寻找一新的无创伤的治疗方法。方法 :分别用半导体激光以不同剂量对黑毛狗进行脱毛。分别在治疗即刻、治疗后不同时期通过电镜、流式细胞术、TdT介导的RdUTP缺口末端标记法 (Tunel法 )对比治疗效果 ,观察组织变化及其可能存在的凋亡改变 ,并初步探讨诱导细胞凋亡的机制及临床治疗意义。结果 :半导体激光照射后毛囊上皮细胞及大汗腺腺体细胞中出现凋亡细胞 ;低剂量重复治疗凋亡现象增加。结论 :激光照射后 ,毛囊上皮细胞及大汗腺细胞中有细胞凋亡现象。

Objective: To observe and explore the effects and mechanism of apoptosis on canine induced by Laser. Try to find a new approach to treat of armpit odor with no traumatism. Method: WE used different power of semiconductor Laser to irradiate the black hair canine to observe and evaluate the tissue effects with electroscope, flow cytometry and Tunel technique at different period of time after irradiation. Result: The apoptosis has been observed within the hair follicle cells and apocrine gland cells after irradiation. After repeat irradiation in low power level, more apoptosis has been observed. Conclusion: Apoptosis exists in hair follicle cells and apocrine gland cells after Laser irradiation.
