弱激光治疗月经过多症

Low Energy Laser Treatment of Menorrhagia

用弱激光(He-Ne激光)探索性治疗109例月经过多症,近期平均有效率为87.16％,经血量平均可减少47.1％,初步认为此法是一种无创伤和无副反应可治疗月经过多的新方法。为了探讨疗效的机理,治疗前后测定子官内膜和月经血中的前列腺素(PC)四项指标,部分结果提示,疗效的获得可能与调节子宫局部PG间的平衡有一定关系。

Menorrhagia is a common symptom of a variety of gynecological diseases. From 1989～ 1991, we have treated 109 cases of menorrhagia by low energy He-Ne laser (output power 30mW, power density 9,55mW/cm^2, energy density 5.73J/cm^2, direct irradiation on the surface of uterine cervix by its stimulative action) with a rather satisfactory result. The average effective rate was 87.16%(functional uterine bleeding 89.3%, myoma of uterus 85%, bleeding after IUD 78.0%, bleeding after childbirth or induced abortion 80%) . The average amount of bleeding was reduced by 47.1%, It has been proved that low energy laser is an effective, non-traumatic and painless method in treatment of patients with menorrhagia. To study the mechanisms of treatment, the quantitative determination of PGE_2, PGF_(2a). 6-Keto PCF_a, TXB_2 in endometrium and blood flow before and after treatment were carried out. The results sugges(?)ed that the effectiveness may be related to the regulation of the local PG level in the uterus tissue.
