Objective: To discuss the clinical application and indication of laser gasification decompression through percutaneous lumbar intervertebral discs puncture.
Conclusion Ultrapulsed carbon dioxide laser gasification therapy is a perfect method for traumatic tattoo, especially for superficial tattoo without visible scars and the tattoos which are hard to apply operation, such as nose, lips.
Serum levels, both before and after laser vaporization combination with photodynamic therapy (PDT), of soluble interleukin-2 receptor (SIL-2R) and interleukin-2 (IL-2) as well as activity of natural killers (NK) were determined among 24 patients with either persistent or recurrent nasopharyngeal carcinomas (NPC) using double antibody sandwich technique, 3H-TdR incorporation and 125 I-UdR release techniques respectively.
The CO_2 laser has been used to treat cervicitis disorders since 1973. Curerrates for Ⅰ°、Ⅱ°cervicitis treated by CO_2 laser have reached 99.2 ~100%,but vaporization of endocervicai canal or conization are especially important for the treatment of Ⅲ °cervicitis.
The PVP that adopted was non-contact PVP system designed by American Laserscope Company,and the vaporized power of nominal out was 80 W and the electric coagulation power was 30 W.
METHODS:Ninety-eight inpatients(who were older than 60 years) with benign prostatic hyperplasia(BPH) were selected from Xijing Hospital Affiliated to Fourth Military Medical University of Chinese PLA between June 2005 and April 2006.Patients underwent surgical treatments:OP(n =28),PVP(n =37) and PVP+TURP(n =33) respectively.
Objective To investigate the efficacy and safety of photoselective vaporization treatment on benign prostatic hyperplasia(BPH)in the elderly over 70 years old.
目的探讨选择性绿激光汽化术(photoselective vaporization of the prostate,PVP)治疗70岁以上老年人良性前列腺增生(BPH)的疗效与安全性。
Other laser techniques, such as interstitial laser coagulation and contact laser vaporization of the prostate, have lost popularity due to complications with increased catheterization time, irritative symptoms, and infection rates.
Although Ho:YAG laser enucleation of the prostate is more difficult to learn and a slower procedure than potassium titanyl phosphate laser vaporization, the Ho:YAG laser is currently the most proven laser technique for BPH treatment.
In 1976, we successfully installed a 300w Carbon Dioxide Vaporization Laser Unit. Animal experiments showed that squamous ceil carcinoma, adenocarcinoma and melanoma can be instantaneously vaporized or carbonized on application of a laser beam of 170w or above with a beam-diameter of 1 cm, passing through beam manipulator. After vaporization an analysis of the carbonized tissue showed remnants of some intact cancer cells, which were found to have lost their vitality to regrow under tissue culture. Basing on...

CO2 laser has been used to treat gynecologio diseases in the Cancer Hospital for over 10 years.Experimental studies on rabbit's skin showed that near the laser beam focus destructive dept hspoints 1-1. 5mm (3W for 10 and 20 sec) in nonhairy areas, and 2.5-8mm (8W for 10, 20 and 40 seo)in hairy areas respectively. Using the portable CO2 laser unit a variety of lesions located in different areas of the vulvae. Have been treated including papilloma with dysplasia, Paget's disease, hemangloma, vascular leiomyom...
