Photodynamic Therapy With YAG-OPO Laser for Early Stage Lung Cancer
Photodynamic therapy (PDT) utilizing Photofrin is proving to be effective for the treatment of early stage lung cancers. The effect of PDT utilizing YAG-OPO laser as new light source was evaluated in 26 patients (29 lesions) with early stage lung cancers. YAG-OPO laser is solid state tunable laser which is easy to change wavelength between 620 and 670 nm exciting various kinds of photosensitize...
متن کاملA Clinical Study of Photodynamic Therapy for Superficial Esophageal Carcinoma by YAG-OPO Laser
A cooperative clinical study of photodynamic therapy (PDT) for superficial esophageal carcinoma was conducted at 6 medical institution. PHE (2mg/kg) with high tumor affinity was used as the oncotropic compound. The light source was a pulse wave YAG-OPO laser with high penetration into the tissue. Irradiation was performed at an energy density of 60-180 J/cm(2) 48-72 h after PHE administration. ...
متن کاملClinical Outcome of Er: YAG Laser Application for Periodontal Surgery
Clinical application of lasers in periodontal surgery has continued to expand in the last decade; however, controversies remain regarding their use. This article will describe the clinical application of erbium: YAG lasers for periodontal surgery: flap operations, osseous surgery, and semi-lunar coronally repositioned flap procedures, and peri-implantitis treatment by laser will be discussed.
متن کاملCooperative Clinical Trial of Photodynamic Therapy for Early Gastric Cancer With Photofrin Injection® and YAG-OPO Laser
BACKGROUND AND OBJECTIVE Photodynamic therapy (PDT) treats malignant tumors using photosensitizers and light. We employed a new pulse laser as the excitation light source for PDT, i.e. an optical parametric oscillator (OPO) system pumped by a Q-switched Nd:YAG laser, because it provides extremely high peak power. STUDY DESIGN/MATERIALS AND METHODS The effects of PDT using the photosensitizer ...
متن کاملDental Er: YAG laser and its clinical application
An Er: YAG laser is a near infrared laser with a wavelength of 2.94m. This wavelength is identical to the peak wavelength of the light most readily absorbed by water. When used on living tissue with a sufficient water content, this laser causes a rapid evaporation of the water in just the most superficial layer of tissue, without greatly affecting the tissue in the neighboring area. The present...
