A Clinical Study of Photodynamic Therapy for Superficial Esophageal Carcinoma by YAG‐OPO Laser
Diagnostic and Therapeutic Endoscopy, Volume 4, Issue 4, Page 173-176, 1998., 1997 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

Diagnostic and Therapeutic Endoscopy, Volume 1, Issue 1, Page 9-18, 1994., 1993 Lung cancer is a leading cancer site in men and women with a high incidence and mortality rate. Most patients are diagnosed when the disease has already spread. An early, detection and immediate and accurate histological or cytological diagnosis are essential for a hopeful outcome.

Photodynamic Therapy for Superficial Esophageal Cancer Using an Excimer Dye Laser
Diagnostic and Therapeutic Endoscopy, Volume 1, Issue 2, Page 99-105, 1994., 1994 In order to improve the therapeutic effectiveness of photodynamic therapy with Photofrin II and laser light for superficial esophageal cancer, we employed an excimer dye laser instead of an argon dye laser. Eight superficial esophageal cancer lesions (7 cases) were treated.

Ether-derived alkanes from sedimentary organic matter
, 1990 Glycerol ether lipids have been detected in the bitumen of DSDP sediments from Sites 467, 440B and 380 and from the Green River Shale. The alkyl side groups of these ethers were determined by conversion into deuteroalkanes.
