Effect of famotidine on radiation induced apoptosis in human peripheral blood leukocytes

 ABSTRACTBackground: Radioprotective effects of famotidine, an antagonist of H2 receptor clinically used for peptic ulcer treatment, was previously shown on radiation-induced micronuclei and chromosomal aberration in human peripheral blood lymphocytes and mouse bone marrow cells. This study was conducted to investigate radioprotective property of famotidine against radiation induced apoptosis i...

Three dimensional conformal radiation therapy in prostate adenocarcinoma: survival and rectal toxicity.

Technological advances in radiation beam planning and linear accelerator based radiation delivery have led to the development of three dimensional conformal radiation therapy (3D-CRT). The 3D-CRT clinical treatment in our hospital was started in September 1998 and till December 2002, 51 patients with M(0) stage prostate carcinoma were treated. Treatment method consisted of pelvis and leg immobi...

The Cytoprotective Effect of Amifostine Against Radiation Induced Toxicity

Radiation treatment is an important therapeutic option for a number of malignancies (American Cancer Society), but its use is frequently limited by adverse effects on normal tissues (Stone et al., 2003). Thus, the goal of most oncology treatments is to maximize the antineoplastic effect while minimizing deleterious outcomes for the patient. WR-2721 was developed by the U.S. Army Anti-Radiation ...

Radiation Induced Bystander Effect

Introduction: Radiation effects observed in cells that are not irradiated are known as non-targeted effects.  Radiation induced bystander effect (RIBE) as a kind of non-targeted effect has been introduced in recent  years.  RIBE  occurs  in  unexposed  cells  which  are  related  to  adjacent  or  distant  irradiated  cells.  RIBE  contradict with "target theory" which necessitates radiation tr...
