Background: Radioprotective capability of histamine H2 receptor antagonists have been shown in several in vivo studies mainly using animal models. However, to verify the effectiveness of these agents in clinical applications, studies should be performed on human cells. In the present study radioprotective properties of these agents was examined in vitro on human lymphocytes using metaphase anal...

this study aimed at examining the effects of iranian efl learners’ anxiety, ambiguity tolerance, and gender on their preferences for corrective feedback (cf, henceforth). the effects were sought with regard to the necessity, frequency, and timing of cf, types of errors that need to be treated, types of cf, and choice of correctors. seventy-five iranian efl students, twenty-eight males and forty...
objective: free radicals generated by ionizing radiation attack various cellular components such as lipids. the lung is a very radiosensitive organ and its damage is a doselimiting factor in radiotherapy treatments. melatonin (mlt), the major product of the pineal gland acts as a radioprotective agent. this study aims to investigate the radioprotective effects of mlt on malondialdehyde (mda) le...
background : we intend to study the inhibitory effect of sulfur compound in ramsar hot spring mineral on tumor-genesis ability of high natural background radiation. objective : the radioprotective effect of sulfur compounds was previously shown on radiation-induced chromosomal aberration, micronuclei in mouse bone marrow cells and human peripheral lymphocyte. ramsar is known for having the high...
In this brief communication, we describe the existence o f a pulmonary polyamine uptake system. We discuss the presence o f similar uptake systems in a numbcr o f other cell typcs. in particular certain tumour cells. Finally, we discuss the possible therapeutic exploitation of this pulmonary polyaminc uptake system. in particular, in relation to the design of novel anticancer agents and better ...
PURPOSE Discovery of agents that protect or mitigate normal tissue from radiation injury during radiotherapy, accidents, or terrorist attacks is of importance. Specifically, bone marrow insufficiency, with possible infection due to immunosuppression, can occur after total body irradiation (TBI) or regional irradiation and is a major component of the acute radiation syndrome. The purpose of this...
