background: cytotoxic therapy can lead to prolonged azoospermia or even sterility. in the present study, we investigated the morphological changes of mouse testes after gamma-radiation. methods: after anaesthetizing of nmri mice, testes and their surrounding tissues were irradiated using a cobalt therapy machine. four experimental groups were irradiated with fractionated doses of: 1.5+8, 1.5+12...

investigation have been carried out on the variation of γ-radiation dose (produced by radium daughters), due to changes of temperature, in order to evaluate its effects on living substances specially on man and to study to evaluate its effects on living substances specially on man and to study the variation of observed dose and its effects, following measurements have been done in five differen...

background:  the development of nanotechnology has been a boon to mankind as its significance paved the way for several applications in therapeutics. this study was to evaluate the anti-arthritic capability of nano selenium-lovastatin mixture (lov-se) against inflammatory cascade in arthritic irradiated rats. materials and methods: animal model of arthritis was organized by subcutaneous injecti...

abstract  introduction: recently uses of medium and high energy x-rays has been increased in iran and radiotherapy centers along with a variety of accelerators have been installed in some provinces. in the other hand there is no sufficient skill in designing and making radiotherapy treatment rooms. this study was conducted to evaluate the efficacy of different mixtures of barite concrete for sh...

elevated amounts of free radicals due to ionizing radiation have damaging effects on the body. h2-receptor antagonists have potential oxygen radical scavenging properties. we tried to determine the effects of two h2-receptor antagonists (cimetidine and ranitidine) on lipid peroxidation (lpo) and lipid profile (lp) in plasma and liver of γ-irradiated (1gy/day for 3 days) balb/c mice. the control...

Introduction: The effects of the low dose of ionizing radiation are not thoroughly evident due to an unavoidable increase of occupational exposure and the widespread application of ionizing radiation in medical and industrial fields. The aim of this study was to investigate immune system responses following the low doses of ionizing radiation. Materia...

background: the effect of low dose radiation on immune system is shown. ionizing radiation can affect cytokine production and polarization of t helper cells. objective: the current study focused on ionizing radiation in ukrainian children residing in a contaminated area with clinical irritable bowel syndrome. method: our study included 75 rural children population aged 4-18 yrs, who lived in a ...

Introduction: Coronary angiography is a Diagnostic-Therapeutic method involving ionizing radiation. This method causes to DNA damage with form double stranded breaks which is followed by the phosphorylation of the histone, H2AX. H2AX is a key factor in the repair process of damaged DNA which will accumulate to damage sites. In human cells, H2AX constitutes about 10% of the H2A ...
