ABO gene encodes antigens surface red cells there reported relations between this phenotype pregnancy outcomes women. In study, medical records 792 healthy pregnant women were investigated their age test results including group with fasting sugar, hemoglobin, hematocrit, urea, creatinine cell counts analyzed statistical package for social sciences. The RBC count AB type was significantly higher than O...

<p>Medical professionals involved at intraoperative fluoroscopy are exposed to low doses of the occupational radiation exposures. The biological effects chronic low-dose on human health complex and have not been well established. aim present study is follow up hematological parameter changes during 2 years in medical ionization operating rooms.<strong></strong></p><p>22 (medical specialists technicians), chronically ionizing mobile C-Arm X ray machine, were...

Introduction: Oxidative stress is a common factor in cataract. Considering the antioxidant properties of hesperidin as flavanone glycoside from flavonoid family with radioprotective effect, this study aimed to determine protective effect on reducing oxidative eye lens tissue mature rats caused by gamma irradiation. Materials and Methods: A total 48 adult were randomly divided into six groups, namely, control, Dimethyl sulfoxide (DMSO), hesperidin, radiation, radiation + DMSO hesperidin. 15...

Background and Objectives.Stimulating the immune system by exposure to various allergens produce specific IgE has a significant role in pathogenesis of atopic dermatitis.Identifying disease-causing allergens, prevention those immunotherapy will play an important treatment Atopic Disease.The purpose this study was determine common northwest Iran patients with dermatitis that are resistant treatment.Materials methods.In descriptive-analytical study, serum levels total frequency were measured...

The effective dose received by humans from natural sources is about 2.4 mSv y(-1), but this 10.2 y(-1) for inhabitants of Ramsar, a city in northern Iran. Carcinogenesis one the most studied effects radiation, especially high doses. Nonetheless carcinogenesis low doses uncertain. A recent epidemiological study background radiation areas Ramsar showed that cancer incidence era lower than neighbors. reason different behavior under yet. NK cells, helper, and Cytotoxic T cells are important...

The effective radiation dose of human from natural sources is about 2.4 mSv/y and the limit for workers 20 mSv/y. Ramsar, a city in Iran, has been subject concern last forty years high level measured some spots as 260 Carcinogenesis one most studied effects especially doses. Recent studies showed that received by inhabitants this area, paradoxically don't have significant health effect. Natural killer (NK) cells cytotoxic T are important tumor immune surveillance CD107a widely expressed...

AIM: Oxidative and nitrosative stress triggers an extensive damage to the tissues.Many herbal chemical medicines have claimed possess antioxidant properties.Arbutin exists in some plants such as Pyrus Biossierana Bushe.In this study, inhibitory effect of arbutin against tert-butyl hydroperoxide induced cytotoxicity was studied using SYTOX TM Green assay for cell viability.The effects on generation malondialdehyde, nitric oxide, activity oxidative enzyme (Superoxide dismutase catalyze) amount...

Despite the improvements in cancer screening and treatment, it still remains as one of leading causes mortality worldwide. Nausea vomiting side effects different treatment modalities, such radiotherapy, are multifactorial could affect continuation patient quality life. Therefore, aim this study was to assess possible linkage between ABO blood groups radiation-induced nausea (RINV), also its incidence affecting factors. One hundred twenty-eight patients referring Tohid hospital Sanandaj,...

Some evidence shows that a pre-exposure to RF can mitigate the effects of subsequent exposures high doses ionizing radiation.We aimed assess effect non-ionizing radiation on survival, weight changes, food consumption, and water intake lethally irradiated rats.In this case-control study, we used commercial mobile phone (GSM, 900/1800 MHz) as well 2.4 GHz Wi-Fi router sources radiation. Forty-eight rats were randomly divided into six groups control, "8 Gy X-rays", phone, "mobile phone+8 Gy",...

Although the average effective human dose from natural background radiation is about 2.4 mSv per year, students of Saeid Nafisi school in Ramsar received doses 250 while studying there for over 5 years. The goal this project was a retrospective study health status former and their offspring. list (high radiation) Taleghani Kashani schools (ordinary provided by Department Education. After matching sex, age socioeconomic level obtaining consent, part 1 specifically designed questionnaire...

Purpose: Biochemical and histopathological properties of renal tissues were reported to be affected by both radiofrequency electromagnetic fields (RF-EMF) ionizing radiation. The radiation-induced changes in the kidney, including serum levels blood urea nitrogen (BUN) creatinine (Cr), could lead adverse health outcomes such as chronic kidney disease. These complications signify importance research this field. Thus, study, effects non-ionizing radiations, well their combination, assessed...

The High Natural Background Radiation Area (HNBRA) of Ramsar has been the subject concern in last 40 years for a high level radiation measured some spots as 260 mSv per year. Studies health status inhabitants did not show significant increase frequency cancer. In this study, aspects immune surveillance HNBRA residents were investigated. Our results showed that CD4+ and CD8+ percentage was higher compared to Ordinary (ONBRA) inhabitants. However, difference between also cells count CD4/CD8...

Radiosensitivity is an inheriting trait that mainly depends on genetic factors. it well known in similar dose of ionizing radiation and identical biological characteristics 9-10 percent normal population have higher response. Some reports indicate distribution breast cancer, immune diseases including autoimmune as example lupus, Myasthenia Gravies even the rate allergy are more frequent left handed individuals compared to right individuals. The main goal present study determination...

Low dose radiation will induce adaptation and following exposure to an adaptive dose, the cells are more resistance challenging doses. This phenomenon is known as radio-adaptive response. The aim of this study was investigate percentage apoptotic in peripheral blood samples patients which undergo myocardial perfusion imaging (MPI) with technetium-99m (Tc-99m) before thallium scan assess induction response.In study, 97 from 74 patients, referred nuclear medicine center Mazandaran Heart...

Radiosensitivity is an inherent trait, associated with a raised reaction to ionizing radiation on the human body. In radiotherapy and protection fields, individualization of patient's treatment one main topics. With goal determining biomarkers capable anticipating normal tissue side reactions, we studied association between Rh factor radiosensitivity.This experimental study was carried out from January June 2014 among 50 responders A blood group (25Rh+ 25Rh-) ages 22 23 in Babol, Iran.
