background: the aim of the present study was to evaluate the radioprotective effect of grewia asiatica fruit pulp extract (gae) on swiss albino mice exposed to gamma radiation. in the present study radioprotective efficacy of grewia asiatica (rich in anthocyanin, carotenes, vitamin c, etc.) was studied against radiation induced biochemical alterations in mice cerebrum. materials and methods: fo...

background: to evaluate the radioprotective potential of punica granatum fruit rind extract (pgre) in mouse testes. materials and methods: adult male mice were divided into four groups. group i was kept without any treatment. group ii was irradiated with 8gy co60 gamma irradiation and group iii was given pgre one hour before irradiation. group iv was fed with pgre at the rate of 10 mg/kg body w...

background: the specific antibody response against newcastle disease virus (ndv) in the blood serum of chickens hatched from eggs exposed to low dose gamma-radiation was studied. materials and methods: two groups of eggs of commercial meat chicken lines were irradiated with the dose of 0.30 gy 60co gamma-rays before incubation and on the 19th day of incubation, respectively. the same number of ...

in order to improve the performance of a newly developed radiochromic film, gic-79, somedosimetric characteristics of this film have been studied based on relevant standard practice. the presentstudy describes some parameters that may affect the dosimeter response before, during, and after irradiation. the effect of absorbed dose rate on dosimeter response was determined by irradiating dosimete...

large quantities of radiopharmaceuticals prescribed for treatment and diagnosis are excreted through kidney. therefore, radiation unwanted dose is created in kidney. as a result, exact calculation of prescribed radiopharmaceuticals amount is important. monte carlo method is used for simulation of radiation transport in body due to random nature of radiation. in this research, for the first time...

The purpose of the research was determine the effects of gamma ray on seed germination, seedling height and root length of Rice (Oryza sativa L. spp. Indica cv. MR219) to identify the Lethal Dosage of the radiation. Paddy seeds of MR219 were exposed to different doses of gamma radiations viz 50,100,150,200,250,300,350,400,450,500,600,700,800,900 and 1000 Gy using 60Co as the radiation source. T...

background: in some areas of ramsar, a city in northern iran, residents receive a much higher annual radiation exposure than is permitted for radiation workers. induction of adaptive response in residents of ramsar has been reported previously. in this study induction of such a response in short term exposure to high background levels of gamma radiation is investigated. materials and methods: f...

background: ramsar (mazandran province) is known for its extremely high levels of natural background radiation. although no excess cancer rate is reported in these areas by epidemiological studies, the study of tumor markers in the inhabitants of these areas may shed some light on the impact of high levels of background radiation on cancer induction. materials and methods: the level of backgrou...
