objective: ocular morbidity is widely observed when radiotherapy includes the orbit. oxidative stress generated by irradiation is responsible for this complication. in different studies, it has been shown that melatonin has antioxidative properties and a radioprotective role. the aim of this study was to evaluate the antioxidant role of melatonin against radiation-induced oxidative injury in ra...

Sainfoin (Onobrychis viciifolia Scop. Syn. Onobrychis sativa L.) is a bloat-safe forage crop with high levels of tannins, which is renowned for its medicinal qualities in grazing animals. Mutagenesis technique was applied to investigate the influence of gamma irradiation at 30, 60, 90, and 120 Gy on mitotic behavior, in vitro growth factors, phytochemical and nutritional constituents of sainfoi...

Seed of onion (Allium cepa L.) cv. Ailsa Craig were exposed to various doses of gamma radiation, i.e. 10,20.40.80. and 100 krad. Irradiation doses have no significant effect on seed viability, except the highest dose (100 krad) which resulted in reduced viabi lity. However, electrical conductivities of the leachates of seeds exposed to gamma radiation were higher than that of un irradiated seed...

Gamma irradiation is used as a phytosanitary treatment for tropical fresh fruit from some producing countries. An experiment was carried out to study the effect of gamma irradiation and season of harvest on the quality 'Pattavia' pineapple fruit. Fruit harvested in the summer and the rainy cool (winter) seasons were exposed to gamma radiation at dose levels of 0 and 400-600 Gy from a 60 Cobalt ...

The radioprotective activity of extracts from the red seaweed Callophyllis (C.) japonica was investigated in mice that underwent whole-body exposure to gamma radiation. A methanol extract of C. japonica and its fractions [hexane, ethyl acetate (EtOAc), butanol and the remaining H2O] were used. Each fraction (100 mg/kg body weight) was administered intraperitoneally (i.p.) 2 times into the BALB/...

In order to find an environmentally benign substitute to hazardous inhibitory agents, the inhibitory effect of gamma-irradiated chitosans against a mixed culture of denitrifying bacteria was experimentally evaluated. Unlike other studies using pure aerobic cultures, the observed effect was not a complete inhibition but a transient inhibition reflected by prolonged lag phases and reduced growth ...

Background: The present study has been carried out to investigate the effects of preovulatory stage gamma-irradiation of female mice in the absence or presence of vitamin E on numerical chromosome abnormalities in 8-cell embryos after mating with non-irradiated males. Materials and Methods: The 8-11 weeks adult female NMRI mice were whole body irradiated at preovulatory stage (post PMSG inject...

the aim of this study was to determine feasibility of gamma irradiation in broiler chicks’ diet and scrutiny of productive performance of broiler due to gamma irradiated diets. there were 256 broiler chicks (male and female) from arian strain. experiment was statistically analyzed using balanced complete randomized design with four factors (including four irradiation doses: 0, 6.7, 7.7 and 8.7 ...

The effect of cadmium chloride concentrations (25.50, 75, and 100 mg/kg soil), seeds pre-irradiated by low doses of gamma rays (15, 30, 45, and 60 Gy), potassium chloride (60 mg/kg soil) and the combination of cadmium + gamma and cadmium + potassium on Brassica rapa germination, oxidative stress and antioxidant system were investigated under laboratory and greenhouse conditions. Germination per...
