Background: Ferula gummosa Boiss. is a medicinal and economical plant belonging to Apiaceae family. It is a native herb of Iran and is in serious danger of extinction. Objective: Gamma irradiation is an environmental stress and can consider as a new tool to change the content of secondary metabolites in medicinal plants. The effect of gamma irradiation on phenolic content and radical sc...

hyssopus of­ficinalis l. is one of the most important medicinal plants. medicinal herbs are contaminated by microorganisms. conventional methods for reducing of microbial loads such as ethylene oxide, propylene oxide and also use of steam are hazardous and instead, non-thermal process such as microwave and gamma radiation are being used widely in order to eliminate the microbial contaminations ...

in this study the effects of gamma irradiation and frozen storage on sensory, chemical and microbial quality of fish fillets was investigated. hypophtalmyctis molitrix were equally divided to 12 fillests, then these 12 fillets were equally arranged in 4 groups (1-4). one group considered as control with no treatment and the other 3 groups was treated by 0.75, 3 and 5 kgy of gamma irradiation, r...

objective: ionizing radiation produces free radicals which induce dna damage and cell death. origanum vulgare leaf extract (ovle) is a natural compound and its capability of scavenging free radicals and its antioxidant activity have been demonstrated by many researchers. in this study, using micronucleus assay, radioprotective effect of ovle against clastogenic and cytotoxic effect of gamma irr...

Objective(s):Cervical cancer is a malignancy that is the second most common cause of death from cancer in women throughout the world. Paederus beetle (Paederus fuscipes) extract (PBE), contains bioactive compounds such as pederine which has cytotoxic properties and blocks DNA and protein synthesis at very low concentrations. In this investigation we tried to determine the effects co-treatment w...

background: previous investigations have revealed, cimetidine, a histamine h2-receptor antagonist, show radioprotective effects against gamma- and neutron-induced micronuclei in bone marrow erythrocytes. in this study, the anticlastogenic effects of famotidine and ranitidine, which act similar to cimetidine as histamine h2-receptor antagonists, was investigated. materials and methods : balb/c m...
