objective(s)the aim of this study was to investigate the radioprotective effect of green tea against genotoxicity induced by gamma irradiation in cultured blood lymphocytes from 5 human volunteers.materials and methodsperipheral blood samples were collected from volunteers before and 1, 3 and 5 hr after drinking a decoction 4 g green tea in 280 ml boiling water for 5 constitutive days with the ...

A majority of potential radioprotective synthetic compounds have demonstrated limited clinical application owing to their inherent toxicity, and thus, the seeking of naturally occurring herbal products, such as ginseng, for their radioprotective capability has become an attractive alternative. In general, ginseng refers to the roots of the species of the genus Panax. As a medicinal herb, ginsen...

Aromatic plants are often used as natural medicines because of their remedial and inherent pharmacological properties. Looking into natural resources, particularly products of plant origin, has become an exciting area of research in drug discovery and development. Aromatic plants are mainly exploited for essential oil extraction for applications in industries, for example, in cosmetics, flavori...

Herbal plants and products represent important source of natural antioxidant offer an alternative to synthetic protectors. Moringa oliefera, a herbal medicinal plant has been screen for their radioprotective activity. For the purpose study male Swiss albino mice were divided into seven groups. The exposed gamma radiation (2.5 Gy 5.0 Gy) also provided mercuric chloride (0.5 ppm) both separately ...

Objective(s): Curcumin, a natural plant product, is commonly known as wonder drug of life, but the poor bioavailability of its free form has hindered its clinical development. The aim of the present study was to investigate the radioprotective effect of nanocurcumin on survival of mice under whole body X-ray irradiation. Materials and Methods: The Naval Medical Research Institute (NMRI) mice ra...

Ionizing radiations are one of the predominant exogenous factors that have deleterious consequences to human life The biological effects of the radiation cause damages to DNAs, lipids and proteins. Exposure to high amounts of ionizing radiation causes damages to the hematopoietic, gastrointestinal or central nervous systems, depending on radiation dose. Hence, there is an urgent need to prevent...

Background We intend to study the inhibitory effect of sulfur compound in Ramsar hot spring mineral on tumor-genesis ability of high natural background radiation. Objective The radioprotective effect of sulfur compounds was previously shown on radiation-induced chromosomal aberration, micronuclei in mouse bone marrow cells and human peripheral lymphocyte. Ramsar is known for having the highes...

Radiation is an important source of free radicals in living systems. Ionizing radiations such as γ-rays exert their biological effects through generation of reactive oxygen species and the resultant damage to DNA and cellular membranes. Several natural compounds, especially with antioxidant abilities are known to be radioprotective. Baicalein (5,6,7-trihydroxy-2-phenyl-4H-1-benzopyran-4-one), a...
