چکیده
石井直 明,鈴 木堅之:東 海大学医学部分子生物学教室 伊勢原市望星台 〒259-11 Nematode/Radiation/Aging The life-shortening effects of ultraviolet light (UV) and X-rays were investigated with a strain of free-living nematode, Rhabditidae tokai . UV exhibited a significant life-shortening effect on adult worms, and it also inhibited growth of larvae , hatching of eggs and reproduc tion. Sensitivity to UV was decreased with increasing ages. In contrast, nematodes showed a marked resistance to X-rays. Data were obtained suggesting that X-ray-induced single strand breaks in DNA can be rapidly and efficiently rejoined by a repair mechanism . Mal formations were observed when immature larvae were irradiated with X-rays .

Investigation of Low-Pressure Ultraviolet Radiation on Inactivation of Rhabitidae Nematode from Water
BACKGROUND Rhabditidae is a family of free-living nematodes. Free living nematodes due to their active movement and resistance to chlorination, do not remove in conventional water treatment processes thus can be entered to distribution systems and cause adverse health effects. Ultraviolet radiation (UV) can be used as a method of inactivating for these organisms. This cross sectional study was ...

متن کاملInvestigation of the production of free radicals in ultraviolet irradiation using SnO2:Eu nanoparticles
In studying the ultraviolet (UV) radiation, one of the important factors is the possibility of generating a variety of free radicals inside the body by these radiations. In this paper, a method of estimating the amount of hydroxyl radicals produced by ultraviolet rays was investigated using nanoparticles of tin oxide doped with uropium. In this method, the change in absorption intensity of meth...
متن کاملEffects of Crop Residue on the Persistence of Steinernema carpocapsae.
We determined the effects of crop residue on the persistence of an entomopathogenic nematode, Steinernema carpocapsae. During 2 consecutive years, nematodes were applied at rates of 2.5 x 10 and 1.0 x 10 infective juveniles/m(2) to small field plots planted with corn. Nematode persistence was monitored by exposing Galleria mellonella larvae to soil samples from plots with and without crop resid...
