Effects of 35 Hz, 2 mT Magnetic Field on Peripheral Blood Lymphocytes of Human In Vitro and Rat In Vivo
In this research we have studied the effects of extremely low frequency magnetic field on the peripheral blood lymphocytes chromosomes of human in vitro and rat in vivo. By this means, we used 60 blood samples of 10 men as well as 40 rats. Of 60 human blood samples ,40 samples (in two group of 20) were selected as test groups and placed into the 2 mT and 35 Hz magnetic field. The blood samples,...
متن کاملCytogenetic Effects of Tritiated Water (HTO) in Human Peripheral Blood Lymphocytes in vitro
The yield and distribution of unstable chromosome aberrations induced in human lymphocytes by tritiated water (HTO) has been measured. Tritiated water was mixed with heparinised blood in calculated amounts so as to give 0.1 Gy to 1.5 Gy, 30min and 2 hours. After culturing for 48 hrs, the dicentric yield was measured as a function of dose to the blood. Using a linear quadratic dose-effect relati...
متن کاملCytogenetic Effects in Rabbit Peripheral Blood Lymphocytes after in Vitro Low-dose Gamma Irradiation
The cytogenetic effect of low-dose gamma irradiation on the heredity structures of rabbits was studied. Rabbit peripheral blood lymphocytes were irradiated in vitro within the dose range 0.25-1.0 Gy on Rokus equipment with Со radiation source at a dose rate of 2.22 cGy/s. The analysis of cytogenetic data showed that the frequency of induced chromosomal aberrations in rabbit peripheral blood lym...
متن کاملGenotoxic Effects of Hypericum heterophyllum Vent
Hypericum species, growing wild in Anatolia, widely used in traditional medicine in Turkey. In order to determine the genotoxic effect of Hypericum heterophyllum, human lymphocytes were incubated with the aqueous extracts. The increasing extract concentrations of Hypericum heterophyllum induced micronucleus. The rise of micronucleus shows that Hypericum heterophyllum at high concentrations may ...
متن کاملIn vivo Exposure Effects of 99mTc-methoxyisobutylisonitrile on the FDXR and XPA Genes Expression in Human Peripheral Blood Lymphocytes
Objective(s): In recent years, the application of radiopharmaceuticals in nuclear medicine has increased substantially. Following the diagnostic procedures performed in nuclear medicine departments, such as myocardial perfusion imaging, patients generally receive considerable doses of radiation. Normally, radiation-induced DNA damages are expected following exposure to a low-dose ionizing radia...
