The linkage of two mutations leading to increased sensitivity to ultraviolet light and 60Co gamma rays was determined in the slime mould Dictyostelium discoideum using a genetic analysis based on the parasexual cycle. Diploids were selected from a mixture of radiation-sensitive, temperature-resistant and radiation-resistant, temperature-sensitive haploids on the basis of simultaneous radiation ...
Erythrocyte/Potassium exchange/Radiation Erythrocytes irradiated with 60Co ƒÁ-rays took up more extracellular 42K+ and released more intracellular 42K+ during and immediately after irradiation at 37•Ž than did unirradiated control. The result of K+ transport was contrasted with the well-known K+ loss on prolonged incubation. However, total K+ and ATP levels in irradiated cells did not change si...
Ethanolic extract of propolis (EEP) was tested as a protective agent against gamma irradiation in mice. The mice were exposed to 6 Gy gamma irradiation from a 60Co source, and were treated intraperitoneally with EEP, administered before and after their irradiation. While the non-treated mice expired within 12 weeks, the mice that received a series of EEP treatments survived the irradiation, and...
