Cathode Rays on Proteins of Serum
Exper iments conducted by Dr. Carrel in this labora tory revealed t ha t chicken fibroblasts underwent a ve ry characterist ic change when cul t ivated in serum which had been submit ted to irradiat ion b y cathode rays. The cells resembled in appearance those of colonies cul t ivated in proteoses or peptones. Their cytoplasm was completely filled with granulations but , unlike degenerating cel...
متن کاملrelative biological effectiveness (rbe) of 131i radiation relative to 60co gamma rays
objective: to assess relative biological effectiveness (rbe) of 131i radiation relative to 60co gamma rays in glioblastoma spheroid cells. materials and methods: in this experimental study, glioblastoma spheroid cells were exposed to 131i radiation and 60co gamma rays. radiation induced dna damage was evaluated by alkaline comet assay. samples of spheroid cells were treated by radiation from 13...
متن کاملThe Effects of Cathode Rays on the Proteins of Serum
The effects of cathode rays on the proteins of serum appear to be (1) denaturation of a large proportion of the albumin and globulin with the formation of products that are soluble at the pH of the serum; (2) the production of a tough and exceedingly insoluble substance on the window of the cell where most of the absorption of electrons occurs; (3) a slight hydrolytic cleavage of the protein mo...
متن کاملGenetic Effects of X-Rays and Cathode Rays on Oocytes of Habrobracon.
IFFERENCES in sensitivity of oocytes to X-irradiation depending upon stage in meiosis when treatment occurred, have been shown for a number of organisms including Habrobracon (WHITING l938,1941,1945a, 1945b; ATWOOD, VON BORSTEL and WHITING 1956). Studies have also shown that death of Habrobracon embryos following irradiation of oocytes in late metaphase and in late prophase (diplotene) was attr...
متن کاملThe Effect of Cathode Rays upon Certain Bacteria
1. For the two motile bacilli, B. coli and B. aertryke, the absorption of a single 155 K.V. electron is sufficient to cause death. Furthermore, all, or nearly all, the electrons absorbed are lethal. The same is undoubtedly true of Staphylococcus aureus. In addition to providing a quantitative picture of the interaction of bacteria and cathode rays, these results suggest that radiation of the en...
