[ . the Effect of Monochromatic Ultra - Violet Light upon Vaccine Virus
I t has been known for many years tha t ul tra-violet light is bactericidal. Finsen and Dreyer (1), in 1903, were probably the first to Show tha t light with short wave-lengths is virucidal also. More recent ly (2-7) other reports have appeared dealing with the effects of ul tra-violet irradiation upon bacteria, viruses, and enzymes. For the most par t , however, single wave-lengths have not be...
متن کاملResults of Irradiating Saccharomyces with Monochromatic Ultra-violet Light
Data obtained on yeast irradiated with monochromatic ultra-violet radiation has been analyzed for the number of quantum hits involved in the production of different degrees of inhibition of cell division, according to the method proposed by Mme. Curie (1929). Sufficient data are not available for a rigorous determination, but the calculated results tend to indicate that a multiple hit to kill r...
متن کاملProduction of Saltants of Chaetomium globosum by Monochromatic Ultra-Violet Irradiation
Experiments have been made on the production of mutations by irradiation with monochromatic ultra violet light. The basic object of the experiments was to see whether thresholds exist in this phenomenon of the type familiar in photo-chemical reactions. If such thresholds can be demonstrated, a technique of analysis of biological material might be opened up similar to that used by the physicist ...
متن کاملUltraviolet Radiation Effects on Ehrlich Ascites Tumor Cells Observations Using a Flying Spot Ultraviolet Microscope*
A flying spot ultraviolet microscope, employing a fast scan and pulsed operation of the raster, has been used to induce radiation damage in ascites tumor slide cultures, and to study by time-lapse cinematography the progressive stages of cell damage. The cells observed came from a strain (EFT) of the Ehrlich ascites carcinoma. Irradiated cells were found to show a characteristic syndrome of dam...
