Roentgen Ray Intoxication
These experiments show that the common laboratory animals are about equally sensitive to the x-ray given over the abdomen. The clinical reaction following a M.L.D. is very similar and the intestinal pathology almost identical. The rat and guinea pig are slightly more sensitive to the x-ray than are the dog, cat, and rabbit. By contrast birds, frogs, and reptiles are very resistant to the x-ray ...
متن کاملBreeding erect plant type sweetpotato lines using cross breeding and gamma-ray irradiation
Few sweetpotato (Ipomoea batatas Lam.) cultivars with erect plant type are available despite their advantages over spreading type, such as simplicity of cultivation and ability to adapt to limited space. One of the reasons is insufficiency of their agronomic characteristics for table use. So, it is important to overcome these drawbacks of ER-type lines. We attempted to breed new erect plant typ...
متن کاملA Study of Renal Function in Roentgen Ray Intoxication
Our experiments give no support to the current belief that an x-ray nephritis may be produced by direct or indirect action of the hard Roentgen rays. Moderate doses of x-rays given repeatedly over considerable periods of time have no demonstrable influence on renal function or renal structure. With x-ray exposures of the abdomen and shielding of the kidneys fatal intoxication may be produced wi...

متن کاملDiversifying Selection in Plant Breeding
Open access, freely available online " Some qualities nature carefully fi xes and transmits, but some, and those the fi ner, she exhales with the breath of the individual as too costly to perpetuate. But I notice also that they may become fi xed and permanent in any stock, by painting and repainting them on every individual, until at last nature adopts them and bakes them into her porcelain " —...
