A New Method for Marking Small Laboratory Animals.
نویسنده
چکیده
If, therefore, amber has a resistivity of 10-'8Q/cm, XMS has about 3 x 10-'7Q/cm. The new material ranks very close to amber in its insulating qualities and will in many cases be a very good substitute for it. Its resistivity is equal to or perhaps a little higher than quartz, but the ease of molding it will make it superior to quartz. Whereas amber insulators are usually flamed to remove surface charges, XMS-10023 will charge itself when brought into the flame. Cleaning with alcohol will suffice to make it ready for use. For atmospheric electric and Radon measurements the qualities of this plastic seem to be quite satisfactory. H. LANDSBERG A. I. INGHAM THE PENNSYLVANIA STATE COLLEGE

Studying a specific tumor marker by a new method and analyzing its efficiency in labeling animals
Purpose: To recognize affective factors in delivering X-ray contrast agents (which have high atomic number) via gallium carrier to liver or lymphatic neoplasm cells. Materials and Methods: Since uptake of gallium by liver has been reported in numerous researches, it was bonded with a contrast media (metrizoate). X-ray imaging was done to determine geometric features of liver. Results: Rad...

متن کاملEffect of Gamma Irradiation on Microbial Decontamination, Crude Nutrient Content, and Mineral Nutrient Composition of Laboratory Animal Diets
Laboratory animal models are an important part of test design. Certain conditions such as microbial contamination in diets of these models could affect the results of experiments. One of the most important routes that predispose to contamination is generated through feeding of laboratory animals. This study aimed to show the effect of gamma irradiation in reducing bacteria concentrations,...
