quantitative and qualitative analyses of the refringence phenomen in immunocompetent cells of various organs of rabbits and cba line mice under conditions of immunological activity , as well as in those of children with ataxia-teleangiectasia , showed that immunoblasts contained predominantly non-refringent nuclei , mature plasmatic cells -- mainly highly refringent nuclei , and young plasmatic cells occupied a position in the middle of the two .
