title: Karyokinetic reactions in rat kidney proximal convoluted segment epithelium on long-term lead supply with drinking water.
abstract: In the rat kidney proximal convoluted segment epithelium the development of intranuclear inclusion bodies was observed after long-term lead administration with the drinking water. The inclusion bodies were PAS-positive. By electron microscopy they were identified as composed of filaments and granules lacking any kind of surrounding membrane. During the experiment, the nuclear volumes increased commensurately with the duration of lead exposure. The nuclear volume increase was considered a physiological reaction since it began long before the first appearance of intranuclear inclusion bodies.
