The reaction of the insect excretory tissue to a heavy metal: uranyl nitrate


, : The reaction of the insect excretory tissue to a heavy metal: uranyl nitrate. Archives D'anatomie, D'histologie et D'embryologie Normales et Experimentales 62: 87-94

The present paper describes the modifications induced in Malpighian tubules of Locusta migratoria by uranyl nitrate. These modifications are observed only if doses injected are approximately a hundred times higher than those which affect the renal epithelium of Vertebrates. The elimination of the uranyl salts seem to occur by apical excretion of dense metallo-proteic granules. When strong doses are used, metallic particles are seen on the basal membrane and in the extracellular spaces. Such intracytoplasmic particles are rarely observed.
