Autoradiographic studies on <i>Fasciola hepatica</i> L.

Abstract

Iron-59 (as a ferric chloride solution or as a component of haemoglobin) was introduced into the lumen of the gut of Fasciola hepatica . It was detected by autoradiography in high concentrations in the intestinal epithelium, the cuticular epithelium, the myoblasts and the cells forming the walls of the excretory tubules. Carbon-14, introduced as l-phenylalanine-C-14, was concentrated in the same tissues, with the exception of the intestinal epithelium. These findings are discussed in relation to the function of the respective tissues.
