A critical analysis was made as to whether changes in morphology and histomorphology of fish intestinal mucosa could be appropriate for rapid application in field monitoring programs for heavy metal pollution. Equivalent gut samples of the gold grey mullet Liza aurata from different polluted environments were simultaneously treated using...

A new receptor neuron (RN) type was recently described in bony fish olfactory epithelium (OE): the crypt receptor neuron. This name is due to its main feature: the presence, at the apical part, of a deep invagination into which cilia protrude. The presence of this receptor neuron type is well documented in different species of bony fishes but...

In the present paper, the effect of natural environment non- lethal heavy metal concentration on cell renewal of Liza aurata intestinal epithelium, was studied by the TUNEL (ter- minal deoxynucleotidyltransferase-mediated dUTP nick end labelling) method and anti-PCNA (proliferating cell nuclear antigen) immunohistochemistry, in order to detect,...
