Description
Abstract
The gut of Pantex, a sparid hybrid fish
(Pagrus major x Dentex dentex) with a great potential
importance for the Italian aquaculture, was histochemically
and immunohistochemically investigated in
order to evidence components of the intramural nervous
and diffuse endocrine systems. The general structural
aspects of the intramural nervous system were shown by
the Nissl-thionin staining. As in most other fish, it was
only organized in the myenteric plexus. Acetylcholinesterase
(AChE) activity was observed in both
nerve cell bodies and terminals al1 along the gut. The
NADPH-diaphorase reactivity too, possibly linked to the
synthesis and release of nitric oxide, was present in
nerve cell bodies and nerve terminals of the oesophagus,
stomach and intestine. In addition, the intramural
nervous system was shown to contain Trk (tyrosinekinase)
receptors for neurotrophin, as evidenced by Trk
A-, Trk B- and Trk C-like immunoreactivities, thus
suggesting an involvement of neurotrophin in the
function of this system. Trk B- and Trk C-like
immunoreactivities were detected in epithelial endocrine
cells, too. The additional presence of serotonin- and metenkephalin-
like immunoreactivities in numerous
endocrine cells in the epithelial layers of the stomach
and intestine was showed.
