Abstract

Histochemical changes of oxidative enzymes and cadmium uptake in the Carassius auratus gills were examined up to 7 days after a 87.6 mu M cadmium exposure in very alkaline water in the presence and absence of catabolic ammonia. In the presence of catabolic NH3, the toxic action of cadmium is much more intense and determines a 20% survival of goldfish with a heavy increase in the excretion of mucus. Animals treated with cadmium only and controls survived in the order of 100%. More drastic histochemical alterations in the activity of oxidative enzymes (SDH, G-6-PDH, LDH) were documented in animals treated both with cadmium and ammonia, if compared with those treated with cadmium only. A reduction in the activity of enzymes after 24 h, a heavy increase of the LDH reaction after 72 h, and a strong increase after 7 days in the number of positive SDH cells (which correspond to chloride cells) were documented. After a hyperaccumulation at 24 h (returning afterwards to much lower values), at 7 days the cadmium uptake was higher in the animals treated both with cadmium and ammonia.

Abstract

KEY WORDS ghrelin; Carassius auratus; Dicentrarchus labrax; immunohistochemistry;gastrointestinal tractABSTRACT The occurrence and localization of ghrelin peptide in the gastrointestinal tract ofCarassius auratus and Dicentrarchus labrax, two fish species that exhibit different feeding behav-ior, different habitats, and different anatomical organizations of the gastroenteric tract, wereexamined by immunohistochemical methods and western blotting analysis. All of the gastrointesti-nal segments studied displayed immunohistochemical localizations of ghrelin peptide. Numeroussingle or clustered immunoreactive cells were found along the gastric folds, particularly in the py-loric region of Dicentrarcus labrax, whereas scattered ghrelin immunoreactive cells were observedin the intestinal epithelium of both fish species. Double immunolabeling PGP 9.5/ghrelin demon-strated the localization of ghrelin peptide also in nerve fibers and neuronal cells of the submucosaland myenteric plexuses, often in association with vascular structures. Western blotting analysisconfirmed the presence of ghrelin peptide in the gatrointestinal tract of both species studied, whosemolecular weight was similar to that of the corresponding mammalian prepro-ghrelin. The findingscould support the hypothesis that this peptide is an important appetite regulator in fish and couldconfirm the presence of the ghrelin peptide, starting from its precursor proteins, in the gastrointes-tinal tract of the goldfish and the sea bass.
