Subjects
cadmium, Carassius auratus, catabolic ammonia
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

Leptin is a modulator of food intake and energy homeostasis both in mammals and in some species of nonmammals vertebrates. In this study, we reported for the first time, using an immunohistochemical and immunochemical approach, the presence and distribution of immunoreactivity to leptin-like protein in the gastroenteric tract of Dicentrarchus labrax (bass) and Carassius auratus (goldfish), two teleostean species with different feeding and different adaptative morphological organization of the gastroenteric tract. Bass stomach showed intense immunoreactivity to leptin-like protein in all regions, with immunoreactive cells located at the base of the mucosal plicae and at the apical margin of the gastric crypts. Immunoreactive fibers and neuronal cells were observed close to vascular structures in the pyloric region. In bass and goldfish intestine, rare immunoreactive cells were observed along the mucosal epithelium mostly at the base or the apex of intestinal folds in the proximal and medium intestine; numerous immunoreactive nerve fibers in the circular and longitudinal layers of the tunica muscolaris as well as in the myenteric plexus were observed. Western blot analysis recognized a ∼15 kDa signal with a similar expression pattern for goldfish and sea bass. Our results could contribute to confirm the evolutive conservation of leptin-like proteins and their probably precocious functional diversification in fish. Microsc. Res.
