Histological Aspects Regarding the Antioxidant and Chelating Potential of Chlorella in Experimental Pb Contamination of Carassius gibelio Bloch species. II
The purpose of this study was to highlight the histological aspect of some tissue of Prussian carp’s specimens, subjected to sub lethal Pb intoxication with and without chlorella dietary supplementation. 90 Prussian carps, with weighing between 10 and 12 g were divided according to the following tre...

| Résumé: | The purpose of this study was to highlight the histological aspect of some tissue of Prussian carp’s specimens, subjected to sub lethal Pb intoxication with and without chlorella dietary supplementation. 90 Prussian carps, with weighing between 10 and 12 g were divided according to the following treatments for 21 days: C (without treatment), E1 (75 ppm Pb into water), E2 (75 ppm Pb into water+2% lyophilized chlorella in feed). Samples of gill, intestine, liver and kidney were removed at the end of experimental period and analyzed in light microscopy. QuickPHOTO Micro 2.2 software has been used for the histological study. Our findings are: obvious histological alterations have been observed in experimental Pb-poisoned group; active chlorella compounds cannot counteract the effects of Pb-induced oxidative stress on intestinal tissue; chlorella has been shown to be a weak Pb chelator on liver tissue; chlorella lyophilisate reduces to a small extent the toxic effects of the contaminant in the kidneys; respiratory barrier slightly affected in the group receiving chlorella in feed. |
