This study was carried out to determine the toxicity and biochemical morphophysiological changes caused by Serjania erecta leaf aqueous extract in pacu (Piaractus mesopotamicus). For acute testing (CL50-4h), juveniles were exposed during 4 h concentrations of 2.5, 12.5, 25, 50, 100, 150 µg mL-1, which added directly water tanks. In control group, animals kept free from extract. CL50-4 estimated...
La producción pesquera puede generar cantidades considerables de residuos cuya disposición final inadecuada causar daños ambientales. utilización estos desechos para la obtención productos con alto valor agregado y interés industrial, es una alternativa acuícola sostenible. En este trabajo se obtuvieron caracterizaron extractos ácidos ricos en enzimas tipo pepsina (EP) alcalinos tripsina (ET) a...
This work evaluated the acute inflammatory response induced by injections of 0.5 mL saline solution (control), 500 microg carrageenin and 0.5 mL thioglycollate 3% in the swim bladder of juvenile tambacu hybrid. Fish were distributed in three treatments, three replications and acclimated for a period of 10 days before assay. The cell characterization from the inflammatory exudate was performed i...
Objetive. This study was conducted to evaluate, by means of lectinhistochemistry (LHC), the expression of carbohydrates in granulomas induced by the bacillus Calmette-Guerin (BCG) in muscle tissue of Piaractus mesopotamicus after 33 days. Material and methods. Histological sections with 3 μm thick were incubated with the following lectins :WGA (Wheat germ agglutinin), DBA (Dolichos biflorus agg...
