This study evaluated the in vitro and in vivo effects of the essential oil of Mentha piperita on monogeneans and its toxicity for Arapaima gigas. For the in vitro assay, gills of A. gigas naturally infected by Dawestrema cycloancistrium and Dawestrema cycloancistrioideswere exposed to 0, 80, 160 and 320 mgL?1 of M. piperita, which demonstrated anti-helminthic activity. In the toxicity test, A. gigas fingerlings were exposed to 0, 20, 40, 80, 100, 130 and 160 mg L?1 of M. piperita to determine the lethal concentration (LC50-4 h), which was found to be 38 mg/L. Fish that had been exposed to 80, 100, 130 and 160 mg L?1 presented epithelial elevations, fusion of the secondary lamellae, hypertrophy and aneurism. Necrosis was only observed at a concentration of 160 mg L?1 of M. piperita. The in vitro results demonstrated that the anti-helminthic activity of M. piperita against Dawestrema spp.was dose dependent. However, bathswith 40 mg L?1 of essential oil ofM. piperita were not effective against monogeneans in the gills of A. gigas. Therefore, since this anti-parasitic substance was in vitro effective and the concentrations used in the baths were not efficient and caused tissue alterations in the gills of the fish, other therapeutic strategies should be tested in order to increase the efficacy of this phytotherapeutic substance and reduce its toxicity for A. gigas. Finally, this study investigated the efficacy of M. piperita essential oil against parasites of A. gigas, for the first time.

As imagens de satélite estão cada vez mais difundidas no setor educacional devido a massificação da Internet e a utilização de novas tecnologias no processo de ensino-aprendizagem. Nas primeiras séries do ensino fundamental, a aquisição de conhecimentos a respeito do lugar de vivência do aluno (escola, bairro rural ou urbano) e das inter-relações desse lugar com o município (maior dimensão) é um passo importante no aprendizado e na compreensão das questões ambientais, as quais extrapolam os limites espaciais delimitados pelo homem. |
