Resumen: Fueron utilizadas 14 hembras ovinas, subdivididas en 2 grupos. El Grupo 1 sometido a dos aplicaciones de PGF2? y, el Grupo 2 tratado con CIDR insertado por 14 días siendo que, en el momento de la retirada, se administraron 500 UI de eCG. Las ovejas fueron monitoreadas por medio de ultrasonido. Desde el día anterior a aplicarse la segunda dosis de PGF2? [G1] y desde la administración de eCG [G2] hasta el décimo día del ciclo estral, fueron recogidas muestras de sangre para análisis de P4. La sincroniza-ción del estro y de la ovulación utilizando CIDR + 500UI de eCG, aumentó el diámetro máximo [p<0,05] y la tasa de crecimiento del folículo dominante [p<0,001] de la primera onda folicular. [Follicular dynamics of first-wave in ewes treated with prostaglandin [PGF 2alpha] vs. CIDR followed by 500 UI of ECG]. Abstract: Fourteen ewes were used and subdivided in 2 groups. Group 1 was synchronized by 2 i.m. injections of PGF2? and, Group 2 was treated for 14 d with CIDR and 500 IU of eCG at dispositive withdrawal on day 14. Ovarian follicular dynamics were ultrasonically monitored. Blood samples for P4 determination were collected daily from 1 d before of first injection of PGF2? until day 10 after ovulation. The CIDR + eCG treatment enhanced the maximum diameter [p<0,05] and growth rate [p<0,001] of dominant follicle during wave 1. |

Conteúdo: |
Monogeneans are ectoparasites that may cause losses in production and productivity in the aquaculture of Colossoma macropomum. Chemotherapeutics used in aquaculture usually have major adverse effects on fish; hence, the use of essential oils has been considered advantageous, but these are not soluble in water. Thus, the use of nanostructures to enhance water solubility of compounds and improve bioactivity may be very promising. This study investigated the antiparasitic activity of nanoemulsion prepared with Copaifera officinalis oleoresin (50, 100, 150, 200 and 300 mg/L), against monogenean parasites from the gills of C. macropomum. The particle size distribution and zeta potential suggested that a potentially kinetic stable system was generated. The nanoemulsion from C. officinalis oleoresin achieved high efficacy (100%) at low concentrations (200 and 300 mg/L) after 15 min of exposure. This was the first time that a nanoemulsion was generated from C. officinalis oleoresin using a solvent-free, non-heating and low-energy method. Moreover, this was the first time that an antiparasitic against monogeneans on fish gills, based on nanoemulsion of C. officinalis oleoresin, was tested. |
