| 5 | In vitro and in vivo trypanocidal action of aescin and aescin liposomes against Trypanosoma evansi in experimental mice显示文摘Objective:To verify the trypanocidal effectiveness of aescin and aescin liposomes against Trypanosoma evansi in vitro and in vivo.Methods:Aescin and aescin liposomes were used in vitro on trypomastigotes at different concentrations(0.5%,1.0%and 2.0%) and exposure times(0,1,3,6 and 9 h).In vivo tests were performed using mice as the experimental model.Trypanosome evansi infected mice were treated with aescin and aescin liposomes with doses of 60 and 100 mg/kg during 4 d.Results:The three concentrations tested in free form and nanoencapsulated showed trypanocidal activity in vitro,completely eliminating the parasites in small concentration after6 h of assay.Animals treated with aescin(100 mg/kg) and aescin liposomes(100 mg/kg)showed increase in longevity,however without curative effect.Conclusions:Active compounds present in natural products,such as aescin,may potentiate the treatment of trypanosomosis when used in association with other trypanocidal drugs. | Matheus Dellamea Baldissera Nathieli Bianchin Bottari Thirssa Helena Grando Roberto Christ Vianna Santos Ana Julia Figueiro Dalcin Patrfcia Gomes Renata Platcheck Raffin Carine Eloise Prestes Zimmerman Janio Morais Santurio Silvia Gonzalez Monteiro Aleksandro Schafer Da Silva | 2014 | Asian Pacific Journal of Tropical Biomedicine2014，4，12： | 0 |
