In the present study, the efficiency of the administration of doramectin (DOR) and DOR+vitamin AD3E (VIT), and the influence of these agents on oxidative stress parameters in rabbits infested by Psoroptes cuniculi (P. cuniculi) were investigated. DOR (200 microg/kg) and DOR (200 microg/kg)+VIT AD3E were administered to infested rabbits intramuscularly (IM). The administration of DOR and DOR+VIT improved the healing of ear lesions on day seven. Increase in the plasma malondialdehyde (MDA) level and erythrocyte catalase (CAT) activity, and decrease in glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) activities were determined in infested rabbits. In the rabbits which were administered DOR+VIT, plasma MDA levels decreased, and erythrocyte GSH-Px and SOD activities increased on day seven. In conclusion, DOR and DOR+VIT combination were effective against P. cunuculi infestation. Infestation stimulated oxidative stress. VIT treatment resulted in antioxidant activity against oxidative stress induced by P. cuniculi infestation.
在本研究中,研究了多拉菌素(DOR)和多拉菌素+维生素AD3E(VIT)的给药效率,以及这些药物对感染兔痒螨(P. cuniculi)的家兔氧化应激参数的影响。将DOR(200微克/千克)和DOR(200微克/千克)+VIT AD3E肌肉注射(IM)给受感染的家兔。在第7天,DOR和DOR+VIT的给药改善了耳部病变的愈合。在受感染的家兔中,测定了血浆丙二醛(MDA)水平升高、红细胞过氧化氢酶(CAT)活性升高,以及谷胱甘肽过氧化物酶(GSH-Px)和超氧化物歧化酶(SOD)活性降低。在给予DOR+VIT的家兔中,第7天时血浆MDA水平降低,红细胞GSH-Px和SOD活性增加。总之,DOR和DOR+VIT组合对兔痒螨感染有效。感染刺激了氧化应激。VIT治疗产生了针对兔痒螨感染诱导的氧化应激的抗氧化活性。
