摘要:
为研究环磷酰胺对断奶仔猪免疫抑制效果的影响,选取体质量一致、健康的杜×长×大、35日龄断奶仔猪40头,随机分为4个处理组,分别为:A对照组,不注射环磷酰胺;B试验组,连续3 d注射60 mg/kg环磷酰胺;C试验组,连续2 d注射90 mg/kg环磷酰胺;D试验组,一次性注射180 mg/kg环磷酰胺。试验7、14、21 d前腔静脉采血,用于血细胞检测。结果显示,与A组相比,B、C、D组平均日增质量显著降低(P<0.05),B、C、D组间无显著差异;B、C、D组7、14 d的血清白细胞和淋巴细胞数量显著低于A组(P<0.05);7 d时B、C、D组外周血CD3+、CD4+、CD8+ T细胞显著低于A组(P<0.05),14 d时外周血CD4+ T细胞数显著低于A组(P<0.05)。由此可见,总剂量为180 mg/kg的环磷酰胺可减少断奶仔猪白细胞和淋巴细胞浓度,抑制CD3+、CD4+、CD8+T细胞的成熟,具有免疫抑制作用,可用于构建仔猪免疫抑制模型。因一次性注射操作简便,在0~21 d内免疫抑制效果较稳定。因此,建议采用一次注射180 mg/kg环磷酰胺构建仔猪免疫抑制模型。
