摘要
用新城疫病毒(NDV)LD强毒株以肌肉注射方式感染21日龄麻鸡,于感染后1d、2d、3d、4d、5d采取脑、心脏、肺脏、脾脏、法氏囊等组织,分光度法测定其超氧化物歧化酶(SOD)的活性和脂质过氧化物丙二醛(MDA)的含量。结果显示,NDV感染组雏鸡的各组织中SOD活性在人工感染后2d显著低于对照组(p<0.05);雏鸡心脏、肺脏、脾脏、法氏囊MDA含量在人工感染后2d显著高于对照组(p<0.05),脑组织MDA含量在人工感染后3d显著高于对照组(p<0.05)。
To study the effect of Newcastle disease virus （NDV） infection on tissue anti-oxidation functions, 21-day-old chicken were experimentally infected with virulent NDV LD isolate, and tissue from brains, hearts, lungs, spleens, and bursa of fabricius were detected for SOD and MDA by spectro-photometry at 1, 2, 3, 4 and 5 days post-infection （DPI）, respectively. The results showed that the SOD activity of the tissues from the infection group was significantly lower than that of the control group on 2 DPI （p〈0.05）; while MDA amounts of the infection group was significantly higher than that of the control group on 3 DPI （p〈 0.05）.
