香菇多糖和黄芪多糖对vAMV感染雏鸡SOD活性的影响

３日龄肉用ＡＡ雏鸡禽成髓细胞性白血病强毒（ｖＡＭＶ）人工感染后，禽成髓细胞性白血病（ＡＭＢ）发病率８６．７０％、死亡率７０．００％，脾脏、胸腺、法氏囊、心脏、肝脏、肾脏及性腺超氧化物歧化酶（ＳＯＤ）活性与健康雏鸡相比，Ｔ－ＳＯＤ和Ｍｎ－ＳＯＤ活性于１０日龄时明显升高（Ｐ＜０．０１）、于１７日龄后则显著降低（Ｐ＜０．０５，Ｐ＜０．０１），而Ｃｕ，Ｚｎ－ＳＯＤ活性无显著变化（Ｐ＞０．０５）。ｖＡＭＶ感染雏鸡注射香菇多糖或黄芪多糖，ＡＭＢ发病率６７．５０％或６４．１０％、死亡率５５．００％或５１．３０％，同感染组相比，感染／香菇组的Ｔ－ＳＯＤ、Ｍｎ－ＳＯＤ及Ｃｕ，Ｚｎ－ＳＯＤ活性初期显著降低（Ｐ＜０．０５，Ｐ＜０．０１），中后期无显著变化（Ｐ＞０．０５）；感染／黄芪组的Ｔ－ＳＯＤ、Ｍｎ－ＳＯＤ活性初期显著降低（Ｐ＜０．０５），中后期明显高于感染组（Ｐ＜０．０５，Ｐ＜０．０１），而Ｃｕ，Ｚｎ－ＳＯＤ活性则无明显变化（Ｐ＞０．０５）。结果表明，黄芪多糖的促抗过氧化能力中后期优于香菇多糖。

EFFECT ON ACTIVITY OF SOD IN CHICKSINFECTED WITH vAMV AFTER INJECTIONWITH ASTRAGALAN AND LENTINAN

おhe AMB morbidity was 867%, AMB mortality was 700% and the activities of T-SOD and Mn-SOD in liver, kidney, heart, spleen, bursa of fabricius, sexual gland and thymus were very significantly increased (P<001) at 10 day-age and significantly decreased (P<005, P<001) after 17 day-age, but the activity of Cu, Zn-SOD didn′t significantly change (P>005) in the chicks infected with vAMV in contrast to the chicks of control groupThe AMB morbidity was 675% or 641%, AMB mortality 550% or 513% in the chicks both infected with vAMV and injected with Lentinan or Astragalan The activities of T-SOD, Mn-SOD and Cu, Zn-SOD in the fromer organs were significantly decreased (P<005), P<001) in the early days and didn′t significantly change in the middle-later days in the chicks both infected with vAMV and injected with Lentinan The activities of T-SOD and Mn-SOD were significantly decreased (P<005), in the early days and significantly increased (P<005, P<001) in the middle-later days, but the activities of Cu, Zn-SOD didn′t significantly change in the chicks both infected with vAMV and injected with Astragalan in contrast to the chicks infected with vAMV
