沙尘暴应激对荷斯坦牛红、白细胞及红细胞黏附免疫功能的影响

The Influence of Sandstorm Stress on RBC,WBC and the RBC Adhesion Immune Function of Holstein Cows

在春夏之交沙尘暴多发季节,为初步了解沙尘暴对奶牛的影响,在沙尘暴期间和前后随机抽取6头荷斯坦牛,用经典红、白细胞计数、白细胞分类计数及红细胞黏附免疫功能检测方法,检测红、白细胞数及红细胞黏附免疫功能的变化。结果表明,沙尘暴期间红、白细胞总数有所增高;中性粒细胞极显著增多;淋巴细胞却显著下降;C3bR和ICR的受体花环率略有减少。说明沙尘暴所导致的环境低氧使奶牛增加红细胞数以应付缺氧的环境;中性粒细胞为吞噬沙尘颗粒清除异物极显著提高,而具有特异性免疫作用的淋巴细胞却显著下降;同时红细胞黏附免疫功能也有所下降。可见沙尘暴使炎症细胞聚集,特异性免疫细胞显著下降,很可能导致炎症发生。

The sandstorms occurred repeatedly at the dawn of summer in the Inner Mongolia region. In order to learn the influence of sandstorm on cow, RBC, WBC, differentiate count of leukocyte and erythrocyte adhesion immune function were checked on 6 random Holstein cow during, before and after sandstorm with traditional method. The result showed that the total number of red blood cells and white blood cell all increased during sandstorms; neutrophils increased significantly; lymphocyte decreased significantly; the receptor rate of C3bR and ICR decreased. In cows, red blood cells increase for responding the hypoxic environment caused by sandstorm; neutrophils increased significantly for engulfing and cleaning the sand granule; but the specific immunity of lymphocyte dropped significantly; erythrocyte adhesion immune function also dropped. The results indicated sandstorm led to inflammatory cells gathered and made specific immunity of lymphocyte dropped, so it may caused inflammatory.
