摘要
为了深入研究酮病的发生机理,选择荷斯坦奶牛作实验动物,应用酮粉法和改良式水杨醛比色法随机检测分组,Ⅰ组为10头阳性牛、Ⅱ组为10头对照牛。应用硝酸还原酶法测定血清中一氧化氮(NO)含量和一氧化氮合酶(NOS)活性。实验结果表明对照组奶牛血清中的NO含量及NOS活性均显著大于阳性组。由此可知,酮病可导致奶牛血清中NO含量降低、NOS活性下降。
In attempt to study the mechanism of Ketosis, the holstein dairy cows were randomly divided into two groups according to the ketone bodies powder method and improvemental salicylaldehyde colorimetric method, groupⅠ(n=10)was the experimental, groupⅡ(n=10)was control. NO content and NOS activity in serum was measured with nitric reductase method. The results showed that the NO content and the NOS activity in groupⅡwas significant higher than that in groupⅠ.Therefore the NO content and the NOS activity in serum are descended caused by Ketosis.
