The levels of N-acetyl-beta-glucosaminidase (NAGase) and acid phosphatase were analysed in tissue from the teat and lactiferous sinus epithelia of dairy cows at different stages of lactation. Enzyme levels were lower in the epithelia of the teat sinus than of the lactiferous sinus. For both enzymes, levels were highest in tissue from post-partum glands, lowest in those from dry and mid-lactation glands. In involuting glands the levels were high, but not as high as the post-partum glands.
对处于不同泌乳阶段的奶牛乳头和输乳窦上皮组织中的N-乙酰-β-葡萄糖苷酶(NAGase)和酸性磷酸酶水平进行了分析。乳头窦上皮中的酶水平低于输乳窦上皮中的酶水平。对于这两种酶,产后腺体组织中的水平最高,干奶期和泌乳中期腺体组织中的水平最低。在退化腺体中,酶水平较高,但不如产后腺体中的高。
