作者测定了实验动物巨噬细胞和无细胞灌洗液内生化成分正常值。结果表明巨噬细胞内乳酸脱氢酶(LDH)和酸性磷酸酶(ACP)活性较高,碱性磷酸酶(AKP)和N-乙酰神经氨酸(NA)含量很低,而无细胞灌洗液中LDH、ACP活性较低、AKP和NA含量很高。巨噬细胞内生化成分的正常值可以作为体外细胞培养评价环境毒物毒性作用的定量参比标准。 The authors determined the normal values ​​of biochemical components in macrophages and cell-free lavage fluid in experimental animals. The results showed that the activity of lactate dehydrogenase (LDH) and acid phosphatase (ACP) in macrophages was high, and the content of alkaline phosphatase (AKP) and N-acetylneuraminic acid (NA) was low, and no cell lavage was performed. LDH, ACP activity in the liquid is low, and the AKP and NA content is high. The normal values ​​of macrophage endogenous components can serve as a quantitative reference standard for assessing environmental toxic effects of cell culture in vitro.
