本文分别对正常和慢性炎症人牙髓组织各１５例、急性炎症牙髓组织５例，进行Ｃｕ，Ｚｎ─ＳＯＤ活性测定。。结果显示，Ｃｕ，Ｚｎ─ＳＯＤ活性均数，正常牙髓为１５１．０３±５８．３４Ｕ／ｇ（湿重），慢性炎症牙髓为１２１．７２±７７．９６Ｕ／ｇ（湿重），急性炎症牙髓为２１３．２８±４６．５７Ｕ／ｇ（湿重）．提示Ｃｕ，Ｚｎ─ＳＯＤ活性在慢性炎症牙髓组织中比在正常牙髓中显著降低（ｐ＜０．０５），而在急性炎症牙髓组织中则比正常牙髓显著升高（ｐ＜０．０１）。这为研究急、慢性牙髓炎ｃｕ，Ｚｎ─ＳＯＤ活性变化规律提供了依据。
In this paper, 15 cases of normal and chronic inflammatory human dental pulp tissue, 5 cases of acute inflammatory pulp tissue, Cu, Zn ─ SOD activity determination. . The results showed that the average activity of Cu and ZnSOD was 151.03 ± 58.34U / g (wet weight) in normal dental pulp, 121.72 ± 77.96U / g (wet weight) in chronic inflammatory pulp, acute Inflammatory dental pulp was 213.28 ± 46.57 U / g (wet weight). It is suggested that the activity of Cu and Zn-SOD is significantly lower in chronic inflammatory pulp than in normal dental pulp (p <0.05), but higher in acute inflammatory pulp than normal pulp (p <0 .01). This provides a basis for studying the changes of Cu and Zn-SOD activity in acute and chronic pulpitis.
