医药科学 致癌性 Conclusion: We presume that nickel and chrome and any other metals released from Ni-Cr alloy prosthetic restoration may cause inflammation and have carcinogenicity to the gingival tissue. 研究结论:本实验检测COX-2、HSP60和HSP70在镍铬合金修复体患者牙龈组织中的表达,发现这三种指标均有过表达。 证明在一定时间内,即使不是过敏体质和金属过敏者,镍铬合金修复体可以刺激牙龈发生炎症反应,并有致癌性的潜在可能。 致癌活性 致癌力

农业科学 致癌性 Their overuse may cause anaphylactic reaction and increase their carcinogenicity. Therefore, more attention was paid to their harm to human healthy and potential pollution to environment due to their residues in animal food. 然而过量使用会引起人过敏性反应,且可能有致癌性,因此在动物性食品中残留引起生态环境污染和人类健康危害的潜在威胁已倍受关注,而磺胺二甲基嘧啶(SM2)在磺胺类药物的使用中占有很大比例。 致癌
