最近 ,美国的一项研究证明尼古丁可促进肿瘤增长 ,这一发现引起了对长期使用尼古丁替代品辅助戒烟的质疑。研究人员评估了尼古丁和 4 甲基亚硝基氨 3 吡啶 1丁酮(NNK)对正常人支气管上皮细胞和小支气管上皮细胞的生物化学影响。以早期的显示吸烟者的肺癌细胞内激酶是有活性 Recently, a study in the United States proved that nicotine promotes tumor growth, a finding that raised questions about the long-term use of nicotine substitutes to help stop smoking. Researchers evaluated the biochemical effects of nicotine and 4-methylnitrosamine 3-pyridine-1-butanone (NNK) on normal human bronchial epithelial cells and bronchial epithelial cells. In early lung cancer cells, kinases that show smokers are active
