本研究用 Sprague-Dawley 大鼠气管体外诱与鸡胚皮肤接触培养的方法,通过倒置显微镜、光镜和扫描电镜观察了蟾酥的抑癌作用。结果表明:(1)诱发性大鼠气管癌变细胞,具有向鸡胚皮肤侵袭性生长的生物学行为。同时证明蟾酥对大鼠气管体外诱癌过程具有抑制作用。(2)蟾酥具有逆转大鼠气管上皮的异型性鳞状化生,促进气管受损粘膜的修复和保护气管上皮正常分化的作用。(3)在 MCA 作用下可见纤毛细胞增生和化生。
In this study, Spruague-Dawley rat tracheal in vitro induced embryo culture and skin contact methods, through inverted microscope, light microscopy and scanning electron microscopy observed the effect of simian cancer suppression. The results showed that: (1) Induced rat tracheocarcinoma cells have the biological behavior of invasive growth to chicken embryos. At the same time, it was proved that wolfberry has an inhibitory effect on rat tracheal extracorporeal carcinogenesis. (2) The eucalyptus has the effect of reversing the squamous metaplasia of the rat tracheal epithelium, promoting the repair of the damaged tracheal mucosa and protecting the normal differentiation of the tracheal epithelium. (3) The ciliated cell proliferation and metaplasia can be seen under the action of MCA.
