Milligrams or less of tar& condensed smoke containing many chemicals, including some that cause cancer; 8毫克或少于此量的焦油&一种凝固起来的烟垢,含有许多化学成份包括引起癌症的化学成份;
However, it is tar that causes cancer. 然而,导致癌症的正是焦油。
Objective: To investigate the expression of mage-a mRNA in lung cancer tissues of mice induced by coal tar pitch ( CTP) fume and to discuss the above model for lung cancer immunotherapy with mage-a. 目的:探讨煤焦沥青(CTP)烟气诱发小鼠肺癌组织中黑素瘤抗原-a(mage-a)基因mRNA的表达及其意义。
Expression of melanoma antigen-a mRNA in coal tar pitch-induced lung cancer tissues in mice 黑素瘤抗原-a基因在煤焦沥青烟气诱发小鼠肺癌组织中的表达及其意义
The characteristics of coal tar pitch-induced rat lung cancer were as follows: 1. All occurred in the periphery of both lungs; 煤焦沥青诱发的大鼠肺癌的特征如下:1.癌肿全都发生在肺的周边部位;
