Walther氏(1948年)认为在人类尚无瘤细胞穿过肺毛细血管的证据。Foulds氏(1932年)曾用Brown-Poarce兎癌作静脉注射后,观察到除肺、肝外其他脏器亦有转侈。又Zeidman氏(1952年)曾用Brown-Pearce和V_2二种兎癌注入兎耳静脉,发现前者的瘤细胞穿过肺能力远大于后者。为了澄清这个问题,本室进行了以下实验。 Walther’s (1948) thought there was no evidence of the passage of tumor cells through the pulmonary capillaries in humans. After Foulds’s (1932) intravenous injection of Brown-Poarce cancer was observed, except for the lungs and other organs outside the liver. Zeidman’s (1952) once used the Brown-Pearce and V2 cancers to inject into the ear vein, and found that the tumor cells in the former had a greater capacity to pass through the lung than the latter. In order to clarify this issue, the following experiments were conducted in this room.
