N-CWS(Nocardia rubra cell wall skeleton奴卡放线菌细胞壁骨架,作为免疫增强剂,可促进癌性胸水吸收和胸膜粘连,并可延长肺癌存活期。国内尚末见报道。我院在完成N-CWS对纯系小鼠抑瘤实验取得肯定效果之后,于1983年7月用于临床。共观察癌性胸水13例,癌性心包积液1例,疗效显著,现报告如下。对象选择及治疗方法一、对象选择:肺癌合并胸水和癌性心包积液均 N-CWS (Nocardia rubra cell wall skeleton) act as an immune enhancer, can promote the absorption of cancerous pleural effusion and pleural adhesions, and can prolong the survival period of lung cancer. There is no report in the country yet. Our hospital is completing N. After CWS had a positive effect on tumor-inhibitory experiments in pure mice, it was used clinically in July 1983. A total of 13 cases of cancerous pleural effusion and one case of cancerous pericardial effusion were observed, and the curative effect was significant. Treatment I. Object selection: lung cancer with pleural effusion and cancerous pericardial effusion
