根据我国传统中医药理论及现代分子生物学知识，设计并配制了具有抗肿瘤效应的复方中草药合剂ＮＫＣ－１．体外实验表明：ＮＫＣ－１能够选择性杀死ｒａｓ癌基因诱导的转化细胞，在较低浓度条件下对转化细胞的恶性行为有一定的抑制和逆转作用。急性毒性实验结果显示：当注射剂量为０．８ｍｌ／只昆明鼠时，仍无严重毒性。裸鼠体内实验表明：ＮＫＣ－１具有良好的抑制肿瘤效应。 According to traditional Chinese medicine theory and modern molecular biology knowledge, compound Chinese herbal medicine NKC-1 with anti-tumor effect was designed and formulated. In vitro experiments show that NKC-1 can selectively kill transformed cells induced by ras oncogenes, and at a lower concentration, it can inhibit and reverse the malignant behavior of transformed cells. The results of acute toxicity test showed that when the injection dose was 0.8ml/Kunming mice, there was still no serious toxicity. Experiments in nude mice showed that NKC-1 has a good tumor suppressor effect.
