[Effects of recombinant human interferon-alpha A/D on the growth of experimental tumors in mice].

The effects of recombinant human interferon-alpha A/D (rIFN-alpha A/D, a subtype of recombinant human leukocyte interferon with biological activities against murine tumor cells) on the growth of murine tumors were studied. rIFN-alpha A/D significantly inhibited the growth of mouse M5076 reticulum cell sarcoma, MOPC-104E myeloma, colon carcinoma 26 and Meth A fibrosarcoma by dose-dependent fashion. rIFN-alpha A/D also inhibited the metastases and growth of Lewis lung carcinoma and showed a synergistic effect with combination of cyclophosphamide. The antitumor activity of rIFN-alpha A/D was observed by intra-muscular, intravenous, subcutaneous, intraperitoneal injections or by the injection at the site of the tumors.
