title: [Experimental studies on antitumor effects of lysozyme].
abstract: Effects of lysozyme(LY) alone and combination with various antitumor agents were examined using syngeneic tumors mainly Meth-A and MH 134 transplanted into Balb/c and C3H/He mice, respectively. The effects of LY on pulmonary metastases were also examined in BDF1 mice bearing Lewis lung carcinoma (3LL). LY inhibited the growth of Meth-A tumor and enhanced antitumor effects of mitomycin C (MMC). bleomycin (BLM) and 5-fluorouracil (5-FU), LY activated antitumor effects of MMC, BLM and 5-FU on MH 134 tumor, however, LY alone did not show any significant antitumor effect on it. The combination treatments using LY with MMC or 5-FU showed a marked inhibition on pulmonary metastases of 3LL. The pre-treatment of LY inhibited the tumor growth of Sarcoma-180 in ICR mice.
