Abstract
A lipopolysaccharide (BP-LPS) isolated from killed Bordetella pertussis (Tohama strain) was determined to have low toxicity based on the mortality and decrease in body weight of BP-LPS-injected mice. BP-LPS, administered intradermally or intraperitoneally, clearly inhibited the growth of an MM46 murine mammary carcinoma. When compared with a toxic Escherichia coli-derived LPS, BP-LPS displayed excellent anti-tumour activity against MH134 hepatoma and Meth A fibrosarcoma. As part of a combined chemotherapy/immunotherapy regimen, BP-LPS also seemed to prolong the lifespan of mice inoculated with Lewis lung carcinoma. BP-LPS thus appears to have valuable characteristics as an anti-tumour agent.
