The biological activity of a preparation of heat killed cells of Enterococcus faecalis, FK-23 which was isolated from the feces of a healthy human, was investigated in C3H/He mice. Intraperitoneal injection of the preparation caused an accumulation of neutrophils and macrophages in the peritoneal cavity of the mice 6 h later. As a parameter of the activation of macrophages, the effect of the FK-23 preparation on the production of tumor necrosis factor (TNF) was examined. The mice were given two consecutive intravenous injections of the preparation at a dose of 10μg/mouse and, 3 h later, of 300μg/mouse. The TNF level in the sera reached 99 U/ml in mice 2 h after the second injection. This preparation also stimulated peritoneal macrophages to produce TNF in vitro and increased the capacity of neutrophils to adhere to plastic plates and to release active oxygens, but did not induce blastogenic transformation of lymphocytes. These results suggest that the FK-23 preparation is a biological response modifier (BRM) with various activities on phagocytes similar to a streptococcal antitumor agent, OK432.

Tumor necrosis factor-α (TNF-α), a cytokine secreted by macrophages, was recently recognized as an important molecule in host defense mechanism. However, its overproduction is also implied in many acute and chronic disease states. The inhibition of TNF-α overproduction, therefore, leads to suppression of acute and chronic inflammation. This work was undertaken to ascertain whether vegetable juice from perilla leaf, which may be a new candidate for an antiinflammatory reagent, can inhibit the endogenous production of TNF-α in mice.Both red and green perilla juice significantly inhibited TNF-α production byperos administration. Perilla juice showed nearly the same level of an inhibitory activity against TNF-α production as did Saibokuto, an antiinflammatory reagent. The inhibitory activity was stable for heat treatment (100°C, 10 min) . Perilla contains an active molecule (s) which can inhibit a host from releasing TNF-α. This molecule thus may suppress host defense systems as well as antiinflammatory drugs such as glucocorticoid or Saibokuto.

The present study shows that some selected anti-cancer drugs induce tumor lysis in vitro in cooperation with phagocytic cells (drug-dependent cellular cytotoxicity ; DDCC) and that chemotherapeutic drugs augment the mediator-dependent killing activity of macrophages. Tumor cells pretreated with the drugs were susceptible to phagocytemediated killing. Tumor necrosis serum can also cooperate with some drugs in killing tumor cells. Moreover, some selected drugs can induce cytotoxic macrophages and the quantitative changes of phagocytes such as polymorphonuclear leukocytes. These results suggest that some anti-cancer drugs have the activities of inactivation of tumor cells and/or activation of host cells. Thus, tumor cells may be killed effectively in vivo by anti-cancer drugs through these mechanisms.

The antitumor activity of a preparation of heat-killed cells of Enterococcus faecalis, FK-23. Intraperitoneal injection of the preparation prolonged the lifespan of C3H/He N mice which were intraperitoneally inoculated with MM46 mammary carcinoma. Not only intraperitoneal but also oral administration of the FK-23 preparation inhibited the growth of these carcinomas inoculated intradermally. The tumor-bearing mice produced tumor necrosis factor (TNF) in their sera 2 h after intravenous injection of OK432. This TNF level increased after the mice were fed with food supplemented with the FK-23 preparation. Additionally, the FK-23 preparation inhibited the growth of Meth A fibrosarcoma in cyclophosphamide-treated BALB/c mice.

We previously demonstrated that Amaryllidaceae alkaloids, lycorine and lycoricidinol, inhibit induction of apoptosis by calprotectin derived from neutrophils, and that the latter alkaloid showed suppression in rat adjuvant-induced arthritis model. These findings suggest that the alkaloids have a modulating activity against inflammatory reaction. To explore further the mechanism of the suppression for inflammation, we studied the effect of the alkaloids on macrophage tumor necrosis factor(TNF-α) production in vitro, since TNF-α is recognized as a pivotal cytokine to regulate inflammation. As a result of this study, lycorine and lycoricidinol inhibited TNF-α production of murine macrophages stimulated with lipopolysaccharide(ID_<50> were 0.2μg/ml and 0.002μg/ml, respectively). The inhibition was also observed in macrophages treated by Gram-positive bacteria, Enterococcus faecalis. Both lycorine and lycoricidinol reportedly have inhibitory activity for protein biosynthesis. Although the inhibition of TNF-α production by lycoricidinol was mainly due to the inhibition of protein biosynthesis, lycorine showed inhibition against TNF-α prodictuon at lower concentrations than the case that they inhibited ^<35>S-Cysteine/^<35>S-Methionine incorporation into macrophages. These facts sugges that the inhibition of TNF-α production is not due to the inhibitory activity against protein translation at least at lower concentrations. From these results, it was concluded that these alkaloids exert inhibitory effects not only on neutrophil apoptosis-inducing protein, calprotectin, but also on macrophage TNF-α production.
