Alterations in murine host defense functions by adriamycin or liposome-encapsulated adriamycin.

Peritoneal exudate cells (PEC) from C57BL/6 mice were collected on different days following an i.p. injection of Adriamycin (10 mg/kg) as free drug (ADM) or encapsulated in multilamellar liposomes (ADM/Lip).

Effect of recombinant tumor necrosis factor on tumoricidal activation of murine macrophages: synergism between tumor necrosis factor and gamma-interferon.

The activation of tumoricidal murine macrophages by recombinant human tumor necrosis factor (rH-TNF) alone or in combination with recombinant murine gamma-interferon (rM-IFN-gamma) was examined. When used alone, rH-TNF (10(-1)-10(5) units/ml) did not induce macrophage tumoricidal activity against TNF-insensitive P815 mastocytoma cells. Combining rH-TNF with rM-IFN-gamma resulted in the synergistic induction of tumoricidal activity in resident peritoneal macrophages.

Effect of recombinant human tumor necrosis factor on the induction of murine macrophage tumoricidal activity.

The ability of recombinant human tumor necrosis factor (rH-TNF) alone or in combination with lymphokines (LK) to induce the in vitro activation of murine macrophages was evaluated. The treatment of C57BL/6 mouse resident peritoneal exudate cells (PEC) with rH-TNF and LK was found to induce the activation of macrophages to a tumoricidal state against P815 mastocytoma cells. Neither rH-TNF nor LK alone induced macrophage cytotoxic activity.

Effects of platform fashion shoes on brake response time.

The purpose of the present investigation was to examine the effects of 'platform' fashion shoes on response time in vehicle braking. Seventeen subjects participated in two test sessions: in one they wore platform shoes and in the other normal footwear. Although all subjects were accustomed to wearing either type of footwear, platform shoes significantly slowed their braking responses, compared with normal shoes (0.
