TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['To determine whether inflammatory cytokine production by stimulated human alveolar macrophages is affected by perflubron exposure.', 'Controlled laboratory investigation of alveolar macrophage function in vitro.', 'Research laboratory.', 'Cultured alveolar macrophages obtained by bronchoalveolar lavage from eleven normal volunteers.', 'Endotoxin-stimulated alveolar macrophages were treated with perflubron.', 'Alveolar macrophages were stimulated for 1 hr with lipopolysaccharide and then treated with perflubron for 23 hrs. Cell-free supernatants were collected and cytokines were assayed by enzyme-linked immunosorbent assay. Tumor necrosis factor-alpha, interleukin-1, and interleukin-6 were stimulated by lipopolysaccharide (endotoxin) and all of these cytokines were significantly (p < .05) inhibited by perflubron. Cell viability was not affected by perflubron. Basal cytokine concentrations from unstimulated alveolar macrophages were not altered by perflubron.'] Does perflubron decrease inflammatory cytokine production by human alveolar macrophages?
OUTPUT:

agent
yes
