Abstract:
AIM: To study the activation effects of maize pollen polysaccharides(PPM) on human thoracic cavity macrophage (hTM). METHODS: Activities of lactate dehydrogenase(LDH) and acid phosphatase (ACP) in the hTM were detected by automatic biochemical analyzer, and the level of tumor necrosis factor alpha(TNF-?) and interleukin-6(IL-6) in the hTM was analyzed by radioimmunoassay, after hTM were cultured with 0.312,0.625, 1.250, 2.500, 5.000 mg/mL PPM-RPMI 1640 for 24 and 48 hours in vitro. RESULTS: The activities of LDH and ACP increased in the hTM induced by PPM, and the levels of TNF-? and IL-6 in the hTM induced by PPM increased markedly too. And the induced expression effect of TNF-? and IL-6 is associated with the concentration of PPM, and time for PPM inducing. CONCLUSION: PPM can induce cytokines secretion in hTM,and activate hTM in vitro.
