title: [Effects of Armillariella tabescens polysaccharide IPS-B2 on activity of mouse peritoneal macrophages and transcription of related gene].
abstract: OBJECTIVE
  To observe the effect of IPS-B2 on mouse peritoneal macrophages and the transcription of IL-1beta, IL-6, TNF-alpha and iNOS.
  
  
  METHODS
  ELISA method and Griess method were used to detect the effect of mouse peritoneal macrophages produce cytokines IL-1beta, IL-6, TNF-alpha and cytotoxic effectors NO. The transcription of IL-1beta, IL-6, TNF-alpha and iNOS was detected by real-time RT-PCR method.
  
  
  RESULTS
  IPS-B2 could not promote mouse peritoneal macrophage production, but it could significantly improve the IL-1beta, IL-6, TNF-alpha content in mouse peritoneal macrophages culture supernatant, and increase the gene expression of IL-1beta, IL-6, TNF-alpha and iNOS.
  
  
  CONCLUSIONS
  IPS-B2 can enhance the ability of peritoneal macrophages to excrete bioactive substances and promote the transcription of bioactive substances to antitumor.
