title: [Effects of Xuanyinning Recipe on invasion of SPC-A-1 cells and pathomorphological changes of peritoneum in mice inoculated with sarcoma 180].
abstract: OBJECTIVE
  To observe the effects of Xuanyinning Recipe (XYNR) in inhibiting SPC-A-1 cellular infiltration and on the pathomorphological changes of peritoneum in mice inoculated with sarcoma 180 (S(180)).
  
  
  METHODS
  On the bases of isolated culture of mouse peritoneal mesothelial cells, we adjusted and added the human lung adenocarcinoma cell line SPC-A-1 into the double-layer culture medium to observe the number of clones formed. We also took out the peritoneum from the mice administered with three different dosages of XYNR and observed its pathomorphological changes with transmission electron microscope.
  
  
  RESULTS
  In the in vitro experiment, the number of clones of SPC-A-1 in culture medium with XYNR (50 microg/ml) decreased distinctly. In the in vivo experiment, it was observed that, in the peritoneum from the XYNR-treated mice inoculated with S(180), the mesothelial cells arranged more and more regularly with the increasing of the dosage of XYNR, while the mesothelial cells in the peritoneum of the mice in the control group necrosed and arranged loosely.
  
  
  CONCLUSIONS
  XYNR can inhibit the invasion of SPC-A-1 cells. It also can improve the loose arrangement of the peritoneal mesothelial cells in mice inoculated with S(180), so as to inhibit the malignant effusion.
