title: [Analysis of the key factors in SCID mouse-human leukemia model].
abstract: OBJECTIVE
  This study was to explore the key factors in leukemia model through the analysis of mouse with bad life state in the modeling process of leukemia so as to provide the theoretical reference for improving the success rate of modeling.
  
  
  METHODS
  At 1 week after inoculation of leukemia cells into SCID mice, the life status and peripheral hemogram of SCID mice were tested, the bone marrow smears, splean biopsy and spleen index of mice were examined after dissecting mormal and agoned/died mice during modoling, and the examined results were compared.
  
  
  RESULTS
  As compared with control mice, the life status of experimental mice was poor; the blood smear test showed juvenile cells, slightly more white blood cells with irregular shape and partial rupture, the lymphocytes and band cells obviously increased, the neutrophile granulocytes showed nuclear left shift; the bone marrow smears showed larger cell volume, smaller mulcoplasm, abnormal morphology of cells and cell nuclei and serious cell rapture; the spleen examination showed that the spleen diplayed enlargement and hyperemia to varying degree, the spleen index obviously increase, the spleen interstitial expansion, cell disordered arragement and irregular cell shope were observed, however there was no infiltration of leukemia cells in control and experimental mice.
  
  
  CONCLUSIONS
  The mouse age, pathway of inoculating the leukemia cells, sterile condition in breading and avoiding the rejection and inflammatory response in modeling process are the key foctors influencing the modeling success.
