title: [Study on the level of soluble interleukin-2 receptor, expression of membrane interleukin-2 receptor and T lymphocyte subpopulations in pulmonary tuberculosis].
abstract: OBJECTIVE
  To evaluate the significance of soluble interleukin-2 receptor (sIL-2R), membrane interleukin-2 receptor (mIL-2R) and T lymphocyte subpopulations in development of pulmonary tuberculosis.
  
  
  METHODS
  The level of sIL-2R, expression of mIL-2R and the profile of T lymphocyte subpopulations in patients with pulmonary tuberculosis were tested by sandwiched ELISA and alkaline phosphatase-antialkaline phosphate (APAAP) methods.
  
  
  RESULTS
  The levels of sIL-2R, CD8 were higher, and expression of mIL-2R, CD4, CD4/CD8 ratio were lower in pulmonary tuberculosis than those in normal controls (P < 0.001). And the changes of all indicators in patients with cavitation were more obvious than those in patients without (P < 0.001), the changes in progressive stage were more obvious than those in stable and improving stages (P < 0.001).
  
  
  CONCLUSIONS
  The results indicated that the patients, condition and prognosis of pulmonary tuberculosis were related to the changes of sIL-2R level, mIL-2R expression and T lymphocyte subpopulations.
