[The effects of small dosage inactivated BCG vaccine on cellular immune function of pulmonary chronic obstructive disease patients with deficiency of lung-qi].

UNLABELLED
To investigate the effects of the small dosage inactivated BCG vaccine on the cellular immune function of the patients suffered from pulmonary chronic obstructive disease with deficiency of the Lung-Qi, the authors observed the patients' immune function before and after BCG treatment for half a year.


RESULTS
The peripheral blood T lymphocytes subsefs (CD3, CD4, CD8, CD4/CD8) and the conversion ratio of lymphocyte of the patients both were significantly lower than those of the healthy people (P < 0.01). But after the treatment of the small dosage inactivated BCG vaccine for half a year, these parameters of the patients were improved (P < 0.01 or P < 0.05). It indicated that the small dosage inactivated BCG vaccine could improve the damaged cellular immune function.
