DBQYD remarkedly improved the involvement of lym-phocytic 3H -TdR in mice of Yin deficiency and Yang-deficientcy

remarkedly stimulated the secretion of interleukin -2 （IL - 2） from lymphocytes of mice with Yin and Spleen deficiencies; remarkedly stimulated the production of colony stimulating factors （CSFs） in splenic culture medium （SCM） in deficient spleen mice

but markedly inhibited the formation of CSFs in lung culture medium of deficient spleen mice. The results demonstrated that

when benefitting methods were applied to both Qi -blood and Yin- Yang

the cellular immunity of mice with Yin -deficiency

Yan-deficiency and spleen deficiency

and the marrow hemopoietic function in mice with Yang and spleen deficiencies can be strengthened.
