[Effect of components of dang-gui-bu-xue decoction on hematopenia].

Objective: To investigate the effects and the related mechanisms of the components of Dang-Gui-Bu-Xue decoction (DGBXD) on improving blood deficiency.

Method: The effects of promoting hematopoietic function were observed with the blood difficient model mice, by giving components of DGBXD. RBC, WBC, reticulocytes and bone marrow nucleated cells (BMNC) were determined.

[Comparative study of tissue cultured Dendrobium protocorm with natural Dendrobium candidum on immunological function].

Objective: To compare the immunological function and acute toxicity of the tissue cultured protocorm from Dendrobium candidum with natural medicinal materials from Dendrobium candidum.

Methods: The effect on immunological function was examined by counting white blood cells, weighing the weight of immune organs, and using carbon granules clearance and lymphocyte transformation test in mice treated with cyclophospamide. The acute toxicity was studied by giving maximum tolerated dose.
