By adopting the single method of immune agar -diffusion

the values of 12 items of plamal protein in 70 cases of chronic cor pulmonale receiving Huangqi Wuwu Decoction therapy were examined before and after the treatment with another 70 cases suffering the same disorder and receiving no TCM treatment as the control group. Results showed that the clinically effective rate of the treatment group was 90%. while that of the control group

75. 7%

with significal difference （P < 0. 05）. In the treatment group

the prealbumin

transferrin

fibrin conjugated protein were all markedly increased before and after the treatment; the C reactive protein

ceruloplasmin

α -antitrypsin

α - acid glycoprotein were all markedly decreased

（P<0. 001）. While in the control group

only ceruloplasmin

C - reactive protein were lowered markedly

indicating that the Decoction can raise the therapeutic effectiveness of cor pulmonale

regulate the metabolic imbalance of plamal protein and improve the living quality of the patients.
