Clinical observation in 31 cases of chronic bronchitis at remission stage treated with bufei keli.

To observe the therapeutic effects of a Chinese drug Bufei Keli ([symbol: see text] granules for invigorating the lung) in the treatment of chronic bronchitis at remission stage, 62 cases were randomly divided into a treatment group (treated with Bufei Keli) and a control group (treated with Yupingfeng Keli [symbol: see text]). The results turned out to be that the short-term clinically controlled and markedly effective rate was 77.42% and the long-term relapse-resisting markedly effective rate was 74.2% in the treatment group, which were obviously higher than 45.16% and 38.71% respectively in the control group (P < 0.05). And the increase in contents of SOD and CD3 and the decrease in LPO content in the treatment group were also bigger than that in the control group (P < 0.01). It is therefore concluded that Bufei Keli can improve qi deficiency syndrome and raise the immunity of patients with chronic bronchitis, hence its effect of resisting relapse of chronic bronchitis.
