[Clinical research on repeated infantile respiratory tract infection treated by fang-gan mixture].

131 cases of repeated infantile respiratory tract infection were selected and divided into 3 groups: fang-gan mixture (FGM) group, levamisole group, and the control group. The results showed that the total effective rate of FGM was 97.7%, which was more effective than the levamisole group. Its effective rate still reached 90.9% after 1 month of stopping treatment, and compared with the treatment period, there were no significant differences (P greater than 0.05). There were three parts of changes on clinical manifestation after patients using FGM: (1) The occurrence times reduced obviously; (2) the course of disease shortened obviously; (3) syndrome of patients relieved obviously. FGM was also more effective than the levamisole group in relieving symptoms and signs (P less than 0.05). Both the FGM and the levamisole groups could increase the body immunity function. After treatment both of salivary sIgA and PHA skin test were higher than before treatment (P less than 0.05).
