OBJECTIVE: To study the clinical effect and mechanism of Eryanling (EYL) oral liquid in treating acute catarrhal otitis media (ACOM). METHODS: Sixty-eight cases (89 ears) of ACOM in the treated group were treated with EYL and compared with 34 cases (44 ears) in the control group treated with cephalexinum. Experimental study of effect of EYL on immune function in mice and non-suppurative otitis guinea pig was also conducted. RESULTS: The total effective rate of the treated group and the control group was 91.0% and 84.1% respectively, and their rate of curing 80.9% and 70.5% respectively, though the effect in the former was better, statistic analysis showed no significance between them. The effect initiated obviously earlier in the treated group than that in the control group. Results of experimental study suggested that EYL could strengthen the nonspecific immune function, cellular immune function and humoral immune function in mice, and reduce the degree of inflammatory exudation and mucosa swollen in guinea pig. CONCLUSION: EYL has good therapeutic effect in treating ACOM.
