Abstract: Objective:To investigate the therapeutic effects and mechanisms of Bianyanning on acute pharyngitis in rats, and to provide evidence and experimental data for its clinical application. Methods: The acute pharyngitis of rats was induced by spraying ammonia directly to their throat. The model rats were randomly divided into model control group, the high-, medium- and low-dose group of Bianyanning, while normal rats were used as control group, 10 in each group. After the corresponding drug treatment, the symptoms and manifestations of each group were observed and recorded; 24 hours after last gavaging, blood samples of each group were collected from the abdominal aorta. The serum contents of interleukin 1-beta (IL-1β) and tumor necrosis factor alpha (TNF-α) were detected by ELISA. HE method was used to observe the characteristic of the lung tissues and the transmission electron microscopy method was used to observe the trachea cilia. Results: After the treatment, compared with the model control group, the high-, medium- and low-dose group of Bianyanning, the symptoms of acute pharyngitis such as inflamed and congestive throat were relieved obviously. The morphological changes of lung and bronchus tissues were apparently improved. The contents of IL-1β and TNF-α in serum were decreased significantly. Conclusion: Compound Bianyanning can promote the recovering process of acute pharyngitis, improve the morphology of lungs and bronchus, which may be related to inhibiting the releasing of the IL-1β and TNF-α in serum.

Key words: Bianyanning, acute pharyngitis, lung tissue, lung bronchus, IL-1β, TNF-α
