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.

This study was aimed to investigate the hemostatic effects of hemocoagulase agkistrodon (HCA) and its mechanism. The procoagulative and hemostatic effects of HCA were evaluated by using rabbit blood coagulatin time and mouse tail bleeding time; the mechanisms of HCA hemostatic effect were analyzed by using rabbit blood clot lysis and fibrinogen lysis. The results showed that HCA shortened the rabbit blood coagulation time and the mouse tail bleeding time significantly. The effects are nearly similar to that of positive control (reptilase). HCA also induced rabbit blood clot lysis and directly hydrolysed the alpha-chain of fibrinogen. It is concluded that HCA exert its hemostatic effects by hydrolysing the alpha-chain of fibrinogen, but it is not able to induce production of XIII factor.

0.05).Overall prevalence of UI was 15.93% in the students,20.45% in those of junior high school,10.44% in senior high school and 16.72% in university(P0.05),accounting for 63.90%,10.47% and 25.63% of the total students with UI.Conclusions Great importance should be attached to the higher prevalence of LUTS in young and adolescent females by gynecologists and urologists.More attention should also be paid to health education on LUTS and medical care for those with LUTS to alleviate and delay occurrence of UI symptoms.
