Aims:
Explore the effect of compound lobelia oral liquid on acute pharyngitis rabbits model caused by ammonium hydroxide, evaluate its curative effect.
Methods:
Acute pharyngitis rabbit model was prepared by ammonia spray at pharyngeal. After 1 h of the last administration, score the pharyngeal tissue symptoms of rabbits under the condition of naked eyes (score according to the score criteria). Then, take blood from the marginal auricular vein for routine blood tests and serum TNF-α level measure. Take pharyngeal tissue for HE staining, and observe its pathological changes under the microscope.
Results:
Compared with the blank group, the pharyngeal tissue symptom score and serum TNF-α level in the model group were significantly increased (P < 0.01). The results of blood routine showed that the number of white blood cells and lymphocytes in the model group increased significantly (P < 0.01), and neutrophilic granulocyte percentage decreased significantly (P < 0.01). The infiltration of inflammatory cells in the pharynx tissue was obvious and pathological changes were observed. Compared with the model group, large, middle and small doses of compound lobelia oral liquid group could reduce the scores of pharyngeal tissue symptoms in rabbits with acute pharyngitis induced by ammonia. The large and middle dose compound lobelia oral liquid group could significantly reduce serum TNF-α level and neutrophilic granulocyte percentage, significantly increase the number of white blood cells and lymphocytes (P < 0.01); The small dose compound lobelia oral liquid group could significantly reduce the number of white blood cells and lymphocytes (P < 0.01), there was an increasing tendency to neutrophils and a decreasing tendency to serum TNF-α, but no statistical significance. The large, middle and small doses of compound lobelia oral liquid group all could improve the pathological changes of pharyngeal tissue inflammatory infiltration.
Conclusion:
Compound lobelia oral liquid has a good effect on rabbit acute pharyngitis model caused by ammonia.

01:30Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
01:23Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
