Objective To detect the effect of chitosan gel on rectal injury which was induced by acetic acid. Methods 36 rats were anesthetized, 4% acetic acid swab was placed into the rectum (3 cm in depth for 1 min) to establish rectum injury model. These rats were divided into model control group, positive control group and drug group with 12 rats each group randomly. Chitosan gel was given to the drug group through anus with the dose of 1 575 mg·kg-1 , and hemorrhoid cream (1 575 mg·kg-1 ) was administered in the positive control group for 6 successive days. At 30 min, 1, 4, 6 day( s) after administration, 3 rats of each group were sacrificed, and were dissected, rectal injury and rectal pathology morphology changing of each group at different time points of administration were compared through visual observation. Results At 30 min, 1, 4, and 6 day(s) after administrating chitosan gel, score of rectum mucosa injury in dury group was lower than those in model control and positive control group. Pathological changes ( including epithelial tissue necrosis, mesenchyme hyperemia, hemorrhage, edema, gland injury, infiltration of inflammatory cells) were significantly slighter in drug group than in model control group and positive control group. Those lesions were restored faster in drug group than in model control group and positive control group, and there was no obvious scar. Conclusion Chitosan gel can obviously alleviate the rectal injury caused by 4% acetic acid and has therapeutic effect.

OBJECTIVE: To evaluate nasal ventilation in allergic rhinitis patients after nasal provocation with acoustic rhinometry. METHOD: Twenty AR cases were selected. Each one was assessed for the nasal cavity volumes (NCV), nasal airway resistance (NR), nasal minimal cross-section area (NMCA) and distance of nasal minimal cross-section area from nostril (DCAN) by using acoustic rhinometry before and after nasal provocation 1 hour and 6 hours later. The results were statistically analyzed. RESULT: After nasal provocation 1 hour 1 later, NCV and NR had a significant difference compared with before nasal provocation(P<0. 05), but NMCA and DCAN had no difference (P > 0.05). After 6 hours later, NCV, NR, NMCA and DCAN had a significant difference compared with before nasal provocation (P < 0.05). NCV,NR,DCAN had a significant difference between 1 hour later and 6 hours later after provocation (P < 0.05), while NMCA had no difference (P > 0.05). CONCLUSION The nasal ventilation in allergic rhinitis after nasal provocation had declined over time.
