Effect of Sodium Cromoglycate on Acetic Acid-induced Ulcerative Colitis in Mice / 대한소화기학회지

BACKGROUND/AIMS: Ulcerative colitis (UC) is a type of inflammatory bowel disease that mainly involves the colon. Thus far, glucocorticoids and amino-salicylate have been the main treatment.METHODS: To assess drugs with fewer side effects, this study evaluated the effects of sodium cromoglycate (SCG) on acetic acid-induced UC in rats. The treatment groups included SCG receivers (50 and 100 mg/kg, intra-orally) and sulfasalazine (SSZ) receivers (100 mg/kg, intra-orally). The colonic mucosal injury was assessed by clinical, macroscopic, and histopathological examinations.RESULTS: In the treatment groups with 50 and 100 mg/kg of SCG, the clinical activity score decreased to 2.67±0.18 and 1.73±0.21 (p<0.05), respectively, compared to the UC control group (3.21±0.31), and were higher than that of the group given the standard treatment of 100 mg/kg SSZ (1.10±0.09). The treatment groups with 50 and 100 mg/kg of SCG showed a lower clinical gross lesion score than the UC control group (2.91±0.28 and 2.10±0.43, vs. 4.49±0.61, p<0.05) and were higher than the standard group (0.95±0.18). Treatment with SCG (100 mg/kg) decreased the macroscopic scores significantly compared to the UC control group (p<0.05) on the 8th day.CONCLUSIONS: SCG (100mg/kg) decreased significantly the clinical activity score, gross lesion, and percentage-affected area compared to the UC controls on the 8th day.

Wound healing potential of Althaea officinalis flower mucilage in rabbit full thickness wounds

Objective: To evaluate and practically demonstrate the influence of Althaea officinalis flower mucilage as a plant known in Iran's and other Middle Eastern countries' traditional medicine for its wound healing properties. Methods: Animals were divided into 6 groups of 5 cases including a non-treated group as the negative control group receiving no treatment, a group treated with eucerin as the positive control group, a phenytoin 1% group as a standard group treated topically with phenytoin 1% hand-made ointment, and treatment groups treated with hand-made Althaea officinalis flower mucilage (AFM) ointment in a eucerin base with different concentrations (5%, 10%, 15%). Results: Among the treatment groups, the AFM 15% ointment showed the best result. Wound healing duration was reduced by the surface application of these groups. Wound closure was completed on Days 14 and 15 in the AFM 15% ointment and phenytoin 1% groups, respectively. No significant difference was observed in healing period between these groups. Conclusions: In conclusion, AFM 15% ointment was found to reduce wound healing time without any significant difference with the phenytoin 1% ointment. The authors suggest increased AFM effectiveness in when combined with phenytoin or other effectual plants.
