Abstract
Major symptoms of al1ergic rhinitis are nasal obstruction, sneezing and watery rhinorrhea. Onpyetang has been used to treat for nasal obstruction, which is one of the symptoms of allergic rhinitis. This Experimental study was done to research effects of Onpyetang and transformed Onpyetang(Allii Radix is deducted from Onpyetang) on the anti-allergic effects. We have studied the vascular permeability response induced by serotonin and histamine, the contact dermatitis response induced by picryl chloride, the delayed type hypersensitivity response to SRC, the mice paw edema induced by carrageenin, the writhing syndrome induced by $0.7\%$ acetic acid, and the rectal temperature in febrile rats induced by yeast. The results were as follows : 1. In the vascular permeability response to intradermal serotonin and histamine. Onpyetang proved significant inhibitory effect(P<0.05, p<0.001) But transformed Onpyetang proved significant inhibitory effect only to histamine(P<0.05) 2. In the contact dermatitis response induced by picryl chloride, Onpyetang and transformed Onpyetang proved significant inhibitory effect.(P<0.05, P<0.05) 3. In the delayed type hypersensitivity response induced by SRC, Onpyetang and transformed Onpyetang proved significant inhibitory effect on mice paw edema.. (P<0.05, P<0.05) 4. In the delayed type hypersensitivity response induced by SRC, Onpyetang proved significant inhibitory effect to serum IgE.(P<0.01) But transformed Onpyetang proved insignificant inhibitory effect on serum Ig E. 5. In the mice paw edema induced by carrageenin, Onpyetang and transformed Onpyetang proved significant anti-inflammatory effect. (P<0.01, P<0.01) 6. In the writhing syndrome induced $0.7\%$ acetic acid, Onpyetang and transformed Onpyetang proved significant analgestic effect. (P<0.01, P<0.01) 7. In the rectal temperature in febrile rats induced by yeast, Onpyetang and transformed Onpyetang proved significant anti-pyretic effect.(P<0.001, P<0.01) according to this result Onpyetang was conclude to be effective on anti-allergic, anti-pyretic, anti-inflammatory and analgestic action. but transformed Onpyetang(Allii Radix is deducted from Onpyetang) was not effective on the vascular permeability response to intradermal serotonin and increasing Ig E of delayed type hypersensitivity response induced by SRC. In addition, transformed Onpyetang is not effective as Onpyetang. More study should be done about the role of Allii Radix.
