Patent number: 8883226Abstract: A pharmaceutical composition for the prevention and treatment of inflammatory disease or asthma comprising the extract of Decaspermum fruticosum as an active ingredient. The extract of Decaspermum fruticosum of the present invention inhibited the increase of eosinophils in bronchoalveolar lavage fluid of the ovalbumin induced asthma animal model, had the activity of inhibiting the secretions of immunoglobulin and chemokine (Eotaxin) in bronchoalveolar lavage fluid and blood, and inhibited the secretions of NO and TNF-? in macrophages. Therefore, the extract of Decaspermum fruticosum of the present invention can be effectively used as an active ingredient of a pharmaceutical composition for the prevention and treatment of inflammatory disease or asthma, and of a health functional food for the prevention and improvement of inflammatory disease or asthma.Type: GrantFiled: February 7, 2012Date of Patent: November 11, 2014Assignee: Korea Institute of Oriental MedicineInventors: Sei Ryang Oh, Kyung Seop Ahn, Ok-Kyoung Kwon, Hyeong Kyu Lee, Joongku Lee, Hyouk Joung, Mee-Young Lee, Hwa-Young Son, Kyoung-youl Lee, Sang Woo Lee, Hang Jin, Wan Yi Li

Patent number: 8722110Abstract: Disclosed is a pharmaceutical composition for the prophylaxis and therapy of inflammatory diseases, allergic diseases, or asthma, comprising a velvet apple (Diospyros blancoi A. DC.) extract as an active ingredient. Having the inhibitory activity against the nuclear translocation of NF-?B, whose level is rapidly elevated in response to inflammatory stimuli, the velvet apple extract can suppress the production of NO and PGE2, the expression of iNOS and COX-2, and the release of IL-1? and TNF-?, and can significantly down regulate Th2-mediated IL-4 and IL-13 production. In addition, the extract was found to inhibit the activation of eosinophils in bronchoalveolar lavage fluid, and to suppress the secretion of immunoglobulins and chemokines in bronchoalveolar lavage fluid and blood, as measured by in vivo tests on an ovalbumin-induced asthma mouse model. Therefore, the extract can be used in the method for preventing or treating various inflammatory disorders, allergic diseases, or asthma.Type: GrantFiled: August 30, 2011Date of Patent: May 13, 2014Assignee: Korea Research Institute of Bioscience and BiotechnologyInventors: Kyung Seop Ahn, Ok-Kyoung Kwon, Sei Ryang Oh, Jung Hee Kim, Hyeong Kyu Lee, Mee-Young Lee, Hwa-Young Son, Kyoung-Youl Lee, Soo Yong Kim, Giselle Tomayo-Castillo, Katia Rosales-Ovares, Rodrigo Gamez-Lobo
