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-κB, 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-1β and TNF-α, 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.

The present invention relates to 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-α 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.

A fuel cell system is provided including a fuel cell stack and a starting controller. The fuel cell stack has output terminals for applying an output voltage. The starting controller is configured to control the output voltage applied across the output terminals of the fuel cell stack during a starting period to be a starting voltage lower than a rated voltage.
摘要:
A membrane electrode assembly in a fuel cell system includes a cathode electrode that includes a support layer; a catalyst layer; and a first carbon layer and second carbon layer between the support layer and the catalyst layer, the first carbon layer having a relatively higher porosity and the second carbon layer having a relatively lower porosity. Therefore, the membrane electrode assembly maintains good ion conductivity in the polymer electrolyte membrane by suppressing the movement of water molecules from the polymer electrolyte membrane to the cathode electrode using a water pressure between two carbon layers having different porosity. Also, a flooding phenomenon in the cathode electrode is prevented, thereby maintaining the smooth movement of the oxidizing agent in the cathode.
