  • Patent number: 8734866
    Abstract: The present invention relates to a composition for treatment and prevention of cardiovascular diseases, containing an extract of Lindera obtusiloba. More particularly, the extract of Lindera obtusiloba strongly inhibits NAD(P)H oxidases, which are the main cause of vascular diseases, and at the same time, regulates contraction and relaxation of vascular smooth muscles to manifest a potent vasorelaxant effect, thereby improving the blood pressure regulation and vascular endothelial dysfunction. Therefore, a composition containing this as an active ingredient can be usefully utilized as a pharmaceutical product or health functional food product for the prevention and treatment of cardiovascular diseases.

  • Patent number: 7394041
    Abstract: Disclosed is a waste gas treatment apparatus having a waste gas inlet for flowing a waste gas into a main combustion chamber provided in empty space inside a body, and a plasma torch configured to propagate flames against the waste gas flowing through the waste gas inlet. The apparatus comprises a steam injection nozzle configured to eject high temperature steam against the flames emitted through a nozzle of the plasma torch, and a reaction tube, extended longitudinally toward the bottom of the main combustion chamber into a tube shape, configured to perform the chemical reaction between a reaction accelerating compound and the waste gas induced by pressure of the nozzle of the plasma torch.
