  • Publication number: 20140235719
    Abstract: The present invention relates to the novel use (anti-inflammatory activity) of Ramalin isolated from the Antarctic lichen Ramalina terebrata, and more specifically to a pharmaceutical composition containing Ramalin as an active ingredient. Ramalin of the invention is a compound derived from natural material, has no toxicity or side effects, and inhibits the expression of inducible nitric oxide synthase (iNOS) in the transcription stage to significantly inhibit the production of nitric oxide (NO) that is a key mediator of inflammatory responses. In addition, it inhibits the activation of the inflammatory mediator NF-?B, inhibits p38 MAPK, ERK1/2 and JNK signaling pathways, and inhibits the expression of the LPS receptor TLR4, suggesting that Ramalin has an excellent anti-inflammatory effect. Thus, the composition containing Ramalin can be effectively used to fundamentally treat or prevent inflammatory diseases or immune diseases and to relieve or alleviate the symptoms of the diseases.

  • Patent number: 8035661
    Abstract: The driving apparatus of a display device calculates a slope using a minimum gray, a maximum gray, a gray average of frame data in a current frame, and a gray average of frame data in a previous frame, and corrects and outputs the input frame data according to the slope, using frame data of one frame. As a result, a gray range of the input image signal can be extended, thereby improving visibility. Further, in a case of a motion picture, even when a difference of a gray range of images of adjacent frames is large, an original image is not distorted due to extension of a gray range. Also, even when noise is included in the input image signal, a gray range can be extended after removing the noise.
