Abstract: A laser scanning unit scans a light beam onto a photoconductor to form a latent image. The laser scanning unit includes a light source that generates and radiates a light. A polygon mirror deflects and scans the light emitted from the light source. A driving motor drives and rotates the polygon mirror. A circuit substrate has a first surface on which the polygon mirror and the driving motor are coaxially mounted. A housing, to which the circuit substrate is coupled, includes an opening through which the polygon mirror is introduced in the inner space. A second surface of the circuit substrate to the opposite side of the polygon mirror is entirely exposed to the outside to function as a heat radiation surface. Thus, the heat dissipation characteristic of heating dissipation components, including a driving motor, is improved and the inner sealing of the laser scanning unit is secured.

Abstract: Compounds of Formula I potently inhibit both cyclooxygenase-2 and carbonic anhydrases. Inhibition of carbonic anhydrases by a cyclooxygenase-2 inhibitor may affect significantly the safety and efficacy profiles of such a dual inhibitor in the treatment of cyclooxygenase-2 mediated disorders, compared to a cyclooxygenase-2 inhibitor without carbonic anhydrase inhibitory activity.

Abstract: The present invention relates to novel thiourca derivatives as a modulator for vanilloid receptor (VR) and the phar- maceutical compositions containing the same. As diseases associated with the activity of vanilloid receptor, pain acute pain, chronic pain, neuropathic pain, post-operative pain, migraine, arthralgia, neuropathies, nerve injury, diabetic neuropathy, neurodegeneration, neurotic skin disorder, stroke, urinary bladder hypersensitiveness, irritable bowel syndrome, a respiratory disorder such as asthma or chronic obstructive pulmonary disease, irritation of skin, eye or mucous membrane, fervescence, stomach-duodenal ulcer, inflam- matory bowel disease and inflammatory diseases can be enumerated. The present invention provides a pharmaceutical composition for prevention or treatment of these diseases.

Abstract: The present invention provides a novel class of 4,5-diaryl-3(2H)-furanone derivatives, which inhibit strongly and selectively COX-2 over COX-1. They are useful to treat inflammation, inflammation-associated disorders, and COX-2 mediated diseases.

Abstract: The diarylbenzopyran derivatives represented by formula I, and the pharmaceutically acceptable salts thereof, are disclosed. The composition comprising the compound of formula I, or a pharmaceutically acceptable salt thereof, shows an excellent selective inhibition of cyclooxygenase-2.
