Abstract: Provided is a method for preventing and alleviating inflammatory bowel disease by administering a composition including puer tea extract as an active ingredient to a subject in need thereof. Puer tea extract of the present disclosure showed an effect of improving damaged colonic tissue in a mouse model of acute ulcerative colitis induced by dextran sulfate sodium (DSS), and showed an inhibitory effect on clinical symptoms of the disease activity index (DAT) of weight loss, diarrhea, and rectal bleeding. In addition, puer tea extract inhibited the expression of inflammatory cytokines TNF-? and IL-6 in the colonic tissue and inhibited the inflammatory response through inhibition of the activity of NF-?B, an anti-inflammatory mechanism. In addition, the DPPH free radical and ABTS free radical scavenging ability increased proportionally as the concentration of puer tea extract increased at the cellular level, and COX-2 expression was inhibited in LPS-activated macrophages.

Abstract: A portable slit lamp device which can be coupled to an image capture device such as a smartphone.

Abstract: A mouthpiece-type orthodontic device using ultrasonic vibration, in which: an ultrasonic vibrator is installed inside a mouthpiece, and ultrasonic waves emitted from the ultrasonic vibrator affect the movement of teeth requiring correction, thereby making it possible to shorten the correction time is proposed. A vibration attenuator is attached to the outside of the mouthpiece contacting the teeth that do not need to be moved, and thus the ultrasonic vibration can be selectively transmitted only to the teeth requiring correction. Further, a plurality of grooves are formed on the outside of the mouthpiece, and the vibration attenuator can be mounted thereto, thus making it possible to selectively transmit the ultrasonic vibrations only to the teeth requiring correction.

Abstract: A stomatitis treatment device which is equipped with a light emitting means inside a housing to enable inflammations on the roof of the mouth and the upper side of the tongue to be treated, and to which a coupling module is attached to allow inflammations occurring on the lower side of the bottom of the mouth, etc. to be treated, is proposed. The stomatitis treatment device allows the roof of the mouth, the tongue, and the bottom of the mouth to be simultaneously irradiated with light for treatment by attaching and detaching the coupling module to and from the housing having the cell regeneration lamp therein, and thus can be used by patients having severe stomatitis with multiple lesions.
