Abstract: The present invention relates to a composition for preventing or treating transplantation rejection or a transplantation rejection disease, comprising a novel compound and a calcineurin inhibitor. A co-administration of the present invention 1) reduces the activity of pathogenic Th1 cells or Th17 cells, 2) increases the activity of Treg cells, 3) has an inhibitory effect against side effects, such as tissue damage, occurring in the sole administration thereof, 4) inhibits various pathogenic pathways, 5) inhibits the cell death of inflammatory cells, and 6) increases the activity of mitochondria, in an in vivo or in vitro allogenic model, a transplantation rejection disease model, a skin transplantation model, and a liver-transplanted patient, and thus inhibits transplantation rejection along with mitigating side effects possibly occurring in the administration of a conventional immunosuppressant alone.

Abstract: Disclosed are a mammography system and a mammography imaging method that can prevent a subject from being exposed to radiation more than necessary by setting an optimum imaging condition according to a thickness of a subject's breast, and can obtain a high-quality medical image by setting an optimum FOV and correcting projection data according to the thickness of the breast. The mammography system includes: a mammography imaging device including a detector and an X-ray tube, and obtaining X-ray image data of a subject's breast from multiple angles; a thickness obtaining unit obtaining information on a thickness of the breast; and a rotation angle calculator calculating a rotation angle range of the X-ray tube, based on the information of the thickness of the breast, wherein the mammography imaging device obtains the X-ray image data from multiple angles by performing radiography while rotating the X-ray tube within the rotation angle range.
