Abstract: A method and apparatus are provided for reconstructing 3D image. The method may include the steps of: detecting a plurality of line of responses (LORs) emitted from an object; transforming the plurality of LORs into first sinogram data; back-projecting the first sinogram data with a plurality of projection angles to produce image data for the object; and projecting the produced image data with the plurality of projection angles to transform the image data into second sinogram data. The back-projecting may include filling pixels of image plane for each of the plurality of projection angles with the first sinogram data and rotating a coordinate axis of the image plane with corresponding projection angle to produce the image data. The projecting may include rotating the image data with corresponding projection angle in an opposite direction before projecting the image data with the plurality of projection angles. The projecting and the back-projecting may use symmetry properties in coordinate space.

Abstract: The present invention relates to microorganisms for the treatment or the prevention of obesity or diabetes mellitus, which reduce the amount of monosaccharide or disaccharide which may be absorbed into human body by converting monosaccharides such as glucose, fructose, galactose et al. and disaccharides into polymeric materials which cannot be absorbed by the intestine, and relates to a pharmaceutical composition containing the said microorganisms.

Abstract: The disclosure concerns an extract of Acanthopanax koreanum and its use. More particularly, it concerns the extract of Acanthopanax koreanum comprising 1) the extract of Acanthopanax koreanum extracted from water, 2) among the water extract, the extract of Acanthopanax koreanum only containing ethanol insoluble part obtained by precipitating ethanol, 3) among the ethanol insoluble part, the extract of Acanthopanax koreanum containing polysaccaride with a molecular weight larger than range of 12,000˜14,000, or 4) among the ethanol insoluble part, the extract of Acanthopanax koreanum containing polysaccaride with a molecular weight larger than 100,000, which is respectively obtained from the root or stem of Acanthopanax koreanum. The extract of the present invention shows a high inhibitory activity against hepatitis and protects the liver, and thus, can be used for the treatment or prevention of hepatitis, or as a liver protective drug.
