Abstract: Disclosed is an image display system having a plurality of CRT display screens. The system is of the type in which a number of images of specific portions of a patient having a specific ID code are selected from among a multitude of X-ray image taken by a plurality of shooting methods, and when the regions of interest are specified, a plurality of appropriate images are further selected using the previously stored aptitude values for the regions and shooting methods and displayed on said plurality of CRT display screens. In order that the segments to be inspected can be pointed to on the screen on which the image of the patient is displayed, a memory is provided which is adapted to previously store codes corresponding to the specific image of the patient and to specify the respective regions of the image in such a manner that they correspond to the pixel positions of the image.

Abstract: Neuraminidase is produced by culturing a neuraminidase producing microorganism belonging to the genus Micromonospora. The neuraminidase is useful for the quantitative determination of a sialic acid-containing substance in a sample.

Abstract: The present invention provides a process for producing N-acetylneuraminate lyase using a microorganism constructed by recombinant DNA techniques.

Abstract: Glutathione peroxidase is produced by fermentation of a microorganism of the genus Mucor. This peroxidase may be used for the determination of lipid peroxide.

Abstract: A 3N-substituted 3,4-dihydropyrimidine derivative of the formula: ##STR1## wherein R.sup.1 is methyl or ethyl, R.sup.2 is methyl or ethyl, R is phenyl or substituted phenyl, X is chloro or methyl and pharmaceutically acceptable acid addition salts thereof have substantially the same strong vasodilative and Ca.sup.++ antagonistic effects as nicardipine and therefore are useful as agents for treating disorders of the cardiovascular system, for example, hypotensive agents, agents for amelioration of brain circulation and anti-angina pectoris agents.Processes for producing the above compounds economically and effectively are also disclosed.

Abstract: Galactose oxidase is produced by culturing a microorganism belonging to the genus Gibberella. The enzyme is useful in the determination of galactose.

Abstract: Glycerol oxidase is an oxidizing enzyme of glycerol characterized by its ability to oxidize glycerol in the presence of oxygen to form hydrogen peroxide and glyceraldehyde. This enzyme is produced by cultivation of a microorganism belonging to the genus Aspergillus or the genus Neurospora in a nutrient medium.
