摘要:
By using the input unit, a condition previously regarded necessary, for example, some parameter values of a plurality of frequencies are registered as a group. The registered parameter values are stored in a memory within the apparatus setting condition controlling unit. An operator selects a desired group at a diagnosis time, and selects a parameter value to be used for diagnosis, from a plurality of parameter values forming the group. The apparatus operates based on the operational condition defined by the parameter value, to make a diagnosis.
摘要:
Novel tripeptide derivatives having a pyroglutamic acid residue strongly inhibit a plurality of trypsin-like serine proteases such as plasmin, thrombin, trypsin, kallikrein, factor Xa and urokinase. The compounds of the present invention can inhibit various trypsin-like serine proteases and are expected to show remarkable effects as novel protease inhibitors for the treatment of pancreatitis, inflammantion, ulcer, etc.

An ultrasonic diagnostic apparatus includes an memory, an determination unit, an instruction unit, a specifying unit, and an redetermination unit. The memory stores upper limit values of parameters for restricting the powers in display modes. The determination unit determines the powers in the modes so as not to exceed upper limit values of the parameters. The instruction unit inputs an instruction to increase/decrease the power of a specific mode. The specifying unit specifies the parameter value in the specific mode. The redetermination unit determines an upper limit value of the parameter in a mode different from the specific mode based on the upper limit value of the parameter in the specific mode and the parameter value specified by the specifying unit.

摘要:
An ultrasound image diagnosis apparatus and a method for setting an ultrasound drive voltage by which appropriate probe motion parameters are established by individually estimating temperature changes which occur due to a plurality of heat sources existing within the probe. By individually storing or correcting relative temperature change data associated with motion parameters due to a plurality of heat source elements, an optimum driving voltage for the ultrasound transducers is set. Since a transmission drive voltage is larger than the conventional drive voltage can be set under a permissible probe temperature, image diagnosis can be improved.

Novel N.sup.G -protected or unprotected-L-argininal-dibutyl acetals (I) can be prepared from L-argininal derivatives (III) merely by reacting in an azeotropic solvent in the presence of p-toluenesulfonic acid. In the products (I), L-form amounts to more than 99%, without further optical resolution. The L-argininal acetals (I) are useful as starting materials for preparing peptidyl-L-argininal derivatives which can provide protease inhibitors or ligands used for affinity chromatography of various proteases.

According to one embodiment, a gain adjustment unit executes gain adjustment for 3D B-mode data using gain adjustment values respectively decided for the depth on each scanning line, azimuth direction and elevation direction in a scanned region. A threshold decision unit decides a threshold used for discriminating lumen and non-lumen regions in the scanned region using the gain-adjustment-executed 3D B-mode data. A threshold processing unit executes threshold processing to discriminate data concerning the non-lumen region from the gain-adjustment-executed 3D B-mode data, using the threshold. An image generation unit generates an ultrasonic image concerning the lumen region based on the threshold-processing-executed 3D B-mode data.
