Title: Method for analyzing remnant lipoprotein
Inventor: KITAMURA TAKASHI
IPC: G01N33/92
Filed: 1994-09-09
Abstract: PURPOSE: To rapidly inspect the remnant lipoprotein in a sample by separating chylomicron and ultra-low specific gravity lipoprotein in serum sample by liquid chromatography and analyzing the amount of cholesterol of the both. CONSTITUTION: Chylomicron(CM) and ultra-low specific gravity lipoprotein(VLDL) in serum sample are separated by liquid chromatography. The sum of the amount of cholesterol of CM and that of VLDL is highly correlated to the total amount of cholesterol of remnant lipoprotein(RLP) which is measured by the immunity adsorption method. Thus, the amount of cholesterol of RLP in serum can be determined from the sum of the cholesterol of the separated CM and VLDL. The RLP itself cannot be directly separated by liquid chromatography but can be analyzed rapidly and indirectly.

Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To obtain a picture processing system capable of proper image processing even in a case that the number of channels required for synchronize- transferring image data can not be secured by changing at least one operation mode of plural image processors according to an acquired channel. SOLUTION: A control part acquires a necessary number of channels where data transferring period such as a synchronize-transferring mode is ensured on a high-speed serial communication I/F by a high-speed serial communication part (S113). Whether or not the channel aquiring processing is successful is judged (S114). The control part judges whether the operation mode of an image forming device can be changed or not (S118). When the operation mode can not be changed, a display part gives a prescribed warning (S120). When the operation mode can be changed on the other hand, the operation mode of the image forming device is changed (S119). Namely, the operation mode is changed to reduce the transferring speed of image data in a case that the number of aquired channels in small.
