Abstract: A novel optical-isomer separating agent for chromatography is provided which has, as a chiral selector, a macrocyclic amide compound having the ability to function as a chiral shift agent. The optical-isomer separating agent for chromatography is formed by bonding, with a carrier by chemical bonding, a specific ring structure containing an asymmetry recognition site, an amide group as a hydrogen-bond donor site, and a hydrogen-bond acceptor site.

Abstract: An object of the present invention is to provide a living body measuring device which, once the personal information having been set therein, executes an arithmetic operation simply by making a measurement without requiring a user to remember his/her personal memory number. The living body measuring device of the present invention stores the measured body weight value and/or bioelectrical impedance value as well as the personal body information set in the initial stage, compares the measured values with those stored values, and determines a current subject who is being measured by considering the most proximal values to be the data associated with the measured subject, thereby calculating a body-related index automatically. Especially, if both of the bioelectrical impedance and the body weight are used, then the determination may be more accurate.

Abstract: Disclosed is an improvement in a living body variable measuring device comprising: a power supply; an inputting unit for inputting physical data of individuals whose body variables are to be measured; a memory device for storing the physical data of individuals thus inputted; a bioelectrical impedance gauge; an arithmetic operation-and-control unit for determining the living condition of each individual from the bioelectrical impedance and the personal physical data; and a display for displaying the result of the arithmetic operation and other pieces of information. It further comprises a lid for covering the body of said measuring device. The lid is equipped with a switch responsive to the opening of the lid for turning said power supply on.
