Abstract: There is provided a method for noninvasively evaluating the cell state (proliferation, multi-layering, and differentiation) of a cell sheet as a mimic tissue at the time of culturing the cell sheet. The method is characterized in that an analysis of an amino acid is conducted with the use of the culture supernatant of a cell sheet to monitor a change in the concentration of any amino acid selected from a group of 5-species of amino acids (Ile, Val, Ser, Leu, and Ala), thereby making a determination.
Abstract translation: 提供了在培养细胞片时非侵入性地评估作为模拟组织的细胞片的细胞状态（增殖，多层和分化）的方法。 该方法的特征在于，使用细胞片的培养上清液进行氨基酸的分析，以监测选自5-种氨基酸的组中的任何氨基酸的浓度变化（Ile， Val，Ser，Leu和Ala），从而进行测定。

Abstract: The automatic analyzer includes: a member to be washed, such as a probe or a stirrer for contacting and stirring a liquid; a wash station in which the member to be washed is washed with a washing liquid; and a measuring part that measures an optical characteristic of an evaluation reagent contained in a reaction cell. A control unit brings the member to be washed that has been washed in the wash station into contact with the evaluation reagent, causes the measuring part to measure the optical characteristic after contact with the evaluation reagent, and calculates the amount of the washing liquid carried into the reaction cell by the member to be washed, based on the measured optical characteristic.

Abstract: The automatic analyzer includes: a liquid dispensing mechanism that performs suction of a liquid; a pressure sensor that measures a change of an internal pressure of a probe provided at the liquid dispensing mechanism; a determination section that determines whether the suction of the liquid by the probe is normal suction or air suction abnormality; an analysis section; a storage section that stores a cumulative number of times of air suction abnormality per liquid and an allowable cumulative number for the cumulative number of times of air suction abnormality; and a controller that exercises operation control over the liquid dispensing mechanism, the determination section, and the analysis section. The controller exercises control such that the cumulative number of times of air suction abnormality is updated and the updated cumulative number is stored in the storage section even if the air suction abnormality occurs non-consecutively.

Abstract: The purpose of the present invention is to provide an automatic analysis device capable of determining, through a simple processing, whether or not idle aspirate has occurred. The automatic analysis device according to the present invention determines whether or not idle aspirate has occurred, by calculating a parameter which specifies whether or not the length of a portion of a path through which the sample passes inside a dispensing probe is shorter than that during normal aspirate, the portion being actually filled with a sample (see FIG. 4).
