    摘要： There is disclosed an apparatus for the determination of a trace amount of an analyte substance or organism. A substrate solution is brought into contact with a small diameter tube which has captured, at least on its inner surface, a trace amount of an analyte substance or organism. The trace amount has the ability to change the pH of the substrate solution. A pH change following a reaction of a substrate in the substrate solution in the small diameter tube is measured; the apparatus has a cuvette having an inlet and an outlet for the substrate solution, a pH electrode accomodated in the cuvette, a pump for supplying the substrate solution in the cuvette, a positioning structure for positioning, in the cuvette, the small diameter tube with the pH sensitive plane of the pH electrode and spacing the surface and the plane at 1 mm or below from each other, and a sealing structure for maintaining a formed by the outer surface of the small diameter tube accommodated in the cuvette and the inner surface of the cuvette at liquid tight condition.

    摘要： Provided is a cell culture method whereby an in vivo function can be sustained over a long period of time and culture can be conducted using the minimum number of cells required. The cell culture method includes culturing undifferentiated cells in a layered state in a partitioned micro-space and obtains differentiated cells. When screening a pharmaceutical agent, undifferentiated cells capable of differentiating into liver cells, intestinal epithelial cells, nerve cells, myocardial cells and vascular endothelial cells are preferred. Particularly, in the prediction of pharmacokinetics or the like for humans, human cells are preferred.

    摘要： To provide a cell culture method capable of sustaining in-vivo functions for a long time by suppressing dedifferentiation. A cell culture method in accordance with the present invention is to culture cells in a multi-layered state in a minute partitioned space and to obtain a tissue structure having a function resembling an in-vivo function. When the cells are mammary gland epithelial cells, a hollow acinus-like structure can be formed. The minute partitioned space is particularly preferably a micro container in a cell culture container having a plurality of such micro containers on the surface.

    摘要： A polyamide having an equilibrium water absorption of not more than 10% is used as a main material. As a polyamide having an equilibrium water absorption of not.more than 10%, for example, a polyamide comprising a dicarboxylic acid component comprising 60-100 mol % of terephthalic acid and a diamine component comprising 60-100 mol % of 1,9-nonanediamine and/or 2-methyl-1,8-octanediamine is used. As a result, a porous membrane showing extremely small dimensional change even after a hot water treatment, and particularly useful as a medical separation membrane permitting an AC sterilization treatment and the like is obtained.
