Abstract: [PROBLEMS] Relating to a bioassay method with the use of cultured cells and cell culture for a therapeutic purpose in the case of determining the efficacy of a drug or the like or examining the toxicity thereof, it is intended to provide a method of culturing cells under regulation in the extension direction and a cell culture plate. [MEANS FOR SOLVING PROBLEMS] A cell culture plate having a plural number of side walls (1) and a plural number of space structures (3) for providing cultured cells which are formed by the side walls (1), wherein the side walls (1) are provided with openings (2) so that the space structures (3) are linked together. By using this cell culture plate, a method of culturing cells under regulation in the extension direction can be provided.

Abstract: A method for measuring hemodynamics of an experimental animal enabling repeated measurements, the method comprising the following steps: (i) ligating at least two parts of an artery, between which a part to be incised is located, of the experimental animal, the parts comprising at least one proximal ligated part and at least one distal ligated part, and then incising a part between the ligated parts; (ii) inserting through the incised part a blood pressure-volume simultaneously measuring catheter provided with multiple conductance electrodes and at least one pressure sensor; (iii) loosening the distal ligated part so as to allow an insertion of the catheter and not to cause bleeding in the opened part; (iv) further inserting the catheter so as to introduce the multiple conductance electrodes and the pressure sensor(s) into the heart ventricle; and (v) simultaneously measuring pressure and volume of the heart.
