Abstract:
An experimental apparatus for a sliced specimen of a biological tissue used for performing physiological experiments holding a sliced specimen in a circulated saline solution and thereby maintaining physiological activities of the sliced specimen, comprising:an experimental vessel for holding saline solution; a specimen holder for holding the sliced specimen of the biological tissue, the specimen holder comprising a ring-shaped holder frame with a top and a bottom opening and a membrane filter closing the bottom opening of the holder frame when taken out of a cultivator and put in the experimental vessel; a specimen holder holding member for detachably holding the specimen holder in an interior space of the experimental vessel; a solution introduction tube for feeding fresh saline solution into the experimental vessel; and a solution discharge tube for sucking the saline solution from the experimental vessel; wherein the experimental vessel is comparatively shallow and open at a top portion thereof, wherein at least a part of a. bottom of the experimental vessel under the specimen holder mounted on the specimen holder holding member is transparent, wherein the specimen holder is held by the specimen holder holding member in the experimental vessel such that a desired spacing exits between the membrane filter and the bottom of the experimental vessel, and wherein the liquid level in the experimental vessel is adjusted by a height of the solution discharge tube, and the liquid level is kept constant at the height.
