Abstract: This is a technology for non-contact power transmission to the laboratory animal biological information acquisition device 12 embedded in the multiple laboratory animals in the breeding cage 14, and provides the power reception device, which can observe the behavior of laboratory animals from outside without covering the breeding cage 14 with the power transmission side, and which can continuously supply power regardless of the direction and position of the laboratory animals. The secondary coil part 22 includes a magnetic core 31 having a circular cross-section perpendicular to the longitudinal direction, and a plurality of spiral coils 40a and 40b formed by winding a conductor so that the outer shape is substantially rectangular.

Abstract: The present invention aims at preventing or retarding a transition to hemodialysis treatment in kidney failure or decreasing the number of implementation of the hemodialysis therapy and preventing or lessening occurrence of accompanying hyperammonemia in hepatic insufficiency. To accomplish the purposes described above, the pathological improvement food of the invention is featured by being composed chiefly of indigestible polysaccharides and having restricted addition of protein components. Energy produced by exploiting the indigestible polysaccharides contributes to fungal protein synthesis using, as a N-source, urea or ammonia secretion into the intestine and excretion of proliferated bacteria with feces, so that nitrogen-containing low-molecular substances in the blood can be decreased, thereby to improve disorder of the kidney and liver.
