Abstract (in Japanese) (See Japanese page) 
(in English) To predict drug safety variables, traditional cardiac testing for new drug has involved invasive examination using implanted electrode in small animals. But today, alternative non- invasive methods have been developed because of high quality data derived from nonsurgical treatment of many animals. The advantage of magnetocardiograph（MCG）is the non-invasive measurement of cardiac physiological study. Therefore, we have developed the HTS-SQUID system for non-invasively toxicological and safety study. Then we have estimated the sensitivity of HTS-SQUID system and measured mice MCG. As a result, the white noise level was measured as 8 μΦ0/√Hz using AC current bias. Moreover, we could detect mice MCG and its magnetic field was 25 pT(p-p). Therefore the non- invasive approach, as the mouse MCG measurement, could be carried out under low-noise condition using our SQUID system.
