抄録

It is inevitable to examine drug effects on electrical activities as well as mechanical functions of human heart during drug development. Generally, drug assessments in human can only be executed at a late stage of drug development, and we predict drug effects on human by extrapolating data from animal experiments. In this process, a mathematical model of human cardiac cell, which enables us to conduct virtual experiments using computer, will be a useful tool. So far, several types of human cardiac cell models are available for membrane excitation, and only one Excitation-Contraction (E-C) coupling model was published by Sachse et al (2003). Therefore, we started developing a comprehensive model of human cardiac cell. We developed a human models of fast Na, L-type Ca, transient outward, delayed rectifier K currents and a contraction model based on the experimental data from intact human cardiac myocytes, although which was limited in comparison with animal data. Then, we incorporated the human models into a comprehensive cell model of guinea-pig heart, the Kyoto model (Takeuchi et al., 2006) to compose a cell model of human heart. We succeeded in construction of the human cardiac cell model which well reproduces E-C coupling. This novel human cardiac cell model will illustrate how we can extrapolate data from animal experiments to human response. [J Physiol Sci. 2007;57 Suppl:S202]
