摘要：

We examined the dynamics of clot growth in vitro and found, that initially the clot grows at a constant speed, then abruptly stops and becomes surrounded by an "inhibition zone" in which coagulation is strongly suppressed. We also observed formation of "stratified structures" (target patterns) in which solid layers alternate with liquid blood. The experimental results strongly support a hypothesis that blood is a new type of excitable medium.
