STUDIES ON PHOTON EMISSION FROM Pyrocistis elegans INDUCED BY ELECTRIC STIMULATION
海洋甲藻Pyrocistis　elegans电激发光的研究

Cultured Pyrocistis elegans (P. elegans) were used as a model to study the effect of external electrical field on photon emission from cells. The results show that the behavior of photon emission from P. elegan induced by electric stimulation (electrically stimulated photo emission,ESPE) depends upon the cells, and the ESPE displays "delayed luminescence", its relaxation does not follow an exponential law, but shows a hyperbolic behavior. Some discussions are made on coherence of photon emission from the Cell population and on the difference of the effects of external fields on living system and on non-living systems. From point of view of physics, both have energy relationship, but the former is more informational that may open a new approach to study cell to environment and cell to cell communication.
