Abstract
Measurements on untreated yeast cells and potato and cucumber seedlings confirmed the existence of photon emission from biological systems known as ultraweak luminescence. The intensity is of the order of 102 counts/s, and the spectral distribution shows a maximum near 550 nm. The dependence of the photon emission on certain chemicals was investigated. Some chemicals, e.g., acetone, intensify the photon emission from cucumber seedlings without essential change of the spectral distribution. NaCl leads to a shift to the red region of the spectrum. The treatment of Ehrlich ascites tumor-cells by 4-hydroperoxycyclophosphamide involves a nonlinear enhancement of the intensity with increasing concentration. There are some indications that collective interactions of the system are more appropriate than simple chemiluminescence reactions.Keywords
