[Experimental investigations on ultraweak photonemission form biological systems (author's transl)].
Measurements on untreated yeast cells, potato- and cucumber seedlings have confirmed the existence of photon emission from biological systems known as "ultraweak luminescence". The intensity is of the order of 10(2) counts per second, and the spectral distrubtion shows a maximum near 550 nm. The dependence of th photon emission on certain chemicals has been investigated. Some chemicals, as for instance acetone, intensify the photon emission from cucumber seedlings without essential change of the spectral distribution. On the other hand, NaCl leads to a shift to the red region of the spectrum. The treatment of EAT-cells by 4-Hydroperoxycyclofosfamide 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.
