Abstract:
:Cells and organisms exposed to detrimental and toxic substances show different responses in photon emission dependent on amount, kind and exposure time of toxin as well as on the organism investigated. Radical reaction-generating substances and dehydrating, lipid dissolving and protein denaturating toxins which do not induce direct chemiluminescence resulting from reactive oxygen species were applied. Lethal doses of toxins and stress factors such as osmotics and temperature evoke increase in the intensity of photon emission resulting from a rapid and irreversible perturbation of homeostasis. Bacterial and fungal toxins that elicit hypersensitive death of plant cells or defense response correlated with photon emission are also briefly discussed. Collective molecular interactions contribute to the photon-generating degradative processes in stressed and dying organisms. The measurements of biophoton signals and analysis of their parameters are used to elucidate the possible mechanisms of the toxin-organism interaction and the resistance of organisms. Toxicological perspectives of the use of these sensitive and rapid measurements as a part of direct toxicity assessment are discussed.
