Imaging of biophoton emission from electrostimulated skin acupuncture point jg4: effect of light enhancers.

Using an ultrasensitive CCD camera, an extremely low light intensity from the acupuncture-sensitive point JG4 at the left hand was recorded. As the intensity of the light was very weak and the time of electrostimulation exceeded the recommended period, the quality of biophoton images was poor. Chemiluminescent and fluorescent hydrophilic, hydrophobic and amphyphilic molecular probes were used to: (i) ensure penetration of probes into skin, (ii) enhance the intensity of BP emission, (iii) shorten time and (iv) obtain information about mechanisms of biophotons generation in EAP-sensitive points and channels.

Photon emission from perturbed and dying organisms: biomedical perspectives.

Living systems spontaneously emit ultraweak light (ultraweak photon emission, UPE) during the process of metabolic reactions associated with the normal physiological state. Stress factors and pathological states change parameters of that emission, such as intensity, yield, temporal, statistical and spectral characteristics. Thus, properties of UPE are inherently associated with and derived from biochemical and biophysical excitation processes.

Biophotons from stressed and dying organisms: toxicological aspects.

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.

Secondary Ultraweak Luminescence from Humic Acids Induced by gamma-Radiation.

Humic substances (HSs) are products of biochemical transformations of plant and animal residues that make up a major fraction of the organic carbon of soil and aquatic systems in the environment. Because radioisotopes occur in the Earth's crust and because the entire biosphere is continuously exposed to cosmic radiation, ionizing radiation continually interacts with HSs. This chronic irradiation could have a significant ecological impact.

Model studies of zinc bonding with humic acid in the presence of UV-VIS-NIR radiation.

Model experiments were performed to determine the influence of UV-VIS-NIR radiation on zinc bonded with humic acid (HA). The samples of HA or HA-65Zn radioisotope were overlayed on quartz sand in a glass column and subjected to elution that simulated natural conditions. The zinc concentration was chosen to that occurring in the sewage of the Central Sewage Work in Poznań.
