All of these effects are based on objective studies that have been validated and verified.
• quickening of microcirculation
• increase of intracellular activity of many enzymes, particularly in Krebs cycle
• increased oxygen circulation, improved glucose utilization
• DNA synthesis stimulation (via phytohemaglutinin stimulation)
• increased fibroblast activity (as far as keloids are concerned activated fibroblasts are able to perform a re-
absorption of fibrin)
• phagocytosis activation
• activation of the Na/K pump on the membrane
• activation of metabolic processes in the cellula: partly through the Na/K pump and Ca transport affection, partly
through a direct activation of the mitochondrial system
• local level changes of important mediators -- inflammatory (histamin substances, prostaglandins) or e.g.,
endorphins.
When performing an in vitro experiment, no difference can be seen between laser beams applied in continuous and
pulse modes. However, when performing an in vivo experiment, we observe marked differences between a
continuous beam and a beam adjusted to a certain defined mode. In physical therapy, this phenomenon can be
observed when performing electrotherapy or applying ultrasound. It seems that, as far as a complex organism with its
numerous information systems and feedbacks is concerned, a physical quantity modulated to a certain frequency
features one additional quality -- specific information transmitted by this frequency.
The effect of laser beam in acupuncture is totally specific. A laser beam affects tissue in a way fully comparable with
the effect of an inserted needle -- but without any pain or complications related to needle introduction. The skin above
the acupuncture point is a light conductor for the laser beam. We find it interesting that in laser acupuncture, in
contrast with other forms of laser therapy, the wavelength of a laser beam is not of a big importance (however, red
lasers are slightly more effective) and the output of the device is of no importance at all (we can even use a pen-
laser). We conclude that, as far as this method of application is concerned, it is not the effect of a physical quantity
itself, but the above-mentioned transmission of information that plays the push button role.
Many treatments include several effects of laser light at a time (e.g., treatment of crural ulcer combine analgesic,
stimulative, as well as bactericidal effects).
4.6 Contradictions of non-invasive laser therapy
• direct irradiation of glands with intrinsic secretion
• direct irradiation of the eye. Irreversible changes of retina may occur.
• direct irradiation of malignities and potential pre-cancerous sites
• febrile patients
• use of pulse modes or infra-red lenses on patients with seizure diseases such as epilepsy
• application to the abdomen area during gravidity
• patients with cochlear implants
