title: [The rationale for the application of laserophoresis of biologically active compounds].
abstract: Laserophoresis is a technique for the transcutaneous administration of biologically active compounds by means of low-intensity laser radiation (LFLR). It is currently regarded as a most promising method for the integrated application of a pharmaceutical substance and a physical factor. At present laserophoresis of various medicinal preparations is successfully used after preliminary experimental studies of their phoretic properties for the treatment of various inflammatory and dystrophic conditions as well as for the prevention of skin ageing. The most important route for the administration of the majority of drug preparations is through the shunts provided by perspiratory glands and hair follicles. Another essential factor determining the potential possibility of drug penetration through the skin is the characteristic of the substance chosen for the administration, such as its molecular weight, chemical structure, conformation, and hydrophilic properties. However, the most likely mechanism underlying the transport of the substance through the glandular cells of perspiratory glands and epithelial cells of hair follicles is pinocytosis, i.e. the process integrating exocytosis and endocytosis. To-day, the majority of the researchers lay emphasis on thermodynamic triggering of Ca2+-dependent processes as the primary mechanism behind the biological action of low-intensity laser radiation. Both exocytosis and endocytosis being the Ca2+-dependent processes, the liberation of Ca2+-ions under the influence of LFLR causes the activation of pinocytosis as a whole.
