New Medical Use of e-cigarette Liquid Discovered by Russian Scientists
According to a report by RIA Novosti, scientists from Saratov State University in Russia have unexpectedly discovered alternative uses of e-cigarette liquid in the field of medicine.
According to them, the ingredients in e-liquid can enhance the transparency of tissues to light waves, allowing doctors to better observe affected organs and evenly irradiate them during the treatment process, such as in the treatment of mucous membranes in throat and lung cancer.
Optical tissue visualization is considered a promising direction in medical diagnostics. It allows for detailed examination of diseases, particularly the spread of cancer, and the study of cellular internal structures, explained Professor N.G. Chernyshevsky from Saratov State Research University.
In order to ensure the uniform and effective penetration of radiation through the skin and internal organs, a special transparent agent is required. This agent should have the ability to reduce the scattering of light in biological tissues without absorbing the wavelengths necessary for diagnosis. This is crucial for the successful detection of diseases.
Valery Tukhin, director of the Department of Optics and Photonics at Saratov National Research University and academician of the Russian Academy of Sciences, explained, "Our research proves that e-cigarette liquids are the optimal agents for various new biological diagnostics in the respiratory tract and oral cavity. These liquids, composed of vegetable glycerin and propylene glycol, have previously demonstrated high efficiency in transparent agents, and their combination proves to be most effective.
He further pointed out that glycerol is the unique active ingredient in this diagnosis because it does not absorb light over a very broad spectrum, ranging from infrared to ultraviolet with a minimum wavelength of approximately 150 nanometers. Propylene glycol, on the other hand, enhances the permeability of biofilms to glycerol.
Because the proportions of these two components differ in various mixtures, it is easy to select the optimal ratio for medical use. It is worth noting that the e-liquids being discussed by scientists do not contain nicotine or flavorings.
He continued, "These characteristics are not only necessary in diagnosis, but also in phototherapy treatment, such as treating cancer using laser irradiation or other sources of light waves, and significantly improving the photosensitivity of specific tissues. Glycerol propylene glycol mixture not only provides better target visualization, but also achieves more uniform light distribution in deep tissues. These advantages will help reduce radiation dosage and improve treatment effectiveness.
Scientists also added that e-cigarette liquid can be used as an antifreeze when freezing live organs - that is, by placing the organs in this mixture, they can be cooled to extremely low temperatures without forming sharp ice crystals that can damage cells.
However, prolonged exposure to e-cigarette vapors can potentially result in throat cancer, lung cancer, and cardiovascular diseases due to the effects on the oral and lung mucosa. In addition, e-cigarettes also increase vulnerability to viruses and toxins as propylene glycol can facilitate the penetration of various particles and molecules from the air into the bloodstream.
