The time pattern of selenomethionine administration in preventing free radicals due to exposure to electric cigarette smoke

Background: Most people believe that electric cigarettes have no negative effect on health, which causes them to use it more. However, exposure to the smoke from these cigarettes is bad for the health and causes cell damage. Antioxidants play an important role in preventing cell damage, and they can be obtained through the oral administration of selenomethionine. Design and methods: This study used an experimental method and a post-test control group design. Male Wistar rats, which were exposed to cigarette smoke were given selenomethionine orally and then tested for the presence of free radicals. The measurement of lung tissue damage was conducted by assessing the level of malondialdehyde in the blood and immunohistochemistry (IHC) of the lung tissue. Result: The study showed that differences in the time of administration of selenomethionine affect the levels of malondialdehyde in the blood and expression of malondialdehyde in the lung tissue (p<0.05). Consequently, the two groups showed a strong (r=0.861) and significant (p=0.000) relationship with each other. Conclusion: The early application of selenomethionine can prevent increased levels of malondialdehyde in the blood and lung tissue due to exposure to e-cigarette smoke.
