Objectives: The negative health effects of electronic cigarettes remain debatable. Several studies have shown the adverse effects, but there are others who opine that electronic cigarettes are safer to use than the tobacco counterparts. There is however, a possibility that the long-term health effects, such as respiratory and even kidney function impairment are presently not obvious. The amounts of increased free radicals and pro-inflammatory cytokines from e-cigarettes result in various physiological disorders, which trigger cell damage, and even cell death in the body. Methods: The aim of this study is to analyze the stages of lung tissue damage caused by exposure to electronic cigarette smoke. An experimental method was used herein with a control and a experiment group of male wistar rats to assess the levels of malondialdehyde, interleukin-8, interleukin-10, matrix metalloprotein-8, and collagen type 2. The results were obtained using immunohistochemical staining methods on alveolar macrophages through Hematoxylin-Eosin (H & E) staining. Results: The results showed that exposure to electronic cigarette smoke caused an increase in free radicals, triggered an inflammatory process, and degraded the type 2 collagen present in the lung tissue. Conclusion: Exposure E-cigarette can cause cell damage in lung tissue Keyword: E-Cigarettes; Lung Tissue; Immunohistochemistry; Hematoxylin-Eosin.

The Relationship

Objective: Exposure to electronic cigarette smoke causes an increase of free radicals. Physiologically, the body produces antioxidant superoxide dismutase to neutralize the free radicals. However, an excessive increase of the free radicals will result in an imbalance between the amount of free radicals and antioxidants. The free radicals in the body can trigger lipid peroxidation so that it will result in oxidative stress causing cell damage. Malondialdehyde increase is a marker of oxidative stress in the body. The aim of this research is to understand the changes and the relationship between levels of superoxide dismutase and malondialdehyde in the blood due to exposure to electronic cigarette smoke. Methods: This research is an experimental study using male Wistar rats as experimental animal models. In the study, the exposure to electronic cigarette smoke with different duration of administration was carried out. Next, blood samples were taken to check the levels of superoxide dismutase and malondialdehyde. Results: The results showed a difference in antioxidant levels between antioxidant Superoxide Dismutase and malondialdehyde (p<0.05). Meanwhile the relationship between the two groups showed a strong (r = 0.893) and significant (p = 0.000) relationship. Conclusion: The exposure to electronic cigarette smoke can reduce the level of antioxidant superoxide dismutase and increase the level of malondialdehyde in blood. In addition, changes in the levels of antioxidant superoxide dismutase and malondialdehyde had a strong and significant relationship.

ABSTRACTObjectivesJUUL and earlier generation electronic cigarettes (e-cigs) are promoted as being less hazardous than cigarettes. While JUUL Labs, in particular, claims that switching from smoking to vaping has beneficial impacts, the health effects of such products are not well understood. We investigated whether exposure to JUUL and previous generation e-cig aerosol impairs endothelial function comparably to cigarette smoke.MethodsWe exposed rats to aerosol from Virginia Tobacco flavor JUUL, an e-cig tank system using unflavored freebase nicotine e-liquid, Marlboro Red combustible tobacco cigarettes, or clean air for 10 cycles of 2 second inhalation over 5 minutes. Endothelial function (FMD) was measured pre- and post-exposure. Blood was collected 20 mins post-exposure for serum nicotine analysis.ResultsAerosol/smoke from JUUL, previous generation e-cigs, and cigarettes all impaired FMD. The extent of impairment ranged from 34%-58%, although the differences between groups were insignificant. Nicotine was highest in serum from the JUUL group; for the other e-cig and cigarette groups, nicotine levels were lower and comparable to each other.ConclusionsAerosol from JUUL and previous generation e-cigs impairs endothelial function in rats, comparable to impairment by cigarette smoke.
