Abstract
Background: Cigarette smoke causes various health problems. Therefore, it is necessary to overcome the problem. One solution to these problems is biofilters' use to capture free radicals from cigarette smoke. This study aims to discover the effect of cigarette smoke exposure through a biofilter made from dates, olives, and pomegranates on mice‘s MDA levels.
Methods: The experimental study was performed to compare the result of five different treatments. Exposure of 150 ml of cigarette smoke was given every day using a suction tool (15 times each mouse) for 28 days. It was performed with five controls treatment: negative, positive, date biofilter, pomegranate biofilter, and olive biofilter. Furthermore, the data were analyzed using the one-way ANOVA followed by the Duncan test to discover differences in mice’s MDA levels from each treatment.
Results: The measurement of MDA levels is using the TBA (Thiobarbitaric Acid) test. The sample is obtained from 1.8 grams of the mices' liver in each treatment.The results showed an effect of using date, pomegranate, and olive biofilters on mice's MDA levels. It shows that the best MDA levels were found in date biofilter treatment with a value of 224 ng/ml with a p-value of 0.023.
Conclusion: The results showed that the MDA levels with the Dates and Olives biofilter treatment were better than the negative control. Therefore, these treatment makes the harmful content of cigarette smoke can be minimized.

Abstract
Background: Exposure to cigarette smoke has been associated with pulmonary and reproductive dysfunctions; inflammatory response, oxidative stress and oxidative DNA damage induced by polycyclic aromatic hydrocarbons (PAHs) present in cigarette smoke have been implicated in the pathogenesis of these disorders. The peak expiratory flow rate (PEFR), a biomarker of inflammation and oxidative DNA damage (8-hydroxy-2-deoxyguanosine (8-OHdG), tumor necrosis factor alpha (TNF-α)), reproductive hormones (testosterone (TST), luteinizing hormone (LH), follicle stimulating hormone (FSH)) cotinine and urinary PAH metabolite (1-hydroxypyrene (1-HOP)) were estimated in male active smokers.
Methods: One hundred men aged 20-47 years, comprising 50 active male smokers and 50 non-smokers, were randomly recruited into this comparative cross-sectional study. The PEFR was measured using a peak flow meter, serum levels of cotinine, FSH, LH, TST, TNF-α, and urine 8-OHdG by enzyme-linked immunosorbent assay and 1-HOP by high-performance liquid chromatography. Data analysis was done using a t-test and correlation analysis at p≤0.05.
Results: Smokers had significantly higher cotinine (49.73±31.76 versus 0.51±0.69 ng/ml, p≤0.001), 8-OHdG (16.34±12.10 versus 5.79±2.14 ng/ml, p≤0.001) and lower PEFR (309.20±56.05 versus 452.80±45.76 L/min, p≤0.001) and LH (5.75±2.06 versus 6.97±2.79 mIU/ml, p=0.015) compared to non-smokers. Duration of exposure to cigarette smoke correlated positively with cotinine (r=0.937, p≤0.001) and 1-HOP (r=0.813, p≤0.001) while cotinine correlated positively with 1-HOP (r=0.863, p≤0.001) only in smokers.
Conclusion: Reduced lung function and luteinizing hormone and concurrent increase in oxidative DNA damage associated with exposure to cigarette smoke may suggest the involvement of PAH-induced DNA damage in the development of pulmonary and reproductive impairment in smokers.
