The purpose of this study was examine the relationship between smoking, general characteristics, and serum lipids in the normal adult. The subjects consist of 6,800 persons (male ; 4,309(63.4%), female ; 2,491(36.6%)) in A hospital in Kyungki-Do. The collected data were analyzed using T-test, and Multiple Regression by SPSS/WIN program. The result were following ; 1. Cigarette smoking was associated with decreased serum HDL cholesterol level (p<.001). 2. Serum LDL cholesterol level was not statistically correlated with smoking tend to level by 5.77mg/dl respectively. 3. Cigarette smoking was associated with elevated serum Triglyceride level (p<.001). 4. By using regression, HDL cholesterol level was negatively correlated with obesity and alcohol.. HDL cholesterol level was positively correlated with exercise. LDL cholesterol level was positively correlated with diet and obesity.　Triglyceride level was positively correlated with obesity and　alcohol. In conclusion, Smoking was the most correlated with Triglyceride among the serum lipid and Serum lipid was the most correlated with obesity. Thus, it is necessary to quit smoke and weight control for prevention from disease such as coronary heart disease and lung cancer.

Scientific evidence on all aspects of smoking amongst youth is very important for designing appropriate interventions to reduce smoking among this vulnerable population. This paper describes current access to anti-smoking information among school children aged 13 to 15 years in Vietnam in 2014 and examines its potential impact on preventing smoking initiation. The data used in this paper were obtained from the 2014 Global Youth Tobacco Survey (GYTS) in Vietnam. Students were asked questions about their level of awareness of anti-smoking information from various sources in the past 30 days and about lessons in school regarding the dangers of tobacco use during the last 12 months. Those who have never smoked were asked "whether or not they thought about avoiding cigarettes because of health warnings on cigarette packages" and answers were analyzed in combination with data on access to anti-smoking information from other sources. The prevalence of exposure to antismoking campaigns was high among school children in Viet Nam: 55.3% of current smokers reported thoughts of smoking cessation because of health warnings on cigarette packages; 60.5% of never smokers avoided initiating smoking because of the same health warnings. The potential impact of graphic health warnings to prevent school-aged children from smoking initiation would be stronger if there was concurrent access to anti-smoking programs on the dangers of tobacco use in schools. However, school education for tobacco prevention and control has not been as strong as expected. A more comprehensive school curriculum on tobacco prevention and control is recommended to reinforce antismoking messages among school children.

Objectives: Epidemiological studies have shown that molecular mechanisms underlying the development of lung cancers differ between smokers and unsmokers. Aberrant promoter methylation in some tumor suppressor genes is frequent in lung tumors from smokers but rare in those from non-smokers. Recently, many studies have investigated the association between cigarette smoking and RASSF1A gene promoter hypermethylation in lung cancer patients, but a unanimous conclusion could not be reached. We therefore performed this meta-analysis to derive a more precise estimation of any association. Study Design: An electronic search of PubMed and Chinese Biomedicine databases was conducted to select studies. A total of 19 case-control studies were chosen, and odds ratios (ORs) with confidence intervals (CIs) were used to assess the strength of associations. Results: The case-control studies covered 2, 287 lung cancer patients: 63.4%(1449) of the patients were smokers, 36.6% (838) were unsmokers. The overall results suggested that smokers with lung cancer had a 1.297-fold (95% CI: 1.066~1.580, p=0.010, p=0.087) higher risk for RASSF1A gene hypermethylation than the non-smokers. In the stratified analysis, an increased risk of RASSF1A gene hypermethylation in smokers than in non-smokers was found in Asian (OR=1.481, 95%CI: 1.179~1.861, p=0.001, p=0.186). Conclusions: This meta-analysis supports the idea that RASSF1A gene hypermethylation is associated with cigarette smoking-induced lung cancer.

Background: The scientific evidence relating to the burden of oral diseases attributable to tobacco use has been reviewed and the need for a well-structured dental teaching program concentrating on oral cancer education and tobacco cessation interventions has been emphasized. The aim of our study was to evaluate the awareness of oral cancer and perception of tobacco use cessation counseling among dental students at all study levels in India, Saudi Arabia, the United Arab Emirates, and Yemen. Materials and Methods: A structured, pre-tested, self-administered 15-item questionnaire was used to conduct a cross-sectional survey. Data analyses including percentages, frequency distributions and tests of chi-square were generated. Results: A total of 621 (97.6%) Indian, 493 (96.5%) Saudi, 194 (96.5%) Yemeni and 187 (98.4%) United Arab Emirates respondents recognized the association between oral cancer and cigarette smoking. Although more than 96% of the students surveyed recognized the association between oral cancer and cigarette smoking and about 55% reported cigarette smoking as one of the etiological factors of oral cancer, more than 66% of students who reported cigarette smoking as an etiological factor of oral cancer disagreed/strongly disagreed with all the statements concerning tobacco use cessation. Conclusions: A higher level of oral cancer awareness did not have a positive impact on the perception of tobacco use cessation counseling among the sample surveyed.

Objectives Cigarette smoking is associated with carcinogenesis owing to the mutagenic and genotoxic effects of cigarette smoke. The aim of this study was to evaluate the mutagenic and genotoxic effects of Korean cigarettes using in vitro assays. Methods We selected 2 types of cigarettes (TL and TW) as benchmark Korean cigarettes for this study, because they represent the greatest level of nicotine and tar contents among Korean cigarettes. Mutagenic potency was expressed as the number of revertants per ${\mu}g$ of cigarette smoke condensate (CSC) total particulate matter whereas genotoxic potency was expressed as a concentration-dependent induction factor. The CSC was prepared by the International Organization for Standardization 3308 smoking method. CHO-K1 cells were used in vitro micronucleus (MNvit) and comet assays. Two strains of Salmonella typhimurium (Salmonella enterica subsp. enterica ; TA98 and TA1537) were employed in Ames tests. Results All CSCs showed mutagenicity in the TA98 and TA1537 strains. In addition, DNA damage and micronuclei formation were observed in the comet and MNvit assays owing to CSC exposure. The CSC from the 3R4F Kentucky reference (3R4F) cigarette produced the most severe mutagenic and genotoxic potencies, followed by the CSC from the TL cigarette, whereas the CSC from the TW cigarette produced the least severe mutagenic and genotoxic potencies. Conclusions The results of this study suggest that the mutagenic and genotoxic potencies of the TL and TW cigarettes were weaker than those of the 3R4F cigarette. Further study on standardized concepts of toxic equivalents for cigarettes needs to be conducted for more extensive use of in vitro tests.

본 연구는 연소담배와 비교해 서로 다른 가열담배(heated tobacco products, HTPs) 사용 시 혈역학적 지표들의 급성 반응을 비교하고, 급성 HTPs 에어로졸 노출이 심장 자율신경조절(cardiac autonomic regulation, CAR)에 미치는 영향을 탐색하려는 목적으로 수행되었다. 또한, 서로 다른 연초 스틱 간 급성 심혈관 효과의 비교 검증을 목표로 하위연구를 설계했다. 외관상 건강한 남성 흡연자 16명은 개방표지, 무작위 교차시험으로, 최소 48시간 세척기간과 함께 비-흡연(non-smoking, NS), 담배 흡연 및 서로 다른 두 가지 HTPs 사용 세션을 각각 수행했다. 하위연구는 NS와 함께 서로 다른 두 가지 연초 스틱 간 급성 심혈관 효과를 비교하기 위해, 참여자 중 8명을 대상으로 실시되었다. 수축기와 확장기 혈압 및 CAR을 반영하는 심박변이도(heart rate variability, HRV)가 각 세션 시작 전, 제품 사용 중 그리고 사용 후 30분까지 평가되었다. NS 동안 혈역학적 변화는 통계적 차가 없었으나, HTPs 에어로졸에 급성 노출은 담배 연기와 상응하는 수축기와 확장기 혈압의 유의한 증가를 초래했으며, 이들 지표에서 HTPs 기기 간 통계적 차는 없었다. 연소담배와 HTPs 사용 후 통계적으로 유의한 심장 교감신경활동(cardiac sympathetic nerve activity, CSNA)의 급성 증가와 심장 미주신경 긴장도(cardiac vagal tone, CVT)의 급격한 저하가 나타났다. 사용 기기와 독립적으로 HTPs 사용에 따른 CSNA와 CVT 반응은 연소담배와 통계적 차가 없었다. 서로 다른 두 가지 연초 스틱은 NS와 비교해 혈역학적 지표들의 유의한 증가를 유도했으나, 연초 스틱 간 통계적 차는 없었다. CVT는 두 가지 연초 스틱 사용에 따라 유의하게 감소했으며, 연초 스틱의 종류에 따라 CVT 저하에 통계적 차가 있었다. 이상의 결과들은 HTPs 에어로졸 노출이 사용 기기와 독립적으로 연소담배와 동등한 급성 심혈관 효과를 유도할 수 있으며, 연초 스틱의 종류에 따라 급성 CAR 저하가 강화될 수 있음을 시사한다.

Background: AMP-activated protein kinase (AMPK) not only functions as an intracellular energy sensor and regulator, but is also a general sensor of oxidative stress. Furthermore, there is recent evidence that it participates in limiting acute inflammatory reactions, apoptosis and cellular senescence. Thus, it may oppose the development of chronic obstructive pulmonary disease. Methods: To investigate the role of AMPK in cigarette smoke-induced lung inflammation and emphysema we first compared cigarette smoking and polyinosinic-polycytidylic acid [poly(I:C)]-induced lung inflammation and emphysema in $AMPK{\alpha}1$-deficient ($AMPK{\alpha}1$-HT) mice and wild-type mice of the same genetic background. We then investigated the role of AMPK in the induction of interleukin-8 (IL-8) by cigarette smoke extract (CSE) in A549 cells. Results: Cigarette smoking and poly(I:C)-induced lung inflammation and emphysema were elevated in $AMPK{\alpha}1$-HT compared to wild-type mice. CSE increased AMPK activation in a CSE concentration- and time-dependent manner. 5-Aminoimidazole-4-carboxamide-1-${\beta}$-4-ribofuranoside (AICAR), an AMPK activator, decreased CSE-induced IL-8 production while Compound C, an AMPK inhibitor, increased it, as did pretreatment with an $AMPK{\alpha}1$-specific small interfering RNA. Conclusion: $AMPK{\alpha}1$-deficient mice have increased susceptibility to lung inflammation and emphysema when exposed to cigarette smoke, and AMPK appears to reduce lung inflammation and emphysema by lowering IL-8 production.

배경 및 목적 : 만성폐쇄성 폐질환은 대부분 후천적으로 발생하며, 흡연은 가장 중요한 유발인자이다. 흡연력이 있는 만성폐쇄성 폐질환 환자들이 임상적 그리고 병리학적으로 차이가 분명한 만성기관지염과 폐기종의 두가지 형태로 진행한다는 사실은 단순한 흡연력 이외에 흡연과 관계가 있는 다른 인자가 관여함을 시사하고 있다. 저자들은 흡연력이 있는 남자 중 만성폐쇄성 폐질환으로 진단된 환자를 대상으로 흡연력과 흡연습관 및 행태를 조사하여 만성기관지염과 폐기종의 발생과 관련이 있는 흡연습관을 찾아보고자 하였다. 방 법 : 영남대학교 부속병원 호흡기내과를 방문하였던 환자 중 만성폐쇄성 폐질환으로 진단되고 흡연력이 있는 333명의 남자(폐기종 ; 143명, 만성기관지염 ; 190명)를 대상으로 흡연력에 대하여 설문조사를 하였다. 그러나, 악성 폐종양, 간질성 폐질환, 기관지 확장증, 진폐증, 폐허탈, 흉수 및 흉막유착 등이 있는 경우와 폐렴이나 폐결핵 등 현증 감염성 질환이 있는 경우, 그리고 1초간 노력성 호기량($FEV_1$)이 ${\beta}_2$ 항진제 사용후 10% 이상 증가하는 경우는 대상에서 제외하였다. 결 과 : 만성기관지염 환자에 비해 폐기종 환자는 평균 나이가 많고, 흡연량 및 절대흡연량이 많았으며, 흡연을 일찍 시작하였고, 담배연기를 갚이 흡입하는 경향이 있었다(p<0.01). 또한 필터가 없는 담배를 피운 기간도 폐기종환자가 훨씬 길었다(p<0.01). 그러나 피우는 담배의 평균길이는 두 질환 사이에 유의한 차이가 없었다. 나이와 흡연력 및 절대흡연량에 대하여 보정한 후 연기의 흡연정도를 비교한 결과 역시 폐기종 환자에서 더 깊게 흡입하는 경향이 있었다. 결 론 : 폐기종의 발생은 담배연기의 흡입정도와 관계가 깊으며, 담배연기에 대한 폐포의 지속적인 노출은 폐기종 발생에 중요한 요인으로 작용할 것으로 생각된다.
