Purpose : The purpose of present study was to investigate pulmonary function among smokers and non-smokers, and effect on respiratory muscle training in smoker. Methods : Twenty participants were allocated into smokers group(n = 10) and non-smokers group(n = 10). Pulmonary function was measured by spirometry(Pony FX, COSMED Inc., Italy). The smoker group was compared pulmonary function before and after respiratory muscle training. Results : The results were as follows; There was significant difference on PEF, FEV1/FVC%, FEF25~75%, MEF75% and MEF50% among smoker and non-smokers(p<.05). But, there was not significantly difference after intervention in smokers. Conclusion : The present study found that smoker decreased pulmonary function than non-smokers.

Background: Cigarette smokers have their own motivation and justification to smoke. For example, smoking reduces their stress or enhances their pleasure. This study aimed to identify the (a) prevalence of cigarette smokers among undergraduates in Malaysia, (b) gender differences in nicotine dependence among current smokers, (c) differences in psychological problems (depression, anxiety and stress) based on the status of smoking cigarettes (current, former and non-smokers) and (d) extent to which precipitating factors (tension reduction, addiction, automatism, handling, social interaction, pleasure, and stimulation) predict the smoking behavior among current smokers. Materials and Methods: In this study 780 undergraduate students participated from a private university in Kuala Lumpur and Selangor state in Malaysia. The Depression, Stress and Anxiety Scale, Modified Reason for Smoking Scale and Fagerstrom Nicotine Dependence Test were used to measure psychological problems, predictors of smoking behavior and nicotine dependency among current smokers. Results: The results showed that 14.7%(n=106) of the students were smokers. Current smokers exhibited more psychological problems (depression, anxiety and stress) compared to former and non-smokers. Addiction, tension reduction, pleasure and automatism were predictors of smoking behavior among the current smoking students. Step wise regression analysis showed that smoking behavior was highly predicted by nicotine dependency or addiction. Smoking students were motivated to smoke cigarettes as they believed that it reduced their tension and enhance pleasure. Conclusions: Hence, there is a need for health promotion and anti-tobacco prevention as cigarette smokers experience more psychological problems. Nicotine dependency or addition was one of the major causes for smoking behavior among the student population in Malaysia.

Few changes were found in the mouths of 52 smokers were examined as a part of program to evaluate the oral health of Korean smokers. 52 smokers and 30 non-smokers were performed careful oral examination. In many of smokers, heavy, black deposits are found on the buccal and lingual surfaces of the teeth and leukoplakia were obsreved in 2 subjects and varied merely in the severity of the involvement. Cytologic studies were carried out on 60 oral smears from the hard palate, buccal mucosa, and gingiva. Smears were taken wit a wood spatula scraped over the mucosal surface. After fixation the slides were stained using the papanicolau cells without nuclei. The cornified cells were smaller than the noncornified cells and stained a deep brown or orange as compared with the blue or red of the large, round or polygonal cells in nonkeratinized regions of oral mucosa. Abnormal cell forms, suggestive of malignancy were not found in smears from the mucosa of smokers. Cells with large hyperchromatic nuclei and elongated, spindle-type cells with large nuclei were not observed.

The aim of this study was to assess the association between total vitamin A, retinol and carotene intakes and serum concentration of total carotenoids in Korean male smokers and nonsmokers. Food frequency and nutrient intakes of 64 healthy college students were estimated by the 24 hour recall method and food frequency questionnaire and analyzed by smoking status. Serum total cartenoids and lipid profiles were measured in 28 smokers and 36 nonsmokers. The mean total vitamin A, retinol and carotene intakes of smokers were not significantly different from nonsmokers. However, carotene intakes of the smokers who have smoked more than 5 packyears were significantly lower than those of nonsmokers. Smokers consumed green yellow leafy vegetables more often(P=0.005) and fresh fruits less often(P=0.017) than nonsmokers. The serum total carotenoids of smokers consuming the same amount of retinol and carotene as nonsmokers, 1.79 g/ml, were 17% lower than nonsmokers, 2.15 g/ml(P<0.05). The lipid profiles including total cholesterol, LDL cholesterol, VLDL cholesterol and triglycerides of smokers were not significantly different from nonsmokers, however, the concentration of HDL cholesterol of smokers were significantly higher than that of nonsmokers. The serum carotenoids concentration was positively associated with fruit consumption frequency in smokers, and also was positively associated with green yellow leafy vegetable consumption frequency in non smokers. There were no correlations between dietary and serum carotenoids for smokers as well as nonsmokers. It was concluded that smoking could be inversely related to the serum concentration of carotenoids at constant carotene intakes and smokers might require more carotene to reach the same concentration comparable to nonsmokers.

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.

Purpose: Cigarette smoking causes many kinds of cancer, and it is more closely related with lung cancer, rather than other cancers. Smoking is the leading cause of lung cancer and ninety percent of the smokers are male in China, but there is little published data concerning the psychological responses in the male smokers with lung cancer and its influence on the symptom burden. The aim of the study was to verify the hypothesis that male smokers with lung cancer have more positive attitude and less symptom burden, comparing to male non-smokers. Methods: A total of 194 men with cancer in West China Hospital, Sichuan, China, were assessed by self-administered questionnaire. Psychological response was measured by the Chinese version of Mini-Mental Adjustment to Cancer scale (Mini-MAC), and symptom burden was measured by the physical symptom distress scale from the Rotterdam Symptom Checklist (RSCL). Results: We found that smokers with lung cancer got higher scores in positive attitude and a smaller symptom burden than non-smokers. Patients with education lower than high school got higher scores of positive attitude compared to college graduate patients (p=0.038). Smokers with lung cancer who knew the potential carcinogenicity of cigarette showed less negative emotions (p=0.011). The psychological response was not affected by age, clinical stage, cell type, smoking duration and amount. Conclusions: Male smokers with lung cancer have a more positive attitude and fewer symptoms, comparing to male non-smokers. Appropriate psychological intervention for non-smokers with lung cancer deserves more attention.

This study investigated urinary metabolites of polycyclic aromatic hydrocarbons (PAHs) in the urine of smokers and non-smokers by liquid chromatography triple quordrupole tandem mass spectroscopy (LC/MS/MS). Compounds analyzed for urinary biomarkers of PAHs were five mono-hydroxylated PAHs metabolites; 1-naphthol, 2-naphthol, 1-hydroxypyrene(1-OHP), 3-phenanthrol, 2-fluorenol. Urine samples were pretreated by enzymatic hydrolysis and solid phase extraction method. Smokers were composed of 17 men and five women; non-smokers 17 men and 16 women. Smoking increased urinary concentrations of five PAHs metabolites significantly higher than those of nonsmokers. Statistically significant correlations among the five PAHs metabolites were shown. The results suggest that LC/MS/MS technology should be useful in the environmental health discipline.

The traditional Korean diet, which is high in rice and vegetables, is fast being replaced by a Western style diet as the standard of living goes up. In addition to this, cigarette smoking has taken on serious proportions, especially amongst those of the younger generation. Because Seoul (and it's surrounding areas) is the hub of Education and Business, it is densely populated and heavily polluted Consequently health-related issues and diseases are starting to resemble those prevalent in Western communities. Historically, stomach cancer was the #1 killer-disease in Korea, but nowadays lung cancer ranks either 1st or 2nd on the list of killer-disease in Korea. This is presumably due to the lethal combination of heavy smoking and pervasive air pollution. Despite these disquieting facts, almost no study had been made of the nutritional patterns and dietary habits of smoking and non-smoking young adults in the Seoul area. Therefore the purpose of this study is to compare the dietary and nutritional patterns of young smokers with those of young non-smokers in and around Seoul. This is done with regards to their eating habits and lifestyles, as well as the dietary components that contribute towards maintaining good health. The results showed that compared to non-smokers, smokers manifested irregular eating patterns and also tended to overindulge on fast- or junk foods. In contrast to this, non-smokers enjoyed a healthier diet, which was high in brown rice, grains, legumes, fresh fruit and vegetables, and 'kimchi'. Amongst the male subjects of this study, it was found that smokers consumed significantly less vitamin $B_2$, calcium, and phosphorous than non-smokers. It was also established that in general, stress-generated smoking habits were formed during the high school years of the younger generation. In conclusion: Because smokers maintain a less healthy diet and life-style, it is to recommended that a 'Health Education Program' be developed which could guide young smokers into adopting better dietary habits and life styles.
