In order to investigate the effect of smoking on serum lipid pattern and nutrient intake, the subjects, 134 smokers and 113 nonsmokers, were selected from college men student in Kwangju area. We examined the serum lipid pattern of 15 smokers and 18 non-smokers who agreed to venipunture among the subjects and also examined nutrients intake. The results obtained were as follows ; Mean concentrations of 새심 cholesterol, HDL-cholesterol and LDL-cholesterol were 187$\pm$12.1mg/dl, 41.5$\pm$1.7mg/dl, and 87.3$\pm$7.4mg/dl in smokers and 182.6$\pm$8.2mg/dl, 45.5$\pm$1.5mg/dl, and 96.3$\pm$4.3mg/dl in nonsmokers, respectively. The total energy intake was 2264kcal/day and mean constitutional rationof protein, fat and carbohydrate was 12.7 : 24.8 : 62.5 in smokes and 2287kcal/day, 14.1 :25.4 : 60.5 in nonsmokers, respctively. Mena daily intakes of calcium, iron, vitamin C and vitamin A were 612.2mg, 15.7mg, 48.2mg 2029.4 IU in smokers and 629.4mg, 15.3mg, 68.4mg 2339.1 IU in nonsmokers, respectively. Vitamin C intake was significantly different at p<0.05 between the smokers and nonsmokers. Intakes of cholesterol, SFA and MUFA were not significantly different between the two groups. Mean daily PUFA intake of smokers and nonsmokers were 5.5g and 6.9g respectively. PUFA intake was significantly different at p<0.05 between the two groups. The results of this study showed that smoking have a tendency to raise coronary heart disease occurrence in the respect of serum lipid levels and vitamin C, PUFA intake were significantly different.
Smoking damages nonsmoker's health who have been exposed to passive smoking as well as smoker's own health. Passive smoking can cause serious health damage to particular groups, such as the old aged, children and pregnant women. The purpose of this study is to investigate the relationship between nicotine concentrations in environmental tobacco smoke (ETS) and urinary cotinine concentrations of nonsmokers exposed to ETS, and to provide basic information related to health risk assessment. The results of this study were summarized as follows: 1. When 180 cigarrette were smoked during S hours (high concentrations exposure) in 132 m$^3$chamber, mean concentrations of nicotine in ETS showed 263.52 $\mu\textrm{g}$/m$^3$${\pm}$51.93. When 45 cigarretts were smoked (low concentrations exposure), it was 69.43${\pm}$8.96 $\mu\textrm{g}$/m$^3$. 2. The urinary cotinine concentrations of each times (0, 2.5, 5, 17 and 24 hours) in nonsmokers ranged from 0.27∼12.52 ng/ml in high concentrations exposure and 0.22∼2.28 ng/ml in low concentrations exposure. Mean while the total urinary cotinine concentrations during 24 hours ranged from 11.62∼31.65 ng/ml in high concentrations exposure and 3.45∼5.64 ng/ml in low concentrations exposure. 3. The correlation equation and coefficient between cotinine concentrations in nonsmokers' urine (y) and nicotine concentrations in ETS (x) was y=0.421+0.0171x and 0:875 (p<0.01) respectively, 4. The quantity of nonsmokers' smoking exposure by passive smoking can be assumed as based on the estimation of nicotine concentrations in ETS by measuring cotinine concentrations of nonsmokers' urine.
The ultimate goal of periodontal therapy is the regeneration of periodontal tissue which has been lost due to destructive periodontal disease. Various periodontal procedures have been used throughout the years in an attempt to reestablish attachment of periodontal tissues to root surfaces affected by periodontitis. Flap debridement surgery has been demonstrated to be a successful procedure in gaining the probing attachment level and reducing probing depth. A tendency towards impaired wound healing following periodontal procedures in smokers has been clinically documented. But, previous clinical studies on healing response in smokers are based on a retrospective design. The purpose of this study was to evaluate the treatment outcome following flap debridement surgery in smokers compared to nonsmokers. 25 patients with moderate to advanced periodontitis were included for study. Among these patients, 13 patients were smokers, and 12 patients were nonsmokers. Mucoperiosteal flap was raised with the sulcular incision. No antibiotic treatment was administered postsurgery. The patients was recalled at monthly intervals during a period of 6 months following the surgery. The patients were received supragingival scaling and oral hygiene reinforcement. All the recordings, including modified O' Leary plaque control record, bleeding on probing, probing pocket depth, probing attachment level,were recorded, presurgery and 6 months postsurgery. The changes of all the recordings at 6 months after flap debridement surgery revealed the following results: 1. PI on all the dentitions and surgical sites showed no statistical significance between smokers and nonsmokers at presurgery. But, smokers demonstrated a significantly lower % of PI than nonsmokers at 6 months postsurgery. 2. Smokers demonstrated a greater % of BOP sites than nonsmokers on the surgical sites and all the dentitions, presurgery and 6 months postsurgery. But, there was no statistical significance between two groups. 3. Smokers exhibited significantly less reduction of probing depth in the 3 mm or less probing pocket depth(PPD) group, 6mm or more PPD group and total PPD group when compared to nonsmokers at 6 months postsurgery. 4. Smokers exhibited significantly less gain of probing attachment level(PAL) in the 3mm or less PPD group, 6 mm or more PPD group and total PPD group when compared to nonsmokers at 6 months postsurgery.
Objectives : The purpose of this study was to investigate distribution of periodontal status and treatment need between smokers and nonsmokers. Methods : Interview and measurement was completed by 82 smoker students and 59 nonsmoker students in Taegu Health College from April 1 to 31, 2001. The community periodontal index of treatment needs(CPITN) was analyzed by percentage. Results : In distribution of CPITN by age, almost all subjects had periodontal diseases except for aged 20~24 years nonsmokers(4%). Smoking 5 cigarettes per a day, up to 10, and above 10 increased 5.3%. 7.1%. and 9.5% in 4 score of CPITN, respectively. In years of smoking, smokers who had above 5 years(13.5%) were higher than below those(6.7%), 20% for smoker who take tooth brushing once per a day had higher than 8.3%(or three in depth of pocket above 6mm. In treatment need, all subjects should take education(or oral health except for aged 20~24 years nonsmokers(4%), 96% of smokers and nonsmokers were need scaling. Conclusion : This study indicated that treatment needs for periodontal diseases and scaling in smoker were higher than nonsmoker those.
Cessation and re smoking is recursive and addictive behaviors. Understanding differences in awareness of smokers and nonsmokers is fundamental to devise smoking policies. Research is focused on male adult's choices of educators and motivation level by personal attributes and awareness. There was a difference in awareness of smoking policies between smokers and nonsmokers. Community health centers and physicians were preferred for antismoking educator but not different between smokers and nonsmokers. Motivational levels of cessation in pictures of lung cancer, dental therapy, cigarette taxation, smoking area restriction and social marketing were statistically significant. The results indicate that male adult smokers are Motivated to quit smoking by those five contributors[P=.000].
This study was done to compare serum levels of lipids, trace minerals, ceruloplasmin and ferroxidase activity between female college smokers and nonsmokers. Serum levels of lipids, Cu, Zn, ceruloplasmin and ferroxidase activity were determined in 33 smokers and 42 nonsmokers residing in the Seoul area. Serum levels of TG, total cholesterol and HDl-cholesterol were measured using test kits. Serum Cu Zn were determined by the AAS. Serum ceruloplasimin level and ferroxidase activity were determined by spectrophotometric methods. All data were statistically analyzed by the SAS PC package program. Mean and standard errors were calculated for each item, and the significance of the difference between two groups was evaluated by Student's t-test at p〈0.05. There was no significant difference in levels of total cholesterol, TG, VLDL-cholesterol, LDL-cholesterol, LDL/HDL and atherogenic index, but HDL-cholesterol level was significantly lower(p$\ll$0.05) in female college smokers than in nonsmokers. Serum zinc level showed no significant difference, whereas copper level was significantly higher in smokers, consequently yielding higher Cu/Zn ratio in smoking college women. Ceruloplasmin level was 32.6mg/dl in smoking college women, which was significantly higher(p$\ll$0.05) than that of 28.6mg/dl in nonsmokers. However, cerulopasmin ferroxidase activity, 0.34U/mg in nonsmokers was higher(p$\ll$0.05) than that of 0.29U/mg in smokers. From these results, it is confirmed that cigarette smoking itself has a very detrimental effect on health and mineral nutritional status although the smoking history is relatively short among college women(pack-years=1.7). (Korean J Community Nutrition 2(4) : 515-522, 1997)
In order to evaluate the effect of cigarette smoking on the pharmacokinetics of theophylline in Koreans, doses of 4.5 to 5.0 mg/kg of theophylline, as injectable aminophylline, were administered to 12 normal young volunteers (male, 22 to 35 yrs;mean, 26 yrs) through intravenous infusion over 30 minutes, and pharmacokinetics of theophylline were tested. Among subjects, six were nonsmokers and the other were smokers (range 1 to 2 packs/day). Also the correlations between plasma and saliva theophylline concentrations were investigated by determining the concentrations of theophylline in saliva simultaneously at each plasma sampling time. The total body clearances of theophylline in smokers (Mean${\pm}$SD, 0.0578${\pm}$0.0092 L/hr/kg)were appreciably higher than thoxe of nonsmokers (Mean${\pm}$SD, 0.0359${\pm}$0.0063 L/hr/kg), and the half-lives of theophylline in smokers averaged 5.36${\pm}$1.22hr, and significantly shorter than those of nonsmokers which averaged 9.14${\pm}$1.73hrs(p<0.005). But the apparent volumes of distribution of theophylline did not show any significant difference between smokers (Mean${\pm}$SD,0.44 ${\pm}$0.05L/kg) and nonsmokers (Mean${\pm}$SD, 0.46${\pm}$0.05L/kg). The average concentration ratios in saliva and plasma were 0.61 in smokers and 0.56 in nonsmokers after 2 hrs following drug administrations, and the smoker group had a slightly higher value of ratio(S/P) than the nonsmoker group (p<0.05). The correlations between saliva and plasma theophylline concentration in smokers were r=0.852(p<0.0005) within 2 hr and r=0.985(p<0.0005) after 2 hrs and also those of nonsmokers were r=0.729(p<0.0005) within 2 hrs and r=0.957(p<0.0005) after 2 hrs starting the infusion. From the results, it was found that smoking cigarettes had significantly increased the clearance of theophylline and that the relationships between saliva and plasma theophylline concentrations in all subjects were better after 2 hrs than within 2 hrs starting the infusion of aminophlline.
This study was done to investigate the effect of adolescent smoking on dietary intakes and nutritional status of serum lipids and antioxidant vitamins. Subjects were 82 somkers whose average pack-year was 0.73, and 85 nonsmokers of male technical high school students in Seoul. Anthropometric measurement was performed and % body fat was also analyzed by Bioelectrical Impedance Fatness Analyzer(GIF-891). Dietary intakes and habits were examined through questionnaires and nutrient intakes were analyzed by Computer Aided Nutritional (CAN) analysis programs. Serum TG and total cholesterol levels were measured by Spotchem sp-4410 and serum HDL-cholesterol levels were measured by test kit. serum vitamin C level was measured by 2,4-dinitrophenylhydrazine method and serum levels of vitamin A and vitamin E were measured by HPLC. All data were statistically analyzed by SAS PC package program. There was a significant difference in body fat percentage and systolic blood pressure while other anthropometric measurements were not different between smokers and monsmokers. Caloric intakes(2335㎉) in adolescent smokers tended to be higher than that of nonsmokers (2,175㎉) but the difference was not statistically significant. Intakes of protein(76.67g) and niacin(16.49㎎) in adolescent male smokers were significantly higher(P<0.05) than those of nonsmokers although other nutrient intakes were not significantly different. Analysis of serum lipids showed that serum HDL-cholesterol level of smokers was significantly different. Analysis of serum lipids showed that serum HDL-cholesterol level of smokers was significantly lower(p<0.05) than that of nonsmokers, whereas other lipid levels were not significantly different. Serum vitamin C level was also significantly lower(p<0.05) in adolescent smokers than in nonsmokers. In addition, serum vitamin E level, which was 7.85㎎/1 in smokers, was lower than that of 9.20㎎/1 in nonsmokers(p<0.05) while serum vitamin A level was not significantly different between the two groups. These results indicate that cigarette smoking in adolescence decreases serum levels of HDL-cholesterol, vitamin C and vitamin E even thoughth their smoking history is very short.

Background: The lifetime risk of lung cancer incidence due to radiation for nonsmokers is overestimated because of the use of the average cancer baseline risk among a mixed population, including smokers. In recent years, the generalized multiplicative (GM)-excess relative risk (ERR) model has been developed in the life span study of atomic bomb survivors to consider the joint effect of radiation and smoking. Based on this background, this paper discusses the issues of radiation risk assessment considering smoking in two parts. Materials and Methods: In Part 1, we proposed a simple method of estimating the baseline risk for nonsmokers using current smoking data. We performed sensitivity analysis on baseline risk estimation to discuss the birth cohort effects. In Part 2, we applied the GM-ERR model for Japanese smokers to calculate lifetime attributable risk (LAR). We also performed a sensitivity analysis using other ERR models (e.g., simple additive (SA)-ERR model). Results and Discussion: In Part 1, the lifetime baseline risk from mixed population including smokers to nonsmokers decreased by 54% (44%-60%) for males and 24% (18%-29%) for females. In Part 2, comparison of LAR between SA- and GM-ERR models showed that if the radiation dose was ≤200 mGy or less, the difference between these ERR models was within the standard deviation of LAR due to the uncertainty of smoking information. Conclusion: The use of mixed population for baseline risk assessment overestimates the risk for lung cancer due to low-dose radiation exposure in Japanese males.

Objectives : The purpose of the study is to investigate the self awareness of oral health, dental calculus and gingivitis according to smoking in soldiers. Methods : A self-reported questionnaire was filled out by 601 soldiers in Jeonnam military unit from April 7 to 23, 2013. The screening for oral examination was performed in the soldiers. The data were analyzed for frequency analysis and chi-square test by using SPSS 21.0 program. Results : The self awareness of smoking on oral health accounted for 27.0% in good status in nonsmokers, 23.5% of the past smokers answered good, and 16.5% of the smokers answered good. Approximately, 68.7% had dental calculus(p<0.05). The smokers tended to have more gingivitis than the nonsmokers and the past smokers(p<0.05). Conclusions : Smokers had low level of self awareness of oral health than the nonsmokers and the past smokers.
