Objectives: This study aimed to identify factors associated with smoking relapse. Methods: The study sample was recruited among subjects who were enrolled in the smoking cessation clinic of a public health center and had succeeded in quitting smoking for at least six months. A total of 159 male subjects were followed via mail survey one year later. The independent variables in the analyses were socio-demographic characteristics, smoking history and behavior, receipt of smoking cessation aids, health behaviors and components of the health belief model (HBM). The dependent variable was smoking relapse assessed one year after quitting. Ordered logit regressions were used to identify factors associated with smoking relapse. Results: The relapse rate of the ex-smokers in our sample was 25.8%, and the occasional smoking rate was 17.0%. Univariate analyses revealed that only factors related to the HBM, such as perceived susceptibility to diseases (p<0.01), perceived severity of diseases (p<0.01), perceived health benefits of not smoking (p<0.01), perceived barriers to quitting smoking due to increasing stress and difficulty in social life (p<0.01), and self-efficacy (p<0.01) were associated with the likelihood of relapse for ex-smokers. Ordered logit analyses yielded two significant factors affecting the likelihood of relapse, the perceived barriers to quitting smoking and self-efficacy. Conclusions: Our results indicate that higher levels of barriers to quitting smoking and lower levels of self-efficacy were significantly related to risk of smoking relapse. These findings may be useful for identifying those at highest risk for relapse and choosing the optimal strategies for prevention of relapse for ex-smokers.
We investigated the effect of smoking on cardiovascular responses during acute dynamic exercise. Eleven college students who had been smoking (duration of smoking: $7.45{\pm}0.90$ years; number of cigarettes per day: $17.72{\pm}1.22$) participated in this study. All subjects completed a graded exercise testing to determine the relative exercise intensity. The cardiovascular responses were measured at rest, and during mild and moderate exercise immediately, 24, and 48 hours after smoking. The same procedures were repeated during 24-h smoking withdrawal. All subjects were continuously instrumented to measure systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), stroke volume (SV), cardiac output (CO), and total vascular conductance (TVC) at rest and during exercise. The results showed that compared to the nicotine abstention, SBP, DBP, MAP, and HR were significantly higher at 24 and 48 hours after smoking ($p$<0.05), and CO was significantly higher at rest and during moderate exercise ($p$<0.05). There were no differences in SV and TVC before and after smoking. Thus, the results suggest that smoking is associated with an exaggerated sympathetic nerve activity during dynamic exercise. Consequently, smoking cessation may help reduce cardiac events, such as stroke and heart attack, during exercise.
Objectives: The purpose of this study is to examine the effect of the raise of cigarette prices by KRW 2,000 at the beginning of 2015 on the change in smoking behavior among male office workers, and to analyze the correlation of various factors including their work behaviors and socio-economic factors with their smoking rate. Methods: In this research, a follow-up observation panel was constituted with 420 smokers as targets from among male office workers at a bank located in Daegu, South Korea. A cross-analysis and ANOVA analysis were carried out in order to examine whether changes in smoking status, amount of smoking, stop-smoking motivation, and reasons for smoking cessation failure after the passage of time since the cigarette price hike were statistically significant. The level of statistical significance was P < 0.05. Results: After the cigarette price hike, among the 420 smokers who were the target of the panel the rate of smoking cessation declined at the time-point of the survey to 15.5%, 12.4%, 8.5%, and 5.7% after one month, three months, six months, and 12 months, respectively. As a result of a follow-up observation of 65 smokers who stopped smoking immediately after the price hike, the actual non-smoking rate declined to 15.5%, 8.3%, 4.4%, and 3.1% after one month, three months, six months, and 12 months, respectively. One (1) year after the cigarette price hike, the non-smoking rate among the 420 smokers reached as low as 3.1% (13 persons). The most important reason for the failure of the attempts to quit smoking was stress for more than 60% of the smokers who attempted to stop. Conclusions: It seems that a powerful anti-smoking policy by the state targeting the nation's workers is necessary. For companies, mediation for workers' job stress can become a strategy for the success of non-smoking attempts. The government seems to require a practical policy to reduce the smoking rate by actively carrying out social, economic, and scientific research to come up with a reduction method for the cigarette hazard, an effective price hike policy, and other non-price policies.

Background and Objectives Reinke's edema is a benign vocal fold disease caused by an edematous laryngeal superficial layer of lamina propria. The first line treatment is cessation of smoking and laryngeal microsurgery. The aim of the study is to evaluate the feasibility and efficacy of percutaneous steroid injection via cricothyroid membrane in patients with Reinke's edema. Materials and Method From Jan 2010 to July 2018, 33 Patients with Reinke's edema managed by vocal fold steroid injection via the cricothyroid membrane were included in this study. We compared medical records of laryngoscopy, stroboscopy and Multi-Dimensional Voice Program analysis at pre-treatment and post-treatment. Subjective voice improvement was evaluated using Voice Handicap Index-30 (VHI-30). Results 75.7% of the patients showed partial response and 6.06% showed complete response. 93.94% were present smokers and only 4 patients ceased smoking after the treatment. In acoustic analysis, the pre-treatment mean value of jitter, shimmer, and noise to harmonic ratio was 2.30±3.21, 9.34±10.37, 1.11±2.90 each. The post-treatment value was 2.20±1.89, 6.96±5.30, 0.20±0.09 respectively and none of the parameters were statistically significant. For subjective symptom improvement, 25 (75.8%) patients showed a better score on post-treatment VHI-30 compared to pre-treatment. Conclusion According to our study, steroid injection is a relatively safe and effective procedure for patients with Reinke's edema. A vocal fold steroid injection via the cricothyroid membrane can be an alternative treatment option for those who are not able to undergo conventional laryngeal microscopic surgery, however cessation of smoking is necessary for effective treatment.
From January 1990 through December 1995, 43 patients underwent diaphragmatic plication for the management of phrenic nerve palsy .complicating various pediatric cardiovascular surgery. Their mean age at plication was 11.1 months and sex ratio was 31 males to 12 females. In order of decreasing incidence, the primary cardiovascular procedures included modified Blalock-Taussig shunt (7), total correction for the Tetralogy of Falloff (7), arterial switch operation (6), unifocalization for the pulmonary atresia with VSD (3), modified Fontan operation (3), VSD patch closure (3) and others. The involved sides of diaphragm were right in 17, left in 2) and bilateral in 3. Extensive pericardial resection with electocauterization of resected margin was thought to be the most common cause of phrenic nerve palsy (20). The interval between primary operation and plication ranged from the day of operation to 98 days (median 11 days). The methods of plication were central pleating technique(plication with phrenic nerve branch preservation) in 41, and other technique In 2. 10 patients died after plication (7: early, 3; late), and the causes of death were thought to be unrelated to plication itself. Among the 36 early survivors, extubation or cessation of positive pressure ventilation could be accomplished between 1 and 24 days postoperatively(mean : 4.5). Cumulative follow-up was 92 patient years without major complications. Postoperative follow-up fluoroscopy was performed in 6 patients, and the location and movement of plicated diaphragms were satisfactory in 5 patients. We concluded that diaphragmatic plication with preservation of phrenic n rve branch could lead to cessation of positive pressure ventilation and complete recovery of diaphragmatic function in the long term, unless the phrenic nerve was irreversibly damaged.
This study was performed to investigate the effect of normal diet with or without naringin supplement on the lipid and antioxidant metabolism in ethanol-treated rats for a short tenn. Male Sprague-Dawley rats were divided into three groups (n=10), which were assigned to one of three dietary categories : $E_8$ : ethanol diet for 8 wks, $E_4N_4$ : ethanol diet for the first 4 wks and normal diet for the last 4 wks, $E_4Nna_4$ : ethanol diet for the first 4 wks and normal diet with naringin supplement for the last 4 wks. Plasma total cholesterol concentrations were significantly higher in ethanol fed rats for 8 weeks. The HDL-C/total-C ratios of the $E_4N_4$ and the $E_4Nna_4$ groups were significantly higher than that of the $E_8$ group, while the atherogenic index was lower in the $E_4N_4$ and the $E_4Nna_4$ groups than in the $E_8$ group. The $E_4N_4$ and $E_4Nna_4$ diets significantly lowered both the hepatic cholesterol and triglyceride levels compared to the $E_8$ group. Accumulation of hepatic lipid droplets was observed to be the highest in the $E_8$ group. In the current study, the naringin supplement to normal diet significantly lowered both the hepatic HMG-CoA reductase and ACAT activities in ethanol pre-treated rats for 4 weeks. Antioxidant enzyme activities were also upregulated when ethanol feeding was ceased. Naringin supplement given for 4 weeks after ethanol cessation resulted in a significant decrease in the plasma cholesterol and hepatic lipids and plasma TBARS as well as the hepatic HMG-CoA reductase and ACAT activities compared to the rats given ethanol diet for the entire 8 weeks. Replacement of normal diet following a short tenn ethanol feeding was effective for the recovery of ethanol-induced fatty liver and for normalizing plasma and hepatic lipid profiles and antioxidant enzyme activities, regardless of an additional phytochemical supplement, naringin. The effect of naringin could seemingly be more evident if its supplementation period had been extended longer than 4 weeks after ethanol cessation.
Chemical burn on the oral mucosa is caused by contact with various chemical products and manifests with localized mucositis, keratotic white lesions, bleeding, and painful tissue surface due to the coagulation of the tissue. Policresulen ($Albothyl^{(R)}$) is a topical antiseptic, commonly used over-the-counter drug for vaginitis, thrush and stomatitis. This drug is highly acidic with pH 0.6, and can act as a strong corrosive agent to oral mucosa. When inadvertently used in oral cavity, it may cause chemical burns of oral mucosa, resulting necrosis and bleeding surface resembling to erythema multifome. A 56 years old female patient presented with the chief complaints of painful ulcerations on the tongue, the upper and lower lips. On intraoral examination, an erythromatous, erosive or ulcerative surface covered with inflammatory exudates or bleeding crust is observed on the anterior half of the tongue and the upper and lower lips. She has occasionally applied the policresulen solution topically on the tongue to relieve pain from recurrent focal glossitis for about 10 years. In this time she applied it broadly and repeatedly to the tongue, the upper and lower lips for the purpose of pain relief by herself without instruction by physician or dentist. After cessation of policresulen application, the oral mucosa was rapidly recovered with use of topical steroids. In 2 weeks the lesions subsided completely. In summary, inadvertent use of $Albothyl^{(R)}$ on oral mucosa may result in chemical burn, causing mucosal erosion, ulceration and inflammation. It can be recovered by topical use of corticosteroid for 2 weeks after cessation of using $Albothyl^{(R)}$.
The use of chlorinated water in swimming pools produces elevated chloroform levels in the water and air of the pools which can cause chloroform body burden of swimming individuals. Present study confirmed the chloroform body burdens from a 40-min swimming and evaluated the decay of chloroform breath concentration after the cessation of a 60-min swimming. Air and water concentrations were measured in the pools. The water and air chloroform concentrations ranged from 18.1 to 25.3 ${mu}g/l$ and from 30.9 to 60.7 ${\mu}g/m3$ for the confirmation study, respectively. The breath level after 40-min swimming was about 64 to 266 folds higher than the corresponding background breath. The breath concentration after the 40-min swimming ranged from 10.5 to 21.3 ${\mu}g/m3$, while that prior to the corresponding swimming ranged from 0.07 to 0.19 ${\mu}g/m3$. In addition, the post-exposure breath level varied with the subjects who swam in the pool on the same visiting day. Breath concentration increased gradually during 60-min swimming, then decreased rapidly within 5 minutes after the cessation of exposure, after that, decreased slowly, and finally approached to a background breath level at 1-2 hr after exposure.

Background: Varenicline, a selective partial agonist/antagonist of the ${\alpha}4{\beta}2$ nicotinic receptor, has proven effectiveness for smoking cessation by several randomized, controlled trials. Because few studies have evaluated the long-term efficacy of varenicline, we tried to evaluate the smoking status of varenicline users up to 3 years after the initial prescription of the drug. Methods: We interviewed varenicline users who were prescribed the drug from June 2007 to May 2010 by telephone, from June 2010 to May 2011. Results: One-hundred and thirty-three of 250 varenicline users (53.2%) were available for the survey. Seven-day continuous abstinence from smoking was adhered to by 17 of 39 respondents (43.6%) at 1 year, and 11 of 36 (30.6%) and 19 of 58 (32.8%) at 2 and 3 years since the first use of varenicline, respectively. Compared to current smokers, successful quitters were older (55.0 years vs. 49.9 years, p=0.01), had better compliance to the 12-week course (27.7 vs. 9.3%, p=0.01), and had taken varenicline longer (10.1 vs. 5.9 weeks, p=0.01). Fifty-four of 71 current smokers (76.1%) were willing to stop smoking in the near future. The preferred ways to cease smoking were will-power (48.1%), varenicline (25.9%), nicotine replacement therapy (11.1%), and others (14.9%). Conclusion: Smokers should be encouraged to stick to the proven way for recommended period of time for successful cessation of smoking.
Difference in sensitivity of Eleocharis kuroguwai tubers to bensulfuron- methyl{methyl 2-[[[[[(4, 6-dimethoxy-2-pyrimidinyl) amino] carbonyl] amino] sulfonyl] methyl] benzoate} at different burial depths were determined with respect to tuber emergence, sprouting of lateral buds, carbohydrate consumption of the tuber, and growth and new tuber production of the regrown plants. Days required to regrowth from the growth cessation due to bensulfuron-methyl were shorter in shallow-buried tubers than in deep-buried tubers. With application of bensulfuron-methyl shallow-buried tubers consumed less carbohydrate in the tuber than deep-buried tubers as compared with in deep-buried tubers during the period of growth cessation and greater regrowth also occurred in the former. Fast and great regrowth in shallow-buried tubers resulted in great production of dry matter and new tubers. However, the differences obtained were not due to bensulfuron-methyl, but due mainly to ecological emergence and growth characteristics of tubers buried at different depths.
