Objectives : We wanted to evaluate the relationship between obesity and left colonic adenomatous polyps in Korean adult men. Methods : This study was conducted among 575 adults men (aged between 40 and 69), who had colonoscopy done from January to December 2002 during a routine health examination at Health Promotion Center, Ulsan University Hospital. The patients' colons were examined up to splenic flexure by using fiberoptic colonoscopy. A questionnaire survey on behavioral factors and physical measurements were also done. The body mass index (BMI) and waist-hip ratio (WHR) were used as the indices of obesity. The BMI was categorized into three levels: normal ($BMI{\leq}22.9$), overweight ($23{\leq}BMI{\leq}24.9$), and obese ($BMI{\geq}25.0$). The WHR was categorized into four levels with cutoff points at the 30th, 60th, and 90th percentile of the control group. Age, education, smoking, alcohol use and exercise were controlled for by performing multiple logistic regression analysis. Results : There were 99 cases of colonic adenomatous polyps. Four hundred seventy six subjects with normal colonoscopy findings served as the control. The BMI and WHR were associated with the adenomatous polyps (odds ratio, 1.81 [95% CI=1.02-3.19] for a $BMI{\geq}25.0$ as compared with a $BMI{\leq}22.9$, odds ratio, 3.94 [95% CI=1.77-8.77] for a $WHR{\geq}0.95$ as compared with a $WHR{\leq}0.86$). The BMI was not associated with the risk of adenomatous polyps after additional adjustment was made for the WHR, but the association between the WHR and adenomatous polyps was still positive and independent of the BMI (odds ratio, 4.15 [95% CI=1.63-10.59]). Conclusions : The results support that obesity, and particularly abdominal obesity, can be associated with an increased risk of incurring colonic adenomatous polyps.
The study examined the relationship between the compressed breast thickness and Average Glandular Dose (AGD) among 1,969 outpatients who went through breast X-ray in a university hospital for 10 months from July 1st, 2007 to April 30th, 2008. Then it analyzed the result acquired from 3,900 cases of Cranio-Caudal (CC) view, especially, when the breasts were compressed (13-15daN). The following is the conclusion driven from the relationship analysis. 1. The subjects aged in 40s and 50s were 2,679 out of 3,900 cases and this figure was 68.69% in all. 2. In terms of distribution depending on focus/filter, 41.0% was Mo/Mo, 34.8% was Mo/Rh, and 24.2% was Rh/Rh. 3. In terms of compressed breast thickness depending on focus/filter, the average thickness was 26.91 mm at Mo/Mo, 38.84 mm at Mo/Rh, and 48.80 mm at Rh/Rh. The average thickness of the entire cases was shown to be 36.27 mm. 4. AGD depending on focus/filter was 1.27 mGy at Mo/Mo, 1.55 mGy at Mo/Rh, and 1.42 mGy at Rh/Rh. The average glandular dose of the entire cases was shown to be 1.43 mGy. 5. The relationship of AGD depending on compressed breast thickness at Mo/Mo was y=0.0318x + 0.470 while it was y=0.0206x + 0.709 at Mo/Rh and y=0.0248x + 0.335 at Mo/Rh. It was highly influenced by the compressed breast thickness, however, more variation was detected at Mo/Mo depending on breast thickness.
Between 1987 and 1995, eleven patients with severe chronic corrosive stenosis of the hypopharynx and esophagus underwent surgical restoration of digestive continuity at Inje University Seoul Palk Hospital. There were 7 male and 4 female patients aged from 21 to 47 years (mean, 34 years). The caustic material was acid in 6 patients and alkali in 5 patients. The esophagus was reconstructed using the right colon In 9 and left colon in 2. The cervical approach and the side of proximal anastomosis depended on the status of the pyriform slnus of the hypopharynx. In the neck, J-formed incision was made along the sternocleidomastoid muscle. The sternohyoid and thyrohyoid muscles were divided transversely to expose the thyroid cartilage. Hypopharyngeal opening for proximal anastomosis was made by reverse triangular formed resection of the thyroid cartilage after elevation of perichondrium. Immediately after operation, dysphagia and aspiration into trachea were common, so training of swallowing was required. Feeding gastrostomy was usually maintained for 3 months until restoration of swallowing function was confirmed . There was graft necrosis in 3 patients, who were treated with jejunal free graft. Revisional procedures for stenosis of cervical anastomosis in B patients consisted of widening of pharyngocecostomy site in 2 and resection of adhesive band in one. Return of normal swallowing assuring normal nutrition was obtained in 10 of 11 cases.

Background: Extracorporeal membrane oxygenation (ECMO) has recently attracted interest as a treatment for severe acute respiratory distress syndrome (ARDS). However, the outcomes of this procedure in post-surgical settings have not yet been characterized. In this study, we evaluated the outcomes of ECMO in patients with severe postoperative ARDS. Methods: From January 2007 to December 2012, a total of 69 patients (aged $58.3{\pm}11.5$ years, 23 females) who underwent venovenous ECMO to treat severe postoperative ARDS were reviewed. Of these patients, 22 (31.9%) had undergone cardiothoracic surgery, 32 (46.4%) had undergone liver transplantation, and 15 (21.7%) had undergone other procedures. Results: Thirty-four patients (49.3%) were successfully weaned from ECMO, while the other 35 patients (50.7%) died on ECMO support. Among the 34 patients who were successfully weaned from ECMO, 21 patients (30.4%) eventually died before discharge from the hospital, resulting in 13 hospital survivors (18.8%). Multivariable analysis showed that the duration of pre-ECMO ventilation was a significant independent predictor of death (odds ratio [OR], 2.25; 95% confidence interval [CI], 1.29 to 3.90; p=0.004), whereas the concomitant use of continuous venovenous hemodialysis (CVVHD) was associated with improved survival (OR, 0.55; 95% CI, 0.31 to 0.97; p=0.038). Conclusion: Although the overall survival rate of patients treated with ECMO for postoperative ARDS was unfavorable, ECMO offered an invaluable opportunity for survival to patients who would not have been expected to survive using conventional therapy. CVVHD may be beneficial in improving the outcomes of such patients, whereas a prolonged duration of pre-ECMO ventilator support was associated with poor survival.
Changes in the Leydig cell from pre-puberty to adulthood were studied in Korean native cattle. Eight groups of male cattle aged 14, 17, 20, 25, 30, 35, 40 and 104 weeks (n=7 cattle per group) after birth were used. The purpose of this study was to obtain quantitative information on the Leydig cell of the Korean native cattle during postnatal development. Testes of cattle were fixed by perfusion using a fixative containing 2.5% glutaraldehyde in cacodylate buffer, processed and embedded in Epon-araldite. Using $1{\mu}m$ section stained with methylene blue-azure II, qualitative and quantitative (stereological) morphological studies were performed. The average diameter of seminiferous tubules gradually increased with age from 14 ($75.56{\mu}m$) to 104 weeks ($298.9{\mu}m$). The volume density of the seminiferous tubules increased with age from 54.2% at week 14 to 76.9% at week 104. The volume density of the interstitium represents 45.52% at week 14. This proportion progressively diminishes during development to reach a value of 23.14% at week 104. The volume density of Leydig cells decreased almost linearly from 14 (20.71%) to 104 weeks (5.28%). The absolute volume of Leydig cells per testis increased significantly from 14 to 104 weeks. The number of Leydig per testis have almost linearly increased from 14 to 104 weeks. The average volume of a Leydig cell reached maximum size by 104 weeks ($2553{\mu}m^3$). These data suggested development of Leydig cell can be classified as the fetal and immature adult Leydig cells (14~35 weeks), and the adult Leydig cells (40~104 weeks).
The purpose of this study was to evaluate Korean advance directives (K-AD) by examining the degree of adults' acceptance and reliability of the directive itself. Methods: Survey was performed with 181 adults aged 20 or older who were recruited from three regions. A questionnaire used to examine the participants' acceptance of their K-AD in terms of visual analogue scale score of complexity, difficulty, necessity, satisfaction, recommendation. Then, a retest was carried out by asking participants to write up a K-AD again to confirm the reliability of the directives. Results: On a scale of 100, the average acceptance score was 70 or above, which represents rather high level of acceptance in all five categories. The test-retest reliability kappa values ranged from 0.592 to 0.950, and the conformity degree was moderate or high. Regarding K-AD components such as values, treatment preference, proxy appointment, differences among age groups were observed in each component. Conclusion: The results of this study suggest that K-AD is a feasible instrument to analyze its acceptability and reliability for adult population. K-AD could be utilized to help people make their own decision on their end-of-life care. Further studies are needed to confirm this study results and promote widespread use of K-AD.
Purpose: The purpose of this study was to examine nurses' emotional responses and ethical attitudes towards elderly patients' Do-Not-Resuscitate (DNR) decision. Methods: Data were collected using a questionnaire which was filled out by 153 nurses who worked in nursing homes and general hospitals. Data were analyzed using real numbers, percentages, means, standard deviations and Pearson's correlation coefficients with SPSS 19.0 program. Results: The average score for ethical attitudes towards the DNR decision was 2.68 out of 4. Under the ethical attitudes category, the highest score was found with a statement that said 'Although they will not perform cardiopulmonary resuscitate (CPR), it is right to do their best with other treatments for DNR Patients'. Items regarding emotional responses to the DNR decision, the average score was 2.36 out of 4. Among them, the highest score was achieved on 'I understand and sympathize'. No significant correlation was found between ethical attitudes and emotional responses in relation to patients' DNR decision (r=-0.12, P=0.13). Conclusion: Regarding elderly patients' DNR decision, nurses showed somewhat highly ethical attitudes and slightly positive emotional response. A follow-up study is needed to investigate variables that affect our results.

Objectives : The purpose of this study was to examine whether or not Postural Yinyang Correction of TMJ(Temporomandibular joint) using Standard intraoral appliance could decrease chronic low back pain. Methods : We reviewed the medical records of 40 patients with TMJ disorder aged from 30 to 70 years from 124 patients who were treated in chronic low back pain at Department of Acupuncture & Moxibustion of Korean Medicine Hospital of Dong-Eui University from November $1^{st}$, 2015 to June $5^{th}$, 2016. The patients were divided into 2 groups: Group A and Group B. In Group A, we treated the patients with acupuncture, sweet bee venom treatment and FCST(Functional Cerebrospinal Therapy) through Standard intraoral appliance from ABA(Accurate Balancing Appliance), Full body exercise therapy, and Upper cervical alignment balance therapy. In Group B, we treated the patients with acupuncture and sweet bee venom treatment. To estimate the effectiveness in controlling pain, we analyzed the Visual analog scale(VAS). To evaluate functional change of patients, we analyzed the Oswestry low back disability questionnaire(ODI). Results : In both groups, VAS and ODI decreased significantly. In the VAS, the result of Group A is significantly more effective than that of Group B. In the ODI, the result of Group A is statistically less effective compared to that of Group B, but not significantly. Conclusions : According to the results, Postural Yinyang Correction of TMJ using Standard intraoral appliance may be effective treatment for low back pain, but the further researches are needed.
The purpose of this investigation was to determine the effect of feeding dried mackerel as a means of increasing the intake of these n-3 polyunsaturated fatty acids on fatty acid compositions in liver and nervous tissue. Twenty male mice aged at 4 weeks were fed on the control (5% palm oil, control group) and 5% dried mackerel diets (mackerel group) for four weeks. In fatty acid compositions of liver and cortex, levels of total n-3 fatty acid, specially docosahexaenoic (22:6n-3, DHA) and eicosapentaenoic (20:5n-3, EPA) acids, were increased in the mackerel group compared to the control group, while docosapentaenoic acid (22:5n-6, DPAn-6) levels were decreased (p<0.05). In cerebellum and retina, levels of DHA were not significantly different between the control and mackerel groups, but levels of total n-6 fatty acids and arachidonic acid (20:4n-6, AA) were decreased in the mackerel group. These results indicated that intake of 5% dried mackerel increased levels of n-3 polyunsaturated fatty acids in cortex. Thus, we will investigate the relationship between brain function and cortex fatty acid compositions following intake of mackerel by assessing discrimination leaning ability.
This study was performed to investigate the increase of S-allylcysteine content, a biomarker of black garlic, during its aging period, as well as the serum lipid-lowering effects of black garlic extract in high fat diet fed rats. The highest content of S-allylcysteine was observed on the 15th day of the aging period. Sensory evaluation was also estimated to be extremely good on the 15th day of the aging period. High fat diet rats with induced hyperlipidemia were fed diets containing black garlic extract of low, medium, and high doses for 6 weeks. No significant difference in body weight gain and food efficiency was observed between normal, placebo and black garlic fed groups. Liver weight was significantly higher in black garlic fed groups than in the normal group. Total serum cholesterol and triglyceride were significantly lower in low, medium, and high dose groups than in the normal group. Also, HDL-cholesterol was significantly higher and LDL-cholesterol was significantly lower in black garlic diet fed groups than in the normal group. Hepatic levels including total lipid and cholesterol were especially decreased in the black garlic diet fed group than in the placebo group. These results suggest that black garlic intake reduces the levels of serum and hepatic cholesterol in high fat diet fed rats. In conclusion, black garlic has a potential to be used as a functional health food ingredient with beneficial effects on lowering cholesterol and triglyceride levels.
