The present study was investigated on type 2 diabetics' actual status of anti-diabetic functional food intake by patients who came to oriental medicine clinics in Daejeon. The male was 37.3% and female was 62.7% of the subjects. The onset of the disease was most common in the age of 50's. Also 40% of the subjects have been suffering for more than 5 years. 35.7% of men, 53.2% for women had family history. Also 61.5% of the patients chose to carry out both diabetic therapy and exercise at the same time. 69.3% of the subjects have had experiences in anti-diabetic functional foods. Anti-diabetic functional foods used to surveyed people were bean, ginseng, and ginseng steamed red of which efficacies were already well known. Besides these foods, other foods such as loach, crucian carp were also used as anti-diabetic foods, but their benefits as anti-diabetic functional foods are not yet fully investigated. Subjects first knew about the therapy because friends or relatives recommended to them and most of them have used for 6 months to 1 year. However, 78.9% of subjects answered 'not so effective' in a question about satisfaction of anti-diabetic functional food. Although many of the patients have tried taking functional foods, they only use them for short period of time and they don't show prominent effect. Therefore these results suggest that in order to use scientifically studied functional foods, education about anti-diabetic functional foods should taken.

Background: Esophageal squamous cell carcinoma (ESCC) is a common cancer with poor prognosis. It has been hypothesized that Oct4 positive radioresistant stem cells may be responsible for tumor recurrence. Hence, we evaluated Oct4 expression in ESCC in pre-treatment, post neo-adjuvant residual and post-surgical recurrent tumours. Materials and Methods: Endoscopic mucosal biopsies were used to study Oct4 expression and the observations were correlated with histological tumor grades, patient data and clinical background. Results: All patients presented with dysphagia with male predominance and a wide age range. Majority of the patients had intake of mixed diet, history of alcohol and tobacco intake was documented in less than half of the patients. Oct 4 expression was significantly higher in poorly differentiated (PDSCC) and basaloid (BSCC) subtypes than the other better differentiated tumor morphology. Oct4 was also expressed by adjoining esophageal mucosa showing low grade dysplasia and basal cell hyperplasia (BCH). Biopsies in PDSCC and BSCC groups were more likely to show a positive band for Oct4 by polymerase chain reaction (PCR). Dysplasia and BCH mucosa also showed Oct4 positivity by PCR. All mucosal biopsies with normal morphology were negative for Oct4. Number of tissue samples showing Oct4 positivity by PCR was higher than that by the conventional immunohistochemistry (p>0.05). Oct4 expression pattern correlated only with tumor grading, not with other parameters including the clinical background or patient data. Conclusions: Our observations highlighted a possible role of Oct4 in identifying putative cancer stem cells in ESCC pathobiology and response to treatment. The implications are either in vivo existence of Oct4 positive putative cancer stem cells in ESCC or acquisition of cancer stem cell properties by tumor cells as a response to treatment given, resulting ultimately an uncontrolled cell proliferation and treatment failure.

Background Conscious sedation has been widely utilized in plastic surgery. However, inadequate research has been published evaluating adequate drug dosage and depth of sedation. In clinical practice, sedation is often inadequate or accompanied by complications when sedatives are administered according to body weight alone. The purpose of this study was to identify variables influencing the depth of sedation during conscious sedation for plastic surgery. Methods This prospective study evaluated 97 patients who underwent plastic surgical procedures under conscious sedation. Serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine, and glucose levels were measured. Midazolam and ketamine were administered intravenously according to a preset protocol. Bispectral index (BIS) recordings were obtained to evaluate the depth of sedation 4, 10, 15, and 20 minutes after midazolam administration. Associations between variables and the BIS were assessed using multiple regression analysis. Results Alcohol intake and female sex were positively associated with the mean BIS (P<0.01). Age was negatively associated with the mean BIS (P<0.01). Body mass index (P=0.263), creatinine clearance (P=0.832), smoking history (P=0.398), glucose (P=0.718), AST (P=0.729), and ALT (P=0.423) were not associated with the BIS. Conclusions Older patients tended to have a greater depth of sedation, whereas females and patients with greater alcohol intake had a shallower depth of sedation. Thus, precise dose adjustments of sedatives, accounting for not only weight but also age, sex, and alcohol consumption, are required to achieve safe, effective, and predictable conscious sedation.

A 5-year-old Thoroughbred race horse was presented to Busan Korea Racing Authority equine hospital with a 3-year history of a slow-growing left rostral maxillary mass. The location and progressive growth of the mass eventually resulted in poor food prehension, quidding and mouth bit placement. The mass was solitary and hard, and covered by normal smooth oral mucosa. Radiographic examination of the maxillae showed a flocculated and mixed radiolucent lesion protruding outward and displacing the 202 and 203 teeth caudally. The 202 tooth was in normal size and the 203 tooth was hypoplastic on radiography. Under general anesthesia, a partial surgical resection of the mass was performed to minimize functional loss and facilitate prompt return to track. After surgery, there was improvement in food intake, mouth bit placement, and cosmetic appearance. Histopathological examination determined the resected maxillay mass to be an ossifying fibroma. However, there was continued growth of remnant mass in the maxilla. Equine ossifying fibroma is a rare condition and primarily affects the rostral mandible, and less commonly, the maxillae. In this case, the lesion was slow-growing, and caused cosmetic and functional impairments, including poor food intake and reduced trainability. Surgical resection was performed, but the effect of treatment was limited due to advanced size / stage of the tumor. Early dental care is suggested for horse owners to prevent belated identification and improve successful treatment of oral disorders like ossifying fibroma.

Objective: The purpose of this study was to identify dietary factors related to infertility in Korean women through a case-control study. Methods: The case group was composed of 236 women who had been diagnosed as infertility in hospital. The control group of 181 healthy women with children were recruited from local immunization centers. Socio-economic status, medical history, dietary intakes using food frequency questionnaire and stress were surveyed by interview. Anthropometric measurements were made and the causes of infertility were identified through medical records. Fasting blood samples were taken from subgroup of the subjects. Results: The mean age of infertile and control groups was 31.1 and 32.4 years, respectively and the difference was statistically significant. The mean Body Mass Index of infertile women was not significantly different from control women, however, Waist/ Hip Ratio and Triceps Skinfolds Thickness were significantly lower in infertile women than in control women. The dietary intake status was generally satisfactory in both groups. The intakes of energy, protein, fat, carbohydrate, retinol, vitamin B2 and niacin were lower in infertile women than in control women. The infertile women also showed lower intakes of animal foods. No differences were found between two groups in serum concentrations of albumin, hemoglobin, Fe, TIBC, total cholesterol, HDL-cholesterol, LDL-cholesterol, triglyceride, C3, IgA, IL-2, however, infertile women showed higher levels of Zn and IgG. The stress score was higher in infertile women. Conclusions: From the results of this study, dietary factors and nutritional status do not seem to be directly related to infertility. However, the intertile women have lower nutrient intake and lower body fat content than control women. Further researches are needed according to the causes of infertility for long term to establish the relationship between dietary factors and infertility.

Background: Hypertension is a major contributor to the global disease burden of cardiovascular and cerebrovascular disease. The aim of this study was to determine demographic and clinical factors associated with adherence to antihypertensive medication. Methods: From August 2012 to February 2015, we recruited 1,523 Korean patients with hypertension who visited family physicians. The study was conducted in 24 facilities located in urban and metropolitan areas. Of these facilities, two were primary care clinics and 22 were level 2 or 3 hospitals. Adherence was assessed using the pill count method; a cut-off value of 80% was used as the criterion for good adherence. Sociodemographic and lifestyle factors were compared between the adherent and nonadherent groups using the chi-square test for categorical variables and t-test for continuous variables. Binary logistic regression analysis was performed with medication adherence as the outcome variable. Results: Of the 1,523 patients, 1,245 (81.7%) showed good adherence to antihypertensive medication. In the multivariate logistic analysis, age ${\geq}65$ years, exercise, treatment in a metropolitan-located hospital, being on ${\geq}2$ classes of antihypertensive medication and concomitant medication for diabetes, and a family history of hypertension or cardiovascular diseases were associated with good adherence. Patients who had a habit of high salt intake were less adherent to medication. Conclusion: Multiple classes of antihypertensive medications, concomitant medication, and exercise were associated with good adherence to antihypertensive medication, and high salt intake was associated with poor adherence to antihypertensive medication. These factors should be considered to improve hypertension control.

Purpose: In acute acetaminophen poisoning, the administration of N-acetylcysteine (NAC) can effectively treat the main complications, such as kidney injury and liver failure. In the current situation, measurements of the acetaminophen concentration are not checked in the usual medical facilities. Therefore, this study examined the factors of determining the administration of NAC in addition to the stated amount of intake. Methods: The medical records of patients who visited Ajou University Hospital emergency center with acetaminophen poisoning from January 2015 to December 2019 were reviewed retrospectively. One hundred and seventy-nine patients were initially included. Among these patients, 82 patients were finally selected according to the inclusion criteria in the study. The inclusion criteria were as follows: patients who were 15 years of age or older; those whose ingested dose, ingested time, and body weight were clearly identified; and patients whose acetaminophen sampling time was within 24 hours. Patients were divided into two groups: NAC administered vs. non-NAC administered. The following variables were compared in these two groups: ingested dose, ingested dose per body weight, hospital arrival time after ingestion, suicide attempt history, psychiatric disease history, classification of toxic/non-toxic groups, duration of hospitalization, and laboratory results. Results: Univariate analysis revealed the ingested dose per body weight, hospital arrival time after ingestion, suicide attempt history, and psychiatric disease history to be the determining factors in administering NAC. Logistic regression analysis confirmed that the ingested dose per body weight was the only significant factor leading to an NAC treatment decision. (Odds ratio=1.039, 95% Confidential interval=1.009-1.070, p=0.009) Conclusion: The ingested dose per body weight was the only determining factor for administering NAC in patients with acute acetaminophen poisoning. On the other hand, additional criteria or indicators for the NAC administration decision will be necessary considering the inaccuracy of the ingested dose per body weight and the efficiency of NAC administration.

Objectives: A community-based, cross-sectional survey was conducted to determine theprevalence of osteoporosis and to evaluate the effects of body composition, health behaviors and reproductive history on bone density in postmenopausal women. Methods: The study subjects were 362 postmenopausal women, aged 45 years old or over, who were invited to the hospital. Information on their socio-demographic characteristics and the potential risk factors such as their past medical history, smoking, alcohol intake, exercise, diet and menstrual/reproductive histories were collected by trained interviewers. Weight, height, the body mass index ($kg/m^{2}$), and body composition variables were measured. Bone mineral density of the lumbar spine was measured by dual energy X-ray absorptiometry (DXA). Results: The prevalence of osteoporosis was 30.6% in the $45{\sim}64$ years old women, 52.5% in the elderly women aged $65{\sim}74$, and 68.7% in the women aged 75 years or over. After adjustment for the effect of potential covariates, those women in the highest 25% (4th quartile) of the lean body mass are less likely to have osteoporosis (aOR=0.31, 95% CI=0.12-0.76), compared with the lowest quartile group. More parity also had significantly detrimental effects on osteoporosis. Conclusions: These findings suggest that the prevalence of osteoporosis in postmenopausal women increased with age from 46.3% of those aged 45-64 to 68.7% for those aged 75 and over. Lean body mass and parity appeared significant contributor to bone mineral density in postmenopausal women in this population.

The effects of dietary calcium levels on the blood pressure and calcium metabolism were investigated. Nine normotensive female college students having hypertention family history were participated in 4-week dietary expeiments. They were provided with either high Ca diet (HCa, average 797mg/day) or low Ca diet(LCa, average 225mg/day) during two weeks, each, consecutively. Sodium amounts of the body diets were 3566~4022mg/day, which were ordinary sodium intake levels in Korea. After the HCa, systolic blood pressures(SBR) in both seated and isogrip-seated postitions were decreased by about 2.5mgHg, comparing with those after the LCa(p<.05). Diastoilc blood pressures(DBP) were not changed by dietary calcium levels. Serum total Ca, ionized Ca, Mg and P levels and Ca/Mg ratio were not different between the HCa and the LCa. Serum parathyroid hormone(PTH) levels were similar between two diets, but individually in seven of nine subjects, the slightly lower values of PTH were observed after the HCa than after the LCa. Urinary excretion of Ca(p<.01), Mg(p<.05) and P(p<.1) were increased after the HCa comparing with the LCa, but Ca/Mg ratio were not different between the two diets. SBP was in positive correlations with boty urinary excretion of Ca(supine, r=.7356, p<.05) and urinary Ca/Mg ratio(isogrip-seated, r=.7483, p<.05). SBP was also negatively correlated with serum P level(supine, r=-.6930, p<.05) and DBP was in negative correlation with urinary P excretion(seated, r=-.8586, p<.01). Serum total and ionized Ca, Mg, Ca/Mg ratio were not significantly correlated with blood pressures.
