This study was conducted to investigate instant coffee-mix intakes and its relations with anthropometric measurements, nutrient intake, and blood lipid in Gangneung and Samcheok residents. Coffee-mix is a mixture of instant coffee, sugar and coffee-creamer. It is a standardized convenience food in Korea. Recently, Koreans appear to consume too much of instant coffee-mix. The respondents of this study were 218 Koreans (Gangneung region 133, Samcheok region 85). The average age was 56.0 years (male), 57.5 years (female). They were divided into 2 groups, the instant coffee-mix drinkers and the non-drinkers. The nutrient intake and anthropometric measurements and their relations with coffee-mix intakes were analyzed (nutrient intakes were calculated by converting per 1,000 kcal and adjusted by age, region). As for male, body fat was significantly higher in coffee-mix drinkers (18.1 kg, 25.0%) than in nondrinkers (17.1 kg, 23.8%). In the case of females, serum triglyceride was significantly higher in coffee-mix drinkers (109.1 mg/dL) than in nondrinkers (102.9 mg/dL). Coffee-mix intakes and coffee-mix's contributions to energy were higher for participants from Samcheok (21.2 g, 4.7%) than those from Gangneung (16.6 g, 3.4%). In addition, for Samcheok, coffee-mix's contribution to energy was significantly higher in male (5.6%) than in female (4.2%). Coffee-mix intakes and energy contribution of coffee-mix were not significantly correlated with anthropometric measurements. Only HDL-cholestrol showed significantly negative correlation with coffee-mix's contributions to energy. Based on the above results, we conclude that usual instant coffee-mix intake may increase intakes of sugar and fat and exert negative effects on serum lipids. Therefore, it is needed to control too much instant coffee-mix intake in the dietary management of rural residents.

Ovarian mature cystic teratoma containing benign prostatic tissue is rare and only 11 cases have been reported in the literature to date. We report a case of mature cystic teratoma of the ovary containing prostatic tissue. A 23-year-old female patient came to our hospital complaining of irregular menstruation for 3 months. Her menarche had occurred when she was 13 years old. The patient showed no evidence of virilization nor of endocrinopathy. A goose-egg-sized mass was palpable in the left lower abdomen on physical examination. Ultrasonography revealed a cystic ovarian mass with internal echogenecity. Microscopic finding was consistent with that of usual mature cystic teratoma except for a 1.5 cm focus of prostatic and bladder tissues. Prostatic tissue demonstrated strong immunoreactivity for prostatic specific antigen (PSA), prostatic alkaline phosphatase (PAP) and cytokeratin 7. Basal cells of the prostate glands were positive for high molecular weight cytokeratin (34betaE12). Although ovarian mature cystic teratoma containing prostatic tissue has been reported as a rare occurrence, a careful examination with immunohistochemical staining may increase the detection of prostatic tissue in mature cystic teratoma of the ovary.

This study examined salty taste acuity and salty taste preference and sodium intake in relation to zinc nutritional status in 2 rural populations in Korea. And we also examined the main food contributors of their sodium intakes. We enrolled 218 adults (66 men and 152 women) from the Kangneung and Samcheok regions in Korea's Kangwon province in our study conducted from December 2011 to February 2012. Participants from each region were divided into 3 groups based on their serum zinc level (T1: lowest, T2: intermediate, T3: highest). We compared the salty taste acuity and preference, Na index (Dish Frequency Questionnaire for estimation of habitual sodium intake), blood pressure, and intakes of nutrients including sodium by 3 groups of serum zinc level. The results were as follows: a higher serum zinc level indicated a lower sodium intake and Na index (P < 0.05). The salty taste acuity was considerably higher for participants from the Kangneung region than those from the Samcheok region (P < 0.05). And the serum zinc level was significantly higher in participants from the Kangneung region than those from the Samcheok region (P < 0.05). We further divided the participants into 2 groups: those who consumed more zinc than the recommended intake (RI) and the others. We compared salty taste acuity and salty taste preference in the 2 groups. The salty taste threshold and palatable salty taste concentrations were lower for the group with a zinc intake above RI than for the group with zinc intake below the RI. However, the difference was not significant. This study confirms that taste function differs depending on zinc nutritional status. In future, it is required to a large-scale, long-term, prospective study on the correlation between zinc intake, serum zinc levels, and taste perception function and blood pressure.

PURPOSE: Experience of chest pain may be different in women from that of men and this discrepancy may cause misdiagnosis of angina contribute to mortality by this disease in women. The purpose of this study was to analyze the characteristics of chest pain and responses to the symptoms in women. METHOD: A content analysis was conducted with interviewed data obtained from women who underwent the treadmill test RESULT: Seven major categories were identified from this content analysis: attributes of chest pain; accompanied symptoms; precipitating factors; relief strategies; family support; communication with physicians; and effects of chest pain on their lives. Characteristics of pain were described as heaviness, tightness, heating sensation, tearing, and others. Duration and intensity of pain varied in a wide range. Radiating pain presented in 9 patients, and the locations of radiation were throat, neck, shoulder arm and fingers. Women tended not to respond actively to their chest pain, and didn't get appropriate support either from their family or from their physicians when they reported chest pain. CONCLUSION: Women express non-typical as well as typical patterns of pain when they experience chest pain. Clinicians have to consider the variability of symptoms when they assess women with suspicions of angina.

PURPOSE: N-(3-[18F]Fluoroporpy)-2beta- carbomethoxy-3beta-(4-iodophenyl) nortropane ([18F]FP-CIT) has been shown to be very useful for imaging the dopamine transporter. However, synthesis of this radiotracer is some what troublesome. In this study, we used a new method for the preparation of [18F]FP-CIT to increase radiochemical yield and effective specific activity. MATERIALS AND METHODS: [18F]FP-CIT was prepared by N-alkylation of nor-beta-CIT (2 mg) with 3-bromo-l-[18F]fluoropropane in the presence of Et3N (5-6 drops of DMF/CH3CN, 140 degree C, 20 min). 3-Bromo-l-[18F]fluoropropane was synthesized from 5 microliter of 3-bromo-l-trifluoromethanesulfonyloxypropane (3-bromopropyl -l-triflate) and nBu4N18F at 80 degree C. The final compound was purified by reverse phase HPLC and formulated in 13% ethanol in saline. RESULTS: 3-Bromo-l-[18F]fluoropropane was obtained from 3-bromopropyl-l-triflate and nBu4N18F in 77-80% yield. N-Alkylation of nor-beta-CIT with 3-bromo-l-[18F]fluoropropane was carried out at 140 degree C using acetonitrile containing a small volume of DMF as the solvents. The overall yield of [18F]FP-CIT was 5-10% (decay-corrected) with a radiochemical purity higher than 99% and effective specific activity higher than the one reported in the literature based on their HPLC data. The final [18F]FP-CIT solution had the optimal pH (7.0) and it was pyrogen-free. CONCLUSION:: In this study, 3-bromopropyl-l-triflate was used as the precursor for the [18F]fluorination reaction and new conditions were developed for purification of [18F]FP-CIT by HPLC. We established this new method for the preparation of [18F]FP-CIT, which gave high effective specific activity and relatively good yield.

We evaluated the in vivo kinetics, distribution, and pharmacology of N-(4-[F] fluorornethylbenzyl)spiperone ([F]FMBS), a newly developed derivative of spiperone, as a potentially more selective #radiotrar.er for the dopamine (DA) Dz receptors. Mice received 1.9-3.7 MBq (1.8-3.6 nmol/kg) of [F]FMBS by tail vein injectivn. The time course and regional distribution of the tracer in brain were assessed. Blocking studies were carried out by intravenously preinjecting DA Dp receptor blockers (spiperone, butaclamol) as well as drugs with high affinity for DA Dr lSCH 23390), DA transporter (GBR 12909), and serotonin Sp (5-HTz) (ketanserin) sites. After injection of the tracer, the radioactivity in striatum increased steadily over time, resulting in a striatal-to-cerebellar ratio of 4.8 at 120 min postinjection. By contrast, the radioactivity in cerebellum, frontal cortex, and remaining cortex washed out rapidly. Preinjection of unlabe1ed FMBS (1 rng/kg) and spiperone (1 mg/kg) reduced [F] FMBS striatal-to-cerebellar ratio by 41Zo and 80Ya, respectively. (+)-Butaclamol(1 mg/kg) blocked 80Yo of the striatal [F]FMBS binding, while (-)-butaclamol (1 rng/kg) did not. Preinjection of SCH 23390 (1 mg/kg) and GBR 12909 (5 mg/kg) had no significant effect. On [""F]FMBS binding. Ketanserin (1 mg/kg), a ligand for the 5-H1g receptors, did not cause significant inhibition either in striatum, in frontal cortex, or the remaining cortex. The results demonstrate that [F]FMEtS labels DA Dz receptors selectively in vivo in the mouse brain. It may hold promise as a selective radiotracer for studying DA Dz receptors in vivo by PET.

PURPOSE: This study was designed to evaluate diagnostic accuracy of serial electrocardiograms(ECG), myocardial band of creatinine phosphokinase(CK)(CK-MB/CK ratio) and two dimensional echocardiography(ECHO) for myocardial injury in patients with blunt chest trauma. METHODS: We prospectively investigated 54 patients(male : 38, female : 16, mean age : 41) with severe blunt chest trauma. Presence of myocardial injury was determined by increase(>0.1ug/L) of peak serum troponin T(TnT) concentration from serial mesurements. RESULTS: Among 54 patients with blunt chest trauma, 23 patients(43%) had increased peak TnT level which suggested of myocardial injury. Among 23 patients with increased TnT, abnormal ECG findings were found in 18(78%) and echocardiographic abnormalities were observed in 17(74%). Cardiovascular events in 9(39%) of 23 patients with increase Tnt. There was no cardiovascular events in patients with normal TnT. CONCLUSION: Significant proprotion of patients with blunt chest trauma had elevated TnT value which suggested of myocardial injury. We recommend echocardiagraphy and serial tracing of ECG to verify the clinical significance of elevated TnT in patients with blunt chest trauma.
