This study was conducted to evaluate the relationship between change in obesity indices and change in serum lipids in adult male workers. Two-hundred-eight adult male workers of an industry in Taegu city were followed-up from 1991 to 1995. Height, weight, circumferences of hip and waist, blood pressure were measured and serum lipids were analysed. Data on life style were obtained using self-administered questionnaires. Mean differences of anthropometric measurements between 1991 and 1995 were as follows; 1.63kg in weight, 3.61cm in waist circumferences, 4.23cm in hip circumferences, 0.52kg/m2 in BMI and -0.021 in WHR. Those of lipids were as follows; 15.09mg/dl in total cholesterol, 20.43mg/dl in triglyceride, 9.40mg/dl in HDL-cholesterol, 2.87 in MI-index(p<0.01) and 350mg/dl in LDL-cholesterol. The changed value of BMI and Katsura index were strongly correlated with that of total cholesterol(r=0.174, p<0.05), the changed value of BMI correlated with that of triglyceride(r=0.374, p<0.01) and the changed value of weight correlated with that of MI index(r=-0.173, p<0.05). The changed value of WHR was significantly correlated with that of total cholesterol(r=0.162, p<0.05), however, was not significantly correlated with HDL-cholesterol, LDL-cholesterol, triglyceride and MI index. The changed value of weight, BMI and Katsura index were correlated with that of triglyceride(r=0.262, p<0.01; r=0.267, p<0.01; r=0.258, p<0.01) and the changed value of MI index(r=-0.143, p<0.05; r=-0.158; r=-0.144, p<0.01), adjusting the pattern of change in life style. The changed values of HDL-cholesterol and MI index between 1991 and 1995 in low WHR group were significantly higher than those in high WHR group(p<0.05, p<0.01), adjusting the baseline value of them. Similar pattern was observed when considering Katsura index. When stratifying by BMI value of 1991, in low BMI group, the changed value of HDL-cholesterol and MI index showed the same pattern as above, however the of triglyceride was statistically higher in obese group than in non obese group(p<0.05). In conclusion BMI might be a better indicator to predict serum lipids change than other obesity indices.

BACKGROUND: Purinergic and cholinergic agonists elicit negative-inotropic and chronotropic effects, anticip-ating their protective action from the damage of overloaded myocardium. However, the actions of the agents during the ischemic insults are not yet clearly informed. The aim of this study was to investigate the role of the purinergic and cholinergic agonists on the simulated ischemic myocardium of the rat atrial fiber preparations. METHOD: Various action potential parameters (maximum diastolic potential MDP;action potential amplitude APA;velocity of phase 0 depolarization dV/dtmax;action potential duration APD90) were measured and compared in electrically paced, normal (NPSS) and modified physiological salt solution (MPSS) superfused rat atrial fibers in vitro, using conventional 3M-KCl microelectrode technique. Ischemia-simulated modified physiologic solutions were prepared by changing the solution's composition. RESULTS: Hypoxic-and/or hyperkalemic-MPSS decreased all the action potential (AP) variables. However, no significant changes of the AP variables were developed by the acidic-or glucose-free MPSS. Adenosine (Ado) and cyclopentyladenosine (CPA) only decreased the APD90 in a dose-dependent manner. Acetylcholine (Ach) and carbachol (Cch) hyperpolarized the MDP, increased the dV/dtmax with certain doses, and decreased the APD90 dose-depen-dently. The potency for APD90-decrease was greater in order, CPA>Cch>Ach>Ado. Ado and CPA did not affect the hypoxic, hypokalemic MPSS-induced dV/dtmax-decrease. On the other hand, Ach and Cch sig-nificantly inhibited the dV/dtmax-decrease by the hypoxic hypokalemic-MPSS. Ado, CPA, Ach and Cch sig-nificantly augmented the hypoxic, hypokalemic MPSS-induced APD90-decrease. The inhibition by the Ach and Cch on the MPSS-induced dV/dtmax-decrease was not affected by DPCPX, but atropine significantly attenuated the inhibition by the cholinergic agonists. DPCPX inhibited the augmentation by the Ado and CPA on the MPSS induced APD90-decrease, and atropine inhibited the effect of the cholinergic agonists. CONCLUSION: Both purinergic and cholinergic agonists not only shorten the AP duration by themselves but also enhance the AP-shortening effect elicited by the ischemia, and therefore, it is inferred that both agonists prevent further tissue damage from the ischemic insults.

BACKGROUND: To investigate the role of alpha-adrenergic receptors in the development of delayed afterdepolarization, the effect of alpha-adrenoceptor stimulation and blockade on ouabain induced delayed afterdepolarization(DDAD) was examined in rabbit heart Purkinje fibers. METHODS: Purkinje fibers, taken from adult rabbit(1.8 - 2.0kg) heart anesthetized with penobarbital, were mounted in a Luicite chamber and superfused with Tyrode's solution. The transmembrane potentials were measured by the conventional microelectrode technique while the fibers were being stimulated with rectangular pulses of 50% above threshold voltage. The delayed afterdepolarizations were induced by overdrive excitation in the presence of ouabain. RESULTS: Delayed afterdepolarizations were not observed during superfusion of the control Tyrode's solution containing propranolol(5x10(-7)M). However, the addition of ouabain in the presence of propranolol elicited DADs which were dose-, time- and drive cycle length- dependent. Phenylephrine(PE ; 10(-7)M), and alpha-adrenoceptor agonist, potentiated the ouabain-induced DAD during the initial superfusion(for 10 or 20 min) of the test Tyrode's solution. However, it was followed by attenuating-effects after a superfusion time of 50 to 60 min. Both effects showed ouabain dose-dependence. Ouabain(2x10(-7)M), in the presence of propranolol, depolarized the maximum diastolic potential and shortened the action potential duration, and the addition of PE(10(-7)M) did not affect the characteristics of action potential except a decrease in velocity of phase 0 depolarization. Prazosin, an alpha1-adrenoceptor antagonist, inhibited the PE's enhancing effects of ouabaininduced DDAD at 20 min superfusion, but did not affect the attenuating-effects of PE at 60 min superfusion. On the other hand, yohimbine, an alpha2-adrenoceptor antagonist, did not affect the PE's DAD potentiating-effects at 20 min superfusion, but inhibited the attenunating-effects of PE at 60 min superfusion. CONCLUSION: It is inferred that alpha-adrenergic stimulation induce delayed afterdepolarization and triggered activity in the rabbits, being responsible for the arrhythmia development, and the effects are mainly due to the action of alpha1-subtpe adrenoceptor stimulation.

Purpose: To analyze the repeatability of manual measurement of foveal avascular zone (FAZ) area in an optical coherence tomography angiography (OCTA) image in high myopia. Methods: This study comprised patients with high myopia and controls. Two consecutive FAZ areas of the superficial and deep capillary plexus were obtained using OCTA. The intraclass correlation coefficient (ICC) and coefficient of variation (CV) were assessed, and univariate and multivariate generalized linear mixed models were conducted to identify factors related to repeatability. Results: Thirty eyes with high myopia and 34 eyes of healthy subjects were included in the study. The mean age in high myopia and control subjects was 55.5 and 60.8 years, respectively, the mean spherical equivalent was −9.98 and −0.55 diopters, and the mean axial length was 28.0 and 23.9 mm. The ICCs of FAZ area of the superficial capillary plexus (SCP) were 0.891 and 0.919, while the CVs were 8.8% and 8.5%. In measurement of the deep capillary plexus, the ICCs were 0.788 and 0.907, while the CVs were 11.2% and 11.0%, which were acceptable but exhibited lower repeatability than those of SCP. Multivariate analyses showed that older age (p = 0.030) and greater axial length (p = 0.005) were significantly associated with lower repeatability of SCP FAZ area measurements. In addition, greater axial length (p = 0.044) was a significant factor for lower repeatability of deep capillary plexus FAZ area measurements. Conclusions Manual measurement of FAZ area using OCTA exhibited relatively good repeatability for high myopia. Age and axial length affected repeatability and should be considered when analyzing FAZ areas in high myopia patients.

OBJECTIVE: The aim of this study is to assess the correlation of progesterone challenge test (PCT) and endometrial thickness as a primary screening test for endometrial pathology in postmenopausal women prior to hormonal replacement therapy (HRT). METHODS: 92 postmenopausal women were measured serum estradiol (E2) level, endometrial thickness by transvaginal ultrasonography, and followed by PCT before HRT. And we compared the results of PCT with endometrial thickness and E2 levels. RESULTS: Women with a positive result of PCT in 32% of case and 75.9% of positive test showed endometrial thickness 4 mm or more. However 60.3% of negative test showed endometrial thickness 4 mm or more. This resulted in a PPV=76%, NPV=40%, sensitivity=37%, and specificity=78%. Mean serum E2 was significantly higher in patient with positive PCT but serum E2 showed no positive correlation with endometrial thichness (CI 95%, P Biopsy ; Estradiol ; Female ; Humans ; Mass Screening ; Menopause ; Pathology ; Progesterone* ; Ultrasonography

Fetal alcohol syndrome can be suspected in infants born to mothers with a prenatal history of alcohol abuse if the child exhibits characteristic facial features, together with intrauterine growth retardation, multiple neurological abnormalities, and multiorgan defects. If only a few of the above criteria are satisfied, the term fetal alcohol effects is used. We experienced a neonate who presented with hydrocephalus, low birth weight, seizure, right renal agenesis, characteristic facial features and a maternal history of alcohol abuse, and diagnosed him as fetal alcohol syndrome(FAS), with accompanying meconium aspiration syndrome, and persistent pulmonary hypertension of the newborn. There is no definite cure for FAS, but it can be prevented by maternal abstinence from drinking; thus maternal education, understanding and early diagnosis of those affected are of importance.

Renal vein thrombosis (RVT) is mostly related with other causes. The underlying conditions of RVT were nephrotic syndrome, trauma, cancer, anatomical anomalies, and other hypercoagulable status. Especially hypercoagulable status was rarely caused by obesity. We diagnosed renal vein thrombosis from an obese patient with hypertriglyceridemia. A male patient visited the Seoul National University Hospital for evaluating the reason of his flank pain. The pain started from two weeks ago, He had regarded flank pain as his obesity status (his weight was 84 kg and Body mass index was 29.41 kg/m2). So he had lost his weight by over-sweating one day before. At initial examination, his blood pressure was 128/75 mmHg, pulse rate was 72/min, respiration rate was 20/min and body temperature was 36.2degrees C. Blood chemistries revealed total cholesterol 218 mg/dL, Blood urea nitrogen/creatinine 12/1.3 mg/dL Urinalysis showed specific gravity 1.015, pH 5.5, protein 2+, blood 2+, RBC/WBC 1-4/<1 HPF on microscopic examination. Twenty-four hour collection of the urine showed protein 329 mg/day, creatinine clearance 90 mL/min. Renal vein thrombosis was visualized on the renal computed tomography and pulmonary embolism on the lung scan. Then, anticoagulant therapy was started after coagulation related tests. However, no abnormality of coagulation tests was detected. The evidence of malignancy was not detected either. After anticoagulation therapy, the pain was subsided. The only underlying cause for his hypercoagulability was considered obese status. Unfortunately we had not checked the triglyceride, initially. So we could not prioritize the reason of renal vein thrombosis into hypertriyglyceridemia. We considered that his obese status and subsequent hypertriyglyceridemia might be one of the causes of renal vein thrombosis.

PURPOSE: This study was performed retrospectively and to compare the clinical outcomes of the surgical management using Antiglide plating and lateral plating for Danis-Weber type B isolated lateral malleolar fractures. MATERIALS AND METHODS: Between March 2004 and March 2009, 92 patients were followed up for more than 6 months after surgical treatment. 49 patients were treated with Antiglide plating, whereas the remaining 43 patients underwent lateral plating. The results of the two groups were analyzed both radiographically and clinically using Ankle scoring system. RESULTS: Both groups were comparable for age, sex distribution, time to surgery, and operation time. Bone union was noted at average of 8 weeks in all fractures. The mean ankle score was similar in both groups (94% versus 93%). CONCLUSION: Antiglide plating for Danis-Weber type B isolated lateral malleolar fracture is one of the good methods which has some advantages such as early ankle motion, ambulation and smaller operative incision.

BACKGROUND: To evaluate the role of free fatty acids on the ischemic myocardium, influences of various free fatty acids upon transmembrane action potential and ATP-sensitive K+(KATP) channel activity were examined in the ventricular myocardium and single cardiac myocytes. METHODS: KATP channel activities were measured in the enzymatically (collagenase) isolated single rat ventricular cardiac myocytes by the method of the excised inside-out and the cell-attached patch clamp, and transmembrane action potentials were recorded using the conventional 3M-KCl microelectode techniques in the rat ventricular myocardium. RESULTS: Free fatty acids [FFAs; arachidonic acid (AA), linoleic acid (LA) and lysophosphatidylcholine (LPC)] reduced the KATP channel activity in a dose-dependent manner in the inside-out patch, and 50%-inhibition concentrations (IC50) were 88 +/- 11.2, 49 +/- 12.5, and 188 +/- 17.4 M respectively. Both frequency of channel opening and the mean open-burst duration were markedly decreased, but the amplitude of single channel currents were not changed by the FFAs. AA (50 micrometer) and LPC (50 micrometer) did not affect the dinitrophenol (DNP, 50 micrometer)-induced KATP channel activity, whereas LA (50 micrometer) had a tendency to reduce the activity. The channel inhibition effects by 10 micrometer AA in the inside-out patch were significantly augmented by diclofenac (10 micrometer), but was not changed by nordihydroguaiaretic acid. FFAs never stimulated KATP channel activity, even in the inside-out patch where KATP channel activity reduced in the presence of internal ATP (100 micrometer). Time for 90% repolarization (APD90) significantly increased during superfusion of the FFAs, to 22 (50 micrometer AA), 24 (50 micrometer LA), and 18 (50 micrometer LPC) % from those of the contol at the time of 10 min superfusion, but the other action potential characteristics were not changed by the FFAs. AA (10 micrometer) attenuated cromakalim (10 micrometer)-induced APD90 shortening effects. CONCLUSION: It was inferred that FFAs inhibit the KATP channel activity directly by themselves and/or indirectly by their metabolites in the rat ventricular cardiomyocytes, and therefore, duration of action potential lengthens to be a burden over the ischemic myocardium accounting for the injury of myocardium at the late stage of ischemia.
