PURPOSE: The aim of this study was to investigate the pathophysiologic role of serum E-selectin, vascular endothelial growth factor(VEGF)-induced cell adhesion mollecule in Kawasaki disease(KD) and to look for the evidence of direct relationship between the plasma levels of soluble E-selectin and the incidence of coronary artery lesion(CAL). METHODS: Changes in plasma levels of sE-selectin(n=98) over time were measured by enzyme-linked immunosorbent assay(ELISA) in 23 patients with acute KD and 25 age-matched febrile children. RESULTS: Compared with control values, the peak levels of plasma sE-selectin were significantly elevated(mean+/-S.E.:22.89+/-12.53 ng/mL vs 10.65+/-3.42 ng/mL, P=0.01) in KD. 5 patients with CAL, plasma sE-selectin levels before treatment were higher than in 18 patients without CAL(mean+/-S.E.:39.43+/-15.08 ng/mL and 19.00+/-8.32 ng/mL, respectively; P=0.01). Plasma sE-selectin declined rapidly in the majority of KD patients regardless of the presence of CAL. Plasma sE-selectin levels after treatment and convalesent period were similar in KD patients with and without CAL. The plasma levels sE-selectin were correlated with those of white blood cell count(r=0.299, P<0.05), CRP(r=0.430, P<0.05), serum albumin(r=-0.483, P<0.05), serum protein(r=-0.502, P<0.05) and hemoglobin(r=-0.372, P<0.05) not with those of ESR, platelet, or duration of fever. There were significant differences in the initial level of serum sE-selectin between KD with and without CAL(mean+/-S.E.:39.44+/-15.08 ng/mL vs. 19.00+/-17.18 ng/mL) in multivariated linear tests. CONCLUSION: Plasma sE-selectin levels were significantly higher in KD than in other febrile illness. Higher plamsa levels of sE-selectin may have potential as a predictor of CAL in patients with KD.

Osteoarthritis (OA) is the most common arthritis which leads to chronic disability. Because patients usually present at medical care at an advanced stage of disease, research on pathogenesis of OA using human subjects is difficult. Therefore, animal models of OA are used extensively in search of pathogenesis of degenerative joint disease and in search of potential disease modifying anti-OA drugs. For induction of OA, chemical and surgical methods have been employed widely due to several advantages, such as faster onset of disease and reproducible induction of arthritic change. Intra-articular injection of a chemical such as monosodium iodoacetate or collagenase can cause the degeneration of cartilage and the development of osteoarthritis by inhibition of the activity of glyceraldehyde-3-phosphate dehydrogenase in chondrocytes or by induction of synovial inflammation and degeneration of supporting structure and resultant instability, respectively. Surgical induction involves destabilizing the knee joint by transection of the cranial cruciate ligament, collateral ligaments, or meniscotibial ligament with or without removing all or part of the meniscus. Surgical models are used not only in small animals but also in larger animals such as rabbits, sheep and dogs. Additionally, genetically modified mouse models offer opportunities to look into a specific role of a molecule or signaling pathway in the joint degradation. On the other hand, whether these models, chemically or surgically induced, or genetically modified, properly represent human OA is a critical question. Except for a limited number of cases, most human OA develops insidiously over decades without significant antecedent knee injury. In this sense, spontaneous model which develops in mice and guinea pigs might more closely resemble human OA. In this review, widely used animal models of OA are presented, focusing on the methods of its induction, their use for determining the pathophysiology of OA, and advantages and limitations of its use.

BACKGROUND & PURPOSE: The ocular torsion (OT) and tilt of the subjective visual vertical (SVV) are sensitive brainstem signs and helps us to localize lesion. We calibrated the degree of OT, SVV tilt and head tilt to investigate their characteristics and temporal profiles in patients with brainstem lesion. METHODS: We selected 15 patients with acute brainstem stroke. We took serial fundus photographs and body pictures in upright position at various times after the stroke. We also determined the deviations of patient's SVV. The data measurement for this investigation ranged from day 2 to day 47. RESULTS: Eight of ten patients with lateral medullay infarction showed ipsiversive tilt of SVV and OT. Among four patients with pontine infarction, one showed ipsiversive tilt and three contraversive. One patient with midbrain hemorrhage showed cotraversive tilt. The resolution of OT and the tilt of SVV in medullary lesions occurred over the periods ranging from 7 days to more than 47 days and was slower in patients with upper brainstem lesion than lower brainstem lesion. The directions of head tilt in our patients, especially with medullary lesions, were rather different from the previous reports. CONCLUSION: The vestibular dysfunction by the brainstem lesions disturbs the eye and head stabilization and also distorts the perception of the subjective vertical in space. The direction of OT and the tilt of SVV is ipsiversive in lower brainstem lesion and contraversive in upper brainstem lesion. But head tilt is contraversive in most lower brainstem lesion as well as upper brainstem lesion. Large-grouped study for the direction of head tilt is thought to be needed. These signs are compensated in the course of clinical recovery.

The uterus with rudimentary horn occurs as a result of a lack of development during fetal life of the middle and lower parts of one of the Miillerian ducts, in which there is a failure of fusion of the two ducts, The incidence of this uterine anomaly is rare. Many cases of rudimentary uterine horn are not discovered since they do not become involved in a pregnancy, and thus remain symptomless and uncomplicated, and the diagnosis usually being made only with pregnancy with rupture. In this presentation, we describe a case of diagnosis and management of unruptured non-communicating rudimentary uterine horn pregnancy at the third trimester. The patient diagnosed by ultrasonography and MRI, was hospitalized for further evaluation and delivery under the impression of unruptured non-communicating rudimentary horn pregnancy. A living male infant weighing 1,930 gm was delivered by cesarean section at 33+l weeks due to impending preterm labor. Some articles concerned this subject were reviewed briefly to discuss relevant method of diagnosis, treatment, and clinical characteristics.

OBJECTIVES: This study aims to identify dietary factors related to metabolic syndrome in middle aged Korean men who were participants in the Fourth Korea National Health and Nutrition Examination Survey(KNHANES IV) in 2007. METHODS: The study targeted 361 of the 709 men aged between 40 and 64 years for a final analysis; the other 348 surveys had incomplete data which did not allow for the determination of metabolic syndrome. The definition of metabolic syndrome was based on the National Cholesterol Education Program Adult Treatment Panel III(NCEP ATP III). RESULTS: There were significant differences in the metabolic syndrome of middle-aged men according to age, smoking pack-years, and number of resturant meals per week. Dietary factors such as vitamins, riboflavin, natrium, carbohydrate, protein and lipid intakes were not significant. CONCLUSIONS: It was verified that metabolic syndrome in middle-aged men is related to age, smoking pack-years and number of resturant meals per week. Dietary factors were not significantly related. However, further detailed studies in this area are needed.

BACKGROUND: Chronic cough is a common clinical problem to which various etiologies are attributable; postnasal drip, asthma, gastroesophageal reflux (GER) and chronic bronchitis, However, in some cases, no particular etiology can be confirmed. OBJECTIVE: This study was aimed to evaluate cough sensitivity and the clinical manifestations of patients with idiopathic chronic cough. MATERIALS AND METHODS: We recruited 70 non-smoking patients who had been coughing for more than 3 weeks without any history, symptoms or signs of rhinitis, sinusitis, typical asthma, GER or recent upper respiratory infection episodes. Nineteen healthy controls were also enrolled. Bronchial provocation tests with methacholine, capsaicin and distilled water (DW) were performed. RESULTS: Thirteen patients were positive to rnethacholine test (PC20 < 25mg/ml) and defined as cough variant asthma. The others are classified into idiopathic chronic cough. By capsaicin and DW challenge tests, idiopathic cough patients could be divided into two groups, i.e., increased cough sensitivity (ICS) and normal cough sensitivity (NCS) groups. DW- induced cough counts were negatively correlated with C7 (lowest capsaicin concentration inducing continuous 7 or more coughs) (r=-0.739, p<0.001). No difference was found in clinical features such as age, sex, atopy, or peripheral eosinophil counts between these two groups but cough counts per cough burst were significantly higher in the ICS group. CONCLUSION: The heterogeneity in cough sensitivity of idiopathic chronic cough patients may refiect different pathophysiologic mechanisms. It is unclear whether patients with NCS merely have habitual or psychogenic cough or not. These suggest that different therapentic strategies should be established on idiopathic chronic cough patients according to cough sensitivity.

PURPOSE: Among the many factors associated with acute intestinal mucosal infection, numerous studies have proposed the usefulness of fecal calprotectin. The aim of this study was to evaluate the usefulness of fecal calprotectin in the diagnosis of necrotizing enterocolitis (NEC). METHODS: We collected 154 stool samples from 16 very low birth weight and premature newborns at the Konyang University Hospital neonatal intensive care unit or neonatal nursery. The stool samples were collected using the Calprest device, and the fecal calprotectin level was measured with the BUHLMANN Calprotectin enzyme-linked immunosorbent assay kit. RESULTS: Fecal calprotectin levels were significantly higher in the NEC group than in the non-NEC group (P=0.02). There was a significant positive linear relationship between the fecal calprotectin level and number of days after birth (P=0.00) in the gestational age <26 weeks group. There was a significant negative linear relationship between the calprotectin level and number of days after birth (P=0.03) in the gestational age > or =26 weeks and <30 weeks group. There was no difference in the calprotectin levels according to the type and method of feeding between the NEC and non-NEC groups. CONCLUSION: Fecal calprotectin levels were significantly increased in premature infants with NEC. The fecal calprotectin test is a noninvasive, easy, and useful tool for the diagnosis of NEC.
