A 7-year-old castrated male Korean Shorthair cat was referred with lethargy and anorexia. Laboratory examination revealed moderate degenerative changes of peripheral neutrophils on blood smear examination and decreased levels of free and total thyroxine ($T_4$) as well as bacterial growth on blood culture. Molecular analyses of the 16S ribosomal RNA gene and heat shock protein 60 gene confirmed the bacterium as Enterobacter cloacae. A minimal inhibitory concentration test showed multidrug resistance of the bacterium against 16 antibiotics. Polymerase chain reaction (PCR) and subsequent sequencing specifically for $bla_{TEM}$, $bla_{SHV}$, $bla_{CTX-M}$, and plasmid-mediated ampC genes revealed positive results to $bla_{TEM-1}$, $bla_{CTX-M-15}$, and plasmid-mediated $bla_{ACT-1}$ genes, indicating that the isolated bacterium contains plasmids containing genes encoding extended-spectrum beta-lactamase and plasmid-mediated ampC beta-lactamase. After 1 month of treatment with antibiotics and levothyroxine, the cat's condition improved; both the thyroid function test and the blood culture showed no abnormalities. This is the first report of community-acquired multidrug-resistant E. cloacae-induced euthyroid sick syndrome in a cat. By the prompt diagnostic procedures and properly selected antibiotic therapy, the cat was recovered from the multidrug-resistant bacterium-induced septicaemia.

The goal of this study was to describe dental consultation of pediatric inpatients to the department of pediatric dentistry at Yonsei University Severance Hospital. 391 dental consultations at Yonsei University Severance Hospital referred to pediatric dentistry in the year 2012 were included in this study. Consultations were categorized according to patients' gender, age, chief complaint, referred department and diagnosis. 288 patients (166 males and 122 females) with an average age of 5.9 were referred to the Department of Pediatric Dentistry. 129 cases (33.1%) from Department of Rehabilitation Medicine, 80 cases (20.5%) from Pediatric Hematology- Oncology, 51 cases (13.0%) from Pediatric Cardiology, and 44 cases (11.3%) from Pediatric Neurology. Chief complaints were ranked from oral examination (39.7%), dental caries (14.0%), pre-operative evaluation (12.8%) and others (33.5%); including oral pain, trauma, tooth mobility, orthodontic treatment, self-injury, fabrication of obturator and etc. Dental consultations should be encouraged as dental care and treatment could affect the control of systemic diseases of admitted patients. Pediatric inpatients have been referred to pediatric dentistry for not only comprehensive oral exam but also various chief complaints. The most frequent dental diagnosis made and treatment performed were dental caries and non-invasive/preventive care respectively.

Purpose: Intrauterine growth retardation (IUGR) is the term used to designate a fetus that has not reached its growth potential. However it is difficult to make a distinction between infants who are constitutionally small and growth restricted small. In the present study, we focused on the clinical characteristics and the hematologic value in small for gestational age (SGA) infants and discussed how to distinguish intrauterine growth restricted infants from constitutionally small infants. Methods: SGA infants that did not have any other risk factors for IUGR in the medical record except maternal hypertension (HTN) and diabetes mellitus (DM) and born at the Seoul St Mary's Hospital and Yeouido St Mary`s Hospital from January 2007 to July 2010 were included. The frequency of IUGR is higher in the pregnancy with medical problem, and in preterm infants. Therefore, the data was categorized by maternal disease and gestational age. We assessed the clinical data and the hematologic value. Results: The leukocyte count and the platelet count were lower in the SGA with maternal HTN group and the preterm SGA group. There was no difference in the clinical data and the prognosis resulted from maternal HTN and maternal DM. However, the hematologic difference was not found in the categorization of the preterm SGA group as maternal diasease. Conclusion: The results of this study showed that it is possible the low leukocyte count and the low platelet count are the characteristic hematologic features in growth restricted small for gestational age infants.

Background: Chronic obstructive pulmonary disease (COPD) is characterized by airflow limitation that is not fully reversible. COPD has systemic effects, such as skeletal muscle dysfunction and abnormal weight loss. It also has been suggested that COPD is related to other chronic disease, such as cardiovascular disease, osteoporosis, and anemia. The aim of this study was to evaluate a symptom questionnaire and laboratory findings in subjects with air flow limitation. Methods: We evaluated a symptom questionnaire and laboratory findings in subjects with airflow limitation detected by spirometry in conjunction with the Second Korean National Health and Nutrition Examination Survey. A total of 9,243 adults over the age of 18 were recruited. Among the adults, we finally analyzed 2,217 subjects who met the acceptability and repeatability criteria of spirometry, showed normal findings on chest radiography, and were older than 40 years of age. Results: There were 288 subjects with airflow limitation as determined by spirometry. The frequency of respiratory symptoms such as cough, sputum and wheezing were significantly higher in subjects with airflow limitation (p <0.01). Hemoglobin and hematocrit levels were higher in subjects with airflow limitation (hemoglobin level 13.98 mg/dL vs. 13.62 mg/dL, hematocrit 42.10% vs. 40.89%; p<0.01). The HDL cholesterol level was lower in subjects with airflow limitation (44.95 mg/dL vs. 45.60 mg/dL; p<0.01). There was no significant difference in the total cholesterol, triglyceride, blood urea nitrogen, creatinine, and fasting glucose levels. Conclusion: In subjects with airflow limitation, prevalence of respiratory symptoms was higher than in normal spirometry subjects and the levels of hemoglobin and the hematocrit were higher. The HDL cholesterol level was lower in subjects with airflow limitation.

Purpose : Kawasaki disease is notorious for coronary arterial complication which is usually developed as a febrile disease in early childhood. Increased polymorphonucleus(PMN) cell levels in acute phases may be associated with the pathophysiology of Kawasaki disease. We studied the relationship between coronary arterial dilatation and elastase activity which was excreted from PMN cell and roles as an important factor for vasculitis. Methods : Ten patients diagnosed with Kawasaki disease in Yonsei University Medical Center were examined between November, 2001 and January, 2002. In addition, 15 patients with other febrile diseases were also examined. Echocardiography was done in patients with Kawasaki disease on the first day of admission and four weeks after the onset of the disease. At each time, venous samples were drawn and separated into plasma and leukocytes. In patients with other febrile disease, samples were drawn on admission. Elastase activities in plasma and neutrophil extracts were measured. Results : The significant increased plasma elastase activity, $6.19{\pm}0.74U/mL$, found in Kawasaki disease patients compared with the other febrile disease patients, $4.86{\pm}1.17U/mL$(P<0.05). And there was no significance between the above two diseases in terms of the elastase activity in neutrophil extracts. The relationship between initial elastase activity and the coronary arterial complication which was shown in subacute phase wasn't significant. Conclusion : Plasma elastase activity was increased in Kawasaki disease significantly, but the initial plasma elastase activity in the acute phase could not reflect the range of coronary arterial complication.

Although water is an essential component of the human body and is involved in many physiological processes, the effect of a steady and sufficient water intake on blood components has not well elucidated. Therefore, we investigated the changes in hematological parameters, high-sensitivity C-reactive protein (hs-CRP), and immunoglobulin G (IgG) after water intake in 13 healthy adults. They were divided into two groups: The control group (N=4), which consumed water ad libitum, and the experimental group (N=9), which consumed 2 L of water per day. Two weeks later, blood cell counts, hematocrit, and hemoglobin content had increased in the experimental group, although not significantly (p>0.05); however, there was a significant increase in the mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) (p<0.05; and p<0.01, respectively), and a significant decrease in the mean platelet volume (MPV) (p<0.05). Of the immunologic parameters, a non-significant decrease in the concentration of hs-CRP, an indicator of cardiovascular disease risk, was observed (p>0.05). However, there was a dramatic and significant increase in the concentration of IgG (p<0.05). In conclusion, a steady and sufficient water intake may contribute to alleviate anemia by increasing hemoglobin. Additionally, it may decrease the risk of cardiovascular disease by decreasing platelet activation and concentration of hs-CRP. Furthermore, a steady intake of water may improve immune function by increasing the concentration of the components of humoral immunity.

Purpose : To evaluate late gadolinium enhancement (LGE) pattern of left ventricular (LV) myocardium and presence or absence of LGE in other regions of the heart on cardiac magnetic resonance (CMR) imaging in patients diagnosed with cardiac amyloidosis. Materials and Methods: From 2009 to 2011, 9 patients who were suspected cardiac amyloidosis underwent CMR. We retrospectively analyzed the presence or absence of LGE and enhancement pattern in LV myocardium, and the presence or absence of LGE in other chambers as well. Also we measured interatrial septal thickness (IST), relative signal intensities of atrial septum and epicardial fat over the left atrial (LA) cavity on delayed enhanced images. MRI parameters in these patients were compared to those of control group of patients with ischemic heart disease by Wilcoxon rank sum test. Results: Of nine patients, LGE were found in 8; subendocardial circumferential pattern in 4 and diffuse pattern in 4. LGE in right ventricle was observed in 7. IST was significantly increased in patients with cardiac amyloidosis (P = 0.02). Ratio of atrial septum to LA cavity and ratio of epicardial fat to LA cavity showed a significant difference (P = 0.0002 and P = 0.0006, respectively). Conclusion: In LGE CMR, subendocardial or diffuse enhancement pattern is a typical finding for patients with cardiac amyloidosis. Atrial septum and epicardial fat show relatively increased signal intensities over LA blood cavity.

This study investigated the effect of bamboo salt (BS) on body gain, feed intake, meat composition, and blood characteristics of broiler chicks. BS was processed by roasting salt at $1,200{\sim}1,300^{\circ}C$ in a bamboo container, with the open end plugged with red clay. In total, 120 broiler chicks were assigned to four treatments. Each treatment was triplicated, with 10 chicks in each treatment group. The supplementation levels of the three BS-treated feeds were 0.1, 0.2, and 0.3%. Body weight gain slightly increased in broiler chicks fed diets supplemented with BS compared to that of the control during the overall test period. However, no significant differences were observed among treatments. Feed intake was also not significantly different among treatments. Feed efficiency was significantly (p<0.05) improved in broiler chicks fed diets supplemented with BS compared to that of the control. Body weight gain was more positively affected by the dietary BS supplement at the beginning of the experimental period than toward the end. Water intake was positively correlated with the dietary 0.3% BS level (p<0.05). Breast meat composition and cholesterol levels were also not affected by BS supplementation. The total protein, albumin, glutamic oxaloacetic transaminase (GOT), glutamic-pyruvic transaminase (GPT), and total cholesterol levels in the blood were not significantly different among treatments.

The purpose of this study was to investigate the effect of three different mulberry cultivars extracts on inhibition of platelet aggregation and blood flow improvement. Four groups were surgically ovariectomized (OVX). The fifth group was sham operated. Sprague-Dawley strain female rats were randomly assigned to the following groups. sham-operated rats(Sham), ovariectomized control rats(OVX-Control), ovariectomized rats supplemented with 80% ethanol extracts from fruits of Tajikistan mulberry (OVX-TM), Korea mulberry (OVX-KM) and China mulbery (OVX-CM) at 200 mg/kg bw/d. The mulberry extracts were orally administrated at 1 ml per day. The body weights of OVX rats were significantly heavier than the sham-operated rats at all values (p<0.05). The serum triglyceride level was significantly decreased after supplemented with the CM and KM extracts. The serum HDL-cholesterol level in the OVX-KM group was significantly higher than that in the OVX-control group. The passage time of whole blood showed significant correlation with triglyceride but reverse correlation with HDL cholesterol. The ability of platelet aggregation of groups treated with mulberry extracts was less than OVX-control group. Taken these together, mulberry extracts may be used to possibly improve the quality of life in menopausal women.

This study aimed to compare the effects of microcurrent stimulation and rest on the fatigue index by applying both to subjects who had accumulated fatigue after performing short-duration physical activity. The experiment was performed at S University from December 2012 to February 2013, on 22 healthy men in their 20s, who were right-handed, and without peripheral or musculoskeletal diseases. All subjects lifted a 10-kg box lift and lower 100 times in 15 minutes. Immediately after that, muscle fatigue index (Median Frequency: MF) and blood fatigue index (Creatine Kinase Lactate: CK, Lactate Dehydrogenase: LDH) were measured by using surface electromyography. The subjects were divided into two groups, and microcurrent stimulation and rest were mediated to the experimental and control groups, respectively, for 20 minutes. After intervention, muscle fatigue index and blood fatigue index were measured and the changes in the accumulated fatigue index were compared. Both groups manifested significantly decreased cumulative fatigue after applying the mediation compared to the pre-intervention level (p < .05), the only exception being the fatigue index of the left erector spinae in the rest group. Compared to the rest group, the microcurrent stimulation group showed a significant decrease in muscle fatigue index (p < .05) but no significant differences were found in the blood fatigue index. Given the results of this study, microcurrent stimulation is considered to be helpful in muscle fatigue recovery for workers who have to perform repetitive movements lifting weights, and additional studies on the correlations of the fatigue recovery with respect to the long-term follow-up of fatigue index and mediation time are necessary.
