        Conditions for processing dried condiments with bloody clam were investigated. The enzymatic hydrolysis for 1 hour was more profitable than hydrothermal extraction to develop flavoring matters from bloody clam. As a result of omission tests, nucleotides were predominated in the taste compounds of bloody clam hydrolysates rather than free amino acids, and the contribution of nucleotides and free amino acids to the taste of bloody clam hydrolysates was remarkable. The major flavoring components of bloody clam hydrolysates were free amino acids and oligopeptides below 500 dalton. When bloody clam hydrolysates were separated with membrane(molecular weight cutoff 500 dalton) for recovering flavor, recovering yields of amino type nitrogen were 92.4%. Proximate compositions of dried condiments prepared with protease hydrolyzed bloody clam were moisture content 3.6%, total nitrogen were 71.2% amino nitrogen were 47.8%. And drying yield, solubility and absorption rates at Aw 0.88 were 21.4%. 86.3% and 6.6%, respectively.

        김은희,김철규,이순교,김순덕,이혜옥,권정순,이경미,이민미,심순미,유용만,신종식,강은희,이상일,김병식,오성태,육정환,박수길 한국의료QA학회 2003 한국의료질향상학회지 Vol.10 No.2

        Background : Gastric cancer is the most common malignant tumor in Korea. surgical operation is one of the major treatment modalities for gastric cancer patients. Therefore, gastrectomy is one of the most common procedures in General Surgery. There were variation in length of hospital stay and medical treatment for gastrectomy between three surgeons at Asan Medical Center. Clinical pathways have received considerable attention as a tool for recucing the medical practice variation, increasing the efficiency of care process, and improving the quality of care. The aim of this study was to evaluate the effect of a clinical pathway for gastrectomy in gastric cancer patients. Methods : The clinical pathway for gastrectomy was developed and implemented by a multidisciplinary group in Asan Medical Center. A computerized clinical pathway program was developed and revised after a pilot test. A total of 145 patients underwent gastrectomy by three surgeons at Asan Medical Center. We compared the length of hospital stay, patient satisfaction, and unplanned readmission rate between the pre-pathway group(n=67) and the post-pathway group(n=78). We also investigated the degree of satisfaction among the physicians and nurses who were main end-users of the clinical pathway. Results : The clinical pathway was applied to all target patients. The average length of hospital stay was shortened from 12.7days to 10.6days(p<0.01). The degree of patient satisfaction with the care process changed from 90.3% to 89.2% after the implementation of the clinical pathway, but the difference was of satistically significant(p=0.761). Unplanned readmission rate was 2.9% in the pre-pathway group. More than 90% of physicians and nurses answered that the clinical pathway had been a useful tool in their medical practice. Conclusions : The findings of the study demonstrated that implementation of the clinical pathway for gastrectomy produced substantial reduction in the length of hospital stay while improving the quality of patient outcomes. The computerized clinical pathway program can be used as one of the powerful patient management tools for reducing the practice variations and increasing the efficiency of care process in Korea hospital settings.

        Spectroscopic ellipsometry 은 다양한 물질의 광학적 특징을 연구할 수 있는 강력한 기술이다. 현재 실리콘 웨이퍼 위의 박막 분석에는 그 효율성이 확실히 입증되어 있다. 그러나 현재 산업은 유리 기판위의 박막을 분석하기를 원하고 있다. Ellipsometry로 투명기판을 분석하기 위해서는 후면 반사에의한 비간섭성 효과를 고려해야 한다. 기존의 반사공식을 투명기판의 비간섭성을 고려하여 수정하였다. 투명기판 위의 샘플과 scratch를 낸 같은 샘플을 측정 분석하여 정확성을 확인하였다. 수정된 반사공식을 이용하면 디스플레이와 같은 투명재료를 이용하는 곳에 유용하게 사용될 것으로 기대되고 있다. A Spectroscpic ellipsometry is very strong technology to study optical properties of many materials. It has already substantiated a analytic efficiency about thin films above wafers to be made of silicon. However, the current industry needs thin films analyzed on a glass. When we analyze a glass using a ellipsometry, we have to consider a efficiency of incoherence due to reflect at the back side. So then, we slightly altered the original formula. We compared a scratched sample with a sample on the glass, because off getting a exactitude. Our technical development, using the changed formula, is expected the useful utilization in a part of using gIasses such as display.

        석청에 포함된 grayanotoxin에 의해 독성 작용이 나올 수 있으며, 이러한 독성 작용은 일반적으로 24시간 이내 저절로 회복된다. 최근에 본 저자들은 석청 복용 후 발생한 심실빈맥을 경험하였기에 보고하는 바이다. 49세 남자가 호흡곤란으로 내원하였으며, 내원당시 분당 40회 정도의 동성 서맥이 관찰되었고, 수액을 투여하던 중 심실 빈맥이 발생하였다. 항부정맥제를 투여 후 정상 동율동으로 전환되었으며, 특별한 이상 없이 4일 후 퇴원하였다. Mad-honey intoxication caused by the consumption of honey producted from the nectar of rhododendrons. The grayanotoxins cause the intoxication. The toxic effects of mad-honey poisoning are rarely fatal and generally last for no more than 24 hours. We experienced one case, a 49 years-old man who presented with dyspnea after ingestion of mad-honey. He showed marked sinus bradycardia with < 40 beats per minute on admission. The cardiac rhythm was changed to ventricular tachycardia immediately. These features resolved completely in 24 hours with continuous infusion of amiodarone(600 mg per day) and fluids. We report the case of intoxication of mad-honey as a presentation of fatal cardiac arrhythmia.

        Brain magnetic resonance imaging (MRI) findings in central precocious puberty patients: is routine MRI necessary for newly diagnosed patients?

        Oh Ye Rim,Kim Yu Jin,Oh Kyeong Eun,Park Gyu Hyun,Kang Eungu,Nam Hyo-Kyoung,Rhie Young-Jun,Oh Saelin,Lee Kee-Hyoung 대한소아내분비학회 2023 Annals of Pediatirc Endocrinology & Metabolism Vol.28 No.3

        Purpose: The overall incidence of central precocious puberty (CPP) has increased in recent decades, and brain magnetic resonance imaging (MRI) evaluations are recommended in cases of suspected brain lesions. This study aimed to investigate the prevalence of MRI abnormalities and to evaluate the need for routine brain MRI in patients with newly diagnosed CPP. Methods: This retrospective study reviewed the data of patients newly diagnosed with CPP who underwent routine pituitary MRI at Korea University Anam Hospital from March 2020 to September 2021. A total of 199 girls and 24 boys was enrolled in this study. Positive MRI findings were categorized as abnormal pituitary, nonpituitary incidental, and pathological. In addition, we investigated the incidence of MRI abnormalities and evaluated their associations with clinical and biochemical factors. Results: Positive brain MRI findings were observed in 84 patients (37.7%). Pituitary abnormalities were found in 54 patients (24.2%), with Rathke cleft cysts being the most common (16.1%). Incidental nonpituitary findings were observed in 29 patients (13.0%), while a pathological brain lesion (diagnosed as hypothalamic hamartoma) was observed in only 1 female patient (0.4%). No significant differences in sex or age were found in incidence of pituitary abnormalities or nonpituitary incidental findings. Compared with headache controls, significant associations were observed between abnormal pituitary findings on MRI and CPP (unadjusted odds ratio, 3.979; 95% confidence interval, 1.726–9.173). Conclusion: True pathological findings were rare, even though the prevalence of abnormalities on pituitary MRI in patients with CPP was relatively high. Considering its cost-effectiveness, MRI screenings should be carefully considered in patients with CPP.

        Vesicoureteral Reflux and Renal Scarring in Children with Acute Pyelonephritis: the Role of Late 6-month Dimercaptosuccinic Acid Renal Scan

        Kyeong Eun Oh,임형은,Kee Hwan Yoo 대한소아신장학회 2020 Childhood kidney diseases Vol.24 No.2

        Purpose: The aim of this study is to evaluate the clinical utility of late 6-month dimercapto-succinic acid (DMSA) renal scan in predicting vesicoureteral reflux (VUR) and long-lasting renal scars in children with first acute pyelonephritis (APN). Methods: A retrospective case study of children admitted with APN from January 2010 to July 2017 was performed. The study included patients with voiding cystourethrography (VCUG) and acute and late 6-month DMSA scan. We analyzed the clinical, laboratory and imaging findings of patients with and without late cortical defects at 6 months and those with or without VUR. Results: Among 145 children with APN, 50 (34.5%) had cortical defects on the late DMSA renal scan and 60 (41.4%) showed VUR. Thirteen of 38 (34.2%) children undergoing 18-month DMSA renal scan showed a long-lasting renal scars. Compared with children without late cortical defects, patients with late 6-month cortical defects had a higher incidence of VUR and long-lasting renal scars, and relapse of UTI (all P <0.05). In a multivariable analysis, both high-grade VUR and relapse of UTI were independently correlated with the presence of late 6-month cortical defects (P <0.05). Late cortical defects and relapse of UTI were also associated with the presence of VUR (P<0.05). Only the late 6-mo cortical defects was an independent predictor of long-lasting renal scars in children with APN (P <0.05). Conclusion: An abnormal late 6-month DMSA renal scan may be useful in identifying VUR and long-lasting renal scars in children diagnosed with APN.

      • Differential DNA copy number aberrations in the progression of cervical lesions to invasive cervical carcinoma

        OH, EUN KYEONG,KIM, YONG-WAN,KIM, IN-WOOK,LIU, HAI-BO,LEE, KEUN-HO,CHUN, HEUNG JAE,PARK, DONG CHOON,OH, EUN-JEE,LEE, AH WON,BAE, SU MI,AHN, WOONG SHICK Spandidos Publications 2012 International journal of oncology Vol.41 No.6

        <P>Host genomic alterations in addition to human papillomavirus (HPV) are needed for cervical precursor lesions to progress to invasive cancer because only a small percentage of women infected by the virus develop disease. However, the genomic alterations during the progression of cervical lesions have not been systematically examined. The aim of this study was to identify differential genomic alterations among cervical intraepithelial neoplasia CIN1, CIN2, CIN3 and cervical squamous cell carcinoma (SCC). Genomic alterations were examined for 15 cases each of CIN1, CIN2, CIN3 and SCC by array-based comparative genomic hybridization (array CGH). The chromosomal regions showing significant differential in DNA copy number aberrations (DCNAs) among CIN1, CIN2, CIN3 and SCC were successfully identified by resampling-based t-test. The chromosomal regions of 5q35.3 and 2q14.3 showed significant DCNAs between CIN1 and CIN2, and between CIN2 and CIN3, respectively, while a significant difference in DCNAs between CIN3 and SCC was observed at 1q24.3, 3p14.1, 3p14.2, 5q13.2, 7p15.3, 7q22.1 and 13q32.3. In addition, the status of DCNAs in 1q43, 2p11.2, 6p11.2, 7p21.1, 7p14.3, 10q24.1, 13q22.3, 13q34 and 16p13.3 was conserved throughout the progression of CIN to SCC. The presence of differential and common DCNAs among CIN1, CIN2, CIN3 and SCC supports that the CIN progression may include continual clonal selection and evolution. This approach also identified 34 probe sets consistently overexpressed when amplified, suggesting an unbiased identification of candidate genes in SCC during cervical cancer progression.</P>

        Group B Streptococcal Renal Abscess in a 17-Year-Old Girl with Type 1 Diabetes Mellitus

        Kyeong Eun Oh,임형은,유기환 대한소아신장학회 2020 Childhood kidney diseases Vol.24 No.1

        Streptococcus agalactiae or group B streptococcus (GBS) is associated with infections in neonates and pregnant women. Herein, we describe a rare case of GBS renal abscess with peritonitis and pleural effusion in a 17-year-old girl with type 1 diabetes mellitus. The girl was admitted due to fever and right flank pain. Laboratory findings included leukocytosis and increased C-reactive protein level and erythrocyte sedimentation rate. Her serum glucose level was 484 mg/dL. Urinalysis showed no pyuria. Renal sonography revealed parenchymal swelling in the right kidney. The patient was administered intravenous cefotaxime. Urine and blood cultures were negative. Fever seemed to improve, but the following day, she complained of abdominal pain and fever. Antibiotic was switched to imipenem, and abdominal and pelvic CT revealed a ruptured right renal abscess, peritonitis, and bilateral pleural effusion with atelectasis. Pigtail catheter drainage of the abscess was performed. Culture from the abscess was positive for GBS, and fever subsided 2 days after the drainage. She was discharged with oral cefixime. The clinical course of urinary tract infections (UTIs) can be atypical in patients with diabetes, and GBS can be a cause of UTIs. Prompt diagnosis and management are necessary to prevent complications in patients showing atypical courses.
