Objectives : The authors recently found a suggestive evidence of linkage of chromosome 8p21-12 to schizophrenia in Korean multiplex families. Neuregutin 1 (NRGI) was identified in this locus as a positional and functional candidate gene for Schizo-phrenia, through several independent studies with European and Chinese populations. The purpose of this study is to determine whether NRGl is associated with schizophrenia in Korean population. Methods : Three SNPs (SNP8NRG221533, SNP8NRG241930, SNP8NRG243177) and two microsatellites markers (478B14-848,420M9-1395) located at the 5' end of NRGI were genotyped for 242 unrelated schizophrenia patients and the same num-ber of normal controls. Genetic association was tested by χ²-test (df=1). Not only for the whole patients group but also for asubgroup of patients with auditory hallucination. This subtype showed stronger linkage with chromosome 8p12 in the prior study of the authors with multiplex families. Results : G allele of SNP8NRG241930 was significantly in excess in the subgroup of patients with auditory hallucination compared to the control group (p=0.03, 0R=1.76). We also found that 3 SNPs haplotype TTC (p=0.04, 0R=0.58) and five markers haplotype TTC53 (p=0.01,0R=0.49) were associated with schziophrenia with a protective effect. Three SNPs haplotype CGT which is a part of the at-risk haplotype of the Icelandic schizophrenia families was found in excess in the patients group but no significant association was observed. Conclusion : NRGI might either play a mle in the predisposition to schizophrenia or be in linkage disequilibrium with a causal locus of this illness.

Background : Enterococci are important cause of nosocomial infections. Recently, vancomycin-resistant enterococci (VRE) has been increasingly reported as significant nosocomial pathogens. Therefore, accurate identification of enterococcal species is a prerequisite step for the appropriate antibiotic treatment and epidemiologic surveillance. We wanted to know the usefulness of PCR method compared with Vitek automatic identification system. Methods : Totally 105 isolates were identified on the species level by Vitek (GPI card and software version R06.1), methyl-α -D-glucopyranoside test, and PCR methods. Results : Among 105 enterococcal isolates, 59 were identified as E. faecium, 11 E. faecalis, 6 E. gallinarum by Vitek. But 29 isolates (28%) were unidentified. Subsequently all of these isolates were analyzed by PCR, the results of which were as follows : 17 E. faecium, 5 E. casseliflavus, 7 E. gallinarum. Two isolates identified as E. gallinarum by Vitek were reidentified as E. casseliflavus by PCR and other methods far phenotypic characterization. Conclusoin : PCR method was more accurate and sensitive than Vitek for the identification of enterococci species. (Korean J Infect Dis 33:123∼127, 2001)

저자들은 국내에서 처음으로 중합효소연쇄반응 검사를 통하여 B. microti에 의한 인체 바베시오시를 진단하였으며, atovaquone과 azithromycin 병합요법을 사용하여 치유한 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Human babesiosis is a tick-borne infectious disease caused by Babesia species. The clinical diagnosis is difficult because of nonspecific symptoms like flu. Rapid diagnosis of human babesiosis is microscopic examination in peripheral blood smear (Giemsa-stain) which reveals characteristic forms of an intracellular quadruplet parasite. But differentiation between Babesia microti and Plasmodium species can be quite difficult because of the morphologic similarity. We experienced a case of human babesiosis. The patient was a 62-year old Korean male who had been in New Jersey, U.S.A for 2 months. We initially diagnosed as malaria infection because the peripheral blood smear revealed intracellular single ring form organism. But the patient was not improved significantly by the treatment with chloroquine regimen. Finally we confirmed human babesiosis by polymerase chain reaction for Babesia microti. We treated the patient successfully with a regimen of atovaquone and azithromycin which has fewer adverse reactions than a regimen of clindamycin and quinine.

Amyloidosis is a disease resulting in deposition of amyloid in the body. The disease can be either primary or secondary. The amyloidosis of urinary bladder is more usually affected by primary amyloidosis and also very rare. The patient with primary amyloidosis of the bladder usually presents with gross hematuria. The amyloidosis resembles bladder cancer in cystoscopy. It can be confirmed by biopsy. The treatment consists of medication (e.g., steroid, antitumor agent, cholchicine, DMSO) and/or transurethral resection. The standard treatment is mephalan and prednisolone. A 49-year-old man complained of recently developed gross hematuria without abdominal pain. We examined urinary bladder cystoscope for gross hematuria. It revealed small bulging mass on trigone are a of bladder. Therefore we did bladder biopsy. Finally, it revealed bladder amyloidosis. The patient was improved by medication (mephalan 2mg and prednisolone 1 mg/kg po daily). We report an unusual case of amyloidosis involving bladder.

This study was designed to exam the aged's needs for spiritual nursing care. The purpose was to serve as a basis for the development of spiritual nursing practice. The major findings are as follows : 1. The degree of needs for spiritual nursing care as area was that needs of love and relationship mean 22.0, needs of meaning and object mean 28.2, needs of forgiving mean 13.5. Total needs for spiritual nursing care mean 63.7, which was on the upper middle level. The needs of meaning and object was rated highest. 2. Among the general characteristics of the subjects, needs of love and relatiohship wasn't significanlty different. 3. Among the general characteristics of the subjects, needs of meaning and object was significantly different according to two factors : age(F=7.260, p=0.001), religion(F=5.275, p=0.001). Higher needs of meaning and object was possessed by the older than the younger, by the one who have religion than the other. 4. Among the general characteristics of the subjects, four factors made a significantly difference to needs of forgiving : sex(t=-2.851, p=0.006), age(F=8.201, p=0.001), religion(F=6.928, p=0.000), disease(t=2.327, p=0.024). Higher needs of forgiving was possessed by man than woman, by the older than the younger, by the one who have religion than the other, by the one who have disease than the other.

Objective: The main purpose of this study is to analyze the risk factors for high neonatal serum magnesium concentrations in prenatal maternal magnesium therapy. Methods: This was a retrospective study that employed the electronic medical record systems of seven tertiary care centers under the College of Medicine, the Catholic University of Korea, from January 2009 to March 2021. This study was approved to use registry data and documentation of informed consent was waived by our Institutional Review Board (XC20WIDI0103/2020-2158-0020). Mothers who received antenatal magnesium sulfate for neuro-protection or eclampsia prophylaxis were included. This study evaluated mother-neonate pairs with each having one documented magnesium concentration measured from the blood. Results: A total of 877 mother -neonate pairs of magnesium concentration were obtained. Mothers of neonates with high neonatal magnesium concentrations (>4.5mg/dL) had high maternal magnesium concentrations, lower GFR, lower gestational age at delivery, and were more like to have preeclampsia. Conclusion: We have identified several predictors of neonatal serum magnesium concentrations that can guide maternal magnesium dose.

Measurement of Interleukin-33 (IL-33) and IL-33 Receptors (sST2 and ST2L) in Patients with Rheumatoid Arthritis

Hong, Yeon-Sik,Moon, Su-Jin,Joo, Young-Bin,Jeon, Chan-Hong,Cho, Mi-La,Ju, Ji Hyeon,Oh, Hye-Jwa,Heo, Yu-Jung,Park, Sung-Hwan,Kim, Ho-Youn,Min, Jun-Ki The Korean Academy of Medical Sciences 2011 JOURNAL OF KOREAN MEDICAL SCIENCE Vol.26 No.9

<P>The interleukin-33 (IL-33)/ST2 pathway has emerged as an intercellular signaling system that participates in antigen-allergen response, autoimmunity and fibrosis. It has been suggested that IL-33/ST2 signaling has been involved in the pathogenesis of rheumatoid arthritis (RA), because IL-33 and its receptor have been specifically mapped to RA synovium. The aim of this study was to determine the levels of IL-33 and sST2 in sera and synovial fluids in patients with RA. The serum level of IL-33 was significantly higher in patients with RA (294.9 ± 464.0 pg/mL) than in healthy controls (96.0 ± 236.9 pg/mL, <I>P</I> = 0.002). The synovial fluid level of IL-33 was significantly higher in RA patients than in osteoarthritis patients. The level of serum sST2 was higher in RA patients than in healthy controls (<I>P</I> = 0.042). A significant relationship was found between the levels of IL-33 and IL-1β (<I>r</I> = 0.311, <I>P</I> = 0.005), and IL-33 and IL-6 (<I>r</I> = 0.264, <I>P</I> = 0.017) in 81 RA patients. The levels of IL-33, sST2 and C-reactive protein decreased after conventional disease-modifying antirheumatic drugs treatment in 10 patients with treatment-naïve RA. Conclusively, IL-33 is involved in the pathogenesis of RA and may reflect the degree of inflammation in patients with RA.</P>

Biotransformation of (?)-α-Pinene by Whole Cells of White Rot Fungi, Ceriporia sp. ZLY-2010 and Stereum hirsutum

( Su Yeon Lee ),( Seon Hong Kim ),( Chang Young Hong ),( Ho Young Kim ),( Sun Hwa Ryu ),( In Gyu Choi ) 한국균학회 2015 Mycobiology Vol.43 No.3

Two white rot fungi, Ceriporia sp. ZLY-2010 (CER) and Stereum hirsutum (STH) were used as biocatalysts for the biotransformation of (-)-α-pinene. After 96 hr, CER converted the bicyclic monoterpene hydrocarbon (-)-α-pinene into α- terpineol (yield, 0.05 g/L), a monocyclic monoterpene alcohol, in addition to, other minor products. Using STH, verbenone was identified as the major biotransformed product, and minor products were myrtenol, camphor, and isopinocarveol. We did not observe any inhibitory effects of substrate or transformed products on mycelial growth of the fungi. The activities of fungal manganese-dependent peroxidase and laccase were monitored for 15 days to determine the enzymatic pathways related to the biotransformation of (-)-α-pinene. We concluded that a complex of enzymes, including intra- and extracellular enzymes, were involved in terpenoid biotransformation by white rot fungi.
