Calcium concentration in the bone resorption lacunae is high and is in the mM concentration range. Both osteoblast and osteoclast have calcium sensing receptor in the cell surface, suggesting the regulatory role of high extracellular calcium in bone merabolism. In vitro, high extracellular calcium stimulated osteoclastogenesis in coculture of mouse osteoblasts and bone marrow cells. Therefore we examined the genes that were commonly regulated by both high extracellular calcium and 1,25(OH)_(2)vitaminD_(3)(VD3) by using mouse oligo 11 K gene chip. In the presence of 10 mM[Ca^(2+)]e or 10 nM VD3, mouse calvarial osteoblasts and bone marrow cells were co-cultured for 4 days when tartrate resistant acid phosphatase-positive multinucleated cells start to appear. Of 11,000 genes examined, the genes commonly regulated both by high extracellular calcium and by VD3 were as follows; 1) the expressions of genes which were osteoclast differentiation markers or were associated with osteoclastogenesis were up-regulated both by high extracellular calcium and by VD3; trap, mmp9, car2, ctsk, ckb, atp6b2, tm7sf4, rab7, 2) several chemokine and chemokine receptor genes such as sdf1, scya2, scyb5, scya6, scya8, scya9, and ccr1 were up-regulated both by high ectracellular calcium and by VD3, 3) the genes such as mmp1b, mmp3 and c3 which possibly stimulate bone resorption by osteoclast, were commonly up-regulated, 4) the gene such as c1q and msr2 which were related with macrophage function, were commonly down-regulated, 5) the genes which possibly stimulate osteoblast differentiation and/or mineralization of extracellular matrix, were commonly down-regulated;slc8a1, admr, plod2, lox, fosb, 6) the genes which possibly suppress osteoblast differentiation and/or mineralization of extracellular matrix, were commonly up-regulated;s100a4, npr3, mme, 7) the genes such as calponin 1 and tgfbi which possibly suppress osteoblast differentiation and/or mineralization of extracellular matrix, were up-regulated by high extracelluar calcium but were down-regulated by VD3. These results suggest that in coculture condition, both high extracellular calcium and VD3 commonly induce osteoclastogenesis but suppress osteoblast differentiation/mineralization by regulating the expression of related genes.

Baseball is rapidly getting popularity in Korea as it has been in U.S.A and Japan. During the last decade, threre were several studies about baseball injuries which oriented mainly to the overuse injuries of growing baseball players. But there was no study the professional baseball players systematically. This study was surposed to see the general characteristics of baseball injuries and to provide the prevention and rehabilitation programs if recommended. The number of 83 injuries of 60 baseball players was analysed according to the position, injury site, diagnosis, injury mechanism and duration of injury. The mean age and height of 60 subjects were 24.6 years old and 180.65㎝, respectively. The baseball position of 82 injured cases were composed of 27 pitchers, 30 infielder, 19 outfielder and 6 catchers. The characteristics of injury were as follows: 1.The number of chronic injury was 56 cases(68.3%) and the percentage of chronic injury of pitchers was up to 81.5% compared 73.3% of infielder and 47.4% of outfielder. 2. The injury rate of both lower and upper extremitis were equal and the rate of lower back problems was the second, which should be concerned. 3. The number of cases injured by direct collison is as low as 15(18.3%). The most common secondary cause of injury was aggressive throwing itself and 26 out of 49 cases injured not by direct collision. 4. More concern should be payed about the low back problems and about the catcher and the field players as much as pitchers from now one.

Bacillus species related to food poisoning

Oh, Mi-Hwa,Kim, Gun-Hee 식물자원연구소 덕성여자대학교 2006 植物資源硏究誌 Vol.5 No.-

The major concern in the food industry is the outgrowth of pathogenic Bacillus species which have the potential to cause a food poisoning incident. Bacillus cereus is the most prevalent pathogenic Bacillus species found in food and other industrial processes. However, other species in the genus Bacillus, including B. subtilis, B. licheniformis, B. brevis, B. pumilus and B. thuringiensis have been implicated as potential agents of food poisoning.

목적 : 한강성심병원에서는 2000년 3월 반코마이신내성 장구균이 처음 분리되어, 원내전파를 막기 위한 노력을 하였으나, 분리가 지속되었다. 따라서 이에 대한 좀더 자세하고 객관적인 자료를 얻기 위해 본원에서 분리된 반코마이신내성 장구균에 대한 임상분자 역학적 연구를 시행하게 되었다. 방법 : 2000년 3월부터 2001년 2월까지 한림대학교 한강성심병원에서 분리된 장구균을 대상으로 디스크 확산법, 최소발육억제 농도등의 측정을 통해 반코마이신 내성여부를 확인하였으며, 반코마이신내성 장구균을 대상으로 PFGE를 시행하여 형별 분석을 하였다. 결과 : 분리된 균주는 총 32균주로 모두 E. faecium이었다. 항생제 내성 검사 결과 모두 Van A형이었다. PFGE 결과 1a형이 8검체, 1b형이 5검체, 2a형이 4검체, 2b형이 4검체, 3a형이 2검체, 3b형이 5검체였고, 그 외 4, 5, 6형이 각각 1검체씩이었다. 총 32균주 중 56%(18/32)의 균주가 같은 시기, 같은 병실에서 동일한 PFGE 형을 보이면서 분리되었다. 결론 : 반코마이신내성 장구균의 PFGE 분석 결과 여러 종류의 반코마이신내성 장구균이 유행하였음을 알 수 있다. 그러나 같은 기간, 같은 병실에서 분리된 균주의 PFGE 형이 같은 것이 상당수 있었다. 이는 반코마이신내성 장구균의 원내 전파가 있었음을 의미한다. 따라서 반코마이신내성 장구균의 전파의 발생 및 전파 방지를 위해서는 보다 효과적인 감염관리 활동이 필요할 것으로 생각된다. Background: Vancomycin-resistant enterococci(VRE) have been a rising problem worldwide. In March 2000, VRE was first isolated from a patient in Hangang Sacred Heart hospital. Although efforts to prevent transmission of VRE were performed, isolations continued. So molecular epidemiological study of VRE was done. Method : The minimal inhibitory concentration(MIC) to vancomycin and teicoplanin, and pulsed field gel electrophoresis(PFGE) pattern of VRE isolated from March 2000 to February 2001 were evaluated. Results : 32 VRE were isolated. All of the VRE were Enterococcus faecium and showed Van A resistance phenotype. We found out that a significant number of VRE isolated during same period and in same room, were same PFGE patterns. (18 cases/ 32 isolates= 56%) Conclusion: This study demonstrated the spread of VRE of same PFGE patterns. It suggests the nosocomial spreads of VRE.

Objectives: This clinical study reports the effects of Cheonggansoyo-san (CSS) on three patients with glossodynia. Methods: Three patients with glossodynia were treated with CSS (i.e., an herbal medicine) and acupuncture. Numeric rating scales (NRSs) for glossodynia and dry mouth and hwa-byung questionnaire scores were evaluated, and the results from heart rate variability (HRV) evaluations were analyzed. Results: After treatment with CSS, three patients' glossodynia symptoms, such as burning sensations, tingling, and numbness of the tongue, were improved. NRS ratings for glossodynia and dry mouth and the hwa-byung questionnaire scores also improved, and HRV parameters were closer to the normal range. Conclusion: Cheonggansoyo-san could be used to treat glossodynia.

혈액에서 분리된 Extended-Spectrum Cephalosporin 내성 Enterobacter cloacae에서 Plasmid-Mediated Quinolone Resistance 유전자의 분포 및 Fluoroquinolone 감수성 양상

김연재,서미란,김지은,최은화,이환종,배현주 대한감염학회 2009 감염과 화학요법 Vol.41 No.5

Background : Extended-spectrum cephalosporins (ESCs)-resistant Enterobacter cloacae is one of the pathogens of nosocomial infection the incidence of which is on the rise. Moreover, plasmid-mediated quinolone resistance genes (PMQR genes) that reduce quinolone sensitivity have been shown to be widely distributed among clinical isolates of Enterobacteriaceae. This study was carried out to observe the distribution of PMQR genes in clinical isolates of E. cloacae resistant to ESCs. Materials and Methods : Fourty-three ESCs-resistant E. cloacae strains from the blood collected during the span of 7 years, from 1994 to 2001, at Seoul National University Children’s Hospital (SNUCH) were included in this study. Isoelectric focusing and enzyme specific PCR were performed to characterize β-lactamase. The presence of qnrA, qnrB, qnrC, qnrS, qepA, and aac(6’)-Ib-cr was determined by PCR, restriction enzyme analyses of PCR products, and DNA sequencing. Minimal inhibitory concentration (MIC) of several quinolones was measured by agar dilution method. Results : The PMQR genes were detected in 9 (21%) of 43 ESCs-resistant E. cloacae isolates. Among them, five isolates were positive for qnrB2, and each two isolates harbored qnrB4 or qnrB5, respectively. qnrA, qnrC, qnrS or qepA was not identified. aac(6’)-Ib was detected in 27 isolates, but aac(6’)-Ib-cr was not found. Among the 9 qnrB-positive isolates, 5 produced SHV-12, 3 were derepressed mutants, and 1 produced pI 7.5 β-lactamase. MIC ranges and percent resistances of nalidixic acid, ofloxacin, levofloxacin, and moxifloxacin for the PMQR genes-positive isolates were higher than PMQR genes-negative isolates. Conclusions : In this study, ESCs-resistant E. cloacae showed a high prevalence of PMQR genes, and qnrB was the only PMQR gene identified.
