Background: Low cardiac output syndrome (LCOS) after cardiac surgery usually requires inotropes. In this setting, critical illness-related corticosteroid insufficiency (CIRCI) may develop. We aimed to investigate the clinical features of CIRCI in the presence of LCOS and to assess the efficacy of steroid treatment. Methods: We reviewed 28 patients who underwent a rapid adrenocorticotropic hormone (ACTH) test due to the suspicion of CIRCI between February 2010 and September 2014. CIRCI was diagnosed by a change in serum cortisol of <$9{\mu}g/dL$ after the ACTH test or a random cortisol level of <$10{\mu}g/dL$. Results: Twenty of the 28 patients met the diagnostic criteria. The patients with CIRCI showed higher Sequential Organ Failure Assessment (SOFA) scores than those without CIRCI ($16.1{\pm}2.3$ vs. $11.4{\pm}3.5$, p=0.001). Six of the patients with CIRCI (30%) received glucocorticoids. With an average elevation of the mean blood pressure by $22.2{\pm}8.7mm\;Hg$ after steroid therapy, the duration of inotropic support was shorter in the steroid group than in the non-steroid group ($14.1{\pm}2.3days$ versus $30{\pm}22.8days$, p=0.001). Three infections (15%) developed in the non-steroid group, but this was not a significant between-group difference. Conclusion: CIRCI should be suspected in patients with LCOS after cardiac surgery, especially in patients with a high SOFA score. Glucocorticoid replacement therapy may be considered to reduce the use of inotropes without posing an additional risk of infection.

본 연구는 스테로이드 성호르몬인 에스트로겐(estrogen), 테스토스테론(testosterone) 및 노르테스토스테론(19-nortestosterone)이 암, 수 돼지 지방전구세포의 증식과 분화에 미치는 영향을 구명하기 위해서 수행하였다. 지방전구세포는 암, 수 갓 난 돼지의 등지방 조직을 떼어 내어 collagenase를 처리한 후 분리해서 $CO_2$ 배양기에서 배양했다. 세포 배양 중에 $10^{-7}M$와 $10^{-6}M$의 스테로이드 성호르몬을 처리했다. 먼저 지방전구세포의 증식에 미치는 영향을 보면, 암퇘지에서 분리한 지방전구세포의 증식을 높은 농도의 스테로이드 성호르몬 모두가 촉진했다. 수퇘지에서 분리한 지방전구세포의 증식은 에스트로겐과 테스토스테론만이 촉진했다. 지방세포의 분화에 미치는 작용을 보면, 세 호르몬 모두, 농도에 관계없이 암수 성별에 관계없이 지방전구세포의 분화를 촉진했다. 촉진 정도는 증식보다 분화에 더 크게 나타났다.

Purpose: Steroid dependent nephrotic syndrome (SDNS) is a chronic illness in childhood hard to treat. Steroid sparing drugs are often used, because long-term steroid therapy can cause severe side effects. We studied to compare efficacy between MMF and other drugs including cyclosporine and levamisole. Methods: This study was performed retrospectively on patients with SDNS, who were treated at Pusan National University Children's hospital. MMF group included 11 patients who were treated with MMF for at least six months between June 2012 and July 2014. As control groups, cyclosporine group (n=15) and levamisole group (n=18) included patients treated between January 2008 and July 2014. Number of relapse was analyzed in patients treated more than six months, and relapse free for one year was analyzed in patients treated more than one year. Results: In MMF group, ten were boys and mean age at onset was 5.8 years. Mean age at starting of MMF was 8.6 years. Number of relapse in MMF group was reduced significantly after treatment from 3.4 /year to 0.2 /year (P=0.003). There was no significant difference in number of relapse among groups (MMF: 0.2 /year, cyclosporine: 0.5 /year, levamisole: 0.5 /year). Comparing the early relapse within six months after treatment levamisole group was significantly higher than the other two groups (P=0.04). Conclusions: MMF which is used in SDNS significantly reduced the relapse and side effects were rare. In addition, MMF did not show any significant difference in comparison with the other two groups in number of relapse and relapse free for one year.

경부 신경근병이 의심되는 31예의 환자에 경막외강 스테로이드 주입으로 치료하여 다음과 같은 결과를 얻었다. 1) 총 31예중 10예에서는 1회만을 주입하였다. 2) 최소한 1주일 간격으로 2회이상 주입한 21예중 15예에서 증상의 호전을 보였고 6예에서는 효과가 없었다. 3) 총 88회 주업중 2회의 지주막 천자외에는 합병증이 없었다. 이상의 결과로 보아 cervical radiculopathy가 의심되는 환자는 수술적 치료를 적용하기 전에 다른 종류의 대중적 치료와 더불어 경막외 스테로이드률 주입하는 것이 안전하고 효과적인 것으로 사료된다.

CGD 환자에서는 면역 체계의 결함으로 인한 반복적인 감염과 육아종 형성이 특징적이다. CGD 환자에서 육아종의 형성에 의한 식도 폐쇄는 매우 드문 합병증 중 하나로 CGD 환자의 육아종 형성에 의한 식도 폐쇄의 치료에 대해서는 불현성 감염이 동반될 가능성이 있어 스테로이드 치료와 항생제 치료에 대한 논란이 있어왔다. 저자들은 항생제 치료에 반응하지 않는 육아종 형성에 의한 식도 폐쇄 증상을 보인 8세 만성육아종질환 환자를 보고하는 바이다. 환자는 스테로이드 치료 이후에 임상적 증상과 영상 검사 상의 급격한 호전을 보였으나 스테로이드 치료를 중단한 지 한 달 뒤 환자의 식도 폐쇄 증상은 재발하였고, 이는 스테로이드를 재 투약 후 호전되었다. 스테로이드 중단 이후 한 차례 다시 재발하였으나, 항생제 치료 후 호전되었고 이후 추가적 재발 없이 경과 관찰 중이다.

Background: Epidural steroid injection (ESI) is one of the most common procedures for patients presenting low back pain and radiculopathy. However, there is no clear consensus on what constitutes appropriate steroid use for ESIs. To investigate optimal steroid injection methods for ESIs, surveys were sent to all academic pain centers and selected private practices in Korea via e-mail. Methods: Among 173 pain centers which requested the public health insurance reimbursements for their ESIs and were enrolled in the Korean Pain Society, 122 completed questionnaires were returned, for a rate of 70.5%; also returned were surveys from 39 academic programs and 85 private practices with response rates of 83.0% and 65.9%, respectively. Results: More than half (55%) of Korean pain physicians used dexamethasone for ESIs. The minimum interval of subsequent ESIs at the academic institutions (3.1 weeks) and the private practices (2.1 weeks) were statistically different (P = 0.01). Conclusions: Although there was a wide range of variation, there were no significant differences between the academic institutions and the private practices in terms of the types and single doses of steroids for ESIs, the annual dose of steroids, or the limitations of doses in the event of diabetes, with the exception of the minimum interval before the subsequent ESI.

Manchurian trout (Brachymystax lenok) is an endangered fish species in East Asia including the Korean peninsula. To establish a method for artificial propagation and to improve our understanding of the reproduction in the species, we have produced recombinant gonadotropins, follicle-stimulating hormone (r-mtFSH) and luteinizing hormone (r-mtLH), which may play central roles in reproductive activities. In the present study, the biological activities of the recombinant hormones were analyzed by gonadosomatic index (GSI), ovarian follicle diameter, and sex steroid levels in mature rainbow trout (Oncorhynchus mykiss). In the 6th day post-injection, FSH-injected fish were slightly decreased in the GSI value, although there were no significant differences among those of control, r-mtFSH, and r-mtLH treatments. Injection of the r-mtFSH increased follicle diameters significantly as compared with those of control- and r-mtLH-injected fish. The plasma steroid levels showed wide differences in the groups at 1, 3, or 6th day post-injection. Despite the variable steroid levels, three individuals receiving either r-mtFSH or r-mtLH showed a great increase in a maturation-inducing steroid, $17{\alpha},20{beta}$-dihydroxy-4-pregnen-3-one, at 3 and 6 days. Taken together, these results suggest that biological efficacies of the recombinant FSH and LH should be further studied in the Manchurian trout.

Myogenic satellite cells (MSCs) are adult stem cells that activate and differentiate into myotubes. These stem cells are multipotent as they transdifferentiate into adipocyte-like cells, nerve cells and osteocytes. The effects of steroid hormones ($E_2$ and testosterone) were studied as a further step toward understanding the mechanism of MSCs proliferation and differentiation. In this study, MSCs were grown continuously for 87 days, implying that there may be a group of MSCs that continue to proliferate rather than undergoing differentiation. Isolated MSCs were cultured in Dulbecco's Modified Eagle's Medium supplemented with adult male, female or castrated bovine serum to observe the effect of steroid hormones on MSC proliferation. Cell proliferation was the highest in cultures supplemented with male serum followed by female and castrated serum. The positive effect of male hormone on MSC proliferation was confirmed by the observation of testosterone-mediated increased proliferation of cells cultured in medium supplemented with castrated serum. Furthermore, steroid hormone treatment of MSCs increased lipid accumulation in myotubes. Oil-Red-O staining showed that 17${\beta}$-estradiol ($E_2$) treatment avidly increased lipid accumulation, followed by $E_2$+testosterone and testosterone alone. To our knowledge, this is the first report of lipid accumulation in myotubes due to steroids in the absence of an adipogenic environment, and the effect of steroid hormones on cell proliferation using different types of adult bovine serum, a natural hormonal system. In conclusion, we found that sex steroids affect MSCs proliferation and differentiation, and lipid accumulation in myotubes.
