몇 가지 종류의 corticosteroid에 대하여 액체 크로마토그래피-질량분석법으로 양이온 질량 스펙트럼을 얻었다. 화학구조에 따라 수소 첨가된 분자이온 [$MH^+$], 암모늄 첨가이온 [${MNH_4}^+$], 또는 ($MH^+-60$) 이온이 base peak였고 [$MH^+-18$] 또는 [${MNH_4}^+-18$] 이온 등이 특성적으로 나타났다. Methylprednisolone acetate를 male Sprague-Dawley rat에 경구투여한 다음 24시간 동안 배설된 뇨로부터 유리상태 또는 접합상태의 대사물질들을 가수분해, 추출 및 농축하고, thermospray LC/MS를 사용하여 양이온과 음이온 질량토막이온을 분석하였다. Methylprednisolone acetate의 C-21 위치에서의 탈아세틸화(deacetylation), C-20 위치에서 C=0의 -CHOH로의 환원, C-11 위치에서 CHOH의 C=0로의 산화 또는 C-17과 C-20 사이의 bond cleavage등에 의해 생성되는 것으로 추정되는 10여종의 대사물질을 검출하였다. 그 중에 20-hydroxymethylprednisolone(20-HMP), methylprednisolone(MP), methylprednisone(11-KMP)등은 표준물질과 비교 확인하였다.

We treated 19 cases of unicameral bone cysts with methylprednisolone acetate (MPA) from January 1988 to December 1995. We evaluated the effect of MPA injections through simple follow-up radiographs according to Oppenheim's, classification and retrospectively reviewed the sites of cyst, age of the patients at diagnosis, the incidence of pathologic fracture, cystic nature, and cystic proximiy to the growth plate, We then analyzed the relationship between these variables with the results of MPA injections. According to Oppenheim's classification, the results with the use of MPA injections were as follows: healed in six cases, improved in seven cases, incomplete obliteration in five cases and recurred in one case, If healed and improved were considered satisfactory results, then 13 cases(68.4%) were satisfactory at the last follow-up. Sites of cyst, age of the patients at diagnosis, incidence of pathologic fracture, cystic nature and cystic proximiy to the growth plate appeared not to influence the results of MPA injections statistically. On these data, we thought that the treatment of unicameral bone cysts with MPA injection was the most effective first choice of treatment before operative options such as curettage and bone graft.

목적: 성인의 단순성 골 낭종에서 스테로이드 주입법의 치료 효과를 알아보고자 한다. 대상 및 방법: 1998년 2월부터 2003년 2월까지 추시 가능한 11예를 대상으로 Needle aspiration 또는 천공술로 병변에 도달하여 낭종액을 배액후 Depo-medrol (methylprednisolone acetate, 신풍제약, Korea)을 1회 최소 80 mg에서 최대 200 mg까지 주입하였고, 추시 방사선 촬영은 투여 후 2주 간격으로 시행하였으며 약물 투여 후 6주에 시행한 단순 방사선 촬영에서 치유의 증거가 보이지 않을 경우, 8주에 추가적으로 스테로이드를 재 투여하였다. 최대 5회까지 시행하였고, 변형된 Neer의 분류법, Pentimalli 분류법, Scaglietti와 Sandra 분류법에 따라 결과를 판정하였다. 결과: 스테로이드의 한번 주입으로 치유된 예는 없었으며, 2회 주입 후 3예, 3회 주입 후 3예, 5회 주입 후 2예에서 치유되었고, 2예에서는 5회 주입 후에도 호전되지 않았으나, 증상의 변화가 없어 현재 관찰중이다. 1예에서는 2회의 스테로이드 주입 후에도 골 낭종의 크기가 증가되어 병적골절의 위험이 있어 수술적 치료를 시행하였다. Pentimalli 등의 단순 방사선 사진의 방사선학적 판정기준에 의해 결과를 평가하면, 1예에서 우수, 7예에서 보통이었고 3예에서 불량이었다. 결론: 스테로이드의 국소적 주입 요법은 성인에서도 효과적이며 일차적 치료법으로 고려할 수 있다.

The activity of taurine transporter is affected by various extracellular stimuli such as ion, hormone and stress. To assess effects of steroid hormones antral cyclosporin A (CsA) on the taurine transporter activity, murine monocytic RAW264.7 cell line was stimulated with dexamethasone (DM), triamcinolone (TA), cortisone (CS), hydrocortisone (HCS), prednisone (PSN), prednisolone (PSL) and methylprednisolone (MPSL) in the presence of 12-0-tetradecanoylphorbol-13-acetate(TPA). Treatment of TPA on the cell line led to significant reduction of taurine transporter activity. However, in case of stimulation of the cells with steroid hormones in the presence of TPA, all of them recovered TPA-induced reduction of the taurine transporter activity. Treatment of the cells with CsA led to significant reduction of the taurine transporter activity. Ionomycin (IM) recovered the reduced taurine transporter activity by CsA, but failed in the presence of EDTA, a calcium chelating agent. These results showed that glucocorticoid hormone recovered TPA-induced reduction of taurine transporter activity and that IM recovered CsA-induced reduction of the transporter activity by increasing intracellular free $Ca^{++}$ concentration.n.

경막외강으로 steroid 및 국소마취제투여는 요통치료에 유일한 방법만은 아니나 여러 대증요법중 가장 관심있는 방법중의 하나이다. 비록 요통이나 혹은 방사통이 동반된 경우에서 경막외강으로 steroid를 투여하여 매우 좋은 결과를 얻었다는 보고도 많다. 더우기 급성이며 짧은 병력올 가지고 수술을 받지 않을 경우에는 더욱 극적인 효과를 볼 수 있다. 경막외강으로는 steroid 단독 혹은 생리식염수나 국소마취제를 steroid의 희석제로 동시 사용하는 경우도 있다. 그러므로 steroid때문에 병세가 호전되었는지 혹은 희석제 때문에 호전 되였는지 분간하기 힘든 경우도 있었다. 그러나 투여후 즉각적인 성공적인 결과라 할지라도 지속성(longevity), 실현성(reality) 및 적응(indication)등에 문제가 있는 것은 사실이다.

This study investigated whether elevated host immune capacity can inhibit T. gondii infection. For this purpose, we used silk protein extracted from Bombyx mori cocoons as a natural supplement to augment immune capacity. After silk protein administration to BALB/c mice for 6 weeks, ratios of T lymphocytes ($CD4^+$ and $CD8^+$ T-cells) and splenocyte proliferative capacities in response to Con A or T. gondii lysate antigen (TLA) were increased. Of various cytokines, which regulate immune systems, Th1 cytokines, such as IFN-${\gamma}$, IL-2, and IL-12, were obviously increased in splenocyte primary cell cultures. Furthermore, the survival of T. gondii (RH strain)-infected mice increased from 2 days to 5 or more days. In a state of immunosuppression induced by methylprednisolone acetate, silk protein-administered mice were resistant to reduction in T-lymphocyte ($CD4^+$ and $CD8^+$ T-cells) numbers and the splenocyte proliferative capacity induced by Con A or TLA with a statistical significance. Taken together, our results suggest that silk protein augments immune capacity in mice and the increased cellular immunity by silk protein administration increases host protection against acute T. gondii infection.

Background: To compare ultrasound-guided pulsed radiofrequency (PRF) of the genicular nerve with the genicular nerve block using local anesthetic and steroid for management of osteoarthritis (OA) knee pain. Methods: Thirty patients with OA knee were randomly allocated to receive either ultrasound-guided PRF of the genicular nerve (PRF group) or nerve block with bupivacaine and methylprednisolone acetate (local anesthetic steroid [LAS] group). Verbal numeric rating scale (VNRS) and Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) scores were measured at pre-procedure and 1-, 4-, and 12-weeks post-procedure. Results: VNRS scores decreased significantly (P < 0.001) in both the groups at 12 weeks and other follow up times compared to baseline. Seventy-three percent of patients in the PRF group and 66% in the LAS group achieved effective pain relief (≥ 50% pain reduction) at 12 weeks (P > 0.999). There was also a statistically significant (P < 0.001) improvement in WOMAC scores in both groups at all follow up times. However, there was no intergroup difference in VNRS (P = 0.893) and WOMAC scores (P = 0.983). No complications were reported. Conclusions: Both ultrasound-guided PRF of the genicular nerve and blocks of genicular nerve with local anesthetic and a steroid provided comparable pain relief without any complications. However, PRF of the genicular nerve is a procedure that takes much more time and equipment than the genicular nerve block.

Background: Several therapeutic methods have been proposed for frozen shoulder syndrome. These include suprascapular nerve block, a simple and cost-effective technique that eliminates the need for nonsteroidal anti-inflammatory drug therapy. Methods: This was a clinical trial that included patients with unilateral shoulder joint stiffness. Patients were divided into three groups: those treated with isolated physiotherapy for 12 weeks (PT group), those treated with a single dose intra-articular injection of corticosteroid together with physiotherapy (IACI group), and those treated with a suprascapular nerve block performed with a single indirect injection of 8-mL lidocaine HCL 1% and 2 mL (80 mg) methylprednisolone acetate together with physiotherapy (SSNB group). The variables assessed were age, sex, side of involvement, dominant limb, presence of diabetes, physical examination findings including erythema, swelling, and muscle wasting; palpation and movement findings; shoulder pain and disability index (SPADI) score; and the visual analog scale (VAS) score pre-intervention and at 2-, 4-, 6-, and 12-week post-intervention. Results: Ninety-seven patients were included in this survey (34 cases in the PT group, 32 cases in the IACI group, and 31 cases in the SSNB group). Mean age was 48.55±11.06 years. Fifty-seven cases were female (58.8%) and 40 were male (41.2%). Sixty-eight patients had a history of diabetes (70.1%). VAS and SPADI scores and range of mototion degrees dramatically improved in all cases (p<0.001). Results were best in the SSNB group (p<0.001), and the IACI group showed better results than the PT group (p<0.001). Conclusions: Suprascapular nerve block is an effective therapy with long-term pain relief and increased mobility of the shoulder joint in patients with adhesive capsulitis.

3개월 령, 35kg의 수컷 볼조이가 간헐적인 좌측 전지 파행을 주 증상으로 내원 하였다. 1년 전 심한 운동 후 간헐적인 파행 및 동통을 호소하였으며, 증상은 계속 악화되었다. 신체 검사 상에서 좌측 두갈래근의 촉진과 견관절의 굴곡 및 신장 시에 통증을 호소하였다. 일반방사선 검사에서 좌측 견관절의 결절사이고랑에서 골증식체와 관절주위변성이 관찰되었다. 관절 조영상에서는 좌측 두갈래근 힘줄에 거칠고 불규칙한 영상을 확인할 수 있었다. 활액 검사 상에서는 퇴행성 관절 질환 소견이 보였다. 이상의 검사들을 바탕으로 두갈래근 힘줄 윤활막염으로도 진단하고, 내과적 치료를 실시하였다. 무균적으로methylprednisolone acetate 40mg을 관절낭 내로 주사하고, 3주간 엄격한 운동 제한을 실시하였다. 3주 후 내원 시 두갈래근 힘줄의 통증은 완전히 소실되었으나 퇴행성 관절염에 의한 경등도의 파행이 존재하여 NSAIDs의 투여를 실시하였다. 장기적인 예후의 관찰이 필요할 것으로 생각되며, 원발질환의 재발 시에는 2차 약물치료 또는 힘줄 절단술(힘줄 고정술, 힘줄박리술)등 을 통한 수술적인 치료가 고려될 수 있다.
