부신피질 자극호르몬 단독결핍은 국내에서 7례만이 보고된 희귀 질환이며 병인 및 경과 등 아직 불분명한 측면이 많다. 이는 질환지체의 희귀성도 있지만 치료후 자연경과에 대한 장기적인 추적검사가 이루어진 경우가 드물기 때문이기도 하다. 저자들은 비특이적인 전신증상을 주소로 내원한 폐경기후의 56세 여자 환자에서 자가면역질환의 증거없이 고프로릭틴혈증을 보인 부신피질 자극호르몬 단독결핍 1례를 경험하고 1년간의 부신피질호르몬 대치요법후 추적검사를 실시하였기에 문헌 고찰과 함께 보고하는 바이다. Isolated ACTH deficiency is a rare disorder which shows secondary adrenal insufficiency with normal states of other pituitary hormones. A 56-year-old postmenopausal woman complaining general weakness and intermittent mental confusion presented negligible serum cortisol and ACTH level with hyperprolactinemia and mild hyponatremia. Rapid ACTH stimulation test did not show significant increase of serum cortisol level. Combined pituitary stimulation test showed negligible response of cortisol and ACTH, and slightly decreased response of prolactin and gonadotropin. But the responses of TSH and GH were normal. There was no evidence of organic pituitary of hypothalamic lesion in brain MRI and antithyroid autoantibody was not detected in serum. After receiving 12 months of glucocorticoid replacement therapy, she skipped the medicine for 3 weeks and we performed follow-up endocrinologic tests. Serum ACTH and cortisol level was also negligible and prolonged ACTH simulation test showed normal response of serum cortisol. CRF stimulation test showed no response of serum ACTH. Basal prolactin level was decreased to near normal and combined pituitary stimulation test showed normal response of prolactin with slightly blunted response of TSH and GH. We concluded that the case was nonautoimmune origined isolated ACTH deficiency which was accompanied by hyperprolactinemia and resultant deficiency of gonadotropin, so we report this case with review of literatures.

<P>This study compared the efficacy of DA-9601 (Dong-A ST Co., Seoul, Korea) and its new formulation, DA-5204 (Dong-A ST Co.), for treating erosive gastritis. This phase III, randomized, multicenter, double-blind, non-inferiority trial randomly assigned 434 patients with endoscopically proven gastric mucosal erosions into two groups: DA-9601 3 times daily or DA-5,204 twice daily for 2 weeks. The final analysis included 421 patients (DA-5204, 209; DA-9601, 212). The primary endpoint (rate of effective gastric erosion healing) and secondary endpoints (cure rate of endoscopic erosion and gastrointestinal [GI] symptom relief) were assessed using endoscopy after the treatment. Drug-related adverse events (AEs), including GI symptoms, were also compared. At week 2, gastric healing rates with DA-5204 and DA-9601 were 42.1% (88/209) and 42.5% (90/212), respectively. The difference between the groups was −0.4% (95% confidence interval, −9.8% to 9.1%), which was above the non-inferiority margin of −14%. The cure rate of gastric erosion in both groups was 37.3%. The improvement rates of GI symptoms with DA-5204 and DA-9601 were 40.4% and 40.8%, respectively. There were no statistically significant differences between the two groups in both secondary endpoints. AEs were reported in 18 (8.4%) patients in the DA-5204 group and 19 (8.8%) in the DA-9601 group. Rates of AE were not different between the two groups. No serious AE or adverse drug reaction (ADR) occurred. These results demonstrate the non-inferiority of DA-5204 compared to DA-9601. DA-5204 is as effective as DA-9601 in the treatment of erosive gastritis. Registered randomized clinical trial at ClinicalTrials.gov (NCT02282670)</P>

Background: The outcome of hepatitis B virus (HBV) infection after liver transplantation (LT) was improved by hepatitis B immunoglobulin (HBIG) and nucles(t)ide analogue (NUA). However, HBV recurrence after LT is critical because the recurrence is occasionally accompanied by a progressive destruction of graft and poor survival. The aims of this study were to investigate the significance HBV recurrence and identity factors associated with HBV recurrence. Methods: From October 1999 to February 2011, a total of 2684 consecutive LT recipients who underwent HBV-associated LT were retrospectively enrolled from 7 transplantation centers in Korea. Results: Prophylaxis regimens were HBIG monotherapy (67.7%) or a combination of HBIG with NUA (22.3%). The recurrence rate of HBV was 6.1% (164 recipients) during mean follow-up duration of 10.9 years. The median time from transplantation to recurrence was 2.1 years (0.1-7.9 years). Of the 1,071 patients with hepatocellular carcinoma (HCC) prior to LT, 155 patients (14.5%) had HCC recurrence after transplantation, and 48 patients (31.0%) had HBV recurrence. Of the 48 patients with recurrence of both HBV and HCC, 25 patients (52.1%) experienced HBV recurrence after HCC recurrence. In the multivariate analysis, pretransplant HCC, pretransplant HBV DNA above 5.5 log copies/mL was independent clinical factors influencing HBV recurrence after LT. The mortality rate among the recipients with HBV recurrence was 34.1% (56 recipients). Mean overall survival was 6.4 years in the HBV-recurrence group and 9.9 years in the HBV-nonrecurrence group (p<0.001). HBV recurrence was not an independent prognostic factor for overall survival. HCC recurrence was the most important factor for overall survival. Conclusions: The overall outcome of LT in HBV-related liver disease was excellent with the current prophylaxis regimen Choon Hyuck David Kwon,8 Suk-Koo Lee8 Pretransplant HBV DNA and HCC were important factors for HBV recurrence. HBV recurrence after LT did not significantly influence on the overall survival without combining of HCC recurrence.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

N/A 131I-6β-iodomethyl-19-norcholesterol(NP-59) has an advantage to assess adrenal dysfunction caused by adrenal cortical disorders. The aim of this study is to evaluate the clinical usefulness of NP-59 scintigraphy in each adrenral disease. Ten patients who did eleven NP-59 adrenal scintigraphies at Dong-A University Hospital from March 1990 to December 1996 were selected as the subject. Among the subject there were 5 cases of Cushing's syndrome, 2 cases of incidentaloma, 1 case of metastatic adrenal tumor, liver cirrhosis with hirsutism and hypertension respectively. Among 5 case of Cushing's syndrome, there were 2 cases of Cushing's disease, 2 cases of adrenal adenoma and 1 case of adrenal carcinoma. There are no disagreement between clinical diagnosis and scan finding in Cushing's syndrome. In 2 incidentaloma cases, even though one is interpretated as a functioning tumor, both of 2 cases could avoid unnecessary biopsy according to scintigraphy result. One case of hirsutism, clinically adrenal originated, revealed the normal scintigraphic hirsutism was extra-adrenal origin. One case of hypertension took the study to exclude the possibility of primary aldosteronism. Normal suppression scan finding revealed that primary aldosteronism did not exist in this case. In conclusion, NP-59 scintigraphy was very useful in diagnosis and differential diagnosis of Cushing's syndrome and it could avoid unnecessary biopsy in the incidental adrenal tumor.

이동규,강선철 대구대학교 (한사대학) 산업기술연구소 1994 産業技術硏究 Vol.13 No.-

Micrococcus sedentarius KL-37, an alkalophilic bacterium isolated from soil, produces and secretes at least three distinct proteases to the growth medium. Two of them, protease I and II, characterized in more details for their enzymatic properties were homogeneously purified through ammonium sulfate fractionation and CM-cellulose column chromatography but the other, protease III, was only partially purified even after a further purification step like DEAE-cellulo column chromatography. The molecular weights of protease Iandd II were 35,000 and 14,000 daltons, respectively, being judeged by SDS-PAGE. The enzymes revealed their maximum activities at pH 11l0 and 40℃, and were completely inactivated by PMSF and EDTA withil serine-metallo protease. And the effects of divalent ions on hese enzymes showed that the enzyme were activates by Mg_(++), Ca_(++) and Co_(++), while completely inactivated by Fe_(++), in the 10mM concentration of those ion.

The disabled has remarkable difficulties to participate social activities and those, that block them up from access to public facilities and the comfortable habitation so they should get help from others, are mainly made by architectural facts. Buildings without impediment which consider the disabled would be the things responding to the needs of the times. If the disabled would be convenient to use facilities, there should be no difficulties to normal people. A first began to examine into the role of the architecture. And to establish radical standards for the disabled to use cultural and assembly facilities through scrutinizing facilities to get access for the disabled and movement circulations in the cultural facilities should be the conclusion. This study which is a kind of fundamental study to construct cultural facilities without obstacles for the disabled began from consideration for the problem flow line of the disabled in cultural facilities and analyzed flow lines for them to use, access, and evacuate from those which are main facilities in the region. Though, evacuation rules in cultural and assembly facilities are recommendatory in existing laws for convenience of the disabled, the congestion of the crowd coming out after performances impedes safe flows of both the disabled and crowds. Further, in case of evacuation, there would be more serious problems. Therefore, consideration of reinforcement for existing laws for convenience of the disabled is needed.
