The objective of this study is to investigate the effect of Al addition on the reaction behavior of cobalt with molten zinc. Pure cobalt specimen was immersion tested in the three kinds of molten zinc (pure, 0.12%Al added and 0.24%Al added) baths at 460℃, 490℃ and 520℃. For the understanding of degradation processes, specimens were analyzed with scanning electron microscope (SEM) and energy dispersive spectrum (EDS), and electrochemical stripping method. When 0.12% and 0.24% Al was added in molten zinc baths, three intermetallic compounds layers of γ, γ1, and γ2 were formed on the Co matrix and β1 layer was not formed between the Co matrix and the γ layer. Particles of CoAl intermetallic compound were formed at the interface between the γ2 layer and zinc melt and they did not adhere to the Co-Zn intermetallic layer. Weight loss of the Co specimen increased as Al content in the molten zinc increased and the relationship of weight loss vs. immersion time followed parabolic rate law. Rate controlling process for the reaction rate of Co with Al added molten zinc was analyzed as the diffusion process of Al atom through a boundary layer between the γ2 layer and the Al added zinc melt.

Objectives: This study was carried out to provide safe seafood to the public through simultaneous analysis rapid inspections for residual veterinary drugs in 150 fishery products in 2016. Methods: Quinolones (9), Sulfonamides (14), Penicillins (2), Cephalosporins (3), Tetracyclines (4), Macrolides (4), Lincosamides (2), Pleuromutilin (1), Phenicols (4), benzylpyrimidines (2), Others (1) Malachite green (2), and Melamine (1) were analyzed for 49 species using by HPLC and HPLC-MSMS. Results: There were six unsuitable samples, five among fish and one for crustaceans. Within the standard detection were five fish. The antibiotics found were Quinolones (50%), Tetracyclines (33%) and Penicillins (17%). Conclusions: As a result of the experiment, there were six unsuitable samples, five for fish and one for crustaceans. The most prevalent antibiotics were Quinolones. The quinolone antibiotics are highly persistent in fish tissues, so they require more time than the withdrawal period for other common veterinary drugs. Careful attention is required when they are used in fish farms.

Continuous ambulatory peritoneal dialysis(CAPD) is now the most important and effective therapeutic modality as well as hemodialysis(HD) and renal transplantation in patients with chronic renal failure. It is frequently recommended to diabetic renal failure patients because of poor, athersclerotic vascularity of them. Hyperglycemia and obesity are not uncommon complications of CAPD therapy. But there were only few reports of very severe hyperglycemia or hyperosmolar coma in CRF patients on CAPD therapy, especially with 7% dextrose CAPD dialysate in foreign countries in the past. Moreover, no specific management for hyperosmolar coma is established in those situations yet. In Korea, only three cases of hyperosmolar coma in non diabetic renal failure patient on CAPD therapy have been reported in one case report. And only one case among them whose CAPD therapy was changed to HD survived. Authors also experienced a case of diabetic hyperosmolar coma treated successfully with conversion to HD in chronic renal failure patient on CAPD therapy. So we report this case with a review of literature. Taken together with this case and review of literature, changing CAPD therapy to HD is regarded to be an important part of treatment when hyperosmolar coma develops in chronic renal failure patients.

Primary biliary cirrhosis(PBC) is a disease of unknown etiology characterized by the destruction of small intrahepatic bile ducts, probably on an immunologic basis. PBC affects mainly middle aged women, and cause cholestasis that may progress to cirrhosis and finally result in the liver failure. We report a case of 39-year-old woman with a initial presentation of general weakness and pruritus for 5 years. Liver biopsy findings were compatible with PBC showing monocyte infiltration, destruction of srnall intrahepatic bile ducts, and periportal fibrosis that were accompanied by negative anti-mitochondrial antibody in repeated tests.

Background: Idiopathic Central Diabetes Insipidus in children or adolescents requires a frequent follow-up regimen using serial brain MRI and CSF examinations especially if an isolated pituitary stalk thickening or loss of a hyperintense signal in the posterior pituitary lobe is observed. Although a detailed description has not been made in adults who had Idiopathic Central Diabetes Insipidus, the clinical course of a Central Diabetes Insipidus in children or in adolescents can not be applied to adults because a follow-up study is so invasive and expensive. In this report, we evaluated the clinical course of Idiopathic Central Diabetes Insipidus in adults. Methods: The diagnosis of Idiopathic Central Diabetes Insipidus was based on the presenting clinical symptoms, the water deprivation test, biochemical studies and a brain MRI. We measured the urine specific gravity, urine and plasma osmolarity, electrolytes, and daily urine amount and we also performed an anterior pituitary evaluation. Patients had contrast-enhanced MRI and biochemical studies every 4 to 12 months. Results: The patients included 8 females and 4 males. Their ages ranged from 20 to 76 years and their mean age was 45±17 years. Tumor markers in the CSF were not detected any of the patients. An anterior pituitary evaluation showed that four patients had hyperprolactinemia, and five patients had impaired secretory responses of Growth Hormone to an insulin induced hypoglycemia. Nine of the 12 patients had thickening of the pituitary stalk, seven had lacked the hyperintense signal of a normal neurohypophysis. The abnormalities of MRI disappeared in 3 patients by the 4th, 27th and 36th month follow up periods, respectively. The follow up duration was between 8 months and 11 years 3 months and the mean follow up duration period was 50.6±45.5 months. Clinical symptoms were corrected by DDAVP administration. Other symptoms were absent. Conclusion: In our study, of Idiopathic Central Diabetes Insipidus in adults there were no observed germinomas or other disease that were observed. Therefore this disorder may have a benign course

연구배경: 중추성 부신피질 기능저하증 환자에서 적절한 당류코르티코이드의 보충용량을 결정하는 것은 과다치료에 의한 부작용을 피하고 환자의 증상을 호전시키기 위하여 매우 중요하다. 본 연구는 중추성부신피질 기능저하증 환자에서 당류코르티코이드 보충요법을 결정하는데 있어 부신피질 기능검사의 임상적 유용성을 평가하고 적절한 보충용량을 결정하기 위하여 이루어졌다. 방법: 인슐린 유발 저혈당 검사로 중추성 부신피질 기능저하증이 확인된 환자 40명을 대상으로 기저 코르티졸 검사, 250 g 급속 ACTH 자극검사와 인슐린 유발 저혈당 검사를 시행하였고 당류코르티코이드 복용을 결정하는데 이 검사들의 유용성을 평가하였다. 또한 중추성 부신피질 기능저하증상으로 당류코르티코이드를 복용중인 26명을 대상으로 당류코르티코이드 의 용량을 3개월마다 5 mg, 3.75 mg, 6.25 mg으로 변화시키고 용량 변화 전후에 혈중 지질과 생화학적 골표지자를 측정하였다. 결과: 1) 기저 코르티졸치와 인슐린 유발 저혈당검사 및 급속 ACTH 자극검사에서 최대 코르티졸치가 당류코르티코이드 보충요법 결정에 95%의 특이도를 나타내는 경우 그 기준치는 각각 5 g/dL, 11 g/dL, 16 g/dL 미만이었고 이 때의 민감도는 각각 88.4%, 80.7%, 76.9%였다. 2) 당류코르티코이드 보충용량이 하루 6.25 mg으로 증량하였을 때 혈중 총 콜레스테롤, 저밀도 지단백 콜레스테롤, 고밀도 지단백 콜레스테롤 및 요중 N-telopeptide는 증가하였고 혈청 osteocalcin은 감소하였다. 특히 저밀도 지단백 콜레스테롤은 하루 5 mg에서 3.75 mg으로 용량을 변경하였을 때도 유의한 감소를 보였다. 결론: 중추성 부신피질 기능저하증 환자에서 당류코르티코이드 보충요법을 결정하는데 있어 환자의 증상 외에 기저 코르티졸치와 HPA 축 검사가 도움을 줄수 있으며 이 때 적절한 보충용량은 5 mg을 넘지 않는것이 적절할 것으로 생각된다. Background: Determination of the adequate dose of glucocorticoid replacement therapy, in patients with secondary adrenal insufficiency, is of great importance to avoid the consequences of under or over treatment. The aims of this study were: 1) to assess the value of adrenal cortical function tests in determining whether glucocorticoid replacement should be given, and 2) to investigate the adequate maintenance dose of glucocorticoid in patients with secondary adrenal insufficiency. Methods: Forty patients, with secondary adrenal insufficiency, confirmed by the insulin-induced hypoglycemia test (IHT), were studied. All subjects underwent basal serum cortisol measurement, IHT and 250 g rapid ACTH stimulation tests (AST). The clinical usefulness of these tests, for the determination of glucocorticoid replacement therapy, was evaluated in patients with secondary adrenal insufficiency. 26 of the 40 patients had received prednisolone (Pd) (5 mg per day) replacement due to symptoms from adrenal insufficiency. The dose of Pd was serially changed from to 3.75, and then to 6.25 mg per day, every 3 month. The measured lipid parameters, serum osteocalcin and urinary N-telopeptide were measured and the quality of life evaluated by the administration of an Addisonian questionnaire, both before and after the dose changes. Results: 1) For all tests, cut-offs were selected that would provide adequate specificity and sensitivity. When the cut-offs were set to provide 95% specificity, the corresponding sensitivity cut-off values, obtained with basal serum cortisol, peak serum cortisol in IHT and AST were: 88.4% <5 g/dL, 80.7% <11 g/dL and 76.9% <16 g/dL. 2) The urinary type I collagen N-telopeptide, total cholesterol, HDL- and LDL-cholesterol levels were significantly increased, and the serum osteocalcin levels significantly decreased when the daily dose of Pd was increased to 6.25 from 3.75 or 5 mg. The LDL-cholesterol levels especially, were significantly increased, even though the change in the Pd from 3.75 to 5 mg per day was subtle. Conclusion: The basal cortisol levels, HPA axis tests and the symptoms of patients may be helpful to determine whether prednisolone replacement therapy should be given. It is suggest that an adequate dose of glucocorticoid replacement therapy should be not exceed Pd 5mg per day, so as not to have adverse effects on the bone and lipid metabolisms (J Kor Soc Endocrinol 18:456∼464, 2003).
