Premature ovarian failure (POF) is a condition in which the ovarian functions of hormone production and oocyte development become impaired before the typical age for menopause. POF and early menopause are present in a broad spectrum of gonad dysgenesis, from a complete cessation of ovarian function to an intermittent follicle maturation failure. Actually POF has been identified as a genetic entity (especially chromosome X), but data on genetic factors of premature menopause are limited. Until now, several cases revealed that inactivation of X chromosomes has an effect on ages of premature menopause and females with balanced or unbalanced X-autosome translocations can have several reproductive problems. On the other hand, there have been a few data that was caused by autosome-autosome translocation can lead. Therefore we report a relevant case of POF with translocation between chromosomes 1 and 4. She had her first menstrual period at the age of 12, and after 7 years she stopped menstruation. Chromosomal analysis showed 46, XX, t (1;4) (p22.3;q31.3). While evaluating this rare case, we could review various causes (especially genetic factors) of POF. To remind clinicians about this disease, we report a case of POF caused by autosomeautosome translocation with a literature review. (J Menopausal Med 2015;21:112-114)

N/A Korean hemorrhagic fever which was recognized for the first time in Korea near the Demilitarized Zone between North and South Korea in 1951 during Korea War have spread to the southern part of the Korean peninsula and several hundreds of cases are clinically and serologically diagnosed each year. However the Northern Part of Kyoung Ki Do is still remained as epidemic area. In recent years, we experienced 55 cases of Korean Hemorrhagic Fever in the northern part of Kyoung Ki Do during the period, 1984-1986, and we found different clinical patterns of Korean hemorrhagic fever from those reported earlier. Here we report the epidemiological and clinical observations with laboratory findings. 1) The disease was prevalent in adult male farmers and the epidemic seasons were fall and early winter. The epidemic areas of the disease are mainly Yang Ju, Yeoncheon and Pocheon. 2) Clinical pictures of Korean Hemorrhagic Fever were characterized by headache (76%), abdominal pain (69%), nausea & vomiting (67%), fever (56%) and myalgia & general aching (49%). 3) On physical examination, fever (56%), abdominal tenderness (36%), tachycardia (35%), hypotension (27%), petechia (24%), conjunctival injection (22%) and facial flushing and edema (16%) were found. 4) On laboratory examination, leukocytosis, thrombocytopenia, left shift of leukocyte, toxic granule, proteinuria, microscopic hematuria and increased specific gravity were found. Blood chemistry findings were characterized by increased BUN & creatinine, increased SGOT & SGPT, hyponatremia, increased LDH & FDP and hyperkalemia. 5) Clinical forms of typical hemorrhagic fever were as follows: Typical oliguric type 49%, typical nonoliguric type 21% and atypical type 29%. 6) Double infection to Leptospirosia was found in 8 cases.

Objective: Contrast-induced nephropathy (CIN) frequently occurs after percutaneous intervention. Objective of this study was to investigate the usefulness of serum cystatin C, neutrophil gelatinase-associated lipocalcin (NGAL), urinary kidney injury molecule-1 (KIM-1), and interleukin-18 (IL-18) as early predictors for CIN after percutaneous coronary intervention (PCI). Methods: In 53 patients who underwent PCI were enrolled. Serum creatinine and cystatin C level were measured immediately before, and 24 hours and 48 hours after catheterization. Serum NGAL, urinary KIM-1, and IL-18 were measured immediately before, and 4 hours, 24 hours, and 48 hours after catheterization. CIN was defined as a rise in creatinine 0.5 mg/dL or 25% above baseline. Results: CIN occurred in four patients (7.5%). Serum cystatin C levels were higher at 24 hours and 48 hours in CIN patients than in those without CIN (P<0.05). Serum NGAL levels were higher at 48 hours in CIN patients than in those without CIN. Urinary KIM-1 levels were higher at 48 hours in CIN patients than in those without CIN. There were no significant markers of CIN on multi-variate analysis. Conclusion: In this study, the occurrence of CIN after PCI was 7.5%. Although there were some time-course changes in serum cystatin C and urinary KIM-1 after PCI, there was no significant predictor for CIN after PCI.

김정민,권영준,주영수,임형준,이태경,강혜련,백도명 大韓産業醫學會 2008 대한직업환경의학회지 Vol.20 No.3

목적: 일개 제빵회사에서 제빵공 천식 유병률을 조사하여 제빵공 천식으로 인한 국내 질병부담을 파악하는데 기초자료를 제공하고자 하였다. 방법: 일개 제빵회사의 생산관련 근로자 596명에서 수습기간(3개월) 중이거나 참여를 거부한 216명을 제외하고,380명을 연구대상으로 하였다. 밀가루분진 노출형태에 따라 직접노출군과 간접노출군으로 직무 카테고리를 분류하고,설문조사는 ISAAC 설문항목에 직업력 등을 추가한 설문지를 사용하였다. 설문조사에서 천식이나 알레르기병과 관련된 증상이나 병력이 전혀 없는 간접노출군은 임상검사대상에서 제외하였다. 임상검사대상 233명에게 피부단자검사,혈청 특이 IgE 항체검사,산업의학 전문의와의 면담을 시행하였고,면담에서 천식이나 알레르기비염과 관련된 증상이나 병력이 확인된 31명을 연속적 PEFR 측정대상으로 하였다. PEFR 변동률로써 메타콜린 기관지유발검사대상을 선정하였고,메타콜린 기관 지유발검사에서 기관지과민성이 확인된 경우에 특이 기관지유발검사를 시행하였다. 제빵공 천식은 특이 기관지유 발검사에서 천식반응이 확인된 경우로 정의하였다. 결과: 연구대상의 밀가루 민감화율은 21.0%(직접노출군 25.9%,간접노출군 13.3%), 제빵공 천식 유병률은 3.2%(직접노출군 5.1%,간접노출군 1.8%)였다. 직접 노출군이 간접노출군에 비해 밀가루에 민감화될 위험이 높았으며(OR 2.15,95% CI=1.03∼4.51), 제빵공 천식에 이환될 위험은 통계적으로 유의하지 않았다(PR 2.52,95% CI=O.78∼8.18). 밀가루에 민감화된 군이 그렇지 않은 군에 비해 제빵공 천식에 이환될 위험이 매우 높았다(PR 38.63, 95% CI=6.14∼243.22). 결론: 이번 연구결과는 직업적으로 밀가루에 노출되는 국내 근로자에서 제빵공 천식이 적지 않을 것임을 시사하고 있다. 향후 제빵공 천식으로 인한 질병부담을 보다 정확히 파악하기 위해서는 국내에서 연구된 바 없는 밀가루 취급 사업장(제분회사 등)에 대한 연구가 필요하며,근로자의 건강과 사회경제적 위치를 보호하기 위한 체계적인 연구도 요구된다. Objectives: To determine the prevalence of baker's asthma due to flour dust in an industrial bakery in Korea. Methods: Of the 596 active workers, 380 were allocated to a category of either direct exposure (DE) or indirect exposure (IE) to flour dust and completed a modified ISAAC questionnaire. Of the 380 participants, 233 were screened by an occupational physician interview, a skin prick test, and an ELISA for serum-specific IgE antibodies to wheat flour extracts. Selected workers received serial monitoring of peak expiratory flow rate (PEFR), and positive PEFR respondents received a methacholine challenge test. The diagnosis of baker's asthma was confirmed by a specific inhalation challenge with wheat flour extracts. Results: The prevalence of sensitization to wheat flour and baker's asthma was 21.0% (25.9% DE, 13.3% IE) and 3.2% (5.1 % DE, 1.8% IE), respectively. DE had an increased risk of sensitization to wheat flour (OR 2.15, 95% CI = 1.03∼4.51). Sensitization to wheat flour and the prevalence of baker's asthma correlated significantly (PR 38.63, 95% CI = 6.14∼243.22). Conclusions: These findings indicate a considerable prevalence of baker's asthma among flour-exposed workers in Korea. Future studies will be required to survey the situation in flour mill companies and seek ways to protect the health and socioeconomic position of flour industry workers.

An agar degrading bacteria was isolated from the south ocean of Korea and was identified as Aeromonas sp. This strain produced the amount of agarase (1.4U/ml) with agar as a carbon source and casamino acid as a nitrogen source. The optimum concentration of NaCl for both cell growth and enzyme activity was 2.5%. The agarase was purified by DEAE-cellulose and hydroxyapatite column chro-matograpy. The purified agarase showed a single protein band upon sodium dodecyl sulfate-polyacrylamide gel electrophoresis(SDS-PAGE) and its molecular weight was estimated to be 50 KDa. The optimal temperature and pH for the enzyme activity were 28℃ and 7.2, respectively. The agarase was stable at pH 6.5 - 8 and 22 - 37℃. The agarase activity was notably inhibited by EDTA, Mn2+, Hg2+, Fe2+ and slightly activated by Na+ and Ba2+.

The lightweight aggregate was artificially pelletized, with use of fly ash, obtained from coal power plant, and waste glass wool as a flux, by sintering process in electrical muffle furnace. Those were fired at 1,000℃ and 1,100℃ for 3 and 6 minutes respectively. IDT(Initial Deformation Temperature) of fly ash, was appeared 1,360℃, but fly ash, when mixed with 50wt% of waste glass wool and 5wt% borax as fluxes, came into 1,156℃. Absorption ratios of sintered pellets for 24hrs had the lower values in the range of 4.3 to 6.3% than 16.8% of ILA(imported lightweight aggregate). Increasing of sintering temperature and time, absolute dry specific gravity of sintered pellet tended upward. Absolute dry specific gravity of pellet sintered at 1,000℃ for 3 minutes was 1.36 and this value was similar to that of ILA. SEM showed that the fractured surface of pellet, sintered at 1,000℃, had more fused phases in outer region rather than inner. It was shown, however, that the pellet, sintered at total pore surface was increased because large pores transfer into small pores by increasing sintering temperature.
