목 적: 근시를 가진 굴절교정수술을 받은 환자를 대상으로 수술 전후 나타나는 조절력, 사위도, 입체시 등의 양안시기능 변화를 3개월간 추적 관찰하였다. 방 법: 근시안의 굴절교정수술을 받은 20대 50명(남자 23명, 여자 27명)을 대상으로 굴절교정수술 전과 수술 후(1주일, 1개월, 3개월)의 굴절검사 및 조절력검사(Push-up method), 원근거리 사위도(Howell 시표 에 의한 3 m, 33 cm검사), 입체시검사(Titmus 입체시표) 등을 조사하였다. 결 과: 굴절교정 수술 전의 굴절검사 값은 -4.96±2.17D이었고, 수술 3개월 후 굴절검사 값은 -0.54±0.44D 이었다. 굴절수술 전의 조절력은 9.85±2.29D이었으며, 수술 후 1주일, 1개월, 3개월의 조절 력 값은 각각 7.85±2.05D, 7.99±1.81D, 9.16±2.01D로 측정되었으며, 수술 1주일 후 조절력이 떨어졌다 가 3개월 후 다시 증가하는 양상을 나타내었다(F=21.83, p<0.001). 굴절교정 수술 전 원거리 사위도는 -0.03±1.96△, 수술 3개월 후 사위도는 0.15±1.96△로 측정되었으며, 수술 전 근거리 사위도는 -0.54±1.61△, 수술 3개월 후 사위도는 -0.46±1.60△로 측정되었다. 수술 전과 후의 원, 근거리 사위도 는 수술 전과 비교하여 통계적으로 유의하지 않았다. 입체시 값은 굴절교정 수술 전이 52.40±12.70초, 수 술 후 1주일 값이 63.00±14.74초, 수술 후 1개월 값이 60.00±12.94초, 3개월 값이 52.80±12.13초로 측정 되었다(F=8.06, p<0.001). 결 론: 근시 굴절교정수술을 받은 환자를 대상으로 양안시 변화를 분석한 결과 수술 전과 비교하여 조절 력은 수술 후 1주일, 1개월, 3개월동안 통계적으로 유의하게 감소하였다. 그러나 3개월 이후 조절력은 회복되 는 양상을 보였다. 입체시는 수술 후 1 주일, 1개월은 통계적으로 유의하게 증가 하였고 3개월 후에는 수술 전 상태로 유의하게 회복하였다. Purpose: With myopic refractive surgery patients who received preoperative amplitude of accommodation, phoria degree, binocular stereopsis, and functional changes were followed for 3 months. Methods: Myopic refractive surgery in twenties of 50 people(23 males, 27 females) to target refractive surgery before and after surgery(1week, 1month, 3months) and the amplitude of accommodation test(Push-up method), the phoria test of far and near(Howell by chart for 3 m, 33 cm test), stereo-acuity test(Titmus steropsis chart) were evaluated. Results: Refraction before refractive surgery were the value -4.96±2.17D, three months after surgery refractions were the value -0.54±0.44D. Accommodation before refractive surgery were the 9.85±2.29D after surgery, 1week, 1month and 3months respectively accommodation 7.85±2.05D, 7.99±1.81D, 9.16±2.01D measured, and a week after surgery fell accommodation, the pattern shown to increase again after three months(F=21.83, p<0.001). The far phoria of before refractive surgery were -0.03±1.96△, three months after surgery the far phoria were measured to be 0.15±1.96△, also the near phoria before surgery ranged -0.54±1.61△, the near phoria were measured to be -0.46±1.60△, three months after surgery. Before and after surgery, compared to the surgery before the far and near phoria were not statistically significant. The value of stereo-acuity before refractive surgery were measured to be 52.40±12.70 sec, a week after surgery were 63.00±14.74sec, the value of one month after surgery 60.00±12.94 sec, the values of three month ere measured to 52.80±12.13 sec(F=8.06, p<0.001). Conclusions: With myopic refractive surgery patients who received preoperative analysis of the change of the accommodation and stereo-acuity a week after surgery and then increased again after 3 months to reduce pattern could be observed.

Tranexamic Acid-Induced Acute Renal Cortical Necrosis in Post-Endoscopic Papillectomy Bleeding

고두현,김태형,김종욱,Ja Joong Gu,윤백현,오지홍,홍승권 대한소화기내시경학회 2017 Clinical Endoscopy Vol.50 No.6

Acute renal failure can be the result of acute renal cortical necrosis (RCN), which commonly occurs from complications occurring during pregnancy. RCN is rarely caused by medications, although tranexamic acid, which is used in patients with acute bleeding for its antifibrinolytic effects, reportedly causes acute RCN in rare cases. An 82-year-old woman experienced gastrointestinal bleeding after endoscopic papillectomy of an ampullary adenoma. The bleeding was controlled with tranexamic acid administration; however, 4 days later, her urine volume decreased and she developed pulmonary edema and dyspnea. Serum creatinine levels increased from 0.8 to 3.9 mg/dL and dialysis was performed. Abdominal pelvic computed tomography with contrast enhancement revealed bilateral RCN with no renal cortex enhancement. Renal dysfunction and oliguria persisted and hemodialysis was continued. Clinicians must be aware that acute RCN can occur after tranexamic acid administration to control bleeding.

Simultaneous multi-vessel acute myocardial infarction is rare and has poor prognosis. We report a 70-year-old Korean man with an anteroseptal wall ST-elevation myocardial infarction presenting as ventricular tachycardia, sudden cardiac arrest and cardiogenic shock. After successful cardiopulmonary resuscitation, a coronary angiogram revealed three-vessel coronary disease; simultaneous total occlusions of the proximal left anterior descending artery (LAD) and the proximal left circumflex artery (LCX), and chronic total occlusion of the proximal right coronary artery. Primary percutaneous coronary intervention (PCI) of the LAD and LCX was successful and an intra-aortic balloon pump was inserted. Despite the timely and successful PCI result, he died on the 58th day in the hospital due to pneumonia with multiple organ failure.

Catalytic Transesterifications by a Zn–BisSalen MOF Containing Open Pyridyl Groups Inside 1D Channels

<P><B>Abstract</B></P><P>The new ligand <I>N</I>,<I>N′</I>,<I>N″</I>,<I>N″′</I>‐tetrakis[3‐<I>tert</I>‐butyl‐5‐(4‐pyridinyl)salicylidene]‐1,2,4,5‐benzenetetraamine (bisSalen) containing four pyridyl groups in its periphery was prepared and subsequently used as an organic linker for a Zn–bisSalen MOF. A 2D undulated sheet structure was determined from single‐crystal X‐ray diffraction studies. The bisSalen ligands bridge two Zn<SUP>II</SUP> ions, and one of the pyridyl groups on each side of the bisSalen ligand further coordinates to a bisSalen‐coordinated Zn<SUP>II</SUP> ion to provide a 2D sheet structure. The undulated 2D sheets are stacked closely together to form a 3D‐like structure containing well‐defined 1D channels, the orientation of which is perpendicular to the 2D sheets. The geometry of the bisSalen in the MOF is not planar. The remaining uncoordinated pyridyl groups point toward the 1D channels. Because of these openly accessible pyridyl groups in the channels, the Zn–bisSalen MOF is a very active catalyst for transesterifications.</P>

Human toxocariasis is a common helminthozoonosis due to the infestation of toxocara canis or toxocara cati larvae, and is a common cause of blood eosinophilia in Korea. Toxocariasis has various clinical manifestations depending on the involved organ, and cardiac involvement can range from asymptomatic to fulminant myocarditis with cardiogenic shock. Treatment of toxocariasis is based on corticosteroid and anthelmintic therapies. Here, we report a case of a 57-year-old male with eosinophilic myocarditis caused by toxocariasis as diagnosed via serial echocardiography follow up. (Korean J Med 2018;93:482-486)

1.5wt% TEMPO 산화 나노셀룰로오스 (TONC)를 0.1, 1.0, 10ml/ml 속도로 acetone에 방사하여 습식방사섬유를 제조하였다. 제조된 방사섬유를 0.1, 1.0, 3.0mM AgNO3에 침지시킨 후, 15min 동안 UV를 조사하여 섬유표면의 Ag⁺를 Ag⁰로 환원하였다. 방사속도와 방사용액의 농도가 감소할수록 방사섬유내 TOCNF의 배향성이 향상되었다. 습식방사섬유는 약 200 um 내외의 직경을 지니고 있으며, 방사속도가 증가할수록 직경이 감소하는 경향을 보였다. 또한, 방사속도 0.1ml/min에서 10ml/min로 증가함에 따라, orientation index가 0.64에서 0.70으로 증가하였으며, 인장강도 및 탄성계수 또한 증가하였다. AgNO₃농도가 증가할수록 방사섬유에 합성된 AgNP의 함량이 증가하였으며, AgNP의 함량이 증가할수록 방사섬유의 인장강도와 탄성계수가 향상되었다.
