본 연구는 알킬 페놀류 8종(4-t-butyl phenol (BP), 4-n-pentyl phenol (PP), 4-n-hexyl phenol (HxP), 4-t-octyl phenol (t-OP), 4-n-heptyl phenol (HpP), b-nonyl phenol (b-NP). 4-n-octyl phenol (OP), 4-n-nonyl phenol (NP))을 액체 크로마토그래피(HPLC) 다이오드 배열 검출기(diode array detector, DAD)를 이용하여 동시분석하였다. 분리관은 역상 Cl8(250×4.6 mm), 이동상은 물과 메탄올을 사용하여 기울기 용리(gradient)하에서 알킬 페놀류의 알킬 길이에 따라 분리하였으며, 알킬 페놀류의 검량선을 도시한 결과 좋은 직선성이 보였다. 상기 분석법으로 국내 유통 중인 주방 세제류 내 알킬 패놀류를 분석한 결과 불검출 되었고, 이때 검출한계는 주입량(10 μL) 대비 1 pg이었다. 4-t-butyl phenol (BP), 4-n-pentyl phenol (PP), 4-n-hexyl phenol (HxP), 4-1-octyl phenol (t-OP), 4-n-heptyl phenol (HpP), b-nonyl phenol (b-NP), 4-n-octyl phenol (OP), and 4-n-nonyl phenol (NP) were simultaneously separated by a high performance liquid chromatography (HPLC) with UV diode array detector(230 nm, f60 nm, 280 nm) using an octadecylsilica column (Cl8, 250×4.6 mm) and water/methanol gradient solution. The calibration curves of alkyl phenols showed a good linear relationship, and the recoveries were over 95%. With the detection limit of 1pg for alkyl phenols with respect to the injected amount, alkyl phenols were not detected in tile dishwashing detergents that were available on the market.

Isolated anomalous right coronary artery originating from the pulmonary artery (ARCAPA) is a rare congenital coronary anomaly that is asymptomatic and discovered incidentally in most cases. ARCAPA is generally not considered a fatal defect in infancy or childhood, although cases of sudden death have been reported. Here, we report a 2-month-old female infant who presented with a prolonged fever that was determined to be caused by rhinovirus infection. Myocardial ischemia of the left ventricular posterior wall was already seen on echocardiography, and ARCAPA was discovered incidentally. The patient underwent successful surgical reimplantation of the right coronary artery to the aortic root to re-establish dual ostial circulation.
