Identification of a Calcium-activated Potassium Channel Gene Expressed in Rat Cardiac Myocytes
In Seung Park, Hyun-Kyu Jeon, Nam Su Kim, Youn Mo Ahn, Chul-Seung Park, Ha Baik

Purpose : Calcium-activated potassium channels(KCa) may be involved in the transient outward current of the first phase of cardiac action potential. But it is still not clear whether cardiac myocytes express any KCa. We try to identify here the types of KCa expressed in rat caridac myocytes. Methods : We isolated total heart RNA from 50 rats(Spague-Dawley) and performed reverse transcription-polymerase chain reaction(RT-PCR) using specifically...
Clinical and Epidemiologic Studies on Childhood Asthma.
Youn Mo Ahn, Sun Ho Lee, Ha Baik Lee, Hahng Lee
Clin Exp Pediatr. 1990;33(5):632-641.   Published online May 31, 1990
The one-hundred-twenty-seven asthmatic children who were diagnosed and treated either through admission or through clinic visits at the Department of Pediatrics, Hanyang University Hospital from July 1987 to March 1989, were investigated for clinical patterns and epidemiologic correlations. The diagnosis of asthma was made by typical clinical history, physical findings and laboratory examina- tion. The results were as follows: 1) Sixty-three percent of the total population at...
An Agiographic Study on Developemental and Spatial Relationship of Patent Ductus Arteriosus (PDA) and Aortic Arch in Right Ventricular Outflow Tract (RVOT) Obstruction.
DO Hyun Kim, Youn Mo Ahn, Ha Balk Lee, Kyoo Hwan Rhee, Hahng Lee, Seok Chol Jeon
Clin Exp Pediatr. 1988;31(9):1139-1145.   Published online September 30, 1988
Ductus arteriosus plays important hemodynamic role in fetal development, and establish a certain spatial relationship with aorta. Although ductus arteriosus normally closes after birth, it could remain patent alone, or in association with various congenital heart anomalies. In these patients the develop- mental hemodynamic changes may result in the specific variation in the spatial relationhip of patent ductus arterisus (PDA) and aortic arch. The developmental...
A Clinical Study of Hospitalized Neonates with Fever.
Youn Mo Ahn, Chang Ryul Kim, Woo Gill Lee, Soo Jee Moon
Clin Exp Pediatr. 1988;31(11):1437-1444.   Published online November 30, 1988
Life-threatening bacterial infections such as meningitis, septicemia, and pneumonia in the neonates are more common than at any other time in life and signs of these infections are often subtle and non-specific. Because of these factors, the patient who has persistent fever will almost always be started on parenteral antibiotics immediately following evaluation. On the other hand there is also evidence that the hospital...
