Jin Young Cho, Young Wook Yoon, Hyang Suk Yoon, Jong Duk Kim, Du Young Choi
Clin Exp Pediatr. 2006;49(4):439-445.   Published online April 15, 2006
Purpose : α-Galactosylceramide (α-GalCer)-stimulated human Vα24 natural killer T (NKT) cells exert antitumor activity against some leukemia in a CD1d dependent and TCR-mediated manner, but could not kill CD1d - negative neuroblastoma (NB) cells. There are few reports about the direct antitumor effect of highly secreted cytokines by these cells on activation. In this study, using a cell-free supernatant (SPN)...

A Case of Intussusception Caused by Meckel's Diverticulum in a Newborn
Seung Taek Yu, Yeon Kyun Oh, Won Churl Park, Eun A Kim, Chang Woo Lee, Hyang Suk Yoon
Clin Exp Pediatr. 2005;48(8):907-910.   Published online August 15, 2005
Intussusception and Meckel's diverticulum are very rare disorders in intrauterine or neonatal periods, which are causes of intestinal obstruction. We experienced a case of intussusception due to Meckel's diverticulum which caused intestinal obstruction in the neonate who had bilious vomiting a few hours after birth. We report this case with a brief review of the literature.

Echocardiographic Evaluation of the Natural Processes in Uncomplicated Ventricular Septal Defect
Hyang Suk Yoon, Du Young Choi
Accepted January 1, 1970  
We studied, with echocardiography as a main tool, the natural processes of 211 patients with uncomplicated ventricular septal defect(VSD)(incidence, 5.33 per 1,000 live births); 146(69.2%) had a perimembranous VSD and 32 (15.2%) had a subarterial, 25(11.8%) had a muscular type of VSD. Cumulative rate of spontaneous closure was 26.1%. In the closure processes, about three-fourth of perimembranous VSd showed a...

The Mitral Regurgitation in Patent Ductus Arteriosus (PDA)
Hyang Suk Yoon, Soon Ho Choi
Clin Exp Pediatr. 1994;37(3):317-321.   Published online March 15, 1994
Mitral regurgitation (MR) was analyzed by Doppler echocardiography, preoperatively and postoperatively, in 59 patients with patent ductus arteriosus (PDA). The ratio of left atrial dimension and aortic root dimension (LAD/LOD) and the maximal velocity of the mitral valve (MV max) were compared in pre, postop group. The degree of the regurgitation was given to the MR group. In preop MR...
The Risk of Seizure Recurrence of Pediatric Epileptic Patients While Receiving Anticonvulsant Drugs Treatment

Clin Exp Pediatr. 1993;36(9):1271-1278.   Published online September 15, 1993
To evaluate the risk and factors associated with seizure recurrence on children with epilepsy while receiving the adequate anticonvulsant treament, we studied 58 patients with newly diagnosed epilepsy who were followed prospectively for a median of 26 months (range 7 to 54). The results were as follows: 1) Forty-four of the 58 patients (75.9%)had recurrence...
