Background : Garlic is one of the important vegetables and a source of natural anti-oxidants. This study was carried out to investigate the antioxidant activities including 2,2-diphenyl-1-picr yl-hydrazil (DPPH), 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS), ferric reducing antioxidant power (FRAP), reducing power (RP) and total polyphenol content (TPC) of A. ampel oprasum L. Methods and Results : DPPH, ABTS, FRAP, TPC, and RP were analyzed the extract of aerial plant part in 22 accessions of A. ampeloprasum by spectrophotometry mathod. A. tuberosum Rottler ex Spreng. was used as a control. DPPH was ranged from 0.35 to 3.06 ㎍ ASC ㎎-1 dw. ABTS and FRAP showed wide variation from 4.37 to 29.30 ㎍ Trolox ㎎-1 dw and 3.18 to 10.8 ㎍ ASC ㎎-1 dw, respectively. RP and TPC were ranged from 3.43 to 9.51 ㎍ GAE ㎎-1 dw, and 0.8 to 18.63 ㎍ ASC ㎎-1 dw, respectively. Cluster analysis of A. ampeloprasum germplasm was divided into two major groups. Group Ⅰ (7 accessions) characterized as higher antioxidant activities than the group Ⅱ (15 accessions) and had similar antioxidant activities with A. tuberosum as a control. FRAP value showed a significant strong positive correlation with DPPH (r = 0.868*) and ABTS activity (r = 0.826*). Principal component analysis showed that the first two principal components (PC1 and PC2) cumulatively explained 85.64 % of total variation. Conclusion : From the above results, we may suggest that A. ampeloprasum aerial parts might have useful as a new material for functional food.

The patent ductus arteriosus (PDA) is a vascular structure connecting the proximal descending aorta to the roof of the main pulmonary artery, near the origin of the left branch pulmonary artery. Transcatheter closure has become the treatment of choice for most cases of PDA in both children and adults; however, measurement of the exact size and morphology of the shunt in adult cases using only contrast fluoroscopy is difficult. We report on a case of a 49-year-old woman who underwent transcatheter closure of PDA with intravascular ultrasound (IVUS) guideance. In the current case, IVUS is feasible and helpful for measuring the exact size and shape of the PDA.
