  • Object : This study was undertaken to define the mechanism of GwakHyangJungGiSan-induced relaxation in rabbit common carotid artery contracted by agonists. Method : In order to investigate the effect of GwakHyangJungGiSan on rabbit's contracted vascular ring detached from common carotid artery, vascular ring intact or damaged endothelium was used for the experiment using organ bath. To analyze the mechanism of GwakHyangJungGiSan-induced relaxation, GwakHyangJungGiSan extract was infused into contracted vascular ring which had been pretreated by pretreatment of indomethacin(IM), tetraethylammonium chloride(TEA), $N{\omega}-nitro-L-arginine(L-NNA)$. Result : GwakHyangJungGiSan blocks an inflow of $Ca^{2+}$ and relaxes vascular ring by the action of Nitric oxide from endothelium. Consequently when GwakHyangJungGiSan is prescribed, a rise in blood pressure by the resistance of peripheral vessel may be controlled to some extent and so it is anticipated that hypertension, a disorder of blood flow from the vascular contraction and vascular disease will be treated well.

  • Pure esophageal atresia without tracheoesophageal fistula is a uncommon form of congenital malformation of the esophagus, which is able to be suspected by fetal ultrasonograpy before delivery and diagnosed definitely by simple chest X-ray and esophagogram immidiately after delivery. We performed delayed primary repair in 2 cases of pure esophageal atresia by using stomach for conduit in one case and colon in the other case. But there were graft failure in the latter case, so reoperation was performed by using stomach. Postoperatively, two patients showed no stenosis and leakage in anastomotic site and were discharged in good oral intake without dysphagia.

  • The trend of current urban redevelopment and new city development project shows that the superstructure of building is getting larger and higher in consequence of a limited plottage condition. For this reason, it is definitely required to extend pile diameter and install more deep foundation(Mega foundation) to support superstructure. The existing precast pile construction method causes construction-related problems such as increasing quantities, difficulty of storage & transportation material and decreasing design load while construct pile in deep foundation. The drilled shaft method has applied to minimize those problems. This article will be presented construction case study of design & construction of R.C.D method for a large building foundation work on the inside and outside of the country.
