We describe a case of xanthoma on the corneoscleral limbus in a 21-year-old man. It was characterized by a localized, round, elevated, yellowish mass on the right superonasal limbus with 6mm in size. There was no correlation with systemic or metabolic diseases such as hyperlipidemia and the microscopic examination revealed scanty fibrous element.

Thirty three patients with mild to moderate essential hypertension were administered ramipril, a new ACe inhibitor, 2.5-5mg once daily for 6 weeks to evaluate the hypotensive efficacy and safety. The results were as follows : 1) The patients consisted of 18 males, 15 females, aged 54 on average and classified as mild in 19 and moderate in 14 patients. 2) At the end of 6 weeks trial, blood pressure dropped 13/6mmHg on average, rewarding 70% effectiveness and normalized below 150/90mmHg in 39%. 3) The most frequent side reaction was dry cough in 5 patients(15%) followed by asthenia, GI trouble, dizziness, edema, eye injection and one case of GPT elevation which normalized after completion of trial. 4) The rating of safety of safety was 79% and of overall usefulness was 73%. In conclusion, ramipril 5mg once daily regimen is well tolerated and effective in the treatment of mild to moderated essential hypertension.

Endothelin(ET) is known as a family of potent hydrophobic, vasoactive peptide. We investigated the effect according to the concentrations of ET on intraocular pressure(IOP), aqueous outflow facility, pupillary diameter and light reflex and iris vessels. Twenty-four hours after injection of 2.5 microgram and 10 microgram of ET-1 into the anteriorvitreous of rabbit eyes, the IOP was reduced by 69% and 80%, respectively and did not return to the level of prefreatment until at least 14 days and 20 days, respectively. But the decrease of IOP was not due to the increased aqueous outflow. The pupillary diameter of ET-1 treated eyes was 1 to 2mm larger than the pretreatment. The time course of the pupillary effects generally ran paralled with the reduction of IOP. The iridial and conjunctival hyperemia was detectable during the pupillary dilatation. Endothelins are therefore potential participants in the local regulation of IOP, ocular blood vessel tone, and iris smooth muscle tone.

PURPOSE: Levofloxacin has been widely used because of its broad spectrum and excellent penetration of the prostate. But levofloxacin-resistant Escherichia coli (E.coli) has been reported all over the world. We analyzed the annual levofloxacin resistance of E. coli and its risk factors. MATERIALS AND METHODS: From 2005 to 2009, we retrospectively analyzed patients who had undergone a urine analysis and a urine culture at the Outpatient Section of the Department of Urology of Kwangju Christian Hospital. Among them, we chose 509 patients infected by E. coli and evaluated the resistance rate to levofloxacin and its risk factors. RESULTS: The annual rates of levofloxacin resistance of E. coli were 29.49% in 2005, 26.51% in 2006, 40.21% in 2007, 43.20% in 2008, and 31.75% in 2009. A close correlation with the resistance rate was shown in cases that had underlying neurogenic bladder (p=0.002, odds ratio [OR]=4.236), a history of ciprofloxacin (p<0.001, OR=3.753) and levofloxacin (p<0.001, OR=2.996) administration for at least 48 hours in the past year, urolithiasis (p=0.003, OR=3.317), and older age (p<0.001, OR=1.027). CONCLUSIONS: This study from 2005 to 2009 showed that the levofloxacin resistance rates of E. coli were high at over 25%. The risk factors that affected the levofloxacin resistance rates of E. coli were underlying neurogenic bladder, ciprofloxacin administration history, urolithiasis, levofloxacin administration history, and older age. Levofloxacin should be prescribed cautiously in patients with these risk factors until the pathogen is identified.

The objective of the present study is to obtain information on the hemodynamic characteristics in the anastomotic sites of femoral artery through the vascular implantation. Three dimensional steady and physiological blood flows in the femoral artery are simulated using the finite volume method. The geometrical shape of the anastomotic sites is made based on the vascular anatomy of a white rabbit. Wall shear stress distributions in the anastomotic sites for the physiological flow are compared with those for steady flow. Blood flow phenomena in the anastomotic sites of the femoral artery are discussed extensively.

The hemodynamic characteristics of the cuff end-to-side anastomosis model are investigated using by the finite volume predictions. The flow rates and the impedance indices through of the cuff anastomosis model are compared with those of the anastomosis model without the cuff. Blood flow increased through the cuff anastomosis model than the standard anastomosis model. The impedance index decreased with the increase of flow rate. The impedance index at a given flow rate is reduced by the increase of anastomosis angle and further reduced by the addition of the cuff. The results suggest that the cuff anastomosis model should be applied for the low Reynolds number flow and/or the small artery anastomosis model.
