Retinal vein occlusion(RVO)is the second most common form of retinal vascular disease next to diabetic retinopathy. Systemic risk factors such as hypertension, diabetes, cardiovascular disease, blood dyscrasia and ocular risk factors such as short axial length, glaucoma, papilledema, thyroid ophthalmopathy have been shown to be associated with RVO. It is usually unilateral disease, and bilateral occurrene of RVO is relatively uncommon. CRVO rarely occurs bilaterally with a short interval between two eyes. Having experienced a case of bilateral CRVO within one month in a 75-year-old female with short axial length, primary open angle glaucoma, hypertension and hypercholesterolemia, we report this case with literature review.

PURPOSE: To report a case of Wegener's granulomatosis misdiagnosed as ocular tuberculosis. METHODS: A 65-year-old man who was treated with anti-tuberculosis medications as suspected pulmonary tuberculosis was referred from the department of internal medicine for visual loss over months. His initial visual acuity was counting fingers at 30 cm in the right eye and there was a chorioretinal scar involving the macula on fundus examination. At that time, we thought that the lesion was a tuberculosis-related chorioretinal scar and so he was treated with anti-tuberculosis medications. There was a recurrent bilateral anterior uveitis during three months from the initial visit. RESULTS: After 14 months, he was examined by otorhinolaryngologist due to a saddle nose deformity and Wegener's granulomatosis was diagnosed based on positive Cytoplasmic antineutrophil cytoplasmic antibody (c-ANCA) and nasal mucosal biopsy. At that time, ocular examination revealed the necrotizing scleritis in both eyes and orbital CT showed bony destruction of medial and inferior orbital wall without proptosis in both eyes. We had treated with oral cyclophosphamide and prednisone. CONCLUSIONS: We experienced a case of Wegener's granulomatosis with chorioretinal scar misdiagnosed as ocular tuberculosis. In conclusion, we should differentially diagnose Wegener's granulomatosis from suspected ocular tuberculosis.

PURPOSE: To report a case of Klebsiella pneumoniae endogenous endophthalmitis secondary to renal or urinary tract infection such as emphysematous pyelonephritis. METHODS: A-56-year-old woman with diabetes mellitus and emphysematous pyelonephritis was reterred to us in consultation for visual loss in her right eye for 5 days. Ophthalmologic evaluation and intervention were performed. RESULTS: Culture revealed Klebsiella pneumoniae from vitreous tap of the right eye. Systemic antibiotics, intravitreous antibiotics injection and vitrectomy were performed, but the eye showed progressive worsening to phthisis. CONCLUSIONS: A high index of suspicion of Klebsiella pneumoniae endogenous endophthalmitis must be carried in patients with renal or urinary tract infection such as emphysematous pyelonephritis as well as hepatobiliary disease such as pyogenic liver abscess.

BACKGROUND: The two most commonly used drugs as a stressor during wtress echocardiography are dipyridamole and dobutamine. The purpose of this study was to compare diagnostic accuracies of dipyridamole and dobutamine stress echocardiography for fixed coronary artery disease and evaluate complications related to the two agents in the same patients. METHODS: 30(M : 5=19 : 11, age=56+/-8.8yr) consecutive patients without history of previous myocardial infarction underwent coronary angiography, dipyridamole and dobutamine stress echocardiography in random order. Dipyridamole was infused up to 0.84mg/Kg for 10 minutes during clinical, ECG and echocardiographic montioring. Dobutamine was infused in dose increments from 5 to 40microg/Kg/min under the same condition. Positive criteria for myocardial ischemia by echocardiography was now regional wall mation abnormatity or worsening of regional wall motion after stress. Significant coronary disease was defined as more than 70% stenosis by coronary angiography. RESULTS: The sensitivity and specificity of both stress echocardiography were same, 82% and 92% respectively. In a single vessel disease the sensitivity of dipyridamole echocardiography was 75% and dobutamine echocardiography was 83% without statistical difference. The correlation of ischemic free time during both stress test was 0.375. During dipyridamole infusion no test was prematurely terminated because of side effects, but 3 patients(10%) developed severe hypertension and ventricular arrytricular arrythmia during dobutamine infusion and test was terminated. CONCLUSION: Thus, by this prospective direct comparison of both stress test, dipyridamole and dobutamine stress echocardiography have similar diagnostic accuracies for the detection of coronary artery disease. But during dobutamine infusion, careful monitoring for hemodynamic changes arrythmia is required for possible serious complications.

BACKGROUND: The presence of diastolic mitral regurgitation has been described in patients with complete atrioventricular(AV) block, aortic valve regurgitation, hypertrophic and restrictive cardiomyopathy, and in patients with long diastolic filling period in atrial fibrillation. However, because of rare incidence and difficulty in making diagnosis of this phenomenon, the frequency and hemodynamic effects of diastolic AV valve regurgitation(DAVVR) and relationship of electrocardiographic(ECG) parameters with DAVVR in patients with complete heart block have not been reported in Korea. METHODS: To evaluate the frequency, hemodynamic effects of DAVVR and relation of ECG parameters with DAVVR in patients with complete AV block, we studied 14 consecutive patients with complete AV block by means of two dimensional and Doppper echocardiography. RESULTS: The DAVVR was observed in all cases of complete AV block except 3 cases on temporary pacemaker. The peak velocy of diastolic mitral and tricuspid valve regurgitaton were 105+/-23cm/sec and 98+/-30cm/sec, respectively. The peak and mean pressure gradient of diastolic mitral regurgitation were 4.7+/-1.7mmHg and 3.1+/-1.5mmHg respectively, and the peak and mean pressure gradient of diastolic tricuspid regurgitation were 4.1+/-2.6mmHg and 2.7+/-2.1mmHg, respectively. There was regular interval between p-wave of ECG and onset of diastolic AV valve regurgitation, which was 215+/-12msec, Diastolic AV valve regurgitation disappeared immediately after recovery of complete AV block to sinus rhythm or insertion of DDD-type permanent pacemaker in all cases. CONCLUSION: In Conclusion, the DAVVR was observed in all cases of complete AV block except cases on temporary pacemaker insertion and its hemodynamic effect was mild. There was regular interval between p-wave of ECG and the onset of diastolic AV valve regurgitation.

BACKGROUND: Although there have been many studies on the risk factors for coronary artery disease, the etiology and risk factor of coronary artery spasm has not yet been determined. The objective of this study was to examine the risk factors for coronary vasospasm through a comparison of patients with angiographically determined vasospastic angina and patients without vasospasm and normal coronary artery. METHODS: Intracoronary injection of acetylcholine in order (20microg, 50microg, 100microg) were administered to all patients (Total 81:34 males, 47 females : mean age 50 years) who had a history of chest pain with normal or near normal coronary arteriographic fingings. After documentation of vasospasm in major epicardial coronary arteries by acetylcholine (Ach)-provocated dcoronary angiography, various risk factors (smoking, hypertension, diabetes, drinking and hyperlipidemia) were compared between patients with vasospasm and patients without vaspasm. RESULTS: 24 patients showed significant luminal narrowing (> or =75%)(Vasospasm group) and 57 patients showed no significant change (Control). Vasospasm group were suffered from typical chest pain in 92% of patients but control complained typical chest pain in 51% of subjects. The sites of vasoconstriction induced by Ach were LAD (11 cases), LCX (4 cases), RCA (11 cases) and vasoconstriction occurred 2 vessels (LAD and LCx) at the same time in two cases. The amount of Ach to provocate vasoconstriction was 20~50microg (90%) and there were no difference between left and right coronary arteries. The ratio of smoker was more frequent in the vasospasm group than control (58.3% vs 30.4%, p=0.046). But total cholesterol, low density lipoprotein, high density lipoprotein, triglycerides, apolipoprotein A, apolipoprotein B, lipoprotein (a), diabetes and body mass index, drinking were not statistically significant between two groups. CONCLUSION: Smoking appears to be a major risk factor for vasospastic angina by endotheilal dysfunction without significant coronary artery narrowing. But other fisk for coronary artery disease may not contribute to coronary vasospasm.

BACKGROUND: Left ventricular dilatation after acute myocardial infarction is caused by infarct expansion and compensatory dilatation of noninfarct area. This study was done to investigate the contributory topographical change of left ventricle to left ventricular dilatation after acute myocardial infarction. METHODS: 24 first acute myocardial infarction was studied with 2-dimensional echocardiography serielly. First study was done at 7days and second study was done 9 months after an infarction attack. Left ventricular volume was measured by Simpson's method in end-diastolic frame and change of end diastolic left ventricular surface area was measured in apical 4 chamber view. Left ventricular surface area was devided by ischemic(noncontraction) and nonischemic(contracting) area by connecting central point of long axis of left ventricle and the junction of dyssynergic motion and normal motion point in outer rim of left ventricle in end diastolic frame of apical 4 chamber view. RESULTS: Mean left ventricular end-diastolic volume at entry was 114+/-23ml and increased to 121+/-27ml at 9 months after acute myocardial infarction in whole group(p=0.02). In a subgroup of anterior infarction, the left ventricular surface area was increaed in 9 cases with increared left ventricular volume(34.8+/-5.1cm2 to 36.4+/-4.1cm2, p=0.02) and ischemic surface area did not change in these group. In 7 patients without increase in left ventricular volume, the left ventricular surface area did not change and ischemic surface area decreased(9.4+/-4cm2 to 8+/-3.2cm2, p=0.03) at 9 months. CONCLUSION: Thus the increase in left ventricular end-diastolic volume between 13 days and 9 months after acute myocardial infarction is considered to be a consequence of noninfarct ventricular area dilatation.

BACKGROUND: Celiprolol is a new generation beta-adrenoreceptor blocking agent with intrinsic sympathomimetic activity characterized by selective blockade of beta1 receptors and partial agonist activity at beta2 receptors. This study was designed to investigate the antihypertensive efficacy and safety of celiprolol in patients with essential hypertension. METHODS: The study subjects consisted of 36 patients(mean age : 55 years, 11 males, 25 females). Celiprolol was administered orally in a aily dose of 200-800mg once or two divided dose for 10 weeks after the admimstration of placebo for 2 weeks. RESULTS: Blood pressure was significantly reduced from 171+/-19/106.8mmHg to 153+/-20/92+/-12mmHg(p<0.01) after 2 week of therapy and this effect was maintained throughout the study periods. The efficacy rates were total 94%(marked improve : 53%, moderate improve : 22%, mild improve : 19%). The cumulative efficacy rate was 72% at 200mg/day, 91% at 400mg/day, and 94% at 800mg/day. Heart rate did not change throughout 10 weeks. There were no significant change in hematologic and blood chemistry variables. During the period of medication, headache developed in 3 cases(8%) and each of dry cough, dyspnea, epigastric pain and diarrhea and facial flushing developed in 1 case(2.8%) but they were tolerable. CONCLUSIONS: This results suggest that celiprolol is effective and safe drug in the treament of patients with essential hypertension.

AIMTo investigate the antioxidant effects of Morinda officinalis (Morindae radix, MR) on H(2)O(2)-induced oxidative stress in cultured mouse TM3 Leydig cells.

METHODSWe carried out 2,2-diphenyl-1-picrylhydrazyl free radical scavenging, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide, lipid peroxidation, testosterone enzyme immunoassay, superoxide dismutase (SOD), and catalase (CAT) assays in Leydig TM3 cells.

RESULTSMR showed a 47.8% 2,2-diphenyl-1-picrylhydrazyl radical scavenging effect in TM3 cells with no significant cytotoxicity. Oxidative stress was induced in TM3 cells with 100 micromol H(2)O(2), and treatment of the cells with 250 microg/mL MR showed the most significant protective effect (64%, P < 0.001) in the cell viability assay with a decreased lipid peroxidation level (1.75 nmol/mg protein, P < 0.05), increased testosterone production (43.5 pg/mL), and improvements in SOD activity (7.49 units of SOD/mg protein, P < 0.001) and CAT activity (74.6 units of CAT/mg protein, P < 0.001).

CONCLUSIONThese findings indicate that MR, as an antioxidant, protects functions of cultured mouse TM3 Leydig cells from H(2)O(2)-induced oxidative stress.
