Clonorchiasis procucts diffuse dilatation of the small and medium sized intrahepatic bile ducts and its cholangiogram shows visualization of many bile ducts, especially, tertiary, quaternary, and more peripheral tributaries up to the 6th tributaries. In an attempt to clarify this cholangiographic sign quantitively, we counted the visualized smaller bile ducts in clonorchiasis and compared the number of visualized ducts in normal cholangiogram, recurrent pyogenic chlangitis and carcinoma of the extrahepatic ducts. In clonorchiasis the number of visualized smaller bile ducts was considerably geater than in normal subjects and recurrent pyogenic cholangitis, but there was no singnificant statistical differences in the number of visualized bile duct tributaries between clonorchiasis and carcinoma of the bile ducts. Thus it is considered that too many ducts sign is not a unique cholangiographic finding of clonorchiasis, but we believe that in the presence of this sign with other we l known cholangiographic findings, diagnosis of clonorchiasis is very easy.

CT has become the most useful, non-invasive diagnostic method as the initial exmination in the diagnosis ofruptured intracranial aneurysm with intracranial hemorrhage(subarachnoid, intracerebral and intraventricularhemorrhage), hydrocephalus and infarction. Furthermore, high resolution CT can demonstrate aneurysm itself. Butangiography is the last and conclusive method as yet, for better evaluation of vascular anatomic structure ofaneurysm for surgery. Authors analyzed 40 cases of ruptured intracranial aneurysm confirmed by CT, angiographyand/or surgery at Chonnam National University Hospital from July, 83' to July, 85'. The results were as follows:1. The most prevalent age group was the 5th decade(35%), and female patient(57.5%) was more comon than male. 2.Angiographic findings were as follows: 1) Multiple aneurysm was found in 8 patients (20%): the one of thesepatients is tripple, the others are double. 2) The location of aneurysm, in order ot frequency, were : ACA andA-com aneurysm in 23 cases(47%). ICA and P-com aneurysm in 17 cases(35%), basilar tip aneurysm in 4 cases(8%), MCAaneurysm in 3 cases(6%) and PCA aneurysm in 1 case(2%). 3) Hydrocephalus was detected in 22 cases (55%): 21 cases(95%) of these cases were demonstarated within the first 3 weeks after attack. 4) Detection of aneurysm itseslfwas 20 cases(50%). 5) Cerebral infarction was 5 cases(12.5%). 6) Subarachnoid enhancement on post-contrast scanwas 8 cases(20%).

To assess the likelihood of procedural success in patients with multivessel coronary artery disease, 46 consecutive patients (male 34, female 12, mean age 60+/-9 years) umderwent single or multiple site angioplasty. The clinical diagnosis of unstable angina was in 20(44%), stable angina in 10 and acute or old myocardial infarction in 16. Coronary angiographic findings of 2 vessel disease was in 38(83%), triple vessel disease in 8. Left ventricular function was generally well preserved (mean ejection fraction 65+/-12%, range 30-82%) and mean 2.0 stenosis per patient angic, lasty had attempted. Single vessel angioplasty (SVA) was performed in 13 and multivessel angioplasty (MVA) in 33. Procedural success was achieved in 79(86%) out of total 92 stenoses. Sixty-six(88%) out of 75 stenoses in MVA and 13(76%) out of 17 stenoses in SVA had procedural success respectively. According to angiographic morphology of lesions, procedural success of type A stenoses was 17/17(100%), type B stenoses 57/66(86%) and type C stenoses was 5/9(33%). In 13 failures included inability to pass the guide wire cross the lesion in 7, inability to guide the griding catheter in 2 and inability to dilate lesions in 4. Before and after angioplasty, treadmill test (modified Bruce protocol)could be performed in 29 patients. Total duration of exercise and maximal double product improved significantly from 8.5+/-2.3 minute 5188+/-2403 to 12.2+1.3 min., 23,062+/-4111 respectively (p<0.001). 17 out of 24 patients who had positive treadmill test before angioplasty showed negative conversion after procedure. Complications included dissection in 29, prolongd chest pain in 5, acute closure in 3, cardiac tamponade in 1 and ventricular fibrillation due to side branch oclusion in 1. Thus, coronary angioplasty in selected paients with multivessel coronary artery disease might be useful and have relatively good immediate results, but the long-term efficacies with other forms of treatment must be evaluated prospectively.

Clonorchiasis is known to be closely related with the development of recurrent pyogenic cholangitis and carcinoma of the bile ducts. In order to ascertain the cholangiographic signs for recurrent pyogenic cholangitis or carcinoma of the bile ducts arising in patients with clonorchiasis. we reviewed cholangiograms in 42 patients with proven clonorchiasis. The population consisted of 29 patients with clonorchiasis alone, six patients with clonorchiasis and recurrent pyogenic cholangitis, and seven patients with clonorchiasis and carcinoma of the bile ducts. Cholangiographic abnormalities in 29 patients with clonorchiasis alone, six patients with clonorchiasis and recurrent pyogenic cholangitis, and seven patients with clonorchiasis and carcinoma of the bile ducts. Cholangiographic abnormalities in 29 patients with clonorchiasis alone were intrahepatic multiple, oval, or elliptic filling defects measuring 2-10 mm in size, representing adult flukes (n=24). The peripheral bile duct were obstructed (n=18), and the margins were ragged (n=20) and hazy (n=12) the intrahepatic bile ducts were dilated diffusely (n=27), and the dilated peripheral small tributaries gave the impression of "too many ducts appearance" (n=7) and dilatation was mid (n=17) In six patients with clonorchiasis and recurrent pyogenic cholangitis, there were filling defects of stones, and the extrahepatic ducts and larger intrahepatic ducts were predominantly dilated. In seven patients with clonorchiasis and cholangiocarcinoma all the biliary tree proximal to the tumor was markedly and diffusely dilated In the latter two groups, filling defects of flukes and associated findings were less prominent, but there was disproportionately severe dilatation of too many intrahepatic ducts. In patients with recurrent pyogenic cholangitis or cholangiocarcinoma, clonorchiasis should be considered as a underlying cause when cholangiogram shows "disproportionately" severe dilatation of too many intrahepatic ducts. intrahepatic ducts.

BACKGROUND AND OBJECTIVES: Cardiac troponin T (cTnT) has been used as a very sensitive marker of cardiac injury caused by ischaemia, myocarditis, and cardiomyopathy. After cardiac injury, the fetal cTnT isoform expression in the heart and serum cTnT increases. To investigate the increased levels of serum cTnT, and the expression of fetal cTnT isoform in the heart, that can predict myocardial injury, we measured serum cTnT levels and the fetal cTnT isoform expression at various time points during the early phase of myocardial toxicity induced by adriamycin (ADR) in rat. MATERIALS AND METHODS: Male Sprague-Dawley rats were injected, intraperitoneally, with ADR (5 mg/kg) twice a week for 2 weeks. Control rats were injected with saline. Serum cTnT levels were measured by ELISA. The ratio of fetal/adult (F/A) cTnT isoform expression (%) was semi-quantified by RT-PCR using total RNA from frozen hearts. RESULTS: Serum cTnT levels did not increase by 1 week after ADR injection, but increased significantly after 2 weeks. The ratio of F/A cTnT in the heart significantly increased from day 1, peaked at 1 week and persisted until the end of 2 week. CONCLUSION: The expression of the fetal cTnT isoform occurred from 1 day after ADR injection when the serum cTnT levels were still normal. Although the serum cTnT level is a very sensitive, and an early marker, of cardiac damages, the fetal cTnT isoform expression in the endomyocardial biopsy specimen may be a more sensitive and an earlier marker in the ADR-induced myocardial damage.

Carbamylated hemoglobin (CarHb) is formed by the reaction of hemoglobin with cyanate derived from the spontaneous dissociation of in vivo urea. Previous studies have shown that formation of CarHb depends upon both the severity and the duration of renal failure. To study the clinical significances of CarHb in Korean patients with chronic renal failure, we measured CarHb levels by high-performance liquid chromatography in 159 CRF patients and 46 normal controls. Patients with CRF had a higher CarHb concentration than normal controls (107.9+/-58.8 vs 35.1+/-14.2 microgramVH/gHb; P<0.001). In patients with CRF, nondialysis group had a higher value than dialysis group (129.8+/-77.9 vs 98.7+/-46.1 microgramVH/gHb; P<0.05). There were no siginificant difference in CarHb levels between hemodialysis (92.0+/-35.8microgramVH/gHb) and peritoneal dialysis (106.7+/-55.3microgramVH/gHb) groups. CarHb levels were not different between diabetic and nondiabetic patients in predialysis and hemodialysis groups. Although there was a significant difference in peritoneal dialysis group, the BUN levels were also lower in diabetic patients than nondiabetic patients. There were no correlation between CarHb and HbA1c percentage in patients with diabetes. CarHb levels were positively correlated with BUN (r=0.489; P<0.001) and creatinine (r=0.458; P<0.01) concentrations. There were negative correlations between CarHb and both Kt/V (r=-0.358; P<0.05) and URR (r=-0.415; P<0.05) in hemodialysis patients. In conclusion, CarHb may be a useful index of uremic control in patients with chronic renal failure, and are independent of the mode of dialysis and the presence of diabetes.

Acute focal bacterial nephritis(AFBN) is an unusual form of localized renal infection, which has various imaging findings and should be distinguished from abscess or other renal masses. Clinical symptoms are similar to other urinary tract infections but the diagnosis needs a CT or sonographic confirmation. Treatment, which is nonoperative, consists of intensive antibiotic therapy. We report three cases of AFBN with urinary tract infection in an 11-month-old, 9-month-old female and 8-month-old male patients, respectively. The confirmative diagnosis was done by localized intrarenal solid mass lesion by sonography. They were treated with intravenous and oral antibiotics for 6, 4 and 2weeks, respectively. Follow-up urinalysis, urine culture and sonographic finding were normal after treatment.

PURPOSE: To evaluate characteristic MR findings of primary cardiac and pericardiac tumors. MATERIALS AND METHODS: There were myxomas (n=7), malignant lymphoma (n=l), lipoma (n=l), and pericardiac mesotheliomas (n=2). We analyzed location, size, shape, signal intensity, contrast enhancement, and associated findings of adjacent structures such as pericardiac and pleural effusion, and mediastinal lymph node enlargement. RESULTS: Locations of the myxomas were left atrium in four cases, left ventricle in one, right atrium in one, and right ventricle in one. Mean diameter was 3.5cm (range, 2-7cm). They were polypoid or Iobulated in shape, and attached to interatrial or interventricular septurn in all cases except in right atrial myxoma which was attached to lateral wall. Their peduncles were demonstrated in three left atrial myxomas. The signal intensities were iso or slightly high on T1-weighted images and high on T2-weighted images. Pleural and pericardial effusions were shown in the three cases. Malignant lymphoma was manifested as large mass in right ventricle infiltrating to right atrium, interventricular septum, right paratracheal and retrocardiac area. It had slightly high intensity in both T1- and T2-weighted images with a strong contrast enhancement and associated with both pericardiac and pleural effusion. Lipoma was polypoid in shape and attached to lateral wall of left ventricle with bright T1 and high T2 signal intensity. Pericardiac mesothelioma was manifested as a pericardiac and atrial mass with diffuse irregular uneven thickening of pericardium which had iso signal on T1- and high T2-weighted images with moderate contrast enhancement. Conculsion: MR imaging is a very useful method in demonstration of the location, extent, tissue characteristics of the mass, and relationship with its adjacent structu res in evaluation of cardiac and pericardiac tumors.
