With 2mm-thick CT scanning during the rapid infusion of contrast material(TICT), cerebral aneurysms arising from the circle of Willis and adjacent vessels can be directly visualized. Twenty-five patients who had cerebral aneurysm confirmed by surgery were examined with TIGT and digital subtraction angiography. The authors examined TIGT prospectively to assess the detection rate of the cerebal aneurysms and to evaluate the clinical usefulness of TIGT. The detection rates of aneurysms by TIGT and digital subtraction angiography were 68% and 84%, respectively. TIGT is a rapid, safe and reliable method in the evaluation of patients with suspected cerebral aneurysm, permitting direct visualization of the aneurysm.

Arteriovenous mafformation(AVM) of female pelvic organ is a rare disease of unknown cause. The authors' report a case of pelvic AVM which was incidentally found during US examination of the patient with choriocarcinoma after chemotherapy. The real-time sonography revealed several cystic lesions around the uterus with adjacent dilated tortuous vessels. The color Doppler sonography depicted abundant blood flow mixed with red and blue colors within the cystic lesions and rapid turbulent systolic and diastolic flows. CT showed well-enhancing round vascular lesions with elongated vessels in the pelvis, and MRI depicted signal-void cystic lesions on both T1 and T2 weighted images with small portions of high intensity within the lesions on T2 weighted image. The angiography revealed pelvic AVM fed by tortuous uterine and vaginal arteries with a dilated draining vein

The author measured the value of serum triglyceride, total cholesterol and phospholipid in normal Korean adults and patients with complicated hypertension. Sera obtained from 295 cases of normal Korean male and female, and also 109 cases of patients with hypertension were analysed for triglyceride, cholesterol and phospholipid. The patterns of serum lipoprotein fraction in 171 normal Korean and 109 patients with complicated hypertension including cerebrovascular diseases and ischemic heart disease were studied by agarose gelelectrophoresis. The results are summarized as follows; 1. The mean value of serum triglyceride, cholesterol and phospholipid in normal Korean were 85.4+/-20.5mg%, 187.9+/-16.7mg%, and 193.4+/-34.6mg% respectively. 2. Sex and age difference showed no statistical significance in the mean values of serum triglyceride, cholesterol and phospholipid in hypertensive patients. 3. The mean values of serum triglyceride in the patients with complicated hypertension such as cerebral thrombosis gave higher value than in the patients with other cerebral complications. 4. The mean value of alpha-lipoprotein, pre-beta-lipoprotein and beta-lipoprotein in normal Korean were 29.6+/-5.0% (142.6+/-30.1mg%), 13.0+/-4.3% (62.7+/-24.8mg%), and 57.4+/-30.1% (276.1+/-56.6mg%) respectively. 5. The alpha-lipoprotein fraction in normal Korean demonstrated the tendency of decreasing as age is progressing in both sex, but pre-beta and beta-lipoprotein fraction gave a tendency of increasing by progressing age in both sex, but was not confirmatory in nature. 6. The alpha-lipoprotein fraction in patients with hypertension gave lower value than in the normal subjects, but the value of pre-beta and beta-poprotein were elevated significantly among patients with complicated hypertension than in normal person. 7. The incidence of hyperlipidemia in normal Korean and patients with hypertension were 31.9% and 66.5% respectively. 8. The relative incidences of hyperlipidemic probable phenotypes in normal Korean were as follows: 7% of normal person had Type II (IIa 3.3%, IIb 3.7%), 3.5% had Type III, and 21.4% had Type IV.

BACKGROUNDS: The pathophysiology of chronic airflow obstruction, such as bronchial asthma, is characterized by mucus hypersecretion, goblet cell hyperplasia(GCH), smooth muscle hypertrophy, cells infiltration. In fatal asthma patients, one findings is mucus hypersecretion due to GCH. However, the mechanisms of GCH in these hypersecretory diseases remain still unknown. In this study, a rat model was rapidly induced with GCH by instillation of TiO2 intratracheally. We intend to confirm GCH and association of concomitant inflammatory cells infiltration and to observe the effect of potent antiinflammatory agent, that is dexamethasone, on GCH with inflammatroy cells. METHODS: Twenty-one-8-weeks-old male Sprague-Dawley rats were divided into three groups. Endotoxin-free water was instilled intratracheally in group 1(control) ; TiO2 was instilled in the group 2 ; and dexamethasone was injected intraperitoneally to group 3 before TiO2 instillation. After 120 hours, all rats were sacrificed, and trachea, bronchi, and lungs were resected respectively. These tissues were made as paraffin blocks and stained as PAS for goblet cells and Luna stain for eosinophils. We calculated the ratio of goblet cell to respiratory epithelium and number of infiltrated eosinophils from each tissue. RESULTS: (1) Fraction of goblet cells was significantly increased in group 2 than in group 1 in the trachea and in the main bronchus. (10.19±11.33% vs 4.09±8.28%, p<0.01 and 34.09±23.91% vs 3.61±4.84%, p<0.01, respectively). (2) Eosinophils were significantly increased in the airway of group 2 than that of group 1. (5.43±3.84% vs 0.17±0.47 in trachea and 47.71±16.91 vs 2.71±1.96 in main bronchi). (3) There was significant difference in the decrease of goblet cells and eosinophils(r=0.719, p=0.001). (4) There was significant difference in the decrease of goblet cells after dexamethasone infection between group 2 and group 3 (p<0.01). Also, infiltration of eosinophils was suppressed by dexamethasone. CONCLUSION: We made an animal model of TiO2-induced goblet cell hyperplasia. GCH was observed mainly in the main bronchi with concomitant eosinophilic infiltration. Both goblet cell hyperplasia and eosinophilic infiltration were suppressed by dexamethasone. This animal model may serve as a useful tool in understanding of the mechanism of GCH in chronic airway diseases.

The nerve root block or selective nerve root block is one of the primarily preoperative diagnostic tool to identify and confirm the lesion site of primary cause of pain and that is considered as one component of a comprehensive treatment program. The purpose of our study is to evaluate the effect and duration of the pain control by selective spinal nerve root block as a conservative treatment in patients presenting with chronic or recurrent sciatica. The authors performed 95 selective nerve root blocks in 72 patients from Sep. 1994 to May. 1996, (mean follow up 11.6 month) at the department of orthopedic surgery, Kosin University Gospel Hospital, and the results were as follows: 1. Among 72 cases, spinal stenosis was in 45 cases (62.5%), HIVD in 19 cases (26.4%), failed back syndrome in 5 cases (6.9%), spondylosis in 2 cases (2.8%), and spondylolisthesis in I case (1.4%). 2. In 72 cases, improved more than 50% of sciatica were 61 cases (84.7%) at 3 hours, 53 cases (73.6%) at I week, 35 cases (48.6%) at 1 month, 33 cases (45.8%) at 3 months, and 33 cases (45.8%) at 6 months respectively. 3. At last follow-up, excellent and good results were 35 cases (48.6%), fair results were 25 cases (34.7%) and poor results were 12 cases (16.7%) by the Kirkaldy-Willis criteria. 4. Complications were 1 case of transient hypotension, 2 cases of severe paresthesia, but subsided without residual complication. Therefore, the selective nerve root block is one of the valuable procedure that is helpful and extremely safe in useful treatment for radicular pain associated with lumbar disease. And the trial of selective nerve root block was recommended before deciding surgical intervention on an outpatient basis.

PURPOSE: Congenital Iobar agenesis of the liver is a rare anomaly. We report five cases (three cases of right Iobar agenesis and two cases of left Iobar agenesis) and discuss the radiologic findings of this congenital anomaly. MATERIALS AND METHODS: Between July, 1992 and February, 1993, three cases of right Iobar agenesis and two cases of left Iobar agenesis of the liver were diagnosed by means of computed tomography(CT) and/or sonography. MR imging was performed in two patients, cholangiography in two, and digital subtraction angiography in one. RESULTS: The main findings of right Iobar agenesis of the liver were nonvisualization of the right portal vein and absence of liver tissue to the right of gallbladder. The findings of left Iobar agenesis were nonvisualization of left portal vein, absence of liver tissue to the left of the gallbladder, and absence of ligamentum teres. The ancillary finding of the Iobar agenesis was visualization of less than three hepatic veins. CONCLUSION: It is important to consider Iobar agenesis of the liver in differential diagnosis when imaging studies reveal abnormal portal vein branches, unusual position of gallblader, absence of ligamentum teres, and visualization of less than three hepatic veins.
