A clinical study was done on 16 cases of cerebellar hemorrhage and 3 cases of cerebellar infarction which were diagnosed with brain CT scan at Keimyung university Dongsan hospital from July 1981 to June 1985 and conclusions obtained are as follows. 1. The incidence of cerebellar hemorrhage and infarction was 3.5% and 0.6% of all spontaneous intracranial parenchymal hemorrhage and infarction, respectively. 2. The most prevalent age group was 7th decade and sex ratio was higher in male in cerebellar stroke. 3. Major single percipitating factor of cerebellar stroke was hypertension. 4. Most of cerebellar stroke showed catastrophic or sudden onset type. 5. The most common initial symptoms of cerebellar stroke were nausea and vomiting, followed by headache and dizziness or vertigo, in order of frequency. 6. The most common neurologic signs on admission were impaired consciousness, constricted pupil with preserved light reflex and cerebellar signs. 7. The common site of cerebellar hemorrhage was right hemisphere, followed by vermis and left hemisphere, in order of frequency, and that of cerebellar infarction was right posterior hemisphere. 8. The better the consciousness on admission, the better the outcome of cerebellar stroke. 9. The following parameters indicated good prognosis with medical therapy, so called benign cerebellar hemorrhage: clear consciousness on admission, gradual onset type, less than 20cc of hematoma, no or mild hydrocephalus, no ventricular hematoma, no vermis involvement on CT scan.

After the performance of 100 coronary cineangiographies in 100 paitents who were adminitted to Soonchunhyang University Hospital under the diagnosis of ischemic heart disease from July 1986 to October 1987, we observed the coronary collateral circulation and measured the ejection fraction, circumferential fiber shortening, left ventricular end-diastolic pressure and pulmonary artery wedge pressure in 52 paitents who had 50% or more stenosis in one or more coroanry arteries. The results were as follow : 1) The collaterall circulation was observed in 16 patients(30.8%) of the 52 patients and it was developed mainly(87.5) in patients with 90% or more coronary artery stenosis. In patients with stenosis of less than 90%, however, collateral circulation was observed rarely(12.5%). 2) The left ventricular wall motion abnormality was severe in the group without collateral circulation. 3) The collteral circulation was most frequently developed in patients with severe right coronary artery stenosis and most of the routes were supplied from contralateral coronary arteries. 4) There was no significant difference in ejection fraction, circumferential fiber shortening, left ventricular end-diastoic pressure and pulmonary artery wedge pressure between the 2 groups with and without coronary artery collateral circulation.

Although it has been suggested that the calcium antagonist verapamil has beneficial effects on ischemic myocardium, its effect during coronary reperfusion has not been studied in detail. The purpose of this study was to investigate the inhibitory effect of verapamil on myocardial damage quantitatively using 111 In-anticardiac myosin antibody (ACM Ab) and qualitatively using electronmicroscopic method. Anesthetized open-chest dogs were subjected to 1 hour of occlusion of the left anterior descending coronary artery (LAD) followed by 90 minutes of reperfusion. Regional myocardial blood flow was determined by injecting 85Sr-microsphere prior to LAD reperfusion, and regional myocardial damage was measured by injecting 111In-ACm Ab at 30 minutes after LAD reperfusion. Six dogs were randomly selected as saline control and verapamil-treated (0.6 mg/kg. hr) groups each. Saline or verapamil was infused at 40 minutes after LAD occlusion and continued through the experiment. 1) Verapamil produced significant (P<0.05 by Wilcoxon rank sum test) decrease in heart rate, mean arterial blood pressure and double product. There was no significant change in pulmonary hemodynamics or cardiac output. 2) Stroke volume was reduced significantly (P<0.05 by Wilcoxon rank sum test) after 30 minutes of LAD reperfusion in the control group, but it was preserved in the verapamil-treated group. 3) There was an inverse exponential relationship between 111In-ACm Ab localization and regional blood flow in both control (r=-0.86) and verapamil treated (r=-0.71) groups. Significant difference between the two groups was found in exponential curve (p[t]<0.05). 4) A lesser uptake of 111in-ACM Ab was observed in the verapamil treated group compared with that in the control group in the region where the regional blood flow was lower than 30+/- of normal. 5) In the control group, the myocardium showed swelling, contraction bands, and electron dense granules in the mitochondria which were proven to be calcium aggregates. In the verapamiltreated grooup, the myocardium showed fewer electro dense granules and mild degree of contraction bands. This study supports the concept that verapamil reduces the myocardial damage following coronary reperfusion in myocardial infarction and may reduce contraction band necrosis.

To difine the relation between plasma atrial natriuertic peptide (ANP) levels and hemodynamic changes, we measured plasma concentration of atrial natriuertic peptide in 19 patients with heart disease undergoing cardiac catherization and in 15 normal subjects. The following results were obtained; 1) There were significantly increased plasma levels of atrial natriuertic peptide in patients with elevated mean pulmonary arterial wedge pressure. 2) A significant step-up in atrial natriuertic peptide concentration was seen between the femoral venous and right atrial plasma (P<0.01) and between the right atrial and pulmonary arterial plasma (P<0.05). 3) Peripheral venous atrial natriuretic peptide levels were significantly correlated with mean pulmonary arterial pressure and pulmonary wedge pressure (r=0.05, r=0.65, P<0.05). 4) Plasma atrial natriuretic peptide levels in pulmonary artery were significantly correlated with mean pulmonary arterial pressure (P<0.05).

Clincal studies were made on 166 cases of spontaneous subarachnoid hemorrhage (SAH), were admitted to the keimyung university Dongsan hospital from January 1981 to March 1984. The age and sex distribution, causes of SAH, clinical symptoms and signs, computed tomographic (CT) findings, aneurysmal site, number and size, comparison between the highest density on CT findings and site of aneurysm confirmed by angiography,relationship between CT class and clinical grade, complication, and relationship between hospital course and clinical grade on admission were analysed. The results summarized as follow. 1. The most prevalent age group was between 41-60 years of age, and above 61 years, 31-40 years and below 30 years of age in the order of frequency. Male to female ratio was 43.4 : 56.6. 2. The most common causes of 100 cases of SAH confirmed by cerebral angiography was cerebral aneurysm (75 cases), and the other causes were unknown cause (16 cases), arteriovenous malformation (6 cases), moyamoya disease (3 cases) in the order of frequency. 3. The clinical symptoms on admission in the order of frequency were headache, nausea and vomiting, brief loss of consciousness, dizziness, seizure, and urinary incontinence. The neurological findings showed stiffneck, hemiparesis, cranial nerve palsies, papilledema and/or hemorrhage on the fundus, and Babinski sign in that order. 4. CT findings (158 cases) revealed typical high densities consistent with SAH in 125 cases (79.1%), associated with the low density (13 cases), and visible cerebral aneurysm (5 cases), while negative findings were 33 cases (20.9%). 5. The most common site of aneurysm among the 75 cases of SAH confirmed by the cerebral angiography was the region of the anterior communicating artery (AcomeA) which accounted for 30 cases (35.3%), and posterior communicating artery (PcomeA) and middle cerebral artery (MCA) 23 cases (27%), respectively, the internal carotid artery 5 cases (5.9%), the anterior ecrebral artery (ACA) 2 cases (2.4%), the posterior inferior cerebellar artery and basilar artery 1 cases (1.2%), respectively in the order of frequency. Among the 75 cases of cerebral aneurysms, single aneurysms were 67 cases (89.3%) and multiple aneurysms were 8 cases (10.7%). The most common size of the aneurysms was 6-10 mm (47 cases), and below 5 mm (30 cases), and above 10 mm (8 cases) in the order of frequency. 6. Sixteen out of 27 cases of AcomA aneurysms present the highest density on CT scan in the anterior hemispheric fissure, 9 out of 22 cases of PcomA aneurysms in syulvian fissure and 6 cases in suprasellar cistern, and all cases of MCA aneurysm (21 cases) in the ipsilateral aneurysmal site. 7. Comparison between CT grade by Davis (1980) and clinical grade by Hunt-Hesse (1968) revealed that the 93 of 94 patients (pts) with CT class 1 or 2 belong to under clinical grade 3, the 17 of 64 pts with CT class 3 or 4 belong to clinical grade IV or V, and the 17 of 18 pts with clinical grade IV or V belong to CT class 3 or 4. 8. The most common complication was the hydrocephalus (30.1%), and cerebral arterial spasm (24.1%), SIADH (8.4%), and rebleeding confirmed by lumbar puncture and/or CT (4.2%), in the order of frequency. 9. One hundred and four pts (62.7%) out of total 166 patient with SAH were improved, whereas 39 pts (23.5%) were not improved or signed out without clinical improvement, and 23 pts (13.8%) were died. The 81 (77.9%) of 104 pts who were improved belong to clinical grade I or II on admission, the 18 (78.3%) of 23 pts who were expired belong to clinical grade III or IV, and the 19 (48.7%) of 39 pts who were signed out without improvement belong to clinical grade III to V.

Cardiovascular diseases have been the most serious threat to life and health. The socioeconomic ramifications of heart disease have long been a source of vexing legal as well as medical problems with no easy resolution as yet in hand. Heart weight, one of the important factors for the diagnosis of cardiomegaly and various heart diseases, shows extreme variability according to the height, weight, age, sex, nutritional status of individuals as well as other various factors. The purpose of this investigation was to find a practical method for calculating expected normal range of heart weight in a given individual. The study was performed on 259 autopsy cases of normal Korean men and women, consisting of 123 men and 136 women in age from newborn to 77 years old. Height, body weight, and heart weight were measured and the body surface area was calculated by height (cm)0.725 x weight (kg)0.425 x 71.84 and height (cm)0.7763 x weight (kg)0.4081 x 71.84 in men and women, respectively. The results showed that the mean heart weight of men and women older than 20 years old were 316.20 +/- 51.15 g (n=96) and 275.87 +/- 44.69 g (n=108), respectively. Heart weight was gradually increased according to the age. The body weight (men: r=0.81, women: r=0.84) and body surface area (men: r=0.83, women: r=0.83) were better univariate predictors of normal heart weight than body height (men: r=0.78, women: r=0.75) and age (men: r=0.42, women: r=0.57). No significant difference was found in predictive precision between body weight and body surface area. Since the body surface area was calculated from body weight and height, measuring the body weight was essential for calculating expected normal range of heart weight in a given individual, and calculation of expected normal range of heart weight using body weight was simpler method than using body surface area.

BACKGROUND: QT dispersion(QTD=QTmax-QTmin) on the 12 lead ECG has been known to reflect regional variation of ventricular repolarization, and thus a marker of an increased risk of arrhythmia events. Late potential(LP) on signal averagina ECG(SAECG) is independent risk factor of ventricular arrhythmia following acute myocardial infaction(AMI). However, the relation between LP and QTD as indicator of electrophysiologic instability in AMI remains to be determined. METHOD: To determine whether there is a difference in QTD between in parients with AMI during acute phase and in normal control and whether thrombolytic therapy is assiciated with a reduction in QTD, and to determine the relationship between change of QTD and late potential on SAECG, we studied 71 patient with AMI(male 54, female 14, mean age 57yrs) and 23 controls(malw 17, female 6, mean age 58yrs). QT interval was measured on a standard 12 lead ECG in patients with AMI on admission, 2 hours after urokinase IV and 10-14 days post-AMI, and QT dispersion was calculated by difference of maximal and minimal corrected QT interval(QTmax-QTmin). A signal averaged ECG was recorded in 36 patients before discharge and coronary angiogeaphy(CAG) was performed in all patients 10-14 days post-AMI. RESULT: QTD is significantly increased in AMI compared to control(78.7+/-39.5ms vs. 24.6+/-22.3ms, P < 0.01). In patients who received thrombolytic therapy with urokinase, QTD is decreased from 75.0+/-34.4ms to 53.9+/-36.0ms(P < 0.01), whereas there is no significant change in patients who did not received thrombolytic therapy(84.8+/-47.6ms vs. 78.9+/-36.2ms, NS). There in no difference in QTD between patients with positive LP(68.4+/-23.6ms) and those with negative LP(77.8+/-32.1ms) on admission, those with positive LP(66.6+/-27.6ms) and those with negative LP(56.0+/-26.4ms) after 10-14days post-AMI. But magnitude of change of 10-14 days post-AMI QTD in patients with negative LP is larger than those with positive LP(-21.7+/-33.4ms vs. -1.8+/-15.2ms, P=0.06). CONCLUSION: QTD in acute phase of AMI is significantly reduced by the thrombolytic therapy. Patients with negative late potential tent to have greater QTD reduction within 14 days after AMI. These finding suggest that QT dispersion in patients with AMI can be reduced by early recanalization and its reduction is associated with the presence of late potential.

PURPOSE: Idoxifene is currently entering phase II clinical trials for the treatment of advanced breast cancer. The radiolabeled idoxifene using 123I provides an opportunity for clinical pharmacology with single photon emission computed tomography (SPECT). The purpose of this study was to prepare radiolabeled idoxifene using 123I and to determine its cell uptake of breast cancer cell line. MATERIALS AND METHODS: With a view to evaluating new anticancer drugs, we are investigating the novel antiestrogen pyrrolidino- 4-iodotamoxifen (idoxifene). [123I]Idoxifene has been prepared in no-carrier-added form using a tributyl stannylated precursor which has been synthesized by means of (2-chloroethoxy)benzene with (+/-)-2- phenylbutanoic acid on the basis of previously reported standard methods. The biodistribution and dynamic behavior of the compound were investigated using the comparative breast cancer cell line, MCF-7 (estrogen receptor-positive) and MDA-MB-468 (non-estrogen receptor). RESULTS AND CONCLUSION: Acylation of (2-chloroethoxy)benzene with (+/-)-2-phenylbutanoic acid gave the versatile ketone (81%) which reacted with 1,4-diiodobenzene to give triphenylethylene as a mixture of E and Z geometric isomers, which were separated by the recrystallization in ethanol. The E-isomer was treated with pyrrolidine to give idoxifene (67%). In order to incorporate radioactive iodine into the 4-position, the 4-stannylated precursor was prepared (30%). The yield of radioiodination was 90-92% with a high radiochemical purity greater than 98%. The ratio of tumor uptake of the breast cancer cell line between MCF-7 and MDA-MB-468 was about 1.7.
