PURPOSE: Endothelin-1(ET-1) is a potent vasoconstrictor peptide. It has potent contractile and proliferative effects on vascular smooth muscle cells. Congenital heart diseases are often accompanied by pulmonary hypertension, and the severity of pulmonary hypertension is important in the prognosis. The aim of this study was to elucidate changes of ET-1 after pulmonary venous stenosis in a dog model, and investigate the interaction between pulmonary venous pressure and ET-1. METHODS: Plasma ET-1 levels were measured by radioimmuno-assay at the thoracic aorta, left pulmonary artery and left pulmonary vein. Pressures were also monitored at the same sites. Immunohistochemical staining of ET-1 was performed in the lung tissue. RESULTS: Increased serum ET-1 levels were noted at 1 hour after left pulmonary vein stenosis in the left pulmonary vein and aorta, and at 2 days after stenosis in the left pulmonary artery. Left pulmonary venous pressure was significantly increased at 1 hour after pulmonary vein stenosis, and systolic pulmonary artery pressure at 2 days after stenosis. Increased expression of ET-1 was noted by immunohistochemical staining at the lung tissue at 7 days after stenosis of left pulmonary vein. CONCLUSION: Increased serum ET-1 level and expression of ET-1 in immunohistochemical staining at lung tissue were noted after stenosis of pulmonary vein. Serum ET-1 level would be useful in the diagnosis and prediction of pulmonary artery hypertension. (J Korean Pediatr Soc 2000;43:769 778)

beta-receptor antagonist as antihypertensive agent has adverse effect such as vasoconstriction, bronchoconstriction and aggravation of atherosclerosis. So beta-receptor antagonist with alpha-receptor blocking property has been studied for avoidance of adverse effects of beta-receptor antagonist. Nipradilol, a new beta-receptor antagonist with alpha-receptor blocking property was administrated in 30 essential hypertensive patients for 10 week in order to evaluate the antihypertensive effects and adverse effects. The results were as follows: 1) Nipradilol was effective in 20 patients(67%) on systolic blood pressure 22 patients (73%) on diastolic blood pressure at the end of 10 weeks treatment. 2)Before medication, mean systolic and diastolic blood pressure in sitting position were 160+/-14mmHg and 102+/-18mmHg,and after 10 weeks of medication, mean systolic and diastolic blood pressure were significantly declined to 143+/-22mmHg and 89+/-12mmHg(p<0.001). 3) There was no significant change in pulse rate, from 78+/-12 beats per minute the beginning of the treatment to 75+/-11 beats per minute after 10 week of treatment. 4) There was no significant changes in sodium, potassium, GOT, GPT, bilirubin, alkalin ephosphatase, BUN, creatinine, LDH, CPK and lipid. 5) The adverse effects of nipradilol were bradycardia(7%), dyspnea(3%), chest discomfort(3%) and headache(3%). In summary, nipradilol seemed to be effective antihyertensive drug in treating mild to moderate hypertension.

The authors made comparative studies of CT findings with upper GI series and surgical findings in 20 cases of histologically proven gastric cancers. The identification of thickening of gastric wall and local and remotemetastasis by CT was thought to be great value in treatment planning and prediction of prognosis of the patients. The results were as follows; 1. Of 20 cases, 19 cases demonstrated thickening of gastric wall. Among 3 cases suggested as early cancer on upper GI series, 2 cases demonstrated thickened gastric wall on CT and it was provedto be advanced cancer at surgery. 2. Out of 8 cases showed no definite metastasis on CT, 4 cases had malignant in filtration histologically in the regional lymph nodes. But they were less than 1.5 cm in diameter. 3. The frequency order of remote metastasis found by CT was pancreas, liver, left adrenal gland and lung in organs and retroperitoneal, regional nodes in lymph nodes.

CT was proved to be the most accurate diagnostic tool in the analysis of brain metastasis than any otherclassical methods. The authors studied CT findings of intracranial metastasis in 31 cases proven clinically andhistologically. The results were as follows; 1. Age distribution of the cases was 15 males and 16 females withpeak age of 6th decade in males and 4th decade in females. 2. Metastatic lesions were multiple in 18 cases andsingle in 13 cases. 3. The most common degree of edema was grade III, 43% of total metastatic foci. Markededematous low densities with relatively small nodular high densities in precontrast scan and variable contrastenhancement of the nodular densities were the most frequent CT findings. 4. No specific characterstics accordingto the primary cancer was noted. All four cases of choriocarcinoma showed hemorrhagic tendency.

Glycopyrrolate is frequently administered in combination with neostigmine to reverse a neuromus- cular blockade. The dosage was well established at 1/5 of neostigmine. But the authers have often observed a delayed manifestation of relative bradycardia after such a recommended dosage. This is not mentioned in the literature, but this may be due to an insufficient observation period. The authors monitored the change of pulse rate for 1 hour after the administration of the recom. mended dose. Further, the data wIns compared with that obtained after studies of lower and higher doses. The doses were 0.004, 0.008 and 0.012mg/kg of glycopyrrolate with 0.04mg/kg of neostigmine. 1) At all doses, bradycardia relative to the pre-reversal pulse rate was progressive until 30 minutes after injection. 2) As the glycopyrrate dose was increased the degree of bradycardia decreased (-24.7, -20.5, - 15.0 at 30 min.). 3) There was no difference in the immediate change in the pulse rate between the dcsages of 0.008 and 0.012 mg/kg. Change occured at 9 mins. 4) At dosages of 0.004 and 0.008 mg/kg, the pulse rates at 60 min were comparable to their ward pulses, but at a dosage of 0.012 mg/kg, the pulse rate was 8.5 beats/min higher.

Acute mobile thrombus of the abdominal aorta after chemotherapy is a very unusual finding, which can be a potential source of arterial embolism. We report here on a case of an acute mobile aortic thrombus with renal infarction. We successfully treated the patient with hybrid operation-open surgical and endovascular approach. Our case shows that hybrid treatment using wire-directed balloon catheter thrombectomy is a feasible, minimally-invasive treatment for a mobile aortic thrombus.
