  • Potassium cardioplegia for myocardial preservation is being used extensively in open heart surgery. This study was designed to investigate the change in serum and urine potassium before, during, after the administration of cold blood potassium cardioplegic solution containing 28-30 mEq/L [28.6\ulcorner.56 mEq/L] of potassium chloride in 6 dogs. Total potassium dose used in the study was 14.9\ulcorner.89 mEq/L [1.2 mEq/Kg]. Mean potassium level in serum was within normal limits. Urinary excretion of potassium decreased during bypass but increased after bypass and eventually exceeded the amount of potassium infused as cold blood potassium cardioplegic solution. While cold blood potassium cardioplegia is a safe and efficient method of myocardial protection, postoperative potassium level must be observed carefully in order to detect obligatory potassium excretion following open heart surgery.

  • Dissecting aortic aneurysm of ascending aorta is a life threatening condition which requires prompt surgical correction. With deep hypothermic circulatory arrest and retrograde cerebral perfusion via superior vena cava, we could replaced ascending aorta in 4 cases safely. All of 4 cases; femoral artery, right auricle were used as cannulation site. The duration of circulatory arrest were 28, 30, 45, 60 minute in each cases and rectal temperature was 2$0^{\circ}C$ at that time. At the time of retrograde cerebral perfusion, we maintained central venous pressure under 25mmHg. We resected all of dissecting portion and replaced it with Hemashield graft. There were no deaths but two of four reoperated because of bleeding.

  • A 27-year-old man was admitted with a penetrating injury at the mid-manubrium. Computed tomographic (CT) angiography showed a f illing def ect in the aortic arch. This was evaluated as a sign of injury and the patient underwent an emergency operation. No active bleeding or clot was f ound in the mediastinum during the operation. The laceration point was between the innominate and the left carotid artery posteriorly. The injury was approached using hypothermic circulatory arrest. Aortotomy and exploration showed a 2-cm-long full-thickness aortic injury with an overlying clot. A filling defect on angiography as a sign of a penetrating arch injury has never been reported previously, but was the main pathological finding on CT angiography in our case. The aorta is a high-pressure system and injuries to it should be treated aggressively.

  • In Oriental medicine, different suggestions regarding how cerebrovascular accident(CVA) may develop have been offered by several physicians. In Jin(金)Yuan(元) dynasty, Liu Wan Su(劉完素) asserted that CVA was not developed by external PungSa(風邪) but internal HwaYul, which was noted in the "SoMunHyunKiWonByungSik". To verify experimentally Liu's HwaYul theory in rats, normothermic control group (37$^{circ}C$) and hypothermic test group (32$^{circ}C$) were subjected to transient middle cerebral artery occlusion(MCAO) of 1hour. In 7days after MCAO, the rats were sacrified and the volume of infarct and the size of edema were measured. The present findings expand our understanding of the pathophysiology as to the CVA which is related to the HwaYul theory.

  • Between April, 1986 and July, 1991, 477 patients underwent open heart surgery with hypothermic cardiopulmonary bypass. There were 242 patients [50.7%] of acyanotic congenital anomalies, 34 patients [7.1%] of cyanotic congenital anomalies, and 187 patients [39.2%] of acquired heart diseases, 8 patients [1.7%] of coronary artery diseases, and 6 patients [1.3%] of mixed anomalies. Among the 276 congenital cardiac anomalies, 147 patients [53.3%] were male and 129 patients [46.7%] were female, ranged in age from 2 years to 58 years. Among the 187 acquired heart diseases, 72 patients [38.5%] were male and 115 patients [61.5%] were female, ranged in age from 10 years to 68 years. The common congenital defect were VSD and ASD in acyanotic cardiac patients, and TOF in cyanotic cardiac patients. Among the 187 acquired heart diseases, 180 patients underwent operation for cardiac valvular diseases, 4 patients were resected left atrial myxoma, and 3 patients underwent operation for aortic regurgitation with ascending aortic aneurysm. The operative mortality rate was 1.2% in acyanotic cardiac patients, 11.8% in cyanotic cardiac patients, and 6.9% in acquired cardiac patients, with overall mortality rate 4.2%.

  • A 73-year-old woman who underwent combined bioprosthetic mitral valve replacement, tricuspid ring annuloplasty, and coronary artery bypass grafting 12 years previously visited our clinic due to aggravated dyspnea caused by structural valve deterioration of the mitral prosthesis. Because aortic or femoral artery cannulation and cross-clamping would have a high risk of stroke owing to severe calcification of the ascending aorta and ilio-femoral vessels, and because there was a risk of redo sternotomy due to the patent bypass grafts, a comprehensive approach including axillary artery cannulation, a minimally invasive right thoracotomy approach, and a clampless hypothermic fibrillatory arrest technique was used during redo mitral valve replacement.

  • The general pharmacological tests with rhGM-CSF indicated that it had no influences on rotarod and locomotor activity tests, but shortened hexobarbital-sleeping time at the large dose of 3 mg/kg s.c. in mice. It elicited no hypothermic, analgesic and antiepileptic action. No influences on blood pressure and respiration in rabbits were observed at the dose of 1 mg/kg, i.v. and it did neither affect the receptors of adrenaline, acetylcholine, serotonin, histamine, kinin and oxytocin, nor antagonize the actions of histamine, serotonin and oxytocin at its concentrations of 1$\times$$10^{-6}$g/ml. However, this substance was demonstrated to stimulate the formation of leucocytes in rats.

  • Aspalatone [3-(2-methyl-4proponyl)]-2-acetyloxybenzoate, CAS 147249-33-0) is a compound having an antithrombotic action. General pharmacological properties of aspalatone were studied. Aspalatone had no effect on central nervous system and no anticonvulsant effect up to 1200 mg/kg p.o. However, the compound has hypothermic and analgesic effect. When administered intravenously in rabbits, aspalatone did not affect blood pressure, heat rate and respiration rate and depth, and it did not inhibit transient hypotensive effect of acetylcholine. The compound did not affect isolated guinea-pig ileum and tracheal strip at a concentration of 1${\times}$$10^{-4}$, and did not inhibit histamine-induced contraction of guinea-pig ileum. It also did not affect isolated rat stomach fundus and estrogenated rat uterus at 1${\times}$$10^{-4}$, and did not inhibit contraction produced by acetylcholine or oxytocin. The pupil size and intestinal propulsion were not influenced at a large dose of was shown. The compound showed a slight increase in urine volume and led to decreased excretion of potassium in urine of rats. The results suggest that aspalatone may have no considerable adverse effects in general pharmacological aspect.

  • A ginseng preparation (GP) consisting of ginseng ex., lycium fructus ex., four kinds of vitamines and caffein was evaluated for acute toxicity and general pharmacology. Average lethal doses $(LD_{50})$ of GP in male mice were 2,988mg/kg (i.p.) and more than 3g/kg (p.o.). In dosage of 300 and 900mg/kg (p.o.) showed no analgesic activity in both tests of the writhing method induced by acetic acid and of tail pressure method and no effect on the pentetrazole-induced convulsion. However, it appeared to have a hypothermic action only in dose of 900mg/kg. The duration of hypnosis induced by hexobarbital sodium in mice was shortened by GP, being probably due to caffein. GP Produced no marked contraction of isolated ileum and uterus in high concentrations of up to $1{\pm}10^{-3}g/ml$. These results suggested that GP did not show any considerable central nervous depressant activity and exhibited very weak actue toxicity in mice.
