Congenital pericardial defect is a rare anomaly, which was first described by M. Columbus in 1559. Four hundred years later the first clinical diagnosis was reported by Ellis et al. The congenital pericardial defect Is usually asymptomatic and Is found Incidentally at thoracotomy and autopsy, but it appears that partial absence of pericardium Is not Innocuous because of sudden death due to herniation of a portion of heart. We experienced congenital left pericardial defect in 20 year old female who was diagnosed as left ventricular aneurysm before operation. This patient complained of dyspnea on exertion and anterior chest discomfortness. Physical examination revealed Grade II pansystolic murmur on the 3rd and 4th intercostal space left sternal border. There were specific abnormal findings on the chest plain film, EKG, ultrasonography, and left ventriculography. On 9th July 1981, an operation was performed and found the left partial pericardial defect through which a large portion of left ventricle was herniated Into left pleural space. The method of operation was removal of adhesion and widening of the pericardial defect to avoid Incarceration. After operation, we observed marked Improvement of symptoms and disappearance of cardiac murmur.

A double aorto-coronary bypass procedure performed in 2 cases, one with a Prinzmetal`s variant angina and the other with an unstable angina, is presented. The patient with a Prinzmetal`s angina who had a high-grade obstruction of the left anterior descending and the right coronary system showed a marked postoperative improvement with complete disappearance of anginal pain. The other patient with unstable angina had obstruction of the left anterior descending as well as a marginal branch of the left circumflex artery. Following bypass of these vessels, the patient did well during the immediate postoperative period. However, he developed hypotension in the recovery room and died 6 hours postoperatively, in spite of an intensive effort at resuscitation. The most likely cause of death in this patient is a myocardial infarction.

Hypoplastic RV was rarely combined with various other intracardiac anomalies. We experienced the excellent result after surgical correction in these 2 patients. 1. F/7: Combined anomalies were, [1] Hypoplastic Rt. Coronary art.[2] Hypoplastic RV [3] ASD [secundum] & [4] PS [infundibular & valvular] After CP Bypass, [1] Direct suture of ASD [2] Infundibulectomy [3] Pul valvulotomy & [4] Patch enlargement of RVOT with Pericardial monocusp were done 2. F/14: Combined anomalies were, [1] Hypoplastic RV [2] P5 [infundibular] [3] T5 [4] VSD [Type II] [5] ASD [secundum] & [6] 2\ulcornerA-V Block fter CP Bypass, [1] Infundibulectomy [2] Tricuspid valvulotomy [3] Patch repair of VSD & ASD & [4] Implantation of permanent pacemaker were done. Above operations resulted in marked improvement with disappearance of cyanosis & dyspnea.

Thromboembolism is a major cause of morbidity and death following implantation of cardiac prosthetic devices. Effective systemic anticoagulation is very important. The presence of thrombus can often be detected by pulmonary edema associated with the disappearance of valve clicks. 2-D echocardiography and phonocardiography are also valuable tools. The most common treatment is reoperation and replacement after discovery early. We have experienced one death of fatal thromboembolism after St. Jude valve replacement was done in 48 years old male diagnosed of severe mitral stenosis. He was treated with warfarin, aspirin, ticlopidine for 10 weeks but died suddenly. At autopsy, valve dysfunction was seen due to organic thrombus arising from atrial septum and confirmed with microscopic findings.

Acute poisoning with organic solvents and other volatile compounds now usually follows deliberate inhalation (volatile substance abuse) or ingestion of these compounds. The effect of butane gas inhalation was analyzed for serum, liver, brain, lung and muscle. And the observations are revealed on rat cholinesterase activity, lactatedehydrogenase activity and electrophoretic pattern of lactatedehydrogenase isozyme. The results are as follows: 1. The rat cholinesterase activity on serum, liver and muscle show the decreased by increasing of inhalation time of butane gas in particular the lung cholinesterase activity was greatly affected. 2. Butane gas inhalation brought out the lactatedehydrogenase activity increased of the serum and the tissues and had an important effect especially in both the liver and muscle 1actatedehydrogenase activities. 3. Each tissue was found to have a characteristic distribution of lactatedehy-drogenase isozymes on celluloseacetate electrophoresis and the development of inhalation time is shown the disappearance and diffusion of band. The toxicity of butane gas inhalation was most prominence in the liver and lung toxicity was occurred also.

Atlantoaxial rotatory dislocation [AARD] is an uncommon disorder of childhood in which clinical diagnosis is generally difficult and often made late. It is very rare in adults because of the unique biomechanical features of the atlantoaxial articulation. We report a case of post-traumatic AARD in an adult. Reduction was difficult to obtain by skull traction and gentle manipulation. Therefore, the patient was treated surgically by an open reduction, transpedicular screw fixation, and posterior C1-2 wiring with graft. The normal atlantoaxial relation was restored with disappearance of torticollis. Postoperatively, the patient remains neurologically intact and has radiographic documentation of fusion. Atlantoaxial transpedicular screw fixation can be one of the treatment options for the AARD.

The research described in this paper was conducted to estimate the stability and heat budget in planetary boundary layer (PBL) at Kimhae. The upper air observation was carried out during period from 3 Februsry 1993 to 5 February 1993 at Kimhae. The surface observation data used the one during period from 1 April 1994 to 31 March 1995. The maximum height of inversion layer observed at Kimhae was 310 m. Destruction of the inversion was simultaneously occurred at the surface and the mid-layer (200 $\sim$ 300 m), however the origin of destruction is different each other. The surface inversion is destructed by surface heating owing to growing radiation in surface but disappearance of the mid-layer inversion is related to the upper cold air movement.

Endosulfan is a chlorinated pesticide; its persistence in the environment and toxic effects on biota are demanding its removal. This study aims at improving the tolerance of the previously isolated fungus Aspergillus niger (A. niger) ARIFCC 1053 to endosulfan. Released chloride, dehalogenase activity, and released proteins were estimated along with analysis of endosulfan degradation and pathway identification. The culture could tolerate 1,000 mg/ml of technical grade endosulfan. Complete disappearance of endosulfan was seen after 168 h of incubation. The degradation study could easily be correlated with increase in released chlorides, dehalogenase activity and protein released. Comparative infrared spectral analysis suggested that the molecule of endosulfan was degraded efficiently by A. niger ARIFCC 1053. Obtained mass ion values by GC-MS suggested a hypothetical pathway during endosulfan degradation by A. niger ARIFCC 1053. All these results provide a basis for the development of bioremediation strategies to remediate the pollutant under study in the environment.

We report two cases of patients with ruptured vertebral artery dissecting aneurysms that were treated using double overlapping stent placement. Angiography performed immediately after the procedure revealed a significant reduction of aneurysmal filling due to the intraaneurysmal thorombosis. In one case, complete disappearance of the lesion was observed after seven days and in the another one, the size of previous aneurysm sac was decreased on 7th post-procedure day. The reduced stent porosity caused by the overlapping stents, which result in significant hemodynamic changes inside aneurysmal sac, may accelerate intraanuerysmal thromobosis and may be helpful in achieving a more rapid complete occlusion of aneurysm. This double stent method may represent a therapeutic alternatives for dissecting vertebral artery aneurysm in which conventional endovascular techniques or stent supported coil embolization is not considered feasible and surgical treatment is contraindicated.

Effect of furosemide administration on glucose tolerance, insulin-and HGH response following parenteral glucose loading was studied in healthy subjects. Effects of potassium or calcium on the furosemide induced changes were also observed in the same subjects. Furosemide administration resulted in a considerable reduction in the magnitude and duration of insulin response although no obvious changes were observed in glucose disappearance from the circulation. Oral potassium or calcium supplement to the furosemide treated subjects showed a reversion toward normal of the insulin response. The author suggested that a decreased endogenous insulin production resulting from the potassium and/or calcium depletion is responsible for the changes observed. In those subjects who receive parenteral nutrition if administration of furosemide is essential, it should be supplemented by potassium and/or calcium.
