Percutaneous extracorporeal life support (P-ECLS) is a useful modality for the management of refractory cardiac or pulmonary failure. However, venoarterial P-ECLS may result in a complication of left ventricular distension. In this case report, we discuss a patient with drug-induced dilated cardiomyopathy managed with venoarterial P-ECLS and a left atrial vent catheter. The venoarterial P-ECLS was modified to a paracorporeal left ventricular assist device (LVAD) by removing the femoral venous cannula. After 28 days of hospitalization, the patient was successfully weaned from the paracorporeal LVAD and discharged home from the hospital.

A 76-day-old infant weighing 3.4 kg was referred for surgical intervention for severe mitral valve stenoinsufficiency caused by leaflet fibrosis and calcification. He had ex perienced a cerebral infarction in the left middle cerebral artery territory, which was deemed attributable to an embolism of a calcified particle from the dysmorphic mitral valve. Because mitral valve replacement using a prosthetic valve was not feasible in this small baby, mitral valve replacement with a pulmonary autograft was performed. After a brief period of extracorporeal membrane oxygenation (ECMO) support, he was weaned from ECMO and was discharged home without further cardiovascular complications.

During the period from February to March, 1984, we employed a partial left heart bypass [left atrium to ascending aorta] in 2 patients who could not weaned from cardiopulmonary bypass with inotropic agents and cardiac pacing after coronary bypass surgery. These two patients showed significant improvement in ventricular function 18 to 47 hours after inserting the left heart bypass and were able to wean from the left heart bypass under using inotropic agents. Two patients died of multiple organ failures 11 days and 15 days postoperatively. These results indicate that early institution of left heart bypass in ventricular failure patients after open heart surgery can provide satisfactory long-term result.

Two experiments were conducted to determine the validity of the deuterium oxide ($D_2O$) dilution method to estimate milk intake by pigs. A total of 39 piglets weaned from their dams 24 - 36 hours after birth and trained to drink from artificial nipples, were used for two experiments. Estimates of milk replacer consumption of individual piglets over 1, 3, 5 and 7 days were made by the $D_2O$ dilution method and by dissappearance. Milk intakes estimated by this $D_2O$ dilution method were significantly correlated ($R^2$ = 0.98-0.99) with milk intake measured by disappearance. The average difference between estimates by disappearance and estimates by the $D_2O$ dilution method were -1%, +0.5%, +0.5% and -2.1% for measurement period of 1, 3, 5 and 7 days respectively.

We investigated the effects of vitamin E supplementation on lipid peroxidation and on the activities of antioxidative enzymes in kidney of KK mice of various age and duration of diabetes. Weaned KK mice were fed high fat a diet containing 20% corn oil(wt/wt), and were sacrificed at 4, 6, and 9 months of age. The high vitamin E diet consisted of the high fat diet supplemented with an excessive amount of dl-$\alpha$-tocopheryl acetate (2080 IU/kg diet) . In the diabetic groups, we found an increase in lipofuscin and decrease in antioxidative enzyme activities with aging. Treatment with vitamin E did not modify the level of fasting blood glucose. However, a significant decrease in lipofuscin and increase in antioxidative enzyme acitvities were observed in diabetic mice.

A 68-year-old man presented with a posterior tracheal wall injury caused by percutaneous dilatational tracheostomy. The wound was immediately covered with an absorbable polyglycolic acid sheet. Ten days after the injury, the perforation was closed with knotless sutures using a Castroviejo needle-holder through the tracheostomy. The successful repair in this case indicates the feasibility of the knotless suture technique for perforations. The technique is described in detail in this report. The patient was weaned from the mechanical ventilator on postoperative day 25. In cases of posterior tracheal posterior wall perforation, every effort should be made to repair the perforation through an existing opening.

Toluene is an aromatic hydrocarbon found in glues, cements, and solvents. It is known to be toxic to the nervous system, hematopoietic system, and causes acid-base and electrolyte disorders. Acute respiratory failure with hypokalemia and rhabdomyolysis with acute renal failure should be considered as potential events in protracted glue sniffing. We reported the case of 26-year-old woman was admitted to the emergency department with the development of respiratory failure and altered mentality due to hypokalemia after chronic glue sniffing. She was weaned from the ventilator 3 days later after potassium and sodium bicarbonate replacement and was discharged without respiratory symptoms and other complications.

Between January of 1980 and December of 1989, we are encountered 121 cases of Down syndrome here at Yonsei University Medical Center. of these being endocardial cushion defect, ventricular septal defect, tetralogy of Fallot, atrial septal defect, patent ductus arteriosus and complicated anomalies. The mean age was 1 month 2 years with the sexual division at 31 males and 29 females. Among these 60 patients, 10 of them were treated trough surgical management, 8 of them being open heart surgeries, the 8 open heart surgeries are broken down as follow: 4 total correction of ECD, 2 patch repair of VSD, 1 total correction of TOF, 1 patch repair of ASD secundum. Another 2 operative management are ligation of PDA and modified Blalock - Taussig shunt of TOF. Postoperatively all patients were weaned and extubated on an artificial ventilator without any respiratory complications, and were discharged without incident.

Genetic selection and sophisticated management technology have produced modern sows which excel in litter size and milk production. Recent research has identified nutritional innovations which may enhance productivity of the high producing sow. Selected research in three areas which have the potential to enhance reproductive performance are summarized in this report. First, preliminary evidence indicates that organic chromium may enhance litter size and conception rate. Secondly, high producing sows, particularly primiparous sows, required higher protein/lysine in late gestation and or lactation to optimize weaning weight and subsequent litter size. Valine and isoleucine, but not leucine, have been shown to enhance milk production. Phased feeding programs with diet cost partitioned toward gilts and away form parity 3 to 8 sows have been suggested as a means of improving reproductive performance in young sows. Lastly, recent research with sufficient sow numbers to document the effect of dietary fiber on reproductive performance has shown that sows fed fiber farrowed and weaned more pigs.

We investigated the effects of vitamin E supplementation on the protein glycosylation in vivo. Weaned KK-mice were fed high fat diet containing 20% corn oil(wt/wt), and sacrificed at 4, 6, and 0 months of age. High vitamin E diet was the high fat diet supplemented with an excess amount of 이-$\alpha$-tocopheryl acetate(2080IU/kg diet). We measured $HbA_{1C}$ as a glycosylation early product, and collagen-linked fluorescence (CLF) of skin as a glycosylation and product. We found that diabetic group had increased levels of $HbA_{1C}$ within 2 months after onset of diabetes and during the experiments. The skin CLF increased dramatically 5 months after onset of diabetics. Treatment with vitamin E did not modify the level of blood glucose. However, we observed a significant lowering in CLF and $HbA_{1C}$ in diabetic mice.
