Influence of sulphur hot spring water upon wound healing of rat skin was studied. To provide local inflammation, croton oil was injected intradermally into a previously shaved area of rat abdominal skin. Those rats were taken bath with sulphur hot spring water at 37°C for 10min a day, every second day. The increased ratio of hexosamine to hydroxyproline was observed in skin necrotized with croton oil at 4th day, because of increases in hexosamine and decreases in hydroxyproline concentrations with inflammation. After that, hexosamine and hydroxyproline concentrations of necrotic skin returned to control, uninjured levels in 10 days. In bathing with sulphur hot spring water, changes in hexosamine and hydroxyproline concentrations of necrotic area did not alter to bathing with deionized water and to non-bathing of rats.
Although influence of bathing with sulphur hot spring water was examined on glutathione metabolism in rat liver and kidney, it was observed that reduced glutathione concentration, and GSH-reductase, GSH-peroxidase and γ-glutamyl transpeptidase activities unchanged in liver and kidney for the bathing period of 14 days.

The effect of oral administration of sulphur hot spring water on chronic liver damaged rat was studied. The liver damaged rats were produced by injection of carbon tetrachloride (150l of CCl₄ per 100g of body weight) twice a week. Sulphur hot spring water was administrated ad libitum as drinking water throughout experimental period. At 40 and 88 days, rats were sacrificed for histological and biochemical examinations.
When tap water was administrated to CCl₄-poisoning rats for 88 days, extensive vacuolar degeneration of parenchymal cells were observed in liver. While in administration of sulphur hot spring water, there were mild vacuolar degeneration in parenchymal cells of liver.
Although GSH content and GSH-peroxidase activity of liver unchanged in CCl₄-poisoning, and were unaffected with administration of sulphur hot spring water, GSH-reductase activity increased with administration of sulphur hot spring water for 88 days. The increased lipoperoxide and hydroxyproline in liver with CCl₄-poisoning were slightly lowered by administration of hot spring water.
In plasma, furthermore, LDH, GPT and GOT activities which increased markedly by CCl₄-poisoning decreased strikingly by administration of hot spring water at 88 days. Whereas ALP, CE and LAP activities little changed by CCl₄-poisoning, and were scarcely affected with administration of hot spring water. Among other plasma components, though total cholesterol and cholesteryl ester levels decreased by CCl₄-poisoning, those levels were not sustained with sulphur hot spring water administration.

Ten patients, aged 3 to 43 years, with the tetralogy of Fallot underwent in situ pulmonary valve replacement (PVR) 13 times. The implanted valves were a St. Jude Medical prosthesis (3 times) and a bioprosthetic valve (10 times). In 5 patients PVR was performed at the time of radical repair and in the remaining 5 patients PVR was performed after radical repair. Three patients underwent re-PVR at 6 to 13 years after the first PVR. There was one operative death in re-PVR 14 years after the first PVR and one patient died from congestive heart failure 4 years after PVR. In the patients with the tetralogy of Fallot, the rate of PVR in those who had undergone open Brock's operation were significantly higher than that of the patients without open Brock's operation (p<0.05). Actuarial survival rates at 5 years and 10 years were 88.9% and 88.9%, respectively. Rates of freedom from reoperation at 5 years and 10 years were 88.9% and 59.3%, respectively. Although the early operative results are satisfactory, re-PVR is mandatory in the future. Thus the indications of PVR should be considered carefully.

In a 63-year-old male patient Jehovah's witness, IABP was introduced due to acute myocardial infarction and cardiogenic shock, and PCI (BMS) was carried out to CAG #7 100%. Stent placement was carried out and his hemodynamics stabilized. A left-to-right shunt was observed upon carrying out LVG, so the patient was referred to our hospital for surgery purposes due to a diagnosis of ventricular septal perforation (VSP). Upon transferring the patient to hospital, his PA pressure elevated to 53 mmHg although the blood pressure was maintained, and no findings of right heart failure were observed. His respiratory condition was stable. Emergency surgery was considered, but the patient was taking Clopidogrel following PCI, and so VSP repair (extended endocardial repair) was carried out following 4 days discontinuation of Clopidogrel. Preoperative anemia was not observed ; however, postoperative hemorrhagic anemia improved due to iron preparation administration, and the patient was discharged from hospital 22 days following surgery without blood transfusion.

We report a rare case of primary cardiac angiosarcoma in the right atrium. A 47-year-old man was admitted to our hospital with cardiac tamponade. Echocardiography and computed tomography revealed a tumor in the right atrial cavity. We performed tumor resection to confirm the histological diagnosis, to prevent tumor embolism, and to increase the possibility of improving the prognosis. The tumor was resected with the right atrial wall and right pericardium. The right atrium was then reconstructed with a bovine pericardial patch. The pathological diagnosis was angiosarcoma. The patient survived only about 6 months after surgical resection, but there was no local recurrence. This report presents a very rare case of cardiac angiosarcoma associated with cardiac tamponade.
