This study is intended to develop AE water reducing agent for reduction of bleeding and investigate its practical use. According to the results, fluidity and air content increases with an increase of superplasticizer and MC viscosity agent, AE water reducing agent for reduction of bleeding is developed after determining the ratio of superplasticizer and MC viscosity agent as 3:1 to satisfy the same fluidity and air content to conventional concrete and reduce bleeding amount. As the adding ratio of developed AE water reducing agent for reduction of bleeding increases, fluidity also increases, air content satisfies the aimed range, bleeding and sinking amount of concrete are reduced, and compressive strength is almost not different from plain concrete. Therefore, developed AE water reducing agent for reduction of bleeding satisfies the aimed air content in the range of slump 12~21cm, and can also reduce bleeding amount effectively without quality deterioration of compressive strength.

The authors tried to evaluate tumor occurrence in long-term dialysis patients with chronic renal failure. Among 359 patients, 20 patients (about 5.6%) were diagnosed with malignancy during long-term dialysis from the period of 1983 to 1995 at our nephrology department. The ultrasonographic and computed tomographic findings including the clinical features of 20 patients that were retrospectively reviewed. The mean age of the patients was 53 (37-75)years old and the ratio of male to female was 9:1. Among the 20 cases, 7 cases of hepatoma (35%) were developed. Among them, urinary tract tumors such as renal and bladder cancer were developed in 4 (20%) and 2 (10%) of the cases. Other malignant tumors were lymphoma, stomach cancer, uterine cervical cancer, cholangiocarcinoma, lung cancer, meningioma, and acoustic neuroma one case of each (each of 5.3%). The most common tumor in patients with chronic renal failure, who were receiving long-term dialysis, was hepatoma and the second most common tumor was cancer of the urinary tract such as kidney and bladder.

Hyponatremia is the most common electrolyte disorder in hospitalized patients, and incidence of hyponatremia is about 1-4%. It is suggested that hyponatremia is closely related with morbidity and mortality in these patients. Diuretic-induced hyponatremia is one of the most common causes of hyponatremia associated with hypovolemic hypoosmolality, but serious hyponatremia due to diuretic use is relatively uncommon. Advanced age may be a predisposing cause, and women is more susceptible than men, but no definite proof has been documented. The severity of symptoms can be roughly correlated with velocity and degree of hyponatremia, and neurological symptoms generally do not occur until the serum sodium falls below 125 mEq/L. Rapid development of hypoosmolality can result in brain edema before brain adaptation occurs by excreting intracellular solutes. In the most severe cases death can result from respiratory arrest after cerebral herniation. So, it is need to optimal treatment for neurological symptoms. We report a case of serious thiazide-induced hyponatremia in elderly hypertensive man which were aggravated by infusion of simple dextrose solution without electrolyte for severe watery diarrhea.

The incidence of bleeding complications may be decreasing. But, upper gastrointestinal(UGI) bleeding is a still significant complication of chronic renal failure(CRF). Although there are many controversies about clear cut guidelines for blood transfusion, blood transfusions are critically important and essential in many emergency cases. Recombinant erythropoietin has been used in the past in treatment of anemia in Jehovah's witness patients from surgery, chemotherapy, and trauma. We here report a case of the use of erythropoietin in Jehovah's witness patients with an active upper gastrointestinal bleeding and chronic anemia from end-stage renal disease. A 59-year-old male Jehovah's witness patient with a past medical history of diabetes mellitus and end-stage renal disease(receiving hemodialysis) was admitted because of hematemesis and melena. He was diagnosised with gastric ulcer on emergency gastroenteroscopy and treated with argon plasma coagulation. His hematocrit was 12.1% at admission. He refused blood transfusion and was treated with intravenous iron, ulcer medication and high dose erythropoietin. After 2 weeks, he was discharged with hematocrit 23%.

Multilocular cystic nephroma is a rare and non-inherited benign renal neoplasm occuring in the both children and adults. It is necessary to make a differential diagnosis from all renal diseases with a cystic component, such as simple cyst, metastatic renal tumor, cystic adenoma or angiomyolipoma in adults. We report a case of multilocular cystic nephroma presented with painful abdominal mass treated with laparoscopic nephrectomy and confirmed with pathology.

Patients with spontaneous pontine hemorrhage very often develop setvere disturbances of consciousness,pupilary abnormalities, respiratory and motor. They have high mortality rate. Therefore, I analyzed the correlation between the Glasgow outcome scale(GOS)and clincial manifestations or computed tomographic(CT)findings in 48 patients with spontaneous pontine hemorrhage to clarify factors predicting the prognosis. I examined 48 Patients with spontaneous pontine hemorrhage; 33 males and 15 females, age 54.6±8.99(mean±S.D.;range 39 to 68)brought to our hospital between January 1995 and December 1999, retrospectively. Correlations between the clinical manifestations, CT findings and the GOS was assessed with multivariate regression analysis. The results were as follow: 1) Patients with the pontine hemorrhage were of 8.8% in those with intracerebral hemorrhage. The ratio of male and female was 33 to 15. The incidence of age is eqial to 40,50 and 60. Total mortality was 41.6%. 2) The poor prognostic factor were that; Glasgow coma scale(GCS)3∼8, irregular respiration. pupilary abnormality, quadriplegia, Brain CT typeⅠ(massive), hydrocephalus, extrapontine extension, Intraventricular hemorrhage(IVH). These clinical analysis should be useful in determining the level of care and future resuscitative efforts.
