Percutaneous transplant kidney biopsy has become the most important tool for diagnosing allograft dysfunction. However, renal biopsy has various complications. Among them, hemoperitoneum is a rare complication and has not been reported in Korea. We experienced a case of hemoperitoneum after transplant kidney biopsy. A 43-year-old man, 3 years after renal transplantation, was presented with elevated serum creatinine. Percutaneous renal biopsy was executed by real-time ultrasound guidance and 14-gauged spring loaded automated biopsy gun at upper pole of transplanted kidney. Renal biopsy was completed after 5 trials due to poor visualization of biopsy needle tip. After 2 hours, the patient complained of acute right side abdominal pain and dizziness. Abdominal pelvis CT showed moderate amount of hemoperitoneum. The patient underwent emergency laparotomy. Hematoma was seen in the omentum with minor vessel bleeding. Ligation was done. The patient was discharged after 15 days.

A 67-year-old male patient had coronary artery bypass graft. Before the induction of general anesthesia, 16 gauge central venous catheter was inserted via left subclavian vein. Initial chest anteroposterior (AP) radiograph showed adequate position, and the central venous pressure measurement through it was satisfactory. This patient's progress was satisfactory, and he was extubated on the second postoperative day. Daily chest AP radiograph had been unremarkable until the third postoperative day, when a right-sided pleural effusion was seen. A day later, the patient complained severe chest pain and dyspnea. We suspected perforation of superior vena cava wall by tip of central venous catheter on the chest computerized tomograph (CT). The injection of radiopaque dye through the central venous catheter confirmed spillage into the mediastinum on the chest CT. Right chest tube was inserted. The patient's condition dramatically improved after chest tube insertion. (Korean J Anesthesiol 2002; 43: 525~530)
국내산 Kaolinite 로부터 중기공성 γ-Alumina from Domestic Kaolinite
김윤섭,조형찬,고형신 한국공업화학회 2000 응용화학 Vol.4 No.1
The mesoporous γ-A1₂O₃ prepared by selective leaching of calcined domestic kaolinite has been studied, γ-A1₂O₃ prepared from kaolinite calcined at 950℃ for 24hrs followed by leaching with 1-4 mole KOH solutions at 50-90℃ for lhr had specific surface areas as high as 150-250㎡/g and average pore diameter of 65Å. The specific surface areas and total pore volumes increased gradually with temperature and concentration of KOH solution.
