BACKGROUND: Liver transplantation (LT) is a complicated procedure with a high incidence of postoperative acute kidney injury (AKI). Previous studies indicate that even transient or mild post-LT AKI can result in critical conditions, including prolonged stays in hospitals and intensive care units and increased morbidity and mortality. The aim of this study was to investigate the association between body mass index (BMI) and occurrence of AKI in LT recipients. METHODS: Medical data from 203 patients who received LT surgery from January 2010 to August 2016 in a single university hospital setting were retrospectively collected and analyzed. Patients were classified as either underweight (BMI <20 kg/m²) or normal weight (20 ≤ BMI < 30 kg/m²). Demographic data, anesthetic methods, complications, and perioperative laboratory test values of each patient were assessed. Propensity analyses and logistic regression were performed to evaluate the association between BMI and post-LT AKI. RESULTS: There was no significant difference in occurrence of post-LT AKI between underweight and normal weight patients. The underweight patient group had significantly longer hospital stay compared with the normal weight patient group (P = 0.023). CONCLUSIONS: BMI classification was neither a positive nor negative predictor of postoperative AKI occurrence. However, patients with lower BMI had significantly longer hospital stay compared with their counterparts. Although our study was limited by its retrospective design, our observations suggest that lower BMI might play a role in post-LT AKI.

We evaluated the antitumor activity and toxicity of recombinant human interferon gamma (LBD -001) as a new modality for advanced renal cell carcinoma from March, 1988 to August, 1989 at the Department of Urology, St. Mary's Hospital, Catholic University Medical College. Eleven patients with advanced renal cell carcinoma were given recombinant gamma interferon at dose of 5.0-7.6 x 106U/day, subcutaneously three days per week. Among eleven patients, only one achieved partial response. Major adverse effects included fever, fatigue, myalgia and leukopenia, but no life threatening side effects were found. Although recombinant human interferon gamma have an antitumor activity against advanced renal cell carcinoma, further study is necessary to define the optimal treatment regimen.

OBJECTIVES: Cord blood stem cells have been widely used as donor cells for bone marrow transplantation recently. These cells can give rise to a variety of hematopoietic lineages to repopulate the blood. Recent observations reveal that some bone marrow cells and bone marrow stromal cells(MSCs) can grow to become either neurons or glial cells. It is, however, unclear whether or not there exists stems cells which can differentiate into neurons in the blood during the early stages of postnatal life. METHODS: Human cord blood stem cells were prepared from human placenta after full term delivery. To induce neuronal differentiation of stem cells, beta-mercaptoethanol was treated. To confirm the neuro-glial characteristics of differentiated stem cells, immunocytochemical stain for NeuN, neurofilament, glial fibrillary acidic protein(GFAP), microtubule associated protein2(MAP2) was performed. RT-PCR was performed for detecting nestin mRNA and MAP2 mRNA. RESULTS: We showed in this experiment that neuro-glial markers(NeuN, neurofilament, MAP2, GFAP) were expressed and axon-like cytoplasmic processes are elaborated in the cultured human cord blood stem cells prepared from new born placenta after full term delivery. Nestin mRNA was also detected in fresh cord blood monocytes. Conclusions: These results suggest that human cord blood derived stem cells may be potential sources of neurons in early postnatal life.

There has been numerous experimental liver transplantation models in the rodent : orthotopic versus hetrerotopic; whole liver versus partial liver; microvascular suture versus cuff method in technical aspects. Several simplified modifications were introduced for experimental liver transplantation for improving animal-survival rate. Liver transplantation without arterial reconstruction, the cuff tchnique or stent method were the examples of simplifing modification. In practice, complications related to biliary reconstruction are frequent causes of intraabdominal infection in our rat liver transplantation. Here we propose using simple liver transplantation model of partial heterotopic liver transplantation without artery and bile duct reconstruction in the studies which need only observation of immediate graft survival or very short-term follow-up. Here we examined the serial histologic changes of auxiliary liver grafts without biliary reconstruction during short period after transplantation. Until 7 days of transplantation, bile duct proliferation was confined in the portal area of grafts and did not distort the lobular structure. Early graft-survival and rapid immunologic response might be evaluated by this easy transplantation model.
