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.

A 65-year-old female patient visited our clinic complaining of multiple skin lesions since one year ago. There were yellowish to brownish colored, bean to walnut-sized nodules on both lower extremities. Dylon stain with polarizing microscopy, immunohistochemical stain to amyloid P and immunoglobuhn-kappa chain showed positive reactivities but keratin stain was negative. According to histopathologic and immunohistochemical findings, she was diagnosed as nodular amyloidosis.

Bromidrosis is a disorder characterized by rancid body odor which influences a patient's social life and mental health. The therapeutic modalities and the mechanism of bromidrosis have been carefully studied, however, there have been few reports about the genetic inheritance of bromidrosis. We investigated the family history of 42 patients who were operated on for bromidrosis and followed up to the third generation in 10 cases. The results were as follows: Results of investigation which were followed up the second generation. The fathers of five patients and the mothers of 11 patients had bromidrosis in 18 male patients. The fathers of six patients and the mothers of 12 patients had bromidrosis in 24 female patients. Thirty-four patient (81.0%) among a total of 42 have a single parent with bromidrosis. Result of investigation which were followed up to the third generation Bromidrosis was occurred in 17 of 42 patients (40.5%) in the second generation, and 18 of 27 patients (66.7%) in the third generation. In one case, a father transmitted bromidrosis to his three sons, and as a result, X-linked inheritance could be ruled out Bromidrosis was not skipped in every generation of all families. We on conclude that bromidrosis is an autosomal dominant inherited disorder.

PURPOSE: inhaled nitric oxide(iNO) is an excellent method for the postoperative pulmonary hypertension in congenital heart disease. But more detailed care is needed because of the development of rebound pulmonary hypertension after NO Withdrawal. We performed this study in order to discontinue the iNO successfully by way of presenting the adequate weaning and supplying methods. METHODS: Between January, 1998 and August, 1999 we sudied 10 patients who had rebound pulmonary hypertension(RPH) after iNO withdrawal. We completed the iNO in these patween the first the second trial of the weaning process. We tried to discover the differences between the first and second weaning process. We measured NO concentration at the start and just before NO withdrawal and during the period of weaning process. Moreover, to identify the iNO effects during the weaning of the iNO, we counted the degree of the change of PaO2/FiO2and mean PAP/SAP beween initial and at half of the initial NO concentration. RESULTS: Second weaning had a longer duration weaning process(11+/-0 cersus 5+/- hours, P<0.05), lower NO concentration just before NO withdrawal(2+/-.6 versus 4+/-ppm, P<0.05). In the change of the mean PAP/SAP and PaO2/FiO2as iNO was weaning from the initial iNO concentration to a half of the initial iNO concentration, the degree of increase in mean PAP/SAP(0.026+/-.07 versus 0.054+/-.07, P<0.05) and the degree of decrease in PaO2/FiO2(49+/-4 versus 65+/-2, P<0.05) were smaller in the second in the second weaning process than the first weaning process. CONCLUSION: A successful weaning of iNO can be performed with a low iNO concentration at the start and just before withdrawal and with the long duration iNO weaning process. Moreover, We speculate that the degree of change in the mean PAP/SAP and PaO2/FiO2at the half of the iNO weaning process are an indicator for the development of RPH.

9.Protective Effects of Fenofibrate Against the Inflammatory Cytokines in Lipopolysaccharide-Induced Mice Brain Tissues.

BACKGROUND: Increasing evidence suggests that the entry of proinflammatory factors into the brain induces the activation of microglia, astrocytes, and oligodendrocytes and then produces the more proinflammatory cytokines and reactive oxygen species that can ultimately lead to neuronal death. This has clinical implications and provides a link between periperal inflammation and neuroinflammation. Peroxisome proliferator-activated receptors (PPARs), a member of the nuclear hormone receptor superfamily, has been implicated in the regulation of immunity and inflammation in rodents and humans. The objective of this study was to investigate whether the increased expression of PPAR with fenofibrate treatment was altered in the immune system of mice brain tissue after Lipopolysaccharide (LPS) was injected intraperitoneally. METHODS: PPARs expression was investigated in the brain tissues of BalB/c mice (n=6) under four situationssterile saline injection (control), LPS injection to generate periperal inflammation, LPS injection (5 mg/kg) with pretreated fenofibrate, and fenofibrate injection (100 mg/kg). RESULTS: Fenofibrate has protective effects against the increase of LPS-induced proinflammatory cytokines including interleukin (IL)-1beta, IL-6, and tumer necrosis factor-alpha in serum and brain tissue, measured using the enzyme linked immunosorbent assay, reverse transcriptase-polymerase chain reaction, and Western blot analysis. Also fenofibrate pretreatment markedly suppressed the reduction of PPARs mRNA and protein level by LPS injection. Moreover, the increased activation of PPARs abrogated the reduction of ABCD3, ACOX1, and catalase expression leading to an increase in the antioxidative capacity in brain tissue blocking the production of lipid peroxidation after LPS administration. CONCLUSION: The antiinflammatory and antioxidative properties of fenofibrate may be useful in ameliorating the progression of neuronal diseases.

Adult intussusception is rare involving of only 1% of the causes of bowel obstruction. We report a case of a 39-year-old female with intussusceptions due to inverted Meckel's diverticulum. She visited our hospital for diffuse abdominal pain during 1 week and aggravated abdominal pain for 2 days. Vital signs were stable, and there was periumbilical tenderness. She had no history of abdominal operation. CT scan showed a 3.7x2.1 cm of fatty mass with focal intussusception in the distal ileum. When the emergency operation was performed, the patient was found to be suffering from ileocolic intussusception. A manual reduction of intussusception showed inverted Meckel's deverticulum at 65 cm proximal to the ileocecal valve, and the segmental resection of small bowel including a Meckel's diverticulum was performed. Pathologic examination revealed a Meckel's diverticulum containing a 0.6x0.6 cm sized aberrant pancreas.
