INTRODUCTION: Colloids and crystalloid are used during cardiac surgery for priming of the cardiopulmonary bypass (CPB) circuit. Colloids may decrease postoperative fluid balance because of their high oncotic pressure and low risk of fluid extravasation. On the other hand, colloids have been shown to impair blood coagulation. MATERIALS AND METHODS: In a prospective, randomized, double-blinded study, 50 patients scheduled for coronary artery bypass grafting or a valve procedure were planned to be randomized to receive either balanced 6% HES130/0...

Many AML-associated chromosomal abnormalities, such as t(8;21), t(15;17), inv(16), t(9;11), t(9;22) and t(6;9) are well known. The chromosomal aberration of t(16;21)(p11;q22) in AML is rare and it is known to be associated with poor prognosis, young age (median age, 22 yr), and involvement of various subtypes of the French-American-British classification. We report here 2 AML patients with t(16;21)(p11;q22), proved by conventional cytogenetics and/or reverse transcription (RT)-PCR. Erythrophagocytosis by leukemic blasts was observed in both of the cases...

OBJECTIVES: Cytomegalovirus (CMV) infection has been suggested to accelerate beta-cell destruction and thereby to contribute to new-onset diabetes and failure of islet allografts in both humans and rodents. Surprisingly, direct CMV infection of beta cells has received only minor attention. Therefore, we investigated the susceptibility of rat beta cells for rat CMV (RCMV) infection and the direct effects on the regulation of immune cell-activating ligands. METHODS: Primary rat beta cells, the rat beta-cell line Rin-m5F, and fibroblasts were RCMV-infected in vitro...

We co-transplanted silica gel-entrapping 4H-1,3-Thiazin-2-amine,5,6-dihydro-6-methyl monohydrochloride (AMT) with islets to evaluate the effects of AMT on early graft dysfunction in a syngeneic mouse model. The mean diameter of AMT-embedding silica gel particles was 595 +/- 275 nm. The cumulative release of AMT was 29% at 1 hour and 45% at 72 hours. Sixteen streptozotocin-induced diabetic mice were separated into 3 groups. Group A received 50 islets (n = 4). Group B received 50 islets and blank silica gel (n = 6)...

Mycophenolic acid (MPA)-induced beta-cell toxicity is an important factor for islet graft function. The signal transduction mechanisms underlying this process have not been fully explored. Using a proteomics approach, we examined protein expression patterns in MPA-treated RIN-5 cells and found that RhoGDI-alpha expression is altered by MPA-treatment. We examined the relationship between RhoGDI-alpha expression and activated JNK during MPA-induced apoptosis. Cells were treated with N-acetyl-cysteine (NAC), caspase inhibitor, JNK inhibitor, guanosine or GTP for 1 h before being treated with MPA...

During pancreatic islet transplantation, delayed and insufficient revascularization can deprive islets of oxygen and nutrients, resulting in cell death and early graft failure. Deferoxamine (DFO), an iron chelator, increases vascular endothelial growth factor (VEGF) expression in cells. The aim of this work was to study the effect of DFO on beta-cell and pancreatic islet viability as well as VEGF expression. beta-cell lines from rat insulinoma (Rin m5f) and primary cultures of pancreatic islets from Wistar rats were incubated with DFO (10, 100, and 1000 micromol/L)...

One of the main problems of microsurgery for lymphedema consists of the discrepancy between the excellent technical possibilities and the subsequently insufficient reduction of the lymphoedematous tissue fibrosis and sclerosis. Appropriate treatment based on pathologic study and surgical outcome have not been adequately documented. Over the past 25 years, more than 1000 patients with peripheral lymphedema have been treated with microsurgical techniques. Derivative lymphatic micro-vascular procedures has today its most exemplary application in multiple lymphatic-venous anastomoses (LVA)...

The purpose of this investigation was to measure vascular input impedance in infrainguinal vein grafts and assess the importance of clinical and hemodynamic parameters in predicting graft patency. Fifty-seven patients undergoing infrainguinal vein bypass grafting for limb salvage (n = 40) or claudication (n = 17) were prospectively studied. At the time of revascularization, simultaneously acquired intraluminal pressure and blood flow waveforms were digitized at 200 Hz and subjected to Fourier transformation in near real-time...

Cytokine induced pancreatic beta-cell destruction seen in Type 1 diabetes and islet graft rejection involves multiple intracellular signaling pathways that directly or indirectly lead to inflammatory damage or programmed cell death. IL-1beta has been shown to stimulate the 12-lipoxygenase pathway product 12-HETE, in RIN m5F cells; however, the precise role of 12-LO activation in mediating cytokine effects is not clear. Since the stress-activated protein kinase, JNK, has been linked to cytokine mediated inflammatory actions, we studied the effect of two LO products, 12-HETE and 15-HETE, on JNK activity...

We report propagation of human papillomavirus (HPV) type 11 in human xenografts in the severe combined immunodeficiency (SCID) mouse and compare this new animal model for HPV infection to the previously established athymic nude mouse model. HPV-11-infected foreskin fragments grafted under the renal capsule of SCID mice formed large epithelial cysts that had the histologic and immunocytochemical features of HPV infection. This infection was successfully passaged to nude mice. Viral particles that reacted to an antibody directed to HPV-11 virions were identified from samples recovered from the SCID and nude mice...

A 63-year-old male with the left parotid gland carcinoma was operated with the reconstruction of the left carotid artery after the left radical neck dissection. The greater saphenous vein was used for the vein graft between the left common carotid artery and the medial cerebral artery. Postoperatively, a temporary loss of consciousness and a half body paresis of the contralateral side occurred, but they were recovered completely in 12 hours. Postoperative angiography showed a good blood flow in the reconstructed vessel...

The multipotent embryonal carcinoma (EC) P19 cell line differentiates into neurons, glia and smooth muscle following exposure to retinoic acid (RA). RA-induced differentiation is irreversible and the neurons that develop are abundant, post-mitotic, and survive for prolonged periods in culture or when grafted into the CNS of adult rats. Striatal slices containing grafted P19 cells were studied with intracellular recording and labelling techniques to examine the development of electrophysiological and morphological properties of P19-derived neurons over a period of 6 to 120 days after grafting into ibotenic acid lesioned striatum...

Fibroblastic 3T3 and endocrine RIN cells were genetically modified by infection with a recombinant retrovirus encoding the form I of human tyrosine hydroxylase (TH) and selection in tyrosine-free medium. These cells were grafted to rats unilaterally lesioned with 6-hydroxy-dopamine. Both cell types survived implantation into the striatum, expressed TH immunoreactivity, and as assessed by microdialysis 8-9 days after implantation, secreted high amounts of DOPA and/or dopamine into the surrounding host striatum...

One of the most important determinants of graft patency is the degree and character of vascular outflow. This study was designed to evaluate input impedance as a functional assessment of the outflow bed of vascular grafts. Four distinct outflow environments were created for external jugular vein conduits in 42 New Zealand white rabbits. Vein grafts (n = 14) were fashioned as end-to-side common carotid interposition bypass grafts. Arteriovenous fistulas (n = 15) were created by side-to-side anastomosis of the distal common carotid artery and linguofacial vein...

The relative importance of synaptic versus paracrine dopamine transmission for the occurrence of functional effects following intrastriatal grafting is not fully established. In the present study we grafted cell lines, expressing the form I of human tyrosine hydroxylase after infection with a recombinant retrovirus and selection in tyrosine-free-medium, to the denervated striatum in order to analyse the extent to which extracellular dopamine levels can be restored and the effect of a diffuse release of dopamine on motor impairement in a rat model of Parkinson's disease...
