“Aim:  Current medical transplantation methods focus on solutions for major problems such as the shortage of donors. To overcome these issues, expanding organ preservation time has become a major concern. A new refrigerating chamber has been recently developed, which can cool the inside of a material to the required temperature by frequently sensing the temperature of both inside and surface of the materials. selleck kinase inhibitor The purpose of this study is to evaluate the usefulness of a

Temsirolimus new refrigerating system in hepatic preservation. Methods:  The liver grafts were harvested from rats and divided into two groups. Group A consisted of grafts preserved in chilled University of Wisconsin solution (UW) solution (on ice) for 24, 72 and 168 h. Group B consisted of grafts preserved in the UW solution in a new refrigerator at 4°C. Results:  In group B, aspartate aminotransferase released into effluent after cold storage for 72 h showed a marked decrease compared to group A (P < 0.05). The levels of ammonia and lactate decreased significantly in group B (P < 0.05). In group B, the levels of adenosine triphosphate were significantly preserved after cold storage for 24 h and 72 h compared to group A (P < 0.05). Immunohistochemistry showed positive cells for heme oxygenase-1 were significantly increased in group B after cold storage. Conclusion:  This new refrigerator can improve preservation injury of hepatic grafts and may provide an innovative technique for liver transplantation. "
“Background and Aim:  Inflammatory bowel disease (IBD) is a multi-factorial disease with an unknown etiology characterized by oxidative stress, leukocyte infiltration and a rise in inflammatory cytokines. This study was

conducted to investigate lithium in 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced chronic model of experimental IBD, and the contribution of potassium channels as a possible underlying mechanism. Methods:  Experimental IBD was induced in rats find more by a single colonic administration of 10 mg of TNBS. Lithium, Glibenclamide (a potassium channel blocker), Lithium + Glibenclamide, Cromakalim or Lithium + Glibenclamide + Cromakalim were given twice daily for 7 successive days. At the end of the experiment, macroscopic and histopathologic scores, colonic malondialdehyde (MDA), tumor necrosis factor-α (TNF-α) level, and myeloperoxidase (MPO) activity as well as plasma lithium level were assessed. Results:  Both macroscopic and histological features of colonic injury were markedly ameliorated by lithium. Likewise, the elevated amounts of MPO and MDA were diminished as well as those of TNF-α (P < 0.05).
