Following TBI and ICH, administration of hBNP was associated with
improved functional performance as assessed by rotorod and Morris water maze latencies (p < 0.01). CBF was increased (p < 0.05), and inflammatory markers (TNF-alpha and IL-6; p < 0.05), activated microglial (F4/80; p < 0.05), and neuronal degeneration (Fluoro-Jade B; p < 0.05) were reduced in mice receiving hBNP. hBNP improves neurological function in murine models of TBI and ICH, and was associated with enhanced CBF and downregulation of neuroinflammatory responses. hBNP may represent a novel therapeutic strategy after acute CNS injury.”
“Background Aortic ischemia reperfusion (IR) is an important factor in the development of postoperative acute lung injury following abdominal aortic surgery The aim of our study was to selleck chemical examine the effect of beta glucan on lung injury Induced by abdominal aortic IR in rats\n\nMaterial and Methods Thirty two Wistar albino rats were randomized
into four groups (eight per group) as follows the control group (sham laparotomy), aortic IR (120 min ischemia and 120 min reperfusion), aortic IR + beta glucan (beta glucan 50 mg/kg/d for 10 d was administered orally before IR), and control + beta glucan Lung tissue samples were obtained for biochemical analysis Protein concentrations in bronchoalveolar Selleck ACY-738 lavage fluid and lung wet/dry weight ratios were measured Histologic evaluation of the rat lung tissues was also performed\n\nResults selleck products Aortic IR significantly increased the levels of MDA, superoxide dismutase, catalase, and myeloperoxidase (P < 0 05 versus control) Whereas, beta glucan significantly decreased
the lung tissue levels of MDA, superoxide dismutase, catalase, myeloperoxidase, (P < 005 versus aortic IR), and protein concentration in bronchoalveolar lavage fluid as well as wet/dry lung weight ratio Histologic evaluation showed that beta glucan attenuated tic morphological changes associated with lung injury\n\nConclusions The results of this study indicate that beta glucan attenuates lung injury induced by aortic IR in rats We propose that this protective effect of beta glucan is due to (1) reduced systemic inflammatory response, (2) reduced oxidative stress and lipid peroxidation in the lung tissue, (3) reduced pulmonary microvascular leakage, and (4) inhibition of leukocyte infiltration into the lung tissue (C) 2010 Elsevier Inc All rights reserved”
“Purpose Total pancreatectomy (TP) eliminates the risk and morbidity of pancreatic leak after pancreaticoduodenectomy (PD). However, TP is a more extensive procedure with guaranteed endocrine and exocrine insufficiency. Previous studies conflict on the net benefit of TP.
