蛋白质Z与动脉粥样硬化性脑梗死的相关性

目的 观察蛋白质Z（Protein Z,PZ）在动脉粥样硬化性脑梗死（Atherosclerotic cerebral infarction,ACI）患者急性期内的变化,分析PZ与D-二聚体（DD）、纤维蛋白原（FIB）在ACI患者中变化的相关性及血浆PZ的检测在ACI患者中的诊断价值及临床意义.方法 病例组选择发病在72h之内的ACI患者;对照组来自本院健康体检者.所有受检者均于入院即时及入院第14天抽取静脉血测定PZ和相关血凝因素等资料.另采用头颅CT或MRI测量与症状和体征相对应的最大低密度影面积,以及美国国立卫生研究院卒中量表（NIHSS）进行神经功能缺损评分.结果 ACI患者发病3d内血浆PZ、DD、FIB水平明显高于对照组;入院第14天所测的PZ、DD明显高于入院即时所测水平;在诊断ACI的过程中PZ的曲线下面积（AUC）、灵敏度和特异度均高于其他凝血因素,ACI患者血浆PZ浓度与梗死面积及NIHSS评分无相关性.结论 本研究证实了ACI急性期患者体内存在凝血-纤溶系统异常;PZ是脑梗死的一个的危险因素;通过对ACI急性期患者血浆PZ水平及其他血凝因素的检测,结合临床症状、体征及影像学检查,有助于对ACI的诊断和对病情作出判断.     

Dietary clofibrate inhibits induction of hepatic antioxidant enzymes by chronic estradiol in female ACI rats

Excess production of H₂O₂ has been implicated in oncogenesis. The object of the present study was twofold: first, to determine the influence of chronic estradiol (E₂) on the activities of selected hepatic antioxidant enzymes in female ACI rats, a strain that is highly sensitive to the induction of estrogen dependent mammary tumors; secondly, to evaluate the actions of dietary clofibrate, a peroxisome proliferator, on activities of these enzymes in control and E₂-treated ACI rats. Enzymes selected for study were: NAD(P)H quinone oxidoreductase (NQO1), glutathione S-transferase (GST) and glutathione peroxidase (GPx). Cytosolic catalase (CAT) was also measured as an index of peroxisome proferation in control and E_2- treated animals. E₂ was administered chronically over 6 and 12 week periods from cholesterol pellet implants containing either 1 or 3 mg E₂. Animals were fed AIN-76A diets with or without 0.4% clofibrate over the experimental period. NQO1 and GST but not GPx were induced to varying degrees (NQO1 about 300%, and GST about 45–97%) by chronic E₂-treatment. E₂-induced increases in these activities were completely prevented in rats exposed to dietary clofibrate. Dietary clofibrate also caused slight but significant reductions in baseline activities of NQO1, GST and GPx in control animals. Serum E₂ levels, increased approximately 540% in a dose-dependent manner, and were not altered by dietary clofibrate. It is concluded that chronic E2 treatment markedly induces several important hepatic antioxidant enzymes in female ACI rats, and induction of these activities by E2 is inhibited completely by dietary clofibrate. Both of these actions have the potential to markedly influence the profile of E₂ metabolites exported from the liver to E₂ sensitive extrahepatic tissues and influence the initiation and progression of hormone-dependent tumors.

Gentamicin and leucine inhalable powder: What about antipseudomonal activity and permeation through cystic fibrosis mucus?

The aim of this study was to evaluate the permeation properties of gentamicin (G) in a novel dry powder form for inhalation through an artificial mucus model. Moreover, since respiratory infections sustained by Pseudomonas are a major cause of sickness and death in CF patients, the susceptibility of P. aeruginosa to engineered G powders was investigated.

Allogeneic administration of fetal membrane-derived mesenchymal stem cells attenuates acute myocarditis in rats

We reported previously that the autologous administration of bone marrow-derived mesenchymal stem cells (BM-MSC) significantly attenuated myocardial dysfunction and injury in a rat model of acute myocarditis by stimulating angiogenesis and reducing inflammation. Because BM aspiration procedures are invasive and can yield low numbers of MSC after processing, we focused on fetal membranes (FMs) as an alternative source of MSC to provide a large number of cells. We investigated whether the allogeneic administration of FM-derived MSC (FM-MSC) attenuates myocardial injury and dysfunction in a rat myocarditis model. Experimental autoimmune myocarditis (EAM) was induced in male Lewis rats by injecting porcine cardiac myosin. Allogeneic FM-MSC obtained from major histocompatibility complex-mismatched ACI rats (5 × 10⁵ cells/animal) were injected intravenously into Lewis rats one week after myosin administration. At day 21, severe cardiac inflammation and deterioration of cardiac function were observed. The allogeneic administration of FM-MSC significantly attenuated inflammatory cell infiltration and monocyte chemoattractant protein 1 expression in the myocardium and improved cardiac function. In a T-lymphocyte proliferation assay, the proliferative response of splenic T lymphocytes was significantly lower in cells obtained from FM-MSC-treated EAM rats that reacted to myosin than in cells obtained from vehicle-treated rats with EAM. T-lymphocyte activation was significantly reduced by coculture with FM-MSC. The allogeneic administration of FM-MSC attenuated myocardial dysfunction and inflammation, and the host cell-mediated immune response was attenuated in a rat model of acute myocarditis. These results suggest that allogeneic administration of FM-MSC might provide a new therapeutic strategy for the treatment of acute myocarditis.
