Vascular thrombotic disorders have emerged as a serious threat to our society. Platelet adhesion to fibrinogen, collagen and other platelet activators exposed over the atherosclerotic plaques can trigger platelet signaling events, activate platelets and lead to thrombotic events. Since anticoagulant and thrombolytic treatment strategies are usually associated with serious bleeding complications, preventing platelets adhesion may help to maintain platelets in an inactive state. In this study we tried to find out the effect of Silver nanoparticles, through their interaction with various platelet surface integrins on platelet adhesion on immobilized fibrinogen. Platelets, isolated from anti-coagulated human whole blood sample from healthy donors, were suspended in physiological buffer and each sample was divided into four tubes. In three of them 0.05, 0.5, and 5 μM concentrations of Silver nanoparticles were added, fourth tube served as control. Platelet adhesion on immobilized fibrinogen matrices and integrin mediated cell signaling events were studied in all the four samples. In the present study we show that nanosilver prevent platelet adhesion without conferring any lytic effect on them and effectively prevents integrin-mediated platelet responses in a concentration-dependent manner. 相似文献

This work was designated to monitor the coagulation abnormalities associated with the gradual progression of liver diseases. The study included fifty patients; forty were diagnosed with liver cirrhosis with different stages categorized according to the Childs-Pugh classification and another ten patients were diagnosed with hepatocellular carcinoma (HCC). Haemostatic variables including fibrinogen (FI), calcium (FIV), transglutaminase (FXIII), prothrombin time (PT) and platelet count were estimated in patients and compared with the baseline levels of healthy subjects (n = 10). The results demonstrated that the fibrinogen level was progressively decreased, whereas PT was progressively prolonged in Child A, Child B and Child C groups. The maximum deterioration was observed in HCC patients. Calcium significantly increased in mild (Child A) and moderate (Child B) but not in Child C cirrhosis and HCC patients. FXIII level did not show any significant changes in cirrhotic patients compared to healthy group. Some of the haemostatic variables we investigated were correlated with serum albumin and bilirubin but not with aminotransferases (ALT and AST). The results indicated that the haemostatic abnormalities in fibrinogen, calcium and PT (but not FXIII) were deteriorated in parallel with the gradual regression of the constitutional function of liver. 相似文献

The EGF-R, also known as HER-1 or erbB-1 (EGF-R/HER-1/erbB-1), is a member of the human epithelial receptor tyrosine kinase
family. sEGF-R is considered to play a role in cardiac (patho)physiology. We aimed to investigate whether soluble EGF-R is
increased in congestive heart failure (CHF) patients and if related to disease severity. Soluble EGF-R, vitamin D, parathyroid
hormone (PTH) was studied, and being evaluated in relation to Ca2+, lipids, hsCRP, fibrinogen, serotonin, norepinepherine (NE). The study compared non-smoker, non-obese male CHF patients (n = 50) with age and gender-matched essential hypertension (HTN) patients (n = 20). Moreover, comparison with healthy control volunteers (n = 20) were employed. EGF-R/HER-1/erbB-1 was higher (P = 0.013) in 50 CHF male patients mean 12 ± 0.7 fmol/ml, than in 20 HTN, 9.25 ± 0.6 fmol/ml or in 20 controls, 6.25 ± 1 fmol/ml.
Serum EGF-R levels correlated positively with hsCRP and NE, and were highest among CVD patients (n = 70) as well as negatively with vitamin D and HDL-C. EGF-R/HER-1/erbB-1 levels are increased in HTN and more in CHF patients.
This study confirms a strong association between catecholamines as well as EGF-R/HER-1/erbB-1 levels with PTH and low vitamin
D levels, being related to hyperlipidemia and inflammation (hsCRP and fibrinogen) in CVD. Moreover, contributing to the complex
process of the inflammatory component of atherosclerosis in hypertensive patients that leads eventually to CHF. 相似文献

Coronary artery disease (CAD) is a global epidemic currently. This study was planned to evaluate markers of inflammation and hemostasis and their possible association, if any, in patients with CAD. The study was carried out in 60 patients with acute myocardial infarction (AMI) and 60 age and gender matched controls. The following parameters were assayed in all study subjects-inflammatory-interleukin (IL)-10, high sensitivity C-reactive protein (hs-CRP), tumor necrosis factor (TNF)-α, fibrinogen; hemostatic-fibrinogen, fibrin D-dimer and a novel risk factor—homocysteine. Inflammatory markers (hs-CRP, TNF-α and IL-10), fibrinogen, fibrin D-dimer and homocysteine levels were significantly higher in the patients with AMI, as compared with controls. A positive correlation was observed between D-dimer and the inflammatory markers—hs-CRP and TNF-α. Upon multivariate analysis, TNF-α emerged as the best determinant of CAD in our study. Our results indicate that there is a possible interplay of inflammation and hemostasis in CAD, underlining their synergistic role in the pathogenesis of CAD. 相似文献

Growth retardation is one of the significant changes in chronic kidney disease (CKD) and is associated with increased morbidity and mortality. Disturbances in growth hormone (GH) are held responsible for several complications in CKD. GH is a protein based peptide hormone which directly or indirectly regulates renal functions to ensure homeostasis. We investigated the effects of growth hormone on plasminogen activators (PA) in rat kidney, PA and plasminogen activator inhibitor (PAI), glucose and fibrinogen in plasma and serum lipid profile. Rats were injected daily with 250 mU GH kg-1 body weight subcutaneously for one week. Growth hormone treatment increased PA activity significantly in rat kidneys as compared to controls. No changes were seen in PA, PAI and fibrinogen levels in the plasma of two groups of rats. There was significant decrease in plasma glucose, total cholesterol and LDL-cholesterol levels in serum of treated group resulting in the decrease of HDL/LDL and total cholesterol/cholesterol ratios. However, triglycerides and VLDL showed significant higher activity in the serum of treated group as compared to controls. Our data suggests that GH administration might improve renal function by increasing PA activity in kidney as well as by reducing the cholesterol content in blood. GH may be effective in improving growth failure as it helps to maintain the normal homeostatic balance. 相似文献
