Type 1 plasminogen activator inhibitor (PAI-1), the primary inhibitor of tissue-type plasminogen activator (t-PA), circulates as a complex with the abundant plasma glycoprotein, vitronectin. This interaction stabilizes the inhibitor in its active conformation In this report, the effects of vitronectin on the interactions of PAI-1 with fibrin clots were studied. Confocal microscopic imaging of p...

Objective(s): Sepsis can result in severe organ injury by provoking inflammatory cascades and oxidative stress. Several studies are currently underway to find a drug with anti-inflammatory effects to prevent mortality and morbidity during sepsis. The present study was undertaken to assess the effects of metformin on oxidative stress and antioxidant status in sepsis induced by the Cecal Ligation...

a 20-year-old woman was admitted to a gynecology hospital in her 6th month of pregnancy for high blood pressure and tonic-clonic seizure. primary diagnosis was eclampsia, and for that reason she underwent cesarean section. she also had headache on frontal and parietal areas without nausea or vomiting. there was not a focal neurological sign. rheumatology consultation was requested. systemic lup...

purpose: to compare the effect of tissue plasminogen activator (tpa) and aspirin in patients with central retinal vein occlusion. methods: a prospective interventional study was conducted on patients with central retinal vein occlusion of less than 28 days' duration. patients in the tpa group received 100 μg intravitreal tissue plasminogen activator and the patients who declined intravitre...

Fibrinolytic activity of the retinae in control and diabetic rats was assayed quantitatively in twenty male rats made diabetic by giving a single injection of streptozotocin. All these rats were killed at either 3 months or 12 months. Ten saline-injected rats and five rats treated with 3-0-methylglucose and streptozotocin served as controls. As the plasminogen activator activity in diabetic rat...

Recombinant tissue plasminogen activator may be effective in preventing cerebral vasospasm after subarachnoid hemorrhage by resolving subarachnoid clots. We previously demonstrated that blood placed on the adventitial surface of cerebral arteries enhances intimal platelet accumulation, positively correlating with endothelial damage and other pathologic changes in vessel walls. In this study, we...

The functional maturity of T and B lymphocyte populations from human newborns was evaluated using a reverse hemolytic plaque assay to detect immunoglobulin-secreting cells generated in in vitro cultures stimulated with pokeweed mitogen (PWM), a T cell-dependent polyclonal activator, and the Epstein-Barr virus (EBV), a T cell-independent B cell activator. Cord blood lymphocytes failed to produce...

Aim: The aim of this study is to investigate some immuno-haematological characteristics of Nigerian sickle cell disease (SCD) patients in asymptomatic steady state. Material and Methods: Thirty asymptomatic SCD patients and 30 apparently healthy ageand sex-matched non-sickle cell disease individuals were investigated. The packed cell volume, white blood cells and differentials, and platelet cou...

We describe positive interference with the ion-selective electrode determination of lithium (Lytening 2Z analyzer; Dade) when blood is collected in a 10-mL plain red-top plastic Vacutainer Plus Tube (Becton Dickinson) containing a silica clot activator and silicone surfactant (prod. no. 36-7820). We evaluated both the original tube (blue-labeled) and a new tube formulated to contain less silico...
