Little is known about phagocytosis-associated oxidative metabolism in mononuclear phagocytes from the human neonate. We investigated this phenomenon in monocytes from the cord blood of term newborn infants by measuring generation of superoxide anion (O2-) and hydroxyl radical (X OH) after stimulation with opsonized zymosan or phorbol myristate acetate. Production of these microbicidal oxygen me...

objective: receptor activator of nuclear factor-kappa b ligand (rankl) appears to be an osteoclast-activating factor, bearing an important role in the pathogenesis of multiple myeloma. some studies demonstrated that u-266 myeloma cell line and primary myeloma cells expressed rank and rankl. it had been reported that the expression of myeloid and monocytoid markers was increased by co-culturing ...

We examined the diurnal pattern in Plasminogen Activator Inhibitor-type 1 (PAI-1) activity and Plasminogen activator (t-PA) in relation to the 4G/5G-polymorphism in the promoter of the PAI-1 gene. The analyses were performed in the Arnhem Elderly Study, a population-based study of 598 elderly. A single blood sample was drawn and the time of blood sampling was recorded (between 8 a.m. and 5.30 p...

We studied thrombolysis in an animal model of embolic stroke to determine the safety of tissue plasminogen activator and streptokinase. We occluded the middle cerebral arteries of 137 rabbits with radiolabeled blood clots and administered tissue plasminogen activator (n=49), streptokinase («=40), or saline (n=48) at various times after embolization. We assessed the rate of thrombolysis and cere...

Stem cells have been successfully used for the treatment of critical limb ischemia (CLI). We conducted a clinical trial to determine the feasibility of using autologous adipose-derived mesenchymal stromal cells (AdMSCs) for the treatment of CLI. Unexpectedly, two diabetic patients developed peripheral microthrombosis. This adverse effect, which contrasts with the reported antithrombotic propert...

INTRODUCTION The aim of this paper was to describe the use of r-TPA for fibrin clot dissolution following endophthalmitis. CLINICAL PICTURE A 74-year-old man presented with painful loss of vision following routine uncomplicated cataract surgery. TREATMENT He underwent standard treatment for postoperative endophthalmitis but despite this, developed a dense fibrin clot. He underwent further i...

In an attempt to investigate the effect of tissue plasminogen activator in the resolution of intracerebral haematoma an experimental model of intracerebral haematoma was designed in the cat. A total of 24 adult cats were studied. Intracerebral hematomas were provoked by stereotaxically injecting 0.2 ml of dotted human blood into the left frontal lobe. Control animals received 0.2 ml of normal s...
