OBJECTIVE
Complement activation probably plays a pathogenic role in multiple organ failure in shock. This study evaluates the effects of C1-esterase-inhibitor treatment on leukocyte-endothelial interaction in the mesenteric microcirculation in hemorrhagic shock.
METHODS
Rats underwent median
BACKGROUND
Aspirin, with its analgesic, anti-inflammatory, antipyretic, and anti-platelet actions, is one of the most frequently used drugs. Although its use as prophylaxis against thromboembolism is well established, an optimal dose, conferring maximal anti-platelet action without increased risk of
Prior studies have shown that hemorrhage (Hem) can serve as a priming stimulus for acute lung injury (ALI) triggered by subsequent septic challenge (cecal ligation and puncture, CLP). Furthermore, we have reported that in vivo antibody neutralization of the chemokines, macrophage inflammatory
A heritable elevation in alpha 2-macroglobulin (alpha 2M) was identified in a 9-year-old girl with a severe bleeding tendency and activated partial thromboplastin time (APTT) prolonged to 49.1 sec (normal 27-38) as well as recalcification time prolonged to 438 sec (less than 180). The addition of
BACKGROUND
Hemorrhagic shock is known to alter significantly the pharmacokinetics of fentanyl, an opioid that requires delivery to the liver for metabolism. The authors hypothesized that the pharmacokinetics and pharmacodynamics of remifentanil, an esterase metabolized opioid that does not require
Hereditary haemorrhagic telangiectasia is characterized by arterio-venous malformations (AVM). It frequently involves the liver without clinical symptoms, but may lead to biliary ischaemia, portal hypertension, or fatal high-output heart failure. The indication of liver transplantation is
Activation of the complement system has been associated with tissue injury after hemorrhage and resuscitation in animals. We investigated whether administration of recombinant human C1-esterase inhibitor (rhC1-INH), a regulator of complement and contact activation systems, reduces tissue damage and
The present studies were done to evaluate the therapeutic potential of C1-esterase inhibitor in three different models of acute pancreatitis: (1) Edematous pancreatitis with acinar cell necrosis was induced by 7-h ip injections of 50 micrograms/kg cerulein in mice; (2) Hemorrhagic pancreatitis was
Antistreptococcal esterase (an antibody to extracellular esterase produced by Group A streptococci: ASE) was evaluated according to Hayano's method by using an assay kit on sera of children from two schools, one (F-school) in a non-epidemic state and the other (I-school) in an epidemic state of
OBJECTIVE
[corrected] There is no treatment proven to be of definitive benefit for ischemic stroke. Arginine esterase, a natural product from a snake venom, has been shown to reduce the serum fibrinogen level in human beings and may be useful in the treatment of ischemic stroke. In the present
Large-volume paracentesis (LVP) consists of the removal of more than four liters of ascitic fluid. This procedure can cause complications such as hemorrhage, infection, bowel perforation, circulatory failure, or ascitic fluid leakage. The main presentation of paracentesis-induced hemorrhage is
Bothrops insularis snake venom was fractionated by gel filtration on Sephadex G-150 followed by ion-exchange chromatography on SP-Sephadex C-25. Two active fractions were purified to homogeneity: (1) SIII-SpI, approximate mol. wt 32,000 and N-terminal amino acid residue Val. This fraction showed
Mean blood pressure and heart rate have been registered in the experiments on male Wistar rats. Kallikrein-kinin system (KKS) components have been evaluated in blood plasma: plasma kallikreinogen, kallikrein-inhibiting capacity, spontaneous esterase activity. The parameters were determined before
