phenylalanine/hemorrhage

Vasopressin and its analogs are used inthe treatment of bleeding esophageal varices. Since gastrointestinal reflux may have a deleterious effect on variceal hemorrhage, the effect of 2,3-phenylalanine-8-lysine-vasopressin upon the lower esophageal sphincter (LES) was studies by rapid pull-through

Studies indicate that simple hemorrhage induces profound suppression in splenic and peritoneal macrophage (Mphi) functions such as antigen presentation, reduced major histocompatibility complex class II antigen expression, as well as cytokine release. Since many of these macrophage functions require

The primary sequences of the three individual glycoprotein (GP) chains, GPIb alpha, GPIb beta, and GPIX, comprising the normal platelet GPIb/IX receptor for von Willebrand factor (vWF) have recently been determined, opening the possibility for characterization of disorders of this receptor at the

Hemorrhagic coagulopathy is involved in the morbidity and mortality of trauma patients. Nonetheless, many aspects of the mechanisms underlying this disorder are poorly understood. We have therefore investigated changes in fibrinogen metabolism and coagulation function after a moderate hemorrhagic

A new series of benzoxazinone analogs were designed, synthesized, and assayed to determine their effects on superoxide anion generation and neutrophil elastase (NE) release in formyl-L-methionyl-L-leucyl-L-phenylalanine (FMLP)-activated human neutrophils. Of these, compounds 6-10 showed a potent

We measured amino acid concentrations in plasma and skeletal muscle of three groups of patients with acute hemorrhagic pancreatitis: (a) patients without secondary organ lesions, (b) patients also suffering from kidney damage, and (c) patients in whom the pancreatitis was accompanied by sepsis and

Hemorrhagic coagulopathy is a significant complication after traumatic injury, and much of the underlying mechanism remains unclear. We investigated the changes in fibrinogen metabolism and coagulation after a moderate hemorrhage and resuscitation. Pigs of either sex (weight, 40.9+/-0.8 kg) were

Our previous report demonstrates that severe gastric mucosal damage is produced in lipopolysaccharide (LPS)-intoxicated rats. In the present study, we examined protective effects of several amino acids including taurine, phenylalanine and L-Arginine on gastric hemorrhagic erosions in acid-irrigated

BACKGROUND Changes of plasma albumin and fibrinogen after various insults have been described as acute phase responses. This study investigated the acute changes of hepatic synthesis of albumin and fibrinogen after hemorrhage and resuscitation with lactated Ringer's (LR) solution or normal saline

BACKGROUND After trauma and hemorrhagic shock (T/HS), a variety of inflammatory mediators enter the systemic circulation through mesenteric lymph ducts, leading to acute lung injury and multiple-organ dysfunction syndrome. Recent studies have demonstrated that post-HS mesenteric lymph (PHSML)

BACKGROUND Fibrinogen plays a central role in coagulation and falls to critical levels early after trauma. Administration of fibrinogen concentrate (FC) to improve hemostasis after severe bleeding seems beneficial, but it is unclear whether its use introduces excessive fibrinogen with a potential

Pressor amine therapy in circulatory shock has been generally unfavorable, presumably because these drugs produce unselective, intense vasoconstriction and curtail rather than improve true capillary inflow, distribution and outflow in the microcirculation. The present study compares the influence of

The pathophysiology underlying the high incidence of post-stroke infectious complications has not been fully understood. We measured the respiratory burst of neutrophils as an index of their bactericidal function in patients with haemorrhagic stroke, and we also measured the plasma concentrations of
