BACKGROUND
Hemorrhagic shock causes a rapid depletion of adenosine triphosphate (ATP) and an increase of the terminal metabolite xanthine. Free radicals generated from xanthine oxidase play a major role in cell injury. Programmed cell death, apoptosis, is a major pathway causing reperfusion injury.
BACKGROUND
Glutamine supplementation of total parenteral nutrition (TPN) in stressed patients has been advocated. To determine whether glutamine supplementation affects the host response to conditions of stress, animals were given TPN with or without glutamine for 7 days. They were then subjected to
Cerebrospinal fluid concentration of glutamine was measured in 43 premature and mature babies suffering from intracranial hemorrhage. Compared with a control group of 38 infants we found elevated levels in all infants with intraparenchymal and subarachnoid hemorrhages. Two out of ten children with
BACKGROUND
This observational microdialysis (MD) study of 33 subarachnoid hemorrhage patients explores brain interstitial levels of glutamine, glutamate, lactate and pyruvate, and their relationship to clinical status and clinical course at the neurointensive care unit.
METHODS
The focus was on
The profound hypotension caused by acute hemorrhage is thought to involve opioid peptide neurons. In this study, we tested whether glycyl-L-glutamine [Gly-Gln; beta-endorphin-(30-31)], a nonopioid peptide derived from beta-endorphin processing, prevents the cardiovascular depression induced by
Crimean-Congo hemorrhagic fever (CCHF) is a viral disease. There is not enough knowledge about plasma amino acid levels in CCHF. Therefore, we investigated of plasma amino acids levels in patients with CCHF and the association between the levels of these amino acids and disease severity. The plasma
OBJECTIVE
Glutamine (Gln) is now considered as conditionally essential amino acid with many biological activities. This study aimed to investigate whether it has protective effects on the intestinal mucosal barrier in young rabbits under hemorrhagic shock.
METHODS
Eighteen young rabbits aged 26 +/-
OBJECTIVE
To find out whether supplementation of an enteral diet with glutamine would reduce translocation of bacteria to mesenteric lymph nodes or blood after major haemorrhage in rats.
METHODS
Open randomised study.
METHODS
University departments of surgery and microbiology, Sweden.

Intestinal blood flow has been shown to be impaired after resuscitated hemorrhagic shock. Enteral feeding has been proposed as an adjunct for preserving mucosal integrity and decreasing translocation-related morbidities during stress. The purpose of this study was to determine if an ileal mucosal
Glutamine is an essential substrate for gut mucosal structure, but the role for gut immune function is not fully known. To determine the effect on gut cytokine release in relation to bacterial translocation and gut morphology, a nonlethal hemorrhagic shock (30 min, 30 mmHg) was performed in male
OBJECTIVE
The aim of this study was to explore the relationship between hemodynamics (intracranial and systemic) and brain tissue energy metabolism, and between hemodynamics and glutamate (Glt)-glutamine (Gln) cycle activity.
METHODS
Brain interstitial levels of lactate, pyruvate, Glt, and Gln were
Hemorrhagic shock (HS) is an oxidative stress that causes intestinal tissue injury. Heme oxygenase 1 (HO-1) is induced by oxidative stress and is thought to play an important role in the protection of tissues from oxidative injury. We previously reported the ileum to be the most susceptible to
BACKGROUND
Inflammatory factors play an important role in the production of cellular damage after shock and reperfusion. Glutamine has been used to modulate the inflammatory response. Alanine-glutamine dipeptide (AGD) is a glutamine source. The hypothesis of the present study is that AGD given
Bacterial translocation across the gut wall may be associated with insult to the latter. In this situation, intestinal flora can enter the blood stream and lymph nodes and be transported to other organs. Glutamine is a nonessential amino acid not presently included in total parenteral nutrition
Cyclophosphamide (CP) is widely used in the treatment of cancer and non-malignant disease states such as rheumatoid arthritis. Hemorrhagic cystitis is a major dose-limiting side effect of CP. The incidence of this side effect is related to the dosage and can be as high as 75%. Elimination of the
