چکیده

Several mechanisms are associated with brain dysfunction during sepsis; one of the most important are activation of microglia and astrocytes. Activation of glial cells induces changes in permeability of the blood-brain barrier, secretion of inflammatory cytokines, and these alterations could induce neuronal dysfunction. Furthermore, blood-borne leukocytes can also reach the brain and participate in inflammatory response. Mechanisms involved in sepsis-associated brain dysfunction were revised here, focusing in neuroinflammation and involvement of blood-borne leukocytes and glial cells in this process.

P101: Neuroinflammation and Cognitive Dysfunction as a Side Effect of Abdominal Surgery

One of the most common postoperative complications is Postoperative cognitive dysfunction (POCD), and it’s usually a geriatric’s disease. Although many studies have done, the exact molecular mechanisms of POCD is still largely unknown; nevertheless, neuroinflammation has been increasingly denoted as one of the core mechanisms for the pathogenesis of POCD. As a hypothesize, surgery-i...

SEQUESTRATION OF LEUKOCYTES BY THE ISOLATED PERFUSED RAT LUNG

The sequestration of rat leukocytes and bone marrow cells by the lung vasculature was studied using an isolated perfused rat lung preparation. The passage of latex particles of 7.6 µm in diameter and non-hematopoietic cells through the lung blood vessels was also studied. Leukocytes and bone marrow cells were reversibly sequestered from circulation, whereas, latex particles and non-hematop...

Does Chronic Administration of Sodium Valproate to Juvenile Rats Induce Movement Disorder and Cognitive Dysfunction during Adulthood?

Background: Children with seizure disorder are often treated with sodium valproate (SV) on long-term basis. SV acts mainly through gamma amino butyric acid pathways, reducing the excitatory neurotransmission and modifying the monoamine concentration. Altered monoamine concentration by SV is expected to cause movement disorder and cognitive dysfunction, considered reversible after the withdrawal...

Infusible Platelet Membrane versus Conventional Platelet Concentrate: Benefits and Disadvantages

Blood transfusion centers are under considerable pressure to produce platelet concentrates with a shelf life limit of 3 to 5 days. Many approaches have been investigated experimentally to produce new hemostatically active platelet products that are capable of long term storage. In this article infusible platelet membrane will be explained as a platelet substitute versus conventional liquid-stor...
