Microcirculatory disturbances in the gastric mucosa was investigated in rats after thermal injury using intravital video microscopy. Mucosal blood flow decreased significantly 5 hrs after thermal injury and increased neutrophil-endothelial cell interaction was observed at the same time. Zymosan stimulated-free radical production from peripheral blood was also increased and acute gastric mucosal lesion (AGML) appeared 5 hrs after thermal injury. These data suggest that neutrophil-endothelial cell interaction and increased free radical production induce AGML formation and that microcirculatory disturbance is one of the main reasons for organ failure after surgical insults. The role of inflammatory cytokines in hepatic microcirculatory disturbance was also studied in endotoxin-injected rats using IL-1 receptor antagonist (IL-1Ra) or TNF binding protein (TNFbp). Pretreatment with IL-1Ra or TNFbp significantly improved hepatic microcirculatory disturbance and reduced both the number of leukocytes adhered to the sinusoidal wall and the number of injured cells as well. These data suggest that inflammatory cytokines play a crucial role in microcirculatory disturbance after surgical insults by promoting neutrophil-endothelial cell interaction and systemic excessive inflammation.

D005753 Gastric Mucosa Lining of the STOMACH, consisting of an inner EPITHELIUM, a middle LAMINA PROPRIA, and an outer MUSCULARIS MUCOSAE. The surface cells produce MUCUS that protects the stomach from attack by digestive acid and enzymes. When the epithelium invaginates into the LAMINA PROPRIA at various region of the stomach (CARDIA; GASTRIC FUNDUS; and PYLORUS), different tubular gastric glands are formed. These glands consist of cells that secrete mucus, enzymes, HYDROCHLORIC ACID, or hormones.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D016207 Cytokines Non-antibody proteins secreted by inflammatory leukocytes and some non-leukocytic cells, that act as intercellular mediators. They differ from classical hormones in that they are produced by a number of tissue or cell types rather than by specialized glands. They generally act locally in a paracrine or autocrine rather than endocrine manner. Cytokine

D018746 Systemic Inflammatory Response Syndrome A systemic inflammatory response to a variety of clinical insults, characterized by two or more of the following conditions: (1) fever >38 degrees C or HYPOTHERMIA <36 degrees C; (2) TACHYCARDIA >90 beat/minute; (3) tachypnea >24 breaths/minute; (4) LEUKOCYTOSIS >12,000 cells/cubic mm or 10% immature forms. While usually related to infection, SIRS can also be associated with noninfectious insults such as TRAUMA; BURNS; or PANCREATITIS. If infection is involved, a patient with SIRS is said to have SEPSIS. Inflammatory Response Syndrome, Systemic,Sepsis Syndrome,Sepsis Syndromes,Syndrome, Sepsis,Syndromes, Sepsis
