BACKGROUND
Heme oxygenase 1 (HO-1) has been shown to attenuate neuronal injury. Therefore, the authors examined whether HO-1 would reduce the brain damage caused by cardiac arrest.
METHODS
Rats anesthetized with halothane were subjected to 8 min of cardiac arrest by asphyxia without any pretreatment
Brain edema formation associated with trauma-induced intracerebral hemorrhage (ICH) is a clinical complication with high mortality. Studies have shown that heme oxygenase-1 (HO-1) plays an important role in ICH-induced brain edema. In order to understand the role of HO-1 in the protective effect of
Heme oxygenase-1 (HO-1), which catalyzes the degradation of free heme to biliverdin, carbon monoxide (CO), and free iron (Fe(2+)), is up-regulated by several cellular stress and cell injuries, including inflammation, ischemia and hypoxia. In this study, we examined whether fusion of HO-1 with PEP-1,
The lung and kidney are two organs that are easily affected by hemorrhagic shock (HS). We investigated roles of biliary tract external drainage (BTED) in inflammation and edema of the lung and kidney in HS and its relationship with the heme oxygenase-1 (HO-1) pathway. Rat models of HS were induced
Intracranial bleeding is a common and serious consequence of traumatic brain injury (TBI). In the present study, we investigated cerebral hematoma occurrence, brain edema formation, blood-brain barrier (BBB) disruption, and heme oxygenase-1 (HO-1) expression after TBI. Moderate severity (1.8-2.2
Cardamonin is a chalcone isolated from Alpinia katsumadai. This study is aimed to evaluate treatment of cardamonin decreased the paw edema at the 5th hour after λ-carrageenan (Carr) administration and increased the activities of catalase (CAT) and superoxide dismutase (SOD) in the anti-inflammatory
Dihydrofisetin is a flavanonol derived from some edible wild herbs and traditional Chinese medicines. It has been found to possess many biological activities. However, the anti-inflammatory potential of Dihydrofisetin remains uncharacterized. The aim of the present study was to investigate the
The ear edema of the mouse induced by local application of arachidonic acid is suitable for in vivo differentiation of lipoxygenase (LOX) and cyclooxygenase (COX) inhibitors. LOX blockers inhibit initially and plateau-like during the first hour of the course of the edema, while COX-blockers do so
The possibility that the upregulation of hemeoxygenase (HO) enzyme responsible for carbon monoxide (CO) formation in the spinal cord following trauma is involved in edema formation and cell damage was examined in a rat model. A focal trauma to the rat spinal cord by making an incision into the right
Although studies have demonstrated that heme oxygenase-1 (HO-1) prevents leukocyte infiltration and organ damage following LPS challenge, the mechanisms involved in this protection are incompletely understood. Macrophage migration inhibitory factor (MIF) is thought to play a pivotal role in
Gut mucosal injury observed during ischemia-reperfusion is believed to trigger a systemic inflammatory response leading to multiple organ failure. It should be interesting to demonstrate this relationship between gut and multiple organ failure in a sepsis model. Intestinal preconditioning (PC) can
Heme oxygenase-1 (HO-1), a kind of stress protein, is critical for the protection against ischemic stroke and cerebrovascular endothelium damage. However, the effects of HO-1 on trauma-induced brain injury are still unknown. Hence, we attempted to use a cold injury-induced brain trauma (CIBT) model
Influence of a new antioxidant compound H-290/51 on carbon monoxide (CO) production following spinal cord injury was examined using immunohistochemistry of the constitutive isoform of heme oxygenase-2 (HO-2) in a rat model. Subjection of rats to 5 h spinal cord injury by making an incision into the
Global hypoxia preconditioning provides neuroprotection against a subsequent, normally damaging challenge. While the mechanistic pathways are unknown, changes in the expression of stress-related proteins are implicated. Hypoxia preconditioning attenuates the brain edema and neuropathology associated
Influence of a new anti-oxidant compound H-290/51 on expression of nitric oxide synthase (NOS) and heme oxygenase (HO) enzymes responsible for nitric oxide (NO) and carbon monoxide (CO) production, respectively was examined in the CNS following heat stress in relation to cell injury. Exposure of
