Copper,zinc-superoxide dismutase (SOD1) was shown to be highly protective against ischemia/reperfusion injury in the brain. We have recently reported that SOD1 prevents the release of mitochondrial cytochrome c and subsequent apoptosis after ischemia/reperfusion in mice. To investigate its dose

OBJECTIVE Aim of this study is to protect donor liver against ischemia-reperfusion injury by abating Cytochrome C induced apoptosome on rat model. METHODS A total of 25 clean SD inbred male rats were used in this research. The rats in ischemia-reperfusion injury group (I/R group, n=5) were under

Vasogenic edema after oxidative injury has been accompanied by intracellular accumulation of serum proteins and nuclear damage. This study sought to determine whether serum protein accumulation, along with other markers of brain injury, was present after exposure to intracerebral hemolysate, an

Activities of lung NADPH-cytochrome C-reductase and of cytochrome P-450 peroxidase during the protection of rat from hyperoxic injury by polyriboinosinic acid-polyribocytidilic acid.

Rats exposed to normobaric oxygen received a single i.p. injection of 2.5 mg/kg of poly I: poly C at various times (-120 to +36 h) before and after the beginning of oxygen exposure. Hyperoxic lung damage and modifications in cytochrome P-450 system components were evaluated. Our results confirmed

Autosomal recessive mutations in the RARS2 gene encoding the mitochondrial arginyl-transfer RNA synthetase cause infantile-onset myoencephalopathy pontocerebellar hypoplasia type 6 (PCH6). We describe 2 sisters with novel compound heterozygous RARS2 mutations who presented perinatally with

1. Nilvadipine (FK 235, FR 34235) suppressed ischemia (20 min)-reflow (20 min)-induced paw edema of mice (ED30:0.4 mg/kg i.v. and 2 mg/kg p.o.). Other calcium entry blockers of dihydropyridine-type also suppressed the edema, but 30-fold higher doses were required. 2. Oral dosing of nilvadipine

High levels of homocysteine (Hcy) known as hyperhomocysteinemia (HHcy), contribute to autophagy and ischemia/reperfusion injury (I/R). Previous studies have shown that I/R injury and HHcy cause increased cerebrovascular permeability; however, the associated mechanism remains obscure. Interestingly,

An ultrastructural study of alveolar permeability to cytochrome C in the rabbit lung: effect of exposure to 100% oxygen at one atmosphere.

Rabbits were exposed to 100% oxygen or to air at one atmosphere. No alterations were observed in the lung of rabbits breathing air for up to 66 hours or 100% oxygen for 24 hours; after 48 hours, inflammatory cells, chiefly neutrophils, were located in the interstitium of the lung. By 66 hours of

Ketone bodies have been shown to be favorable alternative metabolic substrates and are protective under neuropathologies. At the same time, cytochrome c release has been reported following traumatic brain injury (TBI) and precipitates apoptosis via the mitochondrial pathway. The present study

Opposite effect of superoxide dismutase, L-arginine analogues, methylene blue and desferal: suppression of histamine-induced and stimulation of serotonin-induced paw edema in mice.

Endogenous nitric oxide (NO, endothelium-derived relaxing factor) was stimulatory for histamine- and suppressive for serotonin-induced paw edema of mice. This action was mediated by guanosine 3',5'-cyclic monophosphate production. Local injection of superoxide dismutase (SOD), catalase,

The therapeutic efficacy of a regimen consisting of intravenous injection of Cardiocrome, containing cytochrome c, flavin mononucleotide and thiamine diphosphate for mitochondrial encephalomyopathy (MEM) was examined. This combined therapy was applied to nine patients with MEM, including four with

OBJECTIVE To explore the effects of hyperbaric oxygen (HBO) treatment on the neuronal apoptosis at an earlier stage and the expressions of Cytochrome C (Cyt C), Bcl-2 (B-cell lymphoma-2 family) and Bax (Bcl-2 associated X protein) in rat brain tissues after traumatic brain injury

Carbon monoxide is the leading cause of fatal poisoning in many countries. At least two mechanisms of CO toxicity are currently recognized: carboxyhemoglobin formation and CO binding to haeme proteins such as mitochondrial cytochrome C oxidase and myoglobin. However, a growing body of evidence also

Carnosine Attenuates Brain Oxidative Stress and Apoptosis After Intracerebral Hemorrhage in Rats.

Carnosine, an endogenous dipeptide (β-alanyl-L-histidine), exerts multiple neuroprotective properties, but its role in intracerebral hemorrhage (ICH) remains unclear. This study investigates the effect of Carnosine on brain injury using the rat ICH model, which is established by type IV collagenase
