cytidine/脳卒中

Brain phosphatidylcholine (PC) levels are regulated by a balance between synthesis and hydrolysis. Pro-inflammatory cytokines such as tumor necrosis factor-alpha (TNF-alpha) and interleukin-1 (IL-1alpha/beta) activate phospholipase A(2) (PLA(2)) and PC-phospholipase C (PC-PLC) to hydrolyze PC. PC

Citicoline (CDP-choline; cytidine 5'-diphosphocholine), a form of the essential nutrient choline, shows promise of clinical efficacy in elderly patients with cognitive deficits, inefficient memory, and early-stage Alzheimer's disease. Citicoline has also been investigated as a therapy in stroke

Citicoline (CDP-choline; cytidine 5'-diphosphocholine) is an important intermediate in the biosynthesis of cell membrane phospholipids. Citicoline serves as a choline donor in the biosynthetic pathways of acetylcholine and neuronal membrane phospholipids, mainly phosphatidylcholine. The ability of

OBJECTIVE We sought to evaluate the effects of the combination of cytidine-5'-diphosphocholine (citicoline) and thrombolysis on infarct size, clinical outcome, and mortality in a rat embolic stroke model. METHODS Eighty-three Sprague-Dawley rats were embolized in the carotid territory with a single

OBJECTIVE Citicoline (cytidine-5'-diphosphocholine; CDP-choline) may reduce central nervous system ischemic injury by stabilizing cell membranes and reducing free radical generation. A previous dose-comparison trial in patients with acute stroke found that 500 mg of citicoline appeared to improve

The basal and GH-releasing hormone-stimulated secretion of GH declines in the elderly. We tested the ability of cytidine 5'-diphosphocholine, a drug used in the treatment of stroke and Parkinson's disease, to alter GH secretion in 11 healthy elderly volunteers, aged 69-84. Each subject received an

Stroke is a medical emergency with a mortality rate higher than most forms of cancer. It is the second leading cause of death in developed countries and the most common cause of serious, long-term disability in adults.Primary intracerebral hemorrhage (ICH) is a major clinical problem that accounts

Use of thrombolysis in acute ischaemic stroke may be limited by a narrow benefit/risk ratio. Pharmacological inhibition of the ischaemic cascade may constitute an effective and safer approach to stroke treatment. This study compared the effects of high doses of cytidine diphosphate-choline

BACKGROUND Cytidine diphosphate choline (citicoline) has been previously shown to have efficacy in reducing the functional impairments associated with acute stroke. Citicoline is thought to have neuroprotective benefits and has been used for the treatment of chronic cerebrovascular disorders, though

Beneficial effects of cytidine (5') diphosphocholine (CDP-choline) administration on several diseases including brain aging, ischemia and stroke are based on an increase in membrane phospholipid turnover. We have studied the possible involvement of CTP:phosphocholine cytidylyltransferase (CT) in

Cytidine-5'-diphosphocholine (CDP-choline, Citicoline, Somazina) is in clinical use (intravenous administration) for stroke treatment in Europe and Japan, while USA phase III stroke clinical trials (oral administration) were disappointing. Others showed that CDP-choline liposomes significantly

Nifedipine and nimodipine, dihydropyridine calcium channel blockers, are commonly used as antihypertensive and antianginal agents in patients at risk for stroke. At least one stroke trial suggests that patients receiving calcium channel blockers at the time of an acute stroke have worse outcomes

Citicoline (cytidine-5'-diphosphocholine or CDP-choline) is a precursor essential for the synthesis of phosphatidylcholine, one of the cell membrane components that is degraded during cerebral ischemia to free fatty acids and free radicals. Animal studies suggest that citicoline may protect cell

Citicoline (cytidine 5'-diphosphocholine) is an important precursor for the synthesis of neuronal plasma membrane phospholipids, mainly phosphatidylcholine. The administration of citicoline serves as a choline donor for the synthesis of acetylcholine. Citicoline has been shown to reduce the neuronal

Cytidine and choline, present in cytidine 5'-diphosphate choline (CDP-choline), are major precursors of the phosphatidylcholine found in cell membranes and important regulatory elements in phosphatide biosynthesis. Administration of CDP-choline to rats increases blood and brain cytidine and choline
