Luoyutong (LYT) capsule has been used to treat cerebrovascular diseases clinically in China and is now patented and approved by the State Food and Drug Administration. In this retrospective validation study we investigated the ability of LYT to protect against cerebral ischemia-reperfusion injury in rats. Cerebral ischemia-reperfusion injury was induced by middle cerebral artery occlusion followed by reperfusion. Capsule containing LYT (high dose and medium dose) as treatment group and Citicoline Sodium as positive control treatment group were administered daily to rats 30 min after reperfusion...

In recent years, citicoline has been the object of remarkable interest as a possible neuroprotectant. The aim of this study was to investigate if citicoline affected cell survival in primary retinal cultures and if it exerted neuroprotective activity in conditions modeling retinal neurodegeneration. Primary retinal cultures, obtained from rat embryos, were first treated with increasing concentrations of citicoline (up to 1000 µM) and analyzed in terms of apoptosis and caspase activation and characterized by immunocytochemistry to identify neuronal and glial cells...

UNLABELLED: HASH(0x44d57f8) BACKGROUND: Citicoline is one of the neuroprotective agents that have been used as a therapy in stroke patients. There is limited published data describing the mechanisms through which it acts. METHODS: We used in vitro angiogenesis assays: migration, proliferation, differentiation into tube-like structures in Matrigel™ and spheroid development assays in human brain microvessel endothelial cells (hCMEC/D3). Western blotting was performed on protein extraction from hCMEC/D3 stimulated with citicoline...

In order to assess the role of apoptosis in pathogenesis of primary open-angle glaucoma (POAG) apoptosis markers were studied in blood serum and tear fluid of patients with or suspected to have different stages glaucoma. To date the study of POAC pathogenesis goes along with search of possible ways of pharmacotherapy, neuroprotection is considered to be a promising option. Dynamics of sFas/Apo-1 and sFasL as the markers of Fas-mediated apoptosis was studied during treatment. We used nootropic citicoline as a neuroprotector...

UNLABELLED: Pneumococcal meningitis can lead to death or serious neurological sequelae as a result of the host inflammatory response. We investigated the association between host response protein expression and outcome in patients with pneumococcal meningitis. Cerebrospinal fluid (CSF) was obtained from 80 patients with pneumococcal meningitis (40 nonsurvivors and 40 survivors) and 10 normal controls. Candidate proteins were analyzed for an association with survival. Complement C3 levels were 5-fold lower in nonsurvivors than in survivors (P < 0...

Fetal alcohol syndrome (FAS) is caused by maternal alcohol consumption during pregnancy. The reason why specific embryonic tissues are sensitive toward ethanol is not understood. We found that in neural crest-derived cell (NCC) cultures from the first branchial arch of E10 mouse embryos, incubation with ethanol increases the number of apoptotic cells by fivefold. Apoptotic cells stain intensely for ceramide, suggesting that ceramide-induced apoptosis mediates ethanol damage to NCCs. Apoptosis is reduced by incubation with CDP-choline (citicoline), a precursor for the conversion of ceramide to sphingomyelin...

The purpose of this study was to investigate the effect of brain-derived neurotrophic factor (BDNF), neurotrophin-4 (NT-4), and citicoline on neuronal apoptosis and neurite regeneration in cultured rat retinas exposed to high glucose (HG). The retinas of six adult Sprague-Dawley rats were studied. After the rats were euthanized, the retinas were isolated and cultured in serum-free medium. One group of explants was cultured in normal glucose (NG) and another group in HG medium (HGM). BDNF, NT-4, or citicoline were added to the HGM...

BACKGROUND: Ischemic spinal cord injury is a chain of events caused by the reduction and/or cessation of spinal cord blood flow, which results in neuronal degeneration and loss. Ischemic postconditioning is defined as a series of intermittent interruptions of blood flow in the early phase of reperfusion and has been shown to reduce the infarct size in cerebral ischemia. Our study aimed to characterize the relationship between the neuronal injury-decreasing effects of citicoline and ischemic postconditioning, which were proven to be effective against the apoptotic process...

The effects of citicoline used either alone or in combination with hypothermia on the suppression of apoptotic processes after transient focal cerebral ischemia were investigated. Middle cerebral artery occlusion (MCAo) was performed for 2 hours on Sprague-Dawley (SD) rats using intraluminal thread insertion. The treatment groups were as follows: Group 1, sham-operated; Group 2, saline; Group 3, citicoline (400mg/kg intraperitoneal.); Group 4, hypothermia (34+/-1 degrees C); Group 5, citicoline+hypothermia...

To estimate protective potential of citicoline in a model of birth asphyxia, the drug was given to 7-day old rats subjected to permanent unilateral carotid artery occlusion and exposed for 65 min to a hypoxic gas mixture. Daily citicoline doses of 100 or 300 m/kg, or vehicle, were injected intraperitoneally for 7 consecutive days beginning immediately after the end of the ischemic-hypoxic insult, and brain damage was assessed by gross zorphology score and weight deficit two weeks after the insult. Caspase-3, alpha-fodrin, Bcl-2, and Hsp70 levels were assessed at 0, 1, and 24 h after the end of the hypoxic insult in another group of rat pups subjected to the same insult and given a single dose of 300 m/kg of citicoline or the vehicle...

Cytidine-5-diphosphocholine (CDP-choline, citicoline) is an endogenous nucleoside involved in generation of phospholipids, membrane formation and its repair. It demonstrates beneficial effects in certain central nervous system injury models, including cerebral ischaemia, neurodegenerative disorders and spinal cord injury. Defective neuronal and/or glial glutamate transport is claimed to contribute to progressive loss of motor neurons (MNs) in amyotrophic lateral sclerosis (ALS). Our previous ultrastructural studies, performed on an organotypic tissue culture model of chronic glutamate excitotoxicity, documented a subset of various modes of MN death including necrotic, apoptotic and autophagocytic cell injury...

Cytidine 5'-diphosphocholine, CDP-choline, or citicoline is an essential intermediate in the biosynthetic pathway of structural phospholipids in cell membranes, particularly phosphatidylcholine. Following administration by both the oral and parenteral routes, citicoline releases its two main components, cytidine and choline. Absorption by the oral route is virtually complete, and bioavailability by the oral route is therefore approximately the same as by the intravenous route. Once absorbed, citicoline is widely distributed throughout the body, crosses the blood-brain barrier and reaches the central nervous system (CNS), where it is incorporated into the membrane and microsomal phospholipid fraction...

Citicoline and lithium (Li(-)) have been shown to support retinal ganglion cell (RGC) survival and axon regeneration in vitro. Optic nerve crush (ONC) is a model of both brain axonal injury and certain aspects of the glaucomatous degeneration of RGC. We have used this model to quantify protection offered to RGC by these drugs and to determine whether their effects are mediated by enhanced expression of the antiapoptotic protein Bcl-2. Adult rats (6-12 per group) were subjected to ONC accompanied by a contralateral sham operation...

Citicoline is an essential endogenous intermediate in the biosynthesis of phosphatidylcholine, which acts as a therapeutic agent in models of central nervous system injury and neurodegenerative diseases. The present study investigated the effects of citicoline on extracellular-signal-regulated kinase 1/2 (ERK1/2) expression in the rat retina after kainic acid (KA) treatment. KA (6 nmol) was injected into the vitreous of the rat eyes. The animals were then injected intraperitoneally with citicoline (500 mg/kg) twice daily after the KA injection...

Cerebral ischemia triggers a multitude of pathophysiological and biochemical events that separately affect the evolution of focal ischemia and, therefore, stroke treatment should logically employ all known neuroprotective agents. We hypothesized that a treatment combining nimodipine and citicoline might have a potential neuroprotective effect. To assess this idea, Sprague-Dawley rats underwent transient bilateral common carotid artery ligation with simultaneous middle cerebral artery occlusion for 60 min. Four treatment groups were established...

Citicoline, or CDP-choline, is an essential endogenous intermediate in the biosynthesis of phosphatidylcholine that may act as a neuroprotector in several models of neurodegeneration. The present study analyses the effects of citicoline in the paradigm of staurosporine-induced cell death in human SH-SY5Y neuroblastoma cells. Citicoline reduces apoptosis induced by 100 nM staurosporine for 12 h in SH-SY5Y cells. This effect is higher with pre-treatment of 60 mM citicoline for 24 h after staurosporine challenge...

Citicoline has been demonstrated to be beneficial in several models of cerebral ischaemia. We tested the hypothesis that citicoline may provide apoptotic pathways following focal cerebral ischaemia. Focal cerebral ischaemia was produced by distal, permanent middle cerebral artery occlusion (MCAO) in Sprague-Dawley rats. The animals were randomised into four groups: (B+A) Citicoline 500 mg/kg IP 24 and 1 h before MCAO, and 23 h after MCAO; (A) citicoline 500 mg/kg IP, within 30 min after MCAO, and 23 h after MCAO; (C) vehicle IP; and (D) sham-operated...

Citicoline (exogenous CDP-choline) is a nontoxic and well-tolerated drug used in pharmacotherapy of brain insufficiency and some other neurological disorders, such as stroke, brain trauma, and Parkinson's disease. A few reports indicate that citicoline treatment may also be beneficial in glaucoma. Currently glaucoma is considered a neurodegenerative disease in which retinal ganglion cells (RGC) slowly die, likely in the apoptotic mechanism. Endogenous CDP-choline is a natural precursor of cellular synthesis of phospholipids, mainly phosphatydylcholine (PtdCho)...
