Stroke

A stroke is a medical condition in which poor blood flow to the brain results in cell death. There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. They result in part of the brain not functioning properly. Signs and symptoms of a stroke may include an inability to move or feel on one side of the body, problems understanding or speaking, dizziness, or loss of vision to one side. Signs and symptoms often appear soon after the stroke has occurred. If symptoms last less than one or two hours it is known as a transient ischemic attack (TIA) or mini-stroke. A hemorrhagic stroke may also be associated with a severe headache. The symptoms of a stroke can be permanent. Long-term complications may include pneumonia or loss of bladder control.

The main risk factor for stroke is high blood pressure. Other risk factors include tobacco smoking, obesity, high blood cholesterol, diabetes mellitus, a previous TIA, and atrial fibrillation. An ischemic stroke is typically caused by blockage of a blood vessel, though there are also less common causes. A hemorrhagic stroke is caused by either bleeding directly into the brain or into the space between the brain's membranes. Bleeding may occur due to a ruptured brain aneurysm. Diagnosis is typically based on a physical exam and supported by medical imaging such as a CT scan or MRI scan. A CT scan can rule out bleeding, but may not necessarily rule out ischemia, which early on typically does not show up on a CT scan. Other tests such as an electrocardiogram (ECG) and blood tests are done to determine risk factors and rule out other possible causes. Low blood sugar may cause similar symptoms.

Prevention includes decreasing risk factors, as well as possibly aspirin, statins, surgery to open up the arteries to the brain in those with problematic narrowing, and warfarin in those with atrial fibrillation. A stroke or TIA often requires emergency care. An ischemic stroke, if detected within three to four and half hours, may be treatable with a medication that can break down the clot. Aspirin should be used. Some hemorrhagic strokes benefit from surgery. Treatment to try to recover lost function is called stroke rehabilitation and ideally takes place in a stroke unit; however, these are not available in much of the world.

In 2013 approximately 6.9 million people had an ischemic stroke and 3.4 million people had a hemorrhagic stroke. In 2015 there were about 42.4 million people who had previously had a stroke and were still alive. Between 1990 and 2010 the number of strokes which occurred each year decreased by approximately 10% in the developed world and increased by 10% in the developing world. In 2015, stroke was the second most frequent cause of death after coronary artery disease, accounting for 6.3 million deaths (11% of the total). About 3.0 million deaths resulted from ischemic stroke while 3.3 million deaths resulted from hemorrhagic stroke. About half of people who have had a stroke live less than one year. Overall, two thirds of strokes occurred in those over 65 years old.

    Don't buy the cheapest vitamins (they probably won't do much good) image When it comes to buying vitamins, don't go for the cheapest: they probably won't do you much good, new research has found.

    The most popular—and cheapest—brands of vitamins and minerals don't help prevent any of the major diseases, such as cardiovascular disease, heart attack, stroke or premature death.

    Popular multivitamins, and vitamin D, calcium and vitamin C supplements didn't have any protective effects, although they didn't do any harm either, say researchers at the University of Toronto, who analysed previously-published papers.

    Abstract:

    BACKGROUND AND AIMS:The Mediterranean diet, which is palatable and easily achievable, has been associated with lower all-cause and cardiovascular disease (CVD) incidence and mortality. Data on heart failure (HF) and stroke types are lacking. The aim was to examine a Mediterranean diet in relation to incidence of myocardial infarction (MI), HF and stroke types in a Swedish prospective cohort.

    METHODS:In a population-based cohort of 32,921 women, diet was assessed through a self-administered questionnaire. The modified Mediterranean diet (mMED) score was created based on high consumption of vegetables, fruits, legumes, nuts, whole grains, fermented dairy products, fish and monounsaturated fat, moderate intakes of alcohol and low consumption of red meat, on a 0-8 scale. Relative risks (RR) with 95% confidence intervals (CI), adjusted for potential confounders, were estimated by Cox proportional hazards regression models.

    RESULTS:During 10 y of follow-up (1998-2008), 1109 MIs, 1648 HFs, 1270 ischemic strokes and 262 total hemorrhagic strokes were ascertained. A high adherence to the mMED score (6-8), compared to low, was associated with a lower risk of MI (RR: 0.74, 95% CI: 0.61-0.90, p = 0.003), HF (RR: 0.79, 95% CI: 0.68-0.93, p = 0.004) and ischemic stroke (RR: 0.78, 95% CI: 0.65-0.93, p = 0.007), but not hemorrhagic stroke (RR: 0.88, 95% CI: 0.61-1.29, p = 0.53).

    CONCLUSIONS:Better adherence to a Mediterranean diet was associated with lower risk of MI, HF and ischemic stroke. The Mediterranean diet is most likely to be beneficial in primary prevention of all major types of atherosclerosis-related CVD.

    Abstract:

    Recent neuroimaging studies have demonstrated that stimulation of acupuncture at motor-implicated acupoints modulates activities of brain areas relevant to the processing of motor functions. This study aims to investigate acupuncture-induced changes in effective connectivity among motor areas in hemiparetic stroke patients by using the multivariate Granger causal analysis. A total of 9 stable recovery stroke patients and 8 healthy controls were recruited and underwent three runs of fMRI scan: passive finger movements and resting state before and after manual acupuncture stimuli. Stroke patients showed significantly attenuated effective connectivity between cortical and subcortical areas during passive motor task, which indicates inefficient information transmissions between cortical and subcortical motor-related regions. Acupuncture at motor-implicated acupoints showed specific modulations of motor-related network in stroke patients relative to healthy control subjects. This specific modulation enhanced bidirectionally effective connectivity between the cerebellum and primary sensorimotor cortex in stroke patients, which may compensate for the attenuated effective connectivity between cortical and subcortical areas during passive motor task and, consequently, contribute to improvement of movement coordination and motor learning in subacute stroke patients. Our results suggested that further efficacy studies of acupuncture in motor recovery can focus on the improvement of movement coordination and motor learning during motor rehabilitation.

    Abstract:

    The disturbance of balance function is one of main etiology resulting in falling down in stroke patients. A number of studies report that acupuncture may improve the motor function of stroke patients. Therefore, the aim of the present study was to investigate the effect of acupuncture on balance function. We designed a single-blinded, controlled, randomized study. A total of 30 stroke patients were randomized into experimental and control groups. Experimental groups received acupuncture treatment accompanied by the manual twisting of needles and obtaining of qi (the subjects experienced sensations of soreness, numbness, swelling and heaviness, while the acupuncturist experienced a sensation of needle resistance), whereas the control group did not receive manual twisting of needles and without obtaining of qi. All of the subjects were first-time stroke patients; infarction location was limited to either the left or right hemisphere, and all subjects were able to walk for at least 6 meters. Acupuncture stimulation (AS) was applied to Baihui (GV 20) acupoint as well as to 4 spirit acupoints (1.5 cun anterior, posterior, left and right laterals from Baihui acupoint, respectively) for 20 min. Balance function outcome measures were: (1) the displacement area of the patient's center of gravity; (2) the time taken for a patient to stand vertically from a seated position; (3) the time taken for a patient to walk a distance of 6 meters; (4) muscle strength of both lower extremities. Results indicated that the displacement area from the center of gravity decreased in the experimental group, but not in the control group. There was greater reduction in the displacement area in the experimental group than in the control group. Following AS, the time taken to reach a standing position from a seated position, as well as the time taken to walk 6 meters was decreased equally in both the experimental and control groups. The muscle strength of the hip flexor and knee extensor were increased in the paralyzed and non-paralyzed sides of patients in the experimental group, but not in the control group. The results of the present study suggest that acupuncture stimulation may induce an immediate effect that improves balance function in stroke patients.

    Abstract:

    Acupuncture is one of the most important parts of Traditional Chinese Medicine, has been used for more than 3000 years as prevention and treatment for various diseases in China as well as in adjacent regions, and is widely accepted in western countries in recent years. More and more clinical trials revealed that acupuncture shows positive effect in stroke, not only as a complementary and alternative medicine for poststroke rehabilitation but also as a preventive strategy which could induce cerebral ischemic tolerance, especially when combined with modern electrotherapy. Acupuncture has some unique characteristics, which include acupoint specificity and parameter-dependent effect. It also involves complicated mechanism to exert the beneficial effect on stroke. Series of clinical trials have shown that acupuncture primarily regulates the release of neurochemicals, hemorheology, cerebral microcirculation, metabolism, neuronal activity, and the function of specific brain region. Animal studies showed that the effects of acupuncture therapy on stroke were possibly via inhibition of postischemic inflammatory reaction, stimulation of neurogenesis and angiogenesis, and influence on neural plasticity. Mechanisms for its preconditioning effect include activity enhancement of antioxidant, regulation of the endocannabinoid system, and inhibition of apoptosis. Although being controversial, acupuncture is a promising preventive and treatment strategy for stroke, but further high-quality clinical trials would be needed to provide more confirmative evidence.

    Alternative therapies for stroke image

    My 70-year-old uncle suffered a stroke a few weeks ago. He is doing well but struggling with his movement, balance and basic tasks. It also takes him a lot longer to process and understand things. Are there any complementary and alternative therapies that are effective for stroke recovery? — T.W., via email

    The injury to the brain caused by a stroke can lead to problems with talking, seeing, thinking, remembering, moving, eating, swallowing and more. It's no wonder stroke is a leading cause of disability in adults worldwide.1


    But there are a number of complementary and alternative therapies showing promise for limiting and even reversing some of the damage—especially if used in the early stages following a stroke.

    Abstract:

    Curcumin is widely consumed in Asia either as turmeric directly or as one of the culinary ingredients in food recipes. The benefits of curcumin in different organ systems have been reported extensively in several neurological diseases and cancer. Curcumin has got its global recognition because of its strong antioxidant, anti-inflammatory, anti-cancer, and antimicrobial activities. Additionally, it is used in diabetes and arthritis as well as in hepatic, renal, and cardiovascular diseases. Recently, there is growing attention on usage of curcumin to prevent or delay the onset of neurodegenerative diseases. This review summarizes available data from several recent studies on curcumin in various neurological diseases such as Alzheimer's disease, Parkinson's disease, Multiple Sclerosis, Huntington's disease, Prions disease, stroke, Down's syndrome, autism, Amyotrophic lateral sclerosis, anxiety, depression, and aging. Recent advancements toward increasing the therapeutic efficacy of curcuma/curcumin formulation and the novel delivery strategies employed to overcome its minimal bioavailability and toxicity studies have also been discussed. This review also summarizes the ongoing clinical trials on curcumin for different neurodegenerative diseases and patent details of curcuma/curcumin in India.

    Abstract:

    OBJECTIVE:To determine the comparative effectiveness of exercise versus drug interventions on mortality outcomes.

    DESIGN:Metaepidemiological study.

    ELIGIBILITY CRITERIA:Meta-analyses of randomised controlled trials with mortality outcomes comparing the effectiveness of exercise and drug interventions with each other or with control (placebo or usual care).

    DATA SOURCES:Medline and Cochrane Database of Systematic Reviews, May 2013.

    MAIN OUTCOME MEASURE:Mortality.

    DATA SYNTHESIS:We combined study level death outcomes from exercise and drug trials using random effects network meta-analysis.

    RESULTS:We included 16 (four exercise and 12 drug) meta-analyses. Incorporating an additional three recent exercise trials, our review collectively included 305 randomised controlled trials with 339 274 participants. Across all four conditions with evidence on the effectiveness of exercise on mortality outcomes (secondary prevention of coronary heart disease, rehabilitation of stroke, treatment of heart failure, prevention of diabetes), 14 716 participants were randomised to physical activity interventions in 57 trials. No statistically detectable differences were evident between exercise and drug interventions in the secondary prevention of coronary heart disease and prediabetes. Physical activity interventions were more effective than drug treatment among patients with stroke (odds ratios, exercise vanticoagulants 0.09, 95% credible intervals 0.01 to 0.70 and exercise v antiplatelets 0.10, 0.01 to 0.62). Diuretics were more effective than exercise in heart failure (exercise v diuretics 4.11,1.17to 24.76). Inconsistency between direct and indirect comparisons was not significant.

    CONCLUSIONS:Although limited in quantity, existing randomised trial evidence on exercise interventions suggests that exercise and many drug interventions are often potentially similar in terms of their mortality benefits in the secondary prevention of coronary heart disease, rehabilitation after stroke, treatment of heart failure, and prevention of diabetes.

    Abstract:

    OBJECTIVE:To observe the effect of acupuncture (Acupunct) on cerebral infarction volume and expression of poly ADP ribose polymerase 1 (PARP1), apoptosis-inducing factor (AIF) and endonuclease G (Endo-G) in the cerebral cortex tissue at different time-points after cerebral ischemia (CI) in acute cerebral infarction rats, so as to explore its underlying mechanisms in prolonging time window of thrombolysis.

    METHODS:Forty-eight SD rats were randomly divided into sham operation, model, intravenous thrombolysis (IVT)-4.5 h, IVT-6 h, IVT-9 h, Acupunct+IVT-4.5 h, Acupunct +IVT-6 h, Acupunct+IVT-9 h groups (=6 in each group). The CI model was established by using modified autologous thromboembolism via the right common carotid artery. Two hours after modeling, rats of the Acupunct groups received Acupunct stimulation of"Shuigou"(GV26) and bilateral"Neiguan"(PC6) for 30 min. Thrombolysis was conducted by injection of recombinant human tissue-type plasminogen activator (rt-PA, 10 mg/kg) via caudal vein. The neurological deficit was assessed with reference to Bederson's methods. 2,3,5-triphenyltetrazolium chloride (TTC) staining was used to assess the cerebral infarction volume, and the expression of cerebral PARP1, AIF and Endo-G proteins detected by Western blot.

    RESULTS:Compared with the sham operation group, the neurological score and percentage of cerebral infarction volume, expression levels of PARP1, AIF and Endo-G proteins were significantly increased in the model group (<0.01,<0.05). After the intervention, modeling-induced increase of the aforementioned indexes was reversed in the IVT-4.5 h, Acupunct+IVT-4.5 h and Acupunct+IVT-6 h groups (<0.05), except PARP1 expression of the Acupunct+IVT 6 h group (>0.05). The levels of neurological score, percentage of cerebral infarction volume, and AIF expression were significantly lower in both the Acupunct+IVT 4.5 h and Acupunct+IVT-6 h groups than in the simple IVT-4.5 h and simple IVT-6 h groups, respectively (<0.05), and the expression levels of PARP1 and Endo-G proteins were obviously lower in the Acupunct+IVT-4.5 h group than in the IVT-4.5 h group (<0.05). Endo-G proteins were obviously lower in the Acupunct+IVT-9 h group than in the IVT-9 h group (<0.05).

    CONCLUSION:Acupuncture may improve neurological function, reduce cerebral infarction volume and prolong the time window of thrombolysis in CI rats, which may be associated with its effect in suppressing AIF/PARP1/ Endo-G signaling.

    Abstract:

    OBJECTIVES:To determine whether the combination of acupuncture and rehabilitation produces better results in the treatment of acute or subacute stroke sequelae than rehabilitation alone.

    METHODS:A systematic review was carried out. A search was conducted in March 2014 using PubMed, Medline, the Cochrane Library, Chinese National Knowledge Infrastructure database (CNKI) and Wanfang databases. English and Chinese language articles published within 10 years of the search were reviewed for inclusion. Randomised control trials comparing combined treatment with acupuncture and rehabilitation and rehabilitation alone in patients with acute or subacute stroke (onset until 3 months after stroke) were included in this review. Three review authors independently checked the titles and abstracts of trials for inclusion based on selection criteria. Studies measuring changes of motor function, activities of daily living, neurological deficit or spasticity/range of motion during the treatment period and at the end of follow-up were included.

    RESULTS:17 trials met the inclusion criteria, of which five were of good quality. 14 trials had results favourable to acupuncture combined with rehabilitation, compared with conventional rehabilitation treatment alone.

    CONCLUSIONS:Acupuncture in combination with rehabilitation may have benefits for the treatment of acute and subacute stroke sequelae in comparison with rehabilitation alone. However, many of the studies were at risk of bias. Future studies should focus on reaching a consensus about the most appropriate modality of acupuncture intervention, and the appropriate length of treatment for both interventions, to maximise the potential synergistic outcomes.

    Seung-Hoon Lee, Yun-Hee Kim, Young-Ju Kim, Byung-Woo Yoon

    Abstract:

    BACKGROUND: Cerebral ischemia increases neurogenesis in the subventricular zone (SVZ) and in the subgranular zone (SGZ) of the dentate gyrus, and this might be modulated by an enriched environment including voluntary physical activity. We examined whether enforced physical training (EPT) influences neurogenesis in the SVZ and SGZ after cerebral ischemia.

    METHODS: Adult male Sprague-Dawley rats were subjected to focal cerebral ischemia for 2 h, and divided into an EPT and a non-EPT group. All rats in the EPT group were trained using a rota-rod for 14 days. 5-bromo-2'-deoxyuridine (BrdU) was injected to determine levels of cell proliferation. Functional recovery was assessed using a set of behavioral test batteries. Extents of endogenous neurogenesis in the SVZ and SGZ were quantified by immunofluorescence staining. Although final infarction volumes were not significantly different in the groups, functional recovery was better in the EPT group at 10 and 17 days after ischemia. In the SVZ, BrdU labeling and double labeling of BrdU/Dcx and of BrdU/NeuN were not significantly different in the two groups. However, in the SGZ, EPT significantly increased the number of BrdU-positive cell numbers (EPT vs. non-EPT: 159.1+/-19.9 vs. 101.8+/-7.8, p=0.04), and the number of BrdU/Dcx double-labeled cells (130.6+/-16.9 vs. 73.6+/-7.2, p=0.01).

    CONCLUSIONS: The results obtained indicate that EPT promotes neurogenesis in the SGZ of the dentate gyrus after ischemia, but not in the SVZ. The biochemical mechanism that determines the differential effects of EPT remains to be clarified.

    Abstract:

    Humans in modern societies typically consume food at least three times daily, while laboratory animals are fed ad libitum. Overconsumption of food with such eating patterns often leads to metabolic morbidities (insulin resistance, excessive accumulation of visceral fat, etc.), particularly when associated with a sedentary lifestyle. Because animals, including humans, evolved in environments where food was relatively scarce, they developed numerous adaptations that enabled them to function at a high level, both physically and cognitively, when in a food-deprived/fasted state. Intermittent fasting (IF) encompasses eating patterns in which individuals go extended time periods (e.g., 16-48h) with little or no energy intake, with intervening periods of normal food intake, on a recurring basis. We use the term periodic fasting (PF) to refer to IF with periods of fasting or fasting mimicking diets lasting from 2 to as many as 21 or more days. In laboratory rats and mice IF and PF have profound beneficial effects on many different indices of health and, importantly, can counteract disease processes and improve functional outcome in experimental models of a wide range of age-related disorders including diabetes, cardiovascular disease, cancers and neurological disorders such as Alzheimer's disease Parkinson's disease and stroke. Studies of IF (e.g., 60% energy restriction on 2days per week or every other day), PF (e.g., a 5day diet providing 750-1100kcal) and time-restricted feeding (TRF; limiting the daily period of food intake to 8h or less) in normal and overweight human subjects have demonstrated efficacy for weight loss and improvements in multiple health indicators including insulin resistance and reductions in risk factors for cardiovascular disease. The cellular and molecular mechanisms by which IF improves health and counteracts disease processes involve activation of adaptive cellular stress response signaling pathways that enhance mitochondrial health, DNA repair and autophagy. PF also promotes stem cell-based regeneration as well as long-lasting metabolic effects. Randomized controlled clinical trials of IF versus PF and isoenergetic continuous energy restriction in human subjects will be required to establish the efficacy of IF in improving general health, and preventing and managing major diseases of aging.

    Abstract:

    We report a 75-year-old male patient who suffered posterior circulation ischaemia after influenza A/H1N1 vaccination. Vaccination provokes a variable magnitude of inflammatory and immunological response that modifies the risk for ischaemic stroke. Whereas a causal relation between vaccination and ischaemic stroke is still unsettled, an inflammatory/immunological response after vaccination may trigger thrombosis superimposing a pre-existing prothrombotic state. Careful monitoring is strongly suggested for individuals who received H1N1 vaccine, especially those with high ischaemic stroke risk.

    METHODS:Literature searches were performed in 7 databases up to 16 August 2014, and all the randomized controlled trials (RCTs) in which SA therapy was administered to stroke patients were selected. Methodological quality was assessed using the Jadad score, the Cochrane risk of bias assessment, and the Standards for Reporting Interventions in Clinical Trials of Acupuncture.

    RESULTS:Of a total of 2086 papers, 21 RCTs were selected. Meta-analysis revealed significant differences in the total efficacy rates of the SA group and the body acupuncture (BA) group vs the medication group (P<0.002, P<0.000 001, respectively), the SA plus BA group vs the BA group (P<0.001); in the motor function of the SA plus BA group vs the BA group (P = 0.077); and in the nerve function of the SA group vs the SA plus BA group (P<0.0001).

    CONCLUSION:The results of our systematic review showed that SA therapy may exhibit effects in treatment efficacy and in the recovery of motor and nervous functions in patients with acute to chronic stroke. However, because of the lack of methodological quality, the thoroughly planned clinical studies are still required.

    Abstract:

    BACKGROUND: Acquired brain injury (ABI) can result in impairments in motor function, language, cognition, sensory processing and emotional disturbances. This may severely reduce a survivor's quality of life. Music therapy has been used in rehabilitation to stimulate brain functions involved in movement, cognition, speech, emotions and sensory perceptions. A systematic review is needed to gauge the efficacy of music therapy as a rehabilitation intervention for people with ABI. OBJECTIVES: To examine the effects of music therapy with standard care versus standard care alone or standard care combined with other therapies on gait, upper extremity function, communication, mood and emotions, social skills, pain, behavioral outcomes, activities of daily living and adverse events. SEARCH STRATEGY: We searched the Cochrane Stroke Group Trials Register (February 2010), the Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 2, 2009), MEDLINE (July 2009), EMBASE (August 2009), CINAHL (March 2010), PsycINFO (July 2009), LILACS (August 2009), AMED (August 2009) and Science Citation Index (August 2009). We handsearched music therapy journals and conference proceedings, searched dissertation and specialist music databases, trials and research registers, reference lists, and contacted experts and music therapy associations. There was no language restriction. SELECTION CRITERIA: Randomized and quasi-randomized controlled trials that compared music therapy interventions and standard care with standard care alone or combined with other therapies for people older than 16 years of age who had acquired brain damage of a non-degenerative nature and were participating in treatment programs offered in hospital, outpatient or community settings. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed methodological quality and extracted data. We present results using mean differences (using post-test scores) as all outcomes were measured with the same scale. MAIN RESULTS: We included seven studies (184 participants). The results suggest that rhythmic auditory stimulation (RAS) may be beneficial for improving gait parameters in stroke patients, including gait velocity, cadence, stride length and gait symmetry. These results were based on two studies that received a low risk of bias score. There were insufficient data to examine the effect of music therapy on other outcomes. AUTHORS' CONCLUSIONS: RAS may be beneficial for gait improvement in people with stroke. These results are encouraging, but more RCTs are needed before recommendations can be made for clinical practice. More research is needed to examine the effects of music therapy on other outcomes in people with ABI.

    Abstract:

    Motor impairments are common after stroke, but efficacious therapies for these dysfunctions are scarce. By extending an earlier study on the effects of music-supported therapy, behavioral indices of motor function as well as electrophysiological measures were obtained before and after a series of therapy sessions to assess whether this new treatment leads to neural reorganization and motor recovery in patients after stroke. The study group comprised 32 stroke patients in a large rehabilitation hospital; they had moderately impaired motor function and no previous musical experience. Over a period of 3 weeks, these patients received 15 sessions of music-supported therapy using a manualized step-by-step approach. For comparison 30 additional patients received standard rehabilitation procedures. Fine as well as gross motor skills were trained by using either a MIDI-piano or electronic drum pads programmed to emit piano tones. Motor functions were assessed by an extensive test battery. In addition, we studied event-related desynchronization/synchronization and coherences from all 62 patients performing self-paced movements of the index finger (MIDI-piano) and of the whole arm (drum pads). Results showed that music-supported therapy yielded significant improvement in fine as well as gross motor skills with respect to speed, precision, and smoothness of movements. Neurophysiological data showed a more pronounced event-related desynchronization before movement onset and a more pronounced coherence in the music-supported therapy group in the post-training assessment, whereas almost no differences were observed in the control group. Thus we see that music-supported therapy leads to marked improvements of motor function after stroke and that these are accompanied by electrophysiological changes indicative of a better cortical connectivity and improved activation of the motor cortex.

    Abstract:

    Background: Human placenta-derived adherent (PDA001) cells are mesenchymal-like stem cells isolated from postpartum human placenta. In this study, we tested whether intravenously-infused PDA001 improves neurological functional recovery after stroke in rats. In addition, potential mechanisms underlying the PDA001-induced neuroprotective effect were investigated.Methods: Young adult male rats (2-3 months) were subjected to 2h of middle cerebral artery occlusion (MCAo) and treated with PDA001 (4x10⁶) or vehicle controls (Dextran vehicle or phosphate buffer saline (PBS)) via intravenous (IV) administration initiated at 4h after MCAo. A battery of functional tests and measurements of lesion volume and apoptotic cells were performed. Immunostaining and ELISA assays for vascular endothelial growth factor (VEGF) and hepatocyte growth factor (HGF) and brain-derived neurotrophic factor (BDNF) were performed in the ischemic brain to test the potential mechanisms underlying the neuroprotective effects of PDA001 cell treatment of stroke.Results: PDA001 cell treatment at 4h post stroke significantly improved functional outcome, and as well as significantly decreased lesion volume, TUNEL and cleaved-Caspase-3 positive cell number in the ischemic brain, compared to MCAo-vehicle and MCAo-PBS control. Treatment of stroke with PDA001 cells also significantly increased HGF and VEGF expression inthe ischemic border zone (IBZ) compared to controls. Using ELISA assays, treatment of stroke with PDA001 cells significantly increased VEGF, HGF and BDNF levels in the ischemic brain compared to controls.Conclusion: When administered intravenously at 4h after MCAo, PDA001 cells promoted neuroprotective effects. These effects induced by PDA001 cell treatment may be related to the increase of VEGF, HGF and BDNF expression and a decrease of apoptosis. PDA001 cells may provide a viable cell source to treat stroke.

    Abstract:

    BACKGROUND: Among the naturally occurring compounds, turmeric from the dried rhizome of the plant Curcuma longa has long been used extensively as a condiment and a household remedy all over Southeast Asia. Turmeric contains essential oil, yellow pigments (curcuminoids), starch and oleoresin. The present study was designed for investigating the neuroprotective efficacy and the time window for effective therapeutic use of Curcuma oil (C. oil). METHOD: In the present study, the effect of post ischemic treatment of C.oil after ischemia induced by occlusion of the middle cerebral artery in the rat was observed. C.oil (500 mg/kg body wt) was given 4 hrs post ischemia. The significant effect on lesion size as visualized by using diffusion-weighted magnetic resonance imaging and neuroscore was still evident when treatment was started 4 hours after insult. Animals were assessed for behavioral deficit scores after 5 and 24 hours of ischemia. Subsequently, the rats were sacrificed for evaluation of infarct and edema volumes and other parameters. RESULTS: C.oil ameliorated the ischemia induced neurological functional deficits and the infarct and edema volumes measured after 5 and 24 hrs of ischemia. After 24 hrs, immunohistochemical and Western blot analysis demonstrated that the expression of iNOS, cytochrome c and Bax/Bcl-2 were altered after the insult, and antagonized by treatment with C.oil. C.oil significantly reduced nitrosative stress, tended to correct the decreased mitochondrial membrane potential, and also affected caspase-3 activation finally apoptosis. CONCLUSION: Here we demonstrated that iNOS-derived NO produced during ischemic injury was crucial for the up-regulation of ischemic injury targets. C.oil down-regulates these targets this coincided with an increased survival rate of neurons.
