Abstract
Some of the greatest challenges in medicine are the neurodegenerative diseases (NDs), which remain without a cure and mostly progress to death. A companion study employed a toolkit methodology to document 2001 plant species with ethnomedicinal uses for alleviating pathologies relevant to NDs, focusing on its relevance to Alzheimer's disease (AD). This study aimed to find plants with therapeutic bioactivities for a range of NDs. 1339 of the 2001 plant species were found to have a bioactivity from the literature of therapeutic relevance to NDs such as Parkinson's disease, Huntington's disease, AD, motor neurone diseases, multiple sclerosis, prion diseases, Neimann-Pick disease, glaucoma, Friedreich's ataxia and Batten disease. 43 types of bioactivities were found, such as reducing protein misfolding, neuroinflammation, oxidative stress and cell death, and promoting neurogenesis, mitochondrial biogenesis, autophagy, longevity, and anti-microbial activity. Ethno-led plant selection was more effective than random selection of plant species. Our findings indicate that ethnomedicinal plants provide a large resource of ND therapeutic potential. The extensive range of bioactivities validate the usefulness of the toolkit methodology in the mining of this data. We found that a number of the documented plants are able to modulate molecular mechanisms underlying various key ND pathologies, revealing a promising and even profound capacity to halt and reverse the processes of neurodegeneration.

Abstract
Traumatic spinal cord injury (TSCI) is a serious nervous system insult, and apoptosis in secondary injury is an important barrier to recovery from TSCI. Heat shock protein family A member 1A (HSPA1A) is a protective protein whose expression is elevated after stress. However, whether HSPA1A can inhibit apoptosis after spinal cord injury, and the potential mechanism of this inhibition, remain unclear. In this study, we established in vivo and in vitro models of TSCI and induced HSPA1A overexpression and silencing. HSPA1A upregulation promoted the recovery of neurological function and pathological morphology at the injury site, enhanced neurological cell survival, and inhibited apoptosis in rats following TSCI. In the in vitro model, HSPA1A overexpression inhibited H2O2-induced apoptosis, indicating that HSPA1A suppressed the expression of Bax, caspase-9, and cleaved-caspase-3, promoted the expression of Bcl-2. Furthermore, inhibition of HSPA1A expression can aggravate H2O2-induced apoptosis. We also found that HSPA1A overexpression activated the Wnt/β-catenin signaling pathway, and that inhibition of this pathway attenuated the inhibitory effect of HSPA1A overexpression on apoptosis. Together, these results indicate that HSPA1A has neuroprotective effects against TSCI that may be exerted through activation of the Wnt/β-catenin signaling pathway to inhibit apoptosis.

Abstract
Spinal cord injury (SCI) is a devastating central nervous system disease, caused by physical traumas. With the characteristic of high disability rate, catastrophic dysfunction, and enormous burden on the patient’s family, SCI has become a tough neurological problem without efficient treatments. Contemporarily, the pathophysiology of SCI comprises complicated and underlying mechanisms, in which oxidative stress (OS) may play a critical role in contributing to a cascade of secondary injuries. OS substantively leads to ion imbalance, lipid peroxidation, inflammatory cell infiltration, mitochondrial disorder, and neuronal dysfunction. Hence, seeking the therapeutic intervention of alleviating OS and appropriate antioxidants is an essential clinical strategy. Previous studies have reported that traditional Chinese medicine (TCM) has antioxidant, anti-inflammatory, antiapoptotic and neuroprotective effects on alleviating SCI. Notably, the antioxidant effects of some metabolites and compounds of TCM have obtained numerous verifications, suggesting a potential therapeutic strategy for SCI. This review aims at investigating the mechanisms of OS in SCI and highlighting some TCM with antioxidant capacity used in the treatment of SCI.

Abstract
Spinal cord injury (SCI) is a significant cause of disability, and treatment alternatives that generate beneficial outcomes and have no side effects are urgently needed. SCI may be treatable if intervention is initiated promptly. Therefore, several treatment proposals are currently being evaluated. Inflammation is part of a complex physiological response to injury or harmful stimuli induced by mechanical, chemical, or immunological agents. Neuroinflammation is one of the principal secondary changes following SCI and plays a crucial role in modulating the pathological progression of acute and chronic SCI. This review describes the main inflammatory events occurring after SCI and discusses recently proposed potential treatments and therapeutic agents that regulate inflammation after insult in animal models.

Abstract
Alzheimer's disease (AD) is progressive and ultimately fatal, with current drugs failing to reverse and cure it. This study aimed to find plant species which may provide therapeutic bioactivities targeted to causal agents proposed to be driving AD. A novel toolkit methodology was employed, whereby clinical symptoms were translated into categories recognized in ethnomedicine. These categories were applied to find plant species with therapeutic effects, mined from ethnomedical surveys. Survey locations were mapped to assess how this data is at risk. Bioactivities were found of therapeutic relevance to 15 hypothesised causal bases for AD. 107 species with an ethnological report of memory improvement demonstrated therapeutic activity for all these 15 causal bases. The majority of the surveys were found to reside within biodiversity hotspots (centres of high biodiversity under threat), with loss of traditional knowledge the most common threat. Our findings suggest that the documented plants provide a large resource of AD therapeutic potential. In demonstrating bioactivities targeted to these causal bases, such plants may have the capacity to reduce or reverse AD, with promise as drug leads to target multiple AD hallmarks. However, there is a need to preserve ethnomedical knowledge, and the habitats on which this knowledge depends.

Abstract
Allicin is the main active ingredient in freshly-crushed garlic and some other allium plants, and its anticancer effect on cancers of digestive system has been confirmed in many studies. The aim of this review is to summarize epidemiological studies and in vitro and in vivo investigations on the anticancer effects of allicin and its secondary metabolites, as well as their biological functions. In epidemiological studies of esophageal cancer, liver cancer, pancreatic cancer, and biliary tract cancer, the anticancer effect of garlic has been confirmed consistently. However, the results obtained from epidemiological studies in gastric cancer and colon cancer are inconsistent. In vitro studies demonstrated that allicin and its secondary metabolites play an antitumor role by inhibiting tumor cell proliferation, inducing apoptosis, controlling tumor invasion and metastasis, decreasing angiogenesis, suppressing Helicobacter pylori, enhancing the efficacy of chemotherapeutic drugs, and reducing the damage caused by chemotherapeutic drugs. In vivo studies further demonstrate that allicin and its secondary metabolites inhibit cancers of the digestive system. This review describes the mechanisms against cancers of digestive system and therapeutic potential of allicin and its secondary metabolites.

Abstract
Environmental pollutants and especially metal trace elements remain an unmitigated threat to the overall life support system. Their chemical stability and accumulation pattern in the ecosystem make them a persistent hazard. This study aims to characterize the early cadmium (Cd) histological and hematological alterations and their corresponding plasma indicators in the Mediterranean sea bass (Dicentrarchus labrax). We also assessed garlic potential to prevent cadmium toxicity. For this purpose, 200 fish of 55 g mean weight were separated into 3 cylindroconical fiberglass tanks of 500-L capacity, each with a stocking density of 4 kg m-3. The fish were regularly hand-fed 0% (control group), 2%, and 6% garlic-supplemented diets to apparent satiation twice a day for 1 month. At the end of the experiment, we injected 22.2 mM cadmium (CdCl2) intraperitoneally to the experimental groups and a placebo solution (9% NaCl) to the control groups; liver, kidney, heart, and blood tissue alterations were monitored with a full screening of their plasmatic indicators, 24 h before and 48 h after Cd injection. Subsequently, whole blood count and blood smears were performed to follow up on Cd-induced vascular damages. Our data showed that Cd induced thrombotic thrombocytopenic purpura, leading to widespread bleeding and cellular alterations in the targeted tissues. These alterations were associated with an obvious normochromic normocytic anemia in favor of microangiopathic hemolytic anemia. Cd injection has also seriously inhibited the overall enzymatic activities triggering a metabolic shift. Although garlic supplementation had little effect on cadmium-induced alterations, it significantly reduced biomass dispersion. Our data is the first evidence of the cadmium versatile toxicity involving vascular alterations as a central and a leading cause of the overall parenchymal lesions. Cd toxicity was associated with a specific enzymatic signature, which must be considered during the interpretation.

Abstract
The aim of this study was to evaluate the chemical compounds of garlic essential oil (EO), and determine the antifungal efficacy of garlic EO and its major components, diallyl trisulfide and its nanoemulsions against wood-rotting fungi, Trametes hirsuta and Laetiporus sulphureus. GC-MS analysis revealed that the major constituents of garlic EO were diallyl trisulfide (39.79%), diallyl disulfide (32.91%), and diallyl sulfide (7.02%). In antifungal activity, the IC50 value of garlic EO against T. hirsuta and L. sulphureus were 137.3 and 44.6 μg/mL, respectively. Results from the antifungal tests demonstrated that the three major constituents were shown to have good antifungal activity, in which, diallyl trisulfide was the most effective against T. hirsuta and L. sulphureus, with the IC50 values of 56.1 and 31.6 μg/mL, respectively. The diallyl trisulfide nanoemulsions showed high antifungal efficacy against the examined wood-rotting fungi, and as the amount of diallyl trisulfide in the lipid phase increases, the antifungal efficacy of the nanoemulsions increases. These results showed that the nanoemulsions and normal emulsion of diallyl trisulfide have potential to develop into a natural wood preservative.

Abstract
BACKGROUND Allium sativum L., or garlic, is one of the most studied plants worldwide within the field of traditional medicine. Current interests lie in the potential use of garlic as a preventive measure and adjuvant treatment for viral infections, e.g., SARS-CoV-2. Even though it cannot be presented as a single treatment, its beneficial effects are beyond doubt. The World Health Organization has deemed it an essential part of any balanced diet with immunomodulatory properties. OBJECTIVE The aim of the study was to review the literature on the effects of garlic compounds and preparations on immunomodulation and viral infection management, with emphasis on SARS-CoV-2. METHOD Exhaustive literature search has been carried out on electronic databases. CONCLUSION Garlic is a fundamental part of a well-balanced diet which helps maintain general good health. The reported information regarding garlic's ability to beneficially modulate inflammation and the immune system is encouraging. Nonetheless, more efforts must be made to understand the actual medicinal properties and mechanisms of action of the compounds found in this plant to inhibit or diminish viral infections, particularly SARS-CoV-2. Based on our findings, we propose a series of innovative strategies to achieve such a challenge in the near future.

Abstract
Spinal cord injury (SCI) is a severe traumatic injury of the central nervous system, characterized by neurological dysfunction and locomotor disability. Although the underlying pathological mechanism of SCI is complex and remains unclear, the important role of neuroinflammation has been gradually unveiled in recent years. The inflammation process after SCI involves disruption of the blood–spinal cord barrier (BSCB), activation of gliocytes, infiltration of peripheral macrophages, and feedback loops between different cells. Thus, our first aim is to illustrate pathogenesis, related cells and factors of neuroinflammation after SCI in this review. Due to the good bioactivity of natural products derived from plants and medicinal herbs, these widely exist as food, health-care products and drugs in our lives. In the inflammation after SCI, multiple natural products exert satisfactory effects. Therefore, the second aim of this review is to sum up the effects and mechanisms of 25 natural compounds and 7 extracts derived from plants or medicinal herbs on neuroinflammation after SCI. Clarification of the SCI inflammation mechanism and a summary of the related natural products is helpful for in-depth research and drug development.

Hormetic Effects of Bioactive Compounds from Foods, Beverages, and Food Dressing: The Potential Role in Spinal Cord Injury. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2021; 2021:6615752. [PMID: 33747346 PMCID: PMC7943269 DOI: 10.1155/2021/6615752] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/10/2020] [Revised: 02/13/2021] [Accepted: 02/20/2021] [Indexed: 01/18/2023]
Abstract
Spinal cord injury (SCI) is a damage or trauma to the spinal cord resulting in a total or partial loss of motor and sensory function. SCI is characterized by a disequilibrium between the production of reactive oxygen species and the levels of antioxidant defences, causing oxidative stress and neuroinflammation. This review is aimed at highlighting the hormetic effects of some compounds from foods, beverages, and food dressing that are able to reduce oxidative stress in patients with SCI. Although curcumin, ginseng, and green tea have been proposed for SCI management, low levels of antioxidant vitamins have been reported in individuals with SCI. Mediterranean diet includes food rich in vitamins and antioxidants. Moreover, food dressing, including spices, herbs, and extra virgin olive oil (EVOO), contains multiple components with hormetic effects. The latter involves the activation of the nuclear factor erythroid-derived 2, consequently increasing the antioxidant enzymes and decreasing inflammation. Furthermore, EVOO improves the bioavailability of carotenoids and could be a delivery system for bioactive compounds. In conclusion, Mediterranean dressing in addition to plant foods can have an important effect on redox balance in individuals with SCI.

Use of medicinal plants for headache, and their potential implication in medication-overuse headache: Evidence from a population-based study in Nepal. Cephalalgia 2021; 41:561-581.

Abstract
Background In Nepal, traditional treatment using medicinal plants is popular. Whereas
medication-overuse headache is, by definition, caused by excessive use of
acute headache medication, we hypothesized that medicinal plants, being
pharmacologically active, were as likely a cause. Methods We used data from a cross-sectional, nationwide population-based study, which
enquired into headache and use of medicinal plants and allopathic
medications. We searched the literature for pharmacodynamic actions of the
medicinal plants. Results Of 2100 participants, 1794 (85.4%) reported headache in the preceding year;
161 (7.7%) reported headache on ≥15 days/month, of whom 28 (17.4%) had used
medicinal plants and 117 (72.7%) allopathic medication(s). Of 46 with
probable medication-overuse headache, 87.0% (40/46) were using allopathic
medication(s) and 13.0% (6/46) medicinal plants, a ratio of 6.7:1, higher
than the overall ratio among those with headache of 4.9:1 (912/185). Of 60
plant species identified, 49 were pharmacodynamically active on the central
nervous system, with various effects of likely relevance in
medication-overuse headache causation. Conclusions MPs are potentially a cause of medication-overuse headache, and not to be
seen as innocent in this regard. Numbers presumptively affected in Nepal are
low but not negligible. This pioneering project provides a starting point
for further research to provide needed guidance on use of medicinal plants
for headache.

Abstract
According to investigations in phytomedicine and ethnopharmacology, the therapeutic properties of garlic (Allium sativum) have been described by ancestral cultures. Notwithstanding, it is of particular concern to elucidate the molecular mechanisms underlying this millenary empirical knowledge. Allicin (S-allyl prop-2-ene-1-sulfinothioate), a thioester of sulfenic acid, is one of the main bioactive compounds present in garlic, and it is responsible for the particular aroma of the spice. The pharmacological attributes of allicin integrate a broad spectrum of properties (e.g., anti-inflammatory, immunomodulatory, antibiotic, antifungal, antiparasitic, antioxidant, nephroprotective, neuroprotective, cardioprotective, and anti-tumoral activities, among others). The primary goal of the present article is to review and clarify the common molecular mechanisms by which allicin and its derivates molecules may perform its therapeutic effects on cardiovascular diseases and neuroinflammatory processes. The intricate interface connecting the cardiovascular and nervous systems suggests that the impairment of one organ could contribute to the dysfunction of the other. Allicin might target the cornerstone of the pathological processes underlying cardiovascular and neuroinflammatory disorders, like inflammation, renin-angiotensin-aldosterone system (RAAS) hyperactivation, oxidative stress, and mitochondrial dysfunction. Indeed, the current evidence suggests that allicin improves mitochondrial function by enhancing the expression of HSP70 and NRF2, decreasing RAAS activation, and promoting mitochondrial fusion processes. Finally, allicin represents an attractive therapeutic alternative targeting the complex interaction between cardiovascular and neuroinflammatory disorders.

Abstract
PURPOSE This study was designed to evaluate the protective effects of allicin against diclofenac sodium induced hepatonephro toxicity in rats. METHODS Sixty male Wister albino rats were assigned into six groups. The control group received calcium carbonate and corn starch. 2nd group received diclofenac sodium (2 mg/kg bw orally) for 30 days. 3rd group received allicin (45 mg/kg bw orally) for 30 days. 4th group administrated diclofenac sodium as in the 2nd group and allicin (15 mg/kg bw orally) for 30 days. 5th group received diclofenac sodium as in the 2nd group and allicin (30 mg/kg bw orally) for 30 days. 6th group received diclofenac sodium as 2nd and allicin (45 mg/kg bw orally) for 30 days. RESULTS Diclofenac sodium significantly elevated activities of serum aspartate aminotransferase and alanine aminotransferase and serum levels of creatinine and urea. In addition, it induced hyperglycemia, lipid peroxidation, pathological alteration and caspase 3 protein expression in hepatic and renal tissues. However, it decreased reduced glutathione concentration and proliferating cell nuclear antigen protein expression in hepatic tissues. In contrast, allicin modulated the diclofenac sodium induced alteration in liver and kidney functions and structures dose dependently. CONCLUSION This study indicated that allicin had potential preventive effects against diclofenac sodium induced hepatonephro toxicity in rats.

Abstract
Patients with spinal cord injury (SCI) face devastating health, social, and financial consequences, as well as their families and caregivers. Reducing the levels of reactive oxygen species (ROS) and oxidative stress are essential strategies for SCI treatment. Some compounds from traditional medicine could be useful to decrease ROS generated after SCI. This review is aimed at highlighting the importance of some natural compounds with antioxidant capacity used in traditional medicine to treat traumatic SCI. An electronic search of published articles describing animal models of SCI treated with natural compounds from traditional medicine was conducted using the following terms: Spinal Cord Injuries (MeSH terms) AND Models, Animal (MeSH terms) AND [Reactive Oxygen Species (MeSH terms) AND/OR Oxidative Stress (MeSH term)] AND Medicine, Traditional (MeSH terms). Articles reported from 2010 to 2018 were included. The results were further screened by title and abstract for studies performed in rats, mice, and nonhuman primates. The effects of these natural compounds are discussed, including their antioxidant, anti-inflammatory, and antiapoptotic properties. Moreover, the antioxidant properties of natural compounds were emphasized since oxidative stress has a fundamental role in the generation and progression of several pathologies of the nervous system. The use of these compounds diminishes toxic effects due to their high antioxidant capacity. These compounds have been tested in animal models with promising results; however, no clinical studies have been conducted in humans. Further research of these natural compounds is crucial to a better understanding of their effects in patients with SCI.

Abstract
Tumor necrosis factor-α (TNF-α) is a critical pro-inflammatory cytokine regulating neuroinflammation. At high concentrations, it is toxic to neurons, and such damage is positively correlated with acute and chronic neurological diseases. Our previous studies showed that inhibition of phosphodiesterase 4 (PDE4) attenuated the production of TNF-α induced by lipopolysaccharides in microglial cells. However, whether PDE4 inhibition can block the neurotoxic effects of TNF-α in neuronal cells is unknown. In this study, we investigated the protective effects of FCPR16, a novel PDE4 inhibitor, against TNF-α-induced cellular apoptosis in HT-22 hippocampal neuronal cells. We demonstrated that FCPR16 dose-dependently increased the viability of HT-22 cells exposed to TNF-α insult. Propidium iodide/calcein staining and flow cytometry analysis showed that FCPR16 decreased cell apoptosis triggered by TNF-α. Western blot analysis showed that FCPR16 decreased the level of cleaved caspase 3 and caspase 8, but had no effect on caspase 9. Mechanistically, FCPR16 blocked the TNF-α-induced phosphorylation of c-Jun N-terminal kinase (JNK) in HT-22 cells, and inhibition of JNK showed a similar protective effect as FCPR16. Furthermore, FCPR16 decreased the translocation of nuclear factor-κB (NF-κB) p65 from the cytosol into the nucleus. In addition, FCPR16 decreased the expression of inducible nitric oxide synthase and the production of reactive oxygen species in HT-22 cells exposed to TNF-α. Moreover, knockdown of PDE4B by specific small interfering RNA reduced the apoptosis of HT-22 cells treated with TNF-α. Taken together, our findings suggest that FCPR16 promotes the survival of neuronal cells exposed to TNF-α by suppressing the activation of JNK and NF-κB.

Allicin attenuates early brain injury after experimental subarachnoid hemorrhage in rats. J Clin Neurosci 2019; 63:202-208.

Abstract
Early Brain Injury, rather than Cerebral Vasospasm, has been demonstrated to be more important for patients with Subarachnoid hemorrhage. It is considered that allicin can make sense in a wide range of pharmacological areas and can be taken as a therapeutic method in many pathologic situations. We have explored the potential effect of allicin and possible mechanisms in Early Brain Injury after Experimental Subarachnoid Hemorrhage in Rats. With therapy (70 mg/kg Allicin, rather than 30 mg/kg) 30 min post SAH, groups showed better neurological scores in 24 h. Significant differences could be found in body weight ratio between the SAH + vehicle groups and SAH + Allicin groups. Treatment with 70 mg/kg, not 30 mg/kg, Allicin significantly reduced brain edema and EB extravasation in 24 h after SAH. Assessments in 24 h after SAH showed that treatment with 70 mg/kg Allicin in 30 min after SAH significantly restrained the expression of cleaved caspase-3, mitigated the severity of neuronal degeneration, decreased the proportion of apoptotic neurons and the elevated MDA levels, and increased the suppressed GSH and SOD levels. We demonstrated for the first time that Allicin extenuated brain edema and blood-brain barrier dysfunction, improved neurological outcomes by the suppression of apoptosis and oxidative stress damage after SAH in experimental models, which may shade new light on the treatments of SAH.

Abstract
Garlic (Allium sativum) and allied plant species are rich sources of sulfur compounds. Major roles for garlic and its sulfur constituents include the regulation of vascular homeostasis and the control of metabolic systems linked to nutrient metabolism. Recent studies have indicated that some of these sulfur compounds, such as diallyl trisulfide (DATS), alter the levels of gaseous signalling molecules including nitric oxide (NO), hydrogen sulfide (H2S), and perhaps carbon monoxide (CO) in mammalian tissues. These gases are important in cellular processes associated with the cardiovascular system, inflammation, and neurological functions. Importantly, these studies build on the known biological effects of garlic and associated sulfur constituents. This review highlights our current understanding of the health benefits attributed to edible plants like garlic.

Abstract
BACKGROUND Previous studies have suggested that patients with bipolar disorder might have brain damage. The aim of this study was to investigate the serum levels of brain injury biomarkers and S100A10 in bipolar patients in a manic phase, and evaluate the changes in S100B, neuron specific enolase (NSE), heat shock protein 70 (HSP70) and S100A10 after treatment. METHOD We consecutively enrolled 17 bipolar inpatients in a manic phase and 30 healthy subjects. Serum brain injury biomarkers and S100A10 were measured with assay kits. All patients were evaluated by examining the correlation between brain injury biomarkers and Young Mania Rating Scale (YMRS) scores. RESULT We found significantly decreased S100B levels only in bipolar manic patients after treatment (p=0.002), but S100B levels were not significantly different from those in healthy controls (p>0.05). CONCLUSION Our results indicate there were decreased S100B serum levels in bipolar patients in a manic phase after treatment and that increased serum S100B levels might be a possible indicator of transient disruption of the blood-brain barrier in bipolar patients in a manic phase.

Abstract
Salting-out extraction (SOE) based on lower molecular organic solvent and inorganic salt was considered as a good substitute for conventional polymers aqueous two-phase extraction (ATPE) used for the extraction of some bioactive compounds from natural plants resources. In this study, the ethanol/ammonium sulfate was screened as the optimal SOE system for the extraction and preliminary purification of allicin from garlic. Response surface methodology (RSM) was developed to optimize the major conditions. The maximum extraction efficiency of 94.17% was obtained at the optimized conditions for routine use: 23% (w/w) ethanol concentration and 24% (w/w) salt concentration, 31g/L loaded sample at 25°C with pH being not adjusted. The extraction efficiency had no obvious decrease after amplification of the extraction. This ethanol/ammonium sulfate SOE is much simpler, cheaper, and effective, which has the potentiality of scale-up production for the extraction and purification of other compounds from plant resources.

Abstract
Allicin is a major component of garlic, extracted as an oily liquid. The present study was designed to investigate the beneficial effects of allicin on traumatic spinal cord injury (TSCI) in mice, and whether the effects are mediated via regulation of the heat shock protein 70 (HSP70), v-akt murine thymoma viral oncogene homolog 1 (Akt) and inducible nitric oxide synthase (iNOS) pathways. Adult BALB/c mice (30–40 g) received a laminectomy at the T9 vertebral level as a model of TSCI. In the present study, treatment of the TSCI mice with allicin significantly increased their Basso, Beattie and Bresnahan (BBB) scores (P<0.01) and reduced the spinal cord water content (P<0.01). This protective effect was associated with the inhibition of oxidative stress and inflammatory responses in TSCI mice. Western blot analysis demonstrated that allicin increased the protein levels of HSP70, increased the phosphorylation of Akt and reduced the iNOS protein expression levels in TSCI mice. Additionally, treatment with allicin significantly reduced the levels of ROS and enhanced the NADH levels in TSCI mice. Collectively, these data demonstrate that the effects of allicin on TSCI are mediated via regulation of the HSP70, Akt and iNOS pathways in mice.

Abstract
AIMS This study aims to investigate the effect of allicin on motor functions and histopathologic changes after spinal cord injury and the mechanism underlying its neuroprotective effects. MAIN METHODS The motor function of rats was evaluated with the Basso, Beattie, and Bresna test. Histopathologic changes were evaluated by hematoxylin and eosin and Nissl staining. Spinal cord oxidative stress markers were determined by measuring glutathione and malondialdehyde content and superoxide dismutase activity using commercial kits. Inflammatory factors were determined by measuring tumor necrosis factor-α, interleukin-1β and interleukin-6 using ELISA assay. Apoptosis was examined using TUNEL staining. The effect of allicin on Nrf2 protein levels and localization was assessed using immunofluorescence staining and Western blotting analysis. KEY FINDINGS Results demonstrated that allicin accelerated the motor functional recovery and protected neuron damage against spinal cord injury (SCI). SCI-induced oxidative stress, inflammatory response and cell apoptosis in the spinal cord were also prevented by allicin. In addition, we observed that SCI increased Nrf2 nuclear expression, and allicin treatment further increased Nrf2 nuclear translocation in neurons and astrocytes. siRNA-mediated Nrf2 gene knockdown completely blocked the effect of allicin on spinal cord tissue. SIGNIFICANCE Our finding suggests that allicin promotes the recovery of motor function after SCI in rats, and this effect may be related to its anti-oxidant, anti-inflammatory and anti-apoptotic effects. Allicin mediated Nrf2 nuclear translocation may be involved in the protective effect as well.

Abstract
Endoplasmic reticulum (ER) stress is involved in neurodegenerative diseases including Alzheimer's disease (AD), in which dysregulation of double-stranded RNA-dependent protein kinase (PKR)-like ER-resident kinase (PERK) is considered to play a critical role. Allicin, a garlic extract, has been demonstrated a protective role in AD model. The present study was designed to investigate the possible protective effect of allicin on ER stress-induced cognitive deficits and underlying mechanisms in rats. In this study, 72h of lateral ventricular infusion of tunicamycin (TM), an ER stress stimulator, induced significant cognitive deficits. TM increased tau phosphorylation, Aβ42 deposit, and oxidative stress, and reduced antioxidative enzymes activity in the hippocampus. TM moderately elevated the expression of PERK and its downstream substrate nuclear factor erythroid-derived 2-like 2 (Nrf2) in the hippocampus. All these impaired changes by TM were significantly improved by allicin pretreatment. Allicin markedly increased PERK and Nrf2 expression in the hippocampus. Thus, our data demonstrate the protective role of allicin in ER stress-related cognitive deficits, and suggest that PERK/Nrf2 antioxidative signaling pathway underlies the action mechanism.
