Abstract
Parkinson's disease is a progressive neurodegenerative disorder marked by the death of dopaminergic neurons in the substantia nigra region of the brain. Aggregation of alpha-synuclein (α-synuclein) is a contributing factor to Parkinson's disease pathogenesis. The objective of this study is to investigate the neuroprotective effects of gut microbes on α-synuclein aggregation using both in silico and in vivo approaches. We focussed on the interaction between α-synuclein and metabolites released by gut bacteria that protect from PD. We employed three probiotic microbe strains against α-synuclein protein: Lactobacillus casei, Escherichia coli, and Bacillus subtilis, with their chosen PDB IDs being Dihydrofolate reductase (3DFR), methionine synthetase (6BM5), and tryptophanyl-tRNA synthetase (3PRH), respectively. Using HEX Dock 6.0 software, we examined the interactions between these proteins. Among the various metabolites, methionine synthetase produced by E. coli showed potential interactions with α-synuclein. To further evaluate the neuroprotective benefits of E. coli, an in vivo investigation was performed using a rotenone-induced Parkinsonian mouse model. The motor function of the animals was assessed through behavioural tests, and oxidative stress and neurotransmitter levels were also examined. The results demonstrated that, compared to the rotenone-induced PD mouse model, the rate of neurodegeneration was considerably reduced in mice treated with E. coli. Additionally, histopathological studies provided evidence of the neuroprotective effects of E. coli. In conclusion, this study lays the groundwork for future research, suggesting that gut bacteria may serve as potential therapeutic agents in the development of medications to treat Parkinson's disease. fig. 1.

Abstract
"Path to a good mood lies through the gut." This statement seems to imply that it has long been believed that the gut is connected with the brain. Research has shown that eating food activates the reward system and releases dopamine (DA), establishing a link between the peripheral and central nervous system. At the same time, researchers also trust that the gut is involved in the onset of many diseases, including Parkinson's disease (PD), in which gastrointestinal dysfunction is considered a prevalent symptom. Reports suggest that PD starts from the gut and reaches the brain via the vagus nerve. Recent studies have revealed an intriguing interaction between the gut and brain, which links gut dysbiosis to the etiology of PD. This review aims to explore the mechanistic pathway how reactive oxygen species (ROS) generation in the gut affects the makeup and operation of the dopamine circuitry in the brain. Our primary concern is ROS generation in the gut, which disrupts the gut microbiome (GM), causing α-synuclein accumulation and inflammation. This trio contributes to the loss of DA neurons in the brain, resulting in PD development. This review also compiles pre-clinical and clinical studies on antioxidants, demonstrating that antioxidants reduce ROS and increase DA levels. Collectively, the study highlights the necessity of comprehending the gut-brain axis for unraveling the riddles of PD pathogenesis and considering new therapeutic approaches.

Abstract
Apium graveolens is an indigenous plant in the family Apiaceae, or Umbelliferae, that contains many active compounds. It has been used traditionally to treat arthritic conditions, gout, and urinary infections. The authors conducted a scoping review to assess the quality of available evidence on the overall effects of celery when treating neurological disorders. A systematic search was performed using predetermined keywords in selected electronic databases. The 26 articles included upon screening consisted of 19 in vivo studies, 1 published clinical trial, 4 in vitro studies and 2 studies comprising both in vivo and in vitro methods. A. graveolens and its bioactive phytoconstituent, 3-n-butylphthalide (NBP), have demonstrated their effect on neurological disorders such as Alzheimer's disease, Parkinson's disease, stroke-related neurological complications, depression, diabetes-related neurological complications, and epilepsy. The safety findings were minimal, showing that NBP is safe for up to 18 weeks at 15 mg/kg in animal studies, while there were adverse effects (7%) reported when consuming NBP for 24 weeks at 600 mg daily in human trials. In conclusion, the safety of A. graveolens extract and NBP can be further investigated clinically on different neurological disorders based on their potential role in different targeted pathways.

Evaluation of Potential Neuroprotective Effects of Vanillin Against MPP +/MPTP-Induced Dysregulation of Dopaminergic Regulatory Mechanisms in SH-SY5Y Cells and a Mouse Model of Parkinson's Disease. Mol Neurobiol 2023:10.1007/s12035-023-03358-z.

Abstract
Parkinson's disease (PD) is a progressive neurodegenerative condition. The pathogenesis of PD is still unknown, and drugs available for PD treatment either have side effects or have suboptimal efficacy. Flavonoids are potent antioxidants having little toxicity with extended use, suggesting they might hold promising therapeutic potential against PD. Vanillin (Van) is a phenolic compound that has exhibited neuroprotective properties in various neurological disorders, including PD. However, the neuroprotective role of Van in PD and its underlying mechanisms are scarce and therefore need more exploration. Here, we evaluated the neuroprotective potential of Van and its associated mechanisms against MPP+/MPTP-induced neuronal loss in differentiated human neuroblastoma (SH-SY5Y) cells and the mouse model of PD. In the present study, Van treatment significantly enhanced the cell viability and alleviated oxidative stress, mitochondrial membrane potential, and apoptosis in MPP+-intoxicated SH-SY5Y cells. Moreover, Van significantly ameliorated the MPP+-induced dysregulations in protein expression of tyrosine hydroxylase (TH) and mRNA expressions of GSK-3β, PARP1, p53, Bcl-2, Bax, and Caspase-3 genes in SH-SY5Y cells. Similar to our in vitro results, Van significantly alleviated MPTP-induced neurobehavioral dysregulations, oxidative stress, aberrant TH protein expressions, and immunoreactivity in SNpc of mice brains. Treatment of Van also prevented MPTP-mediated loss of TH-positive intrinsic dopaminergic neurons to SNpc and TH-fibers projecting to the striatum of mice. Thus, Van exhibited promising neuroprotective properties in the current study against MPP+/MPTP-intoxicated SH-SY5Y cells and mice, indicating its potential therapeutic properties against PD pathology.

Abstract
The modulatory interactions between neurotensin (NT) and the dopaminergic neurotransmitter system in the brain suggest that NT may be associated with the progression of Parkinson's disease (PD). NT exerts its neurophysiological effects by interactions with the human NT receptors type 1 (hNTS1) and 2 (hNTS2). Therefore, both receptor subtypes are promising targets for the development of novel NT-based analogs for the treatment of PD. In this study, we used a virtually guided molecular modeling approach to predict the activity of NT(8-13) analogs by investigating the docking models of ligands designed for binding to the human NTS1 and NTS2 receptors. The importance of the residues at positions 8 and/or 9 for hNTS1 and hNTS2 receptor binding affinity was experimentally confirmed by radioligand binding assays. Further in vitro ADME profiling and in vivo studies revealed that, compared to the parent peptide NT(8-13), compound 10 exhibited improved stability and BBB permeability combined with a significant enhancement of the motor function and memory in a mouse model of PD. The herein reported NTS1/NTS2 dual-specific NT(8-13) analogs represent an attractive tool for the development of therapeutic strategies against PD and potentially other CNS disorders.

Abstract
The incidence and prevalence of age-related neurodegenerative dementias have been increasing. There is no curative therapy and conventional drug treatment can cause problems for patients. Medicinal plants traditionally used for problems associated with ageing are emerging as a therapeutic resource. The main aim is to give a proposal for use and future research based on scientific knowledge and tradition. A literature search was conducted in several searchable databases. The keywords used were related to neurodegenerative dementias, ageing and medicinal plants. Boolean operators and filters were used to focus the search. As a result, there is current clinical and preclinical scientific information on 49 species used in traditional medicine for ageing-related problems, including neurodegenerative dementias. There are preclinical and clinical scientific evidences on their properties against protein aggregates in the central nervous system and their effects on neuroinflammation, apoptosis dysregulation, mitochondrial dysfunction, gabaergic, glutamatergic and dopaminergic systems alterations, monoamine oxidase alterations, serotonin depletion and oestrogenic protection. In conclusion, the potential therapeutic effect of the different medicinal plants depends on the type of neurodegenerative dementia and its stage of development, but more clinical and preclinical research is needed to find better, safer and more effective treatments.

Abstract
BACKGROUND Anxiety and depression are crucial public health issues, affecting the rising in hospitalizations and death. Anxiety and depression can worsen hypertension and vice versa. OBJECTIVE The current study has investigated the effects of celery seed extract, as a drug supplement, with the active ingredient of 3-n-butylphthalide, on mental problems primarily anxiety and secondary depression in hypertensive patients. DESIGN The current study was a randomized, triple-blind, placebo-controlled, cross-over, 4-week clinical trial with a 4-week washout period. Fifty hypertensive patients received 4 placebo or celery seed extract capsules (1.34 g per day) for 4 weeks as a supplement to their usual medication regimen. The blood pressure parameters were assessed using 24-h ambulatory blood pressure monitoring device. Anxiety and depression and their wide range of symptoms were evaluated using Beck anxiety and depression inventories (BAI and BDI). RESULTS In the celery treatment step, the mean reduction in BAI and BDI scores were 6.78 (P < 0.001) and 3.63 (P < 0.01), respectively. Some symptoms of anxiety including unable to relax, nervousness, numbness, dizziness, flushed face, sweating, and breathing difficulty were significantly improved by celery consumption (P < 0.001). Celery could decrease symptoms of depression such as sadness, crying, loss of energy, insomnia, irritability, fatigue, loss of interest in sex, and punishment feeling (P < 0.01). The mean reduction in blood pressure parameters was also significant during celery therapy (P < 0.001). CONCLUSIONS The psychometric properties of anxiety and depression were investigated and the results were promising. The results indicated the anti-anxiety and anti-depressive properties of celery seed extract as a supplement in hypertensive patients. CLINICAL TRIAL REGISTRATION Registry name: Iranian Registry of Clinical Trials (IRCT), Registration number: IRCT20130418013058N8, Registration link: https://www.irct.ir/trial/30021 . The study was carried out between 2018-09-21 and 2020-07-20.

[PMID: 35698811 DOI: 10.1080/00207454.2022.2089136] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2022] [Revised: 05/27/2022] [Accepted: 05/27/2022] [Indexed: 10/18/2022]
Abstract
PURPOSE OF THE STUDY The aim of this study is to evaluate the effect of apigenin on inflammatory response in brain tissue in Parkinson's mouse model. MATERIALS AND METHODS Parkinson's disease model was induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). Sixty 8-10-weeks-old male C57BL/6 mice were randomly divided into four groups control, Parkinson, prophylaxis, and treatment. Control (0.9% NaCl 0.5 ml, 10 days, i.p.), Parkinson (25 mg/kg MPTP, 5 days, i.p.), prophylaxis (50 mg/kg apigenin, 5 days + 25 mg/kg MPTP, 5 days, i.p.), and treatment (25 mg/kg MPTP, 5 days + 50 mg/kg apigenin, 5 days). The expressions and protein levels of tumor necrosis factor-alpha (TNF-α), interleukin-1-beta (IL-1β), IL-6, IL-10, and transforming growth factor-beta (TGF-β) were determined using immunohistochemistry and enzyme-linked immunosorbent analysis. RESULTS Apigenin administration attenuated MPTP-induced histopathological changes in brain tissue. Furthermore, apigenin reversed the changes in expressions and concentrations of TNF-α, IL-1β, IL-6, IL-10, and TGF-β. CONCLUSION This study suggests that apigenin could be used as a neuroprotective option to attenuate neuroinflammation in Parkinson's disease.

Abstract
The integration of nanotechnology with herbal medicines overcomes the limitations of herbal therapy and offers desirable bioactivity. Thus, this study was aimed at synthesizing Apium graveolens-gold nanoparticles (AG-AuNPs) and exploring their impact on the glucose utilization pattern of the isolated rat hemidiaphragm. The AG-AuNPs appeared in cherry red color and showed a plasmonic peak at 534nm. The bio-reduced AG-AuNPs appeared as spherical shapes with varying sizes of about 4–15 nm. It also depicted the zeta potential of -19.5 mV, face-centered cubic crystalline nature, stretching vibrations for different functionalities, and in vitro stability during various characterization studies. The AG-AuNPs showed non-cytotoxicity and promoted cellular glucose uptake on their exposure to the cell line and the diaphragm, respectively. Moreover, the identified flavonoids and polyphenols of AG depicted in silico interactions with the insulin signaling molecule. The observed results suggest that the interacting ability of AG-AuNPs with the insulin signaling molecule can promote the glucose uptake efficiency of the diaphragm.

Abstract
Natural products derived from plants, as well as their bioactive compounds, have been extensively studied in recent years for their therapeutic potential in a variety of neurodegenerative diseases (NDs), including Alzheimer's (AD), Huntington's (HD), and Parkinson's (PD) disease. These diseases are characterized by progressive dysfunction and loss of neuronal structure and function. There has been little progress in designing efficient treatments, despite impressive breakthroughs in our understanding of NDs. In the prevention and therapy of NDs, the use of natural products may provide great potential opportunities; however, many clinical issues have emerged regarding their use, primarily based on the lack of scientific support or proof of their effectiveness and patient safety. Since neurodegeneration is associated with a myriad of pathological processes, targeting multi-mechanisms of action and neuroprotection approaches that include preventing cell death and restoring the function of damaged neurons should be employed. In the treatment of NDs, including AD and PD, natural products have emerged as potential neuroprotective agents. This current review will highlight the therapeutic potential of numerous natural products and their bioactive compounds thatexert neuroprotective effects on the pathologies of NDs.

Abstract
Coronavirus disease 2019 is a worldwide pandemic resulting in a severe acute respiratory syndrome. Remdesivir is the only FDA-approved drug for hospitalized patients older than age 12. It shows the necessity of finding new therapeutic strategies. Functional foods (FFs) could have co-therapeutic and protective effects against COVID-19 infection. Traditional Persian medicine (TPM), one of the safest and most popular schools of medicine for hundreds of years, has recommended potential FF candidates to manage such a global pandemic. To reveal the potential of TPM in terms of antitussive FFs, traditional Persian pharmacopoeia "Qarabadin-e-Salehi" was searched using the keywords "Soaal" and "Sorfeh." Also, a search of MEDLINE, PubMed Central, Google Scholar, and Science Direct was performed for the relevant literature published from the inception up to March 2021. A combination of search terms including "cough, antitussive, antioxidant, anti-inflammation, antiviral, COVID-19, mucoactive, mucolytic, expectorant, and mucoregulatory" was also applied. The potential mechanism of action in SARS-CoV-2 infection was discussed. Twelve TPM FFs were found including Laooqs, Morabbas, a Saviq, a soup, and a syrup. They are combinations of two to seven ingredients. Natural compounds of mentioned formulations have the main pharmacological mechanisms including antiviral, anti-inflammatory, antioxidant, antihistamine, bronchodilator, immunomodulatory, and mucoactive effects as well as central or peripheral antitussive activities. FFs are cost-effective, easily accessible, and safe options for both treatment and prevention of COVID-19. They might have positive psychological effects along with their pharmacological effects and nutritional virtues. They could also manage persistent respiratory discomforts after recovery from COVID-19.

Abstract
Parkinson's disease (PD) occurs in approximately 1% of the population over 65 years of age and has become increasingly more common with advances in age. The number of individuals older than 60 years has been increasing in modern societies, as well as life expectancy in developing countries; therefore, PD may pose an impact on the economic, social, and health structures of these countries. Oxidative stress is highlighted as an important factor in the genesis of PD, involving several enzymes and signaling molecules in the underlying mechanisms of the disease. This review presents updated data on the involvement of oxidative stress in the disease, as well as the use of antioxidant supplements in its therapy.

Abstract
The application of chemicals in industry and agriculture has contributed to environmental pollution and exposure of living organisms to harmful factors. The development of new pharmaceutical agents enabled successful therapy of various diseases, but their administration may be connected with side effects. Oxidative stress has been found to be involved into etiology of numerous diseases as well as harmful action of drugs and chemicals. For some time, plant origin substances have been studied as potential protective agents alleviating toxicity of various substances and symptoms of diseases. The aim of the current review was to present the diversity of the research performed during the last five years on animal models. The outcomes showed a huge protective potential inherent in plant preparations, including alleviating prooxidative processes, strengthening antioxidant defence, ameliorating immune parameters, and reversing histopathological changes. In many cases, plant origin substances were proved to be comparable or even better than standard drugs. Such findings let us suggest that in the future the plant preparations could make adjuvants or a replacement for pharmaceutical agents. However, the detailed research regarding dose and way of administration as well as the per se effects needs to be performed. In many studies, the last issue was not studied, and in some cases, the deleterious effects have been observed.

Abstract
Studies indicate that mutant α-synuclein (mαSyn) is involved in the pathogenesis of Parkinson’s disease (PD). The mαSyn expression leads to the loss of dopaminergic neurons in the substantia nigra (SN) and consequent motor dysfunctions. Additionally, studies found that PD was accompanied by extensive neuroinflammation of SN. However, it remains unclear as to whether microglia participate in the mαSyn pathology. This issue is addressed by using AAV-mα-Syn (A30P-A53T) to overexpress the human mαSyn in the SN in view of establishing the PD model. Subsequently, minocycline (Mino) was used to inhibit microglia activity, and an interleukin-1 receptor (IL-1R1) antagonist was used to hinder the IL-1R1 function. Finally, immunohistochemistry was used to analyze phosphorylated αSyn (Ser129) and TH-positive cells in the SN. Dopamine levels were analyzed by high performance liquid chromatography. mαSyn overexpression in the SN induced motor dysfunction, decreased striatal dopamine levels, and increased pathological αSyn 12 weeks after AAV injection. The data demonstrated that inhibiting microglial activation or hindering IL-1R1 reversed the persistent motor deficits, neurodegeneration of the nigrostriatal dopaminergic system, and development of Lewy body pathology caused by human mαSyn overexpression in the SN. Additionally, these findings indicate that neuroinflammation promotes the loss of neuronal cells.

Abstract
Although Levodopa (l-DOPA), a dopamine precursor, exhibits a high risk of dyskinesia, it remains the primary treatment in Parkinson's disease (PD), a progressive neurodegenerative disorder. In this study, we designed poly(l-DOPA)-based self-assembled nanodrug (NanoDOPA) from amphiphilic block copolymer possessing poly(l-DOPA(OAc)2), which is a precursor of l-DOPA as a hydrophobic segment, for treatment in a PD model mouse. Under physiological enzyme treatment, the poly(l-DOPA(OAc)2) in the block copolymer was hydrolyzed to liberate l-DOPA gradually. Using the MPTP-induced PD mouse model, we observed that mice treated with NanoDOPA demonstrated a significant improvement of PD symptoms compared to the l-DOPA treatment. Interestingly, the NanoDOPA treatment did not cause the dyskinesia symptoms, which was clearly observed in the l-DOPA-treated mice. Furthermore, NanoDOPA exhibited remarkably lower toxicity in vitro compared to l-DOPA, in addition with no noticeable NanoDOPA toxicity observed in the treated mice. These results suggested that self-assembled NanoDOPA is a promising therapeutic in the treatment of PD. STATEMENT OF SIGNIFICANCE: In this study, we proposed a therapeutic approach for the effective treatment of Parkinson's disease (PD) using newly designed poly(l-DOPA)-based self-assembled nanodrug (NanoDOPA) prepared from amphiphilic block copolymers possessing poly(l-DOPA(OAc)2), which is a precursor of l-DOPA as a hydrophobic segment, for treatment in a PD model mouse. Under physiological enzyme treatments, NanoDOPA was hydrolyzed to liberate l-DOPA gradually, improving the pharmacokinetic value of l-DOPA. The mice treated with NanoDOPA significantly improved PD symptoms compared to the l-DOPA treatment in a neurotoxin-induced PD mouse model. Interestingly, NanoDOPA treatment did not cause dyskinesia symptoms, which was observed in the l-DOPA-treated mice. The obtained results in this study suggested that self-assembled NanoDOPA is a promising therapeutic in the treatment of PD.

Abstract
Although several studies have been performed on Apium graveolens L.(celery) seeds, their antiliver fibrosis effects remain to be unexplored. Firstly, we detected the effects of celery seeds extracted with different concentrations of aqueous ethanol on the proliferation of HSC-LX2 cells. Then, we detected the effects of fractions of the optimal effect extract on the proliferation and apoptosis of HSC-LX2 cells. Finally, the compounds of petroleum ether (PP), ethyl acetate (PE), n-butyl alcohol (PB), and water fractions (PW) of the optimal effect extract were determined by GC-TOF-MS and UHPLC-MS/MS, to confirm the potentially antifibrotic compounds combined with pharmacodynamic experiment of monomer compounds in vitro. The results revealed that 60% ethanol extract of celery seeds (60-extract) exhibited remarkable inhibition effect on the proliferation of HSC-LX2 cells compared with 95% ethanol and aqueous extract. Besides, it validated that the inhibition rates of PP, PE, PB, and PW on the proliferation of HSC-LX2 cells were 75.14%, 73.52%, 54.09%, and 43.36%, and their percentage of apoptotic cells were 37.5%, 4.3%, 0.7%, and 0.1% at high doses, respectively. Additionally, it was manifested that apigenin, aesculetin, and butylphthalide have major contribution to the overall compounds of celery seeds, and the inhibition effects on the cell proliferation clearly elevated with increase in their contents. In essence, apigenin, aesculetin, and butylphthalide may hopefully become the natural products of antiliver fibrosis, which laid a foundation for the subsequent development of celery seeds as antiliver fibrosis drugs.

Abstract
In recent years, natural products, which originate from plants, animals, and fungi, together with their bioactive compounds have been intensively explored and studied for their therapeutic potentials for various diseases such as cardiovascular, diabetes, hypertension, reproductive, cancer, and neurodegenerative diseases. Neurodegenerative diseases, including Alzheimer's disease, Huntington's disease, Parkinson's disease, and amyotrophic lateral sclerosis are characterized by the progressive dysfunction and loss of neuronal structure and function that resulted in the neuronal cell death. Since the multifactorial pathological mechanisms are associated with neurodegeneration, targeting multiple mechanisms of actions and neuroprotection approach, which involves preventing cell death and restoring the function to damaged neurons, could be promising strategies for the prevention and therapeutic of neurodegenerative diseases. Natural products have emerged as potential neuroprotective agents for the treatment of neurodegenerative diseases. This review focused on the therapeutic potential of natural products and their bioactive compounds to exert a neuroprotective effect on the pathologies of neurodegenerative diseases.

Abstract
Background Parkinson’s disease (PD) is a progressive neurodegenerative disorder characterized by loss of dopaminergic neurons in substantia nigra pars compacta and clinically manifested mainly with motor dysfunctions. Plants are rich source of medicinally important bioactive compounds and inhabitants of underdeveloped countries used plants for treatment of various ailments. Albizia lebbeck has been reported to possess antioxidant and neuroprotective properties that suggest the evaluation of its traditional therapeutic potential in neurodegenerative diseases. The aim of present study was to validate the traditional use of Albizia lebbeck (L.) and delineate its mechanism of action in PD. The systems pharmacology approach was employed to explain the Albizia lebbeck (L.) mechanism of action in PD. Methods The haloperidol-induced catalepsy was adopted as experimental model of PD for in-vivo studies in wistar albino rats. The systems pharmacology approach was employed to explain the Albizia lebbeck (L.) mechanism of action in PD. Results In-vivo studies revealed that Albizia lebbeck improved the motor functions and endurance as demonstrated in behavioral studies which were further supported by the rescue of endogenous antioxidant defense and reversal of ultrastructural damages in histological studies. System pharmacology approach identified 25 drug like compounds interacting with 132 targets in a bipartite graph that revealed the synergistic mechanism of action at system level. Kaemferol, phytosterol and okanin were found to be the important compounds nodes with prominent target nodes of TDP1 and MAPT. Conclusion The therapeutic efficiency of Albizia lebbeck in PD was effectively delineated in our experimental and systems pharmacology approach. Moreover, this approach further facilitates the drug discovery from Albizia lebbeck for PD.

Abstract
Apium plants belong to the Apiaceae family and are included among plants that have been in use in traditional medicine for thousands of years worldwide, including in the Mediterranean, as well as the tropical and subtropical regions of Asia and Africa. Some highlighted medical benefits include prevention of coronary and vascular diseases. Their phytochemical constituents consist of bergapten, flavonoids, glycosides, furanocoumarins, furocoumarin, limonene, psoralen, xanthotoxin, and selinene. Some of their pharmacological properties include anticancer, antioxidant, antimicrobial, antifungal, nematocidal, anti-rheumatism, antiasthma, anti-bronchitis, hepatoprotective, appetizer, anticonvulsant, antispasmodic, breast milk inducer, anti-jaundice, antihypertensive, anti-dysmenorrhea, prevention of cardiovascular diseases, and spermatogenesis induction. The present review summarizes data on ecology, botany, cultivation, habitat, medicinal use, phytochemical composition, preclinical and clinical pharmacological efficacy of Apium plants and provides future direction on how to take full advantage of Apium plants for the optimal benefit to mankind.

Abstract
OBJECTIVE To investigate the effect of acupuncture pretreatment at specific acupoints on action potential of cerebellar Purkenje cells in rats early after cerebral ischemia. METHODS Forty male SD rats were randomized into control group, ischemia group, acupuncture pretreatment group and acupuncture pretreatment plus ischemia group. The rats in acupuncture groups received acupuncture pretreatment at Baihui and bilateral Zusanli twice daily for 7 consecutive days, after which brain slices were prepared and perfused at a lowered rate to simulate in vivo ischemic stroke. Microelectrode and whole cell current clamp technique were used for recording the action potentials of cerebellar Purkenje cells to detect changes in spike encoding of the cells. RESULTS Compared with those in the control group, the rat brain slices early after simulated ischemia showed significantly shortened inter-spike intervals, increased standard deviation of spike timing and decreased voltage of threshold potentials (P<0.01), suggesting overexcitation of the Purkinje cells. Acupuncture pretreatment at Baihui and bilateral Zusanli obviously suppressed overexcitation of the Purkinje cells in response to ischemia. CONCLUSION Acupuncture pretreatment at Baihui and bilateral Zusanli can improve ischemic stroke by suppressing overexcitation of Purkenje cells in rats.
