Abstract
Background High-dose methotrexate (HDMTX) as a cytotoxic agent might cause various side effects. Hyperhydration has been implemented as the major strategy to decrease the potential risk of toxicities induced by HDMTX. This study aims to assess the renoprotective effect of hydration with dextrose water (DW) 5% versus normal saline (N/S) 0.9% against methotrexate (MTX) induced nephrotoxicity. Materials and Methods This experimental animal study has been conducted on 36 Wistar rats (200-250 g) categorized into six groups, including male (n = 6) and female (n = 6) rats receiving sodium chloride 0.9% saline plus MTX, DW 5% plus MTX, or MTX alone. By the fifth day after the MTX injection, biochemical indexes were measured. The rats were also sacrificed and renal specimens were evaluated microscopically to determine kidney tissue damage (KTD). Results The groups were not significantly different with regard to blood urea nitrogen (BUN) (P = 0.5), creatinine (Cr) (P = 0.24), kidney weight (P = 0.34), and urine flow (UF) (P = 0.5), while KTD score was remarkably less in the hydrated groups (P < 0.001). Weight loss in DW-treated rats was significantly more than N/S-treated ones, and creatinine clearance (CrCl) and urine load (UL) of Cr were statistically similar between males and females in the control group, but significantly lower among the DW5% treated males. Conclusion Based on the findings of this study, hydration with N/S was superior to DW5% for the prevention from HDMTX-induced nephrotoxicity. Besides, we found insignificant differences between male versus female rats in response to the hydration for HDMTX-induced renoprotection; however, females probably benefit more.

Abstract
Investigating long-term potentiation (LTP) in disease models provides essential mechanistic insight into synaptic dysfunction and relevant behavioral changes in many neuropsychiatric and neurological diseases. Toxoplasma (T) gondii is an intracellular parasite causing bizarre changes in host's mind including losing inherent fear of life-threatening situations. We examined hippocampal-dependent behavior as well as in vivo short- and long-term synaptic plasticity (STP and LTP) in rats with latent toxoplasmosis. Rats were infected by T. gondii cysts. Existence of REP-529 genomic sequence of the parasite in the brain was detected by RT-qPCR. Four and eight weeks after infection, spatial, and inhibitory memories of rats were assessed by Morris water maze and shuttle box tests, respectively. Eight weeks after infection, STP was assessed in dentate gyrus (DG) and CA1 by double pulse stimulation of perforant pathway and Shaffer collaterals, respectively. High frequency stimulation (HFS) was applied to induce LTP in entorhinal cortex-DG (400 Hz), and CA3-CA1 (200 Hz) synapses. T. gondii infection retarded spatial learning and memory performance at eight weeks post-infection period, whereas inhibitory memory was not changed. Unlike uninfected rats that normally showed paired-pulse depression, the infected rats developed paired-pulse facilitation, indicating an inhibitory synaptic network disruption. T. gondii-infected rats displayed strengthened LTP of both CA1-pyramidal and DG-granule cell population spikes. These data indicate that T. gondii disrupts inhibition/excitation balance and causes bizarre changes to the post-synaptic neuronal excitability, which may ultimately contribute to the abnormal behavior of the infected host.

Abstract
INTRODUCTION We have reported that thymol and carvacrol can improve cognitive abilities in Alzheimer Disease (AD) rat models. However, the mechanism of their action is not yet fully understood. Recently, our in vitro results suggested that PC12 cell death induced by Aβ25-35 can be protected by thymol and carvacrol via Protein Kinase C (PKC) and Reactive Oxygen Species (ROS) pathways. So, we hypothesize that the mechanisms of thymol and carvacrol in improving the learning impairment in the AD rat model may be related to their effects on PKC. So, the activity of PKC and protein expression levels of PKCα were examined in the hippocampal cells of the AD rat model. METHODS To examine the thymol and carvacrol effects, we performed a behavioral test in AD rat models induced by Aβ25-35 neurotoxicity. To access the underlying mechanism of the protective effects, western blotting was performed with antibodies against PKCα. We also measured the PKC activity assay by Elisa. Histopathological studies were carried out in the hippocampus with Hematoxylin and Eosin (H&E) staining. RESULTS The escape latency increased in Aβ-received rats compared to the control group, and thymol and carvacrol reversed this deficit. Furthermore, these compounds could enhance the PKC activity and increase the PKCα expression ratio. Moreover, H&E staining showed that Aβ caused shrinkage of the CA1 pyramidal neurons. However, thymol and carvacrol treatments could prevent this effect of Aβ peptides. CONCLUSION This study suggests that Amyloid-Beta (Aβ) results in memory decline and histochemical disturbances in the hippocampus. Moreover, these results revealed that thymol and carvacrol could have protective effects on cognition in AD-like models via PKC activation. HIGHLIGHTS Rat's ability to find the invisible platform in the Morris Water Maze (MWM) was impaired by Amyloid-Beta (Aβ) infusion in the hippocampus, while this effect was reversed by thymol or carvacrol administration.Aβ significantly downregulated the Protein Kinase C (PKC) activity in rats' hippocampus.Western blot analysis demonstrated that Aβ significantly reduced PKCα protein expression in AD rat model hippocampal cells.The expression ratio of PKCα was upregulated following the injection of thymol and carvacrol in rats.Injection of Aβ in the hippocampus resulted in histochemical disturbances in CA1 pyramidal neurons.Carvacrol and thymol can prevent several histological changes induced by Aβ. PLAIN LANGUAGE SUMMARY Alzheimer's disease is one of the most important brain diseases in which the learning and memory are impaired. One of the main causes of Alzheimer's disease is the presence of amyloid beta plaques in the neurons. Protein kinase C enzyme reduces amyloid production and accumulation in the brain. In the present study, we tested the possible effects of carvacrol and thymol in a rat model of Alzheimer's disease. Memory impairment was induced in adult rats by intra-cerebral infusion of amyloid β. One week later, the memory-impaired animals were treated with carvacrol and thymol. Finally, we tested their memory in a Morris water maze apparatus. Furthermore, their hippocampus was dissected and PKC activity and the neuronal injury was evaluated. Our findings exhibited that thymol and carvacrol improved rats' memory performance. In addition, thymol and carvacrol significantly increased PKC activity and prevented neuronal cell loss in the rat hippocampus. This study shows that thymol and carvacrol have beneficial effects on memory and cognitive function via PKC activation.

Abstract
Objective Neurodegenerative diseases are considered an important cause of cognitive deficit and morbidity in old ages. Alzheimer's disease (AD) is one of these disorders affecting about 40 million people in the world at the present time. Available drug therapy is mostly symptomatic and does not modify or stop disease progression. Recently, biologically active chemicals from herbs have been studied to develop new therapeutic drugs. Carvacrol has shown positive properties on many neurological diseases. This compound is expected to have the ability to affect AD pathogenesis and therefore, it is considered an anti-AD agent. Materials and Methods This review was conducted using PubMed, Google Scholar and Science Direct bibliographic databases until November 2021. For data collection, the following keywords were used: carvacrol, neuroprotective, cognition, anti-inflammatory, antioxidant, Acetylcolinesterase inhibitor (AChEI), Alzheimer's, Parkinson's, epilepsy, stroke, ischemic brain injury, and neurodegenerative diseases. Results This review summarizes in vitro and in vivo studies on protective potential of carvacrol in neurodegenerative disorders and various underlying mechanisms, such as anti-inflammatory, antioxidant, and anticholinesterase effects. Conclusion We gave an overview of available literature concerning neuroprotective effects of carvacrol in ameliorating the neurodegenerative diseases symptoms in vivo and in vitro. Particular attention is given to AD. Several neuro-pharmacological actions of carvacrol have been summarized in the current review article including anti-inflammatory, antioxidant, and AChEI properties.

Abstract
Introduction: Cisplatin (CP) is an anti-cancer drug with the most common side effects of nephrotoxicity. Losartan, an angiotensin II type 1 receptor (AT1R) antagonist and angiotensin 1-7 (Ang1-7) protects the kidney against CP administration in males Moreover, the activity of the renin angiotensin system (RAS) and the incidence of CP induced nephrotoxicity are gender related. Objectives: The role of Ang1-7 and losartan against CP induced nephrotoxicity in female rats was examined. Methods: Thirty-two female Wistar rats in five experimental groups were treated with vehicle, single dose of CP (7.5 mg/kg), CP+losartan (10 ), CP+Ang1-7 (30 μg/kg/d) or CP+Ang1-7+A779 (Mas receptor antagonist, 100 μg/kg/d). The biochemical and histology measurements were conducted one week later. Results: The levels of serum creatinine (Cr) and blood urea nitrogen (BUN) in serum increased insignificantly by CP alone administration. However co-treatment of CP with losartan, Ang1-7, or Ang1-7 plus A779 showed an increase of the serum levels of BUN and Cr, and kidney tissue damage score (KTDS) (P < 0.05) when compared with control groups. Conclusion: The AT1R and Mas receptor (MasR) antagonists and Ang1-7 administration promote the CP induced damage of kidney in female rats, and special attention is needed during CP therapy in hypertensive patients who are treating with anti-hypertensive drug of losartan.

Abstract
Several studies have reported that the host-microbe interactions in the gut modulate the host serotonin or 5-hydroxytryptamine (5-HT) system. Here, we evaluated the effects of Akkermansia muciniphila and its extracellular vesicles (EVs) on genes pertaining to the serotonergic system in the colon and hippocampus of mice. Male C57BL/6J mice were administered viable A. muciniphila and its EVs for 4 weeks. The serotonin levels in the colon, hippocampus, and serum of mice, as well as the human colon carcinoma cells (Caco-2), were measured by ELISA assays. Also, the effects of A. muciniphila and its EVs on the expression of serotonin system genes in the colon and hippocampus were examined. A. muciniphila and its EVs may have a biological effect on the induction of serotonin levels in the colon and hippocampus of mice. Also, EVs increased the serotonin level in the Caco-2 cell line. In contrast, both treatments decreased the serotonin level in the serum. Both the bacterium and its EVs had significant effects on the mRNA expression of genes, involved in serotonin signaling/metabolism in the colon and hippocampus of mice. Moreover, A. muciniphila and its EVs affected the mRNA expression of inflammatory cytokines (Il-10 and Tnf-α) in the colon, however, there is no significant difference in inflammatory cell infiltrate in the histopathology of the colon. The presence of A. muciniphila and its EVs in the gut promotes serotonin concentration, they also affect serotonin signaling/metabolism through the gut-brain axis and may be considered in new therapeutic strategies to ameliorate serotonin-related disorders.

Abstract
OBJECTIVES Modulation of sympathetic activity during acute sleep deprivation can produce various effects on body functions. We studied the effects of acute sleep deprivation before ischemia/reperfusion on myocardial injury in isolated rat hearts, and the role of sympathetic nervous system that may mediate these sleep deprivation induced effects. METHODS The animals were randomized into four groups (n = 11 per group): Ischemia- Reperfusion group (IR), Acute sleep deprivation group (SD), Control group for sleep deprivation (CON-SD) and Sympathectomy + ASD group (SYM-SD). In SD group, sleep deprivation paradigm was used 24 h prior to induction of ischemia/reperfusion. In SYM-SD group, the animals were chemically sympathectomized using 6-hydroxydopamine, 24 h before sleep deprivation. Then, the hearts of animals were perfused using Langendorff setup and were subjected to 30 min regional ischemia followed by 60 min of reperfusion. Throughout the experiment, the hearts were allowed to beat spontaneously and left ventricular developed pressure (LVDP) and rate pressure product (RPP) were recorded. At the end of study, infarct size and percentage of the area at risk were determined. RESULTS We found that SD increased LVDP and RPP, while reducing the myocardial infarct size. Moreover, sympathectomy reversed SD induced reduction in infarct size and showed no differences as compared to IR. CONCLUSION This study shows cardioprotective effects of acute sleep deprivation, which can be abolished by chemical sympathectomy in isolated hearts of rats.

Abstract
Background Fumaria species (Fumariacea) has traditionally been used in wound healing in Iranian folk medicine. However, with the discovery of newer agents, its use has faded off into total obscurity. This study explored the wound healing potential of a gel containing 10% Fumaria vaillantii Loisel through topical application of total extract in a model of excisional as well as incisional wound healing in albino Wistar rats. Methods Rats were anesthetized, and excisional skin wound was established using a sterilized surgical scissors. The animals were then treated with 10% F.vaillantii topical gel formulation along with the gel base. The treatments were administered once a day after the injury for 21 days. For topical treatment, the hydrogel was formulated and evaluated for chemical and physical characteristics. Histopathological analysis with hematoxylin and eosin (H&E) was used for microscopic examination of the skin tissues on 21-day-old sections of excision wound. To verify collagen formation, hydroxyproline determination was performed 21 days post wound healing. Breaking strength was determined in a 10-day-old incision wound by the uniaxial tensile test. Results Topical administration of F.vaillantii gel formulation significantly enhanced skin wound closure on the 6th post-wounding day compared to both gel base and the negative control, indicating an accelerated wound healing process, while a significant difference was observed on 10th and 14th post –wound days in F.vaillantii treatment compared to the negative control groups. Gel formulation prepared with a 10% F. vaillantii extract exhibited a response in terms of wound epithelialization, angiogenesis and number of hair follicles at wound area better than the gel base on the 21st post-wound day. Application of gel base produced further advantages by increasing hydroxyproline content and collagen fiber thickness. Our results on incision wound model were supported by histopathological data indicating the role of gel base in the enhancement of breaking strength. Conclusion Traditional use of Fumaria species in the skin diseases was justified in this study by revealing the increase in wound healing activity after hydrogel containing F. vaillantii total extract administration.

Abstract
Background:The concept of Epithelial-Mesenchymal Transition (EMT) to promote carcinoma progression has been recognized as a venue for research on novel anticancer drugs. Triaryl template-based structures are one of the pivotal structural features found in a number of compounds with a wide variety of biological properties including anti-breast cancer. Among the various factors triggering EMT program, cyclooxygenase-2 (COX-2), NF-κB as well as the transforming growth factor-beta (TGF-β) have been widely investigated.Objective:Here, we aim to investigate the effect of two novel compounds A and B possessing triaryl structures, which interact with both COX-2 and TGF-β active sites and suppress NF-κB activation, on EMT in a co-culture system with breast cancer and stromal cells.Methods:MDA-MB-231 and bone-marrow mesenchymal stem (BM-MS) cells were co-cultured in a trans-well plate. Migration, matrigel-based invasion and colony formation in soft agar assays along with Real- time PCR and Western blot analysis were performed to examine the effect of compounds A and B on the invasive properties of MDA-MB-231 cells after 72 hours of co-culturing with BM-MSCs. In addition, TGF-beta interaction was investigated by Localized Surface Plasmon Resonance (LSPR).Results:BM-MSCs enhanced migration, invasion and anchorage-independent growth of the co-cultured MDAMB- 231 cells. A reduction in E-cadherin level concomitant with an increase in vimentin and N-cadherin levels following the co-culture implied EMT as the underlying process. Compounds A and B inhibited invasion and anchorage-independent growth of breast cancer cells co-cultured with BM-MSCs at 10µM. The observed inhibitory effects along with an increase in E-cadherin and a reduction in vimentin and ZEB2 levels suggest that the anti-invasive properties of compounds A and B might proceed through the blockade of stromal cell-induced EMT, mediated by their interaction with TGF-beta.Conclusion:These findings introduce compounds A and B as novel promising agents, which prevent EMT in invasive breast cancer cells.

Abstract
Background: Cyclosporine (CYC) is an immunosuppressant drug used widely in kidney transplant patient. The major side effect of CYC is nephrotoxicity. In this study, three different doses of CYC alone or accompanied with zinc (Zn) supplement were administrated in male and female rats to determine the kidney tissue damages and functions.
Methods: Male and female rats were treated with 10, 50 or 100 mg/kg/day of CYC alone or accompanied with 10 mg /kg/day of Zn sulfate for 10 days. The parameters related to renal function were determined and the kidney tissues were subjected to histological evaluation.
Results: All male and female animals were treated with high dose CYC (100 mg/kg/day) alone or accompanied with Zn supplement during the experiment. The data obtained for the serum levels of creatinine (Cr) and blood urea nitrogen/Cr ratio, clearance of Cr, kidney weight (KW), sodium (Na) filtration rate, Na excretion rate and Na excretion fraction (%) in surviving animals suggest a role of gender in the variation of these factors. The kidney tissue damage score (KTDS) was increased as the dosage of CYC was elevated, and the Zn supplement attenuated the KTDS in animals treated with low dose CYC (10 mg/kg/day).
Conclusion: The CYC-induced nephrotoxicity may be gender-related, and the 10 mg/kg dose of Zn sulphate as a supplement may possibly prevent the induced nephrotoxicity in males due to its antioxidant effects.

Abstract
Epilepsy is one of the most common neurologic disorders worldwide with no distinguishable cause in 60% of patients. One-third of the world population has been infected with Toxoplasma gondii. This intracellular parasite has high tropism for excitable cells including neurons. We assessed impact of acute and chronic T. gondii infection on epileptogenesis in pentylenetetrazole (PTZ) kindling model in male rats. T. gondii cysts were administered to rats by intraperitoneal (i.p.) injection. The presence of T. gondii cysts in the brain of rats was verified by hematoxylin-eosin staining. One and eight weeks after cysts injection, as acute and chronic phases of infection, PTZ (30mg/kg, i.p.) was injected to the rats every other day until manifestation of generalized seizures. Histologic findings confirmed cerebral toxoplasmosis in rats. The rats with acute or chronic Toxoplasma infection became kindled by lower number of PTZ injections (14.8±1 and 13.6±1 injections, respectively) compared to corresponding uninfected rats (18.7±1 and 16.9±1 injections, p<0.05). Toxoplasma infection increased the rate of kindling in rats. The chronically-infected rats achieved focal and also generalized seizures earlier than the rats with acute infection. Toxoplasmosis might be considered as a risk factor for acquisition of epilepsy.

Abstract
Background Cardiovascular diseases are the leading cause of mortality and long-term
disability worldwide. Various studies have suggested a protective effect of
lactation in reducing the risk of cardiovascular diseases. Objective This study was designed to assess the effects of pregnancy and lactation on
the vulnerability of the myocardium to an ischemic insult. Methods Eighteen female rats were randomly divided into three groups:
ischemia-reperfusion (IR), in which the hearts of virgin rats underwent IR
(n = 6); lactating, in which the rats nursed their pups for 3 weeks and the
maternal hearts were then submitted to IR (n = 6); and non-lactating, in
which the pups were separated after birth and the maternal hearts were
submitted to IR (n = 6). Outcome measures included heart rate (HR), left
ventricular developed pressure (LVDP), rate pressure product (RPP), ratio of
the infarct size to the area at risk (IS/AAR %), and ventricular arrhythmias
- premature ventricular contraction (PVC) and ventricular tachycardia
(VT). Results The IS/AAR was markedly decreased in the lactating group when compared with
the non-lactating group (13.2 ± 2.5 versus 39.7
± 3.5, p < 0.001) and the IR group (13.2 ± 2.5
versus 34.0 ± 4.7, p < 0.05). The evaluation
of IR-induced ventricular arrhythmias indicated that the number of compound
PVCs during ischemia, and the number and duration of VTs during ischemia and
in the first 5 minutes of reperfusion in the non-lactating group were
significantly (p < 0.05) higher than those in the lactating and IR
groups. Conclusion Lactation induced early-onset cardioprotective effects, while rats that were
not allowed to nurse their pups were more susceptible to myocardial IR
injury.

Abstract
OBJECTIVES Traumatic brain injury (TBI) is a well-known cause of symptomatic epilepsy. In animal models of post-traumatic epilepsy (PTE), progression of trauma to epilepsy takes several weeks to months. Although this long process is similar to clinical PTE, it is costly and laborious. We used a combination of TBI and kindling as an accelerated animal model to develop epilepsy in much shorter period compared to that occurring in PTE. METHODS Traumatic brain injury was exerted to parieto-temporal cortex of anaesthetised rats by controlled cortical impact (CCI, 5 mm round tip, 4.5 mm/seconds velocity and 150 ms duration). Chemical kindling started 24 hours after CCI by intraperitoneal injection of 30 mg/kg pentylenetetrazole (PTZ) every other day until manifestation of three consecutive generalised seizures. Rapid electrical kindling of the amygdala began 1 week after TBI by exertion of 12 daily threshold stimuli (50 Hz mono-phasic square-wave stimulus of 1 ms per wave for 3 seconds) with 5 minutes interval between each stimulation until the rats became kindled. RESULTS Controlled cortical impact injury accelerated rate of both chemical and electrical kindling. Number of PTZ injections required for acquisition of generalised seizures decreased from 13.1 ± 1.6 in sham-operated animals to 7.1 ± 0.3 in traumatic rats (p < 0.05). The required number of stimuli to elicit electrically kindled focal and generalised seizures decreased from 24.0 ± 3.9 and 80 ± 6.5 in sham-operated animals to 6.6 ± 0.9 and 53 ± 6.5 in traumatic rats (p < 0.01), respectively. LIMITATIONS Unlike the animal models of PTE in which recurrent seizures occur spontaneously after TBI, in our study, epilepsy is elicited by kindling stimulations. DISCUSSION Traumatic brain injury facilitates acquisition of epilepsy in both chemical and electrical kindling models. Combination of trauma and kindling can be considered as an inexpensive and time-saving animal model in PTE studies.

Abstract
INTRODUCTION Memory and cognitive impairments are some of devastating outcomes of Multiple Sclerosis (MS) plaques in hippocampus, the gray matter part of the brain. The present study aimed to evaluate the intrahippocampal injection of Ethidium Bromide (EB) as a simple and focal model to assess cognition and gray matter demyelination. METHODS Thirty Wistar rats were divided into three groups: control group, which received saline, as solvent of EB, into the hippocampus; and two experimental groups, which received 3 μL of EB into the hippocampus, and then, were evaluated 7 and 28 days after EB injection (n=10 in each group), using a 5-day protocol of Morris Water Maze (MWM) task as well as Transmission Electron Microscopy (TEM) assay. RESULTS Seven days after EB injection, the behavioral study revealed a significance increase in travelled distance for platform finding in the experimental group compared to the control group. In addition, the nucleus of oligodendrocyte showed the typical clumped chromatin, probably attributed to apoptosis, and the myelin sheaths of some axons were unwrapped and disintegrated. Twenty-eight days after EB injection, the traveled distance and the time spent in target quadrant significantly decreased and increased, respectively in experimental groups compared to the control group. Also, TEM micrographs revealed a thin layer of remyelination around the axons in 28 days lesion group. DISCUSSION While intracerebral or intraventricular injection of EB is disseminated in different parts of the brain and can affect the other motor and sensory systems, this model is confined locally and facilitates behavioral study. Also, this project could show improvement of memory function subsequent to the physiological repair of the gray matter of the hippocampus.

Abstract
Melissa officinalis L. (Labiatae) traditionally used in treating neurological disorders has also been identified as a memory-enhancing herb. The extract of M. officinalis has a cholinergic property. The role of basal forebrain cholinergic neurons, the neurons that are destroyed in Alzheimer's disease (AD), in learning and memory, is also well known. The aim of this study is to investigate the role of cholinergic system on the memory improving activity of M. officinalis extract. The leaves of M. officinalis were extracted with ethanol 80% using the maceration method. Rats received intra-peritoneal injections of M. officinalis extract in different doses (50-400 mg/kg) alone or in combination with scopolamine (1 mg/kg) before being trained in a Morris water maze (MWM) in a single-day training protocol. After training, the acetylcholinesterase enzyme (AChE) activity was measured in the hippocampus. Administration of M. officinalis extract (200 mg/kg) could significantly enhance learning and memory of naïve rats (p<0.001) and significantly ameliorate scopolamine-induced learning deficit, but the effect of the extract was not dose dependent, and doses above 200 mg/kg could neither enhance memory in naïve rats nor reverse scopolamine-induced memory impairment. Also, inhibition of AChE activity was observed in both naïve and scopolamine-induced memory-impaired rats. These results suggest that M. officinalis can improve memory and that the cholinergic property of the extract may contribute to the memory-improving effects observed in this study. Then M. officinalis extract has potential therapeutic value in alleviating certain memory impairment observed in AD.

Abstract
Parkinson's disease (PD) patients vary widely in their response to levodopa treatment, and this may be partially genetic in origin. Recent studies suggest that catechol-O-methyltransferase (COMT), G1947A and monoamine oxidase B (MAOB), A644G polymorphisms might influence the risk and treatment of PD. Herein, we aimed to test the possible influence of MAOB and COMT genetic polymorphisms on the effective daily dose of levodopa administered in the fifth year of treatment. We also examined the effect of COMT and MAOB haplotypes on levodopa therapy outcome. There were 31 females and 72 males of Iranian origin diagnosed with sporadic PD included into the study. The patients were divided into two groups. Group 1: patients received daily doses of levodopa below 500 mg in the fifth year of treatment. Group 2: those patients receiving daily doses exceeding 500 mg in the fifth year of treatment. MAOB and COMT polymorphism genotyping was performed by using PCR-based restriction fragment length polymorphism (RFLP) analyses. Our data show that the first group suffered less frequently from dyskinesia than patients from the second group. No statistically significant differences were found in allele frequencies and genotype distributions of the studied genes between two groups. In addition, the incidence of the specific haplotypes between the two groups did not show any difference. The present data suggest that pharmacokinetic or pharmacodynamic factors other than the investigated genetic variants of the MAOB and COMT enzymes seem to determine the response to levodopa in the Iranian PD patients.

Abstract
BACKGROUND Gap junctions composed of connexins (Cx) are functional in cell defense by propagation of toxic/death molecules to neighboring cells. Hippocampus, one of the brain regions with particular vulnerability to damage, has a wide network of gap junctions. Functional response of astrocytic Cx30 and neuronal Cx32 to hippocampal damage is unknown. METHODS We infused lipopolysaccharide (LPS) intracerebroventricularly (2.5 mug/rat) once daily for two weeks to create neuroinflammation. The mRNA and protein levels of the Cx were measured in the hippocampus after 1st, 7th and 14th injection by real-time PCR and Western-blot techniques. RESULTS A significant increase in Cx32 and Cx30 gene expression was observed after 7th and 14th injection of LPS with no significant change in their protein abundance. CONCLUSION Transcriptional overexpression of hippocampal Cx30 and Cx32 could be an adaptive response to production of intracellular toxic molecules but it is not accompanied with post- transcriptional overexpression and might have no functional impact.

Abstract
OBJECTIVE The spice Zingiber officinale or ginger possesses antioxidant activity and neuroprotective effects. The effects of this traditional herbal medicine on 3,4-methylenedioxymethamphetamine (MDMA) induced neurotoxicity have not yet been studied. The present study considers the effects of Zingiber officinale on MDMA-induced spatial memory impairment and apoptosis in the hippocampus of male rats. MATERIALS AND METHODS In this experimental study, 21 adult male Sprague Dawley rats (200-250 g) were classified into three groups (control, MDMA, and MDMA plus ginger). The groups were intraperitoneally administered 10 mg/kg MDMA, 10 mg/kg MDMA plus 100 mg/kg ginger extract, or 1 cc/kg normal saline as the control solution for one week (n=7 per group). Learning memory was assessed by Morris water maze (MWM) after the last administration. Finally, the brains were removed to study the cell number in the cornu ammonis (CA1) hippocampus by light microscope, Bcl-2 by immunoblotting, and Bax expression by reverse transcription polymerase chain reaction (RT-PCR). Data was analyzed using SPSS 16 software and a one-way ANOVA test. RESULTS Escape latency and traveled distances decreased significantly in the MDMA plus ginger group relative to the MDMA group (p<0.001). Cell number increased in the MDMA plus ginger group in comparison to the MDMA group. Down-regulation of Bcl-2 and up-regulation of Bax were observed in the MDMA plus ginger group in comparison to the MDMA group (p<0.05). CONCLUSION Our findings suggest that ginger consumption may lead to an improvement of MDMA-induced neurotoxicity.

Abstract
BACKGROUND Hippocampal damages, which are accompanied by inflammation, are among the main causes of epilepsy acquisition. We previously reported that chronic intracerebroventricular (i.c.v.) injection of lipopolysaccharide (LPS) modulates epileptogenesis in rats. There is a network of gap junction channels in the hippocampus that contribute to epileptogenesis. Gap junction channels are formed by oligomeric protein subunits called connexins (Cx). Astrocytic Cx43 and neuronal Cx36 are expressed in the hippocampus. In order to find out the possible role of gap junctions in seizure-modulating effect of LPS and neuroinflammation, we studied the effect of central administration of LPS on expression of Cx36 and Cx43 in rat hippocampus. METHODS LPS, 2.5 mug/rat/day, was injected i.c.v. to male Wistar rats for 14 days. mRNA and protein abundance of Cx36, Cx43 and IL1-β were measured in rat hippocampus by real time-PCR, Western blot and ELISA techniques, at the beginning, in the middle, and at the end of the treatment period. RESULTS IL1-β protein level was significantly increased 6 h after first injection of LPS. Cx36 and Cx43 mRNA expression did not alter during chronic administration of LPS. A selective decrease in Cx43 protein expression was observed after 7 injections of LPS. CONCLUSION It is suggested that Cx43 containing gap junctions in the hippocampus is down-regulated in response to chronic injection of LPS. This event can inhibit propagation of toxic and noxious molecules to neighboring cells and modulate hippocampal excitability and epileptogenesis.

Abstract
INTRODUCTION The limitations of current Alzheimer's disease (AD) therapeutics have prompted investigation into innovative therapeutics focused on antiinflammatory, antioxidant, and neuroprotective agents including those from medicinal plants. Numerous plants have been tested for their potential for alleviating symptoms of AD. AIMS Zataria multiflora Boiss. (ZM) a member of Lamiaceae family has been used in Iranian traditional medicine for its beneficial effects on mental abilities. Therefore, the effect of its essential oil was evaluated in a rat model of AD. METHODS Amyloid β-protein (Aβ) fragment 25-35 was injected bilaterally in the CA1 region of rats hippocampus and the effect of different doses of ZM essential oil (50, 100, or 200 μL/kg) on cognitive function was investigated in the Morris water maze. Acute toxicity of the essential oil was also studied. RESULTS The results showed increases in escape latency, traveled distance, heading angle, and decreases in target quadrant entries in Aβ-received groups as compared to the control group. This impairment was reversed by ZM essential oil. The results of acute toxicity testing revealed that the calculated LD50 (1264.9 μL/kg) is much higher than the therapeutic dose (100 μL/kg). CONCLUSIONS It seems that antioxidant, antiinflammatory, and anticholinesterase activities of ZM or its main constituents might contribute to its beneficial effects in this model. Our findings suggest that ZM may be a potentially valuable source of natural therapeutic agents for the treatment of AD. However, further investigations are necessary to establish its clinical efficacy and potential toxicity, before any recommendations concerning its use as a medication in the treatment of AD.

Abstract
Neuroinflammation is associated with a number of neurodegenerative diseases. It is known that lipopolysaccharide (LPS) treatment induces neuroinflammation and memory deterioration. Agmatine, the metabolite of arginine by arginine decarboxylase, is suggested to be a neuroprotective agent. The aim of this study was to explore if agmatine can prevent LPS-induced spatial memory impairment and hippocampal apoptosis. Adult male Wistar rats (200-250 g) were trained in water maze for 4 days (3 days in hidden platform and the last day in visible platform task). Saline, LPS (250 microg/kg/ip) or (and) agmatine (5 or 10 mg/kg) were administered 4h before every training session. LPS treatment impaired water maze place learning while agmatine co-administration prevented it. Also western blot studies revealed that LPS induces hippocampal caspase-3 activation while agmatine treatment prevented it.

Abstract
Although brain was considered as an insulin-insensitive organ, recently it has appeared that insulin has some interesting effects on some brain regions like hippocampus. It has been known that intra-hippocampally administered insulin can improve learning and memory. Knowing that insulin can stimulate nitric oxide (NO) synthesis via eNOS activation and also that NO synthase (NOS) inhibitors can affect learning and memory, the aim of this study was to assess if NO is involved in insulin induced memory improvement. Wistar male rats were intra-CA1 cannulated and the effect of post-training and pre-probe trial intra-hippocampal administration of N-nitro-L-arginine methyl ester (L-NAME) (5, 10, 30 microg), insulin+L-NAME+/-L-arginine were assessed in a single-day testing version of Morris water maze (MWM) task. Our results show that, l-NAME can prevent insulin induced memory improvement. This drug had no effect on escape latency of a non-spatial visual discrimination task. Therefore, it seems that endogenous nitric oxide has a role in spatial learning and memory improvement caused by insulin.

Abstract
Although the brain was considered as an insulin-insensitive organ, recent studies have shown that insulin receptors exist in the brain and insulin modulates some of the brain tasks. Insulin and its receptor are found in specific areas of CNS with a variety of region-specific functions different from its direct glucose regulation in the periphery. The hippocampus and cerebral cortex distributed insulin/insulin receptor has been shown to be involved in brain cognitive functions. The improving effect of insulin on spatial memory acquisition has been shown. In the present study, the effect of insulin microinjection into the CA1 region of rat hippocampus on spatial memory consolidation and retrieval has been investigated. Insulin in 12 MU (but not in 0.5 and 6 MU) improved both memory retrieval and consolidation.
