Omega-3 fatty acids supplementation prevents learning and memory impairment induced by chronic ethanol consumption in adolescent male rats through restoration of inflammatory and oxidative responses. Int J Dev Neurosci 2024. [PMID: 38803108 DOI: 10.1002/jdn.10336] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Revised: 04/03/2024] [Accepted: 04/24/2024] [Indexed: 05/29/2024] Open
Abstract
OBJECTIVE Ethanol (Eth) intake is known to cause numerous detrimental effects on the structure and function of the brain, and it is commonly used as a psychostimulant drug by adolescents. Conversely, omega-3 (O3) can reduce the risk of cognitive decline and promote the maintenance of neurophysiological functions. In this study, we investigated the protective effects of O3 on behavioral alterations, oxidative stress, and interleukin-6 (IL-6) levels induced by chronic Eth intake during adolescence in rats. MATERIALS AND METHODS Adolescent male rats (21 days old) were divided as follows: (1) Vehicle, (2) Eth (Eth in drinking water [20%]), (3-5) Eth + O3 (50/100/150 mg/kg), and (6) O3 (150 mg/kg). After 5 weeks, Morris water maze (MWM) and passive avoidance (PA) tests were performed, and the hippocampal and cortical levels of oxidative stress markers and inflammatory indices were measured. RESULTS Adolescent Eth intake impairs learning and memory function in MWM and PA tests (groups × day, p < 0.05 and p < 0.001, respectively). It was shown that Eth induced oxidative stress and neuroinflammation. O3 improved learning and impairment induced by Eth by reducing the adverse effects of Eth on the oxidant/antioxidant balance in the hippocampi (for malondialdehyde [MDA]/thiol: p < 0.01, p < 0.001, respectively) and for superoxide dismutase (SOD)/catalase (CAT): p < 0.01 and p < 0.05, respectively). Furthermore, we found that O3 prevented the Eth-induced increase of hippocampal IL-6 (p < 0.001). CONCLUSION O3 supplementation acts as an effective approach to prevent learning and memory impairments induced by chronic Eth consumption during adolescence. In this respect, the antioxidant and anti-inflammatory properties of O3 seem to be the main underlying mechanisms of neuroprotection.

Abstract
RATIONALE Tramadol and ethanol, as psychoactive agents, are often abused. Discovering the molecular pathways of drug-induced memory creation may contribute to preventing drug addiction and relapse. OBJECTIVE The tramadol- and ethanol-induced state-dependent memory (SDM) and cross-SDM retrieval between tramadol and ethanol were examined in this study. Moreover, because of the confirmed involvement of GABAA receptors and GABAergic neurotransmission in memory retrieval impairment, we assessed cross-SDM retrieval between tramadol and ethanol with a specific emphasis on the role of the GABAA receptors. The first hypothesis of this study was the presence of cross-SDM between tramadol and ethanol, and the second hypothesis was related to possible role of GABAA receptors in memory retrieval impairment within the dorsal hippocampus. The cannulae were inserted into the hippocampal CA1 area of NMRI mice, and a step-down inhibitory avoidance test was used to evaluate state dependence and memory recovery. RESULTS The post-training and/or pre-test administration of tramadol (2.5 and 5 mg/kg, i.p.) and/or ethanol (0.5 and 1 g/kg, i.p.) induced amnesia, which was restored after the administration of the drugs 24 h later during the pre-test period, proposing ethanol and tramadol SDM. The pre-test injection of ethanol (0.25 and 0.5 g/kg, i.p.) with tramadol at an ineffective dose (1.25 mg/kg) enhanced tramadol SDM. Moreover, tramadol injection (1.25 and 2.5 mg/kg) with ethanol at the ineffective dose (0.25 g/kg) promoted ethanol SDM. Furthermore, the pre-test intra-CA1 injection of bicuculline (0.0625, 0.125, and 0.25 μg/mouse), a GABAA receptor antagonist, 5 min before the injection of tramadol (5 mg/kg) or ethanol (1 g/kg) inhibited tramadol- and ethanol-induced SDM dose-dependently. CONCLUSION The findings strongly confirmed cross-SDM between tramadol and ethanol and the critical role of dorsal hippocampal GABAA receptors in the cross-SDM between tramadol and ethanol.

Omega-3 fatty acids prevent nicotine withdrawal-induced impairment of learning and memory via affecting oxidative status, inflammatory response, cholinergic activity, BDNF and amyloid-B in rat hippocampal tissues. Life Sci 2023; 332:122100. [PMID: 37722588 DOI: 10.1016/j.lfs.2023.122100] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2023] [Revised: 08/29/2023] [Accepted: 09/15/2023] [Indexed: 09/20/2023]
Abstract
In the present study, the main objective was to reveal whether treatment by Omega-3 fatty acids could prevent the adverse effects of adolescent nicotine withdrawal on spatial and avoidance memory in male rats. For this purpose, Morris water maze and passive avoidance tests were performed on male Wistar rats and the hippocampal levels of oxidative stress markers, inflammatory indices, brain-derived neurotrophic factor, nitrite, amyloid-B and acetylcholinesterase (AChE) were measured. Moreover, density of dark neurons were assessed in CA1 and CA3 regions. Results showed that adolescent nicotine exposure followed by a period of drug cessation exacerbates the behavioral indices of learning and memory through affecting a variety of biochemical markers within the hippocampal tissues. These changes lead to elevation of oxidative and inflammatory markers, reduction of neurotrophic capacity and increased AChE activity in hippocampal tissues. In addition, it was observed that co-administration of nicotine with Omega-3 fatty acids significantly prevents nicotine withdrawal-induced adverse effects through restoration of the mentioned biochemical disturbances. Therefore, we suggest administration of Omega-3 fatty acids as a safe, inexpensive and effective therapeutic strategy for prevention of memory dysfunctions associated with nicotine abstinence during adolescence.

Behav Brain Res 2023; 438:114156.

Abstract
There are growing evidence indicating that the adolescent brain is persistently affected by the use of psychostimulant agents. In this regard, alcohol drinking has become rather common among the adolescents in many societies during the last decade. It is currently well known that long-term ethanol exposure deteriorates various cognitive functions such as learning and memory. Mechanistically, these adverse effects have been shown to be mediated by oxidative damage to central nervous system. On the other hand, Vit-B12 is known to improve cognitive performance by suppression of oxidative parameters. Thus, in the present study we aimed to test whether treatment by Vit-B12 could prevent ethanol-induced complications in mice using behavioral and biochemical methods. Different groups of male Syrian mice received ethanol, ethanol+Vit-B12, Vit-B12 alone, or saline during adolescence and then learning and memory functions were assessed by Morris water maze (MWM) and Passive Avoidance (PA) tests. Finally, mice were sacrificed for measurement of biochemical factors. Results indicated that, adolescent ethanol intake impairs learning and memory function through exacerbation of oxidative stress and Vit-B12 treatment improves these complications by re-establishment of oxidant/anti-oxidant balance in CNS. Moreover, we found that Vit-B12 prevents ethanol-induced reduction of BDNF and enhancement of GFAP and acetylcholinesterase (AChE) activity. In conclusion, it seems that Vit-B12 supplementation could be used as an effective therapeutic strategy to prevent learning and memory defects induced by chronic alcohol intake during adolescence.

SAGE Open Med 2022; 10:20503121221105330. [PMID: 35769490 PMCID: PMC9235302 DOI: 10.1177/20503121221105330] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2021] [Accepted: 05/16/2022] [Indexed: 12/02/2022] Open
Abstract
Objectives: Lead exposure has destructive effects on some organs. It may
produce a variety of toxic effects on endothelial cells of the
vascular system. Any changes or damages to endothelial cells may
lead to cardiovascular diseases, particularly the formation of
atherosclerotic plaques. The aim of this study was to determine
the ameliorative effects of ascorbic acid on the endothelium of
coronary and aorta arteries in lead-exposed rabbits. Methods: In this study, 30 white male rabbits of New Zealand race (weighing
about 1.6–2 kg and 5 months old) were used and divided randomly
into three groups: Group 1 (N = 10) that served
as the control and received water and normal diet, Group 2
(N = 10) was exposed to lead acetate
547 ppm (5 mg/L) daily for 40 days, and Group 3
(N = 10) received vitamin C (500 mg/kg)
and underwent the same duration of lead exposure (5 mg/L) daily
for 40 days. The levels of cholesterol, triglyceride,
low-density lipoprotein, and high-density lipoprotein were
measured using spectrophotometry, and the level of blood lead
was calculated using a lead analyzer (Magellan Diagnostics,
USA). The animals were anesthetized by pentobarbital (50 mg/kg).
Subsequently, they were sacrificed, and their thoracic aortas
and coronary arteries were removed. Then fixation, tissue
processing, histological sectioning, and H & E staining were
carried out. Finally, the sections were studied using light
microscopy. The results were analyzed using the Mann–Whitney
test. Results: The results indicated that ascorbic acid could reduce the
destructive effects of lead on vascular endothelial cells and
prevent the formation of atherosclerotic plaques in coronary and
aorta arteries. Conclusion: The results of this study confirm the beneficial effects of
ascorbic acid against the destructive effects of lead on
vascular endothelial cells. Hence, it could be proposed as a
potential prophylactic treatment for the amelioration of lead
toxicity, prevention of atherosclerosis, and improvement of
endothelial cells dysfunction.

Combination Treatment of Omega-3 Fatty Acids and Vitamin C Exhibited Promising Therapeutic Effect against Oxidative Impairment of the Liver in Methotrexate-Intoxicated Mice. BIOMED RESEARCH INTERNATIONAL 2022; 2022:4122166. [PMID: 35496049 PMCID: PMC9045995 DOI: 10.1155/2022/4122166] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/30/2022] [Revised: 03/29/2022] [Accepted: 04/05/2022] [Indexed: 02/07/2023]
Abstract
Drug-induced liver injury (DILI) is the main cause of liver damage mediated by the excretion of toxic active drug metabolites. Omega-3 fatty acids and vitamin C have potent antioxidant, anti-inflammatory, and antiapoptotic effects that could offer protection against oxidative stress and liver damage. This study evaluated the hepatoprotective effect of omega-3 and vitamin C alone as well as in a combined form in methotrexate- (MTX-) induced acute liver injury in mice. Male ICR mice of seven groups (7 mice per group) were used. Groups 1 (control group) and 2 (MTX) received 0.9% saline/day (po) for 9 days. Groups 3 and 4 received 100 and 200 mg/kg bw/day omega-3 (po), respectively, for 9 days. Groups 5 and 6 received 100 and 200 mg/kg bw/day vitamin C (po), respectively, for 9 days, while group 7 received omega-3 (100 mg/kg bw/day) and vitamin C (100 mg/kg bw/day) (po) for 9 days. All animals in groups 2 to 7 received 20 mg/kg/day MTX (I.P.) once on the 10th day. Our results revealed that MTX significantly induced the elevation of transaminases, alkaline phosphates (ALP), lactate dehydrogenase (LDH), and malonaldehyde (MDA) while depleting the levels of superoxide dismutase (SOD) and glutathione (GSH) when compared to the control group. Treatment with omega-3 fatty acids or vitamin C significantly attenuated the antioxidants and biochemical alterations in a dose-independent manner. Our molecular docking study of ligand-receptor interaction revealed that both ascorbic acid and omega-3 docked well to the binding cavity of LDH with high binding affinities of –5.20 and –4.50 kcal/mol, respectively. The histopathological features were also improved by treatment with omega-3 and vitamin C. The combined form of omega-3 and vitamin C showed a remarkable improvement in the liver enzymes, oxidative stress biomarkers, and the histopathological architecture of the mice. Conclusively, the combination of omega-3 and vitamin C demonstrated a synergistic therapeutic effect against MTX-intoxicated mice, hence representing a potential novel strategy for the management of drug-induced liver disorders.

Abstract
Lead (Pb) is a heavy metal commonly found in the environment and is known to have neurotoxic, hematological, and other toxic effects. It has been reported that Pb exposure can disturb metal regulation in the blood-cerebrospinal fluid-barrier (BCB). Copper (Cu) plays a key role in maintaining normal brain function and can accumulate in the brain after Pb exposure. However, the mechanism by which Pb affects Cu levels in the brain is still unknown. This study investigated Cu clearance by the BCB in the central nervous system (CNS) of Sprague-Dawley rats after Pb exposure by focusing on the Cu transporter protein CTR1/ATP7A. Inductively coupled plasma mass spectrometry (ICP-MS) was used to examine how heavy metal levels change in the hippocampus, cortex, and cerebrospinal fluid (CSF) after Pb exposure. Ventriculo-cisternal perfusion measurements suggested that the ability of the BCB to deliver Cu from the CSF to the blood decreased after Pb exposure. The presence of excess Cu in the choroid plexus led to CTR1/ATP7A shifting toward the apical microvilli facing the CSF after Pb exposure. We further evaluated microstructure of the choroid plexus by transmission electron microscopy, revealing altered mitochondrial morphology with decreased microvilli after Pb exposure. Conclusively, exposure to Pb alters the cellular structure of the BCB and its Cu clearance function, which can cause further brain damage.

Abstract
Spectral power density (SPD) indexed by electroencephalogram (EEG) recordings has recently gained attention in elucidating neural mechanisms of chronic pain syndromes and medication use. We compared SPD variations between 15 fibromyalgia (FM) women in use of opioid in the last three months (73.33% used tramadol) with 32 non-users. EEG data were obtained with Eyes Open (EO) and Eyes Closed (EC) resting state. SPD peak amplitudes between EO-EC were smaller in opioid users in central theta, central beta, and parietal beta, and at parietal delta. However, these variations were positive for opioid users. Multivariate analyses of variance (ANOVAs) revealed that EO-EC variations in parietal delta were negatively correlated with the disability due to pain, and central and parietal beta activity variations were positively correlated with worse sleep quality. These clinical variables explained from 12.5 to 17.2% of SPD variance. In addition, central beta showed 67% sensitivity / 72% specificity and parietal beta showed 73% sensitivity/62% specificity in discriminating opioid users from non-users. These findings suggest oscillations in EEG might be a sensitive surrogate marker to screen FM opioid users and a promising tool to understand the effects of opioid use and how these effects relate to functional and sleep-related symptoms.

Effects of chronic tramadol administration on cognitive flexibility in mice. Psychopharmacology (Berl) 2021; 238:2883-2893.

Abstract
RATIONALE Tramadol is widely used for pain relief especially in seniors. However, long-term use of tramadol has serious adverse effects, including cognitive impairment. Besides its memory effects, already demonstrated in animals, a recent clinical report suggests that tramadol could also affect executive function in seniors. Several studies have hypothesized that the anti-muscarinic properties of tramadol could be responsible for the deleterious effects of tramadol on cognition. OBJECTIVES We aimed at investigating the effects of chronic administration of tramadol on cognitive flexibility in adult male mice, as assessed by a visual discrimination reversal task using a touchscreen device. The effects of tramadol were further compared to those of scopolamine, a reference muscarinic antagonist. RESULTS We found that, during the early phase of the reversal task, when cognitive flexibility is most in demand, both tramadol-treated mice (20 mg/kg, s.c., twice a day) and scopolamine-treated mice (0.5 mg/kg, s.c., twice a day) needed more correction trials and showed a higher perseveration index than saline-treated mice. Therefore, tramadol affects cognitive flexibility, and its anticholinergic properties could be at least partly involved in these deficits. CONCLUSIONS In view of these deleterious cognitive effects of tramadol, physicians should be cautious when prescribing this analgesic, especially in seniors who are more vulnerable to adverse drug events and in which alternative prescription should be preferred whenever possible.

Boldenone undecylenate disrupts the immune system and induces autoimmune clinical hypothyroidism in rats: Vitamin C ameliorative effects. Int Immunopharmacol 2021; 99:107939. [PMID: 34224995 DOI: 10.1016/j.intimp.2021.107939] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2021] [Revised: 06/07/2021] [Accepted: 06/28/2021] [Indexed: 12/20/2022]
Abstract
The present study was designed to evaluate the effects of boldenone undecylenate (BL) abuse alone and in combination with vitamin C (VC) on the immune responses and thyroid structure and function in rats. Thirty adult male Wistar rats were randomly divided into five equal groups and were subjected to various treatment regimens for eight weeks as follows: control group, vehicle control group, VC group orally received VC (120 mg/Kg BW/day), BL-treated group intramuscularly injected with BL (5 mg/kg BW, once/week), and BL+VC group received BL and VC. At the end of this experiment, blood and tissue samples (thyroid, thymus, and spleen) were subjected to hematological evaluation, biochemical analysis, histopathological, and immunohistochemical examinations. In comparison to controls, BL significantly increased the levels of serum proinflammatory interleukins (IL-1 β and IL-6), immunoglobulins (IgG and IgM), and complement 3 but reduced anti-inflammatory interleukin-10, lysosome, and nitric oxide. Besides, altered platelet count and leukogram were evident in BL-injected rats. BL notably disturbed thyroid profile as revealed by a significant increase of thyroid-stimulating hormone and thyroid peroxidase antibody. In contrast, both total and free forms of thyroid hormones (tri-iodothyronine and thyroxine), thyroglobulin, and thyroid peroxidase, were significantly decreased. Moreover, BL caused histopathological changes in the thyroid, thymus, and spleen tissues.CD4+ immuno-expression was reduced, but CD8+ immunolabelling was increased in both spleen and thymus. The daily dosing of VC to BL-exposed rats significantly corrected most of the deviations in immune parameters. It restored most of the thyroid architecture and function, revealing a significant protective effect of this vitamin. This experimental study demonstrates that BL abusing disrupts the immune system by different mechanisms and addresses BL, for the first time, as an autoimmune clinical hypothyroidism inducer drug. Additionally, VC is helpful in the management of BL abuse.

Modulation of vigabatrin induced cerebellar injury: the role of caspase-3 and RIPK1/RIPK3-regulated cell death pathways. J Mol Histol 2021; 52:781-798. [PMID: 34046766 DOI: 10.1007/s10735-021-09984-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2021] [Accepted: 05/24/2021] [Indexed: 01/11/2023]
Abstract
Vigabatrin is the drug of choice in resistant epilepsy and infantile spasms. Ataxia, tremors, and abnormal gait have been frequently reported following its use indicating cerebellar involvement. This study aimed, for the first time, to investigate the involvement of necroptosis and apoptosis in the VG-induced cerebellar cell loss and the possible protective role of combined omega-3 and vitamin B12 supplementation. Fifty Sprague-Dawley adult male rats (160-200 g) were divided into equal five groups: the control group received normal saline, VG200 and VG400 groups received VG (200 mg or 400 mg/kg, respectively), VG200 + OB and VG400 + OB groups received combined VG (200 mg or 400 mg/kg, respectively), vitamin B12 (1 mg/kg), and omega-3 (1 g/kg). All medications were given daily by gavage for four weeks. Histopathological changes were examined in H&E and luxol fast blue (LFB) stained sections. Immunohistochemical staining for caspase-3 and receptor-interacting serine/threonine-protein kinase-1 (RIPK1) as well as quantitative real-time polymerase chain reaction (qRT-PCR) for myelin basic protein (MBP), caspase-3, and receptor-interacting serine/threonine-protein kinase-3 (RIPK3) genes were performed. VG caused a decrease in the granular layer thickness and Purkinje cell number, vacuolations, demyelination, suppression of MBP gene expression, and induction of caspases-3, RIPK1, and RIPK3 in a dose-related manner. Combined supplementation with B12 and omega-3 improved the cerebellar histology, increased MBP, and decreased apoptotic and necroptotic markers. In conclusion, VG-induced neuronal cell loss is dose-dependent and related to both apoptosis and necroptosis. This could either be ameliorated (in low-dose VG) or reduced (in high-dose VG) by combined supplementation with B12 and omega-3.

Boldenone Undecylenate-Mediated Hepatorenal Impairment by Oxidative Damage and Dysregulation of Heat Shock Protein 90 and Androgen Receptors Expressions: Vitamin C Preventive Role. Front Pharmacol 2021; 12:651497.

Abstract
Boldenone Undecylenate (BLD) is a synthetic derivative of testosterone and a widely used anabolic androgenic steroid. The health risk of BLD use as a pharmaceutical or dietary supplement is still underestimated and under-reported. Vitamin C (VC) has been recognized as an antioxidant with prominent hepatorenal protective effects. This study investigated the possible preventive activity of VC against BLD-induced hepatorenal damage. Forty adult male Wistar rats were classified into five groups: control, vehicle control, VC (orally given 120 mg/kg b. wt./day), BLD (intramuscularly injected 5 mg/kg b. wt./week), and BLD + VC-treated groups. The experiment continued for eight weeks. Serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured. Serum contents of total protein (TP), albumin (ALB), globulin, total cholesterol (TC), triglycerides (TG), high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C), and very-low-density lipoprotein-cholesterol (VLDL-C) were also assayed. Urea, creatinine, and uric acid levels were determined together with sodium and potassium electrolytes measuring. Moreover, oxidative stress indicators including reduced glutathione (GSH), glutathione peroxidase (GPx), glutathione-S-transferase (GST), and glutathione reductase (GSR) as well as malondialdehyde (MDA) levels were measured in both hepatic and renal tissues. Corresponding histological examination of renal and hepatic tissues was conducted. Besides, immunohistochemical evaluations for androgen receptors protein (AR) and heat shock protein 90 (Hsp 90) expressions were performed. BLD caused significant rises in serum ALT, AST, TP, ALB, TC, TG, LDL-C, VLDL-C, urea, creatinine, uric acid, potassium, and MDA levels. Further, BLD-injected rats showed significant declines in the serum levels of HDL-C, sodium, GSH, GPx, GST, and GSR. Besides, distinct histopathological perturbations were detected in renal and hepatic tissues of BLD-injected rats. AR and Hsp 90 immunoexpression were increased in hepatic and renal tissues. In contrast, VC significantly reversed the BLD-induced hepatorenal damage in co-treated rats but not ameliorated AR protein overexpression. VC could be an efficient preventive supplement for mitigating BLD-induced hepatorenal damage, possibly via controlling oxidative stress events.

Abstract
The aim of this study was to evaluate the blood levels of folic acid, vitamin B12, and 25-hydroxyvitamin D (25-OHD) in patients with lead poisoning compared with control subjects in Eastern Iran. This analytical case-control study was conducted on 40 lead-poisoned patients who were referred to Imam Reza Hospital in Birjand from 2018 to 2019. Blood samples were collected from an additional 40 individuals without lead poisoning as a control group. The results indicated that the mean vitamin B12, vitamin D, and folic acid levels for the case group were 356.5 ± 200.1 pg/ml, 24.38 ± 9.5 ng/ml, and 7.4 ± 3.7 ng/ml, respectively. Mean folic acid level in the case group was significantly lower than control group (7.4 ng/ml vs. 12.70 pg/ml, P = 0.001), whereas the mean of the vitamin D levels at the case group was significantly higher than that of the control group (24.3 ng/ml vs. 20.1 ng/ml, P = 0.03). Moreover, mean vitamin B12 levels were significantly lower in the case group in comparison with the control group (356.5 pg/ml vs. 500.8 pg/ml) (P < 0.001). In the control group, 3 patients had folic acid below normal level (< 6 ng/mL) while 12 cases had folic acid below normal (P < 0.05). Also, none of the control group had low vitamin B12 concentrations (< 180 pg/ml), while 7 cases had vitamin b12 below normal (P < 0.05). Our results suggest that lead may induce folate and vitamin B12 dysregulation. Although we found that vitamin D levels were insufficient in both case and control groups, they were significantly higher in the case group. The interpretation of this result is unclear given inconsistent literature reports on this relationship.

Abstract
Lead (Pb) neurotoxicity is a major concern, particularly in children. Developmental exposure to Pb can alter neurodevelopmental trajectory and has permanent neuropathological consequences, including an increased vulnerability to further stressors. Ascorbic acid is among most researched antioxidant nutrients and has a special role in maintaining redox homeostasis in physiological and physio-pathological brain states. Furthermore, because of its capacity to chelate metal ions, ascorbic acid may particularly serve as a potent therapeutic agent in Pb poisoning. The present review first discusses the major consequences of Pb exposure in children and then proceeds to present evidence from human and animal studies for ascorbic acid as an efficient ameliorative supplemental nutrient in Pb poisoning, with a particular focus on developmental Pb neurotoxicity. In doing so, it is hoped that there is a revitalization for further research on understanding the brain functions of this essential, safe, and readily available vitamin in physiological states, as well to justify and establish it as an effective neuroprotective and modulatory factor in the pathologies of the nervous system, including developmental neuropathologies.

Abstract
Recently, oxidative stress is a common denominator in the pathogenesis of metal-induced neurotoxicity. Thus, antioxidant therapy is considered as a promising strategy for treating lead-related cognitive impairment. Here, we tested the hypothesis that astragaloside IV (AS-IV) ameliorates lead-associated cognitive deficits through Nrf2-dependent antioxidant mechanisms. Male Nrf2-KO and WT mice received drinking water with 2000 ppm lead and/or AS-IV by gavage for 8 weeks starting at 4 weeks of age. Morris water maze test and biochemical assays were employed to study cognition-enhancing and antioxidant effects of AS-IV. The signaling pathways involved were analyzed using RT-PCR and western blot technology. Significantly, AS-IV attenuated Morris water maze-based cognitive impairment in lead-intoxicated mice. Importantly, cognition-enhancing effect of AS-IV was lost in Nrf2-KO mice. In parallel, AS-IV suppressed lead acetate (PbAc)-induced oxidative stress, as measured by MDA. Mechanistically, AS-IV can up-regulate the expressions of the GCLc and HO-1 at the level of transcription and translation, but not SOD, TrxR activity, GCLm, Trx1, and NQO1 expression. Interestingly, AS-IV induced accumulation of Nrf2 in the nucleus, whereas Nrf2 mRNA levels were unchanged. Furthermore, AS-IV treatment resulted in elevated levels of phosphorylated Akt (active form) and phosphorylated GSK-3β (inactive forms) but decreased level of phosphorylated Fyn. Collectively, our findings indicate that AS-IV may target Nrf2 to attenuate lead-triggered oxidative stress and subsequent cognitive impairments, suggesting that AS-IV is a potential candidate for the treatment of lead-associated cognitive diseases.

Abstract
This study was aimed at investigating the neuroprotective effect of Vitexin against lead (Pb) induced neurodegenerative changes in the dorsolateral prefrontal cortex (DLPFC) and working memory in mice. Thirty-two adolescent male albino mice were divided into four groups (n=8). Control group received 0.2 mL of normal saline; Pb group received 100 mg/kg of Pb acetate for 14 days, Vitexin group received 1mg/kg of Vitexin for 14 days, and Pb+Vitexin group received 100 mg/kg of Pb acetate and 1 mgkg of Vitexin for 14 days. Barnes maze test and novel object recognition test were done to ascertain working memory. Histoarchitectural assessment of DLPFC was done with haematoxylin and eosin (H&E), cresyl fast violet and congo red stains. Furthermore, cell count and other morphometric measurements were done. There was significant decline in working memory in the Pb group, but a combination of Pb+Vitexin improved the working memory. Vitexin significantly reduced neuronal death and chromatolysis caused by Pb. Amyloid aggregation was not observed in any of the groups. This study has shown that concurrent administration of Vitexin and Pb will significantly reduce neurodegeneration and improve working memory. However, Pb treatment or Pb+Vitexin treatment does not have any effect on intercellular distance, neuronal length and the cross-sectional area of neurons in layer III of DLPFC.

Abstract
:
Tramadol is a synthetic analog of codeine used to treat pain of moderate to severe intensity
and is reported to have neurotoxic potential. At therapeutic dose, tramadol does not cause major side
effects in comparison to other opioid analgesics, and is useful for the management of neurological
problems like anxiety and depression. Long term utilization of tramadol is associated with various neurological
disorders like seizures, serotonin syndrome, Alzheimer’s disease and Parkinson’s disease.
Tramadol produces seizures through inhibition of nitric oxide, serotonin reuptake and inhibitory effects
on GABA receptors. Extensive tramadol intake alters redox balance through elevating lipid peroxidation
and free radical leading to neurotoxicity and produces neurobehavioral deficits. During Alzheimer’s
disease progression, low level of intracellular signalling molecules like cGMP, cAMP, PKC
and PKA affect both learning and memory. Pharmacologically tramadol produces actions similar to Selective
Serotonin Reuptake Inhibitors (SSRIs), increasing the concentration of serotonin, which causes
serotonin syndrome. In addition, tramadol also inhibits GABAA receptors in the CNS has been evidenced
to interfere with dopamine synthesis and release, responsible for motor symptoms. The reduced
level of dopamine may produce bradykinesia and tremors which are chief motor abnormalities in Parkinson’s
Disease (PD).

Abstract
Tramadol is a common analgesic, frequently used for relieving moderate or severe pain and widely used to delay ejaculation. However, repeated large doses have several adverse effects, especially on the brain tissue. So, this study was designed to assess the potentially deleterious effects of chronic administration of tramadol on principal fields of the hippocampus in adult and juvenile male albino mice. Thirty swiss male albino mice were divided equally into three groups: Group Ia (control adult) 3 months old, Group Ib (control juvenile) 3-week postnatal mice, Group II (tramadol treated adult mice) and Group III (tramadol treated juvenile mice). Both treated groups received tramadol tablets dissolved in water in a dose of 40mg/kg for 1 month by gastric tube. Tramadol treated groups showed degenerative changes in dentate gyrus (DG) granule cells, pyramidal neurons of CA1and CA3 fields in the form of electron-dense or rarified cytoplasm, dilated rER and mitochondrial changes. Additionally, immunohistochemical results revealed significantly increased in caspase 3 positive cells in different hippocampal principal fields. Astrogliosis and microgliosis were proved by the increased immunoreactivity of astrocytes to glial fibrillary acidic protein (GFAP) and microglia to CD68. Morphometric findings showed a significant reduction of both surface area of granule and pyramidal cells, and in thickness of DG, CA1, CA3 layers. Moreover, most of these morphological changes were aggravated in the juvenile-treated group. So, it can be concluded that tramadol abuse can induce an altered morphological change on the principal fields of the hippocampus in adult and juvenile mice.

Abstract
Lead is known as an environmental contaminant with neurotoxic properties. In addition, people experience different types of chronic stress, especially in developing countries. It has been established that lead or stress causes structural and physiological damages to the neural pathway like dopaminergic connections. Nevertheless, the effect of lead and restraint stress on movement behaviors when are experienced together has not been studied yet. In this study, male albino mice were randomly divided into different groups (n = 6). Lead acetate was daily injected at 15 mg/kg intraperitoneally for 2, 4, or 6 weeks. Restraint stress (6 h in a day) was applied alone or in combination with lead acetate for 2, 4, or 6 weeks. The catalepsy, akinesia, and the balance of animals were measured by bar test, elevated beam device, and rotarod to evaluate the movement disorders. 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine, a known neurotoxin causes movement disorders, was used as positive control group. The results showed that exposure to the lead or stress or their combination for 6 weeks caused catalepsy, akinesia, and imbalance in the animals, while exposure for 2 or 4 weeks didn’t affect the movement items indices. The combination of lead and stress did not show any significant difference compared to the exposure to each of them individually. From the findings, Lead, stress, and their combination caused movement disorders in a time dependent manner. Short time exposure did not change movement behavior. The co-exposure to the lead and stress did not show additive or synergistic effects.

The Independent and Combined Effects of Omega-3 and Vitamin B12 in Ameliorating Propionic Acid Induced Biochemical Features in Juvenile Rats as Rodent Model of Autism. J Mol Neurosci 2018; 66:403-413. [PMID: 30284229 DOI: 10.1007/s12031-018-1186-z] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2018] [Accepted: 09/24/2018] [Indexed: 12/12/2022]
Abstract
Metabolites of proper fatty acids modulate the inflammatory response and are essential for normal brain development; equally, abnormal fatty acid metabolism plays a critical role in the pathology of autism. Currently, dietary supplements are often used to improve the core symptoms of Autism spectrum disorder (ASD). The present study analyzed the effects of orally supplemented omega-3 (ω-3) and vitamin B12 on ameliorating oxidative stress and impaired lipid metabolism in a propionic acid (PPA)-induced rodent model of autism, together with their effect on the gut microbial composition, where great fluctuations in the bacterial number and strains were observed; interestingly, polyunsaturated fatty acids such as omega-3 induced higher growth of the gram-positive bacterium Staphylococcus aureus and decreased the survival rates of Clostridia sp. as well as other enteric bacterial strains. Thirty-five young male western albino rats were divided into five equal groups. The first group served as the control; the second group was given an oral neurotoxic dose of PPA (250 mg/kg body weight/day) for 3 days. The third group received an oral dose of ω-3 (200 mg/kg body weight/day) for 30 days after the 3-day PPA treatment. Group four was given an oral dose of vitamin B12 (16.7 mg/kg/day) for 30 days after PPA treatment. Finally, group five was given a combination of both ω-3 and vitamin B12 at the same dose for the same duration after PPA treatment. Biochemical parameters related to oxidative stress and impaired fatty acid metabolism were investigated in the brain homogenates of each group. The effects of the dietary supplements on the gut microbiota were also observed. The PPA-treated autistic model expressed significantly higher levels of lipid peroxides and 5-lipoxygenase (5-LOX) and significantly less glutathione (GSH), glutathione S-transferase (GST), and cyclooxygenase 2 (COX2) than the control group. However, a remarkable amelioration of most of the impaired markers was observed with oral supplementation with ω-3 and vitamin B12, either alone or in combination. Our results concluded that impairment at various steps of the lipid metabolic pathways may contribute to the development of autism; however, supplementation with ω-3 and vitamin B12 can result in a positive therapeutic effect.

The effects of tramadol administration on hippocampal cell apoptosis, learning and memory in adult rats and neuroprotective effects of crocin. Metab Brain Dis 2018; 33:907-916. [PMID: 29470767 PMCID: PMC5956046 DOI: 10.1007/s11011-018-0194-6] [Citation(s) in RCA: 37] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/12/2017] [Accepted: 01/22/2018] [Indexed: 02/07/2023]
Abstract
Tramadol, a frequently used pain reliever drug, present neurotoxic effects associated to cognitive dysfunction. Moreover, crocin has been reported to have neuroprotective effects. The aim of this study was to assess crocin's capacity to protect learning, and memory abilities on tramadol-treated rats. A total of 35 rats were divided into five groups: Control, Saline, tramadol (50 mg/kg), tramadol + crocin(30 mg/kg), crocin groups and treated orally for 28 consecutive days. Morris water maze (MWM) and passive avoidance (PA) tests were done, followed by dissection of the rat's brains for toluidine blue and TUNEL staining. In MWM test, tramadol group spent lower time and traveled shorter distance in the target quadrant (Q1) (P < 0.05). On the other side, the traveled distance in tramadol-crocin group was higher than tramadol (P < 0.05). In PA test, both the delay for entering the dark, and the total time spent in the light compartment decreased in tramadol comparing to the control group (P < 0.05), while it increased in tramadol-crocin compared with the tramadol group (P < 0.05). In tramadol-treated animals, the dark neurons (DNs) and apoptotic cells in CA1, CA3 and DG increased (P < 0.05), while concurrent intake of crocin decreased the number of DNs and apoptotic cells in these areas (P < 0.05). Crocin was able to improve learning and memory of tramadol-treated rats and also decreased DNs and apoptotic cells in the hippocampus. Considering these results, the potential capacity of crocin for decreasing side effects of tramadol on the nervous system is suggested.
