Effects of four-week lasting aerobic treadmill training on hepatic injury biomarkers, oxidative stress parameters, metabolic enzymes activities and histological characteristics in liver tissue of hyperhomocysteinemic rats.

Disruptions in homocysteine (Hcy) metabolism may increase the liver's susceptibility to developing conditions such as alcoholic liver disease, viral hepatitis, hepatocellular carcinoma (HCC), and cirrhosis. The aim of this study was to examine effects of aerobic treadmill training on hepatic injury biomarkers in sera, oxidative stress parameters, the activity of metabolic enzymes, and histological characteristics in the liver tissue of rats with experimentally induced hyperhomocysteinemia. Male Wistar albino rats were divided into four groups (N = 10, per group): C-saline 0.2mL/day sc. 2×/day for 14days + saline 0.5mL ip.1×/day for 28days; H-homocysteine 0.45µmol/g b.w. 2×/day for 14days + saline 0.5mL ip.1×/day for 28days; CPA-saline 0.2mL/day sc. 2×/day for 14days + aerobic treadmill training for 28days; and HPA-homocysteine 0.45µmol/gb.w. 2×/day for 14days + aerobic treadmill training for 28days. The serum albumin concentration was decreased in both physically active (PA) groups compared to sedentary groups. Concentration of malondialdehyde in liver tissue homogenates was lower in both PA groups compared to the H group. The total lactate dehydrogenase and malate dehydrogenase activities were significantly elevated in the HPA group compared to the C and H groups. Activities of aminotransferases in sera samples, and activities of catalase and superoxide dismutase in liver tissue did not significantly differ between groups. No significant histological changes were found in liver tissue in groups. This study demonstrated that aerobic treadmill training can reduce lipid peroxidation in liver tissue under hyperhomocysteinemic conditions, providing a protective effect. However, hyperhomocysteinemia can alter energy metabolism during aerobic exercise, shifting it toward anaerobic pathways and leading to elevated lactate dehydrogenase activity in the liver. Given that conditions like hyperhomocysteinemia are associated with an increased risk of cardiovascular diseases and liver damage, understanding how exercise influences these dynamics could guide therapeutic approaches.

EFFICACY OF CHROMOLAENA ODORATA SUPPLEMENTATION ON METHOTREXATE -INDUCED NEPHROPATHY AND OXIDATIVE STRESS

We carried out this research to investigate nephro-protective efficacy of Chromolaena odorata aqueous leaf extract on kidney toxicity in Methotrexate (MTX)-induced albino male rats. Thirty (30) wistar male rats spread into five study groups were used. Group I: orally administered normal saline daily and was the normal control. Group II: received C. odorata extract (250 mg/kg B.W.) orally once daily for ten days. Group III: received MTX (7mg/kg B.W.) intraperitoneally from 8th day for three days consecutively. Group IV: received C. odorata extract (250 mg/kg B.W.) orally once daily for ten days and then administered MTX (7 mg/kg B.W.) intraperitoneally from 8th day for three days consecutively. Group V: received Vitamin C (100 mg/kg B.W.) orally once daily for ten days and then administered MTX (7 mg/kg BW) intraperitoneally from 8th day for three days consecutively. 24hours after last treatment and administration, all rats were sacrificed and blood collected in EDTA bottles for hematology or in plain tubes for biochemical analysis. Creatinine and Urea were analyzed in serum. Superoxide Dismutase (SOD), Catalase, Malondialdehyde (MDA) and histopathological analysis was assessed using the kidney tissues. The obtained results revealed that three days of consecutive Methotrexate administration caused a significant rise in kidney function activity as well as severe oxidative damage and oxidative stress shown by a significant rise in Creatinine and Urea, increased level of MDA and a significant drop in SOD and CAT. However, C. odorata attenuated Methotrexate-induced biochemical alterations and oxidative stress in kidney. Also, C. odorata alone or in combination with Methotrexate showed an increase in Packed Cell Volume (PCV), Red Blood Cells (RBC), Haemoglobin (HB), White Blood Cells (WBC) and Platelets level compared to the group administered Methotrexate alone which showed degenerative levels in the analyzed hematological parameters. Showing corroboration, histopathological analysis showed deterioration and collapse of the kidney tubules in rats administered Methotrexate alone whereas C. odorata groups showed considerable nephro-protection and restoration towards normalcy. The results from this study revealed that the C. odorata have a nephro-protective efficacy against Methotrexate-induced kidney toxicity and damage via scavenging of free radicals and stabilization/enhancement of endogenous antioxidant status

Effect of pure (ligand-free) nanoparticles of magnetite in sodium chloride matrix on hematological indicators, blood gases, electrolytes and serum iron

AbstractOne of the physical methods for obtaining magnetite nanoparticles (NPs) is electron beam physical vapor deposition (EB PVD), which requires complex equipment, but allows obtaining a significant amount of pure (ligand-free) NPs. The biomedical application of such NPs is less studied than materials from other synthesis methods. The objective is to study the effect of pure magnetite NPs in the NaCl matrix obtained by EB PVD on hematological indicators, gases, electrolytes and parameters of iron metabolism in the blood of intact animals. The physical characteristics of NPs were studied using high-resolution transmission electron microscopy, scanning transmission electron microscopy, energy-dispersive X-ray spectroscopy mapping, electron energy-loss spectroscopy, selected area electron diffraction and fast Fourier transform. In vivo experiments were conducted on albino male rats, which were injected with solution of magnetite-sodium chloride NPs (1.35 mg Fe/kg). After 3 and 72 h, hematological parameters, blood gases, electrolytes, and serum iron were determined. The synthesized NPs had an average size of 11 nm. They were identified as magnetite, where polycrystals and single crystals were present. The absence of contamination in crystal boundaries, clear orientation and orderliness of atoms in crystals were established. The administration of NPs in the sodium chloride matrix to animals was characterized by a transient increase in the main indicators of red blood accompanied by an increase in the saturation of erythrocytes with hemoglobin and their mean volume after 3 h. It did not worsen blood gases and pH, but decreased blood Na+ content after 72 h. The investigated NPs caused changes in the parameters of serum iron characteristic to iron preparations, which after 3 h were smaller compared to the reference iron drug, and after 72 h—similar to it. More intense rapid effects on hematological parameters at lower serum iron indicate greater activity of the studied pure magnetite NPs obtained by EB PVD syntesis compared to the reference iron preparation.

Effect of curcumin and cacao extract on interleukin-6 expression on ribociclib-induced hepatotoxicity in rats

Purpose: To assess the relationship between interleukin-6 (IL-6) expression and the protective effect of curcumin and cacao extract on hepatotoxicity caused by ribociclib. Method: Sixty adult male albino rats (9 – 10 weeks old) were utilized in this experiment. The rats were separated into six groups (n = 10 each). Group 1 (control) rats received 2 mL of normal saline daily. Group 2 rats were administered 5 mg/kg ribociclib and group 3 rats received 5 mg/kg ribociclib with a cacao dose of 200 mg/kg daily. Group 4 rats were administered 5 mg/kg ribociclib treated with curcumin (200 mg/kg) daily. Groups 5 and 6 were administered cacao and curcumin doses of 200 mg/kg daily. All rats were sacrificed and liver immunohistochemical and histological examinations were performed. Result: The findings demonstrated that ribociclib administration caused liver damage and morphological changes at a histological level in liver tissue. The immunohistochemical investigation revealed that IL-6 levels were significantly increased in group 2 and control group (p < 0.05). Furthermore, co-administration of curcumin and cacao with ribociclib suppressed the levels of IL-6 expression in the liver tissue of rats compared to control group 1. Conclusion: Co-administration of curcumin and cacao protects the liver against ribociclib-induced liver damage. It is necessary to determine the effect of long-term administration of these extracts on the functions of some organs such as the liver and kidney.

Evaluation of the therapeutic potential of novel nanoparticle formulations of glutathione and virgin coconut oil in an experimental model of carbon tetrachloride-induced liver failure.

Acute liver failure (ALF) is a critical condition characterized by rapid liver dysfunction, leading to high mortality rates. Current treatments are limited, primarily supportive, and often require liver transplantation. This study investigates the potential of a novel nanoparticle formulation of glutathione (GSH) and virgin coconut oil (VCO) alone and in combination to enhance therapeutic outcomes in a rat model of ALF induced by orogastric carbon tetrachloride (CCl4). The study employed adult male Albino rats divided into ten groups, with ALF induced via a single oral dose of CCl4. Various treatment regimens were administered over seven days, including conventional and nanoparticle forms of GSH and VCO and their combinations. The efficacy of treatments was evaluated through biochemical analysis of liver function markers, oxidative stress indicators, inflammatory biomarkers, and histopathological examinations. Nanoparticles were synthesized using established methods, and characterization techniques were employed to ensure their quality and properties. The nanoparticle formulations significantly improved liver function, as indicated by reduced serum levels of alanine aminotransferase and aspartate aminotransferase, alongside decreased oxidative stress markers such as malondialdehyde. Furthermore, they reduced tumor necrosis factor alpha and interleukin-1 beta inflammatory markers. Histological analysis revealed reduced hepatocellular necrosis and inflammation in treated groups compared to controls. Also, decreased nuclear factor-kappa B was detected by immunohistochemical analysis. The findings show that the nanoparticle mixture of GSH and VCO effectively reduces liver damage in ALF. This suggests a promising drug-based approach for improving liver regeneration and protection. This innovative strategy may pave the way for new therapeutic interventions in the management of ALF.

Antilithiatic Activity of Arbutus Pavarii (Shemeri) Extract on Ethylene Glycol Induced Lithiasis in Rats

Objectives. The objective of this study was to investigate the antilithiatic activity of shemeri (Arbutus Pavarii) on ethylene glycol-induced urolithiasis in male albino rats. Methods. 24 healthy male albino rats were divided into 4 groups. The rats in group A served as the normal control group. Group B (EG-treated group) rats received 0.75% ethylene glycol for three weeks followed by drinking water for the next 3 weeks. Group C (preventive group) rats received 0.75% ethylene glycol along with shemeri for six weeks. Group D (treatment group) rats received 0.75% ethylene glycol for three weeks then supplemented with shemeri aqueous solution. After six weeks, various levels of oxalate, calcium, and phosphate in urine and serum levels of creatinine, urea, uric acid, phosphate, calcium, and sodium were measured. Histopathological examination for kidney samples was also conducted. Results. In comparison to the EG-treated group, oral administration of Arbutus Pavarii (shemeri) significantly lowered elevated levels of creatinine, urea, and uric acid while, significantly increased levels of phosphate, calcium, and sodium in the serum. Shemeri also reduced elevated levels of urinary oxalate, calcium, and phosphate. Histopathological examination showed noticeable kidney lesions in group (B), but these lesions improved in groups (C, and D). Conclusion. This study suggests that shemeri is a promising and effective plant in prevention and treatment of Ethylene glycol-induced urolithiasis in male albino rats.

Assessment of IV albumin and ringer lactate on the acute oral toxicity of acetylsalicylic acid in albino rats

BackgroundDespite the frequent inclusion of fluid therapy in the treatment of many conditions, there are limited studies available to provide an evidence-based specific recommendation for fluid therapy in acute drug toxicity. Salicylate toxicity is considered one of the common clinical problems. It is commonly associated with fatal complications and even can lead to death. The study was designed to investigate the effects of various IV fluid types as isotonic saline (NaCl 0.9%), Ringer lactate (RL), and albumin and their impact on acetyl salicylic acid (ASA) toxicity outcome in a rat model of acute salicylate toxicity.Sixty male Albino rats were divided into 10 groups of 6 rats each. The first four groups were the control, saline, RL, and albumin groups. The fifth group received two doses of ASA solution orally, and the next five groups were treated with IV fluids as follows: saline-ASA, RL-ASA, albumin-ASA, RL + albumin-ASA, and saline + albumin-ASA. Upon completion of the study, spirometry, arterial blood gas analysis (ABG), and serum liver and kidney function tests were done on all groups. Furthermore, quantitative real-time polymerase chain reaction (PCR) was used to assess interleukin-6 (IL6), nuclear factor kappa beta (NF-kβ), and beta-actin mRNA gene expression of histopathology and immunohistochemistry assessments were also performed on liver and kidney tissues.ResultsThe results revealed the ASA group showed marked deterioration across all the investigated parameters. The groups that received saline and RL showed improvements in the following: respiratory rates, ABG, liver and kidney function, and histopathological findings.The RL + albumin group did not show any improvements. The albumin group and the saline + albumin group showed variable responses, ranging from mild improvement to no improvement.ConclusionsThe saline and RL groups showed positive results; however, the RL + albumin group showed the worst outcomes. The inclusion of albumin did not appear to provide any extra benefits and produced varying results.

Exploring the protective role of green tea extract against cardiovascular alterations induced by chronic REM sleep deprivation via modulation of inflammation and oxidative stress

BackgroundChronic Rapid eye movement (REM) sleep deprivation has been associated with various cardiovascular alterations, including disruptions in antioxidant defense mechanisms, lipid metabolism, and inflammatory responses. This study investigates the therapeutic potential of green tea extract (GTE) in mitigating these adverse effects.MethodsA total of 24 male Wistar albino rats were used in this study and divided into the control group (n = 8), Chronic-REM Sleep Deprivation (CRSD) Group (n = 8) and Chronic-REM SD + Green Tea 200 (CRSD + GTE200) Group (n = 8). After 21 days, a comprehensive analysis of paraoxonase (PON1), arylesterase (ARE), malondialdehyde (MDA), glutathione (GSH), nitric oxide (NOx), proinflammatory cytokines, and lipid profiles in aortic tissue, heart tissue, and serum was conducted in a sleep-deprived rat model.ResultsChronic REM sleep deprivation led to a significant reduction in PON1 and ARE levels in aortic (p = 0.046, p = 0.035 respectively) and heart tissues (p = 0.020, p = 0.019 respectively), indicative of compromised antioxidant defenses. MDA levels increased, and NOx levels decreased, suggesting oxidative stress and impaired vascular function. Lipid profile alterations, including increased triglycerides and total cholesterol, were observed in serum. Elevated levels of inflammatory cytokines (IL-6 and TNF-alpha) further indicated an inflammatory response (p = 0.007, p = 0.018 respectively). GTE administration demonstrated a protective role, restoring antioxidant enzyme levels, suppressing lipid peroxidation, and improving NOx levels.ConclusionThese findings suggest the therapeutic potential of GTE in alleviating the cardiovascular impairments of chronic REM sleep deprivation, emphasizing its candidacy for further clinical exploration as a natural intervention in sleep-related disorders and associated cardiovascular risks.

Effects of Apelin-13 on auditory system in STZ-induced diabetic rats

AimDamage to the auditory pathways is one of the complications of diabetes. The aim of this study was to investigate the potential therapeutic effects of apelin-13 in the auditory pathways of rats with experimentally induced diabetes by examining its effect on auditory brainstem responses, cochlear oxidative stress and inflammatory cytokines. MethodsThirty-two male Wistar albino rats were divided into four groups: sham control, diabetes, apelin and diabetes + apelin. A single dose of 45 mg/kg streptozotocin (STZ) was administered to induce diabetes. The apelin group received 50 µg/kg apelin-13 for seven days intraperitoneally (ip). At the end of the apelin and STZ applications auditory brainstem responses (ABR) was recorded. At the end of the experiment, cochlea was removed and biochemical analyzes were performed. ResultsIn ABR recordings, the latencies of wave V in diabetic group were observed to be longer than those of the control, with the apelin treatment exhibiting a partial reversal of this situation, particularly at specific frequencies and intensity levels. Apelin treatment leads to a significant increase in total antioxidant status (TAS) and a reduction in total oxidant status (TOS) and oxidative stress index (OSI) in cochlea compared to diabetic groups. The levels of tumor necrosis factor-alpha (TNF-alpha) and interleukin 1-beta (IL-1 beta) in cochlear tissue were found to be significantly reduced in the apelin-treated group compared to the diabetic group. ConclusionApelin-13 may have a protective effect on the auditory system and may be proposed as a potential new therapeutic strategy for the management diabetic auditory impairment.

Chronic pregabalin treatment reduced anxiety, and acute pregabalin treatment increased depression-like behaviors in rats

BackgroundPregabalin is an antiepileptic drug that binds to the alpha-2/delta unit at presynaptic voltage-dependent calcium channels. We aimed to investigate the effect of acute and chronic pregabalin administration on anxiety and depression-like behaviors.MethodsFifty-six male Wistar albino rats were divided into seven groups: control, vehicle, and five different dose groups (5, 10, 30, 60, and 100 mg/kg). Pregabalin was administered for two weeks. Depression-like behaviors were evaluated by Forced swimming test. Anxiety-like behavior (ALB) was evaluated by Open field test (OFT), Elevated Plus Maze (EPM), and light-dark box. Subjects underwent the forced swimming test (FST) after the first dose, while the open field test (OFT), elevated plus maze (EPM), and light-dark box (LDB) were performed after two weeks of treatment. Further sucrose preference test was conducted to evaluate anhedonia until the end of the experiment.ResultsIn the forced swimming test, depression-like behaviors increased after acute single-dose administration of 10, 30, 60, 100 mg/kg pregabalin. According to OFT results, chronic 100 mg/kg pregabalin showed anxiolytic effects by decreasing grooming, and freezing behaviors. In addition, 100 mg/kg chronic pregabalin administration significantly increased the time spent in the central region, the number of entries to the center, and the unsupported rearing number without causing any change in locomotor activity. According to EPM results, both chronic 60 and 100 mg/kg pregabalin treatments showed anxiolytic effects by increasing open arm time and head dipping behavior. In addition, 60 and 100 mg/kg chronic pregabalin administration significantly decreased stretch attend posture. All pregabalin administrations between 5 and 100 mg/kg displayed anxiolytic effects in the LDB. Sucrose preference was above 65% for the duration of all experiments and subjects did not show anhedonia.ConclusionAcute pregabalin treatment triggered depression-like behaviors. Anhedonia, which may be associated with depression, was not observed during chronic treatment. Moreover, chronic treatment with pregabalin revealed potent anxiolytic effects in different behavior patterns and doses for all tests of unconditional anxiety. In particular, 100 mg/kg chronic pregabalin administration decreased anxiety-like behaviors in all experiment setups. Although the anxiolytic effect was demonstrated in chronic treatment, acute treatment of pregabalin induced depression-like behaviors, and thus in clinical practice should be done with caution, especially in patients with anxiety-depression comorbidity.

Ameliorative effects of Turbinaria ornata extract on hepatocellular carcinoma induced by diethylnitrosamine in-vivo.

Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related deaths and the fifth most common cancer worldwide. Brown algae appeared to be a rich source of efficient and safe agents against many life-threatening diseases like cancer. Thus, the scope of this study was to investigate the therapeutic effects of Turbinaria ornata against experimentally induced HCC in a rat model. Accordingly, forty male albino rats were divided into four groups. HCC was induced by intraperitoneal injection with diethylnitrosamine (DENA) followed by carbon tetrachloride (CCL4). After four weeks of DENA + CCL4 injection and two weeks of treatment with Turbinaria ornata, rats were sacrificed to collect hepatic tissue and blood samples for histopathological observations and various biochemical markers such as aspartate aminotransferase (AST), alanine aminotransferase (ALT), alpha-fetoprotein (AFP), urea, creatinine, albumin (ALB), and alkaline phosphatase (ALP). Rats that were injected for four weeks with DENA + CCL4 showed a significant increase in AFP levels, transforming growth factor-beta (TGF-β) and tumor necrosis factor-alpha (TNF-α), as well as a high percentage of malignant changes in hepatic tissues. The extension of malignant changes in the rat liver tissues was markedly reduced using Turbinaria ornata, as the treatment displayed liver patterns similar to that of the normal control rats. Furthermore, rats with HCC fed with Turbinaria ornata extract for two weeks showed decreasing levels of TGF-β and TNF-α. These findings demonstrate that Turbinaria ornata supplement can prevent HCC development in hepatic rats; however, the exact mechanism requires further investigation.

Reno-protective potential of poncirin against polyethylene microplastics instigated kidney damage in rats via regulating Nrf-2/Keap-1 pathway

Polyethylene microplastics (PEMPs) are noxious environmental pollutants that are documented to cause organ damage including the kidneys. Poncirin (PON) is a naturally occurring flavonoid which demonstrates a wide range of pharmacological properties. This experiment was conducted to evaluate the palliative potential of PON against PEMPs by examining a range of biochemical and physiological parameters. Twenty-four male albino rats were randomly apportioned into four distinct groups including the control, PEMPs (1.5 mgkg−1), PEMPs (1.5 mgkg−1) + PON (20 mgkg−1) & only PON (20 mgkg−1). Our results displayed that PEMPs intoxication escalated the levels of urea, KIM-1, creatinine & NGAL while demising the creatinine clearance level. Besides reduction in the activities of GPx, GST, HO-1, CAT, GSR & upsurge in the levels of MDA and ROS were detected in PEMPs group. Conversely, the levels of inflammatory markers including COX-2, IL-1β, NF-kB and TNF-α were augmented following the PEMPs intoxication. Besides, the results of current research demonstrated that levels of Bax & caspase-3 were more than normal whereas the Bcl-2 expression was lowered from its standard value due to PEMPs provision. However, PON treatment significantly restored the PEMPs-induced biochemical impairments. Therefore, PON could be used as a therapeutic compound to ameliorate PEMPs-induced kidney impairments in rats, possibly due to its tremendous pharmacotherapeutic potential.

Background: 4-MDMB-BUTINACA, a next-generation synthetic cannabinoid, presents significant public health and forensic challenges due to its evolving nature and potential toxicity. Methods: This study evaluates the subacute toxic effects and pharmacokinetics of 4−Fluoro MDMB−BUTINACA (4F-MDMB-BUTINACA) in adult male albino rats, administered orally for seven days at doses of 1 mg/kg, 5 mg/kg, and 15 mg/kg. The hematological, biochemical, and histopathological parameters were assessed and compared to controls. Results: The pharmacokinetics were determined using GC–MS/MS with a positive chemical ionization and granisetron as an internal standard. A histological analysis revealed inflammatory cell aggregation, congestion, hemorrhage, edema, and fibrosis in various tissues, with renal examinations showing tubule degradation, glomerular atrophy, Bowman’s space expansion, edema, and hemorrhage. The liver exhibited cellular infiltration, while cardiac muscle fibers showed myocardial fiber degradation and inflammatory cell aggregation. Biochemical assays indicated significant alterations (p < 0.05) in the serum levels of AST, ALT, ALP, GGT, total protein, albumin, triglycerides, urea, MCHC, MCV, RDW, platelets, neutrophils, eosinophils, and basophils compared to the controls. Conclusions: The validated bioanalytical method revealed rapid absorption of 4F-MDMB-BUTINACA, with a plasma half-life of 2.371 h, a volume of distribution of 2272.85 L, and a plasma clearance rate of 664.241 L/h. In conclusion, 4F-MDMB-BUTINACA is a highly toxic synthetic cannabinoid, particularly affecting the liver, kidneys, and heart.

Characterization and potential health benefits of millet flour and banana peel mixtures on rats fed with a high-fat diet

Millet (M) and banana peel (Bp) possess significant nutritional qualities and have been shown to reduce obesity resulting from a high-fat diet (HFD). The present research assessed the effect of millet flour and banana peel mixtures on lipid profiles, liver and kidney functions, and characterized food products derived from these mixtures. Thirty-five male albino rats were allocated into five groups for a biochemical analysis. The control group (n = 7) received a basal diet, while the remaining 28 rats were fed a high-fat diet (HFD) for 8 weeks to induce obesity. These rats were then separated into four sub-groups (n = 7 each): sub-group 1 as the positive control (+ve) receiving only HFD, while sub-groups 2, 3, and 4 were administered HFD supplemented with millet flour and banana peel mixtures (M90+Bp10 %, M80+Bp20 %, and M70+Bp30 %), respectively for an additional 8 weeks. The chemical composition analysis showed that banana peel (Bp) has higher levels of fat, ash, fiber, magnesium, and potassium, while millet flour is richer in carbohydrates. Bp also had superior antioxidant activity and total phenol content (13.32 % and 10.54 mg/100g) compared to millet flour (3.75 % and 4.55 mg/100g). Biochemical tests on the HFD plus (M70+Bp30 %) group revealed improved lipid profiles, leptin, antioxidant enzymes, and kidney and liver functions. Glucose levels were higher in the HFD group (137.33 mg/dl) than in the control (85.70 mg/dl), but these levels were reduced with millet and banana peel treatment. The histology of liver tissues confirmed the biochemical results. Sensory evaluation of pancakes and toast from the (M70+Bp30 %) mixture by forty panelists showed high acceptability, aligning with the biochemical outcomes. This study suggests that a banana peel and millet flour mixture could help reduce obesity.

Neuroprotective effects of punicalagin and/or micronized zeolite clinoptilolite on manganese-induced Parkinson's disease in a rat model: Involvement of multiple pathways.

Manganism, a central nervous system dysfunction correlated with neurological deficits such as Parkinsonism, is caused by the substantial collection of manganese chloride (MnCl2) in the brain. To explore the neuroprotective effects of natural compounds, namely, micronized zeolite clinoptilolite (ZC) and punicalagin (PUN), either individually or in combination, against MnCl2-induced Parkinson's disease (PD). Fifty male albino rats were divided into 5 groups (Gps). Gp I was used as the control group, and the remaining animals received MnCl2 (Gp II-Gp V). Rats in Gps III and IV were treated with ZC and PUN, respectively. Gp V received both ZC and PUN as previously reported for the solo-treated plants. ZC and/or PUN reversed the depletion of monoamines in the brain and decreased acetyl choline esterase activity, which primarily adjusted the animals' behavior and motor coordination. ZC and PUN restored the balance between glutamate/γ-amino butyric acid content and markedly improved the brain levels of brain-derived neurotrophic factor and nuclear factor erythroid 2-related factor 2/heme oxygenase-1 and decreased glycogen synthase kinase-3 beta activity. ZC and PUN also inhibited inflammatory and oxidative markers, including nuclear factor kappa-light-chain-enhancer of activated B cells, Toll-like receptor 4, nucleotide-binding domain, leucine-rich-containing family, pyrin domain-containing-3 and caspase-1. Bcl-2-associated X-protein and B-cell leukemia/lymphoma 2 protein (Bcl-2) can significantly modify caspase-3 expression. ZC and/or PUN ameliorated PD in rats by decreasing the levels of endoplasmic reticulum (ER) stress markers (p-protein kinase-like ER kinase (PERK), glucose-regulated protein 78, and C/EBP homologous protein (CHOP)) and enhancing the levels of an autophagy marker (Beclin-1). ZC and/or PUN mitigated the progression of PD through their potential neurotrophic, neurogenic, anti-inflammatory, antioxidant, and anti-apoptotic activities and by controlling ER stress through modulation of the PERK/CHOP/Bcl-2 pathway.
