This study investigated the probable protective effects of resveratrol (RES), an antioxidant, against methotrexate- (MTX-) induced testis damage. Twenty-four male Sprague Dawley rats were randomly divided into four groups: control, RES, MTX, and MTX + RES groups. Rats were sacrificed at the end of the experiment. Plasma and tissue malondialdehyde (MDA) levels, superoxide dismutase (SOD) and catalase (CAT) activity in tissue, testicular histopathological damage scores, and testicular and epididymal epithelial apoptotic index (AI) were evaluated. The MTX group had significantly higher plasma and tissue MDA levels and significantly lower SOD and CAT activity than those of the control group. In the MTX + RES group, plasma and tissue MDA levels decreased significantly and SOD activity rose significantly compared to the MTX group. The MTX group had significantly lower Johnsen’s testicular biopsy score (JTBS) values than those of the control group. JTBS was significantly higher in the MTX + RES group than in the MTX group. AI increased in the testis and epididymis in the MTX group and significantly decreased in the MTX + RES group. Our results indicate that RES has protective effects against MTX-induced testis damage at the biochemical, histopathological, and apoptotic levels.

Background and Aim: Several microRNAs are involved in regulating muscle mass, which plays an essential role in hypertrophy and atrophy of skeletal muscle, The present study examined the expression of some genes as regulators of muscular atrophy following a period of inertia in rats. Methods & Materials: For this purpose, 18 male Sprague-Dawley rats were divided into three groups (Control, Exercise+inactivity, and Inactivity). The exercise+inactivity group run on the treadmill for 18 weeks and five times per week. The hindlimb of the animal was immobilized for seven days with the casting method. Soleus muscle was extracted and the expression of the genes was measured by the RT-PCR method. Univariate ANOVA and Tukey post hoc test was used to determine the differences (α=0.05). Ethical Considerations: The Ethics Committee of the Tehran University of Medical Sciences Research approved this study (Code: IR.SUMS.REC.1396.S 463). Results: Results showed that immobilization in both Exercise+ inactivity and inactivity groups, compare to the control group, increased expression of miR-1 genes (P<0.10), FOXO3a (P<0.001) and decreased expression of miR-206 (P<0.007) and IGF-1 (P<0.001). This difference was statistically significant. Conclusion: According to the results of this study, it can be said that changes in the expression of RNAs by chromatography cause changes in the expression of muscle regulating genes, and although endurance exercises have protective effects, they cannot prevent these changes.

Summary The aim of this study was to investigate the exogenous agmatine influence on nitrosative and oxidative stress parameters in acute phase of multiple sclerosis (MS) experimental model, experimental autoimmune encephalomyelitis (EAE). EAE was induced by subcutaneous injection of myelin basic protein (50 μg per animal). Sprague-Dawley rats were divided into five groups: I group - (CG), treated by PBS (i.p.), II group - (EAE), III group - (CFA), treated with Complete Freund’s adjuvant (0.2 ml subcutaneously), IV group - (EAE+AGM), treated by agmatine (75 mg/kg bw i.p.) upon EAE induction and V group - (AGM), received only agmatine in the same dose. The animals were treated every day during experiment - from day 0 to 15, and clinically scored every day. They were sacrificed on day 16 from MBP application. NO2+NO3, S-nitrosothiols (RSNO), malondyaldehide (MDA) and reduced glutathione (GSH) concentrations and superoxide dismutase (SOD) activity were determined in rat whole encephalitic mass (WEM) and cerebellum homogenates. Agmatine exerted strong protective effects on EAE clinical symptoms (p<0.05). In EAE brain homogenates, NO2+NO3, RSNO and MDA concentrations were increased compared to CG values. Agmatine treatment diminished NO2+NO3, RSNO and MDA levels in EAE animals (p<0.05). In EAE rats, GSH level and SOD activity were decreased compared to CG values, but agmatine treatment increased both parameters compared to EAE untreated animals (p<0.05). Immunohistochemical staining supported the clinical and biochemical findings in all groups. The CNS changes in EAE are successfully supressed by agmatine application, which could be the the new aspect of the neuroprotective effects of agmatine.

Background: Sulodexide is a powerful antithrombin agent with reno-protective property. However, whether it has beneficial effects on Contrast-Induced Nephropathy (CIN) remained elusive. In the current study, we evaluated the therapeutic effects of Sulodexide on CIN and investigated the potential mechanisms. Methods: CIN model was induced by intravenous injection of indomethacin, followed by Ioversol and L-NAME. Sprague-Dawley rats were divided into 4 groups: control group, CIN group, CIN+vehicle group (CIN rats pretreated with vehicle) and CIN+ Sulodexide (CIN rats pretreated with Sulodexide). Sulodexide or an equivalent volume of vehicle was intravenously delivered 30 min before the induction of CIN. All the animals were sacrificed at 24h after CIN and tissues were harvested to evaluate renal injury, kidney oxidative stress and apoptosis levels. Plasma antithrombin III (ATIII) activities were also measured. Results: Compared to the untreated CIN group, improved renal function, reduced tubular injury, decreased levels of oxidative stress and apoptosis were observed in CIN rats receiving Sulodexide injection. In addition, we also found that ATIII activity was significantly higher in Sulodexide-administered group than that in vehicle-injected CIN rats. For in vitro studies, HK2 cells were exposed to Ioversol and the cyto-protective effects of Sulodexide were also determined. Sulodexide pretreatment protected HK2 cells against the cytotoxicity of Ioversol via inhibiting caspase-3 activity. Preincubation with Sulodexide could also attenuate H2O2-induced increases in ROS, apoptosis and caspase-3 levels. Conclusions: Taken together, Sulodexide could protect against CIN through activating ATIII, and inhibiting oxidative stress, inflammation and apoptosis.

Aim. The aim of this study was to compare the effects of sildenafil and trimetazidine on bilateral cavernosal nerve injury-induced oxidative damage and fibrotic changes in cavernosal tissue in rat model.Material and Methods. A total of 32 male Sprague-Dawley rats were randomly divided into 4 groups; each group consist 8 rats (control, BCI, BCI + TMZ, and BCI + sildenafil groups). Tissue superoxide dismutase (SOD), malondialdehyde (MDA), and protein carbonyl (PC) levels were determined biochemically and distribution of cavernosal fibrosis density among groups was performed histopathologically.Results. Tissue SOD levels in BCI group were significantly lower than the control group (P<0.05). Tissue MDA and PC levels in BCI group were significantly higher than the control group (P<0.05). TMZ and sildenafil administration significantly increased tissue SOD levels (P<0.05) and reduced tissue MDA and PC levels (P<0.05). Histologically, the degree of cavernosal fibrosis and collagen density was higher in BCI group in comparison to control, TMZ-treated, and sildenafil-treated groups.Conclusion. BCI caused oxidative damage and increased cavernosal fibrosis in rat penis. TMZ and sildenafil treatment decreased oxidative damage and reduced the degree of fibrosis in penile tissue due to BCI.

AbstractAging, a critical risk factor of several diseases, including neurodegenerative disorders, affects an ever-growing number of people. Cacao supplementation has been suggested to improve age-related neuronal deficits. Therefore, this study investigated the protective effects of raw cacao powder on oxidative stress-induced aging. Male Sprague–Dawley rats were divided into 4 groups: Control (C), d-galactose-induced aging (G), d-galactose injection with 10% (LC), and 16% (HC) cacao powder mixed diet. d-galactose (300 mg/3 mL/kg) was intraperitoneally injected into all but the control group for 12 weeks. Cacao supplemented diets were provided for 8 weeks. The levels of serum Malondialdehyde (MDA), Advanced Glycation End-products (AGEs), brain and liver MDA, the indicators of the d-galactose induced oxidative stress were significantly decreased in LC and HC but increased in G. The Acetylcholinesterase (AChE) activity of brain showed that the cholinergic impairment was significantly lower in LC, and HC than G. Furthermore, the expression levels of catalase (CAT), phospho-Akt/Akt, and procaspase-3 were significantly increased in LC and HC. In conclusion, cacao consumption attenuated the effects of oxidative stress, cholinergic impairment and apoptosis, indicating its potential in future clinical studies.

This study aims to investigate the protective effect ofCyphomandra betaceain adult male Sprague-Dawley rats fed with high fat diet. Rats were fed on either normal chow or high fat diet for 10 weeks for obesity induction phase and subsequently receivedC. betaceaextract at low dose (150 mg kg−1), medium dose (200 mg kg−1), or high dose (300 mg kg−1) or placebo via oral gavages for another 7 weeks for treatment phase. Treatment of obese rats withC. betaceaextracts led to a significant decrease in total cholesterol and significant increase in HDL-C (p<0.05). Also there was a trend of positive reduction in blood glucose, triglyceride, and LDL-C with positive reduction of body weight detected in medium and high dosage ofC. betaceaextract. Interestingly,C. betaceatreated rats showed positive improvement of superoxide dismutase (SOD) activity and glutathione peroxidase (GPx) activity along with a significant increase of total antioxidant status (TAS) (p<0.05). Further, rats treated withC. betaceashow significantly lower in TNF-αand IL-6 activities (p<0.05). This study demonstrates the potential use ofCyphomandra betaceaextract for weight maintenance and complimentary therapy to suppress some obesity complication signs.

Background: The relationship between liver diseases and neurological defects is well established. Hepatic encephalopathy (HE) has been seen both in people with acute liver failure (ALF) and chronic liver disease (CLF). HE is a complex neuropsychiatric syndrome that is seen in patients suffering from liver dysfunction. Silymarin (Sm) has antioxidant, anti-inflammatory, and anti-carcinogenic features. In this study, the possible protective effects of silymarin were investigated against dorsolateral prefrontal cortex (DLPFC) damage induced by thioacetamide (TAA). Method: To achieve this, male Sprague Dawley rats (200-250 g) were randomly divided into four groups, with 7 animals comprising each group: the control group, 50 mg/kg TAA group, 50 mg/kg Sm + TAA group, and 100 mg / kg Sm + TAA group. Results: Differences between the groups were determined by performing immunohistochemical analysis of the PFC. Bax, TNF-α, and TUNEL expression increased in the brain tissue of the experimental group where only TAA was administered. Conclusions: It was observed that in high doses in particular (100 mg/kg Sm + TAA group), Sm was effective in preventing PFC damage caused by TAA. It was determined that 100 mg/kg Sm significantly reduces TAA-induced inflammation (TNF-α and H&E) and apoptosis (Bax, TUNEL) in brain tissue.

Objective: To evaluate the protective effects of vitamin E α-tocopherol isomer against the toxicity of cisplatin on sperm motility and morphology in Sprague Dawley rats. Material & Methods: Twenty-four rats were grouped into four groups (n=6). The control group (CN) was injected with normal saline, second group (CP) was injected with cisplatin, the third group (P1) was injected with cisplatin and vitamin E 50 mg/kgBW for 7 weeks P.O, the fourth group (P2) was injected with cisplatin and vitamin E 200 mg/kgBW for 7 weeks P.O. Vitamin E was given from 3 weeks before cisplatin injection and 4 weeks following cisplatin injection. At 7th week, all the samples were undergoing bilateral orchidectomy. Vitamin E that being used in this study was α-tocopherol isomer. Results: Cisplatin decreased motility and morphology of spermatozoa significantly against controls. Vitamin E 50 mg/kgBW and 200 mg/kgBW significantly increased motility of spermatozoa (p<0.05) compared to those in the cisplatin group only. Vitamin E 50 mg/kgBW, and 200 mg/kgBW did not have a significant difference in spermatozoa motility compare to control groups. Vitamin E 50 mg/kgBW and 200 mg/kgBW could increase the spermatozoa morphology significantly compare to those cisplatin only group. Vitamin E 50 mg/kgBW, and 200 mg/kgBW did not have a significant difference in spermatozoa morphology compared to control groups. Conclusion: α-tocopherol 50 mg/kgBW and 200 mg/kgBW provided a same protective effect against spermatozoa damage especially in motility and morphology aspect due to cisplatin exposure. Therefore, in this study it was more recommended to use α-tocopherol in 50 mg/kgBW dose than 200 mg/kgBW.

Chronic Obstructive Pulmonary Disease (COPD) is a dangerous prevalent smoking-related disease characterized by abnormal inflammation and oxidative stress and expected to be the third cause of death in the world next decade. Corticosteroids have low effects in decreasing numbers of inflammatory mediators specifically in long-term use. Our study designed to investigate the possible protective effects of combined dexamethasone (Dex) (2mg/kg) and losartan (Los) (30mg/kg angiotensin receptor blocker, it possesses antioxidant and anti-inflammatory properties in lung injury in mice) against cigarette -smoke (CS) induced COPD in rats compared with dexamethasone and losartan. Male Sprague Dawley rats (N = 40) divided into five groups (n = 8): control group, CS group, Dex group, Los group, and Dex +Los group. COPD induced in rats by CS exposure twice daily for 10 weeks. After the specified treatment period, bronchoalveolar lavage fluid (BALF) and lung tissue were collected for measurement of SOD, NO, MDA, ICAM-, MMP-9, CRP, NF-κB and histopathology scoring. Our results indicated that Los+Dex significantly prevent CS-induced COPD emphysema, congested alveoli, and elevation of lung injury parameters in BALF. They also showed a significant decrease in MDA, ICAM-1, MMP-9, CRP, and NF-κB and a significant increase in SOD and NO. In conclusion, adding Los to Dex potentiating their activity in inhibition the progression of COPD based on its activity on oxidative stress, inflammation, and NF-κB protein expression.

AbstractObjectivesMethotrexate (MTX) is an anticancer drug used in chemotherapy. MTX was known for its toxic effects involving most of the organs including testis. Bee pollen is healthy food for human and has antioxidant effect. We intended to determine protective effect of bee pollen against testicular injury caused by MTX in rats.MethodsThirty-two adult Sprague Dawley male rats were used, and 4 groups were formed: control, MTX, pollen, and MTX + pollen. Rats were given pollen at a dose of 400 mg/kg with intragastric gavage for 10 days. On day 7, MTX was administered a single dose of 30 mg/kg ip. Serum testosterone and LH, tissue MDA level, and SOD and CAT enzyme activities were examined. In addition, spermatological parameters were evaluated.ResultsMDA level and SOD activity increased while testosterone level decreased significantly in the MTX group compared to the control group. In the MTX + pollen group, MDA level and SOD activity decreased while testosterone level increased. There was no significant change in CAT activity and LH values. Abnormal sperm ratio decreased in the MTX + pollen group compared to the MTX group.ConclusionsOur results suggest that bee pollen has a healing effect on reproductive parameters in testicular damage caused by MTX.
