Background: Generation of free radicals and oxidative stress are a major contributorto diabetes. These factors lead to the development of diabetic testicles disorders.Objective: In this study, the protective effect of vitamin E on functional disordersassociated with diabetes induced oxidative stress in male reproductive systems hasbeen investigated.Materials and Methods: Thirty-three adult male Mice were divided into control,diabetic, and untreated diabetic groups. Streptozotocin was used to induce diabetes.In the treated group, vitamin E was given to the Mice intraperitoneally for 30 days.Then, animals were anesthetized and sacrificed. Animal testicles were isolated andhomogenized in phosphate buffer and used for measuring sperm count, motility andsurvival of sperm, MDA concentration and antioxidant capacity (TAC). Apoptosis wasalso performed with the TUNEL test.Results: The results of reduction (12.03±98.11) TAC, MDA concentration (–28.5±2.58),sperm motility (unstable sperma= 86.4±7.48), sperm count (171.51), Sperm morphology(natural morphology= 49.69±31.93) and abnormal morphology (9.77±49.7)with increased oxidative damage. These changes were statistically significant incomparison with the control group for all variables other than MDA (p= 0.05). Treatmentof vitamin E diabetic Mice improved the ability of antioxidants to prevent oxidativedamage in the testicles, restore the sperm movement, and increase the number ofnormal sperm as well as TAC. The level of apoptosis in the treated group has decreasedcompared to the untreated group.Conclusion: Vitamin E protects the reproductive system against diabetes mellitus.Therefore, it was concluded that vitamin E may be a suitable agent for protecting thesperm and testicular parameters against undesirable effects of diabetes.

Progesterone (a neurosteroid) is an important modulator of the nervous system functioning. Organophosphorus pesticides like phosphamidon have been shown to adversely affect memory and induce oxidative stress on both acute and chronic exposure. The present study was therefore designed to investigate the effects of progesterone (PROG) on phosphamidon-induced modulation of cognitive function and oxidative stress in rats. Cognitive function was assessed using step-down latency (SDL) on a passive avoidance apparatus and transfer latency (TL) on an elevated plus maze. Oxidative stress was assessed by examining the levels of thiobarbituric acid reactive species (TBARS) and non-protein thiols (NP-SH) in isolated homogenized whole brain samples. The results showed a significant reduction in SDL and prolongation of TL in the phosphamidon (1.74 mg/kg/d; p.o.) treated group at weeks 6 and 8 as compared to the control group. Two weeks treatment with PROG (15 mg/kg/d; i.p.) antagonized the effect of phosphamidon on SDL as well as TL. Phosphamidon alone produced a significant increase in the brain TBARS levels and decrease in the brain NP-SH levels. Treatment with PROG (15 mg/kg/d; i.p.) attenuated the effect of phosphamidon on oxidative stress. Together, the results showed that progesterone attenuated the cognitive dysfunction and increased oxidative stress induced by phosphamidon in the brain.

Aim: Manganese (Mn) is an essential trace element in many cellular processes. However, there is dearth of literature on its influence on indomethacin-induced hepatorenal damage. Therefore, this study was conducted to investigate the effect of manganese on indomethacin-induced hepatorenal damage in rats. Methods: Rats were divided into four groups of eight rats consisting of control group, indomethacin (IND) alone (20 mg/kg), Mn alone (10 mg/kg) and co-treated group that were treated orally for 14 consecutive days. Twenty four hours after treatment, under pentobarbital anesthesia, blood was collected and liver was excised to prepare homogenate and histology staining. Liver and kidney function tests aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma glutamyl transferase (GGT), lactate dehydrogenase (LDH), malate dehydrogenase (MDH), glutamine dehydrogenase (GLDH), sorbitol dehydrogenase (SDH), glucose-6-phosphate dehydrogenase (G6PD), bilirubin (BIL), urea, creatinine, cholesterol (CHOL), triglycerides (TG), low and high density lipoprotein (LDL and HDL), electrolytes and oxidative stress superoxide dismutase (SOD), catalase (CAT), glutathione (GSH) and lipid peroxidation (LPO) biomarkers were assessed. Results: The results showed that indomethacin caused hepatorenal damage in rats manifested with increase in serum hepatic and renal function biomarkers. But co-administration of IND with Mn significantly (p < 0.05) decreased the level of hepatorenal biomarkers. Additionally, co-administration of IND with Mn improved the antioxidant status with concomitant reduction of LPO and restored the integrity of the liver and kidney histologically. Conclusion: The results of this study emphasize that co-administration of IND with Mn to rats alleviated IND-induced hepatorenal toxicities and oxidative stress in rats.

The present study was carried out to determine the effects of sub-chronic thinner addiction on the oxidant-antioxidant balance and oxidative stress on certain tissues and the possible protective effect of safranal against thinner toxication in rats. Adult male Wistar albino rats were randomly divided into four groups of 10 animals each as follows: control (C), safranal (S), thinner (T) and thinner+safranal (T+S). The control group received 1cc saline by gastric gavage. Safranal was administered to S and T+S groups by using gastric gavage at a dose of 100 mg/kg/day and volume of 0.1 mL/kg/day. Thinner inhalation was applied to T and T+S groups in a container with NaOH tablets twice a day. Levels of malondialdehyde (MDA), reduced glutathione (GSH), nitric oxide (NOx) metabolites, total antioxidant capacity (TAS) and total oxidant capacity (TOS) were determined in liver, lung, brain, kidney and testis tissues of the rats. In the T+S group, it was observed that the MDA levels significantly decreased in all tissues, except the kidney, in comparison to the thinner inhalation group (p = 0.000). When the NOx levels of the T+S group were compared with the levels of the T group, it was concluded that there existed a statistically significant decrease in the NOx levels in alltissues (p = 0.000). In T+S group, it was observed that safranal either eliminated or mitigated oxidative stress that developed in tissues through decreasing MDA and TOS levels and increasing GSH and TAS levels and caused significant decreases in NOX levels in all tissues. As a result, it was determined that safranal, although not uniform for all tissue types, had a protective potential against the damaging effects of oxidative stress caused by sub-chronic thinner inhalation.

The testis is an immunologically privileged organ. Sertoli cells can form a blood-testis barrier and protect sperm cells from self-immune system attacks. Spermatogenesis may be inhibited by severe illness, bacterial infections and chronic inflammatory diseases but the mechanism(s) is poorly understood. Our objective is to help in understanding such mechanism(s) to develop protective agents against temporary or permanent testicular dysfunction. Lipopolysaccaride (LPS) is used as a model of animal sepsis while L-carnitine (LCR) is used as a protective agent. A total of 60 male Swiss albino rats were divided into four groups (15/group). The control group received Saline; the 2ndgroup was given LCR (500 mg/kg i.p, once). The third group was treated with LPS (5 mg/kg i.p once) and the fourth group received LCR then LPS after three hours. From each group, five rats were used for histopathological examination. Biochemical parameters were assessed in the remaining ten rats. At the end of the experiment, animals were lightly anaesthetized with ether where blood samples were collected and testes were dissected on ice. Sperm count and motility were evaluated from cauda epididymis in each animal. Also, oxidative stress was evaluated by measuring testicular contents of reduced glutathione (GSH), malondialdehyde (MDA) and 8-hydroxydeoxyguanosine (8-HDG, the DNA adduct for oxidative damage) in testicular DNA. The pro-inflammatory mediator nitric oxide (NO) in addition to lactate dehydrogenase (LDHx) isoenzyme-x activity as an indicator for normal spermatozoal metabolism were assessed in testicular homogenate. Serum interlukin (IL)-2 level was also assessed as a marker for T-helper cell function. The obtained data revealed that LPS induced marked reductions in sperm's count and motility, obstruction in seminiferous tubules, hypospermia and dilated congested blood vessels in testicular sections concomitant with decreased testicular GSH content and LDHx activity. Moreover, the testicular levels of MDA, 8-HDG (in testicular DNA) and NO as well as serum IL-2 level were increased. Administration of LCR before LPS returned both sperm count and motility to normal levels. Also, contents of testicular GSH, MDA, 8-HDG and NO returned back to the corresponding control values. In addition, serum IL-2 level as well as histological abnormalities were markedly improved in LCR + LPS-treated rats. In conclusion, LPS increased proinflammatory and oxidative stress markers in the testis leading to a marked testicular dysfunction. L-carnitine administration ameliorates these effects by antioxidant and/or anti-inflammatory mechanisms suggesting a protective role against male infertility in severely infected or septic patients.

Abstract Background: Oxidative stress has previously been shown to play critical roles in the development of diabetes and its complications. The purpose of this research was to observe the reno-protective effect of metformin and its effect on oxidative stress in type 2 diabetic mice renal tissue.Methods: Type 2 diabetes mellitus mice model was established by High-fat feed combined with small-dose STZ and randomly divided into diabetes model group, Metformin [MET, 250mg/(kg.d)] group, Glibenclamide (GLIB) [GLIB, 2.5mg/(kg.d)] group, and normal control group (NC). After 8 weeks of intervention, blood and urine samples were collected for detection of FBG, HbA1c, urine albumin (Alb), retinol-binding protein (RBP), podocalyxin (PCX), 8-OHdG, 8-iso-PG, and creatinine (Cr). Renal tissue specimens were preserved for observing renal glomerular basement membrane thickness (GBMT) and foot process fusion rate (FPFR) under electron microscopy.Results: Compared with the NC group, FBG, HbA1c, urinary Alb/Cr (UACR), RBP/Cr (URCR), PCX/Cr (UPCR), 8-OHdG /Cr (UOHCR), and 8-iso-PG /Cr (UISOCR) significantly increased in the T2DM group (P <0.05). Compared with the T2DM group, FBG, HbA1c, UACR, URCR, UPCR, UOHCR, and UISOCR were significantly reduced in the GLIB group and MET group (P <0.05). Compared to the GLIB group, UACR, URCR, UPCR, UOHCR, and UISOCR decreased in the MET group (P <0.05), but FBG and HbA1c were not differenced statistically between the two groups. GBMT and FPFR increased in the T2DM group (P <0.05), which were reduced in the MET group and lighter than those in the GLIB group (P <0.05).Conclusion: Metformin intervention can play a reno-protective effect in type 2 diabetic mice, which may be related to its effect in inhibiting enhanced oxidative stress in vivo.

Methamphetamine (MA) leads to cardiac and pulmonary toxicity expressed as increases in inflammatory responses and oxidative stress. However, some interactions may exist between oxidative stress and endoplasmic reticulum stress (ERS). The current study is designed to investigate if both oxidative stress and ERS are involved in MA-induced chronic pulmonary toxicity and if antioxidant tertiary butylhydroquinone (TBHQ) alleviated ERS-apoptosis and oxidative stress by PERK-Nrf2 crosstalk. In this study, the rats were randomly divided into control group, MA-treated group (MA), and MA plus TBHQ-treated group (MA + TBHQ). Chronic exposure to MA resulted in slower growth of weight and pulmonary toxicity of the rats by increasing the pulmonary arterial pressure, promoting the hypertrophy of right ventricle and the remodeling of pulmonary arteries. MA inhibited the Nrf2-mediated antioxidative stress by downregulation of Nrf2, GCS, and HO-1 and upregulation of SOD2. MA increased GRP78 to induce ERS. Overexpression and phosphorylation of PERK rapidly phosphorylated eIF2α, increased ATF4, CHOP, bax, caspase 3, and caspase 12, and decreased bcl-2. These changes can be reversed by antioxidant TBHQ through upregulating expression of Nrf2. The above results indicated that TBHQ can alleviate MA-induced oxidative stress which can accelerate ERS to initiate PERK-dependent apoptosis and that PERK/Nrf2 is likely to be the key crosstalk between oxidative stress and ERS in MA-induced chronic pulmonary toxicity.

Background: Some plants stimulate spermatogenesis and increase fertility, while some cause spermatogenesis arrest. So far, the effects of bene (Pistacia atlantica) on male fertility have not been studied. The aim of this study was to investigate the effects of bene on sperm parameters, testicular histopathology, sperm quality, and oxidative stress in busulfan-induced infertile mice. Methods: Thirty-five male BALB/c mice were randomly assigned to control, sham, busulfan, bene, and bene + busulfan groups. The busulfan group received 10 mg/kg as a single dose and intraperitoneally. The bene group received pellets containing 10% of bene. Another group received 10 mg/kg busulfan and was fed with pellet containing 10% bene. Then, sperms, sperm chromatin quality, testicular histopathology, and oxidative stress levels were studied on the 35th day of the experiment. Results: Busulfan injection resulted in a significant reduction in sperm parameters compared to the control group (p<0.001); it decreased after bene administration (p<0.001). In addition, in the group treated with bene, the sperm count with damaged DNA was reduced and the level of malondialdehyde decreased compared to the busulfan group. A significant increase was observed in the mean level of superoxide dismutase and catalase enzymes in the bene + busulfan group compared to the busulfan group (p<0.001). The histopathological improvement of the testis was observed in the bene + busulfan group. Conclusion: The administration of 10 mg/kg of bene powder for 35 days reduced the oxidative stress, improved testicular histopathology, sperm chromatin quality, and sperm parameters in the infertile mice model.

A 2 × 2 factorial experiment (10 boars per treatment) was conducted for 16 weeks to evaluate the effects of the dietary n-6 : n-3 ratio (14 : 1 vs 6 : 1) and vitamin E (200 vs 400 mg kg–1) on boar sperm morphology and oxidative stress. Sperm mitochondrial membrane potential (MMP), reactive oxygen species (ROS), DNA damage (8-hydroxydeoxyguanosine; 8-OHdG), seminal lipoperoxidation (malondialdehyde; MDA) and antioxidant capacity in the serum, spermatozoa and seminal plasma were assessed as indicators of oxidative stress. Sperm production was similar among groups but increased (P < 0.05) throughout the 16 weeks of the study. Although sperm α-tocopherol content, ROS and seminal MDA did not differ between the two dietary n-6 : n-3 ratio treatments, enhanced antioxidant enzyme activity and MMP, but decreased 8-OHdG, were found in spermatozoa from boars consuming the 6 : 1 diet. The diet with the 6 : 1 ratio positively affected sperm morphology at Weeks 12 and 16 (P < 0.05). The α-tocopherol content and antioxidant capacity increased in boars with increasing levels of vitamin E supplementation. Compared with low-dose vitamin E, high-dose vitamin E supplementation improved sperm morphology. Overall, the results indicate that an n-6 : n-3 ratio of 6 : 1 and 400 mg/kg vitamin E have beneficial effects on sperm morphology by improving antioxidative stress.
