Abstract
BACKGROUND Chlorogenic acid (CGA) is one of the well-known polyphenol compounds possessing several important biological and therapeutic functions. In order to optimize a culture system to achieve complete development of follicles, we focused on the effects of CGA supplementation during in vitro culture (IVC) on follicular development, oxidative stress, antioxidant capacity, developmental gene expression, and functional potential in cultured mouse ovarian tissue. METHODS AND RESULTS The collected whole murine ovaries were randomly divided into four groups: (1) non-cultured group (control 1) with 7-day-old mouse ovaries, (2) non-cultured group (control 2) with 14-day-old mouse ovaries, (3) cultured group (experimental 1) with the culture plates containing only the basic culture medium, (4) cultured group (experimental 2) with the culture plates containing basic culture medium + CGA (50, 100 and 200 µmol/L CGA). Afterward, histological evaluation, biochemical analyses, the expression assessment of genes related to follicular development and apoptosis as well as the analysis of 17-β-estradiol were performed. The results showed that supplementation of ovarian tissue with the basic culture media using CGA (100 µmol/l) significantly increased the survival, developmental and functional potential of follicles in whole mouse ovarian tissues after 7 days of culture. Furthermore, CGA (100 µmol/L) attenuated oxidative damage and enhanced the concentration of antioxidant capacity along with developmental gene expression. CONCLUSION It seems that supplementation of ovarian tissue with culture media using CGA could optimize follicular growth and development in the culture system.

Abstract
Background Testicular tissues could damage by ionizing radiation (IR) during the treatment of pelvic cancers. The aim of this study was to investigate both the protective and therapeutic effects of chlorogenic acid (CGA) on IR-induced mouse testis tissue damage. Methods In this experimental study, 70 mice were divided into 3 groups, including group 1 (normal saline), group 2 (IR + normal saline), and group 3 (IR + 5, 10, 20, 40, and 80 mg/kg) CGA via I.P injection. Animals in groups 2 and 3 received a dose of 2.0 Gy total-body irradiation in a single fraction. At two determined time points (16 h and 35 days after exposure), the testis and caudal part of both epididymis were isolated and underwent subsequent analyses. Results The results showed that irradiation of mice caused massive damage to spermatogenesis, seminiferous tubules, basal lamina, Leydig cells, and sperm parameters. Further biochemical assessment of the data demonstrated that 40 mg/kg CGA almost restored MDA to a normal level. In addition, the level of SOD, TAC, and GSH were significantly increased in the 40 mg/kg CGA treated group. Molecular evidence confirmed the protective effects of CGA and also revealed that the ratio of Bax/Bcl-2 in the presence of 40 mg/kg CGA was significantly decreased compared to IR and some treated groups. Conclusion The protective and therapeutic effects of CGA on testis were found to be positively correlated with the dose level.

Abstract
Skin flap necrosis has been remained as an unsolved problem in plastic and reconstructive surgeries. Here, we explored the effects of metformin post-treatment on random skin flap survival in rats. An 8.00 × 2.00 cm dorsal skin flap was created in 24 rats and they were then divided into three groups (n = 8) including Control, metformin (Met) 50.00 mg kg-1 and Met 100 mg kg-1. All animals were administrated orally until seven days after flap surgery. Flap survival, the number of blood vessels and mast cells in the flap tissues were analyzed. Vascular endothelial growth factor (VEGF) expression levels in flap tissues was also determined using immunohistochemical methods. The percentage of survival area in Met 50.00 mg kg-1 and Met 100 mg kg-1 groups were significantly higher compared to control. The blood vessel density and the VEGF positive cells in the viable areas of flaps showed a significant increase in Met 50.00 mg kg-1 group compared to control group. The results of this study suggested that treatment with metformin, especially with low dose following skin flap surgery was effective in improving the flap survival and increasing the neovascularization in the flaps tissues of rats.

Abstract
Polycystic ovarian syndrome (PCOS) is a complex endocrine and metabolic disorder. Chlorogenic acid (CGA) bears antioxidant properties with protective effects on different tissues. This study was conducted to evaluate the effect of CGA on follicular development, hormonal status and biomarkers of oxidative stress in a rat model of PCOS. In this experimental study, 18 rats were divided into three equal groups including: control, non-treated PCOS [(estradiol valerate (EV): 40.00 mg kg-1 intramuscularly)], and PCOS-CGA (EV: 40.00 mg kg-1 intramuscularly and CGA: 100 mg kg-1 intraperitoneally once a week for eight consecutive weeks). At the end of treatment period, all rats were anesthetized. Then 5.00 mL blood samples of rats in the three groups were taken and prepared for hormonal analyses and their ovaries were isolated and dissected mechanically free of fat and mesentery. The ovaries underwent the following analyses: Morphological study with Hematoxylin and Eosin staining and biochemical study using the malondialdehyde (MDA) level and total antioxidant activity. Data were analyzed using one-way ANOVA and post hoc Tukey's test. The serum level of luteinizing hormone, estrogen, testosterone, antioxidant capacity, glutathione and the number of cystic follicles in the PCOS group treated with 100 mg kg-1 Chlorogenic acid compared to the non-treated PCOS group were significantly decreased, however, the serum level of follicle stimulating hormone, progesterone, MDA and the number of secondary, graafian follicles and corpus luteum were significantly increased. Chlorogenic acid could be effective in ameliorating follicular development as well as hormonal and biochemical disorders in rats with PCOS.

Abstract
BACKGROUND Oxidative stress is a major contributor to diabetes, which can lead to testicular damage and infertility. OBJECTIVE This study aimed to compare the effects of metformin as a chemical drug with silymarin as an herbal agent on the sperm parameters and histopathological changes of testes in diabetic rats. MATERIALS AND METHODS Thirty-two male Wistar rats (250-270 gr) were randomly divided into four groups: 1) control; 2) diabetic; 3) diabetic+metformin 200 mg/kg; and 4) diabetic+silymarin 100 mg/kg. Daily injections were administered intraperitoneally for 56 days. At the end of the treatment, blood sampling was performed for biochemical assessment. Then, the rats were sacrificed and their left testis and epididymis were cut for sperm analysis as well as histopathology and morphometric evaluation. RESULTS Diabetes was associated with a reduced sperm count, motility, viability, maturity, and chromatin quality of sperm (p ≤ 0.001). It was also associated with a higher malondialdehide level and lower total antioxidant capacity level of serum in comparison with the control group (p ≤ 0.001). There was a significant difference in the seminiferous tubule diameter, germinal epithelium height, and testicular histopathological alterations in the diabetic rats compared with the control rats (p ≤ 0.001). Treatment with metformin and silymarin improved the above-mentioned parameters and this improvement was more substantial in silymarin-treated animals (p ≤ 0.001). CONCLUSION In diabetic rats, metformin and silymarin improved sperm parameters, sperm DNA integrity, seminiferous tubule diameter, germinal epithelium thickness, and testicular histopathological complications; this improvement was more substantial in the silymarin-treated group. So, the findings of this study suggest that silymarin is more effective than metformin in treating diabetic-induced infertility.

Abstract
Background Cerium oxide nanoparticles (CeO2 NPs) as an important nanomaterial have a wide range of applications in many fields and human beings' exposure to this nanomaterial is unavoidable. The effects of CeO2 NPs on the male reproductive system are controversial. Objective To determine the effects of the administration of CeO2 NPs on the testis tissue, sperm parameters, and in vitro fertilization (IVF) in mice. Materials and Methods Twenty-four male mice were divided into three groups (n = 8/each): one control and two experimental groups receiving CeO2 NPs at doses of 50 and 100 mg/kg body weight, respectively, for 35 days. At the end of the experiment, the diameter of seminiferous tubules (SNTs), epithelial height of SNTs, spermiogenesis index in testes, sperm parameters (count, motility, viability, and morphology), sperm chromatin condensation, DNA integrity, and IVF assays were analyzed. Results Histological results showed that the tubular diameter, the epithelial height of the SNTs, and the spermiogenesis index were significantly decreased in the experimental groups receiving CeO2 NPs. All sperm parameters in the experimental groups were significantly reduced and, additionally, the percentages of immature sperms and sperms with DNA damage were significantly increased in groups treated with CeO2 NPs compared to the control. Furthermore, the rates of IVF and in vitro embryo development were decreased. Conclusion Collectively, the current study showed that oral administration of CeO2 NPs in mice had detrimental effects on the male reproductive system through inducing testicular tissue alterations, decreasing sperm parameters quality, and also diminishing the IVF rate and in vitro embryonic development.

Abstract
Background: Aortic artery stenosis leads to Ischemia-Reperfusion (I-R) injury, which can cause certain clinical expressions, such as paraplegia. Objectives: To appraise the effect of Catechin Hydrate (CH) against spinal cord I-R injury. Materials & Methods: A total of 35 male rats (250-300 g) were divided randomly into five groups: intact, sham surgery, dimethyl sulfoxide (I-R+DMSO), low-dose CH (I-R+10 mg/kg CH), and high-dose CH (I-R+20 mg/kg CH). Abdominal aorta clamping was done for 60 min. Seventy-two hours after I-R, animals were evaluated for neurologic function, biochemical analysis, and histology. The data analysis was conducted by SPSS v. 16 using ANOVA and Kruskal-Wallis and Mann-Whitney U tests. Results: The mean Motor Deficit Index (MDI) score and white matter damage in the CH (20 mg/kg) group were lower than in the DMSO group (P=0.032). The mean plasma levels of malondialdehyde (MDA) and superoxide dismutase (SOD) in the CH groups were lower than that of the DMSO group (P<0.05). The plasma level of Total Antioxidant Capacity (TAC) in the CH (20 mg/kg) group was higher than in the DMSO group (P=0.032). In addition, the plasma level of catalase in the CH (20 mg/kg) group was higher than in the DMSO and CH (10 mg/kg) groups (P<0.001). The average number of normal motor neurons in the experimental groups was lower than in the sham surgery group (P<0.001).

Abstract
AIM To investigate the effect of Propolis-gum Arabic as a nerve guidance channel. MATERIAL AND METHODS Male rats (n=24) were randomly divided into sham surgery, autograft, and Propolis+gum Arabic groups with equal numbers. Under anesthesia, the sciatic nerve was removed, and the gap between the two ending was repaired by Propolis-gum Arabic or nerve autograft. Nerve regeneration was evaluated by sciatic function index (SFI), withdrawal reflex latency (WRL), muscle fiber diameter, number of myelinated axons, myelinated fiber diameter, and immunohistochemical analysis. RESULTS At 30, 49, 60 and 90 days after surgery, the mean of SFI in Propolis + gum Arabic group was significantly greater than the autograft group (p < 0.03). The mean muscle fiber diameters (30 and 90 days after surgery) and the mean number of myelinated axons (90 days after surgery) in Propolis + gum Arabic group were significantly greater than autograft group (p < 0.05). In addition, 90 days after surgery, the mean myelinated fiber diameter in Propolis + gum Arabic group was significantly higher than autograft group (p < 0.05). CONCLUSION The results of this study suggest that as guidance channel, the Propolis + gum Arabic may be useful in peripheral nerve regeneration.

Abstract
Background: This study investigated the potential effects of Titanium dioxide nanoparticles (Tio2NPs) followed by maternal gavage on fetal development and neural tube formation during pregnancy in mice. Methods: Thirty pregnant mice were randomly divided into five main study groups including the untreated control and 4 experimental groups (n=6 per group). The control group was treated with normal saline and the experimental groups were orally treated with doses of 30, 150, 300, and 500 mg/kg Body Weight (BW) of Tio2NPs during pregnancy. On gestational day 16 and 19 (n=3 per group), pregnant mice were euthanized and then examined for neural tube defects and compared with control. Serial transverse sections were prepared in both cranial region and in lumbar region of spinal cord. Results: Treatment with Tio2NPs resulted in low fetal weight and short length, dilation of lateral ventricle, thinning of cerebral cortex and spinal cord, spina bifida occulta and an increase in the number of apoptotic neurons in exposed embryos at doses of 300 and 500 mg/kg (p<0.05). Conclusion: It seems that exposure to nanoparticles of Tio2 during pregnancy induces growth retardation and for the first time, teratogenicity of this nanomaterial in neural tube development and induction of defects such as spinal bifida, reduction in cortical thickness and dilatation of lateral ventricles were verified which can be related to incidence of apoptosis in central nervous system.

Abstract
Humans are usually exposed to multiple pesticides in real life, but little is known as yet about the safety of low-dose pesticides mixtures. This study was conducted to evaluate the effects of long-term exposure to very low doses of pesticide mixtures on biochemical, histological, and neurobehavioral alterations in the rat model. For 90 days, four groups of male Wistar rats were given a mixture of five pesticides (in drinking water) in doses of 0, 0.25, 1 and 5 times the legally permitted levels (mg/kg body weight/day). After three-month exposure, the neurobehavioral effects of pesticide mixtures were evaluated by the Morris water maze, elevated plus maze and the open field tests. Then the biochemical and histopathological alterations in the hippocampus of studied animals were evaluated. Results showed that long-term exposure to a combination of five pesticides affected the nervous system in dose-dependent manner. As expected, nearly all of the parameters determined in this study were adversely changed in the high dose group. Exposure to medium dose (permitted level of pesticides mixture) was also able to induce oxidative stress and impaired memory and learning ability, although not all parameters were significantly changed in this group. It means that pesticides may behave differently when mixed. Interestingly, the administration of low doses of these chemicals induced an adaptive response by stimulating the redox system. In conclusion, it seems that the prolonged exposure to pesticide mixtures may cause adverse neurobehavioral effects, even at permitted levels.

Abstract
Titanium dioxide particles (TiO2) as the second most widely used materials in consumer products are composed of nano-sized (<100 nm) particles (NPs) and fine-sized (>100 nm) particles (FPs). Toxicological studies on animals have shown that TiO2 NPs exposure can cross the blood-testis barrier and accumulate in the testis resulting in testicular tissue damage and reduction of sperm count and motility. However, there is no information on the toxic effects of TiO2 FPs on male reproductive fertility. Twenty-four adult male mice were randomly divided into three groups including control, TiO2 NPs, and TiO2 FPs (150 mg kg-1 per day). After intragastric administration for 35 days, testicular tissue alterations (seminiferous tubule diameter and germinal epithelial height), sperm parameters (count, motility, viability, morphology, and DNA quality), in vitro fertilization potential, oxidative stress assays such as malondialdehyde (MDA) content, level of glutathione (GSH) and activities of superoxide dismutase (SOD) and glutathione peroxidase (GPx) in testicular tissue were investigated. The results showed that both sizes of TiO2 caused pathologic changes in the testis and significantly increased MDA level and decreased GSH levels and activities of SOD and GPx in testicular tissue. Moreover, the administration of both sizes of TiO2 significantly decreased all of the sperm parameters and in vitro fertility (fertilization rate and pre-implantation embryos development) compared to control. Administration of TiO2 FPs similar to TiO2 NPs through inducing damages to testis led to a marked reduction in sperm quality, in vitro fertilization, and embryos development in male mice.

Abstract
Background: The production of stress oxidative condition in body which is caused by consumption of ecstasy (3,4-methylenedioxymethamphetamine [MDMA]) leads to a liver damage. As an antioxidant, Vitamin E can protect cells and tissues against the deleterious effects of free radicals. This study evaluates the protective effects of Vitamin E on MDMA induced liver toxicity. Materials and Methods: Twenty-eight male albino mice were randomly assigned to four equal groups. Group 1 received saline (control), Group 2 received MDMA and saline, Group 3 received MDMA, and Vitamin E and Group 4 received Vitamin E. MDMA was injected with single daily dose, three sequential days/week for 5 weeks. At the end of the period, blood samples were collected for a biochemical analysis and then the mice were sacrificed by cervical dislocation for histopathological and biochemical examinations of liver. Results: The administration of Vitamin E attenuated the increased levels of alanine transaminase, aspartate transaminase, and alkaline phosphatase enzymes in serum. Vitamin E treatments significantly restored endogenous antioxidant enzymes (reduced glutathione and superoxide dismutase enzyme) activities as compared with MDMA-treated animals. Histological examination of liver revealed significant morphological tissue injuries in hepatocytes after MDMA being used, but in coadministration of vitamin E and MDMA, these morphological alterations reduced. Conclusion: The study showed that MDMA administration has adverse effects on the liver. Vitamin E lessened the deleterious impact considerably.

Abstract
Fluoxetine is a selective serotonin reuptake inhibitor is commonly prescribed to treat maternal depression in pregnancy and lactation. This study aimed to investigate the effects of maternal exposure to fluoxetine via lactation on testicular tissue, sperm parameters including count, motility, viability, and normal morphology and testicular oxidative stress status in male mice offspring. Ten mice dams were divided into control and experimental groups. The control group received water and the experimental group received fluoxetine (20.00 mg kg-1) by gavage daily from postnatal days of 0-21. Histology of testis, sperm parameters and oxidative stress in the testicular tissue were analyzed at 80 days after birth in their male offspring (n = 8). Significant reductions in the body and testes weights were observed in animals exposed to fluoxetine. Additionally, fluoxetine exposure significantly reduced all sperm parameters, tubular diameter and epithelial height of the seminiferous tubules as well as Leydig cells number. Significant increases in the testicular malondialdehyde levels and percentage of sperm with chromatin/DNA damage were observed in mice exposed to fluoxetine compared to control. These findings suggest that maternal exposure to fluoxetine during lactation in mice has a negative effect on the testicular tissue of their offspring and impairs the spermatogenesis process which in turn can induce infertility.

Abstract
AIM To evaluate the effect of different remote ischemic preconditioning (RIPC) methods in spinal cord ischemia-reperfusion (IR) injury. MATERIAL AND METHODS A total of 36 rats were distributed to the 6 groups: sham surgery, control (only spinal cord IR), unilateral (hind limb RIPC before spinal cord IR), bilateral (hind limbs RIPC before spinal cord IR), ipsilateral (hind and fore limbs RIPC to the right before spinal cord IR), contralateral (right hind limb and left fore limb as RIPC before spinal cord IR). Thirty minutes after RIPC, the spinal cord was subjected to ischemia for 60 minutes. Seventy two hours after IR, all rats were evaluated by neurological function, histological and biochemical examinations. RESULTS The mean Motor Deficit Index (MDI) scores in the ipsilateral, contralateral, and bilateral groups were lower than that of the unilateral group (p < 0.05). The mean malondialdehyde (MDA) in ipsilateral group was lower than were control group (p < 0.05). The mean total antioxidant capacity (TAC) and the mean number of normal motor neurons in the experimental groups were significantly higher than increased control group (p < 0.05). The mean plasma levels of catalase in the contralateral, ipsilateral, and bilateral groups were significantly increased compared to control group (p < 0.05). The mean scores of white matter damage in contralateral, bilateral, and unilateral groups were lower than control group (p < 0.05). CONCLUSION The results of this study show that contralateral, ipsilateral, and bilateral limb RIPC may reduce the complications of spinal cord ischemic injury.

Abstract
In this study, we investigated the potential of thymol and its mode of action to protect against the titanium dioxide (TiO2) nanoparticle-induced testicular damage. Twenty-four rats were randomly divided into four groups: control group, TiO2 (100 mg/kg BW/day) group, TiO2 + thymol (10 mg/kg BW/day) group, and TiO2 + thymol (30 mg/kg BW/day) group. With the exception of the control group, all animals received orally TiO2 nanoparticles for 60 days. In treatment groups, animals were given orally thymol 1 h before TiO2 nanoparticles. Epididymal sperm parameters, testicular histopathology, and spermatogenesis assessments were performed for evaluation of the TiO2 and thymol effects on the testis. Furthermore, antioxidative enzyme activities such as catalase (CAT), glutathione peroxidase (GPx) and superoxide dismutase (SOD), and malondialdehyde (MDA), glutathione (GSH) levels and ferric-reducing antioxidant power (FRAP) value were measured. Intragastric administration of TiO2 for 60 consecutive days caused a significant decrease in sperm quality, widespread histopathological alteration, and significantly induced oxidative stress as manifested by elevated MDA levels and a remarkable decline in antioxidant enzyme activities such as CAT, SOD, and GPx, and also FRAP and GSH levels in testis tissue. Nearly all of these alterations were significantly ameliorated in the groups that orally received thymol before TiO2 nanoparticles administration. The results of this study demonstrated that thymol improved the spermatogenesis defects induced by TiO2 nanoparticles in rats in a dose-dependent manner by protecting the testes against the testicular toxicity. Reduction in TiO2 nanoparticle-induced oxidative stress may have a major role in this protective effect.

Abstract
Previous studies proved the pro-angiogenic effect of Crocetin, a natural carotenoid dicarboxylic acid, in both in vivo and in vitro models. However, the exact mechanism of Crocetin action has not completely been elucidated yet. The current experiment was designed to find the activity of PI3K-Akt-eNOS axis after the treatment of endothelial cells with Crocetin in vitro. Human Umbilical Vein Endothelial Cells (HUVECs) were incubated with various concentrations of Crocetin (1, 5, 25, 50, and 100 µM) over a period of 72 h. Crocetin significantly increased HUVECs viability after 72 h as compared with the control group. We also found that Crocetin promoted the formation of the capillary-like structure compared to the control (p<0.05). Moreover, an improved migration rate and increased MMP-9 activity were observed in HUVECs that received 50 µM Crocetin (p<0.05). Crocetin enhanced the uptake of Ac-LDL which is correlated with increased lipid metabolism. Based on the data from the current experiment, protein level of VEGFR-1, -2 and p-Akt/Akt, p-eNOS/eNOS ratios were increased 72 h after the treatment of HUVECs with Crocetin (p<0.05). In contrast, the transcription level of VEGF was reduced in Crocetin-treated cells. These data demonstrated that Crocetin promotes HUVECs angiogenesis potential by the modulation of VEGF signaling pathway and increased cell viability. The PI3K/Akt/eNOS axis is required for a Crocetin-associated activity in endothelial cells.

Abstract
Background Phenylhydrazine (PHZ) induced anemia and was shown to have harmful effects on the male reproductive system. Objective To investigate the protective effect of vitamin C (Vit C) on sperm parameters quality, in vitro fertilization potential and embryonic development in a mouse model of hemolytic anemia induced by PHZ. Materials and Methods Thirty-two NMRI adult male mice (n = 8/each) were randomly classified into four groups. Group I (control) received normal saline, Group II (PHZ) received 8 mg/100 gr body weight PHZ as initial dose, continued by 6 mg/100 gr intraperitoneally every 48 hr, Group III (Vit C) received Vit C (10 mg/kg, daily, intraperitoneally), and group IV (PHZ + Vit C) received PHZ and Vit C. After 35 days, sperm quality parameters, the percentage of sperm with DNA damage and in vitro fertilization outcomes up to blastocyst stage were evaluated. Results A significant (p < 0.001) reduction in all of the sperm parameters (count, motility, viability and normal morphology) were observed in group II (PHZ) compared with group I (control). In group IV (PHZ ± Vit C), these parameters and sperm DNA damage (p < 0.001) improved significantly when compared with PHZ-treated mice. Furthermore, PHZ caused a significant (p < 0.001) decrease in the fertilization rate and the percentage of pre-implantation embryos' (two cell embryo and blastocyst) formation in comparison to group I (control), and Vit C supplementation in mice of group IV improved significantly the fertilization rate (p = 0.002), but it could not improve the percentage of two cell embryos and blastocyst production. Conclusion The data from this study indicated that Vit C decreased the adverse effects of PHZ on the quality of sperm parameters and in vitro fertilization rate, but it is insufficient to restore the in-vitro embryonic development and fertility potential.

Abstract
Previous studies have identified the heart as a source and a target tissue for oxytocin and relaxin hormones. These hormones play important roles in the regulation of cardiovascular function and repair of ischemic heart injury. In the current study, we examined the impact of oxytocin and relaxin on the development of cardiomyocytes from mesenchymal stem cells. For this purpose, mouse adipose tissue-derived stem cells (ADSCs) were treated with different concentrations of oxytocin or relaxin for 4 days. Three weeks after initiation of cardiac induction, differentiated ADSCs expressed cardiac-specific genes, Gata4, Mef2c, Nkx2.5, Tbx5, α- and β-Mhc, Mlc2v, Mlc2a and Anp, and cardiac proteins including connexin 43, desmin and α-actinin. 10 -7 M oxytocin and 50 ng/mL relaxin induced the maximum upregulation in the expression of cardiac markers. A combination of oxytocin and relaxin induced cardiomyocyte differentiation more potently than the individual factors. In our experiment, oxytocin-relaxin combination increased the population of cardiac troponin I-expressing cells to 6.84% as compared with 2.36% for the untreated ADSCs, 3.7% for oxytocin treatment and 3.41% for relaxin treatment groups. In summary, the results of this study indicated that oxytocin and relaxin hormones individually and in combination can improve cardiac differentiation of ADSCs, and treatment of the ADSCs and possibly other mesenchymal stem cells with these hormones may enhance their cardiogenic differentiation and survival after transplantation into the ischemic heart tissue.

Abstract
Operation on the thoraco-abdominal aorta may lead to paraplegia or paraparesis is after spinal ischemia/reperfusion (I/R) injury. In this study, we investigated the protective effect of the spinach extract on spinal cord I/R injury. Thirty-five male Sprague-Dawley rats were divided into five groups: Intact, sham surgery, normal saline (NS), low dose spinach extract (20 mg kg-1), high dose spinach extract (50 mg kg-1). Neurological function, biochemical and histological evaluations were performed in 72 hr after ischemia. The mean motor deficit index scores of the spinach extract groups were significantly lower than in the NS group at 72hr after spinal cord ischemia. In addition, Spinach extract groups significantly increased plasma level of total antioxidative capacity and decreased the plasma level of malondialdehyde than the NS group. The spinach extract groups displayed a significantly large number of normal motor neurons compared with the NS group. In conclusion, the present study showed that the spinach extract may preserve more neurons in a rat model of spinal cord I/R injury.

Abstract
BACKGROUND Titanium dioxide nanoparticle (TiO2NP) is commonly used in industrial products including food colorant, cosmetics, and drugs. Previous studies have shown that oral administration of TiO2NP can be toxic to the reproductive system, but little is known if TiO2NP could be able to affect the functions of the female reproductive system, in particular fertility. OBJECTIVE The objective was to evaluate the effects of oral administration of TiO2NP on histological changes in ovaries, pregnancy rate and in vitro fertility in mice. MATERIALS AND METHODS In this experimental study, 54 adult female NMRI mice were randomly assigned to two groups: control group (received vehicle orally) and TiO2NP group (received 100 mg/kg/daily TiO2NP solution orally). After 5 wk, pregnancy and in vitro fertilization rates, histological changes in ovaries, malondyaldehyde and estrogen hormone levels in the blood serum were investigated and compared between groups. RESULTS Our results revealed that TiO2NP administration induced histological alterations in ovary including, degenerating and reduction of ovarian follicles, ovarian cyst formation and disturbance of follicular development. Compared to control, animals in TiO2NP group have shown significant reduction of pregnancy rates and number of giving birth (p=0.04). TiO2NP caused significant reduction in oocyte number, fertilization rate, and pre-implantation embryo development (p<0.001). Furthermore, malondyaldehyde and estrogen hormone levels were significantly (p<0.01) increased in mice received TiO2NP. CONCLUSION Our findings suggest that TiO2NP exposure induces alterations on mice ovary resulting in a decrease in the rate of embryo development and fertility.

Abstract
Objective To explore the effects of pre versus post ischemic treatment with metformin after global cerebral ischemia in rats. Methods Male Wister rats underwent forebrain ischemia by bilateral common carotid artery occlusion for 17 min. Metformin (200 mg/kg) or vehicle was given orally by gavage for 7-14 days. Rats were divided into: control, metformin pre-treatment, metformin post-treatment and metformin pre and post continuous treatment groups. Cerebral infarct size, histopathology, myeloperoxidase and serum malondialdehyde were measured 7 days after ischemia. Results Histopathological analysis showed that metformin pre-treatment significantly decreased leukocyte infiltration, myeloperoxidase activity and also malondialdehyde level. Metformin pre-treatment and metformin post-treatment reduced infarct size compared with the control group, but it was not significant in the pre and post continuous treatment group. Conclusion Our findings suggest that pre-treatment with metformin in comparison with post-treatment in experimental stroke can reduce the extent of brain damage and is more neuroprotective at least in part by inhibiting oxidative stress and inflammation.

Abstract
The study was aimed to investigate the protective action of thymol against nano titanium dioxide (nano-TiO2) induced hepatotoxicity in rats. To achieve this purpose, the rats were divided into four groups (n = 6) including control, nano-TiO2 (100 mg/kg), nano-TiO2 + thymol (10 mg/kg) and nano-TiO2 + thymol (30 mg/kg). Intragastric (IG) administration of nano-TiO2 for 60 consecutive days caused widespread histological changes and significantly induced oxidative stress in the liver tissues as manifested by the rise in serum transaminase activities accompanied by marked decline of enzymatic (catalase, superoxide dismutase and glutathione peroxidase) and non-enzymatic (ferric reducing antioxidant power and glutathione) antioxidant levels, and rise of malondialdehyde levels in liver tissue. Pretreatment with thymol (IG) prior to nano-TiO2 administration significantly ameliorated all of biochemical and histopathological alterations in a dose-dependent manner. In conclusion, thymol effectively protects against nano-TiO2-induced hepatotoxicity in rats by its antioxidant properties.

Abstract
Many studies have found that stress during pregnancy is linked to an increased incidence of epileptic behaviors and reproductive disorders. However, few works have investigated the effect of pregestational stress on seizure susceptibility in the offspring. We investigated the effect of pregestational stress on epileptic behaviors in the offspring as well as fertility rate in dams. The male and female rats were randomly divided into four groups to form a combination of control and stressed groups for each sex. The rats were subjected to predatory stress (exposed to a cat) twice per day for 50 (male) and 15 (female) consecutive days. At the end of the stress procedure, the rats were coupled as follows: both male and female control (MC-FC), male stressed/female control (MS-FC), male control/female stressed (MC-FS), and both male and female stressed (MS-FS). Then, the puppies born from these groups were counted and evaluated for pentylentetrazole (PTZ)-induced seizure. There was no significant difference between the male and female pups in each identical group in terms of litter size and epileptic behaviors, except duration of tail rigidity and duration of immobility. The total score of seizure increased in all the stressed groups, but more severely in the MS-FS group. However, the onset of the first epileptic behavior and tonic-clonic seizure significantly decreased in the stressed groups. Moreover, fertility rate significantly decreased in the stressed groups compared with the control group, but there was no significant difference in terms of litter size between the groups. These data revealed the impact of pregestational stress during spermatogenesis and oogenesis on fertility rate in dams and epileptic behaviors in the offspring.

Abstract
Ag2 S@CdS core-shell particles were synthesized with different Cd source content as a measure of shell thickness using a pulsed microwave irradiation method. The particles were verified structurally using X-ray diffraction, energy dispersive X-ray analysis and transmission electron microscopy. Optical spectroscopy revealed that core-shells show an absorption peak at 750 nm and an emission peak located around 800 nm after 6 min of microwave irradiation. With continued microwave treatment, the NIR luminescence first vanished but it was revived after 12 min of irradiation, which was 100 nm red shifted. This new type of NIR emission in Ag2 S with sizes greater than 5 nm is due to the proximity of a highly deficient CdS shell with strong red emission that was stable for more than 6 months in water. A mechanism has been suggested for this type of emission.

Abstract
Congenital adrenal hyperplasia (CAH) is an inherited autosomal recessive enzymatic disorder involving the synthesis of adrenal corticosteroids. 21-Hydroxylase deficiency (21-OHD) is the most common form of the disease which is observed in more than 90% of patients with CAH. Early identification of mutations in the genes involved in this disease is critical. A marker of the disease, errors in the CYP21A2 gene, is thought to be part of the pathophysiology of CAH. Therefore, the identification of gene mutations would be very beneficial in the early detection of CAH. This research was a descriptive epidemiological study conducted on individuals elected by the inclusion criteria whom were referred to the Genetic Diagnosis Center of Tabriz during 2012 to 2013. After sampling and DNA extraction, PCR for the detection of mutations in the CYP21A2 gene was performed followed by sequencing. For data analysis, the results of sequencing were compared with the reference gene by blast, Gene Runner and MEGA-5 software. Obtained changes were compared with NCBI databases. The analysis of the sequencing determined the mutations located in Exons 6, 7, 8 and 10. The most frequent findings were Q318X (53%) and R356W (28%). Exon 6 cluster (7%), E431k (4%), V237E (2%), V281L (2%), E351K (2%), R426C (2%) were also frequent in our patients. The most frequent genotype was compound heterozygote, Q318X/R356W. Three rare mutations in our study were E431K, E351K and R426C. Observed mutation frequencies in this study were much higher than those reported in previous studies in Iranian populations. Thus, it seems that it is necessary to follow-up screening programs and use sequencing methods to better identify mutations in the development of the disease.

Abstract
BACKGROUND Dysmorphology and dysfunction caused by prenatal ethanol consumption in different organs of the offspring are wellknown phenomena. The objective of the present study was to explore the antioxidant effect of vitamin E supplementation on testis damage induced by maternal ethanol consumption during pregnancy and early postnatal days. METHODS Pregnant Wistar rats on gestation day 7 were assigned to 3 groups, namely, control, ethanol and ethanol-vitamin E groups. Ethanol-treated rats received 4.5 g/kg BW ethanol once per day from day 7 and the procedure continued through postnatal day 21. Vitamin E group received 300 mg of vitamin E and the same amount of ethanol. The male offspring from each group were anesthetized by 10% chloral hydrate (0.5 ml/kg body weight) on day 21 and 90 (n=8 offspring form each group on day 21 and day 90). The results were analyzed by one-way ANOVA. A p<0.05 was considered significant. RESULTS The results revealed significant (p<0.05) changes in oxidative stress parameters, luteinizing hormone and follicle-stimulating hormone, as well as testis structural alteration in offspring of ethanol group after 21 and 90 days of birth as compared to the control. Significant amelioration of changes in testis structure, along with restoration of the elevated level of oxidative stress parameters were found in vitamin E-treated animals. CONCLUSION The findings revealed that prenatal and postnatal ethanol-induced toxicity in testis was exerted through oxidative stress and implied that these effects could be alleviated by vitamin E as an antioxidant.

Abstract
OBJECTIVE(S) The aim of this study was to evaluate the final outcome of nerve regeneration across the eggsell membrane (ESM) tube conduit in comparison with autograft. MATERIALS AND METHODS Thirty adult male rats (250-300 g) were randomized into (1) ESM conduit, (2) autograft, and (3) sham surgery groups. The eggs submerged in 5% acetic acid. The decalcifying membranes were cut into four pieces, rotated over the teflon mandrel and dried at 37(°)C. The left sciatic nerve was surgically cut. A 10-mm nerve segment was cut and removed. In the ESM group, the proximal and distal cut ends of the sciatic nerve were telescoped into the nerve guides. In the autograft group, the 10 mm nerve segment was reversed and used as an autologous nerve graft. All animals were evaluated by sciatic functional index (SFI) and electrophysiology testing. RESULTS The improvement in SFI from the first to the last evalution in ESM and autograft groups were evaluated. On days 49 and 60 post-operation, the mean SFI of ESM group was significantly greater than the autograft group (P< 0.05). On day 90, the mean nerve conduction velocity (NCV) of ESM group was greater than autograft group, although the difference was not statistically significant (P> 0.05). CONCLUSION These findings demonstrate that ESM effectively enhances nerve regeneration and promotes functional recovery in injured sciatic nerve of rat.

Abstract
Endothelial progenitor cells circulating in the peripheral blood (PB) contribute to vascular repair. This study aimed to evaluate the potential of a 'cocktail' consisting of erythropoietin, granulocyte colony-stimulating factor and tetrahydrobiopterin to mobilize hematopoietic lineage negative/vascular endothelial growth factor receptor 2 positive (Lin(-)/VEGF-R2(+)) cells from the bone marrow (BM) to PB in non-diabetic and diabetic mice. Diabetes was induced in mice by intraperitoneal injection of streptozotocin. Diabetic mice were studied after 16weeks of hyperglycemia. Half the mice in each group (non-diabetic and diabetic) received daily intraperitoneal injections of the cocktail for 6 consecutive days while the other half received vehicle buffer. Mobilization of Lin(-)/VEGF-R2(+) cells, which were expanded in MCP301 medium, was evaluated after isolating them from BM and PB and their phenotypic and morphological properties were studied. We found that 16weeks of diabetes affected neither the total number of BM mononucleated cells nor the number of Lin(-)/VEGF-R2(+) cells in BM compared with non-diabetic controls. In non-diabetic mice, cocktail treatment resulted in a significant decrease in BM Lin(-)/VEGF-R2(+) cells, paralleled by a significant increase of these cells in PB. Such changes in the number of Lin(-)/VEGF-R2(+) cells in BM and PB after the cocktail treatment were less marked in diabetic mice. In vitro studies of BM Lin(-)/VEGF-R2(+) cells from diabetic and non-diabetic mice did not reveal any differences in either phenotypes or colony forming potential. These findings indicate that diabetes impairs the mobilization of Lin(-)/VEGF-R2(+) cells from BM to PB. Impaired mobilization of BM Lin(-)/VEGF-R2(+) cells soon after the onset of diabetes may contribute to complications such as diabetic retinopathy.

Abstract
The present study was designed to evaluate the effect of Vitamin E (Vit. E) on diabetes-induced changes in small intestine, lipid peroxidation and plasma antioxidant capacity in rats. Twenty-four rats were divided into three groups (n=8), namely control, non-treated diabetic (NTD) and Vit. E-treated diabetic (VETD) groups. The VETD group received 300 mg of Vit. E daily in drinking water. After 6 weeks, the length and weight of small intestine, villus height, crypt depth and muscular layer thickness showed a significant increase in the NTD group compared to the control group. In the VETD group, these parameters did not show any significant difference compared to the control group. The level of malondialdehyde (MDA) in the red blood cells showed a significant increase in the NTD group, but not in the VETD group, compared to the control group. The plasma antioxidant capacity showed a significant increase in VETD compared to the NTD group. These findings indicate that Vit. E significantly improved small intestinal changes in diabetic rats and that these effects could be mediated at least in part by enhanced plasma antioxidant capacity and reduced lipid peroxidation.
