Abstract Cadmium (Cd) is one of the major toxicants, which affects human health through occupational and environmental exposure. In the current study, we evaluated the protective effects of morel mushrooms against Cd-induced reproductive damages in rats. For this purpose, 30 male rats were divided into 6 groups (n=5/group), the first group served as the control group, second group was treated with an intraperitoneal (i.p) injection of 1 mg/kg/day of Cd. Third and fourth groups were co-treated with 1 mg/kg/day of Cd (i.p) and 10 and 20 mg/kg/day of morel mushroom extract (orally) respectively. The final 2 groups received oral gavage of 10 and 20 mg/kg/day of morel mushroom extract alone. After treatment for 17 days, the animals were euthanized, and testes and epididymis were dissected out. One testis and epididymis of each animal were processed for histology, while the other testis and epididymis were used for daily sperm production (DSP) and comet assay. Our results showed that Cd and morel mushrooms have no effect on animal weight, but Cd significantly decreases the DSP count and damages the heritable DNA which is reversed in co-treatment groups. Similarly, the histopathological results of testes and epididymis show that morel mushrooms control the damage to these tissues. Whereas the morel mushroom extract alone could enhance the production of testosterone. These results conclude that morel mushrooms not only control the damage done by Cd, but it could also be used as a protection mechanism for heritable DNA damage.

Abstract The current study explored the beneficial effects of GA against testis and epididymis toxicity induced by CP treatment. Male rats were into 4 groups (n=7). Control (saline, intraperitoneal), Cisplatin (a single dose of 8 mg/kg/day cisplatin, intraperitoneal), Gallic acid (50 mg/kg Gallic acid orally for 10 days) and Cisplatin+Gallic acid groups. Total number of spermatogonia, Sertoli, Leydig cell and the total volume of testis, seminiferous tubule, interstitial area, and germinal epithelial thickness and numerical densities of caspase-3, Bax, Bcl-2, 8-OHdG immunopositive cells were calculated. Histopathological examination of the testis and epididymis was performed. MDA and CAT levels are measured in the testis. Also, the testosterone level was measured in the serum of the rats. As a result, a significant decrease was observed in all stereological data, Bcl-2 immunopositive cell number, CAT, and serum testosterone levels in the testis compared to the CP group control group, while a significant increase was observed in the number of caspase-3, Bax, and 8-OHdG immunopositive cells and the level of MDA. However, GA significantly improved these parameters. Our study reveals that GA may improve CP-induced male reproductive toxicity by reducing oxidative stress, suppressing apoptosis and DNA damage, and restoring structural and functional deterioration.

This study investigated the protective effects of vanillin against acute brain damage induced by carbon tetrachloride (CCl4) in rats. The study was performed on 32 male rats divided into four groups: a control group, vanillin group ([Va] 150 mg/kg/day, intraperitoneally [i.p.]) and CCl4 toxication groups received a single injection of CCl4 (1 ml/kg, i.p.; CCl4 and Va + CCl4 groups). The degree of protection in brain tissue was evaluated by the levels of malondialdehyde (MDA), glutathione (GSH), superoxide dismutase, glutathione transferase, glutathione peroxidase and nitric oxide (NO). Vanillin showed a significant brain-protective effect by decreasing the level of lipid peroxidation and NO2 and elevated the activities of antioxidative enzymes and level of GSH. Consequently vanillin blocked oxidative brain damage induced by CCl4 in rats.

Objective. The aim of this study was to investigate protective effects of resveratrol, a strong antioxidant, against possible negative effects of chronic immobilization stress on testes of male rats histochemically, immunohistochemically, ultrastructurally, and biochemically. Material and Methods. Male Wistar rats were divided into 4 groups (n=7). Group I, control group (C), was not exposed to stress. Group II, stress group (S), was exposed to chronic immobilization stress. In Group III, low dose resveratrol + stress group (LRS), rats were given 10 mg/kg/day resveratrol just before the stress application. In Group IV, high dose resveratrol + stress group (HRS), rats were given 20 mg/kg/day resveratrol just before the stress application. For chronic immobilization stress application animals were put in the plastic tubes (6 cm in diameter, 15 cm in length) during 32 days for 6 hours. All animals were sacrificed 18 hours after the last stress application. Results. Histochemical and ultrastructural investigations showed that in stress group there was germ cell deprivation in seminiferous tubules and increase of connective tissue on interstitial area. No significant changes were seen in low and high dose resveratrol groups. After immunohistochemical investigations, TUNEL (+) and Active Caspase-3 (+) cells were increased in seminiferous tubules of stress group compared with those control group, but they were decreased in low and high dose resveratrol groups. According to biochemically results, MDA, GSH, and testosterone levels in stress group showed no significant difference when compared with those of the other groups. Conclusion. The chronic immobilization stress increases oxidative stress and apoptosis and causes histological tissue damages; resveratrol can minimize the histological damage in testes significantly.

This study investigated the reproductive toxicity of methylmercury (MeHg) and Aroclor (Sigma-Aldrich), alone or in combination, following exposure of prepubertal male rats considering the chromatoid body (CB) as a potential target. The CB is an important molecular regulator of mammalian spermatogenesis, primarily during spermatid cytodifferentiation. Male Wistar rats were exposed to MeHg and/or Aroclor , according the following experimental design: control group, which was administered in corn oil (vehicle) only; MeHg-treated group, which was administered 0.5mg kg−1 day−1 MeHg; Aroclor-treated group, which was administered 1mg kg−1 day−1 Aroclor; Mix-LD, group which was administered a low-dose mixture of MeHg (0.05mg kg−1 day−1) and Aroclor (0.1mg kg−1 day−1); and Mix-HD group, which was administered a high-dose mixture of MeHg (0.5mg kg−1 day−1) and Aroclor (1.0mg kg−1 day−1). MeHg was diluted in distilled water and Aroclor was made up in corn oil (volume 1mL kg−1). Rats were administered the different treatments from PND23 to PND53 by gavage, . The morphophysiology of CBs was analysed, together with aspects of steroid hormones status and regulation, just after the last treatment on PND53. In addition, the long-term effects on sperm parameters were assessed in adult animals. MeHg exposure increased mouse VASA homologue (MVH) protein levels in seminiferous tubules, possibly affecting the epigenetic status of germ cells. Aroclor produced morphological changes to CB assembly, which may explain the observed morphological defects to the sperm flagellum and the consequent decrease in sperm motility. There were no clear additive or synergistic effects between MeHg and Aroclor when administered in combination. In conclusion, this study demonstrates that MeHg and Aroclor have independent deleterious effects on the developing testis, causing molecular and morphological changes in CBs. To the best of our knowledge, this is the first study to show that CBs are targets for toxic agents.

AbstractNicotine is one of the psychostimulant agents displaying parasympathomimetic activity; the chronic neurochemical and behavioral effects of nicotine remain unclear. Exercise lowers stress and anxiety and can act as a non-pharmacologic neuroprotective agent. In this study, the protective effects of exercise in nicotine withdrawal syndrome-induced anxiety, depression, and cognition impairment were investigated.Seventy adult male rats were divided randomly into five groups. Group 1 served as negative control and received normal saline (0.2 mL/rat, i.p.) for 30 days, whereas group 2 (as positive control) received nicotine (6 mg/kg/day, s.c.) for the first 15 days. Groups 4, 5, and 6 were treated with nicotine (6 mg/kg/day, s.c.) for the first 15 days and then were treated with forced exercise, bupropion (20 mg/kg/day, i.p.), or a combination of the two for the following 15 days. Between day 25 and day 30, Morris water maze was used to evaluate spatial learning and memory. From days 31 to 35, the elevated plus maze (EPM), open field test (OFT), forced swim test (FST), and tail suspension test (TST) were used to investigate the level of anxiety and depression in the subjects.Nicotine-dependent animals indicated a reflective depression and anxiety in a dose-dependent manner in FST, EPM, and TST, which were significantly different from the control group and also can significantly attenuate the motor activity and anxiety in OFT.Forced exercise, bupropion, or their combination can attenuate nicotine cessation-induced anxiety, depression, and motor activity in the mentioned behavioral assay. We conclude that forced exercise can protect the brain against nicotine withdrawal-induced anxiety, depression, and cognitive alteration.

Doxorubicin (DOX) is one of the most potent and widely used chemotherapeutic agents to treat several malignancies. However, the clinical use of DOX is seriously restricted due to its acute and chronic cardiotoxic side effects This study investigated the protective effect of (Ajwa) date aqueous extract (AJDAE) against doxorubicin-induced cardiotoxicity in rats. Sixty Wister albino male rats (150-200 gms.) were comprised in our study and divided into six equal groups: group I (untreated control), group II, group III, rats were orally received AJDAE (0.75 & 1.5 gm/ kg.bw) respectively, for 4 weeks, rats of groups IV, V and VI were intraperitoneally injected with one dose of doxorubicin (5 mg/kg.bw) at the end of the 4th week of the study to induce cardiotoxicity, rats of groups V & VI were orally received AJDAE (0.75 & 1.5 gm/ kg.bw) respectively. Cardiac enzymes, lipid profile, SOD, GR, GST, GPx, CAT and MDA in rats’ hearts homogenate, urinary 8OHdG as well as DNA integrity and histopathological changes were investigated in all studied rats.Oral administration of AJDAE (0.75 & 1.5 gm/ kg.bw) attenuated the cardiotoxicity of DOX, improved the cardiac enzymes, lipid profile, reduced the urinary 8OHdG and prohibited the depletion of endogenous antioxidants and suppressed lipid peroxidation (MDA). Moreover, AJDAE enhanced DNA integrity. Histological findings showed that AJDAE (0.75 & 1.5 gm/ kg.bw) administration reduced cardiomyocytes alterations, congestion, edema and the intense cellular stress exerted on myocardial fibers as well as restored the cardiomyocytes architecture. Our data showed that AJDAE obviously resulted in protective effects against DOX-induced cardiotoxicity in rat’s heart. It can be concluded that Ajwa date offers a considerable protection against DOX-induced cardiotoxicity.

Melatonin (ML) is a potent antioxidant that reduces oxidative stress. This study was designed to examine the protective effect of melatonin on potassium dichromate- (PDC-) induced male reproductive toxicity. Forty rats were divided into five groups: the control group, rats administered PDC orally (10 mg/kg body weight) for eight weeks, rats administered ML intraperitoneally at doses of either 2.5 or 5 mg/kg followed by the administration of PDC, and rats administered 5 mg/kg ML only. The treatment of rats with PDC led to a decrease in the levels of plasma sex hormones, glutathione, superoxide dismutase, catalase, carnitine, sperm count, and motility. Testicular malondialdehyde levels, nitric oxide concentrations, and abnormalities increased significantly in the PDC group. Melatonin administration to the PDC-treated rats reduced the increase of malondialdehyde and restored the activity of antioxidant enzymes (superoxide dismutase and catalase), glutathione, and sex hormone levels. Moreover, ML attenuated PDC-induced increase in levels of tumor necrosis factor-alpha or interleukin-6. ML alleviated histopathological changes and an increase of p53-positive immune reaction due to PDC. Furthermore, ML inhibited PDC-induced decrease in the DNA content of spermatogenic cells. This study proposed that melatonin may be useful in mitigating oxidative stress-induced testicular damage due to potassium dichromate toxicity.
