Abstract The present study aims to investigate the protective effects of zinc oxide nanoparticles (ZnO NPs) on doxorubicin-induced testicular injury. Forty mature male rats were randomly allocated into four equal groups: G1 (control), G2 (3 mg per kg BW of zinc oxide nanoparticles was administered), G3 (6 mg per kg BW of doxorubicin was intraperitoneally injected), and G4 (doxorubicin + ZnO NPs). Some fertility parameters, antioxidant status, genotoxicity assay, and a histopathological examination were used for this investigation. The doxorubicin-treated group showed a significant decrease in the index weight of reproductive organs, epididymal sperm count, motility%, and live sperm% and a significant increase in sperm abnormalities. Moreover, GSH and CAT activities were significantly decreased, and MDA content was significantly increased in the doxorubicin-treated group. Interestingly, co-administration of ZnO NPs significantly reduced the doxorubicin-induced changes in the investigated parameters. In addition, ZnO NPs alone did not show any undesirable effects on the sperm parameters, testis or DNA. However, its administration improves the reproductive parameters and significantly increases the testosterone level. We concluded that the administration of ZnO NPs at 3 mg per kg BW ameliorated the testicular toxicity and genotoxicity caused by doxorubicin through its antioxidant and androgenic activity.

Background: Oxandrolone is a synthetic testosterone analogue that is widely used among bodybuilders and athletes. However, oxandrolone causes male infertility. Recently, it was found that metformin reduces the risk of infertility associated with diabetes mellitus. Aim: This study aimed to investigate the protective effects of metformin against oxandrolone-induced infertility in male rats. Methods: Rats continuously received one of four treatments (n=7) over 14 days: control DMSO administration, oxandrolone administration, metformin administration, or co-administration of oxandrolone and metformin. Doses were equivalent to those used for human treatment. Subsequently, testicular and blood samples were collected for morphological, biochemical, and histological examination. In addition, gene expression of the testosterone synthesizing enzyme CYP11A1 was analyzed in the testes using RT-PCR. Results: Oxandrolone administration induced male infertility by significantly reducing relative weights of testes by 48%, sperm count by 82%, and serum testosterone levels by 96% (ANOVA, P value < 0.05). In addition, histological examination determined that oxandrolone caused spermatogenic arrest which was associated with 2-fold downregulation of testicular CYP11A1 gene expression. However, co-administration of metformin with oxandrolone significantly ameliorated toxicological alterations induced by oxandrolone exposure (ANOVA, P value < 0.05). Conclusion: Metformin administration protected against oxandrolone-induced infertility in male rats. Further clinical studies are needed to confirm the protective effect of metformin against oxandrolone-induced infertility among athletes.

The incorporation of cisplatin (CP) as a cytotoxic antineoplastic agent in most chemotherapeutic protocols is a challenge due to its toxic effect on testicular tissues. Natural compounds present a promising trend in research, so a new nutraceutical formulation (NCF) was designed to diminish CP spermatotoxicity. A combination of three nutraceutical materials, 250 mg Spirulina platensis powder (SP), 25 mg Tribulus terrestris L. extract (TT), and 100 mg fish oil (FO) were formulated in self-nanoemulsifying self-nanosuspension (SNESNS). SP was loaded into the optimized self-nanoemulsifying system (30% FO, 50% span 80/cremophor EL and 20% isopropanol) and mixed with TT aqueous solution to form SNESNS. For the SP, phytochemical profiling revealed the presence of valuable amounts of fatty acids (FAs), amino acids, flavonoids, polyphenols, vitamins, and minerals. Transmission electron microscopy (TEM) and particle size analysis confirmed the formation of nanoemulsion-based nanosuspension upon dilution. Method validation of the phytochemical constituents in NCF has been developed. Furthermore, NCF was biologically evaluated on male Wistar rats and revealed the improvement of spermatozoa, histopathological features, and biochemical markers over the CP and each ingredient group. Our findings suggest the potential of NCF with SNESNS as a delivery system against CP-induced testicular toxicity in male rats.

Abstract Objectives This study aimed to access the protective effects of d-ribose-l-cysteine (DRLC) on cyclophosphamide (CPA) induced gonadal toxicity in male rats. Methods Forty-eight male Sprague-Dawley rats were divided into six groups of eight rats each. Group I the control, received distilled water (10 ml/kg), Group II received a single dose of CPA 100 mg/kg body weight intraperitoneally (i.p), Groups III and IV received a single dose of CPA at 100 mg/kg (i.p) and then were treated with DRLC at 200 mg/kg bodyweight (b.w) and 400 mg/kg b.w for 10 days, respectively. Rats in Groups V and VI received DRLC at 200 and 400 mg/kg b.w for 10 days, respectively. DRLC was administered orally. Results Results showed that CPA increased percentage of abnormal sperm cells and reduced body weight, sperm count, sperm motility, follicle-stimulating hormone (FSH), luteinizing hormone (LH) and testosterone levels (p<0.05). CPA also induced oxidative stress as indicated by the increased malondialdehyde (MDA) content and reduced activities of the oxidative enzymes measured (p<0.05). Liver enzymes were elevated while the blood cells production was decreased in the rats administered CPA. DRLC supplementation enhanced the antioxidant defence system as indicated in the reduced MDA levels and increased activities of the antioxidant enzymes when compared with CPA (p<0.05). Bodyweight, sperm count, sperm motility, FSH, and testosterone levels were increased in the CPA + DRLC II group compared with CPA (p<0.05). Conclusions The results of this present study showed that DRLC has a potential protective effect on CPA-induced gonadotoxicity.

Abstract Background Tramadol is a widely used synthetic opioid. Substantial research has previously focused on the neurological effects of this drug, while the efficacy of various treatments to reduce the associated side effects has not been well studied. This study aimed to evaluate the protective effects of naloxone, diazepam, and quercetin on tramadol overdose-induced seizure and sedation level in male rats. Methods The project was performed with 72 male Wistar rats with an average weight of 200–250 g. The rats were randomly assigned to eight groups. Tramadol was administered intraperitoneally at an initial dose of 25 mg/kg/day. On the 14th day, tramadol was injected at 75 mg/kg, either alone or together with naloxone, diazepam, and quercetin (acute and chronic) individually or in combination. The rats were monitored for 6 h on the last day, and the number, the duration, and the severity of seizures (using the criteria of Racine) were measured over a 6-h observation period. The sedation level was also assessed based on a 4-point criterion, ranging from 0 to 3. Data were analyzed in SPSS software using Kruskal–Wallis, Chi-square, regression analysis, and generalized estimating equation (GEE) tests. The significance level was set at P < 0.05. Results The naloxone-diazepam combination reduced the number, severity, and cumulative duration of seizures compared to tramadol use alone and reduced the number of higher-intensity seizures (level 3, 4) to a greater extent than other treatments. Naloxone alone reduced the number and duration of seizures but increased the number of mild seizures (level 2). Diazepam decreased the severity and duration of seizures. However, it increased the number of mild seizures (level 2). In comparison with the tramadol alone group, the acute quercetin group exhibited higher numbers of mild (level 2) and moderate (level 3) seizures. Chronic quercetin administration significantly increased the number of mild seizures. In the GEE model, all groups had higher sedation levels than the saline only group (P < 0.001). None of the protocols had a significant effect on sedation levels compared to the tramadol group. Conclusion The combined administration of naloxone and diazepam in acute-on-chronic tramadol poisoning can effectively reduce most seizure variables compared to tramadol use alone. However, none of the treatments improved sedation levels.

Ischaemia Reperfusion

We investigated whether the treatment with 17β-oestradiol has renal protective effects in male rats with ischaemic acute renal failure (ARF). We also examined if the effect of 17β-oestradiol is accompanied by suppression of enhanced endothelin-1 production in postischaemic kidneys. Ischaemic ARF was induced by clamping the left renal artery and vein for 45min followed by reperfusion, 2 weeks after contralateral nephrectomy. Renal function parameters such as blood urea nitrogen, plasma creatinine and creatinine clearance were measured to test the effectiveness of the steroid hormone. Renal function in ARF rats markedly decreased 24h after reperfusion. The ischaemia/reperfusion-induced renal dysfunction was dose-dependently improved by pretreatment with 17β-oestradiol (20 or 100µg/kg, intravenously). Histopathological examination of the kidney of untreated ARF rats revealed severe lesions, such as tubular necrosis, proteinaceous casts in tubuli and medullary congestion, all of which were markedly improved by the higher dose of 17β-oestradiol. In addition, endothelin-1 content in the kidney after the ischaemia/reperfusion increased significantly by approx. 2-fold over sham-operated rats, and this elevation was dose-dependently suppressed by the 17β-oestradiol treatment. These results suggest that oestrogen exhibits protective effects against renal dysfunction and tissue injury induced by ischaemia/reperfusion, possibly through the suppression of endothelin-1 overproduction in postischaemic kidneys.
