Testicular Effect of Selenium Nanoparticles on Monosodium Glutamate Induced Alteration in Male Albino Rats.

Abstract

<b>Background and Objective:</b> The flavor enhancer Monosodium Glutamate (MSG) is mostly utilized in Asian and West African cuisines, especially in West African and Asian dishes. However, due to its availability, largely without labeling, in many food products, unintentional overuse of this food additive may occur. The objective of this study was to find out how selenium nanoparticles affected the toxicity of MSG in male albino rats' testicles. <b>Materials and Methods:</b> As 35 Wistar male rats partitioned into 5 groups: G1: Control rats, G2: Received Se-NPs at 0.4 mg kg¹ b.wt., orally, G3: Injected with MSG at a daily dose of 4 g kg¹ b.wt., intraperitoneally (IP), G4: Ingested a daily oral dose of Se-NPs for 7 successive days and on the 7th day, received the first dose of MSG IP 4 g kg¹ b.wt., then received both treatments till the end of the study and G5: Administered a daily oral dose of 4 g kg¹ MSG, followed by Se-NPs at a daily dose of 0.4 mg kg¹ b.wt., the experiment continued for 28 days. Serum testosterone hormone, Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH), the levels of serum lipid peroxidation (MDA), reduced Glutathione (GSH), Glutathione Peroxidase (GSH-Px), superoxide dismutase (SOD) and Lactate Dehydrogenase (LDH) were estimated and samples from testis were separated for histological analysis. <b>Results:</b> The MSG treatment induced a significant decline in the values of serum testosterone, FSH, LH, GSH, GSH-Px and SOD. It also increased the values of serum MDA and LDH and spermatic arrest. While, the administration of Se-NPs orally before MSG treatment resulted in a decline in the values of serum MDA and LDH, an elevation in the values of serum GSH, GSH-PX and SOD, testosterone, FSH, LH and reappearance of sperm. <b>Conclusion:</b> The use of Se-NPs as a protector exhibited more improvement in values of estimated hormones and oxidative stress markers than using it as a therapy.
