Bisphenol A (BPA) is a widespread compound associated with the manufacture of many consumer products. The BPA-induced reproductive toxicity was reported to be mainly attributed oxidative stress. However, role antioxidants usage decrease injurious effects BPA, on male functions, remains unveil. present research established evaluate selenium (Se) and its nano form (NSe) as protective agents alleviate testicular toxicity. Ninety mature albino rats were assigned into six equal groups: negative...

This study aims to investigate the effect of Premna odorata (P. odorata) (Lamiaceae) on hepatic and nephrotoxicity induced by aluminum chloride (AlCl3) in rat. Wistar male rats were equally classified into four groups: control, P. extract (500 mg/kg B.W.), AlCl3 (70 plus groups. All treatments given orally for 4 weeks. Serum transaminases some biochemical parameters, renal antioxidant/oxidant biomarker; tumor necrosis factor-α (TNF-α); matrix metalloproteinase (MMP9) transforming growth...

Salvia plants become more popular due to their health-promoting and antioxidant potential. The present study aimed investigate the safety limit of officinalis terpenoids-rich fraction in Wistar rats. Thirty adult female rats were divided equally into three groups. first one was control. second third groups received as a single oral dose 2 3 g/kg b.w., respectively. During experimental period, any abnormal clinical signs, morbidity mortality rates, well weekly body weight gain recorded. At...

Methotrexate (MTX) has been widely used for treatment of cancer and rheumatoid arthritis, but its use limited by nephrotoxicity. This study was carried out to determine whether garlic exerts a protective effect against MTX-induced nephrotoxicity.Nephrotoxicity induced in rats after single i.p. injection MTX (20 mg/kg). Garlic extract (1 mL/100 g b.w.) given orally 7 days before administration. Serum samples were collected evaluate urea, creatinine, sodium, phosphorous, potassium, calcium....

Cadmium (Cd) is a highly toxic heavy metal that adversely affects both human and animal health. Chronic cadmium exposure causes serious kidney damage. The current study investigated the protective role of cerium oxide nanoparticles (CeO2NPs) against chloride (CdCl2)-induced renal injury.One hundred twenty male albino rats were divided into 6 equal groups. Group (C): considered as control group which was given distilled water orally. (NC.1 NC.5): injected i.p. with nanoceria at dose (0.1 0.5...

Most of the currently used toxicity assays for environmental chemicals use acute or chronic systemic reproductive endpoints rather than neurobehavioral endpoints. In addition, current standard approaches to assess are time-consuming. Therefore, with increasing numbers being developed potentially harmful effects in higher vertebrates, including humans, more efficient means assessing neuro- and required. Here we discuss a Galliformes-based avian test battery which developmental is assessed by...
