“…The increase in serum TSH levels produced by lead may be linked to structural injury of thyroid follicular cells due to the accumulation of lead in the thyroid gland. This is similar to Algefare et al [54], who observed that the elevation in serum TSH level induced by lead acetate is likely a response to the decrease in serum T4 and T3 levels in rats. Thyroid hormones play essential roles in the development of the central nervous system (CNS).…”

Background: Lead is widely distributed in the environment and has been associated with a variety of negative health impacts. The present study investigated the use of Echinacea with lead acetate in decreasing or preventing the serious side effects of lead on the brains of male rats. Methods: Twenty-four rats were distributed into four groups randomly. Group1: Rats orally administered 1ml of distilled water followed by an intraperitoneal (I.P) injection of 1ml of physiological saline (control group). Group2: Rats I.P injected with lead acetate (50 mg/kg b.w/day, 3 days a week for 4 weeks). Group3: Rats orally administered Echinacea (150 mg/kg b.w./day for 4 weeks). Group4: Rats administrated with Echinacea plus lead acetate with the same doses of G2 and G3. Results: Lead exposure resulted in a significant elevation in nitric oxide (NO) production and malondialdehyde (MDA), along with a decline in reduced glutathione (GSH) and enzyme activities of superoxide dismutase (SOD) and catalase (CAT) in the rats' brain. These results were linked with significant increases in aminotransferase enzymes, lactate dehydrogenase (LDH), alkaline phosphatase (ALP) in brain tissues and serum thyroid stimulating hormone (TSH) levels. Abnormal histopathological changes and increased caspase-3 immunopositivity were also observed in comparison to control. The co-treatment with Echinacea in lead-exposed rats improved all of these changes. Conclusions: This study pointed out that Echinacea could be used as an alternative treatment to counteract the negative effects of lead acetate.

“…In the current study, the exposure to Al 2 O 3 NP s and/or PbAc decreased sperm count and sperm motility while it increased the abnormal sperm count. Comparable impaired sperm parameters were observed in rats exposed to Al 2 O 3 NP s [ 5 ] or PbAc [ 38 , 99 ]. The reduction in sperm motility was most likely caused by the influence of Al 2 O 3 NP s on mitochondrial function.…”

This study examined the effects of exposure to lead acetate (PbAc) and/or aluminum trioxide nanoparticles (Al2O3NPs) on testicular function. Additionally, the probable reproprotective effects of quercetin (QTN) against Al2O3NPs and PbAc co-exposure in male Sprague Dawely rats were assessed. Al2O3NPs (100 mg/kg b.wt.), PbAc (50 mg/kg b.wt.), and QTN (20 mg/kg b.wt.) were orally administered for 60 days. Then, spermiogram, histopathological examinations of the testis and accessory glands, and immunohistochemical detection of androgen receptors (AR) and tumor necrotic factor alpha (TNF-α) were achieved. Moreover, serum levels of male sex hormones and testicular levels of antioxidant indices were estimated. The results showed that Al2O3NPs and/or PbAc caused significant sperm abnormalities, testicular oxidative stress, and histopathological changes. Furthermore, serum testosterone, LH, and FSH levels significantly decreased, while estradiol levels significantly increased. The Al2O3NPs and/or PbAc co-exposed group had more obvious disturbances. Furthermore, QTN co-administration significantly reversed the Al2O3NPs and PbAc-induced testicular histopathological alterations, reduced antioxidant defenses, and altered AR and TNF-α immune expression in testicular tissues. Conclusively, Al2O3NPs and/or PbAc evoked testicular dysfunction by inducing oxidative injury and inflammation. However, QTN oral dosing effectively mitigated the negative effects of Al2O3NPs and PbAc by suppressing oxidative stress and inflammation and improving the antioxidant defense system.
