This study investigated the ameliorative potential of methanolic date flesh extract (MDFE) against cisplatin-induced hepatic injury. Twenty male rats (weighing 180–200 g) were allocated into four groups: control; date flesh (DF) group (oral 600 mg/kg MDFE for 21 days); Cis group (7.5 mg/kg i.p. at day 16); and date flesh/cisplatin (DF/Cis) group (oral 600 mg/kg MDFE for 21 days and 7.5 mg/kg i.p. at day 16). Hepatic biochemical parameters in sera, and inflammatory and oxidant/antioxidant hepatic biomarkers were estimated. Hepatic histological changes and the immunohistochemistry of cyclooxygenase-2 (COX-2), nuclear factor kappa B (NF-κB), and alpha smooth muscle actin (α-SMA) were assessed. Pretreatment with MDFE decreased Cis-triggered liver biochemical parameters, oxidative stress, inflammatory biomarkers, and histological damage. Moreover, MDFE treatment reduced Cis-induced hepatic NF-κB, COX-2, and α-SMA protein expression. MDFE exerted a hepatoprotective effect when used concomitantly with Cis. Its effect was mediated via its antioxidant and anti-inflammatory ingredients.

The aim of these investigations was to study vitamin E supplement effect in male albino rats after 30 days of repeated treatment. Four groups of six male rats were orally administered distilled water (control), 500, 1000 and 2000 mg/kg body weight vitamin E daily for 30 days. The impact of the treatment on percent body weight and mortality was determined and compared to the control group. Some hematological analysis, biochemical parameters and histological examination of different body organs were assessed. The rats treated with different doses of vitamin E supplement showed no deaths recorded in 30 days. The treatment with higher dose Vitamin E supplementation" caused significant alteration at the hematological, biochemical and histological level. Therefore, oral administration of vitamin E supplement in rats for 30 days was not safe for the liver and kidney and in the other hand, safe for the testes therefore that side effect on the liver and kidney should be considered when recommended vitamin E for therapeutic purpose. Care should be taken in taking high doses of vitamin E.

Acetamiprid (neonicotinoid insecticide) and azoxystrobin (fungicide) are widespread pesticides used for pest management, but they have the potential for toxicity to mammals. The goal of this study was to look for oxidative stress, metabolic alterations, and reproductive problems in male rats’ serum after 2 months of exposure to sub-lethal dosages of acetamiprid and azoxystrobin. Seven classes of male rats were formed: control, 3 groups of acetamiprid (1/10, 1/20, 1/40 LD50), and 3 groups of azoxystrobin (1/10, 1/20, 1/40 LD50) and were orally daily treated (n = 8/group). Our findings revealed that acetamiprid and azoxystrobin disrupted oxidative and metabolic processes in the examined rats throughout 30 and 60 days of testing. The levels of nitric oxide increased significantly, while catalase, a superoxide dismutase enzyme, and glutathione reductase activity were reduced. Serum levels of sex hormones, calcium, and total protein have all dropped substantially in rats. In comparison to the control group, the testis and liver structure, as well as spermatozoa parameters, had distinct histological characteristics. In conclusion, acetamiprid and azoxystrobin exhibit dose- and time-dependent effects on oxidative parameters that cause testis damage.
