background: the contribution of neuroinflammation in alzheimer’s disease (ad) has been widely reported. the effects of female gonadal hormones in both neuroinflammation and brain cognitive functions have also been well considered. objectives: in the present study, the possible protective role for endogenous ovarian hormones against learning and memory impairment as well as brain tissues oxidati...

objective(s): in the present study, our aim was to investigate the possible protective effects of epigallocatechin gallate (egcg) on lipopolysaccharide (lps)-induced hepatotoxicity by using hep3b human hepatoma cells. specifically, the study examines the role of some proinflammatory markers and oxidative damage as possible mechanisms of lps-associated cytotoxicity. consequently, the hepatocellu...

Alcohol abuse is a common phenomenon among the countries of European continent. One first organs suffering from alcohol-induced damage liver. Activation Kupffer cells, as part mononuclear phagocyte system, plays significant role in development oxidative-nitrosative Systemic inflammatory response affects polarization macrophages throughout body and may affect alcohol hepatocytes. The aim this wo...

BACKGROUND Nonalcoholic steatohepatitis (NASH) is a progressive form of nonalcoholic fatty liver disease, for which there is currently no safe and effective drug for therapy. In this study, we explored the effects of taurine, tea polyphenols (TPs), or a combination thereof, on NASH rats. METHODS Rats were divided into a normal group, a high-fat diet induced model group and a treatment group (...

The effects of trimetazidine, a novel anti-ischemic agent, on the development of oxidative stress induced in mice with lipopolysaccharide endotoxin were investigated. The drug was administered orally once daily at doses of 1.8, 3.6 or 7.2 mg/kg for two days prior to intraperitoneal (i.p.) injection of lipopolysaccharide E (200 μg/kg) and at time of endotoxin administration. Mice were euthanized...

This study investigated the effect of the serotonin selective reuptake inhibitors (SSRIs) fluoxetine, sertraline, fluvoxamine and the tricyclic antidepressant (TCA) impiramine on oxidative stress in brain and liver induced by lipopolysaccharide administration in mice. Each drug was administered subcutaneously at doses of 10 or 20 mg/kg, for two days prior to intraperitoneal (i.p.) administratio...

BACKGROUND The acylethanolamides oleoylethanolamide and palmitoylethanolamide are endogenous lipid mediators with proposed neuroprotectant properties in central nervous system (CNS) pathologies. The precise mechanisms remain partly unknown, but growing evidence suggests an antiinflammatory/antioxidant profile. METHODS We tested whether oleoylethanolamide/palmitoylethanolamide (10 mg/kg, i.p.)...

The aim of this study was to investigate the protective effects of matrine on lipopolysaccharide (LPS)-induced inflammation and oxidative stress in vivo and in vitro. The results showed that matrine improved intestinal inflammatory status and oxidative balance and enhanced chemokine receptor 7 (CCR7) expression. In LPS-challenged mice and Caco-2 cells, matrine alleviated LPS-induced inflammatio...

This study aimed to investigate the protective effects of dexmedetomidine on lipopolysaccharide (LPS)-induced lung injury in Wistar rats. 24 female Wistar rats were randomly assigned into 3 groups (n = 8): a control group, a LPS-challenged group, and a LPS plus dexmedetomidine group. Inflammation, oxidative stress, Nrf2/Keap1, and Akt signal were determined. The results showed that LPS caused i...
