Extracts of Melittis melissophyllum leaves in ether, chloroform, ethyl acetate, n-butanol and water were evaporated to dryness and dissolved in 50% ethanol to make 10% (w/v) solutions. The potential protective action of the extracts was assessed by the corresponding in vitro and in vivo tests. In the in vitro experiments extracts were tested as potential scavengers of free radicals (DPPH, O₂·⁻,...

Induction of heat shock proteins (hsps) is considered as an important protective, ecophysiologically adaptive, and genetically conserved response to environmental stress in all organisms. The effects of exposure to sublethal doses of CdCl2 (0.05, 0.1 and 0.2 LC50) during 14 days on mRNA-hsp70 expression in liver and gillwere investigated in juveniles of Persian sturgeon (Acipenser persicus). Fi...

Sulfasalzine is a widely administered drug against inflammatory-based disorders in human. However several cases of liver injury are associated with its administration. There is no stabilized safe protective agent against sulfasalazine-induced liver injury. Current investigation was designed to evaluate if N-acetylcysteine (NAC) and dithioteritol (DTT) as thiol reducing agents and/or vitamins C ...

Curcumin, an active ingredient of curcuma plant has been thought to be beneficial in the treatment of liver diseases. In the previous studies, we have shown the protective effects of curcumin against lipid peroxidation and swelling of the rat liver mitochondrial preparation induced by tert-butylhydroperoxide (t-BuOOH). In the present study, the administration of t-BuOOH of 90 M caused the mito...

background: chemical toxins are among the leading causes of liver disorders, inflammation and necrosis in hepatocytes. the aim of this study was to evaluate of protective effect of hydroalcoholic extract from rhizome of zingiber officinale l. (hez) on carbon tetrachloride-induced hepatic injury in male rat. material and methods: in this experimental studymale wistar rats (n=35, body weight 230-...

To explore hepatoprotective role and underlying mechanisms of Trillium tschonoskii Maxim (TTM), 36 rats were randomly divided into control, CCl4-induced liver injury model, and biphenyl dimethyl dicarboxylate (DDB) and low-, moderate-, and high-dose TTM treatment groups. After CCl4-induced model establishment, the rats from DDB and TTM groups were administrated with DDB at 0.2 g/kg per day and ...

The majority of chronic liver diseases are accompanied by oxidative stress, which induces apoptosis in hepatocytes and liver injury. Recent studies suggest that oxidative stress and insulin resistance are important in the pathogenesis of nonalcoholic fatty liver disease (NAFLD) and the pathophysiology of diabetes complications. Metformin has been shown to be hepatoprotective in the insulin-resi...

Aspirin has been used for a long time as an analgesic and anti-pyretic drug. Limitations of its use, however, remain for the gastro-intestinal side effects and erosions. Although the role of aspirin on gastro-intestinal injury has been extensively studied, the molecular mechanisms underlying aspirin-induced liver and spleen pathophysiology are poorly defined. The present study has been conducte...

Background: Several herbal remedies are used in traditional medicine for treatment of liver disorders, but their efficacy, safety, and dosage have not been investigated so far. Objective: The present study was aimed to evaluate the liver protective effects of medicinal herbs extracts such as Cynara scolymus leave (artichok), Cichorium intybus roots (chichory), Taraxacum officinale root (dande...
