Administration of CCl4 to normal rats and consequent oral feeding with ellagic acid (50 mg/kg) provided a significant protection against the biochemical alterations in serum and liver produced by CCl4. In vitro experiments showed that liver microsomes from animals treated with ellagic acid and CCl4, decreased lipid peroxidation compared to microsome prepared from rats exposed to CCl4 alone.

Hyperacute rejection of a transplanted liver is rare even when the recipient has circulating donor-specific alloantibodies (DSA). There is also evidence that a transplanted liver may provide immunological protection for other organs transplanted from the same donor. We monitored the kinetics of circulating DSA in a highly sensitized recipient of a combined split liver and kidney transplant and ...

conclusions the current study findings indicated that echinacea purpurea extract played an important role in the protection against den toxicity in rats. results den induced hepatotoxicity and nephrotoxicity in all the treated animals by elevated serum alt, ast, alp and bun, creatinin and total and direct bilirubin levels. ast, bun and total and direct bilirubin significantly decreased in den +...

We previously demonstrated that protection induced by radiation-attenuated (gamma) Plasmodium berghei sporozoites is linked to MHC class I-restricted CD8(+) T cells specific for exoerythrocytic-stage Ags, and that activated intrahepatic memory CD8(+) T cells are associated with protracted protection. In this study, we further investigated intrahepatic memory CD8(+) T cells to elucidate mechanis...

objective(s): the objective of this study was to investigate the hepatoprotective effect of licochalcone b (lcb) in a mice model of carbon tetrachloride (ccl4)-induced liver toxicity. materials and methods: hepatotoxicity was induced in mice by a single subcutaneous injection (sc) of ccl4. the lcb was administered orally once a day for seven days (po) as pretreatment at three doses of 1, 5, and...

Our previous studies have described the protective effects of hepatoprotective agents against liver injury elicited by chloroform even when given 24 h after the toxicant, at a time when the liver injury is taking place and rapidly developing. However, the mechanisms involved in this protection remain unknown. The cytoprotective mechanism of these hepatoprotectants such as DMSO, may be due to a ...

Excess iron deposition in the liver catalyses the production of Reactive Oxygen Species (ROS) which in turn initiate oxidative damage of protein and nucleic acids leading to several human diseases. The fruits of Terminalia Belerica Roxb. (TB) has been most commonly used not only in stimulating gastrointestinal health, but also in treatment of various hepatic disorders. The present study was aim...

The effect of COX (cyclo-oxygenase)-2-dependent PGs (prostaglandins) in acute liver injury has been investigated in transgenic mice that express human COX-2 in hepatocytes. We have used three well-established models of liver injury: in LPS (lipopolysaccharide) injury in D-GalN (D-galactosamine)-preconditioned mice; in the hepatitis induced by ConA (concanavalin A); and in the proliferation of h...

Tregs are important mediators of immune tolerance to self antigens, and it has been suggested that Treg inactivation may cause autoimmune disease. Therefore, immunotherapy approaches that aim to restore or expand autoantigen-specific Treg activity might be beneficial for the treatment of autoimmune disease. Here we report that Treg-mediated suppression of autoimmune disease can be achieved in v...
