The influence of acetaminophen (APAP) treatment (400 mg/kg) on Kupffer cell function was studied in the isolated perfused liver by colloidal carbon infusion, concomitantly with parameters related to oxidative stress ...

Peripheral blood macrophages of school children from downtown Santiago, Chile-a highly polluted city-exhibited a lower phagocytic index with higher percentage of killing than those of the rural village of Marla Pinto. These ...

Boldine, in low micromolar concentrations, was able to prevent brain homogenate autooxidation, the 2,2'-azobis(2-amidinopropane)(AAP)-induced lipid peroxidation of red cell plasma membranes, and the AAP-induced inactivation ...

Chemiluminescent and respiratory responses were studied in the liver of rats treated with 0.1 mg of triiodothyronine (T)/kg for I to 7 days. Hyperthyroidism resulted in significant increments in the spontaneous chemiluminescence ...

Liver preconditioning (PC) refers to the development of an enhanced tolerance to injuring stimuli. For example, the protection from ischemia–reperfusion (IR) in the liver that is obtained by previous maneuvers triggering ...

Oxidative stress is an imbalance between pro-oxidants and antioxidants in favor of the pro-oxidants, leading to different responses depending on the level of pro-oxidants achieved and the duration of exposure. In this ...

The administration of single i.p. doses of lindane (20, 40, 60 and 80 mg/kg) to rats produced a progressive increase in the liver microsomal content of cytochrome P-450 and in the rate of superoxide anion generation, as ...

The role of Kupffer cells in the hepatocellular injury and oxidative stress induced by lindane (20 mg/kg; 24h) in hyperthyroid rats (daily doses of 0.1 mg L-3,3′,5-triio-dothyronine (T3)/kg for three consecutive days) was ...

Hormonal replacement therapy to brain-dead potential organ donors remains controversial. A retrospective study was carried out of hormonal therapy on procurement of organs in 63 593 donors in whom information on thyroid ...
