Effects of desipramine on the antioxidant status in rat tissues at carrageenan-induced paw inflammation.

The pathogenesis of many diseases and different pathological conditions, including inflammation, is associated with excess production of reactive oxygen species (ROS). The present study aimed to investigate the effects of the antidepressant desipramine (DES) on carrageenan (CG)-induced inflammation, as well as on the endogenous levels of cell enzyme and non-enzyme antioxidants in rat liver and spleen, 4 and 24 h after CG injection. The intra-plantar CG injection into the right hind paw resulted in a time-dependent increase in the paw volume; the maximum of CG-induced edema peak was in 2-4 h.

Effects of structural analogues of nociceptin(1-13)NH₂ on brain antioxidant status in kainic acid-treated rats.

The in vivo effects of nociceptin (N/OFQ(1-13)NH(2) ) and its structural analogues ([Dab(9) ]N/OFQ(1-13)NH(2) , [Dap(9) ]N/OFQ(1-13)NH(2) and [Cav(9) ]N/OFQ(1-13)NH(2) ) on the levels of lipid peroxidation and cell antioxidants (enzyme and non-enzyme) in brain of control and kainic acid (KA)-treated rats were studied. In control animals, [Dab(9) ]N/OFQ(1-13)NH(2) and [Dap(9) ]N/OFQ(1-13)NH(2) , unlike N/OFQ(1-13)NH(2) and [Cav(9) ]N/OFQ(1-13)NH(2) , slightly increased the brain lipid peroxidation; the rest of the parameters were unchanged by all neuropeptides tested. KA (0.

In vivo effects of pentoxifylline on enzyme and non-enzyme antioxidant levels in rat liver after carrageenan-induced paw inflammation.

The present study aimed to investigate the effects of pentoxifylline (PTX) on the carrageenan (CG)-induced paw oedema and on the endogenous levels of cell enzyme and non-enzyme antioxidants in rat liver, 4 and 24 h after CG injection. PTX (50 mg kg(-1) , i.p.

Antioxidant activity of fluoxetine: studies in mice melanoma model.

In vivo effects of the antidepressant fluoxetine on spleen antioxidant status of C57BL/6 mice were studied using a melanoma experimental model. After a 14-day treatment with fluoxetine (10 mg kg(-1) day(-1), i.p.

Study of the cytotoxicity and antioxidant capacity of N/OFQ(1-13)NH2 and its structural analogues.

The effect of side-chain shortening of N/OFQ(1-13)NH(2) at position 9 ([Orn(9)]N/OFQ(1-13)NH(2), [Dab(9)]N/OFQ(1-13)NH(2), [Dap(9)]N/OFQ(1-13)NH(2)) was studied regarding potential toxicity and antioxidant capacity. Staurosporine- and H2O2-induced damage of SH-SY5Y neuroblastoma cells was not changed in the presence of N/OFQ(1-13)NH(2) and [Orn(9)]N/OFQ(1-13)NH(2), but was strongly enhanced in the presence of [Dab(9)]N/OFQ(1-13)NH(2) and [Dap(9)]N/OFQ(1-13)NH(2). Moreover, treatment of cells with the latter two analogues alone led to cell injury.
