The nitrergic system, which involves nitric oxide (NO) and NO synthase (NOS) enzymes, plays a complex role in seizure pathophysiology. Pentoxifylline (PTPh), an FDA-approved phosphodiesterase inhibitor, has anticonvulsant effects; however, its relationship with the pathway is unclear. This study focused at how the nitrergic system could be involved in PTPh’s anticonvulsant effects.</div></div><div><h3>Methods</h3><div>Seizures were induced in male mice by intravenous pentylenetetrazole (PTZ) infusion (absence-like seizures), intraperitoneal PTZ injection, and maximal electroshock (generalized tonic-clonic seizures). PTPh was administered at various doses, alone or in combination with the NO precursor L-arginine, as well as non-selective (L-NAME) and selective NOS inhibitors (nNOS inhibitor 7-NI and iNOS inhibitor aminoguanidine).

Additionally, the tinnitus group exhibited higher anxiety levels than the control group in both behavioral tests. Moreover, NLGN2 protein expression was increased in the amygdala nucleus of sodium salicylate-induced tinnitus rats compared to controls, while BDNF protein expression was reduced.
