The pharmacological effects of nitric oxide synthase (NOS) inhibitors, NO donor, and NOS substrate on dynorphin(Dyn) A(1-17) spinal neurotoxicity were studied. Intrathecal (i.t.) pretreatment with both 7-nitroindazole 1 micromol, a selective neuronal constitutive NOS (ncNOS) inhibitor, and aminoguanidine 1 micromol, a selective inducible NOS (iNOS)(More)
It has recently been demonstrated that selective inhibition of both neuronal constitutive and inducible nitric oxide synthases (ncNOS and iNOS) is neuroprotective in a model of dynorphin (Dyn) A(1-17)-induced spinal cord injury. In the present study, various methods including the conversion of 3H-L-arginine to 3H-citrulline, immunohistochemistry and in situ(More)
Substitution urethroplasty for the treatment of male stricture disease is often accompanied by subsequent tissue fibrosis and secondary stricture formation. Patients with pre-existing morbidities are often at increased risk of urethral stricture recurrence brought upon in-part by delayed vascularization accompanied by overactive inflammatory responses(More)
The present review summarizes the effects of drugs that block N-methyl D-aspartate receptor complex (NMDA-RC) on the development of opiate tolerance and abstinence. Using behavioral pharmacological approaches, pre-clinical studies demonstrate that noncompetitive and competitive NMDA receptor antagonists and glycine binding site antagonists can inhibit(More)
Molecular mechanism of opioid effect was studied in mouse brain using alpha-CAO (7 alpha-N, N-Bis (beta-chloroethyl)amino-6, 14-endo-ethenotetrahydrooripavine), an irreversible opioid receptor agonist. There was a biphasic response in cerebral cAMP content, including an initial sharp decline and a subsequent increase 3 days later, the response being in line(More)
