1. 7-Nitro indazole (7-NI, 10-50 mg kg-1), 6-nitro indazole and indazole (25-100 mg kg-1) administered i.p. in the mouse produce dose-related antinociception in the late phase of the formalin-induced hindpaw licking and acetic acid-induced abdominal constriction assays. The ED50 values (mg kg-1) were as follows: 7-NI (27.5 and 22.5), 6-nitro indazole (62.5(More)
Leptin is a 16 kDa hormone that is produced by adipose tissue and has a central effect on food intake and energy homeostasis. The ability of leptin to cross the blood-brain and blood-cerebrospinal fluid (CSF) barriers and reach or leave the CNS was studied by the bilateral in situ brain perfusion and isolated incubated choroid plexus techniques in the rat.(More)
L-NG-nitro arginine p-nitroanilide (L-NAPNA), L-NG nitro arginine methyl ester (L-NAME) and L-NG-monomethyl arginine (L-NMMA) inhibit rat cerebellar nitric oxide synthase (NOS) with IC50s of 1.4 +/- 0.1 microM, 0.81 +/- 0.16 microM and 5.1 +/- 0.07 microM respectively. L-NAPNA inhibits the late phase of formalin-induced hindpaw licking (ED50, 57.2 mg kg-1)(More)
Co-administration of the nitric oxide synthase inhibitor, 7-nitro indazole (1 mg/kg i.p.), with the cyclooxygenase inhibitor, flurbiprofen (5-75 mg/kg i.p.), resulted in significantly enhanced antinociceptive activity in mice (formalin-induced hindpaw licking assay) without affecting hindpaw inflammation. No antinociception was observed in animals(More)
1. The effect of the nitric oxide synthase (NOS) inhibitor, 7-nitro indazole (7-NI), on sympathetic and purinergic neurotransmission in the rat isolated vas deferens preparation has been studied. 2. 7-NI (50-200 microM) caused a dose- and frequency-dependent inhibition of the phasic (predominantly purinergic) contractile response of the rat vas deferens to(More)
