چکیده انگلیسی
Described here is an investigation of the potential interaction of the nitric oxide signaling pathway with the anticonvulsant effects of progesterone. In ovariectomized Swiss mice, the threshold for seizures induced by intravenous infusion of pentylenetetrazole was determined after treatment with progesterone (25, 50, or 75Â mg/kg, given subcutaneously 6Â h before seizure testing) or vehicle. Progesterone induced significant anticonvulsive activity at moderate (50Â mg/kg) and high (75Â mg/kg) doses. This effect of progesterone was abolished by the NO precursor compound l-arginine (200Â mg/kg). Moreover, when subeffective doses of progesterone (25Â mg/kg) and the NO synthase inhibitor NÏ-nitro-l-arginine methyl ester (10Â mg/kg) were injected, a strong anticonvulsant effect was observed. These findings suggest a potential role for NO signaling as an anticonvulsant target in females.
