abstract：:Two-day-old rats were pretreated with 50 mg/kg of capsaicin. After 3--4 months, specific binding of [3H]muscimol and [3H]strychnine was measured in membrane preparations from dorsal spinal cord. A 20-30% decrease of the number of [3H]muscimol binding sites was observed after capsaicin treatment. In contrast, [3H]stryc...
