Effect of Morphine on Passive Avoidance Memory in Cholestatic Rats
Background and purpose: Morphine as an opioid compound has different and sometimes conflicting effects on memory and learning process. Bile duct ligation causes cholestasis, which disrupts liver function. It is known that opioid systems are involved in cholestasis. The aim of this study was to investigate the possible effect of morphine on the memory of cholestatic rats. Materials and methods:...
متن کاملThe role of hippocampal nitric oxide in passive avoidance learning
Abstract: Introduction: Nitric oxide (NO) is a retrograde messenger in hippocampal synaptic plasticity which involves in learning and memory processes. Previous studies revealed that hippocampal pyramidal cells contain NO synthase (NOS) enzyme which produce NO and could be a promising target to evaluate the role of NO in brain cognitive functions. So in this study, using NOS inhibitor (L-NAME)...

متن کاملCan ovariectomy and learning affect prefrontal cortex GABAAα1 receptor distribution in passive avoidance model in rats?
Introduction: The interaction between steroid hormones and neurotransmitters such as GABA has been proved. The regulation of muscimol binding to high-affinity GABAA receptors by estradiol and progesterone has been studied within distinct brain regions using in vitro quantitative autoradiography. There are few studies about the mechanism of the effect of steroid hormones on behaviors such as ...
