عنوان انگلیسی The effects of aqueous extract of Boswellia Serrata on hippocampal region CA1 and learning deficit in kindled rats
چکیده انگلیسی مقاله Temporal lobe epilepsy (TLE) is a disorder of the central nervous system in which hippocampus is mostly involved and causes memory impairment. Kindling is a model of inducing epilepsy which is created through pentylenetetrazol (PTZ) administration. This study examines the role of the aqueous extract of Boswellia on the learning and development of brain (formation of dendritic branches and axons) of the PTZ-induced kindled rats. The study is conducted on sixty-four male rats divided into 8 groups. Kindling seizures are induced by three injections of 25 mg/kg of PTZ every 15 min. The aqueous extracts (0, 0.1, 0.5, 1 g/kg, i.p) are administrated to all animals for three consecutive days. Passive avoidance learning of animals is examined using shuttle box apparatus and step-through latency (STL) method. Rats are anesthetized and their brains are fixed by transcardial perfusion method and are analyzed by morphometric methods after applying Golgi and Cresyl violet staining methods. PTZ-induced kindling indicates a significant decrease in the number of pyramidal neurons and dendritic spines in hippocampal region cornu ammonis (CA1). The STL of the kindled rats is significantly reduced compared with control ones. Also, Boswellia extract dramatically increased the number of neuronal processes in CA1 region and improves passive-avoidance learning ability in both control and PTZ-kindled animals in 1 g/kg dose administration of Boswellia extract, especially at high doses can eliminate adverse effects of seizures on cognitive function in hippocampal area CA1 in rats.
