Mechanism of Lycium barbarum polysaccharides on primary cultured rat hippocampal neurons.

Lycium barbarum polysaccharides (LBP) have been reported to have a wide range of beneficial effects including neuroprotection, anti-aging and anticancer. However, the anti-inflammation mechanism of LBP on primary cultured rat hippocampal neurons injured by oxygen-glucose deprivation/reperfusion (OGD/RP) is incompletely understood. We investigate the neuroprotective effects of LBP on neonatal rat primary cultured hippocampal neurons injured by OGD/RP with different approaches: MTT assay was used to detect cell viability, lactate dehydrogenase leakage was used to detect neuronal damage, formation of reactive oxygen species was determined by using fluorescent probe DCFH-DA.

Neuroprotective Effect of Oxysophocarpine by Modulation of MAPK Pathway in Rat Hippocampal Neurons Subject to Oxygen-Glucose Deprivation and Reperfusion.

Oxysophocarpine (OSC), an alkaloid isolated from Sophora flavescens Ait, has been traditionally used as a medicinal agent based on the observed pharmacological effects. In this study, the direct effect of OSC against neuronal injuries induced by oxygen and glucose deprivation (OGD) in neonatal rat primary-cultured hippocampal neurons and its mechanisms were investigated. Cultured hippocampal neurons, which were exposed to OGD for 2 h followed by a 24 h reoxygenation, were used as an in vitro model of ischemia and reperfusion.

Protective effects of aloperine on neonatal rat primary cultured hippocampal neurons injured by oxygen-glucose deprivation and reperfusion.

Aloperine (ALO), one of the alkaloids isolated from Sophora alopecuroides L., is traditionally used for various diseases including neuronal disorders. This study investigated the protective effects of ALO on neonatal rat primary-cultured hippocampal neurons injured by oxygen-glucose deprivation and reperfusion (OGD/RP).

Neuroprotective effects of oxysophocarpine on neonatal rat primary cultured hippocampal neurons injured by oxygen-glucose deprivation and reperfusion.

Context: Oxysophocarpine (OSC), a quinolizidine alkaloid extracted from leguminous plants of the genus Robinia, is traditionally used for various diseases including neuronal disorders.

Objective: This study investigated the protective effects of OSC on neonatal rat primary-cultured hippocampal neurons were injured by oxygen-glucose deprivation and reperfusion (OGD/RP).

Materials And Methods: Cultured hippocampal neurons were exposed to OGD for 2 h followed by a 24 h RP.
