Objectives : We can find out the experimental reports of Yanggyuksanhwa-tang, which has the function of regulating blood pressure related with cerebral disease, and increasing local cerebral blood stream volume, also has the recoveries for the damage of vessel endothelium, and endothelium hypertrophy caused by angiospasm after subarachnoid hemorrhage, and reduces the contraction of smooth muscle, so simultaneously improves necrosis. The aim of this study is to investigate effect of Yanggyuksanhwa-tang protecting neuronal cells from being damaged by brain ischemia through using organotypic hippocampal slice cultures.Methods : We caused ischemic damage to organotypic hippocampal slice cultures by oxygen and glucose deprivation, and Yanggyuksanhwa-tang extract was added to cultures. Thereafter we measured area percentage of propidium iodide (PI)-stained neuronal cell, lactate dehydrogenase (LDH) levels in culture media and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL)-positive cells.Results : Area percentage of PI-stained neuronal cells and count of TUNEL-positive cells in CA1 and DG area of organotypic hippocampal slice culture were significantly decreased in pertinent density level of Yanggyuksanhwa-tang extract. LDH levels in culture media of organotypic hippocampal slice culture were significantly decreased in pertinent density level of Yanggyuksanhwa-tang extract.Conclusions : Within pertinent density level, Yanggyuksanhwa-tang has cell protection effect that prevents brain ischemia damaging neuronal cells and apoptosis increasing.
