ABSTRACT
Effects of EGb on cultured bovine aortic endothelial cells (BAEC) damaged by lysophosphatidylcholine (LPC) were investigated. When endothelial cells were incubated with LPC (2.5 micrograms.ml-1) for 24 h, the endothelial cells turned round pyknotic, exfoliated and broken, and the contents of malondialdehyde (MDA), lactate dehydrogenase (LDH) and plasminogen activator inhibitor (PAI) were markedly increased and the superoxide dismutase (SOD) activity was inhibited. Treatment with EGb at concentrations of 125 and 250 micrograms.ml-1, caused a reduction in MDA, LDH and PAI contents, while the SOD activity in the medium was increased and the morphologically damaged BAECs were alleviated. These results suggest that EGb afforded protection against BAECs damages induced by LPC and that the protective effect of EGb may be due to anti-lipid peroxidation via free-radical scavenging activity.
