Ginkgolides A and B protect against PAF-mediated synapse damage. The synaptophysin content of untreated neurons (Con) (hollow squares) or neuronal cultures pre-treated for 3 hours with 1 μM ginkgolides A or B or 25 μM myricetin or quercetin (solid squares) as shown and subsequently incubated with 25 nM PAF for 24 hours. Values shown are the mean synaptophysin content ± SD from 6 observations.
