Abstract: The paf-acether antagonist is a triazolothieno-diazepine (or its analogue), a ginkgolide, a ginkgolide mixt. synthetic ginkgolide deriv. or a paf-acether analogue such as CV3988.  The lipoprotein is LDL or VLDL.The triazolothieno- diazepine is specifically WEB2086, WEB 2098 or BN50739, and the ginkgolide is BN52020, BN52021 and/or BN52022. Also claimed is a procedure for determining the efficacy of a paf-acether antagonist, which involves the following procedure. (a) purified cells are mixed with labelled paf- acether and the antagonist in the presence of lipoproteins (e.g. LDL, LA-paf or VLDL), LA-paf and/or cholesterol; (b) another sample of the same cells is mixed with labelled paf-acether, lipoproteins, LA-paf and/or cholesterol, in the absence of antagonist; (c) the cells are sepd. from the mixts. (a) and b); and (d) the quantity of labelled paf-acether bound to the cells is measured in each case.  The difference between the deg. of binding in (a) and (b) is taken as a measure of the antagonist's effectiveness.  The cells are concd. platelets or monocyte- macrophage-like cells (specifically U937 cells) taken from a culture and stimulated with lipoprotein and/or cholesterol in a delipidated medium.  The cells are purified by washing in an isotonic buffer and are suspended in a buffer contg. serum albumin.
