SummaryEthanol at physiologically tolerable concentrations inhibited platelet aggregation in vitro in a relatively specific way, which may be influenced by platelet membrane lipid composition. Aggregation to collagen, calcium ionophore A23187 and thrombin (low doses) were often markedly inhibited by ethanol, adrenaline and ADP responses were little affected, and aggregation to exogenous arachidonic acid was actually potentiated by ethanol. Aggregation to collagen, thrombin and A23187 was inhibited more by ethanol in platelets enriched with saturated fatty acids than in those enriched with unsaturated fats. Platelets enriched with cholesterol showed increased sensitivity to ADP, arachidonate and adrenaline but this increase in cholesterol content did not appear to influence the inhibition by ethanol of platelet responses. The results suggest that ethanol may inhibit aggregation by an effect on membrane fluidity and/or calcium mobilization resulting in decreased activity of a membrane-bound phospholipase.

Fear occurs in various forms: existential, pathological, physical and mental. This article gives a general survey of Freud's and Lacan's conceptions. While the founder of psychoanalysis conceives of fear mainly as a corporeal fear of castration, Lacan emphasises the more extended dimension of symbolic castration which is, through the concept of scarcity, directly connected with desire and fear. The pathological side of fear becomes apparent in the defence against existential fear, in phobias, that replace the unfathomable object of fear by a manageable one.
