Summary
Increased microaggregate formation was found after mixing ethanol with blood from
pig and rabbit in vitro, measured with Swank’s Screen Filtration pressure method.
Final ethanol concentrations were in the range found in ethanol-intoxication in man.
No rise in SFP was noticed when plasma with 10,000 platelets/μl was used. It is therefore
doubtful that altered plasma proteins caused the rise in SFP. It is suggested that
if a direct effect of ethanol upon platelet aggregation exists in vivo, it may be
of importance in acute ethanol intoxication and in chronic alcoholism.
