Indices of acute in vivo platelet activation in response to cigarette smoking were
sought in 10 healthy subjects. Judging by platelet aggregate ratio, platelet factor
4 and beta-thromboglobulin measurements, platelet activation took place from 10 to
30 min after smoking in most subjects. These signs correlated well with the results
of scintigraphic studies showing signs of accumulation of 111-In-labelled platelets
in the spleen in response to smoking.
