Alteration of alpha granule numbers in patients with acute cerebral infarction.

Data are expressed as mean ± SD. There are 20 patients and controls in each group at each time point. ^aP < 0.05, vs. normal (control group); ^bP < 0.05, vs. 7 and 15 days postocclusion group (Student's t-test followed one-way analysis of variance). At each time point, alpha granules were lower than those from control, and showed significant decrease at 1 day after infarction.
