Table 2. Characteristics of the Platelet-Rich Plasma used in the study with respect to concentration, activation, and method of application .

Concentration	Platelets, 103/L	WBC, 103/L	RBC, 103/L	Fibrinogen, mg/dL
	918.14 ± 149.61	0.02 ± 0.01	0.15 ± 0.07	NA
Activation	Activation status (%)*			Activation method
	NA			calcium alone
Method	State	Volume (ml)	Number	Interval (day)
gel	3x3	1	0

Data are expressed as average ± standard deviation in concentration properties. *Activation status was measured using flow cytometry with CD 61 and CD 62P in five patients. Results were expressed by the percentage of CD 62P-positive counts over CD 61-positive counts. WBC White blood cells, RBC Red blood cells, NA Not available
