Changes in PLT count (A) and MPV (B) before initiation of ECC(T0), 30 minutes after initiation of ECC(T0.5), ACT and T1 in 6 (T6), 12 (T12), and 24 (T24) hours after initiation of ECC in the control (□) and LLLT group (■). Data are expressed as the mean ± SEM (n = 12/group). *p < 0.05, LLLT group compared with the control group at the sampling time. Changes in the values of the measurement points in a given group during the experiment were denoted by: ↓↓, ↓, ●, ↑. Values marked with the same symbol do not differ significantly.
