Fig. 2. Thromboxane B2(TXB2) concentrations of platelets not stimulated (basal, n = 6 each) or stimulated (1 μM, n = 4 each) with adenosine diphosphate (ADP), epinephrine (Epi; 2 μM, n = 8 each), arachidonic acid (AA; 1 mM, n = 7 each), or prostaglandin G2(PGG2; 25 μM, n = 6 each) in the presence of propofol (40 or 100 μM) or equivalent volume of Intralipos. Data are expressed as mean ± SD. * P < 0.05 and ** P < 0.01 significantly different from that with equivalent volume of Intralipos.
