A: Saturation curve of 3H-PAF binding to cultured cirrhotic hepatic stellate cells. 3H-PAF in the concentration between 0.125 and 3.2 nmol/L,in presence or the absence of 5 μmol/L unlabeled incubated at 25°C for 3 h; B: Scatchard plot analysis of binding of 3H-PAF to cirrhotic hepatic stellate cells. Cirrhosis: Kd: 4.66 nmol/L, Bax: 24.65 ± 1.96 fmol/μg DNA, R = 0.982; Control: Kd: 3.51 nmol/L, Bax: 5.74 ± 1.55 fmol/μg DNA, R = 0.93.
