Western blot of PAFR (A) and PAF-AH (B) proteins compared with internal standard GAPDH. Protein expression is represented as a percentage of internal standard protein GAPDH expression in bilobalide-treated groups, model and control group. Results are means±S.E.M., n=3. The black lines in the gel photographs of GAPDH indicate the places where the images have been cut and rearranged to represent the same order as the PAFR and PAF-AH bands.
