Fig. 8. Immunoblot analysis of Giαin ventricular myocardium from control, 3-h septic, and 6-h septic rabbits. (A ) Representative Western blot indicating no change in expression of 40-kDa band in sepsis. (B ) Summary comparing the immunostained band for Giαin the three groups of ventricular myocardium. Densitometric results are expressed as percentage of the band obtained with control in each experiment. Mean of data from four experiments are presented, with SD shown by vertical lines.
