Figure 2 Terminal deoxy-nucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) staining (mean ± SE, n = 13) in cardiac myocytes isolated from rats pretreated for 7 to 10 days with nicotine (6 mg/kg/day) versus saline, and then exposed to lipopolysaccharide (LPS) (10 ng/ml) versus vehicle for 24 h. The LPS increased TUNEL staining in myocytes from saline pretreated rats (*p < 0.05, saline-LPS compared with other three groups).
