<p>Testicular fragments obtained from normal rats were incubated with medium containing or not DETA-NO for 18h. Representative Western blots and semiquantitative results obtained by densitometric analysis of Western blots. A.U.: arbitrary units. Data from medium were arbitrarily set at 1. A) Cytochrome c content in the cytosolic fractionand B) Ratio of Bax/Bcl-2 content in the mitochondrial fraction (n = 10 rats) C) Caspase 9 processing and D) activity (colorimetric assay) in the cytosolic fraction (n = 10 rats). Each bar represents mean±SEM. *p<0.05 and **p<0.01 vs. medium. One sample t Test.</p
