Fig. 10.

Top: myocardial cGMP, maximal in vitro PKG activity, and PKG forms. Total LV myocardial cGMP concentration was increased in radiated rats compared with control rats (A), while in vitro maximal PKG activity (B) and the ratio of dimer to monomer PKG forms (C) did not differ between radiated and control rats. Data are shown as scatter dot plots, with lines showing mean and 95% confidence interval. *P < 0.05 vs. control. †Post hoc test for linear trend P < 0.03. Bottom: representative Western blots for PKG (dimer and monomer forms).
