using a morphological scoring system of 0 ( no cardiac damage ) to 3 ( involvement of almost the complete ventricular cross-section sampled ) , a cm score of 1.8 +/- 0.1 was found in rats harboring pheochromocytoma , a significant increase over that in age- and sex-matched controls ( 0.4 +/- 0.1 , p less than .001 ) .
