(a) Smooth muscle surface density measured by the point-counting method in the corpus cavernosum of normotensive and hypertensive rats ( = 0.012). (b) Smooth muscle surface density measured by the color-based segmentation method, in corpus cavernosum of normotensive and hypertensive rats ( = 0.038) (columns and error bars represent the mean and standard deviation, resp.). Results shown are those of observer A.
