Plot of the association of tissue cholesterol and GAG distribution in segments of thoracic aorta from control (A) and diabetic (B) monkeys. Percent GAG were measured as areas under the curves of stained GAG following agarose electrophoresis as shown in figure 2. Values used in the correlational analyses are the sum of GAG of guanidine extracted + non-guanidine extracted PG. Correlation coefficients and significance are shown. In A: percent DS, Y = 2.96X - 20.32. In B: percent DS, Y = 3.90X - 28.51; percent HS, Y = -1.86X + 104.59. HS, heparan sulfate; DS, dermatan sulfate; CS, chondroitin sulfate; dlt, delipidated tissue.
