Figure 4.

Effects of control-LDL (A; 0.1 mg or 0.2 mg protein ml⁻¹) or diabetic-LDL (B; 0.1 mg protein ml⁻¹) on concentration-response curve for acetylcholine-induced relaxation of aortic strips from control rats. Aortic strips were incubated with an LDL preparation for 6 h. The LDL were taken from age-matched controls or untreated diabetic rats. Each data represents mean±s.e.mean of 4–8 experiments; the s.e. is included only when it exceeds the dimension of the symbol used. ^***P<0.001, control vs diabetic LDL.
