Effect of DHK on mRNA expression of ICAM-1 in the retinas. Seven days after injection of STZ, rats were orally administered for 16 weeks. At the end of the experiment, rats were sacrificed and the left retinas were then collected. Retinal total RNA was extracted from the retina using TRIzol reagent. Retinal mRNA expression of ICAM-1 was evaluated using real-time PCR method. Results were expressed as percentage relative to the normal group. Values were expressed as mean ± SEM, n = 8–10, and ^∗∗P < 0.01.
