As shown in photos of Figure 9, immunohistochemical detection of interleukin (IL)-6 with hepatic tissue revealed the CML alone group to exhibit the largest stained area (~26.4%), while the CML + rHDL-1 group showed the smallest IL-6-stained area of only 2.4%. This evidence concerns the gene IL6 and chronic myelogenous leukemia, BCR-ABL1 positive.
