Effects of Qili Qiangxin Capsule on AQP2, V2R, and AT1R in Rats with Chronic Heart Failure

Figure 7

Immunohistochemistry for AQP2 phosphorylated at ser256 in sham ((a) and (e)) and CHF ((b) and (f)), QL ((c) and (g)), and Valsartan ((d) and (h)) at different magnifications. pS256-AQP2 immunoreactivity was detected apically in principal cells in the collecting ducts, and labeling was much stronger in CHF rats than in sham rats, while labeling was much weaker in QL and valsartan rats than in CHF rats.
