Figure 5

Immunohistochemistry for AQP2 expression in the groups: sham ((a) and (e)), CHF ((b) and (f)), QL ((c) and (g)), and valsartan ((d) and (h)) at different magnifications. AQP2 expression was detected in principal cells in the collecting ducts, and labeling was much stronger in rats with CHF than in sham rats; labeling was much weaker in QL and Valsartan rats.
