Figure 7

Immunohistochemical detection of indices of apoptosis (TUNEL; panel A) and proliferation (PCNA; panel B) were performed as described in methods. Representative photomicrographs (200×) are shown. Panels C and D show summary of quantitation of staining. a, p < 0.05 compared to the saline injection; b, p < 0.05 compared to animals exposed to tap water.
