Fig. 1 Level of carbonyl groups in kidneys of hamsters throughout the estradiol administration. (Statistically significant difference in Student's t-test between the treated and control groups has been indicated as follows: * P<0.05, ** P<0.01 and *** P<0.001.)

Fig. 2 Kidney weight of estrogenized and control animals presented as a percent of total body mass. (Statistically significant difference in Student's t-test between the groups * P<0.05, ** P<0.01, *** P<0.001.) Pathophysiology 2002 8, 269-273DOI: (10.1016/S0928-4680(02)00019-6)

Fig. 3 Testes weight in the estrogenized and control animals presented as a percent of total body mass. (Statistically significant difference in Student's t-test between the groups * P<0.05, ** P<0.01, *** P<0.001.) Pathophysiology 2002 8, 269-273DOI: (10.1016/S0928-4680(02)00019-6)

Fig. 4 Histopathologic images of kidneys of estrogenized hamsters: (A) arrow indicates an interstitial hyperplastic focus after 3 months of estrogenization (H+E, 400×); (B) arrow indicates a large proliferative focus surrounding a glomerulus after 6 months of estrogenization (H+E, 400×); (C) circle indicates neoplastic lesion (most probably of blastemal origin) after 9 months of estrogenization (H+E, 400×).
