Figure 2.

Hematoxylin-eosin stain (a) and Sirius Red stain of collagen deposition (b) of prostatic tissues of the normal controls (upper panel), and the BPH groups (lower panel) (×200); and the quantification of collagen deposition (c). (Upper panels: normal, Gingko control, Ex control, and Gingko + Ex control; lower panels: BPH control, BPH + Gingko, BPH + Ex, and BPH + Gingko + Ex.) Data were collected and statistically treated with ANOVA and Duncan's multiple range tests (n = 3). Different letters indicate significant difference between groups (P < 0.05). BPH: benign prostate hyperplasia. Gingko: the Gingko biloba leaf extract. Ex: exercise.
