Figure 1From: Changes of neuregulin-1(NRG-1) expression in a rat model of overactive bladder induced by partial urethral obstruction: is NRG-1 a new biomarker of overactive bladder? Hematoxylin and eosin staining of bladder tissue. The muscular layer appears more hypertrophic in image B and C than in image A. There was no typical difference in the urothelium between the groups. A, Control group; B, overactive bladder group; C, overactive bladder treated with 5-hydroxymethyl tolterodine group.Back to article page
