Fig 2. Effect of DPP extract (Ext) on testicular activity of: (A) 3β-hydroxysteriod dehydrogenase (3β-HSD) and (B) 17β-hydroxysteriod dehydrogenase (17β-HSD) in normal, L-T4- and PTU-treated rats.

The data are presented as mean ± SEM (n = 10 rats/gp). The symbols * and ** represent statistical significant at p<0.05 and p<0.01, respectively. ^a: significant difference from normal control values, ^b: significant difference from Ext values, ^c: significant difference from L-T4 values and ^d: significant difference from PTU values.
