Fig. 4From: The possible protective effect of the nuclear factor kappa B inhibitor pyrrolidine dithiocarbamate on tramadol-induced testicular damage in ratsa A photomicrograph of a rat testis section from the tramadol-treated group showing many distorted seminiferous tubules (T) with vacuolated germinal epithelium (arrow). The interstitial spaces are wide and contain few cells (I) (H&E × 100). b A photomicrograph of a rat testis section from the tramadol-treated group showing many distorted seminiferous tubules (T) with exfoliated germ cells (*). The interstitial spaces are wide (I) (H&E × 200). c A photomicrograph of a rat testis section from the tramadol-treated group showing distorted seminiferous tubules (T) with multiple vacuolations (arrow) (H&E × 400)Back to article page
