Fig. 7From: The possible protective effect of the nuclear factor kappa B inhibitor pyrrolidine dithiocarbamate on tramadol-induced testicular damage in ratsA photomicrograph of rat testis section from the PDTC + tramadol-treated group showing near normal histological structure. The seminiferous tubules lumen was patent (T) and some showed aggregation of sperms. Few vacuolations in the germinal layer (arrow) were noticed. Profiles of seminiferous tubules are separated by narrow interstitial spaces (I) (H&E × 200)Back to article page
