Fig 8. Effect of long-term CLA supplementation on immune histochemistry of Caspase-3 rabbit testicular tissue.

Fig 8

Negative staining for caspase-3 in the control group (8a). Brown positively stained spermatogonial cells were observed in the lumen and in the lining epithelium of seminiferous tubules in CLA 0.5% (8b), and CLA 1% (8c) groups. Immuno-peroxidase and hematoxylin counterstain X 400. Area percent of Caspase-3 in different groups, long term dietary supplementation of CLA increased area percentage of Caspase-3 in a dose dependent manner (8d).
