Figure 3: Haematoxylin and eosin stained histological sections of rat ventral prostatic tissue under different conditions of sleep deprivation. The prostate of control group shows the acini (Ac) with great amount of secretion in the luminal region (Lu), and the epithelium (Ep) is visualized with conspicuous Golgi’s region (star), indicative of high secretion activity. During the sleep deprivation conditions, the acini compartment is decreased, and the presence of unilocular adipose tissue is evident (*). The thin arrow indicates an apoptotic body in the epithelium. Stroma (S).
