Fig. 4

Photomicrographs of hepatic tissue of black seed group stained with H&E stain (a) and crossmon trichrome stain (b) demonstrating the protective effect of black seed grains against hepatic damage induced by heat stress. The hepatic architecture in normal with hepatocytes arranged in hepatic cods (white arrow) around the central vein (Cv), which surrounded by less collagenous fibers (C). Very small vacuolated hepatocytes were found. c, d Photomicrographs of the propolis fed group stained with H&E stain (c) and crossmon trichrome stain (d) showing the presence of the heat-stressed-mediated damage with no protective effect on the hepatic tissue. Note severe hepatocytes vacuolation (V), swollen and congested central vein (Cv), and collagenous fiber depositions (C), bar = 50 μm
