Figure 3 : A photomicrograph of buccal mucosa stained with caspase.

(a) Buccal mucosa from group I showing negative caspase-3 immunoreaction in the cytoplasm of buccal epithelial cells (arrow)[Immunostaining for caspase, X400, scale bar=25 μm]. (b) Buccal mucosa from group II showing highly expressed caspase-3 immunoreaction in the cytoplasm of buccal epithelial cells (arrow) [Immunostaining for caspase, X400, Scale bar=25 μm]. (c) Buccal mucosa of group III showing moderate caspase-3 immunoreaction in the cytoplasm of buccal epithelial cells (arrow) [Immunostaining for caspase, X400,scale bar=25 μm]. (d) Buccal mucosa from group IV showing minimal expressed caspase-3 immunoreaction in the cytoplasm of buccal epithelial cells (arrow) [Immunostaining for caspase, X400, scale bar=25 μm].
