Figure 2: A photomicrograph of submandibular salivary gland of the saline/distilled water group shows (A1) negative Ki-67 immuno reactivity in nuclei of cells of ducts and acini and (A2) negative cytoplasmic reaction to caspase-3 (immunohistochemistry ×400). Saline/chamomile group shows (B1) negative Ki-67 immuno reactivity in nuclei of cells of ducts and acini and (B2) negative cytoplasmic reaction to caspase-3 (immunohistochemistry ×400). 5-FU/distilled water treated group shows (C1) negative Ki-67 immuno reactivity in nuclei of cells of ducts and acini and (C2) mild cytoplasmic reaction to caspase-3 (immunohistochemistry ×400). 5-FU/chamomile extract treated group shows (D1) negative Ki-67 immuno reactivity in nuclei of cells of ducts and acini and (D2) moderate cytoplasmic reaction to caspase-3 (immunohistochemistry ×400).
