a In mammary gland (bar = 100 μm), most of the ducts (arrow) were lined with a single layer of epithelial cells in control group and is surrounded by abundant fibrous collagenous tissue (*). H&E, × 200. b In 50 mg BPA-treated group (bar = 100 μm), a decrease in the number of ducts (arrow) that were lined with a single layer of epithelial cells and very abundant fibrous collagenous connective tissue (*). H&E, × 200. c In 300 mg BPA-treated group (bar = 100 μm), the number of ducts (arrow) that were lined with a single layer of epithelial cells are decreasing and fibrous collagenous connective tissue are very abundant (*). H&E, × 200. d In 600 mg BPA-treated group (bar = 100 μm), there were less number of ducts (arrow) that were lined with a single layer of epithelial cells and very abundant fibrous collagenous connective tissue (*). H&E, × 200. e In 800 mg BPA-treated group (bar = 100 μm), there were rare number of ducts (arrow) that were lined with a single layer of epithelial cells and very abundant fibrous collagenous connective tissue (*). H&E, × 200. f In mammary gland (bar = 50 μm), a faint positive reaction in the epithelial linings of the ducts (arrow) and fibrous connective tissue (*) in control group was observed, × 400. g In mammary gland of 50 mg BPA-treated (bar = 50 μm), dark positive brown reaction localized to all the borders of epithelial cell lining of ducts (arrow) and fibrous collagenous connective tissue (*), × 400. h In mammary gland of 50 mg BPA-treated (bar = 50 μm), dark positive brown reaction localized to all the borders of epithelial cell lining of ducts (arrow) and fibrous collagenous connective tissue (*), × 400. i In mammary gland of 600 mg BPA-treated (bar = 50 μm), very dark positive brown reaction localized to all the borders of epithelial cell lining of ducts (arrow) and fibrous collagenous connective tissue (*), × 400. j In mammary gland of 800 mg BPA-treated (bar = 50 μm), intense dark positive brown reaction localized to all the borders of epithelial cell lining of ducts (arrow) and fibrous collagenous connective tissue (*), × 400
