Photomicrographs of a uterine section (H&E stain, n = 3 from each group). Control (A–C): normal longitudinal muscle myometrium (MI), circular muscle myometrium (MII), endometrial gland (G), and inner endometrium (E). Low dose (D–F): degeneration of glandular epithelial cells and in the epithelial cells of endometrium itself (blue arrows), congested blood vessels in longitudinal muscle layer (red arrow), apoptotic cells with deeply stained pyknotic nuclei (green arrow), hyperplasia and disaggregation of epithelial cells of the luminal epithelium of endometrium layer (black arrow) and degeneration of endometrial glands with vacuolar degeneration (yellow arrow). High dose (G–I): high percentage of inflammation and dilated congested blood vessels (red arrow), high level of apoptotic cells with pyknotic nuclei (green arrow), vacuolar degeneration change (blue arrow). H Degeneration in epithelial cells of endometrium (blue arrow)
