Histopathological profiles (H&E, × 400) of representative mammary tumor tissues from various experimental rat groups (n = 6). (A) The normal breast tissue of the control group: mammary acini (red narrows), conduit excretory (green narrows), breast stroma (blue narrow), adipose tissue (yellow narrow). (B) DMBA group; infiltrating carcinoma with extensive tumor necrosis (black narrow). (C) EOCc-50 mg/kg/day + DMBA; solid-cribriform carcinoma, infiltrating, with necrosis areas (black narrows). (D) EOCc-100 mg/kg/day + DMBA, solid infiltrating carcinoma with necrosis area (black narrow). (E) EOCc-200 mg/kg/day + DMBA; solid carcinoma with “papillary” areas and infiltrating adipose tissue (black narrows). (F) Carvacrol-100 mg/kg/day + DMBA; solid infiltrating carcinoma, necrosis tumor necrosis (black narrow) and infiltrating adipose tissue (yellow narrows). (G) Carvacrol-200 mg/kg/day + DMBA; solid carcinoma infiltrating adipose tissue (yellow narrows). (H) EOCc 100 + carvacrol 100 mg/kg/day + DMBA; solid carcinoma (red narrows), necrosis (black narrow), tubular areas (brown narrows).
