Stained sections of the intestine (F8, B6, E7, and A5) and liver (H8, C5, G7, and D6) of the respective treatment groups (CUR200, CUR400, CUR600, and CUR800) immunostained against caspase-3 showing a moderate number of caspase-positive cells with brownish cytoplasmic reactivity in intestinal cells of different experimental groups (25%, 32%, 35%, and 45% of the cells in CUR200, CUR400, CUR600, and CUR800 groups, respectively). Meanwhile, liver sections (C5, D6, G7, and H8) immunostained with anti-caspase-3 monoclonal antibody showed mild to moderate brownish stainabilities in a variable number of hepatic and hepatic portal pancreatic cells (1.5%, 17%, 18%, and 23% of the cells in CUR200, CUR400, CUR600, and CUR800 groups, respectively). Scale bars = 10 µm.
