Influence of oral administration of GTE on caspase-3 protein expression in the liver of CNP-intoxicated rats. a Group I and d group IV showed negatively immune stained cells for caspase-3 protein expression. Group II (b) showing marked elevation for the positively immune stained cells. Group III (c) showing reduced number of positively stained cell. e The bar chart represents the relative number of immune positive cells for caspase-3 protein in liver tissue of different groups. Values are expressed as mean ± SE. Different superscript letters are significantly different (p < 0.05). GI (group I, control), GII (group II treated with CNPs), GIII (group III treated with CNPs plus GTE), and GIV (group IV treated with GTE)
