Expression of MRP1 and MRP2 in peripheral blood mononuclear cells of children with intractable epilepsy (mean ± SD).

Group	Cases	MRP1	MRP2
Group of healthy children without epilepsy	50	1.093±0.023	1.045±0.018
Group of children with epilepsy controlled by anti-epileptic drugs	50	1.131±0.042a	1.086±0.027a
Group of intractable epilepsy	50	2.027±0.034b	1.902±0.021b
F-value		20.391	24.197
P-value		<0.001	<0.001

^aP<0.001 when the group of children with intractable epilepsy was compared to the group of children with epilepsy controlled by anti-epileptic drugs and the group of healthy children without epilepsy.

^bP>0.05 when the group of children with epilepsy controlled by anti-epileptic drugs was compared to the group of healthy children without epilepsy. MRP, multidrug-resistant associated protein.
