The values of PE E_maxand EC₅₀on aortic rings in the different groups of rats

Group	E_max(g)	EC₅₀(nmol/l)
Control	1.86 ± 0.04	8.55 ± 0.08
LPS shock	0.95 ± 0.01^a	13.49 ± 0.06^a
Ala-Gln+LPS	1.27 ± 0.02^a,b	10.15 ± 0.04^a,b

Data are shown as mean ± standard deviation (n = 8 in each group). ^aP < 0.05 versus the control group; ^bP < 0.05 versus the LPS shock group. Ala-Gln+LPS, alanyl-glutamine dipeptide + lipopolysaccharide shock; E_max, maximum efficacy; EC₅₀, median effective dose; LPS, lipopolysaccharide.
