Table 2 IgA levels in blood plasma and small intestinal mucosa

Group	n	Blood plasma IgA (µg/mL)	Mucosa tissue IgA (µg/g)
Con	8	146.73 ± 18.03a	507.48 ± 59.18a
EN	10	260.37 ± 38.54b	733.51 ± 81.42b
PN	9	133.94 ± 21.47	489.38 ± 14.27
Sep	8	194.52 ± 39.31	511.89 ± 52.33

Data are expressed as mean ± SE;

^aP < 0.05 vs EN group;

^bP < 0.01 vs PN group; r = 0.998, P = 0.002, P < 0.003, there was a positive correlation in IgA level in blood plasma with that in intesti-nal mucosa.
