Groups of female rats (n = 18) were fed control rice, transgenic PHA-E rice or transgenic PHA-E rice spiked with 0.1% purified PHA-E lectin. Serum was obtainedat sacrifice and analyzed by ELISA. Data is represented as mean ± S.D. MLN: mesenteric lymph nodes, BW: body weight. a Data is previously presented in the paper by Poulsen et al. (2007b). * Statistically significant different from control group at p ≤ 0.05.† Statistically significant different from control group at p ≤ 0.01.
