Body weight (g)	271 ± 10.8	290.6 ± 5.28	306 ± 18.0	286.1 ± 7.73	303 ± 12.9	288.6 ± 18.1	312.6 ± 8.7
Spleen weight (g)	1.015 ± 0.17	1.127 ± 0.09	0.995 ± 0.04	1.000 ± 0.04	0.821 ± 0.03	1.11 ± 0.13	1.097 ± 0.08
Relative spleen weight (%)	0.367 ± 0.03	0.388 ± 0.03	0.328 ± 0.02	0.349 ± 0.01	0.272 ± 0.01	0.384 ± 0.03	0.352 ± 0.03
Brain weight (g)	1.709 ± 0.14	1.846 ± 0.03	1.875 ± 0.038	1.848 ± 0.049	1.757 ± 0.058	1.782 ± 0.084	1.768 ± 0.072

Abbreviations: Wt, weight; g, gram. All the values are expressed as mean ± SEM (n = 4). There was no statistical significance among the groups. Relative organ weight = weight of the organ/body weight*100.
