Body weight

Groups	Body weight (g) at MNU injection (mean ± SEM)	Body Wt. (g) at Sacrifice (mean ± SEM)
P-Un	286 ± 3.2 (n = 7)	303 ± 3.5 (n = 6)
P-IGF-I	286 ± 6.2 (n = 7)	317 ± 4.5 (n = 6)
AMV	293 ± 5.4 (n = 7)	309 ± 9.6 (n = 6)

Body weight at the time of N-methyl-N-nitrosourea (MNU) injection and just before the animals were killed at the termination of the experiment for untreated parous rats (P-Un), parous rats treated with insulin-like growth factor-I (P-IGF-I), and untreated virgin rats that were age matched with the parous animals (AMV).
