Serum leptin concentrations as rats approach and during puberty (n = 10 in antileptin group A and n = 11 in control group B). Data are presented as mean ± SEM. From day 23 through day 31, no difference in leptin was observed between the two groups (P > .05). Nevertheless, at days 35, 37, and 39, there was a statistically significant increase compared to day 23 in group A (P = .013, .004, .001, resp.). For the control group of all ages, this rise in serum leptin did not occur (P > .05). Arrows indicate the mean day of VO (see Figure 1 legend for details).
