Experimental Group Day 1 (8 am) treatment Day 2 (8 am) treatment Day 3 (8 am) Uterine weight (g)
OvxC (n = 5) vehicle vehicle sacrifice 0.092a ± 0.008
24E (n = 6) E2 sacrifice   0.162bcd* ± 0.019
24P (n = 6) P sacrifice   0.122abc ± 0.013
48E (n = 6) E2 E2 sacrifice 0.215b* ± 0.039
48P (n = 6) P P sacrifice 0.098ad ± 0.008
24E+24P (n = 6) E2 P sacrifice 0.145abc ± 0.012
24P+24E (n = 6) P E2 sacrifice 0.170c* ± 0.018
  1. The rats were injected s.c. in the neck with either vehicle (propyleneglycol), 10 μg E2/kg rat, or 4 mg P4/kg rat, or combinations of these. Experimental animals were sacrificed after 24 or 48 hours of hormone treatment, respectively. The uterine wet weight is presented in grams (mean ± SD). Numbers (right column) without any common superscript letters indicate a significant (p < 0.05) difference in uterine weight. The asterisk (*) indicates a significant (p < 0.05) difference in uterine weight as compared to OvxC.
