Figure 3From: Increases in norepinephrine release and ovarian cyst formation during ageing in the ratChanges in corpus luteum, luteinized follicles in the ovary and in progesterone during aging in the rat. (A) represents number of corpus luteum, (B) represents number of luteinized follicles in the ovary and quantified as it was described in methodology section and (C) serum level of progesterone during aging in the rat measured by EIA. Results are mean value ± SEM of n = 4 experiments. a = p < 0.001 vs. 6, 8, 10 months, b = p < 0.001 vs. all groups; c = p < 0.01 vs. 8 months; c = p < 0.05 vs 6 months; e = p < 0.01 vs 10 months.Back to article page
