Fig. 4From: Interplay between nitric oxide and gonadotrophin-releasing hormone in the neuromodulation of the corpus luteum during late pregnancy in the ratGanglionic effect of L-NAME on progesterone ovarian levels and luteal expression of 3β-HSD. A Ovarian progesterone release, expressed in ng/mg ovary. B Protein expression of the progesterone synthesis enzyme, 3β-HSD, expressed in arbitrary units. The progesterone release values represent the mean ± S.E.M. of 6 animals per experimental group and 3 animals per experimental group for 3β-HSD expression. Student’s unpaired t test: (∎) P < 0.001; (●) P < 0.01Back to article page
