The Response of Creatine Kinase Specific Activity in Rat Pituitary to Estrogenic Compounds and Vitamin D Less-Calcemic Analogs

Figure 1

Stimulation of creatine kinase (CK) specific activity by different estrogenic compounds in pituitary in immature female rats (a) and ovariectomized female rats (b). Rats were treated and assayed for CK activity as described in Section 2. Results are means ± SEM for 𝑛=5−15 rats/group. Experimental means compared to control means: ^∗𝑃<.05 and ^∗∗𝑃<.01. Basal activity in pituitary from intact rats was 1.12+0.17𝜇mol/min/mg protein and in Ovx rats was 0.47+0.02𝜇mol/min/mg protein.
