[Functional state of calcitonin-producing cells of the female rats' thyroid as a result of experimental osteopenia therapy by graduated support loading combined with oestrogens and calcitonin injection].

: Effects of graduated (2-hr.) support loading, synestrol and myocalcic on the thyroid C-cells was evaluated with the immunocytochemistry and cytomorphometry techniques. Graduated support loading was shown to partially recondition degraded functioning of C-cells. Synestrol injection suppressed the stimulating effect of support loading; myocalcic had a little effect on the C-cell activity. Simultaneous injection of two substances cancelled out the stimulating effect of support loading.
