Neutron activation analysis was employed to determine total body calcium in C3H/St(Ha) female mice. As 99% of body calcium is in bone, loss of calcium was used as an index of bone loss (osteoporosis). Heparin (500 U/kg b.i.d. caused bone loss in 3 months. Premarin (2 mg/kg q.d.) or norethindrone (40 mg/kg q.d.) alone prevented this osteoporosis. A Premarin-norethindrone combination (2 mg - 10 mg q.d. respectively) appeared to be somewhat more effective than either agent alone, but this difference was not significant at the 5% level. Combinations of estrogen and progestins may prevent metabolic bone disease at the same time reducing the danger of estrogen induced neoplasia.
