Studies on osteoporosis. II. Effect of estrogens and fluoride on experimental osteoporosis. A preliminary report

Total skeletal calcium level was determined in female mice with the aid of whole body neutron activation analysis. Three months treatment with heparin produced significant osteoporosis in C3H/St(Ha) mice of 3--5 months of age. Treatment with a conjugated natural estrogen preparation (Premarin) prevented this phenomenon but high level fluoride in the drinking water failed to show preventive activity.
