Fluoride Action Network


Total skeletal calcium levels were determined in female mice with the aid of whole body neutron activation analysis. Three months treatment with heparin produced significant osteoporosis in C3-H/St(Ha) mice but not in C57/BL6 (J) mice. Treatment with a conjugated natural estrogen preparation (Premarin) prevented heparin accelerated osteoporosis, but high level fluoride in the drinking water had no preventive effect. In some experiments there was a suggestion of a deleterious effect of fluoride.
