[Experimental studies on the castration osteoporosis in the rat. II. Behavior of bone minerals].
In Wistar rats the bone mineral content of calcium magnesium, phosphor, sodium and potassium was investigated 10 months after complete ovarectomy. 20 of ovarectomized animals obtained in this time 0,65 mg ethinyloestradiolsulfonate/kg/month orally. The ovarectomy decreased significantly the content of calcium and magnesium of femur, humerus, vertebra thoracis and lumbalis. After therapy with the oestrogen these minerals were increased, but not significantly. These results did not correlate with the degree of histomorphometrically established osteoporosis. Phosphor, sodium and potassium were not changed significantly. The role of oestrogen dosis was discussed.
