[A study on observation of bone metabolism in middle-aged and senile female Graves' disease]

Sixty-nine cases of middle aged and senile female Graves' desease (GD) patients suffered from abnormal bone metabolism have been studied. They were divided randomly into group A and B, treated separately with antithyroid drugs (Tapazol and inderal, etc.) in group A, and added with Chinese herbal medicine for tonifying Kidney and promoting blood circulation in group B. Before treatment, patients of both groups showed obvious higher blood calcium (Ca) 24-hour urinary Ca, phosphorus (P) and serum clcitonin (CT) levels than that in normal subjects. These patients' serum Ca, moreover, had a parallel relationship with serum T3 levels (r = 0.6142, P < 0.01) and the serum Ca also a paralleled with serum CT levels (r = 0.5714, P < 0.05). After six months of treatment, the serum Ca, 24-hour urinary Ca, P and blood CT values were all reduced in various degree. The decrease of these bone metabolic parameters were more significant in group B than that in group A.
