Results 
The osteoarthropathy scores significantly decreased after vitamin E administration (p=0.0243), while serum-estradiol concentrations did not change. The serum-estradiol concentrations before vitamin E administration in the group sensitive to the vitamin E efficacy were significantly lower, as compared with those in the insensitive group (p=0.0005).
