[Experimental steroid osteoporosis in rats and the way to restore the bone tissue structure].

Experimental prednisolone administration has been shown to cause osteoporosis in animals. A single administration of fetal tissue--10-day fetal homogeneous tissue at a dose of 0.5 mg into the experimental animal femur improves the bone tissue structure, hastens its remodeling, contributes to elimination of the bone tissue pathologic process in osteoporosis.
