Those rabbits in TTG were treated with three-period treatment. Those in OTG were treated with one-period treatment. Those in PTG were feed by guzhecuoshangsan, a Chinese patent medicine which is used to treat bone fracture. Those in model control group were given no prescription or drug but distilled water as same dose as that of other groups.
