Interventions/Control_1 Following to administrate Methylprednisolone 1000mg/day intravenously slowly for consecutive three days, Prednisolone is administered orally for a maximum dose in 0.5mg/kg/day, then decreased gradually and terminated. There is a case to maintain the dose of Prednisolone by the degree of a progress of underlying disease.
Interventions/Control_2 Prednisolone is administered orally for a maximum dose in 0.5mg/kg/day, then decreased gradually and terminated. There is a case to maintain the dose of Prednisolone by the degree of a progress of underlying disease.
