Abstract:
BACKGROUND: Shuangshen oral liquid consisting of renshen and danshen is firstly used to treat glucocorticoid-induced osteoporosis. OBJECTIVE: To establish a rat osteoporosis model through glucocorticoid and to observe the preventive effects of shuangshen oral liquid (SS) on bone substance and bone mass. DESIGN, TIME AND SETTING: A completely randomized controlled grouping animal experiment was performed in the Animal Experimental Center and Department of Pharmacology, Guangdong Medical College from June to September in 2008. MATERIALS: High-dose SS consisted of 3.6 kg danshen, 5 kg renshen, and then prepared by water extraction twice, and the concentration was 870g/L. On this basis, high-dose SS was diluted three times to obtain low-dose SS with a concentration of 290 g/L. The prednisone acetate raw medicine was purchased from Zhejiang Xian Ju Pharmaceutical Co., Ltd. METHODS: Thirty-two 3-month-old male SPF rats were randomly divided into 4 groups, and every group had 8 rats. The normal control group rats were fed with distilled water 5 mL/(kg?d) by gavage. Rats in prednisone group were treated with 0.7 g/L prednisone suspension (5 mL/kg per day) by gavage. SS group rats were treated with 0.7 g/L prednisone suspension (5 mL/kg per day) by gavage and then given the high does and low does SS (5mL/kg per day) respectively by gavage 3 hours later. The rats were sacrificed by heart hemospasia 88 days later. MAIN OUTCOME MEASURES: Body mass, bone mineral content and bone hydroxyproline content per unit bone, bone mineral density in the left femur, biomechanics indexes of the right femur. RESULTS: The long-term administration of prednisone restrained the increasing of rats body mass (P
