title: [Comparison of effects of Wujia Bugu decoction) and alendronate sodium on protection the bone loss of hindlimb unloaded rats].
abstract: OBJECTIVE
  To compare the effects of Wujia Bugu decoction and Alendronate sodium on protecting bone and muscle loss of hindlimb unloaded rats lasting three weeks.
  
  
  METHODS
  March to May, 2009, 40 male Wistar rats with age of 6-week, were randomized divided to four groups (10 rats in each group): hindlimb unloaded group treated with Chinese medicine (HUC), hindlimb unloaded group treated with alendronate sodium (HUA), control group (CON), as well as hindlimb unloaded group (HU). During the experiment, rats of HUC was given Wujia Bugu decoction (including the Ciwujia, Shudihuang, Huainiuxi, Muli, etc. with the concentration of 0.704 g/ml) 10 ml/kg weight once a day, HUA was given quantitative alendronate sodium slice dissolve suspension (0.9 mg/ml) once a week. CON and HU were given double-distilled water. The experiment lasted 4 weeks,from the second to the forth week, rats in HU, HUC, HUA were hindlimb unloaded. All rats were sacrificed at the fourth weekend, the content of Ca, P and the activation of ALP in serum, Bone mineral density (BMD) of humerus and femurs, Biomechanical property of tibia and humerus, as well as the weight index of biceps and sural muscles were measured.
  
  
  RESULTS
  Compared with CON, serum Ca of HU was significantly increased (P < 0.05), BMD, mechanical properties, muscle index of hindlimb were significantly reduce (P < 0.01), the serum Ca of HUA significantly increased (P < 0.05). Serum ALP of HUC was significantly higher than other three groups (P < 0.01). Compared with HU, femoral BMD of HUC and HUA significantly increased, tibial maximum load, maximum deflection and elastic load had increased tendency; calf muscle atrophy of HUC and HUA was alleviate 50% and 12.5% respectively (P > 0.05), humeral BMD had no significant difference, while the maximum deflection (P < 0.01) and elastic deflection (P < 0.05) in humerus of HUA were significantly lower.
  
  
  CONCLUSIONS
  Herbal prescription and alendronate sodium can effectively protect the bone and muscle loss of hindlimb unloaded rats, improve its mechanical structure. Herbal prescription has advantages of relieving mechanical properties change. The effects of Wujia Bugu decoction and alendronate sodium are similar in treating space weightlessness bone loss.
