SAM p6 mouse에서 자하거 주사제의 골다공증 개선에 대한 연구

Effects on osteoporosis of Senescence Accelerated Mice (SAM) P6 by Injection of Placenta extracts ($Beuronel^{(R)}$)

Objectives : The purpose of this study was to examine the effects of the Hominis placenta extracts on improvement of senile osteoporosis (Type 2) in SAM P6. In traditional Oriental medicine, Placenta (Jahageo) is indicated for insufficiency of blood and tidal fever due to steaming bone disorder. Methods : At 10 weeks after birth, Placenta ex. was given 100 mL, 200 ml/kg/day, i.p. 3 times a week for 4 weeks in SAM P6 mice. And then we measured complete blood cells, blood urea nitrogen, creatinine, inorganic phosphate and total iron. In addition, we tested bone mineral density (BMD) using the soft X-ray. Results : As a result, in SAM P6, injection of Placenta ex. (200 mL) increased in RBC, HB and PLT, in comparison with control group. It was also found that the inorganic phosphate levels increased significantly in the injection groups of the Placenta ex. from that of the control group, but blood urea nitrogen was no significant. Moreover, Placenta ex. were showed a trend of increase in bone mineral density (BMD) of the vertebrae lumbales and tibia in P6 mice. Conclusions : These findings suggest that Placenta ex. are effective in preventing bone loss in SAMP6.
