한약이 난소제거 흰쥐와 SAM P6 생쥐의 골소주에 미치는 영향

The effects of herbal medicine on travecular bone area were studied using ovariectomized rat as an animal model of Type I osteoporosis and SAM P6 as that of Type II. We counted red blood cells(RBC), hemoglobin(Hb), and hematocrit(Hct) using Couter`sR method. Each traditional boiling water extract of Achyrathis Radix, Psoraleae Fructus, Rehmanniae Radix Preparat, and Cornii Fructus and a systemic water extract of Astragali Ractiex was given 5g/kg/day, p.o., for 30 days in a group of 4-5 ovariectormized rats. One ml of blood was taken by tail vein at day 0, 7, 14, 21, and 30 days after administration of the extract. The traditional hot water extract of Cervi parvumn Corni (Cervi) was given the same dose as described above for 14 days in a group of 10 SAM P6 mice and systemic water extract of Astragali Radix was administered as the same dose as above for 30 days in 10 SAM P6 mice. Travecular bone area was measured 5 mcm decalcified and stained thin bone slice by image analysis using a digitalizer. In Type I, ovariectomized rats, administration of Astragali Radix, Rhemanniae Radix Preparat, and Corni Fructus decreased in RBC, Hb and Hct. In Type II, administration of Cervi increased in RBC and Hct and that of Astragali Radix was also elevated RBC. In Type I, any administration of herbal medicine used in this study did not elevate travecular bone area significantly except Corni Fructus showed a trend of increase in travecular bone area. However, Type II, Cervi and Astragali Radix increased in both mean and total travecular bone area. Thus, there are significant difference in response of herbal medicine in different types of osteoporosis.
