In previous studies we reported that the levels of RBC, hemoglobulin (HGB) and hematocrit (HCT) in SAM P6 were increased significantly from 7 day after oral administration of the pilose antler extract, 5 g/kg/day, and were lasted during the study. Thus, this study was performed to elucidate mechanism of erythropoietic action by the extract administration. SAM R1 and SAM P6 were chosen as experimental animals. At age of 12 weeks, pilose antler extract were given 0.3 and 5 g/kg/day (p.o.) each for 0, 7 and 14 days in both animals. Complete blood cells such as RBC, HGB, and HCT were counted. And plasma concentration of erythropoietin (EPO) which is the major regulator of erythropoiesis was measured using $^{125}I-antierythropoietin$ IgG. Total iron concentration in plasma was also analyzed. The levels of RBC and HCT were increased significantly after administration at both doses of 0.3 and 5 g/kg/day in SAM P6, however, these were increased only at dose of 5 g/kg/day in SAM R1. The plasma EPO concentration was increased significantly after administration in SAM P6. The plasma concentrations of total iron were significantly decreased after administration of the extract in SAM P6. These results suggest that the changes in erythropoietic effects after the administration of pilose antler extract may be mediated, at least in part, through the change in the plasma EPO.

In previous studies we reported that the levels of RBC, hemoglobulin and hematocrit in SAM Rl and SAM P6 were increased significantly from 7 day after oral administration of the pilose antler extract, 5g/kg/day, and were lasted during the study. Therefore, this study was performed to elucidate mechanism of erythropoietic action by the extract administration. SAM Rl and SAM P6 were chosen as experimental animals. At age of 12 weeks, pilose antler extract were given 0.3 and 5 g/kg/day (p.o.) each for 0, 7 and 14 days in both animals. Complete blood cells (CBC) such as WBC, lymphocytes, monocytes, granulocytes, RBC, hemoglobulin, and hematocrit were counted. And plasma concentration of erythropoietin (EPO) which is the major regulator of erythropoiesis was measured using $\^$125/I-antierythropoietin IgG. Ferritin concentration in plasma was also analyzed.

This study was performed to investigate the modifying effect of the general (GPA) and the fermented pilose antler (FPA) on experimental hepatocarcinogenesis and Natural Killer cell activity in rats. Specific pathogen free, 5-week male Sprague-Dawley rats were divided into four groups. To induce hepatocarcinogenesis, diethylnitrosamine (DEN, 200 mg/kg, i.p.) was used as a tumor initiator and was given in a single dose at experimental onset. All rats were given a partial hepatectomy (PH) at 3 weeks after experimental onset. Sodium phenobarbital (PB, 0.05% in diet), GPA (0.075% in diet) and FPA (0. 075% in diet) were given from 2 to 8 weeks. Group I of the initiation control group was only given DEN. As initiation-promotion group, Group II was given DEN and then PB. Group III and IV were given DEN-PB-GPA and DEN-PB-FPA, respectively. In hematological analysis, as compared with Group I. the number of white blood cells were significantly increased in the GPA (p<0.01) and the FPA treated group (p<0.05), respectively. Natural killer (NK) cell activity by flow cytometer (FCM) analysis was higher in group of treated with the GPA (35%) than that of the FPA (27.5%), but not significant. Result of the immunohistochemical staining of the glutathione S-transferase placental form (GST-p) indicated that the number of and area of the pre-neoplastic lesions was not significantly changed in Group III and IV compared Group II, respectively. In conclusion, the GPA and the FPA treatment significantly increased the number od WBC in peripheral blood, but the enhancing NK activity and the modifying effect on the experimental hepatocarcinogenesis were not observed.

Objectives : The effects of water extract of deer antler herbal-acupunture solution(DHS), prepared from the pilose antler of Cervus korea TEMMINCK var. mantchuricus Swinhoe (Nokyong), a traditional immunosuppressive and immune-activating Korean herbal- acupuncture, on collagen-induced arthritis(CIA:RA model) in mice was studied. Destruction of cartilage and bone are hallmarks of human rheumatoid arthritis, and controlling these erosive processes is the most challenging objective in the treatment of RA. Methods : We investigated the tissue protective effects of deer antler treatment using established murine collagen-induced arthritis(CIA) as a model. Potential synergy of low dosages of anti-inflammatory glucocorticosteroids and deer antler was also evaluated. Results : Treatment of established murine CIA with deer antler herbal-acupunture solution(DHS) $(10-50{\mu}g/day)$ suppressed disease activity and protected against cartilage and bone destruction. Although $10-50{\mu}g/day$ DHS had only a moderate effect on the inflammatory component of the disease activity, it strongly reduced cartilage pathology, as determined by histological examination. Serum cartilage oligomeric matrix protein(COMP) levels were significantly reduced, confirming decreased cartilage involvement. Histological analysis showed that bone destruction was prevented. DHS administration increased serum IL-1Ra levels and reduced anticollagen type II antibody levels. Treatment with low-dose $DHS(1{\mu}g/day)$ was ineffective in suppressing disease score, serum COMP or joint destruction. Synergistic suppression of both arthritis oseverity and COMP levels was noted when low-dose DHS was combined with prednisolone(0.05mg/kg/day), however, which in itself was not effective. Conclusion : DHS was shown to have the inhibiting effects against $IL-1{\alpha}-$ and $IL-1{\beta}-stimulated$ bone resorption. These results indicated that the DAS is not only highly stable and applicable to clinical uses in bone resorption, but also it will be served as a potent anti-inflammatory and anti-arthritic agents for treatment of human RA.

Objectives : Deer antler Water Extract(DAE), prepared from the pilose antler of Cervus korean TEMMINCK var. mantchuricus Swinhoe (Nokyong), a traditional immuno-suppressive and immuno-activating Korean herbal-acupuncture, is thought to play an important role in human bone remodeling. Methods : To determine whether DAE can induce the differentiation of resting zone chondrocytes(RC) or not, confluent cell cultures were pretreated for 24, 36, 48, 72, and 120hrs with DAE. At the end of pretreatment, the media were replaced with new media containing $10^{-10}{\sim}10^{-8}M\;1,25-(OH)_2D_3$ and the cells incubated for an additional 24hrs. Results : This second treatment was chosen because prior studies had shown that only the more mature growth zone chondrocytes(GC) respond to this vitamin $D_3$ metabolite. The effect of DAE pretreatment on cell maturation was confirmed by measuring alkaline phosphatase (ALPase)-specific activity. Changes in matrix protein synthesis were examined by measuring collagen synthesis, as well as $^{35}SO_4$ incorporation into proteoglycans. When RC cells were pretreated for 120h with DAE, treatment with $1,25-(OH)_2D_3$ caused a dose-dependent increase in ALPase-specific activity and collagen synthesis, however, the proteoglycan production was not affected. RC cells pretreated with $1,25-(OH)_2D_3$ responded like RC cells that had not received any pretreatment. Conclusion : These results indicate that DAE directly regulates the maturation of RC chondrocytes into GC chondrocytes. Therefore it was indicated that DAE may play a significant role in regulating chondrocyte maturation during endochondral ossification.

Objectives : The effect of water extract of the pilose antler of Cervus korean TEMMINCK var. mantchuricus Swinhoe (Nokyong), a traditional immuno-suppressive and immuno-activating Korean oriental medicine, on collagen-induced arthritis (CIA) mice model was studied. Identification of common Nokyong capable of affording protection or modulating the onset and severity of arthritis may have important human health implications. Methods : Nokyong has shown to possess anti-inflammatory and anticarcinogenic properties in experimental animals. In this study we determined the effect of DAE on collagen-induced arthritis in mice. Results : In three independent experiments mice given DAE in water exhibited significantly reduced incidence of arthritis (33% to 50%) as compared with mice given no DAE in water (84% to 100%). The arthritis index also was significantly lower in DAE-fed animals. Western blot analysis showed a marked reduction in the expression of inflammatory mediators such as cyclooxygenase 2 (Cox-2), $Interferon-{\gamma}\;(INF-{\gamma})$, and tumor necrosis factor ${\alpha}\;(TNF-{\alpha})$ in arthritic joints of DAE-fed mice. The neutral endopeptidase (NEP) activity was approximately 6-fold higher in arthritic joints of non-DAE-fed mice in comparison to nonarthritic joints of nonimmunized mice whereas it was only 2-fold higher in the arthritic joints of DAE-fed mice. Additionally, total IgG and type II collagen-specific IgG levels were lower in the arthritic joints of DAE-fed mice. Conclusion : Taken together our studies suggest that DAE may be useful in the prevention of onset and severity of arthritis.

본 실험에서는 녹용 약침액의 항 골재흡수 속성을 조사하였다. PTH, $1,25(OH)_2D_3$와 IL-1을 각각 골재흡수 인자로 사용하여 생쥐의 두개골에서 osteoblast 세포를 격리, 배양, 그리고 자극시켰을 때 collagenolysis의 증가를 보였다. 두 가지를 동시에 사용한 결과, IL-1은 골재흡수성을 촉진시키고 재 흡수력을 생산하였다. In vitro에서의 세포독성 결과는 $1-200{\mu}g/ml$의 녹용 약침액 농도 분포에서 무세포독성을 보였다. 또한 녹용 약침액은 생쥐의 두개골 골아세포 내에서 PTH (2 unit/ml), IL-$1{\alpha}$ (1 ng/ml), $1,25(OH)_2D_3$ (10 ng/ml), IL-$1{\alpha}$ 및 IL-$1{\beta}$로 인해 유발된 collagenolysis에 대해서 대항하는 보호활동성을 나타내었다. 녹용약침액은 IL-$1{\alpha}$ 와 IL-$1{\beta}$로 인해 유발된 collagenolysis에 대항하는 보호활동성을 지녔다. DAS는 IL-$1{\alpha}$와 IL-$1{\beta}$로 인해 촉진된 골재 흡수력을 억제하는 효과를 보였다. 이와 같은 결과는 녹용약침액이 골다공증과 연관된 질환에 대해서 매우 안정적인 임상적 사용이 가능한 것을 관찰할 수 있으므로 추후 이와 관련한 지속적인 연구가 필요할 것으로 사료되었다.

The water extract of pilose antler of Cervus nippon var. mantchuricus (WEC) was investigated in respect of its effect on ceruloplasmin and $\alpha$$_1$-cysteine protease inhibitor (CPI), which are acute-phase proteins showing increased synthesis following inflammatory stimulus in rat. Ceruloplasmin and CPI were spectrophotometrically determined by the oxidase activity and the inhibitory activity on papain, respectively, and their changes in the concentrations in plasma or serum were examined after oral administration of 0.04% WEC to rats during 7 days following inflammation by subcutaneous injection of turpentine oil or lipopolysaccharide (LPS). WEC suppressed the maximum increases in ceruloplasmin and CPI on the 4th day after injection of turpentine oil, but the suppression in ceruloplasmin was more potent than that in CPI. On inflammation by LPS the suppression of the maximum increase in ceruloplasmin by WEC was found on the 2nd day, but the result was less significant from that obtained by the treatment with turpentine oil. Administration of WEC for at least 4 days was required to suppress the maximum increase in ceruloplasmin due to inflammation by turpentine oil. When WEC was administered to rats after injection of turpentine oil, a high dosage (0.36% of WEC) was requisite for the suppression on the maximum increase in ceruloplasmin.

Aging process can be explained by many factors. In this study, we counted complete Blood Cells (CBC) such as WBC, Lymphocytes, Monocytes, Granulocytes, RBC, HGB, and HCT of both SAM P6 and SAM P1 during the aging process. Plasma albumin, glucose, alkaline phosphatase, calcium, creatinine, inorganic phosphate, urea concentrations were also measured at the same time. In addition to these, plasma concentrations of cortisol, total T3, and total T4 were analyzed by Chemiluminescent Immunoassay. There were no change in CBC counts of SAM R1 and SAM P6 during this study. Plasma concentratins of albumin and glucose decreased significantly in SAM R1. However, plasma alkaline phosphatases and creatinine concentration in SAM P6 decreased significantly at 16 week after birth comparing to the control. Total T4 levels were siginificantly increased although cortisol and total T3 concentrations were the same in SAM R1 groups. Especially, the after birth of creatinine, alkaline phosphatase, T4 of SAM P6 at 16 week were significantly different form those of SAM R1. At 12 week after birth, pilose antler extract was given 5g/kg/day p.o. for 0, 7, 14, 21, and 30 days each in both SAM R1 and SAM P6. The RBC, HGB, and HCT levels started to increase significantly from 7 days after the dose at SAM P6 only. Total T4 conectrations were elevated gradually during the study although the antler extract administration did not prevent or inhibit the increase in total T4 concentration during the study. Therefore, the elevation of erythrocytes after administration of the extract needs to be studied in future.
