본 연구는 녹용 추출물이 scopolamine으로 기억손상을 유발한 실험동물의 기억력 개선과 AChE, MAO-B의 활성억제, 신경전달 물질인 ACh 함량을 치매 치료제인 tacrine과 비교하여 분석하였다. 공간인지력을 평가하는 Morris water maze test에서 scopolamine(2 mg/kg, i.p.)으로 기억손상을 유발한 경우 4일간의 인지훈련에도 불구하고 platform을 찾아가는 escape latency 시간이 증가되었으며, tacrine과 녹용추출물 투여군은 훈련 2일째부터 유의적으로 escape latency 시간이 감소하였다. 실험 5일째 platform을 제거한 probe test에서도 녹용 추출물 처리군은 scopolamine 처리군보다도 escape latency 시간이 유의적으로 감소하여 장기기억 개선효과가 있음을 보여주었다. 뇌의 신경전달물질인 ACh 생성은 대조군 대비 scopolamine 투여군은 84.7% 감소하였으나, 녹용 추출물 투여군(97.5%)은 치매 치료제인 tacrine(97.8%)과 비슷하게 정상적인 수치로 ACh 생성량을 증가시켰다. Tacrine 처리군은 scopolamine 투여로 상승한 뇌조직과 혈청의 AChE 활성을 유의적으로 감소시켰고, 녹용 추출물 처리군은 뇌조직의 AChE 활성을 유의적으로 감소시켰다. 뇌조직의 MAO-B 활성은 그룹 간 유의적인 차이는 없었으나, tacrine과 녹용 추출물 처리군이 scopolamine 투여군보다 MAO-B 활성을 감소시키는 경향을 보였다. 따라서 녹용 추출물은 scopolamine으로 기억손상을 유발한 치매 동물모델에서 신경전달물질을 분해하는 효소의 활성을 저해함으로써 장기기억 활성을 촉진하고 콜린성 신경계를 자극하여 기억 및 학습 증진에 효과적으로 작용하는 천연물 유래 기능성 물질로 사료된다.

The quality characteristics of velvet antlers obtained from Formosan sambar deer (Cervus unicolor Swinhoi) (SDVA), harvested from 63 to 81 d during the velvet antler growth period, were evaluated by investigating the relationships between antioxidant levels; including content, activity, and content/activity ratios, and physical properties; including shear force values, color, and Ca content. The hardness of samples from base velvet antler sections increased, and that the color of these samples tended to become reddish-yellow (redder and more yellow), suggesting that the Ca content in the base section of the sample was not ossified yet. Samples from the upper sections of velvet antler showed higher superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPX) content (3.91 to 1.50 mg/mL, 2.53 to 0.90 mg/mL, and 3.95 to 1.58 mg/mL, respectively) than did samples from the middle and base sections (p<0.05). The activity and content/activity ratios of GPX measured in the upper section were also found to be significantly greater than in the middle and base sections (p<0.05). We further observed that the content and activity of GPX was significantly and negatively correlated with Ca content, shear force values, and the content/activity ratio of this antioxidant (p<0.01). The study findings may serve as a reference index for quality evaluations of velvet antlers of Formosan sambar deer in future.

Although it has traditionally known that deer antler and medicinal herbs extract contain some functional components for health promotion, the nutritional significance remains to be elucidated. This study examined the efficacy of deer antler extract (DA) , medicinal herbs extract (MH) and their mixture (DAMH) on serum IGF-I, bone growth with growing rats in vivo and splenocyte proliferation with spleen cells in vitro. Three week-old young female rats (Sprague-Dawley) were divided into 4 groups and then fed basal diet (AIN-93G) or experimental diets containing DA, MH, DAMH, respectively, for 7 weeks. We collected blood, liver, kidney, spleen, femur and tibia from rats. There was no significant difference in weight gain, but food intake increased in DA- and MH-fed groups. There were no signs of liver and kidney damage in the DA, MH and DAMH-fed groups compared to basal diet group. In femur and tibia, wet weights: breaking forces and bone minerals (Ca, Mg and Zn) were significantly higher in the DA-fed group than in the other groups. Serum alkaline phosphatase (ALP) , bone-specific alkaline phosphatase (BALP) activities were significantly lower in the DA, MH, DAMH-fed groups than in basal diet group. Also, serum insulin-like growth factor-I (IGF-I) concentrations were significantly increased in DA-fed group compared to the other groups. Therefore DA was shown to have an activity of bone growth promotion by increasing the IGF-I, a major bone growth factor. The deer antler extract showed an enhanced immune action on the primary cultured-cells from spleen of rats, representing that splenocytes were proliferated by lipopolysaccharide (LPS), but not by concanavalin A (Con A). These results indicate that deer antler extract has beneficial effects on bone growth via IGF-I and on splenocyte activation.

Serum biochemical values were measured in blood samples collected from 8 fasted stags from both jugular and femoral veins at 18-day intervals during antler growth. Samples were analyzed for blood substrate, enzyme activity values, minerals and electrolyte. There were no significant differences in total protein, albumin, urea, creatinine, triglyceride, glucose or cholesterol concentration between veins or sampling dates. However, total-bilirubin concentration in the jugular vein on the casting date was three times higher than on the other sampling dates (p<0.05). There were no significant differences in alkaline phosphatase, aspartate aminotransferase, and alanine aminotransferase with progressing antler growth. The highest level of alkaline phosphatase concentration was on day 55 after casting. There were no significant differences in inorganic phosphorus, sodium and chloride concentration between jugular and femoral samples. Calcium concentration was significantly higher in the femoral vein on the cutting date (55 day) than in the jugular vein (p<0.05). There were few changes in serum biochemical values. However, some electrolytes and minerals had differences during antler growth. It is suggested that despite such a big event as antler growth, blood biochemical values are not variable if feeding conditions are consistently maintained as was the case in this study.

Antlers from deer species are alternative animal by-products. Due to the oriental trade, the velvet antler industry is rapidly emerging in North America. The unique biological property of antler wish a deciduous natural phenomenon offers the valuable model of biomedical research. Growing antlers showed different structures according to cell populations consisting of mesenchymes, chondroblasts, chondrocytes and osseous tissues from distal to proximal portions of main beam. Their structures were different from two tissues, cartilage and bone, in growing antlers. Zone of maturing ants calcifying chondrocytes referred as upper section was invaded by osteoblasts indicating the occurrence of endochondral ossification. The cartilaginous tissues were gradually replaced by osseous tissues downward. The bony tissues referred as the middle and base sections in this thesis contained spongy bone and cortical bone structure in the difference of the degree of mineralization antral the thickness of cortical bony in adjacent to outer velvet layer. In addition, the endocrinological regulators such as testosterone, prolactin, growth hormones and other growth factors are actively involved in the unique deciduous nature shown in the growth and development of antler.

사슴뿔은 동물세계에서 가장 빨리 성장하는 조직이다. 따라서 성장중인 사슴뿔은 뼈 성장을 촉진하는 인자가 풍부하게 포함된 것으로 생각된다. 이들 성장인자들 중 IGF-1은 뼈를 자라게 하는 조골세포의 대사에 중요한 역할을 한다고 알려져 있어 이를 정제하고자 하였다. IGF-1의 정제는 상대라고 불리는 신선한 사슴뿔을 유안침전, DEAE-Sepharose CL-6B 이온교환수지, CM-Sepharose CL-6B 양이온교환수지, Sephadex G-50의 순차적인 방법으로 할 수 있었다. 각 과정마다 IGF-1의 거동을 HPLC, SDS-PAGE, Dot blot, 그리고 western blot으로 분석하였다. IGF-1의 정량은 ELISA기술로 재조합 인간 IGF-1을 이용하여 계산되었으며, 최종 분별 액은 두 개의 단백질을 보였으나, Western-blot에서 작은 분자량인 12 kDa으로 최종 판명할 수 있었다. 정제된 단백질은 HPLC에서 retention 시간 8분만에 검출되었으며, 총 농도는 2910 ng/ml 이고 중량은 0.291 g 이었다.

The process of wound repair involves an ordered sequence of events such as overlapping biochemical and cellular events that, in the best of circumstances, result in the restoration of both the structural and functional integrity of the damaged tissue. An important event during wound healing is the contraction of newly formed connective tissues by fibroblasts. The polypeptide growth factors, like transforming growth factor-${\beta}$(TGF-${\beta}$, insulin-like growth factor I (IGF- I) and epidermal growth factor (EGF), play very important mediator roles in the process of wound contraction. Deer antlers, as models of mammalian regeneration, are cranial appendages that develop after birth as extensions of a permanent protuberance (pedicle) on the frontal bone. Antlers contain various growth factors which stimulate dermal fibroblast growth. They are involved in digestion and respiration and are necessary for normal wound healing and skin health. In order to investigate and evaluate the effects of red deer antlers on skin wound site, the speed of full-thickness skin wound healing and the expression of IGF-I, TGF-${\beta}$ and EGF in skin wounds, three groups of skin full-thickness rat models with a high concentration of antler ointment, a low concentration of antler ointment and without antler ointment were compared. At post-injury days 0, 2, 4, 8, 16, 20, 32, 40 and 60, the skin wound area was measured, the expressions of IGF-I, TGF- ${\beta}$ and EGF mRNA were detected by reverse transcriptase polymerase chain reaction (RT-PCR) and collagen formation by sirius red dye and the localization of IGF-I, TGF-${\beta}$ and EGF peptides were inspected by histological immunohistochemical techniques. Wound healing was significantly more rapid in antler treated skins. In addition, the wound treated with a high concentration antler ointment, a low concentration antler ointment, and the control closed completely at post-injury day 40, day 44 and day 60, respectively. Via RT-PCR, the expressions of IGF-I (day 8 and day 16), TGF-${\beta}$(day 8, day 16 and day 20) and EGF (day 4, day 8, day 16, and day 32) were obviously up-regulated in high concentration antler-treated skins compared to control skins. Similar results could be seen in the histological detection of collagen dye and immunohistochemical methods using the corresponding polyclone antibodies of IGF-I, TGF-${\beta}$ and EGF. These results illustrate that antlers stimulate and accelerate the repair of cutaneous wounds.
