우리나라 양록업의 역사는 길지 않지만, 양록 생산물의 하나인 녹용은 전 세계 유통 물량의 80%정도를 차지하는 최대 소비국이며, 양록 생산액도 약 2,000억원 상당에 이르고 있다. 우리나라에서 녹용에 관한 연구가 시작된 시기는 대략 1970년대 중반 이후로 알려졌으나, 그 동안의 연구는 녹용의 약리적 효과만을 중점적으로 다루었다 해도 과언이 아니다. (중략)

알려진 녹용의 효능을 과학적으로 증명하고 활성성분을 이용하여 신의약품 개발에 기여하고자 한다. 본 연구실에서는 녹용의 가장 대표적인 효능인 조혈작용을 하는 성분을 구조 분석하여 MADG임을 밝히었다. MADG는 조혈촉진기능뿐만 아니라 대식세포 증식기능 그리고 비장세포성장을 촉진하는 등 면역활성 조절제로써의 기능도 나타내었다. 그리고 녹용에 존재하는 인지질 중에서 포화지방산을 가지고 있는 phophatidylcholine도 면역활성을 촉진시키었다. 항진균작용을 하는 성분을 구조 분석한 결과 lysophophatidylcholine임을 밝히었으며 그 유도체인 CHJ-ester가 숙주세포에는 해를 주지 않으면서 항진균작용을 하는 것을 관찰하였다. 그리고 골다공증치료효과를 검색하기 위해 녹용 정제성분으로 연구한 결과 파골세포로의 분화를 100$\%$ 저해함을 밝히므로 녹용이 골다공증 치료효과가 있음을 증면하였다. 녹용성분의 유도체인 SCOH가 파골세포분화를 억제함을 밝혀 현재 골다공증치료제로써의 가능성을 조사하고 있다. 본 연구실에서는 1999년부터 녹용연구를 시작하여 현재까지 10여 개의 활성성분을 분석한 바 있다. 현재 조혈세포촉진작용, 면역증진작용, 골다공증치료작용, 대식세포 증식작용, 항진균작용, 항간질작용에 대한 성분 분석 및 그 약리 기전을 연구하고 있다.

In this study, current status of domestic deer farms and its feeding were surveyed. The information of supply and demand of feed f3r deers including its industry were also examined and then analyzed to make fundamental data for deer farms and government policy. The results are as follows. 1. Over 40 years old farmers were about 63％ of total deer farms while 20­30 years olds were less than 1％ indicating that young people still evade agriculture. Moreover, considering education, over 52％ of the farmers have bachelor degree showing much higher rates compared to the other agricultural fields. The reason can be assumed that the labor burden is not serious in deer farming while it is not dirty job compared to the other livestock management. Those high­educated people can be easily trained as experts of deer farming to improve its international competition. 2. Most of investigated farms raise Korean spotted deers and Elk showing that the percentage of Elk has greatly increased(However, many farmers have complained about purchasing methods and they insisted that the sales organization should be controlled by government). 3. 57％ of total cost of production is for feed while most of feeds are imported from abroad. It indicated that it is urgent to make counterplan for saving feed cost. 4. It is necessary to develop feeds for deers in the near future while most of the examined farmers currently use normal assorted feed. Typical roughage sources feeds are rice straw, alfalfa hay, browses feed, and so on. Most of them are currently imported except the rice straw indicating urgently needed to develop domestic bulky feed. 5. The present questions are development of processed goods of velvet antler, establishment of reasonable management system, difficulty of velvet antler selling, feed supply, and so on. It is necessary for government and academic world to develop reasonable policy and scientific research program.

This study was performed to evaluate the effect of succinylcholine chloride as a muscular relaxant in deers. Succinylcholine chloride was administered for the harvesting of velvet antler to 62 sika deers which were farmed in the surburb of Seoul. The results obtained were as follows. 1. The more the dose of succinylcholine the earlier the time to immobilization and the slower the time to recover (p<0.05). 2. The optimal intramuscular dose of succinylcholine was found to be 0.11~0.14mg per kg of body weight for sika deer. 3. The time to immobilization revealed the longest An 4~6 years group. The more the age the longer the time to recover (p<0.05).

This study was undertaken to measure changes in the composition of elk velvet antlers, by considering the part and growth days (40th day, 60th day). The collected samples were divided into the tip, upper, middle, and base part by position. Samples were analyzed for moisture, crude protein, crude fat, crude ash, crude fiber, pH, minerals, and fatty acid and amino acid contents. The amounts of crude protein and crude fat were determined to be highest at the tip of the velvet antler by position, whereas dry matter and crude ash were high at the base. Crude protein contents were increased in the upper part but were decreased at the base, when assessed by growth day. Conversely, crude fiber and crude ash were found to be increased at the base by growth day. The pH value was determined to be lower at the tip, but did not differ when evaluated by growth day. Mineral contents (Ca, P, K) differed significantly by growth day in the middle portion of the antler. Saturated fatty acids tended to increase by growth day, whereas unsaturated fatty acids showed a decreasing trend. However, no significant difference was obtained for any of the components. Most amino acids were found to be high in the 60 days velvet antler, except isoleucine (Ile), which showed low levels at day 60. These results provide information on the changes in the composition of antlers, in cases of early cutting.

In this study, we examine the changes to Korean medicine that occurred when 'proprietary medicines' (賣藥) swept through the pharmaceutical market during the Japanese occupation (1910-1945 C.E.). Proprietary medicine during the Japanese colonial period took various forms including ready-made, over-the-counter, patent, and nostrum type pharmaceuticals. This paper examines how Korean medicine, which was the dominant form of medicine during the Joseon Dynasty, was forced to adapt to the rise of proprietary medicines. We found that the prescription of Korean medicine herbal decoctions became more like proprietary medicine in the way that they were formulated. In addition, prescriptions in Korean medicine books were reformulated with prescriptions and medicines from outside the tradition. Proprietary medicines, many of which were made with secret recipes handed down in a family, also attracted attention. Such prescriptions were made famous through advertisements and further influenced future Korean medicine doctors. New prescriptions took advantage of the trust and authority existing in traditional Korean medicine by introducing ginseng and traditional medicinal herbs such as deer antler velvet (鹿茸, Cervi Parvum Cornu). This paper argues that proprietary medicine of the Japanese colonial period distorted the concept of traditional herbal medicine.

This study was conducted to investigate the effect of supplementary feeding levels on livestck and forage productivity and grazing intensity in Elk stags (Cervus canadensis). A fifteen 2-year-old Elk stags about 195 kg were randomly assigned to one of three dietary treatments (five animals per treatment). The dietary treatments consisted of a feeding concentrate of 1.0% of body weight (T1), 1.5% of body weight (T2) and 2.0% of body weight. Total dry matter intake (TDMI) was increased with increased with an increasing supplementary feeding levels. Average daily gain (ADG) were significantly increased with an increasing supplementary feeding levels (p<0.05) and reached a maximum on July and was lower in spring than autumn. The velvet antler production was no differences among treatment groups. Forage productivity of pasture and crude protein content were highest on May and decreased thereafter, however, crude fiber content was the reversed. The grazing intensity of Elk stags was increased in spring (38 to 59 head per ha) than summer and autumn (13 to 32 head per ha). The average grazing intensity of Elk stags ranged from 21 to 34 head per ha, which is affected by supplementary feeding levels. This result suggests that feeding supplementary diet at 1.5 % of body weight was needed to maintain the stable wight gain in antler growing periods and control the proper grazing intensity of Elk deer stags.

Purpose : This study compares prescriptions in the 1901 edition of the Donguisusebowon (東醫壽世保元) and the 1901 edition of 24 Revised Tae-eum constitution prescriptions (新定太陰人病應用要藥二十四方) (1901PCDT) with medical herbs found in classical texts. This study also examines whether to include patterns which compose medical herbs for the person of Tae-eum constitution (太陰人). Method : The prescriptions for Tae-eum-in in the Shinchukbon and the ingredients of medical herbs of the prescriptions of the Complete Works of Zhang Jingyue (景岳全書), Secret Works of Universal Benefit (廣濟秘笈), Treasured Mirror of Eastern Medicine (東醫寶鑑), Comprised Edition for Formulas (方藥合編), Protecting Essence for Longevity (壽世保元), Introduction to Medicine (醫學入門), New Book for Saving People (濟衆新編 ENGLISH), and Compendium of Local Medicinals and Formulas (鄕藥集成方) were input into a database. The prescriptions were examined and combinations of medical herbs used to treat the person of Tae-eum constitution were noted. Result : Among the prescriptions for the person of Tae-eum constitution, similar examples of the 17 prescriptions of Kudzu Decoction to Relieve the Muscles (葛根解肌湯), Regulate the Stomach and Coordinate the Purity Decoction (調胃升淸湯), Clear the Heart and Lotus Pip Decoction (淸心蓮子湯), Decoction for Stabilizing Asthma with Ephedra (麻黃定喘湯), Profuse Heat and Sparse Cold Decoction (熱多寒少湯), Decoction for Coordinating Qi with Kudzu (葛根承氣湯), Major Decoction for Coordinating Qi with Kudzu (葛根大承氣湯), Minor Decoction for Coordinating Qi with Kudzu (葛根小承氣湯), Decoction for Dispersing the Exterior with Ephedra (麻黃發表湯), Boost the Lung Essence Decoction (補肺元湯), Major Supplementing Decoction with Deer Antler Velvet (鹿茸大補湯), Boosting Black Essence Pill (拱辰黑元丹), Honeylocust Fruit and Rhubarb Decoction (皂角大黃湯), Kudza and Duckweed Decoction (葛根浮萍湯), Sweet Flag and Polygala Powder (石菖蒲遠志散), Liriopis and Polygala Decoction Powder (麥門冬遠志散), and Cattle Gallstone Formula to Clear the Heart (牛黃淸心元) were found in important ancient literature and Dried Chestnut and Holotrichia Decoction (乾栗蠐螬湯) and Dried Chestnut and Tree of Heaven Root Bark Decoction (乾栗樗根皮湯) are the combination originally set by Lee Jema. Conclusion : Because 70.8% of the prescriptions in 1901PCDT could be found in literature which were pervasive in the period of the Joseon Dynasty (the period of Ming and Qing), it corresponds with Lee Jema's view that medical men in the Song, Yuan, and Ming Dynasties disclosed half of the prescriptions for Tae-eum person by studying these texts more.
