  • Blood-Letting Therapy is a rational and ecological medical treatment by which we can heal most of the diseases by removing the static blood which precipitates in the blood vessel and blocks the flowing of blood. And the static blood is the generic term for the injurious, bad, dead and precipitated blood which is blocked the capillary vessel. The Yellow Emperor's Canon of Internal Medicine says that "the patient is treated with drugs internally and stone acupuncture externally. "In the old texts, the blood-letting therapy is mentioned as blood-letting, network vessel pricking, bloodletting, pricking, and arousing pulses etc and it is noted down as the method of network vessel pricking in 'On the Application of Needles' of Spiritual Pivot. Nine-pricking therapy, twelve-pricking therapy and five-pricking therapy are recorded in the methods of network vessel pricking and among them, the method of squeezing blood after pricking the affected part is explained as the network vessel pricking. There are four methods of network vessel pricking, pricking, picking, cluster needling and scatter-pricking and they are fluidly applied to the various symptoms of diseases. In 'On Discriminative Treating for Patients of Different Regions' in Elementary Questions, Ki-baek emphasizes "most of the local people, there are black in skin and loose in striate, and their diseases are mostly of carbuncle kind. It is suitable to treat the disease with stone therapy to prick with stone, so the stone therapy is transmitted from the east. "And in 'On the Corresponding Relation Between the Eum and Yang of Man and All Things' in Elementary Questions, when the Emperor asked Ki-Back, he answered "sthenia means the sthenia of evil, and deficiency means the deficiency of healthy energy. When the blood is sthenic, the evil should be discharged by pricking when out letting the blood; deficiency of vital energy is the asthenia of channels and network vessels, so the energy should drain from the channel which is not deficient, to replenish. "And in this case we can use the methods of 'Breaking out the static bloods', 'driving out the static bloods', blood-letting'. With this we can infer that the blood-letting therapy is made use of the important medical treatments from the ancient times. Especially in referring to the principles of treatment in The Yellow Emperor's Canon of Internal Medicine, it mostly alluded to acupuncture therapies and only eleven times to medicinal treatments. This is to verify that the blood-letting therapy formed the foundation of the medical art. In Dong's Therapy of Acupuncture-Moxibustion and Bloodletting, Dong Kyeong-Chang gave emphasis on the points that there must be extravasated bloods without exception in the serious illnesses which is old, unnatural, accompanying acute pains and so we can revive our body‘s sprit by circulating 'gi' and static blood piled up in the network vessel, regulating the weakness and strength, and controling the disharmony of the internal organs. The blood-letting therapy has effect on the orifice in emergency, such as fore draining, freeing network vessels, harmonizing gi and blood, relieving pain, dispersing swelling and concretion, sedation, resolving toxin as well as strengthening the heart, relieving itching. So it has distinguished effect on all kinds of medical treatment to the modern people. But by the change of social customs and the confucianism of confucius - it is widely spread on the period of North and South Dynasties, 'Wi' and 'Jin' in china and the period of the Three States in korea - The blood-letting therapy which was regarded as the most important medicinal treatment withered rapidly. And Confucius accentuated the importance of our body and all its members, loyalty and filial piety and banned any damage of our body under no circumstances. As a result of it, the therapy of blood-letting had a rapid decrease and barely kept itself in existence in both countries. What is worse, at the period of Japanese colonial rule of korea and our nation's founding of early stage, it has been withered by the high-handed policy to change Oriental Medicine into modern medical science. So the therapy of blood-letting barely kept itself in existence in some Buddhist temples. Another case, it has handed down as a old-fashioned quick fix in folk remedies. But all kinds of the contamination of heavy metals and the misuses of antibiotics are widely spread nowadays, which increased diseases of adult people and incurable diseases as modern society unavoidably made its way into a highly industrial society. To make us more miserable, the western medical science - the antibiotics and surgical operation medical science - already reveals itself into a limit. The necessity of a new medical science which can give a security to the patients who are suffering from the diseases of adult people and the incurable diseases is especially come into the force nowadays. In view of the results after bibliographically studying on the blood-letting Therapy in Elementary Questions of the Yellow Emperor's Canon of Internal Medicine, the blood-letting therapy has acted for the important Oriental medicinal science and has been clarified the prominent effects on the diseases of adult people and the incurable diseases. So it is regarded as an appropriate thing that we lay out a determined theory of the blood-letting therapy and of course prevent the unwanted side effects from inappropriate medicinal treatments, and make full use of clinic by elevating the curative value and that we win back our self-respect of medical treatment which is dominated from the western medical science and ultimately contribute to national medical welfare.

  • An analysis has been made of two hundred seven patients who were treated at the department of Radiation Oncology of Korea University Hospital for lung cancer from January 1981 through December 1986. There were 137 patients of nonsmall cell carcinoma (137/207, 66%), 26 patients of small cell carcinoma (26/207, 12.5%) and 44 patients of unproven histology. By aims of treatment, there were 104 patients (104/207, 50%) treated for cure, 89 patients (89/207, 42.9%) for palliation and 14 patients treated postoperatively. In 22 out of 207 patients, chemotherapy was done with radiotherapy, 12 of which were patients with small cell carcinoma. Stage II patients were 49 (49/207, 23.6%), stage III patients were 157 (157/207, 75.8%) and one patient had an occult cancer The tumor was initial Iy measured by CAT scan and chest X-rays in the 165 (165/207, 79.7%) patients, among which 117 patients had tumor diameter more than 5cm and 48 patients less than 5cm. Radiation therapy was given with Cobalt 60 teletherapy unit and the treatment volume encompassed primary tumor and the mediastinum. For curative aim, daily tumor dose of 180 cGy was given up to the range of 5,400~6,120cGy/30~34F/6~7 week period and for palliative aim, daily tumor dose of 300 cGy was given up to the range of 3,600~4,500 cGy/12~15F/2~3 week period. Postoperatively, mediastinum was treated for total dose of 5,040 cGy/28F/5.5 week period. 123 patients (123/207, 59%) were followed up after completion of radiotherapy for 14 months to 7 years. Local tumor response to the irradiation was measured by chest X-ray taken at one month follow up and was evaluated for response rate, if they were regressed more than 50% or less than 50% of the initial tumor size. The treatment results were as follows; 1. The median survival time was 8.5 months and survival rates for 1 year, 2 year and 5 year was 25%, 3.5% and 1% of nonsmall cell lung ca of 74 evaluable patients. 2. More than 50% of local tumor response rate was obtained in about half of overall cases; 90.5% for small cell ca, 50% for squamous cell ca, 25% for adenoca and 57% for large cell ca. 3. Response rate more than 50% was seen in the 50% of the patient group with tumor diameter more than 5cm and in the 55% of those with tumor diameter less than 5cm. 4. By total raidation dose given, patient group which was given 5,400~6,120 cGy equivalent dose or higher showed tumor response rate more than 50% in 53% of the patients, whereas the group with dose less than 5,400cGy equivalent, in 25% of the patients. 5. Survival rate for 6 month, 1 year and 2 year was compared between the group of local tumor response rate more than 50% vs. group with response rate less than 50%; 74% vs. 43%, 33% vs, 23%, 10% vs. 1%, respectively. 6. Local failure was seen in 21%(44/207) of the patients, which occured mostly within 15 months after completion of radiation therapy. Distant metastases were seen in 49.7%(103/207) of the patients, of which 43 cases were found before initiation of radiotherapy. The most common metastatic sites were bone and brain. In this sutdy, 1 year,2 year and S year survival rates were somewhat poor compared to the other studies. It mainly seems to be due to the poor general status of the patients and the far-advanced stage of the disease. In nonsmall cell cancer patients who had limited local disease and had small primary tumor size, we observed better local response. In addition, dose higher than 6,000 cGy group showed better tumor control than lower dose group. Survival rate was better for the local control group. For imporvement of local control of the lung cancer and hence, the survival of the patients with lung cancer, proper radical radiotherapy with high dose for localized disease is needed. New modality of treatment such as high LET beam in radiation therapy or drugs for the advanced disease as well as early diagnosis is also needed.

  • 최근 들어 먹거리와 건강에 대한 사람들의 관심이 점점 높아지면서 이에 관한 정보 또한 중요시 되고 있다. 우리나라 전체 사회가 고령화 사회로 접어들면서 환경의 악화로부터 오는 질병과 생활 습관병의 증가를 자기 자신의 문제로 받아들이는 사람들이 늘고 있기 때문이다. 의료 분야는 치료 중심에서 예방 의학으로 관심이 높아지고 있지만 예방약이라고 할 수 있는 약품은 매우 적다. 암, 동맥경화, 당뇨병 같은 성인병을 예방하려면 약에 의한 예방이 아닌 먹거리에 의한 예방을 적극적으로 도입시킬 필요가 있다. 해양은 육상과는 다른 특이한 생태계를 이루는 환경 때문에 적자생존의 경쟁 속에서 살아남기 위하여 특히 물리적 방어 능력이 부족한 해양생물의 2차 대사산물은 육상생물의 그것과는 상이한 화학적 특성을 가진다. 이러한 다양한 2차 대사산물은 화학적 방어 수단의 일환으로 생성되는 것으로 알려져 있는데 이들 물질이 인체나 다른 포유동물에 투여되면 강력한 생리활성을 발현하는 경우가 많다. 이러한 이유들 때문에 해양생물로부터 새로운 생리활성 선도물질을 개발하여 인류의 건강 보전에 이용하고자 하는 연구가 최근 각광받고 있다. 해조류, 어패류 및 수산가공부산물(폐기물)에서 기능성을 나타내는 단백질 가수분해물 및 펩티드의 제조 방법 및 항균, 항산화, 심장보호(항고혈압, 항동맥경화 및 항응고), 면역조절, 항당뇨, 식욕억제 및 신경보호 활성과 같은 여러가지 생리 기능성에 대하여 살펴보았다. 무엇보다도 해양단백질 가수분해물 및 펩티드가 다양한 생리활성을 갖고 있어 건강식품 및 식의약 산업에서 응용이 가능하고 원료인 해조류 및 수산가공부산물이 대부분 미이용자원이므로 관련기업에서의 상품화 개발이 이루어질 것으로 기대된다. 최근에 소비자나 환자들도 의약품에 대한 바람직하지 않은 부작용을 의식하고 있고 화학적으로 합성된 의약품을 기피하는 경향이 있고 자연식품이나 천연 생리기능성 물질에 대한 욕구로 자가치료에 대한 사고방식이 높아지고 있어 의약품 보다는 효능이 다소 낮을지라도 어떤 질병의 예방이나 치료를 위해 특수한 생리기능성 물질의 섭취는 더욱 더 인기를 끌게 될 것으로 기대된다. 그러나 단백질 가수분해물이나 펩티드가 신체에서 나타내는 상태와 생리기능성 효과 사이에 상호관계를 충분히 밝혀져야 하며 이들을 이용한 제품의 보다 확실한 생리기능성의 작용 메커니즘과 임상에서의 효능의 확인이 이루어져야 하며 마켓팅을 위해서는 무엇보다도 공인기관인 식약처 또는 FDA에 인증을 받아야 할 것이다.

  • 연구배경 : 내독소 유도성 급성 폐손상(acute lung injury : ALI)은 비교적 임상에서 흔히 접하는 호흡기질환으로서, 조기에 적절한 치료가 이루어지지 않을 경우 예후가 좋지 않은 것으로 알려져 있다. 하지만 최근 몇 가지 보조치료약제가 임상에서 사용되고 있기는 하지만, 아직 ALI를 효과적으로 치료할 수 있는 약제는 개발되어 있지 않은 실정이다. 이에 본 연구지들은 최근 ALI의 새로운 보조치료약제로서의 가능성이 대두 pentoxifylline (PF) 및 ONO-5046(specific neutrophil elastase inhibitor)이 백서의 내독소 유도성 ALI와 관련된 염증반응에 대해 어떤 효과를 나타내는지 알아보고자 하였다. 방법 : 내독소 유도성 ALI의 생체외(in vitro) 모델을 확립하기 위해 백서의 폐포대식세포 및 말초혈액 호중구를 다양한 비율(1:0, 5:1, 1:1, 1:5, 0:1)로 혼합하여 내독소 자극 하에서 백서의 폐포상피세포주(L2 cells) 혹은 혈관내피세포주(IP2-E4 cells)와 함께 혼합 배양하였다. 모든 실험은 5군(대조군, LPS군, LPS+PF군, LPS+ONO군, LPS+PF+ONO군)으로 나누어 비교하였는데, 우선 다양한 비율로 혼합된 백서 폐포대식세포 및 말초혈액 호중구의 배양상층액으로부터 내독소 유도성 과산화음이온 생성능을 측정하고, 이들 염증세포들이 각 폐조직세포에 미치는 세포독성능을 측정하였다. 아울러 백서의 폐포대식세포로부터 내독소 유도성 TNF-$\alpha$, MCP-1, IL-6, IL-$1{\beta}$, IL-10 분비 및 TNF-$\alpha$ iNOS, MCP-1 mRNA 발현을 관찰하였다. 결과 : (1) 세포혼합비가 1:5일 때 LPS+PF+ONO군을 제외하고는 세포혼합비에 상관없이 LPS+PF군, LPS+ONO군 및 LPS+PF+ONO군 모두에서 각 세포혼합비의 LPS군에 비해 백서 폐포대식세포와 말초혈액 호중구로부터 내독소 유도성 과산화 음이온 생성능이 억제되는 경향을 보였다. (2) 백서 혈관내피세포(IP2-E4 cells)에 대한 염증세포들의 내독소 유도성 세포독성능은 세포혼합비에 상관없이 LPS+PF군, LPS+ONO군 및 LPS+PF+ONO군 모두에서 각 세포혼합비의 LPS군에 비해 감소하는 경향올 보였다. 하지만 백서 폐포상피세포(L2 cells)에 대한 염증세포들의 내독소 유도성 세포독성능은 세포혼합비 및 각 실험군에 따라 다양한 양상을 보였다. (3) LPS+PF군 및 LPS+PF+ONO군 포두에서 백서 LPS군에 비해 TNF-$\alpha$ 분비가 LPSrns에 비해 통계적으로 유의하게 감소되었으며, MCP-1 및 IL-10 분비도 LPS군에 비해 다소 감소 하는 경향을 보였다. 반면에 LPS+ONO군은 LPS군과 비교하여 백서 폐포대식세포로부터 내독소 유도성 cytokines 분비에 별 차이가 없었다. LPS+PF군, LPS+ONO군 및 LPS+PF+ONO군 모두에서 백서 폐포대식세포로부터 내독소 유도성 IL-$1{\beta}$ 및 IL-6 분비는 LPS군에 비해 오히려 증가하는 경향을 보였다. (4) LPS+PF군, LPS+ONO군 및 LPS+PF+ONO군 모두에서 백서 폐포대식셰포로부터 내독소 유도성 TNF-$\alpha$ 및 MCP-l mRNA 발현이 억제되는 경향을 보였으나, iNOS mRNA 발현은 오히려 증가하는 경향을 보였다. pentoxifylline은 백서의 염증세포들로부터 내독소 유도성 과산화 음이온 생성을 억제하였고 폐포대식세포로부터 TNF-$\alpha$ 및 MCP-1 mRNA 발현과 억제하여 폐조직세포 손상을 감소시켰으며 ONO-5046은 과산화 음이온 생성억제 및 TNF-$\alpha$ MCP-1 mRNA 발현억제, MCP-1의 분비를 억제하였을 뿐 아니라 항염증 매개물질인 IL-10 분비를 증가시킴으로써 폐조직세포의 손상을 방지할 수 있음을 확인하였다. pentoxifylline과 ONO-5046의 병용투여시에도 과산화 음이온 생성 및 일부 염증성 물즐의 mRNA의 발현 및 분비를 억제함으로써 폐조직세포의 손상을 방지함을 확인할 수 있었다. 결론 : 이상의 결과들로 보아 PF 및 ONO-5046은 내독소 유도성 ALI의 염증반응을 완화시키는 역할을 하는 것으로 추측되며, 향후 이 약제들은 ALI의 새로운 보조 치료제로 사용하기 위해서는 추가 연구가 필요할 것으로 생각되는 바이다.
