  • 배 경: COPD 환자에서 흡연은 폐혈관에 직접 작용하여 혈관 수축, 확장 및 혈관세포 증식을 조절하는 매개물질을 분비하여 혈관의 부적절한 개형 및 생리 현상을 초래하여 폐성고혈압을 유발한다. COPD 환자에서는 종종 급성 및 만성 폐혈전증이 일어나고 혈장내 응고전구물질 및 섬유소용해계의 표지자들이 증가되어 있다. 그러나 COPD 환자에서 혈액 응고계 및 섬유소용해계가 우심실 기능 장애에 어떤 기여를 하는지는 잘 알려져 있지 않다. 본 연구에서는 진행된 COPD 환자에서 multidetector CT scan (MDCT)을 이용하여 측정한 우심실 기능에 따른 혈액내 응고계 및 섬유소용해 계의 변화를 알아보고자 하였다. 방 법: GOLD 지침에 따라 COPD로 진단한 26명에서 심장 MDCT scan을 이용하여 우심실 박출계수를 구하였다. 혈액내 thrombin antithrombin (TAT) 및 plasminogen activator inhibitor (PAI)-1은 enzyme linked immunoassay 방법으로 측정하였다. 결 과: COPD 환자의 혈중 TAT는 $10.5{\pm}19.8{\mu}g/L$으로 정상인의 혈중 TAT $3.4{\pm}2.5{\mu}g/L$보다 의미 있게 증가되었으나 (p<0.01) COPD 환자의 혈중 PAI-1는 $29.6{\pm}20.7ng/mL$으로 정상인의 혈중 PAI-1 $25.9{\pm}17.9ng/mL$와 비교하여 의미 있는 변화가 없었다. COPD 환자에서 혈중 TAT는 MDCT scan으로 측정한 우심실 박출계수와 의미 있는 역 상관관계를 보였으나 (r=-0.645, p<0.01) 혈중 PAI-1은 우심실 박출계수와 상관관계를 보이지 않았다 (r=0.022, p=0.92). 결 론: COPD 환자에서 혈중내 응고계는 활성화되어 있으며 혈중 TAT는 우심실 기능 장애의 의미있는 표지자로 사료된다.

  • 목적 : Cyclosporine A(CsA)의 장기적인 치료에서 CsA의 신독성에 의하여 나타나게 되는 만성적인 신조직의 변화는 구심성 소동맥의 수축으로 인한 신혈류의 감소에서 시작되어, 신세뇨관의 위축과 간질조직의 섬유화를 포함하는 비특이적인 간질성 신염과 비교적 특징적이라 할 수 있는 사구체 주위 소동맥의 변화로 나타나게 된다. 본 연구에서는 원발성 및 이차성 신증후군의 CsA치료에서 치료기간 및 원발성 질환에 따른 조직학적인 신독성의 빈도 및 임상적인 신독성과의 관계를 알아보고 최적의 치료기간을 결정하고자 하였다. 방법 : 1986년부터 1997년까지 본원 소아과에서 신장조직검사로 확진된 신증후군 환아 중 스테로이드 저항성, 빈발 재발형 혹은 스테로이드 의존성으로 인하여 CsA로 치료받았던 102례(미세변화신증후군 58례, 국소성분절성 사구체신염 10례, 막성사구체신염 10례, 자반성신염 15례, IgA신병증 9례)를 대상으로 하였다. CsA를 미세변화신 증후군은 1년간 24례, 1.5년간 12례 2년간 22례에서 투여하였고, 국소성 분절성 사구체 경화증은 1년간 2례, 1.5년간 2례, 2년간 6례에서, 막성사구체신염은 1년간 8례, 2년간 2례에서 투여하였다. 자반성신염 과 IgA신병증은 모든 례에서 1년간 사용하였다. 전체 대상 환아에서 치료전과 치료 종료후 1개월 째 신장조직검사를 시행하여 신독성 여부를 조사하였다. 결과 : 전체대상 환아에서 신증후군의 완전관해율은 86%였다(미세변화증후군 96%, 막성사구체신염 90%, 국소성분절성사구체경화증 60%, 자반성신염 80%, IgA 신병증 55%). 스테로이드 반응성의 미세변화신증후군 및 국소성분절성사구체경화증 환아에서 CsA치료후 6개월간의 재발의 빈도는 각각 $0.5{\pm}0.7$회, $0.8{\pm}0.3$회로 치료전 6개월간(각각 $1.8{\pm}0.8$회, $2.0{\pm}0.7$회)에 비하여 의미있게 감소하였다(P<0.0001). 전체 102례의 신증후군 환아중 71례(69.6%)에서 치료전후에 조직학적인 변화를 보이지 않았고 24례(23.5%)에서 간질성 신염을 보였으며 7례(6.8%)에서 혈관변화를 보였다. 미세변화신증후군 환아에서 CsA치료후 관찰된 간질성 신염의 빈도는 1년, 1.5년, 2년 치료군이 각각 16.6%, 33.3%, 27.2%였고, 혈관변화의 빈도는 1년, 1.5년, 2년 치료군이 각각 0%, 16.6%, 9%였다. 임상적인 신독성의 소견은 한례에서도 보이지 않았으며 1년이상 사용군에서 1년이하의 사용군에 비하여 통계적으로 유의하게 조직학적 신독성의 빈도가 증가함을 보였다(P=0.03). 발병연령, 성별, 원인질환에 따른 조직학적인 신독성의 빈도의 의미있는 차이를 보이지 않았다. 결론 : 소아의 원발성 및 이차성 신증후군의 CsA치료에서 치료기간이 의미 있는 만성조직학적 신독성의 위험인자로 나타났으며, 신독성의 위험을 최소화 할 수 있는 적절한 CsA 치료기간은 1년 이하가 바람직 하며, CsA에 의한 신장의 조직학적인 변화는 임상적인 신기능의 감소와 무관하게 나타날 수 있으므로, 조직학적인 신독성을 찾아내는뎨 있어서 신장조직검사의 중요성이 반드시 고려되어야 할 것으로 생각되었다.

  • The intention of this study is to apprehend the con. tents and methods of herb remedies that are commonly conducted when there are health-problem cases of ENT, eyes, teeth and skin. Methods of this study are divided into two stages : 1) For a period of six months from December 1994 to June 1995, some 40 persons who are believed to be well versed with herb remedies have been randomly chosen, and we made a survey on herb remedies by symptoms: and 2) we have endeavored to make their grounds evident through the studies on literatures with the focus on the basic data collected. Their results are as follows: 1) When one feels a pain in ears, such herb remedies are employed as pouring the vapor into ears, which is made by steaming Alaska pollack, or as applying or wiping with the juices of radish or the ginkgo, or' alum. Applying the radish juice is effective for sterilization and fever removal: and applying the ginkgo juice is effective for cleanliness. But, plastering alum, sesame oil or castor oil, or pouring the vapor of Alaska pollack into ears are perhaps effective but do not have any pharmacologic grounds. 2) When one bleeds at the nose, such kinds of herb remedies are applied as stimulating nose or head with cold water, pressing nose or ridge of nose, or filling up nares with mashed mugworts. In addition, they have utilized garlic or leeks. Such methods as stimulating with cold water or just pressing nose and ridge of nose is based on reasonable grounds, i.e. vasoconstriction and vascular compression ; and applying mashed garlic on the sole of foot is good for the circulation of Qui ; and the use of mugworts and leeks is based upon the pharmacological function of hemostasis. 3) When one feels a sore throat such kinds of herb remedies are employed as gargling or rinsing throat with brine, drinking hot gruel or water, or drinking the juice of mugwort, radish, ginger or Chinese quince. Gargling with brine or drinking the juice of mugwort, radish or ginger is based upon the pharmacological function of pain alleviation, fever removal, and detoxication. 4) When a boil is formed in mouth, such herb remedies are applied as spreading honey, brine or alum water, and taking gall nut, Chinese matrimony vine, lotus root, etc, for drugs. Spreading honey, brine or water that is made by infusing gallnut, Chinese matrimony vine, lotus root is based upon such functions as hematosis, astriction, antibacterial, and antiphlogistic, Alum, eggplant and licorice are said to be effective, but their pharmacological effects have no grounds. 5) When one has conjunctivitis such herb remedies are commonly applied as irrigation with brine and dropping breast milk in eyes. Moreover, such other drugs are used as plantain. shepherd's purse, and purslane, etc. The use of brine, breast milk, plantain, shepherd's purse and purslane is based upon such functions as sterilization, antiphlogistic, disinfection and pain relieving. Eriocaulon sieboldianum, bean stem, bean pod and narcissus leaves are said to be effective, but their pharmacological action have no basis. When one has a stye, such herb remedies are applied as extracting eyelashes, stimulating by a massage of middle finger, third finger or big toe, as well as sear ing with a heated bamboo comb that is fine-toothed. Other than these, plantain and nightshade's nuts are used as drugs for it. Extracting eyelashes corresponds with exclusing suppurative node and draining the stye of pus ; and the use of plantain is based upon disinfection: and nightshade's nuts are said to be effective, however, their pharmacological action has no grounds. 6) For a treatment of toothache, such herb remedies are commonly employed as rinsing mouth with brine and holding cold water or gasoline in the mouth ; and as the drugs that are believed to be effective have been Welsh onion, ginger and castor-oil, plant, etc. The use of Welsh onion is based upon pain killing, antiinflammatory actions, and the use of ginger is based upon detoxication and disinfection ; and seeds of castor-oil plants are said to be effective, but they have no pharmacological basis. 7) When one has hives, such herb remedies are commonly applied as rubbing burned straw in affected parts, exposing to its smoke, rubbing with salt, sweeping down with a broom, and spreading and drinking boiled water of trifoliate orange. The use of cassia tora seeds, walnut, aloe and radish is said to be effective. The use of cassia tor a seeds has the functions of intestinal order, anti-paralysis, etc. The use of walnut has resulted in an increase of blood by invigorating spirits ; and the use of aloe is based upon disinfection, antibiotic, anti-salt, antihistamine and detoxication action. But, the effects of radish juice and straw's smoke have no pharmacological grounds. 8) When one gets a boil, such herb remedies are commonly used as applying a plaster, paste of flour mixed with yolk, soy sauce or honey, as well as spreading pounded elm tree. Other remedies that have been said to be effective are ; heating with mugwort, brine, wild rocambole, aloe, onion, squid's bone, etc. The use of mugwort is based upon pain killing, astringent antiinflammatory and tranquility. Wild rocambole is based upon the generation and maintenance functions of cell-joining textures ; elm tree upon antiphlogistic ; aloe upon fever removal and antiphlogistic ; onion on pain killing, fever removal, antiphlogistic and tranquility ; squid's bone on astriction: and brine or vinegar on sterilization. Pine resin and gardenia seed are said to be effective, but they have no pharmacological basis. 9) When one cuts his skin, such herb remedies are commonly employed as spreading mugwort's juice or squid's bone powder, or pressing the wounds. In addition, kalopanax, onion and fine soil are employed. The use of mugwort, kalopanax and squid's bone is based upon such functions as hemostasis, sedation, pain killing, antibacterial ; and fine soil is said to be effective, but it has no pharmacological basis. 10) When one suffers from whitlow, such herb remedies are commonly utilized as heating with boiled soy sauce, spreading soybean paste, or dipping into eggs, etc. Other drugs that have been employed are onion root, brine, eggplant, potato, loach, etc. The use of onion is based upon pain killing and antiphlogistic functions ; and that of brine upon antiphlogistic function. The use of soy sauce or soybean paste, fomentation, eggplant, potato and loach is said to be effective, but it has no pharmacblogic ground. 11) For the treatment of frostbite, such herb remedies are commonly used as dipping the affected part into frozen soybean sack, using boiled water of eggplant stem, garlic caulis, onion, hot pepper, caulis. Onion is based upon antiphlogistic and tranquility actions garlic upon disintection, metabolic exacerbation, tonic and aphrodisiac actions and the use of eggplant and hot pepper is based upon help blood circulation, dissolution and excretion of waste matters in vein. 12) For the treatment of burn, such herb remedies or drugs are commonly used as cleansing with Korean gin, spreading eggs, cleansing with cold water and soap water ; and as brine, cactus, moss, soybean paste, oil, etc. The cleansing with Korean gin, cold water, soap water, brine, vinegar is based upon cleaning and sterilizing functions ; and the use of cucumber is based upon nu. trition provision, and strengthening of resisting power by adjustment of metabolism. The use of potato, cactus, moss, oil and eggs is said to be effective, but their phamacological functions are not clarified. In view of the above results, we can realize that the drugs that have been employed in herb remedies are quite diverse. However, in regard to majority of herb remedies that have been employed by symptoms, the pharmacological functions of their drugs have not been clarified, and they are merely known as effective. Furthermore, they have not been recorded in the literature as yet ; and we confirm that there have been many herb remedies that were executed without the proper knowlege of their effects. It is now our view that the results of this survey may be utilized for consulting data in regard to the use of herb remedies.
