  • 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.

  • 공업적 목적으로 사용된 후의 아연은 육지와 수계로 유입되며, 토양으로 유입된 후의 아연은 부식되어 수계로 유입된다. 과량의 아연은, 수서생물에 대해 중금속으로서 독성을 가지며 수서 동 ${\cdot}$ 식물의 성장억제를 유발하고, 나아가서는 동물의 기형발생을 초래한다. 본 연구에서는 FETAX (frog embryo teratogenetic assay with Xenopus) 방법에 의해 in vivo에서 과량 아연의 독성을 밝혔다. st. 9 시기에 있는 Xenopus 개구리의 배를 $100{\sim}900\;{\mu}M$ $ZnCl_2$용액에 7일간 노출시켰을 때 100 ${\mu}M$ 아연에서는 81%의 개체가 생존하였고 1000 ${\mu}M$ 에서는 25%가 생존하였다. 그 결과 외형적 이상은 복부팽만과 소화관 형성부전이 일반적으로 나타났고 200 ${\mu}M$ 이상의 아연처리 시 모든 개체에서 이러한 현상이 나타났다. 400 ${\mu}M$ 이상의 농도에서는 모든 개체에서 심장탈색을 보였다. 또한 신체의 탈색과 눈의 수정체 헤르니아, 그리고 느슨한 소화관은 100 ${\mu}M$ 이상의 아연처리에서 매우 빈번히 나타났다. 아연처리 된 유생의 파라핀 조직절편에서는 망막의 광수용기의 파괴, 눈의 초자체방 축소, 심장적혈구수의 감소, 비정상적 간조직, 원신관 세포의 팽윤, 근육형성부전, 그리고 구전정의 유두종 형성 등의 이상을 보였다. 이러한 이장은 미토콘드리아의 파괴 $Ca^{2+}$$Zn^{2+}$의 치환에 의한 세포결합의 저해, 그리고 아연에 의한 적혈구내 leghemoglobin의 형성 등이 원인일 것이다. 과량 아연에 의해 유생의 체장은 감소하였고, 통계분석 결과 체장은 대조군의 체장과 비교했을 때, 300 ${\mu}M$ 아연처리 군부터 매우 유의미하게 체장의 감소가 나타났다. 현재 자연상태에서 양서류의 수적감소와 기형발생이 세계적으로 보고되고 있으며, 본 연구의 결과로 고려했을 때, 과잉 아연은 수계를 오염시켜 양서류의 수적감소를 일으키는 중요한 원인물질로 생각되므로 이의 관리에 관심을 두어야 할 것이다.

  • Traditional herbal medicine is used extensively among the Korean populations, and other Asian countries employ similar therapies as well In recent years, extensive focus was laid on adulteration of the herbal medicine with heavy metals. This may be mainly due to a soil contamination by an environmental pollution. The objective of this study is to identify the contents of various heavy metals in the blood from OhJeokSan-Decoction (OD) treated-rats. For this study, 13 kinds of metals including essential and heavy metals, i.e. Al, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se and Zn were analyzed by a slight modification of EPA methods and the following results are obtained. ; 1. There is no significant difference between the OD-treated groups and control group in liver, kidney, bone, brain, weight, food intake. 2. The amount of each metal analyzed in the liver are as follows; Al ; $0.235{\sim}4.215mg/kg$, As ; $0.103{\sim}0.461mg/kg$, Cd ; $0.005{\sim}0.010mg/kg$, Co ; $0.017{\sim}0.046mg/kg$, Cr ; $0.137{\sim}0.403mg/kg$, Cu ; $1.736{\sim}4.827mg/kg$, Fe ; $54.472{\sim}381.447mg/kg$, Hg ; not detected, Mn ; $1.159{\sim}2.803mg/kg$, Ni ; $0.007{\sim}0.095mg/kg$, Pb ; not detected, Se ; $0.682{\sim}1.887mg/kg$, Zn ; $10.213{\sim}26.119mg/kg$, by groups, respectively. In control and other experimental group, several metal (Co, Cu, Mn, Zn, As, Cr) has a significant difference, but in experimental I and other experimental II, III, IV, V groups, there are no significant difference. 3. The amount of each metal analyzed in the kidney are as follows; Al ; $1.712{\sim}31.230mg/kg$, As ; $0.062{\sim}0.439mg/kg$, Cd ; $0.010{\sim}0.062mg/kg$, Co ; $0.000{\sim}0.101mg/kg$, Cr ; $0.125{\sim}0.636mg/kg$, Cu ; $3.385{\sim}12.502mg/kg$, Fe ; $41.148{\sim}99.709mg/kg$, Hg ; $0.000{\sim}0.270mg/kg$, Mn ; $0.433{\sim}2.301mg/kg$, Ni ; $0.000{\sim}0.221mg/kg$, Pb ; $0.000{\sim}0.584mg/kg$, Se ; $0.540{\sim}1.600mg/kg$, Zn ; $8.775{\sim}17.060mg/kg$, by groups, respectively. The concentration of Cu, Se, Cr, and Hg are variated significantly in control and other experimental group, and Cu, Se, Cd, Cr are variated significantly in experimental I and other experimental II, III, IV, V groups. 4. The amount of each metal analyzed in the bone(tibia and fibula) are as follows; Al ; $9.557{\sim}119.464mg/kg$, As ; $0.139{\sim}12.250mg/kg$, Cd ; $0.000{\sim}0.295mg/kg$, Co ; $0.022{\sim}0.243mg/kg$, Cr ; $0.239{\sim}1.999mg/kg$, Cu ; $0.000{\sim}2.291mg/kg$, Fe ; $240.249{\sim}841.956mg/kg$, Hg ; $0.000{\sim}0.983mg/kg$, Mn ; $0.214{\sim}7.353mg/kg$, Ni ; $5.473{\sim}11.453mg/kg$, Pb ; $0.000{\sim}8.502mg/kg$, Se ; $0.000{\sim}3.005mg/kg$, Zn ; $61.158{\sim}195.038mg/kg$, by groups, respectively. The concentration of Se, Cd are variated significantly in control and other experimental groups, and Se is variated significantly in experimental I and other experimental II, III, IV, V groups. 5. Exceptionally several metal concentration is increased or decreased. but there is no significant harmful difference of metal concentration in the liver, kidney and bone, from the OD-treated-rats compared to those of the control group even if higher dosage($1{\sim}8$ times dosage of person) of OD was administered. Thus, it is expected that the herbal decoction in the traditional herbal medicine would not lay any burden on the body and the heavy metal toxins would not affect our physiological system. However, other kinds of herbal treatment, such as i.v. and i.p. should be considered in terms of metal toxicity in the body since the level of certain metal.
