This thesis is a study composed of eight chapters from 9. to 16. of the Maek Kyoung(脈經) Vol. VIII. ; the symptom & the pulse of Jaundice(黃疸), Malarial Disease(?疾). Carbuncle(癰腫) Intestines Carbuncle(腸癰), & c. It is as follows : Chapter 9 refers to the symptom, pulse, treatment and prognosis of Jaundice(黃疸) and Malarial Disease(?疾). Chapter 10 refers to the cause, symptom, pulse and treatment of Cardialgia(胸痺), Cardiagra(心痛) and Nephric Accumulation(賁豚). Chapter 11 refers to the symptom, pulse and treatment of Abdominal Fuliness(腹滿), Cold Mounting(寒疝) and Abiding Food(宿食). Chapter 12 refers to the symptom and pulse of Accumulation and Mass of the Five Viscera(五臟積聚). Chapter 13 refers to the cause, pathogenesis, symptom, pulse, treatment and prognosis of Terror and Palpitation due to Fright(驚悸), Hematemesis(吐血), Nasal Hemorrhage(?血), Metrorrhagia(下血) and Extravasated Blood(瘀血). Chapter 14 refers to the cause, pathogenesis, symptom, pulse and treatment of Vomiting(嘔吐), Hiccough(?) and Diarrhea(下利). Chapter 15 refers to the cause, pathogenesis, symptom, pulse and treatment of Atrophy of Lung(肺?), Pulmonary Abscess(肺癰), Lung-distention(咳逆上氣) and Phlegm(痰飮). Chapter 16 refers to the cause, pathogenesis, symptom, pulse. treatment and prognosis of Carbuncle(癰腫), Intestines Carbuncle(腸癰), Wound(金瘡) and Acute Eczema(侵淫瘡). There have been abundant investigations in China. But we couldn't find a clear result yet, and they were written in archaic texts and colloquial Chinese, therefore it is needed to be translated into Korean. And there was only one inaccurate translation with insufficient annotation. So I hope this study will be useful to develope Oriental Medical Diagnostics.

Houttuynia cordata belongs to the Saururacease family and its leaves, stems, and roots have been used as oriental medicines to treat pneumonia, acute or chronic bronchitis, enteritis, and abscesses and to remove extravasated blood. Recently, the antioxidant, anti-inflammation, antibacterial, and anti-proliferation activities and protection abilities of H. cordata against liver and neuron cell damage have been reported. In this study, ethanol extract and its solvent fractions (fractions of hexane, ethyl acetate, butanol, and water residue) were prepared, and their antithrombosis, antidiabetes, antioxidant, and hemolysis activities were evaluated. The ethyl-acetate fraction of H. cordata (EF-HC) showed the highest polyphenol and flavonoids contents among the fractions and exhibited strong antithrombosis and antioxidant activities. The EF-HC at 5 mg/ml showed 2.09-folds of thrombin time, 2.19-folds of prothrombin time, and 1.69-folds of activated partial thromboplastin time compared to the their solvent control and 30.9, 19.9, and 49.6 ㎍/ml of RC₅₀ against DPPH, ABTS, and nitrite radicals, respectively. Furthermore, the EF-HC did not show any hemolytic activity up to 1 mg/ml, whereas the hexane fraction of H. cordata showed 55% hemolysis at 1 mg/ml. This is the first report of the antithrombosis activity of H. cordata. Our results suggest that quercitirin, hyperoside, orientin, and isoquercitrin in EF-HC are related to its antithrombosis and antioxidant activities and that the EF-HC could be developed as a promising antithrombosis agent.
