1. Background and Purpose: I intended to understand the medical and pharmacological theory of Taeumin, through a study of the process through which Lee Je-ma discovered the Interior-Overheated-Disease of Taeumin and created the prescriptions for it. 2. Methods: I studied and analized the change in the medical and pharmacological theory, through a historical study on the quotations and prescriptions of "DongYi Soose Bowon". 3. Results: Through a literature study I could find that in the existing Oriental Medicine before Lee Je-ma, the difference of the Liver Febrile Disease of Taeumin and the Stomach Febrile Disease of Soyangin were recognized, and the prescriptions of the two diseases were a little distinguished, but the medical theories of those were not distinguished at all. And I found that the Liver Febrile Disease of Taeumin shows the pain in the eyes and the throat, and drying of the nose due to interior dry and heat, so it is different from the Stomach Febrile Disease of Soyangin that shows irritation of fever, headache, and the trouble in passing feces and urine. Also I could know that Radix Puerariae, Rhizoma Cimicifugae, Rhizoma Ligustici, Radix Angelicae Dahuricae, and Radix et Rhizoma Rhei are Taeumin's medicines because these medicines had been used for Taeumin's syndromes, and that Radix Scutellariae, Radix Platycodi, Semen Raphani, and Fructus Gleditsiae are Tae-Eum-In's medicines because these medicines are known as acting for lung.

This study was investigated to determine the quality control of Oriental medicine from stores dealing in Oriental medicine around Seoul and Daegu. We tested total 120 samples that widely used 15 species in herbal medicine (Lycii Fructus, Platycodi Radix, Angelicae Gigantis Radix and 12 others) being collected from Oriental medicine clinic, pharmacy, Oriental pharmacy, Oriental medical hospital and Oriental drug store. We have estimated Oriental medicine by K.P. (Korean Pharmacopoeia), K.H.P(Korean Herbal Pharmacopoeia) and announcement of KFDA. The items of examination were identification, purity, loss on drying, ash, acid insoluble ash, extract content, essential oil content, assay, heavy metal limit, and pesticides residue(BHC, DDT, Aldrin, Endrin, Dieldrin). As a result, 20 samples in total 120 samples were not satisfied with the standard and 7 species in total 15 species were not satisfied with the standard. Identification test, extract content test and pesticides residue(BHC, DDT, Aldrin, Endrin, Dieldrin) were satisfied with the standard. The result will be the basic data for the quality control of Oriental medicine.

In this paper, we studied what the drug name of Sang-Baik-Pi(桑白皮) Mori Cortex Radicis) is, how to collect it; and how the chief symptoms had changed in the chinese medical references and herbological literatures and formularies. Also we bibliographically analyzed in the herbological way the drugs combinated with Sang-Baik-Pi and their active principles among the prescriptions in the famous medical book; 'Dong-Ui-Bo-Gam', (東醫寶鑑) of our country. Finally, we concluded as foolow. Numerous names of botainical origin were described, but it was not recorded that San-Keun-Baik-Pi(桑根白皮) in old days is different from root bark of Morus sp. in this times. Sang-Baik-Pi has been a common designation since Ming dynasty (AD 1500). Collections of it were independent of seasons, it could effect perfectly over 10 years old. And its cork layer should be removed after collections, it was especially emphacised that root bark on ground was poisonous. The chiefly cured symptoms with Sang-Baik-Pi were constantly not different from the contents of 'Shin-Nong-Bon-Chau-Kyung'(神農本草經) in ancient times, but it has been developed since Ming dynasty. Its uses are widely extended to a surgical and dermatologic desease; rheumatis, beriberi and diabetes in this times. and its efficacies depend upon curing. Prescriptions on Sang-Baik-Pi that were prescribed in 'Dong-Ui-Bo-Gam' are there, 177 drugs combinated with it. Glycyrrhizae Radix is most frequently combinated with Sang-Baik-Pi(frequently 68%). It is proved that Armeniacae Semen, Platycodi Radix etc, in the order take strong effects on anti-tussive, anti-phlogistic, diuretic, anti-pyretic etc. It is expressed 34 times, frequently, that a dose is 3.75g, and it shows that a usual doses is 2-4g. As the above prescriptions are classified, the results is as follows, respiratory tract desease is most frequently in 69 prescriptions, the next gastrointestinal tract 13 times, diuretic 12 times, and antipyretic 11 times. Therefore, Sang-Baik-Pi contains a good remedial value chiefly of the effects upon the respiratory diseases.

Oxidative stress has been implicated in cutaneous damage in various inflammatory skin diseases, including atopic dermatitis (AD). Atoberry is the herb medicine extract which is composed with Spirodelae Herba, Xanthii Fructus, Houttuyniae Herba, Taraxaci Herba, Retinervus Luffae Fructus, Platycodi Radix, and Scutellariae Radix. In this study, we investigated the antioxidant and anti-inflammatory effects of Atoberry in AD-like skin lesion NC/Nga mice. Murine AD-like skin lesions were made by painting Dermatophagoides farinse (Df) extract. Atoberry significantly increased electron donating ability (DPPH), nitrite scavenging (NO) and superoxide dismutase (SOD) activities in dose dependant. Topically applied Atoberry significantly reduced clinical severity score, ear thickness and histological grade in AD-like skin lesion NC/Nga mice. In addition, the serum levels of IgE, NO and prostaglandin E2 were significantly reduced by Atoberry. Futhermore, skin tissue levels of SOD, catalase and glutathione peroxidase (GPx) were significantly reduced by Atoberry. These results demonstrate that topical application of Atoberry may be improve the AD-like skin lesion by antioxidant and anti-inflammatory effects.

A 1, 2-diglyceride-based multi-step colorimetric assay to measure the pancreatic lipase activ-ity was applied for the determination of the kinetic profiles of the lipase inhibition with a slight modification and the validity verification. With this assay method, our study revealed that platy-codin D, one of major constituents of Platycodi Radix, inhibits the pancreatic lipase activity in a competitive type, with the value of $K_1$ being 0.18${\pm}$0.02 mM. In addition, PO has affected the val-ues of $K_{m}$, app/ and $K_{cat}$/$K_{m}$ in a dose-dependent manner. The results shed a meaningful light on how PO mediates lipid metabolism in the intestinal tracts. On the other hand, since the revised assay is sensitive, rapid, and does not affect the accuracy to the kinetic properties, it is applica-ble not only to evaluation of the kinetic properties of the pancreatic lipase, but also to high-throughput screening of pancreatic lipase activity.

This study is carried out to evaluate the genotoxicity of herbs (Angelica decursiva, Polypori umbellate, Astragalus membranaceua, Paeonia iactiflora, Glycyrrhiza uralensis, Cnidium officinale, Rehmannia glutinosa, Cyperus rotundus, Dioscorea batatas and Platycodi Radix) by using the Ames test. The Salmonella typhimurium reversion assay is being performed by using the Sal. typhimurium TA98, TA100, TA102, TA1535 and TA1537 as tester strains. Among 70% of ethanol extracts from 10 herbs, the number of revertant colonies is being increased in Astragalus membranaceua, Cnidium officinale and Dioscorea batatas in a dose-dependent manner, as compared with negative controls of the metabolic activation. In case of dichloromethane and ethyl acetate fraction from 70% of ethanol extracts, the number of revertant colonies is increased in Angelica decursiva, Astragalus membranaceua, Cnidium officinale, Rehmannia glutinosa and Dioscorea batatas in a dose-dependent manner, as compared with negative controls of metabolic activation. Such results indicate that Angelica decursiva, Astragalus membranaceua, Cnidium officinale, Rehmannia glutinosa and Dioscorea batatas all show genotoxic effects when being extracted with the solvent extractions such as 70% of ethanol, dichloromethane and ethyl acetate, and thus, they might be genotoxically- non-safe.

This study was carried out 19 investigate the characteristics of pectinesterase (PE), polygalacturonase (PG), lipoxygenase(LOX) and peroxidase (POD) in hot pepper to know the effect of hot pepper on food quality during food processing and storage. The results were as follows : 1. The optimum pH of PE was pH 7.5 and the activity of PE below pH 5.5 was revealed scarcely, The concentration of NaCl and $CaCl_2$ that showed the highest activity of PE were 0.2M and 0.05M, respectively. 2. The optimum pH of PG was pH 6.0 and the activity of PG in acidity was higher than that in alkalinity. The activity of PG was maximum at 0.3M NaCl and 0.2mM $CaCl_2$. Above the concentration of 0.5M NaCl and 0.5M $CaCl_2$, the activity of PG was lower than that of PG not adding these salts 3. The optimum pH of LOX was pH 7.0 and pH 8.5. 4. The optimum pH of POD was pH 6.0 and the activity of POD was higher in weak acidity and neutrality than in alkalinity. POD activity was slightly decreased by the increase of NaCl and $CaCl_2$ concentration.

The inhibitory effects of Gleditschiae Spina, Cleditschia saponin, two complex prescriptions such as Takrisodokum and Kwaluubangtang, which contain Gleditschiae Spina, and their altered prescriptions on the activity of cyclooxygenase in vitro were investigated. The water extract of Gleditschiae Spina and Gleditschia saponin markedly inhibited the cyclo-oxygenase activity by 59% and 67%, respectively, at a concentration of $1mg/m{\ell}$, on the other hand, Takrisodokum and Kwaluubangtang showed 15% and 7% inhibition, respectively. The extracts with the substraction of Gleditschiae Spina and/or Platycodi Radix inhibited to a much smaller extent than Takrisodokum. However, in case of the extracts with the substraction of Gleditschiae Spina and/or Trichosanthis Semen, only one prescription, which does not contain Trichosanthis Semen, exhibited the same inhibition as Takrisodokum. From above results, Gleditschiae Spina was found to be most important for the effect of Takrisodokum and Kwaluubangtang on their antiinflammatory action. Instead of Gleditschiae Spina, another parts of this plant were added to both complex prescriptions and tested according to above methods, indicating that Gleditschiae Spina is more important than another parts for both prescriptions. When the administered dose of Gleditschiae Spina is increased(twofold and threefold) in both complex prescriptions, the inhibitory effect in Takrisodokum was diminished. however, the effect in Kwaluubangtang was increased.

This study examined the chemopreventive effect of saponins that were isolated from the roots of Platycodon grandiflorum A. DC (Campanulaceae), Changkil saponins (CKS), against the tobacco-specific carcinogen, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), -on lung tumorigenesis in A/J mice. The mice were treated with a single NNK dose (100 mg/kg b.w., i.p.). CKS (0.5, 1, 4 mg/kg body wt.) was administered orally daily for 3 days/week beginning 1 day after the NNK treatment and was maintained throughout the experiment. The administration of CKS suppressed the NNK-induced increase in the level of proliferating cell nuclear antigen, which are a marker of cell proliferation, in the lungs of the mice 4 weeks after the NNK injection. Twenty-five weeks after the NNK treatment, the mice were sacrificed and the number of surface lung tumors was measured. CKS significantly reduced the number of lung tumors induced by NNK in a dose dependent manner. These results suggest that CKS suppresses the development of lung tumors and has a chemopreventive effect against NNK-induced mouse lung tumorigenesis.
