In the result of investigating traditional chinese medical literatures to understand definite immunopharmacologic effects of drugs for clearing away heat and detoxicating such as Ampelopsis Radix, Rhapontici Radix, Cremastrae Appendiculatae Tuber, Rhaseoli Radiati Semen, Potentillae Discolohs Herba, Potentillae Chinensis Herba, Chrysanthemi Indici Flos, Lomcerae Caulis, we could reach conclusions as follows: 1. Rhapontici Radix, Chrysanthemi Indici Flos can increase voracity of leukocytes, macrophages and increase to produce IL-2 by splenocytes. 2. Potentillae Chinensis Herba, Chrysanthemi Indici Flos, Lonicerae Caulis can inhibit activities of B lymphocytes and have anti-inflammatory effects. 3. Drugs for clearing away heat and detoxicating almost have antibiotic, anti-inflammatory effects, and so can be applied to many inflammatory immune diseases. 4. Drugs for clearing away heat and detoxicating also have antifebrile, diuretic, detoxicating effects. Above results indicates that Drugs for clearing away heat and detoxicating have immunosuppressive effect, so that can be applied to many inflammatory immune diseases.

If we eat long time foods that don't suit our constitution, health is broken and we take a disease. Therefore, care of foods and taking medicine by constitutional notion have a object that is normal control of constitution. It is attained when we maintain an adequate balance of Jang and Bu(臟腑) organs functional deflection. Theory of SaSang constitution by Lee-Jae Ma provides us a proper base of theory. But, later foods and drugs classified by constitution, that is suggestied by many scholars, is some different. Therefore, it is doubtful whether choice of foods and drugs suitable to constitution is right. If we use foods and drugs suitable to constitution exactly, we can decrease a side effect arisen from unsuitableness. On this, I study by literatures in order to provide foundational data. Lee-Jae Ma classified four species constitution, I compared twelve literatures by constitution, classified profit and harmful foods, and arranged and classify drugs that literature writer suggests in common. On base of this study, I suggest that foods and drugs classified by constitution is as follows. 1. Lee-Jae Ma made SaSang constitution medicine, but didn't suggestied use of foods, therefore, commoness of foods constitutional classification must be arranged. 2. Also commoness of drugs constitutional classification must be arranged. 3. Other literatures must be compared and analyzed except those of this study, because I didn't analyze many SaSang literatures.

Effects on the bacteria gwoth of 96 kinds of crude drugs described in "Pen-Tsao-Kang-Mu" was investigated. Galla Rhois, Moutan Cortex Radicis, Aconiti Tuber, Euphorbiae Radix and PAeoniae Radix showed the antibacterial activity but Cnidii Rhizoma, Coicis Semen, Angelicae gigantis Radix, Asparagi Radix and Liriopes Tuber show the gwoth promoting action of all bacteria used in this experience. It can be seen that 10 kinds of crude drugs classified as poisonous plants inhibited the growth or had no effect by never promoted. 32 kinds of crude drugs as drugs acting on the gastrointestinal system showed antibacterial activity on E. coli $O_{55}$ and E. coli $O_{111}$. 18 kinds on inflammation showed antibacterial activity on Staphylococcus aureus and Sarcina lutea.

We investigated effects of methanol extract of Aloe vera on anticancer drugs(cisplatin, mitomycin C, 5-fluorouracil)-induced growth inhibition in p388, L1210, HCT-15, SK-HepG-1 as cancer cell lines and mouse splenocytes as a normal cell by MTT assay, respectively. We also examined the effects of aloe extract and mitomycin C on the mitogen(Con, A, LPS)-induced splenocyte proliferation. Aloe extract(0.25 mg/m , 1.25 mg/m , 2.5 mg/m , 5.0 mg/m ) showed dose-dependently selective cytotoxicity against the cancer cell lines. In contrast, Aloe extract increased the growth and proliferation of the normal mouse splenocytes. The combination of aloe extract with anticancer drugs showed an additive effect for the cytotoxicity against cancer cell lines. However, that combination reduced clealy the anticancer drugs-induced toxicity against the normal mouse splenocytes.

Such carboxyl drugs as mefenamic acid, alclofenac, ketoprofen, cicloxilic acid and tolfenainic acid in rat plasma were determined by the gas chromatography flame photometric detector (GC-FPD). After methylthiomethyl (MTM) esterification with MTM-chloride in 1, 8-diazabicyclo [5.4.0] undec-7-ene (DBU) catalyst, determination of these drugs by this method was tried and compared with that by the GC-flame ionization detector (FID) method in respect to sensitivity and effect of inteferences. The results showed it was possible to analyze with accuracy by this method because of specificity of the FPD, although these drugs were not separated from interferences in plasma on GC column. The GC-FPD method was more sensitive than GC-FID method and the minimum detectable amount of monocarboxylic drugs on 3%, QF-1 column was about 15fmol/injection.

The targeting of DNA methylation in cancer using DNA hypomethylating drugs has been well known to sensitize cancer cells to chemotherapy and immunotherapy by affecting multiple pathways. Herein, we investigated the combinational effects of DNA hypomethylating drugs and ionizing radiation (IR) in human sarcoma cell lines both in vitro and in vivo. Clonogenic assays were performed to determine the radiosensitizing properties of two DNA hypomethylating drugs on sarcoma cell lines we tested in this study with multiple doses of IR. We analyzed the effects of 5-aza-dC or SGI-110, as DNA hypomethylating drugs, in combination with IR in vitro on the proliferation, apoptosis, caspase-3/7 activity, migration/invasion, and Western blotting using apoptosis- or autophagy-related factors. To confirm the combined effect of DNA hypomethylating drugs and IR in our in vitro experiment, we generated the sarcoma cells in nude mouse xenograft models. Here, we found that the combination of DNA hypomethylating drugs and IR improved anticancer effects by inhibiting cell proliferation and by promoting synergistic cell death that is associated with both apoptosis and autophagy in vitro and in vivo. Our data demonstrated that the combination effects of DNA hypomethylating drugs with radiation exhibited greater cellular effects than the use of a single agent treatment, thus suggesting that the combination of DNA hypomethylating drugs and radiation may become a new radiotherapy to improve therapeutic efficacy for cancer treatment.

사람 중성구내의 azurophil granule 내에 존재하는 serine protease인 cathepsin G는 정상 반응에서는 항 박테리아 작용을 나타내는데 관여하지만, 이들의 효소활성이 비정상적으로 증가되었을 때는 오히려 인체 정상 조직을 파괴함으로써 rheumatoid arthritis를 비롯한 여러가지 염증성 질환을 야기시킨다고 알려져 있다. 항염증제로 작용하는데 있어서 prostaglandin 합성을 억제하는 작용 이외에 다른 작용 기전이 있는가 하는것은 대단히 흥미있는 연구 과제이었으므로 neutral protease 중의 하나인 cathepsin G와 이 염증반응에 직접적으로 관여하는지 알아보기 위하여 본 연구에서는 두 단계의 크로마토그라피를 거쳐 순수한 cathepsin G를 분리하고, 여러가지 비스테로이드성 항염증제를 이용하여 cathepsin G에 대한 억제 정도를 관찰하였다. 이중 sulindac, salicylate, phenylbutazone, oxyphenbutazone 그리고 salicyluric acid가 각각 4.3mM, 14.3mM, 6.5mM, 11mM, 15mM의 $IC_{50}$로써 cathepsin G의 활성도를 억제하였다. 따라서 NSAIDs의 항염증 작용 기전은 기존에 알려지고 있는 cyclooxygenase 억제에 따른 prostaglanndin 합성, 분비 억제 기전이외에 rheumatoid arthritis 부위에 직접적 원인으로 작용할 가능성이 있는 cathepsin G를 억제 함으로써 조직 파괴를 막는 역할을 하고 있을 가능성이 있는 것으로 사료된다.

The screening of 150 Chinese drugs which are most frequently prescribed in Korean traditional medicine showed that at least 30% of the drugs affected barbiturate-induced hypnosis. This effect was mainly attributable to the alteration of drug metabolism. Phytochemical works resulted in the isolation of furanocoumarins, lignans, sesquiterpenes and saponins as drug metabolism modifiers. The structure-activity relationship is discussed.

The unstirred water layer (UWL), which has been known to exist in the boundary of the intestinal lumen and intestinal wall, often behaves as an absorption barrier especially for lipophilic drugs. The intestinal absorption of drugs is often characterized using Caco-2 cell monolayers grown on Transwell polycarbonate membranes. The permeability $(P_{app})$ of drugs across the cell monolayer might be influenced by the agitation of the donor compartment, since the width of UWL on the surface of the cell monolayer would be reduced by the agitation. In this study, the effect of agitation of the donor compartment with 60 rpm on the permeability was measured for 12 drugs with a wide range of lipophilicity and permeability. The $P_{app}$ of mannitol, tributylmethyl ammonium, cimetidine, ranitidine, hydrocortisone, benzylpenicillin and loxoprofen was not influenced by the agitation, while the $P_{app}$ of theophylline, propranolol, YH439, phenylpropanolamine and testosterone was increased by the agitation. There was a significant correlation between the increase of $P_{app}$ by agitation and the lipophilicity for the compounds having $P_{app}>2{\times}10^{-5}$ cm/sec. No correlation was observed for the difference in $P_{app}$ by agitation and the molecular weight, or lipophilicity of the drugs. Therefore, the agitation rate of the donor compartment in the Caco-2 cell monolayer study should be carefully controlled in order to estimate $P_{app}$ reproducibly especially for lipophilic drugs.

Natamycin is a widely used antifungal antibiotic. For natamycin biosynthesis, the gene pimE encodes cholesterol oxidase, which acts as a signalling protein. To confirm the positive effect of the gene pimE on natamycin biosynthesis, an additional copy of the gene pimE was inserted into the genome of Streptomyces gilvosporeus 712 under the control of the ermE* promoter (p_ermE*) using intergeneric conjugation. Overexpression of the target protein engendered 72% and 81% increases in the natamycin production and cell productivity, respectively, compared with the control strain. Further improvement in the antibiotic production was achieved in a 1 L fermenter to 7.0 g/l, which was a 153% improvement after 120 h cultivation. Exconjugants highly expressing pimE and pimM were constructed to investigate the effects of both genes on the increase of natamycin production. However, the co-effect of pimE and pimM did not enhance the antibiotic production obviously, compared with the exconjugants highly expressing pimE only. These results suggest not only a new application of cholesterol oxidase but also a useful strategy to genetically engineer natamycin production.
