To explain the theory of KIMI which is the theory of therapeutics in oriental medicine, monoamine oxidase(MAO) activities were measured in the brain and liver of mice which were orally administered oriental medicinal herbs which were classified into cold and hot drugs. Rheum palmatum, Anemarrhena asphodeloides, Gardenia jasminoides, Scutellaria baicalensis and Coptis japonica were considered as the cold drugs and Zingiber officinale, Aconitum carmichaeli, Asiasarum sieboldi, Evodia officinalis and Cinnamomum cassia were included in the hot drugs. The effects of cold and hot drugs on in vitro enzyme activities were measured and compared with the in vivo effects. Serotonin is important neurotransmetter involved in the control of body temperature. The MAO plays a central role in the metabolism of many neurotransmetter monoamines including serotonin. MAO is a flavoprotein found exclusively in the mitochondrial outer membrane, occuring in the MAO-A and MAO-B subtypes. MAO-A deaminates serotonin and noradrenaline, whereas MAO-B prefers phenylethylamine and benzylamine as substrates. Coptis japonica and Aconitum carmichaeli elevated the in vivo MAO activities and especialy, in vivo MAO-B activities were significantly increased. In vitro MAO-A activities were increased by hot drugs, whereas the in vitro MAO-B activities were inhibited. Cold drugs inhibited both enzyme activities in vitro.

Crude methanolic(80%) extracts from 109 kinds of traditional herbal drugs were randomly screened for inhibitory effects on 5-hydroxytryptamine(5-HT) uptake in primary cultured rat brainstem neurons. Rat brainstem neurons were cultured from embryonic day 14, and maintained for 7-9 days in vitro. Clomipramine (500 nM), a reference drug, decreased 5-HT uptake to 16% of control values. Of the 109 herbal drugs screened, Citri immaturi Pericarpium(靑皮), Coptidis Rhizoma(黃蓮), Cnidii Rhizoma(土川芎) showed the most potent 5-HT uptake inhibiting activities. These herbal drugs, at the concentration of $10{\;}{\mu}g/ml$, inhibited 5-HT uptake 69, 69, and 57% respectively, when inhibition(%) was expressed as a relative value compared to the 500 nM clomipramine-induced inhibition.

After conversion to their 3,5-dinitrobenzoyl or 3,5-dinitroanilide derivatives, the enantiomers of a number of drugs may be chromatographically separated on various ${\alpha}$-arylalkylamine-derived chiral stationary phases (CSPs). While each CSP used in this study is useful, CSP 1 is best able to resolve the 3,5-dinitroanilide derivative of Ibuprofen while CSP 9 generally gives rather large ${\alpha}$ values for the resolution of 3,5-dinitrobenzoyl derivatives of the enantiomers of ${\beta}$-adrenergic blocking drugs.

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.

In the result of investigating the drugs for replenishing Qi in many herbal books, we could get consistent relation in their immunopharmacologic effects as follows: 1. The effects of drugs for replenishing Qi was shown in the Shen Nong's Herbal, but its classification was natural such as trees and plants, insects and beasts, fruits, vegetables, and we think that trial about classification of drugs for replenishing Qi was accomplished in the ben-cao-jiu-zhen(本草求眞). 2. Main drugs for replenishing Qi was Gingseng Radix, Codonopsis pilosulae Radix, Astragali Radix, Atractylodis macrocephalae Rhizoma, Dioscoreae Rhizoma, Glycyrrhizae Radix. 3. Drugs for replenishing Qi commonly contain polysaccharides as much, and it was thought that they have also immunopharmacolologic effects by means of activating T and B cells, secreting cytokines, making lymphocytes, activating NK cells, increasing abilities of voracity and generating antibodies. 4. Drugs for replenishing Qi mainly replenish lung-Qi and Wei-Qi so that they have also effects of activating T and B cells, secreting cytokines, making lymphocytes, activating NK cells, increasing abilities of voracity and generating antibodies. 5. Drugs for replenishing Qi modulate content of cAMP and inhibit Na(+)-K(+) ATPase, so that they have effects of treating indistinctive pulse from Qi deficiency by means of inhibition delivery of chemical substances, activating lymphocytes. promoting contraction of myocardium.

The efficacy of anticancer drugs depends on a variety of signaling pathways, which can be positively or negatively regulated. In this study, we show that SETDB1 HMTase is down-regulated at the transcriptional level by several anticancer drugs, due to its inherent instability. Using RNA sequence analysis, we identified FosB as being regulated by SETDB1 during anticancer drug therapy. FosB expression was increased by treatment with doxorubicin, taxol and siSETDB1. Moreover, FosB was associated with an increased rate of proliferation. Combinatory transfection of siFosB and siSETDB1 was slightly increased compared to transfection of siFosB. Furthermore, FosB was regulated by multiple kinase pathways. ChIP analysis showed that SETDB1 and H3K9me3 interact with a specific region of the FosB promoter. These results suggest that SETDB1-mediated FosB expression is a common molecular phenomenon, and might be a novel pathway responsible for the increase in cell proliferation that frequently occurs during anticancer drug therapy.

CINC-1 is a member of chemokine family with chemotactic and activating properties to neutrophils. CINC-1 induction in IL-$1{\beta}$-stimulated rat fibroblast NRK-49F cells was quantitated by a sensitive ELISA. CINC-1 production was increased up to 135 ng/ml from basal 2-6 ng/ml by stimulation with IL-$1{\beta}$.Steroidal anti-inflammatory drugs including dexamethasone and prednisolone exhibited potent suppressive effects on IL-$1{\beta}$-induced CINC-1 production. Among 39 kinds of natural triterpenoids tested, acacigenin B exhibited the highest suppressive effects with about $10{\mu}M$ to be 50% of inhibition on the CINC-1 induction. The suppressive potency of acacigenin B on IL-$1{\beta}$induced CINC-1 production was about 10-fold less than that of the steroidal anti-inflammatory drugs.
