The authors investigated drug interaction of ibuprofen and prednisolone in antiinflammatory and antipyretic activities. We have found significant differences of the antiinflammatory and antipyretic activities between single and concurrent administration of ibuprofen and prednisolone, using Sprague-Dawley Strain rats, carrageenin as a phlogistic agent and brewer's yeast as a fever inducing agent. 1) Ibuprofen(20mg/kg) was administered to the rats orally and resulted in significant reduction of (31.70 %) the swelling of rat paw induced by carrageenin, 2) prednisolone (9mg/kg) showed significant reduction of (45.76%) the swelling, 3) concurrent administration of ibuprofen (20mg/kg) and prednisolone (9mg/kg) also reduced (57.40%) the swelling. In ibuprofen (125mg/kg) administration, the inhibition rate of edema was 39.32% and in prednisolone (1mg/kg) administration, the rate was 39.04%. In concurrent administration of ibuprofen (125mg/kg) and prednisolone (1mg/kg), the inhibition rate of edema was 63.09%. Concurrent administration of ibuprofen and prednisolone showed more anti-inflammatory effects than single administration of ibuprofen and prednisolone respectively. Prednisolone itself did not show antipyretic effect, but concurrent administration of ibuprofen and prednisolone showed more antipyretic effects than ibuprofen single administratron.

Polysaccharides were isolated with alkaline extraction method from twelve pharmaceutical plants, which have been used against the various tumors in the oriental herb medicine, and examined for their antitumor activities. When the polysaccharides were administered i. p. at the dose of 10mg/kg/day for ten consecutive days to the male ICR mice, which had been implanted with $1{\times}10^{6}$ cells of sarcoma 180 twentyfour hours before the first injection of polysaccharides, those from Forsythia Corea, Curcuma, Zedoaria, Albizzia Julibrissin, Prunuts Persica, Foeniculum Vlugare and Daphne Pseudogenkwa showed inhibition ratios of 88.0%, 61.1%m 73.0%, 72.8% 55.1% and 71.7%. The significant prolongation of life span was observed only in the case of Forsythia Corea (18.1%). Other six polysaccharide fractions from Olibanum, Lonicera Japonica, Rheum Coreanum, Scirpus Maritimus, Gleditchia Officinalis and Brassica Juncea showed negligible inhibition ratios.

The solid-phase synthesis of new series of 1,6,8-trisubstituted tetrahydro-2H-pyrazino[1,2-a]pyrimidine-4,7-diones as bicyclic $\beta$-turn mimetics is described. Their NF-kB inhibition activities were tested and the effect of substituents on bicyclic ring was investigated. Among the prepared compounds, the fluorobenzyl and methoxybenzyl group substituted compounds 26 and 27 at C-1 and C-8 position showed more inhibitory activities than the others. Tested at a concentration of 10 uM, these two compounds showed a 60% inhibition against the target NF kB 549.

11-Keto-derivatives of pomolic acid, $\beta$-boswellic acid and presenegenin were compared with those of oleanolic acid, hederagenin and glycyrrhetinic acid in respects of inhibitions on corticoid-5.betha.-reductase and anti-inflammatory activities. Hyddrophilicity of ring A and hydrophobicity of rings C/D enhanced the inhibition on the enzyme. However, the former induced edema and the latter caused to exhibit anti-inflammatory activity.

The effect of imperatorin on hepatic microsomal mixed function oxidases (MF0) was investigated. On acute treatment, imperatorin (30 mg/kg, i.p) caused a significant reduction in activities of hepatic aminopyrine N-demethylase, hexobarbital hydroxylase and aniline hydroxylase as well as cytochrome p0450 content in rats and mice. Kinetic studies on rat liver enzymes revealed that imperatorin appeared to be a competitive inhibitor of aminopyrine N-demethylase (Ki,0.007 mM), whereas a non-competitive inhibitor of hexobarbital hydroxylase (Ki, 0.0148 mM). Imperatorin also inhibited non-competitively aniline metabolism (Ki 0.2 mM). Imperatorin binds to phenobarbital-induced cytochrome p-450 to give a typical type 1 binding sepctrum (max. 388nm, min 422 nm). Multiple administrations of imperatorin (30 mg/kg. i. p. daily for 7 days) to mice shortended markedly the duration of hexobarbital narcosis and increased activities of hepatic aminopyrine N-demethylase and hexobarbital hydroxylase and the level of cytochrome p-450 where as aniline hydroxylase activity was unaffected.

Antimicrobial activities against Streptococcus mutans, Candida albicans, Escherichia coli, Staphylococcus epidermidis, Staphylococcus aureus were assayed through the hot water extracts and the ethanol extracts from Chungyulsodokeum and its composition oriental medicines. The stains were incubated on culture medium and activated. We observed the size of inhibition zone on the strains that is incubated in strilized filter paper disc with various concentration extracts of Chungyulsodokeum and its composition 1. The extracts of Chungyulsodokeum, Coptidis Rhizoma, Paeoniae Radix, Glycyrrhizae Radix, Gardeniae Fructus showed antimicrobial activities against Staphylococcus aureus. 2. The extracts of Chungyulsodokeum, Coptidis Rhizoma, Paeoniae Radix, Forsythiae Fructus Ghycyrrhizae Radix, showed antimiaobial activities against Staphylococcus epidermidis. 3. The extracts of Chungyulsodokeum, Coptidis Rhizoma, Paeoniae Radix, Glycyrrhizae Radix, showed antimicrobial activities against Streptococcus mutans. 4. The extract of Coptidis Rhizoma showed antimicrobial activities against Candida albicans. 5. None of the extracts showed antimicrobial activities against Escherichia coli. We observed antimicrobial activities of Chungyulsodokeum and its composition against Streptococcus mutans, Staphylococcus epidermidis, Staphylococcus aureus.

Several studies of terbenzimidazoles and bibenzimidazoles suggested that benzimidazoles, especially 5-nitro-2-(para-methoxyphenyl)benzimidazole. possess topoisomerase I inhibition activities. In order to find out the structure activity relationship of 5-nitro-2-phenyl-benzimidazoles. eight derivatives that are substituted at the para position of 2-phenyl moiety were selected, synthesized ＆ evaluated considering their electronic or lipophilic parameters.

Abstract The protective effects of physostigmine against the toxicity of parathion (diethyl-4-nitrophenyl phosphorothionate) were examined in male Sprague-Dawley rats. Physostigmine (100 or 1,000 ㎎/㎏, ip) injected 30 min before decreased the inhibition of acetylcholinesterase (AChE) activities in brain, lung and blood induced by parathion (2 ㎎/㎏, ip).(omitted)

Phytoestrogens are naturally occurring compounds derived from plants. Structurally, some phytoestrogens resemble endogenous estrogen of humans and animals. Phytoestrogens exhibit estrogen agonist/antagonist properties and have many biological effects such as prevention of hormone-dependent breast cancer, anti-oxidative activity, inhibition of tyrosine kinase activities and inhibition of angiogenesis. In this study we investigated whether biochanin A, a phytoestrogen, and its metabolites such genistein, p-ethylphenol and phenolic aic affect IL-4 production in EL-4 thymoma cell-line and primary lymph node cells.
