An important aspect of indigenous medicine is the ability of traditional societis to manipulate the environment for their own benefit, for example for their health care. In Indonesia, this indigenous medicine is called Jamu. Jamu mostly consists of a mixture of herbals of the genus Curcuma, Zingiberaceae. There are 19 species of curcuma grown in Indonesia. Eleven of them are popular in the jamu preparations. Ethnopharma-cological surveys have shown that 50% of these species are used for post partum protection, dismenorrhea, 30% are used for the treatment of stomache and as cosmetics, 20% for the treatment of various diseases such as fever, worms, asthma, etc. Chemical studies show that they contain curcuminoids, volatile oils, flavonoids, starch, and resinous substance. Pharmacological studies of extracts and isolated bioactive compounds have shown that they have a broad pharmacological activity such as antibacterial, antifungal, anti-inflammatory, choleretic, antihepatotoxic, antitumor, antioxidant, and antihyperlipidemic activity.

The acute and subacute toxicities and pharmacological actions of two preparations of Ssanghwa Tang prescriptions have been evaluated in mice, rats and rabbits. The two prescriptions were found to be safe drugs because those preparations exhibited almost no acute and subacute toxicities even at a high dosage level. The two prescriptions elicited CNS depressant activities characterized by potentiation of hexobarbital-induced narcosis, antipyretic activity in typhoid-vaccinated rabbits and a significant antifatigue effect against cold immobilized stress, the activities of prescription B being more potent.

Hijikia fusiforme (HF), a member of brown algae family, exerts various pharmacological effects, including preventing arteriosclerosis and menopausal disorders. This study aimed to elucidate the ameliorative effect of HF on skin inflammation. We investigated the antioxidant and anti-inflammatory effect of HF extract to evaluate its potential as a functional materials. The antioxidant activity of HF was determined using 2,2-diphenyl-1-picrylhydrazy (DPPH) scavenging and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS+) scavenging. To determine the pharmacological mechanism of HF in inflammatory reaction, we evaluated the effects of HF on interleukin (IL)-8, IL-6 and tumor necrosis factor (TNF)-α production and nuclear factor-κB (NF-κB) activation in activated- human mast cells (HMC)-1. Results showed that HF had the high DPPH and ABTS+ radical scavenging activity, and it suppressed IL-8, IL-6 and TNF-α production in a concentration-dependent manner. Moreover, HF significantly ameliorated NF-kB activation in activated-HMC-1. Hence, these results provide evidence that HF's potential for skin inflammation therapy.

Saponin isolated from Sapindus mukorossi Gaertn has been shown to contain a strong anti-inflammatory activity. In this study, several pharmacological properties such as acute toxicity, local irritation and hemolytic activity of Sapindus saponin and its genin component, hederagenirl, were examined. The acute toxicity of Sapindus saponin was very low. Estimated from the LD$_{50}$ values, it showed much weaker toxicity in oral administration than in intraperitoneal injection. Hederagenin gave a very high LD$_{50}$ value even in intraperitoneal injection. Sapindus saponin showed a potent local irritation after topical application, whereas hederagenin did a very weak local irritation. Sapindus saponin also gave a high hemolytic activity.

The general and some pharmacological actions of DWP 301 were investigated in animals and the following results were obtained. In central nervous system, DWP 301 had no effects on the pentobarbital induced anaesthesia, rotarod test, traction test, analgesic action, anticonvulsant action in mice and body temperature in rat. But DWP 301 showed a little decrease of locomotor activity at a dose of 3,000 mg/kg. From these results, DWP 301 was considered to have little pharmacological effect on the central nervous system. Furthermore, DWP 301 had no influences on the normal blood pressure and heart rate. DWP 301 showed no effect on the isolated guinea pig ileum, trachea, right atrium, and nonpregnant rat uterus. But, in the isolated guinea pig vas deference, DWP 301 had showed inhibitory effect on the contractions produced by norepinephrine. DWP 301 showed rise of gastric juice pH and decrease of urine volume. Also, DWP 301 had no effect on the gastrointestinal motility and blood aggregation. From these results, it is concluded that the general pharmacological effect of DWP 301 are similar to or weaker than M and AGA.

In this study, we developed an assay system for missense mutations in human phenylalanine hydroxylases (hPAHs). To demonstrate the reliability of the system, eight mutant proteins (F39L, K42I, L48S, I65T, R252Q, L255V, S349L, and R408W) were expressed in a mutant strain (pah^-) of Dictyostelium discoideum Ax2 disrupted in the indigenous gene encoding PAH. The transformed pah - cells grown in FM minimal medium were measured for growth rate and PAH activity to reveal a positive correlation between them. The protein level of hPAH was also determined by western blotting to show the impact of each mutation on protein stability and catalytic activity. The result was highly compatible with the previous ones obtained from other expression systems, suggesting that Dictyostelium is a dependable alternative to other expression systems. Furthermore, we found that both the protein level and activity of S349L and R408W, which were impaired severely in protein stability, were rescued in HL5 nutrient medium. Although the responsible component(s) remains unidentified, this unexpected finding showed an important advantage of our expression system for studying unstable proteins. As an economic and stable cell-based expression system, our development will contribute to mass-screening of pharmacological chaperones for missense PAH mutations as well as to the in-depth characterization of individual mutations.

Objectives : Herbal medicines were used a lot in the Northeast Asia, traditionally. However, the pharmacopoeia standards in South Korea, China, Japan, Taiwan, and North Korea including many other Asia are different and cause confusion. If the origins are not belonging to same genus, it should be careful to distinguish. In this study, herbal medicines in the pharmacopoeia were analyzed for different genus of origins in order to identify the disruptive items for each country. Methods : The scientific names of herbal medicines (plant based) was analyzed origins from Pharmacopoeias of Republic of Korea, People's Republic of China, Japan, Taiwan, and Democratic People's Republic of Korea. The origins specified differently were examined. Especially, the items which have different genus were analyzed in detail and confirmed for correct scientific name. Results : The analyzed herbal medicines in Pharmacopoeia were all 753 items. 320 items were in only one country's Pharmacopoeia. 237 items were in more than two countries' Pharmacopoeia, but their origins were same on each other. The items which have different genus were 35 items. Conclusions : In general, species belonging to the same genus have similar ecological, morphological, and pharmacological activity. However, species with different genus may have different medicinal ingredients and pharmacological activity. Thus, the items which have same name but different genus are required to analyze for comparison of pharmacological activity. Also, other species belonging to the different genus should be used for different items.

Restriction endonucleases play an important role in molecular cloning, clinical diagnosis, and pharmacological drug studies. In this study, DNA-templated copper nanoclusters (DNA-CuNCs) were used to detect AluI endonuclease activity due to their high fluorescence emission and rapid synthesis of DNA-CuNCs under ambient conditions. Results showed that AluI activity was detected in a highly sensitive manner at low concentrations of AluI endonuclease by the fluorescence intensity of DNA-CuNCs. Additionally, its inhibition was monitored in the presence of daidzein under optimal conditions.
