Recent evidence suggests that many Oriental Medicinal prescriptions are effective in cancer patients as a supportive care. Oriental Medicinal herbs have been investigated extensively and are known to have multiple pharmacological effect. These herbs contain a variety of ingredients which may act synergistically to inhibit tumor cell division, to increase tumor cell death (apoptosis), and to increase the proportion of immune cells within tumor. Paljinhangahm-dan (Paljin) has been used to treat for cancer patients in Oriental Medicine for decades. The effects of aqueous extract of Paljin on the induction of apoptotic cell death were investigated in human leukemia cell lines (HL-60, Jurkat, Molt-4 and U937). The viability of leukemia cells was markedly decreased by Paljin in a dose-dependent manner. Paljin induced the apoptotic death of leukemia cells, which was characterized by the ladder-pattern DNA fragmentation, and chromatin condensation of the nuclei. Paljin digested Bid protein but did not affect Bcl-2 protein level and also, induced mitochondrial dysfunction disrupted as shown as the mitochondrial membrane potential. It activated caspase-9 and caspase-3. thereby resulted in cleavage of poly(ADP) ribose polymerase(PARP). These results indicate that Paljin induces apoptosis of human leukemia cells via activation of intrinsic caspase cascades with mitochondrial dysfunction.

Objectives : This study examined the possibility of therapeutic application of natural pigments in the Joseon Period other than aesthetic purposes. Methods : The medicinal properties of natural pigments as written in the texts Sangayorok, Gyuhapchongseo, Imwongyeongjeji were searched and analyzed in the texts Bencaogangmu, Encyclopedia of Eastern Medicine, and the Encyclopedia of Chinese Medicinals focusing on their Qi, flavor, effects and application. Of the conditions they treated, we examined whether they treated skin conditions using external application. The Korean Medical effects of these pigments were examined based on the content of the skin chapter of the Donguibogam. Results : We were able to extract 47 kinds of natural pigments, most of which had cold nature and bitter tasting properties. In addition, most of the pigments had the effect of treating skin conditions, illnesses due to micro-organisms, and of detoxifying. Conclusions : After consideration of medicinal properties and effects of the herbs that were used as pigments in the Joseon period, it could be concluded that as these herbs not only function as pigments but also hold properties that prevent skin conditions, their therapeutic functions could have been considered when using them as pigments.

Astragali Radix (AR) has been used in traditional medicinal herb, which is known to tonify the qi and blood. It has been asserted to be a tonic that can improve the function of the lungs, adrenal glands and the gastrointestinal tract, increase metabolism, promote healing and reduce fatigue. Also, Plantago asiatica (PA) has the anti-inflammatory, antiseptic, antitussive, cardiac, diuretic, expectorant, haemostatic effects, though it is considered to be less powerful than the seed. Recent research is showing that it is promising in lowering cholesterol and controlling diabetes. Obesity is characterized at the cellular level by an increase in the number and size of adipocytes differentiated from fibroblastic preadipocytes in adipose tissue. In the present study, we investigated the effects of 3 to 7 extracts of mixed medicinal herbs (water and ethanol extract of Astragali Radix; ARW and ARE, water and ethanol extract of Plantago asitica; PAW and PAE, and those mixed extracts; ARW+PAE, ARW+PAW and ARE+PAE) on adipogenesis and apoptosis in 3T3-L1 adipocytes by MTT assay, Oil-Red-O staining and TUNEL assay. And then, we determined total contents of phenolic compounds and flavonoid compounds in mixed herbal extracts. These result showed that herbal extracts (ARW, PAE and ARW+PAE) affected on adipogenesis and apoptosis in 3T3-L1 adipocytes among 3 to 7 extracts tested. Especially herbal mixed extracts (ARW+PAE) had the highest inhibition on differentiation of preadipocytes and lipoid accumulation of maturing adipocytes. And it did not affect cell viability of mature adipocytes, but herbal mixed extracts (ARW+PAE) increased apoptosis in mature adipocytes, as proved by highest concentration $200\;{\mu}g/m{\ell}$ using TUNEL assay. In addition, contents of total phenoilc compounds and flavonoids showed the highest level in ARE+PAE and PAE than ARW. These results suggest that this main target for adipocyte functions could be effective in improving the metabolic syndrome including obesity.

We investigated the effects of manufacturing method on the quality of beef jerky using electron micrography. Six types of beef jerky were prepared by the addition of sugar (A), licorice (B), one of three kinds of spice extract (clove: C, fennel fruit: D, and Chungyang green pepper extract: E), or a mixture of all spice extracts (F). Microstructural changes in beef jerky during preparation by drying, with respect to drying method and the nature of the added spice extract, were observed by scanning electron micrography (SEM) and transmission electron micrography (TEM). The latter technique showed that the microstructure of fresh meat showed actin and myosin in myofibril lines, and also mitochondria and inner membranes. Beef muscle structure was broken at many myofibril lines and decomposition of inner membrane material was evident after seasoning. SEM of air-blast dried beef jerky with added medicinal herb extracts showed both large spaces and regular myofibrils, whereas hot air-dried beef jerky had no spaces and the muscle myofibrils were still evident. After review of all available micrographs from SEM and TEM, we concluded that use of medicinal herb extracts could be helpful in preserving the muscle myofibril structure during drying, and the air-blast drying method is recommended to optimize the textural quality characteristics of beef jerky.

When inflammatory reaction is in progress, the macrophages release inflammatory cytokines, such as interleukin-6 (IL-6), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), and product inflammatory mediators, including inducible nitric oxide synthase (iNOS) and prostaglandin E2 (PGE2). We conducted this study to evaluate the anti-inflammatory efficacy on each water extract of Acanthopanacis cortex, Achyranthes radix, and Eucommiae cortex, and to investigate whether they inhibit the expression of pro-inflammatory cytokine. Acanthopanacis cortex, Achyranthes radix, and Eucommiae cortex were extracted with water and freeze-dried. Acanthoside D, 20-hydroxyecdysone, and pinoresinol diglucoside as an index material were analyzed by high-performance liquid chromatography (HPLC) to ensure that the components of each extracts were extracted well. RAW 264.7 cell line, stimulated with lipopolysaccharide (LPS) to cause an inflammatory response, was treated with each water extract at various concentrations to determine the anti-inflammatory efficacy. Then, the anti-inflammatory efficacy was confirmed by a nitric oxide (NO) assay, and the mRNA expression levels of pro-inflammatory cytokines were measured by real time PCR. As a result, the indicator materials were detected from each extract, and Acanthopanacis cortex water extract (ACWE) and Achyranthes radix water extract (ARWE) were shown to have a high activity than Eucommiae cortex water extract (ECWE) in NO assay. In Korea, traditionally it prescribed a combination of medicinal herbs. This study confirmed the anti-inflammatory response of these medicinal plants in arthritis and its synergistic effect when used in combination with western medicine.

To develop an effective anti-hangover product, hot-water extracts of 25 medicinal herbs were screened for inhibition or activation of alcohol dehydrogenase(ADH) and acetaldehyde dehydrogenase(ALDH), and 12 herbs were selected for further study. Chosen medicinal herb extracts(CMHEs) were fermented by Lactobacillus delbruechii subspecies lactis for 10 days at $35^{\circ}C$ after saccharification with nuruk(malt inoculated by 5 types of microbs) for 72 hours at $35^{\circ}C$ and both CMHEs and fermented CMHEs(FCMHEs) were explored for anti-hangover effects in vitro. We found significant ADH inhibition by hot-water extracts of Pueraria thunbergiana, Hovenia dulcis Thunb, Lycium chinense, Glycyrrhiza uralensis, Acanthopanax sessiliflorus, Liriope platyphylla, and Ixeris dentata, and significant ALDH activation by extracts of Acanthopanax sessiliflorus, Lycium chinense, Ixeris dentata, and Polypori umbellati of the Polyporaceae. The ADH effects on CMHE and FCMHE were -20.22% and -62.63% of control values, and the ALDH effects 173.20% and 280.17%, respectively. In rats given 20%(v/v) alcohol(15 mL/kg), FCMHEs significantly decreased blood acetaldehyde concentrations on 3 hours after ethanol administration, in a dose-dependent manner(p<0.05). Notably, blood acetaldehyde concentrations were markedly reduced in animals given FCMHEs(400 mg/kg) compared to levels seen in rats receiving CADB(commercial alcohol detoxification beverage). Thus, anti-hangover effects were promoted by fermentation of certain medicinal herb extracts.

According to the Chinese and Korean medicinal and herbal literature, SSG(Silsosangami) is effective for the treatment of inflammation, hyperlipemia and arteriosclerosis. The pharmacological action of SSG has been limitedly studied in regard to ischemic infarction. This herbal medicine has been shown to express diverse activities such as immunomodulating, anti-infarction, anti-allergic and anti-inflammatory effects. Antisclerotic effects of SSG in experimentally induced atherosclerosis in rabbits have also been reported. However, pharmacological mechanisms of SSG on lipid metabolism and atherosclerosis formation are poorly understood. The present paper reports the effect of extracts obtained from SSG on endotoxin-induced experimental DIC in rats. Also, these were tested for their effect on endotoxin-induced blood platelet aggregation, thrombin-induced conversion of fibrinogen and fibrinolysis in vitro experiments with aspirin as a positive agent. The anti-thrombic properties of SSG were also investigated by means of analytical parameters of bood composition. The extracts of SSG and its seven herbs, except Cnidii Rhizoma and Carthami Flos, inhibited the endotoxin-induced DIC and thrombosis in rats. Also the extract inhibited the endotoxin-induced decrease in blood platelets and fibrinogen, and endotoxin-induced increase in fibrin degradation products (FDP) on disseminated intravascular coagulation in normal rats.

Objectives: The purpose of this study was to evaluate the neuroprotective effects of donepezil and 33 kinds of herbal extract combinations in SH-SY5Y cells with $A{\beta}_{25-35}$ treatment. Methods: MTT assay was performed to measure the cell viability of each herbal extract combined with donepezil against $A{\beta}$-induced neurotoxicity. The most active extracts were then subjected to assess the effects on CREB phosphorylation and COX-2 expressions through the western blot analysis. Results: There were eight herbal extracts representing significant increase on the cell viability: 1) Erycibe obtusifolia, 2) Polygonum multiflorum, 3) Polygala tenuifolia, 4) Illicium verum, 5) Santalum album, 6) Loranthus parasticus, 7) Platycladus orientalis, and 8) Zanthoxylum piperitum. Especially, when Santalum album and donepezil were treated together, the phosphorylation of CREB significantly increased and COX-2 protein expression was significantly inhibited. Conclusions: Among the screened herbal extracts, combination treatment of each of the eight herbs and donepezil showed neuroprotective effects in SH-SY5Y cells. Additionally, the combination of Santalum album and donepezil suggested cognitive improvement by up-regulation of p-CREB and down-regulation of COX-2.

Agastachis herba is so similar in use to herbs that it is called Korea Mint in the West. Western herbs are commonly used as ingredients in cosmetics. However, in Korea, Agastachis herba is primarily used as a medicinal herb. This study aims to compare the effectiveness of one cosmetic ingredient with another cosmetic ingredient. Antioxidant, whitening, polyphenol, flavonoid, and antibacterial experiments were conducted on lactobacillus, yeast ferments, essential oils, and floral water using extracts from Agastachis herba. Antioxidants exhibited significant effects in all samples, while essential oils displayed the highest efficacy in terms of whitening, polyphenol content, and antibacterial properties. Flavonoids exhibited the strongest effect in the 70% ethanol extract. The essential oil had the most significant functional impact. However, it was confirmed that the fermented products that underwent yeast fermentation with extracts were as effective as essential oils.
