아토피성 피부염은 만성 재발성 염증성 피부질환으로 피부장벽기능의 이상과 환경유발인자에 대한 피부과민성과 연관되어 있다. 이전의 연구에서는 아토피성피부염에 효과적인 약용식물 추출물을 발굴하기 위하여 노회, 자회지정, 석류, 석곡 추출물들의 세포독성, 항산화, 항염, 항알레르기 효과를 검토하였다. 본 연구에서는 지질다당류로 활성화시킨 대식세포 RAW26.7 에 대한 약용식물 추출물들의 항염작용을 보다 상세하게 검토하여 항염작용의 근본적인 분자기전을 확인하고자 하였다. 역전사중합효소연쇄반응분석(reverse transcription polymerase chain reaction analysis) 결과, 석류, 석곡, 노회는 염증성 사이토카인인 IL-6 와 IL-1β 유전자발현을 현저하게 억제시켰으며 자화지정은 영향이 없었다. 형질주입과 발광효소분석(transfection and luciferase analysis) 결과, 약용식물 모두가 전사 핵인자 카파비(NF-kB)의 활성화를 억제시켰다. 웨스턴 블럿 분석(western blot analysis) 결과, 노회는 JNK MAP 인산화효소의 활성화를 차단하였지만 p38 MAP 인산화효소의 활성화는 차단하지 못하였다. 반면에 자화지정, 석류, 석곡은 JNK MAP 인산화효소뿐만 아니라 p38 MAP 인산화효소의 활성화도 차단하였다. 이들 실험결과들은 노회, 자화지정, 석류, 석곡은 항염효능을 가지고 있으며 따라서 아토피성 피부염의 증상을 경감 또는 완화시키는 잠재력이 있음을 보여 준다.

죽의 기능성 향상을 위하여 2:1:1:1의 배합으로 혼합한 한약재료(가시오가피, 숙지황, 산약, 백복령)와 닭가슴살 등의 재료를 사용해 한방 영양죽을 제조하였다. 한방 닭죽의 DPPH radical 소거능, SOD 유사활성, 맛의 선호도, cost는 수학적인 canonical model과 trace plot을 이용하여 분석한 결과, SOD 유사활성 이외에는 각 성분들이 독립적으로 작용하여 상호작용이 없는 선형 모델을 보여주었다. DPPH radical 소거능, SOD유사활성, 맛의 선호도를 최대로, cost를 최소로 목적 범위를 설정하고, 각각의 canonical 계수를 이용하여 수적 최적화를 통하여 최적 배합비를 구한 결과, 한약 혼합물 101 g, 닭가슴살 38.66 g, 찹쌀 비율 41.34 g의 최적 배합비를 구하였으며, 이 배합비에 따른 맛의 선호도는 6.39, DPPH radical 소거능은 17.25 ㎎VCE/ℓ, SOD 유사활성은 2.25%, cost는 1,382.39 won으로 나타났으며, 여러 결과들 사이에 최적화된 한 값에 수렴하는 desirability는 0.714로 나타났다. 이는 한약혼합물이 많을수록 기능성 면에서는 높게 나타나지만 맛의 선호도면에서는 낮게 나타냈고, 닭가슴살의 경우에도 그 함량이 많을수록 맛의 선호도는 올라갔지만 그에 반해 cost가 높게 올라간 것을 반영한 결과로 사료된다.

The objective of this study is investigation of contamination levels and assessment of health risk effects of heavy metals in herbal pills. 31 Items and 93 samples were obtained for this investigation from major herbal medicine producing areas, herbal markets and on-line supermarkets from Jan to Jun in 2010. Inductively coupled plasma mass spectrometer method was conducted for the quantitative analysis of Pb, Cd and As. In addition, the mercury analyzer system was conducted for that of Hg without sample digestion. The average contents of heavy metals in samples were as follows : 0.87 mg/kg for Pb, 0.08 mg/kg for Cd, 2.87 mg/kg for As and 0.16 mg/kg for Hg, respectively. In addition, the average contents of heavy metals in different parts of plants, including cortex, fructus, herba, radix, seed, algae and others were 0.63 mg/kg, 3.94 mg/kg, 1.42 mg/kg, 1.05 mg/kg, 0.16 mg/kg, 22.31 mg/kg and 10.17 mg/kg, respectively. After the estimations of dietary exposure, the acceptable daily intake (ADI), the average daily dose (ADD), the provisional tolerable weekly intake (PTWI) and the relative hazard of heavy metals were evaluated. As the results, the relative hazards compared to PTWI in samples were below the recommended standard of JECFA as Pb 3.1%, Cd 0.9%, Hg 0.5%. Cancer risks through slope factor (SF) by Ministry of Environment Republic Korea and Environmental Protection Agency was 4.24 × 10−7 for Pb and 3.38 × 10−4 for As (assuming that the total arsenic content was equal to the inorganic arsenic). Based on our results, possible Pb-induced cancer risks in herbal pills according to parts used including cortex, fructus, herba, radix, seed, algae and others were 1.95 × 10−7, 1.45 × 10−6, 2.14 × 10−7, 6.27 × 10−7, 1.99 × 10−8, 3.61 × 10−7 and 9.64 × 10−8, respectively. Possible As-induced cancer risks in herbal pills by parts used including cortex, fructus, herba, radix, seed, algae and others were 1.54 × 10−5, 7.24 × 10−5, 1.23 × 10−4, 2.02 × 10−5, 3.25 × 10−6, 2.18 × 10−3 and 5.67 × 10−6 respectively. Taken together, these results indicate that the majority of samples except for some samples with relative high contents of heavy metals were safe.

The present study was evaluated the antibacterial effect of the combination of Coptidis rhizoma, Glycyrrhiza uralensis Fischet, Schizandra chinensis and Corni Fructus(1:1:1) extracts(CGSC10). Furthermore, the effectiveness of CGSC10, sodium chlorate, and the combination of CGSC10 and sodium chlorate(CGSCS10) against E. coli O157:H7 infection was studied using ICR female mice. During the incubation period, the dose of 5, 10, and 20% CGSC10 was inhibited the growth of E. coli O157:H7 by 34.7, 60.2, and 76.4%, respectively. For 7 days after single challenge with E. coli O157:H7, forty female ICR mice were divided into four experimental groups which were administered in drinking water with saline, 10% CGSC10, 15 mM sodium chlorate, and CGSCS10, respectively. On the 3rd day, the number of E. coli O157:H7 in mouse feces was significantly decreased by administration of CGSC10, 15 mM sodium chlorate, and CGSCS10 (p < 0.001). On the 7th day-after administration, CGSC10, sodium chlorate, and CGSCS10 were decreased the number of E. coli O157:H7 by 27.1, 67.7, and 83.3%, respectively. According to the results of the present study, administration of CGSCS10 to mice can reduce the severity of E. coli O157:H7 infection. In addition, it is suggested that CGSCS10 represents a good candidate for the treatment of enteric infections in domestic animals.

This study was performed to investigate contamination levels of aflatoxins, the secondary metabolites produced by fungi Aspergillus flavus and A. parasiticus, in herbal medicine. Herbs is susceptible to these fungi infections through its growth harvest, transport and storage. This study determine the aflatoxin B₁, B₂, G₁ and G₂levels by HPLC-florescence detector coupled with photochemical enhancement in 558 samples herbal medicine distributed in Korea and China. Also, We checked a transfer ratio of aflatoxins from raw herbal medicines to herbal medicine extract. Hot water extraction of herbal medicines was prepared by air pressure and high pressure condition. The analytical method for aflatoxins was validated in this method. In results recoveries of the analytical method were ranged from 67.4% to 96.2% and, limits of detection and quantitation for aflatoxins were 0.015~0.138 μg/kg and 0.046~0.418 μg/kg, respectively. According to the results of monitoring on aflatoxins in herbal medicine, aflatoxins 1.7 ug/kg B1 and 0.9 ug/kg G₁were detected in only one sample of Strychni Ignatii Semen, and 0.8 ug/kg G₁ in Strychni Semen. About 13.6~51.3% of aflatoxins were transferred to hot water extract. Although the detected levels are under the permitted levels for aflatoxins in herbal medicine, these amounts should be considered in regard to overall daily exposure to mycotoxins.

점박이응애(Tetranychus urticae)에 대한 살비활성을 가지는 물질을 알아보기 위하여 약용식물 25과 35 종의 메탄올 또는 헥산 추출물을 이용하여 잎 침지법과 살포법으로 실내와 pot, 야외에서 실험을 수행하였 다. 살비활성은 약용식물 종류별로 차이를 보였다. 강남콩(Phaseolus vulgaris var. humilis) 잎을 1,000 ppm 농도의 추출물에 1분간 침지한 후 점박이응애에 대한 치사율을 조사한 결과, 비자나무(Torreya nucifera) 열매 추출물과 팥꽃나무(Daphne genkwa)와 도꼬마리(Xanthium strumarium), 나팔꽃 (Pharbitis nil) 씨앗 추출물이 각각 56.8%와 47.8, 47.7, 47.7%의 살비활성을 나타내었다. 잎 침지시간을 30초로 단축시켜 점박이응애에 대한 살비효과검정 시는 1분 침지에 비하여 효과가 감소하였고, 나팔꽃과 도꼬마리의 살비 활성이 가장 높았다. 도꼬마리와 나팔꽃 씨앗 헥산 추출물의 반수치사농도는 각각 1,824 ppm과 1,899 ppm이었다. 두 식물의 1,000 ppm 온수 및 냉수 추출물은 점박이응애에 대한 살비효과가 20% 이하로 낮았다.

At 1,000 ppm, extracts of Daphne genkwa flower buds, Eugenia caryophyllata flowers, Quisqualis indica fruits, and Zingiber officinale rhizomes produced >, 80% mortality in J2 juveniles. At 125 ppm, extracts of D. genkwa and Q. indica produced 91 and 99% mortality, respectively. The toxicity of 5 selected plant extracts to M. hapla differed depending on the solvent used (i.e. hexane, methanol, hot water, or cold water). Hot water extracts of Z. officinale and Q. indica produced nematicidal efficacies of99 and 99%, compared to 36 and 98%, respectively, with cold water extraction. Q. indica extract was highly active against M. hapla regardless of extraction method. The inhibitory effects of Areca catechu, D. genkwa, Desmodium caudatum, Pharbitis nil, Q. indica, and Z. officinale extracts on egg hatching of M. hapla was evaluated. At 1,000 ppm, D. genkwa, P. nil, and Q. indica extracts significantly reduced hatching at 7, 14 and 21 days after treatment. Numbers of juveniles in soil treated with the methanol extract

The safety of liquid-type herbal preparations (47 samples) and beverages containing herbal medicines (18 samples), which are distributed in Gyeonggi province was studied by analyzing heavy metals,benzo(a)pyrene, preservatives and sugar content and to explain the differences between medicine and food based on the labeling standards. The herbal preparation is regarded as medicine and can be differentiated from the beverages containing herbal medicine, which is food, based on the fact that the herbal preparation should be labeled with usage,dosage, efficiency and effect. The mean concentrations of Pb, As, Cd, Hg were found to be 0.014 mg/kg, 0.113 mg/kg, 0.004 mg/kg and 0.003 mg/kg in herbal preparation and 0.009 mg/kg, 0.122 mg/kg, 0.003 mg/kg and 0.002 mg/kg in beverages containing herbal medicines, respectively. In 10 cases of herbal preparations and 6 cases of beverages containing Rehmanniae Radix Preparata (Sukjihwang), benzo(a)pyrene was not found. According to preservative test on herbal medicine, dehydroacetic acid was found less than the indicated content in 6 cases out of 37 cases, which labeled with preservatives, and benzoic acid, dehydroacetic acid and methylparaben were contained with 164.0~198.0 mg/kg, 149.8~272.5 mg/kg and 88.4 mg/kg, respectively, in 3 cases out of 10 cases, which was not labeled with preservatives. Among 16 cases of beverages containing herbal medicines, 3 cases of preservative-labeled beverages had the preservatives, and the rest of all, which was not labeled with preservatives, did not show that they contain any preservative, therefore, it was suitable for the labeling standards. As a result of sugar content test, preservative-labeled products were not appreciably different from the others.

The current study was conducted in order to investigate promotional effects of herbal extracts on hair growth in an animal model of mice. There were four experimental groups, including distilled water (DW) as a negative control (NC), 3% minoxidil (MXD) as a positive control (PC), 50% ethanol (EtOH) as a vehicle control (VC), and herbal extract (HE) as the experimental treatment (E). The HE was extracted with ethanol from plants, including Gardenia, Mentha arvensis, Rosemary, and Lavender. Six-week-old C57BL/6 male mice were shaved with an electric clipper and the test materials were topically treated with 0.2 ml per mouse daily for three weeks. Photographic evaluation of hair re-growth was performed weekly during a period of three weeks. The number of mast cells was counted on the dorsal skin section of mice. The enzymes, alkaline phosphatase (ALP) and γ-glutamyl transpeptidase (γ-GT), were determined using a biochemical autoanalyzer. No clinical signs were observed in any of the experimental groups. As a result of photometric analysis, topical application of HE to dorsal skin for two weeks resulted in significantly faster acceleration of hair regrowth, compared with that of the NC or VC group (P<0.05). The PC and E groups showed a significant decrease in mast cell population, compared to the NC group. Activities of ALP and γ-GT were significantly increased in the PC and E groups, compared to the NC or VC group (P<0.05). Taken together, these results suggest that the herbal extract may have hair-growth promoting activity equal to that of MXD.

Atopic dermatitis is a chronic inflammatory skin disease associated with cutaneous hyper-reactivity to environmental triggers. In order to develop effective therapeutic herbal extracts for atopic dermatitis, cytotoxicity, antioxidant, anti-inflammatory and anti-allergic activities were investigated for various herbal extracts. Among candidate extracts, we selected Aloe vera L. (AV), Viola mandshurica W. Becker (VM), Punica granatum L. (PG), Dendrobium nobile L. (DN) and mixture of the above extracts (MX) for further investigations. All of them did not show cytotoxic activities to macrophage RAW264.7 cells below the concentration of 100 ppm. All showed antioxidant, anti-inflammatory and anti-allergic effects, although to various extents. In antioxidant effects, AV showed the highest effect, followed by PG and VM, while DN did the lowest. In evaluation for anti-inflammatory activities in macrophage RAW264.7 cells, AV and DN inhibited almost completely the LPS-induced production of nitric oxide, while AV, DN and VM showed strong inhibitory activities on the LPS-induced production of TNF-α. In anti-allergy effect in mast cell HMC-1, DN showed the highest effect, followed by AV and PG, while VM did the lowest. In the topical allergy reaction induced by compound 48/80 in Sprague-Dawley rat, DN exhibited significant anti-allergic effect, while PG, VM and AV did slight effect. These results suggest that AV, VM, PG and DN have antioxidant, anti-inflammatory and anti-allergic activities, and thus have the potential to reduce and alleviate the symptoms of atopic dermatitis.

The study was conducted to estimate the contents of heavy metal in commercial herbal medicines (1047 samples of 132 species) which were collected from markets in Seoul and to analyze the contents of heavy metals of herbal medicines by classifying them by parts. The samples were digested using microwave method. The contents of heavy metal (Pb, Cd, and As) and Hg were determined using Inductively coupled plasma-Mass spectrometer (ICP/MS). And the contents of Hg were obtained by Mercury analyzer. The average values of heavy metal in herbal medicines were as follows [mean (minimum-maximum), mg/kg]; Pb 0.870 (ND-69.200), As 0.148 (ND-2.965), Cd 0.092(ND-2.010), and Hg 0.007 (ND-0.137). And the average values of heavy metal by parts in herbal medicines were as follows [mean (minimum-maximum), mg/kg]; Ramulus 2.046 (0.065-4.474), Herba 1.886 (0.048-10.404), Flos 1.874(0.052-5.393), Cortex 1.377 (0.011-4.837), Radix 1.165 (0.012-70.111), Rhizoma 1.116 (0.016-5.490, Fructus 0.838(0.017-4.527), Perithecium 0.729 (0.013-4.953), Semen 0.646 (0.006-4.416). The average values of heavy metal of imported herbal medicines except Radix were higher than domestic ones. By decoction of herbal medicines exceeding the tolerances, average intake rates of Pb, As, Cd and Hg were obtained as 6.1%, 40.3%, 4.7%, and 2.2%, respectively.

Wrinkles are an outward sign of cutaneous aging appearing preferentially on ultraviolet B (UVB)-exposed areas. The anti-wrinkle effects of herbal extracts were investigated in an animal model. Female albino hairless mice (HR/ICR) were randomly allocated to the control group (non-irradiated vehicle), positive control group (UVB irradiated-vehicle), and two herbal extract mixture groups (HE-1 and HE-2). HE-1 included Glycyrrhizae radix, Rhei Rhizoma, Cornus officinalis, and Sesami semeni, and HE-2 included Swertia pseudo-chinensis, Sophora flavescens, Scutellaria baicalensis, and Salvia miltiorrhiza. The herbal extract mixtures were pre-treated dorsally with 0.2 ml per individual five times per week for four weeks prior to the start of UVB irradiation. At the fifth week, the animals were exposed to UVB irradiation for a subsequent eight weeks, three times per week. The intensity of irradiation showed a gradual increase, from 30 mJ/cm 2 to 240 mJ/cm2 (1 MED: 60 mJ/cm2 ). Dorsal skin samples were stained with H&E in order to examine the epidermal thickness. In addition, Masson-Trichrome staining was performed for determination of the amount of collagen fiber. Treatments with HE-1&2 resulted in an increase in the amount of collagen fiber, a better appearance, and fewer wrinkles, compared with the positive control. As determined by hydroxyproline assay, treatments with HE-1&2 led to a significant increase in the amount of collagen, compared with the positive control group (p<0.05). Chronic UVB irradiation to skin of hairless mice resulted in an increase in expression of matrix metalloproteinase-1 (MMP-1), however, treatments with HE-1&2 tended to decrease the expression of MMP-1. These results indicate that the herbal extracts used in this study have a preventive effect on UVB-induced wrinkle formation in a hairless mouse model, due in part to inhibition of MMP-1 expression and increment of collagen amount.

The present study was evaluated the antibacterial effect of the combination of Coptidis rhizoma,Lonicerae Flos, and Paeonia japonica (1:1:1) extracts (CLP1000). Also, the effectiveness of CLP1000, dioctahedral smectite (DHS), and the combination of CLP1000 and DHS (CLPS1000) against E. coli O157:H7 infection was studied using ICR female mice. During the incubation period, the dose of 10% and 20% CLP1000 were inhibited the growth of E. coli O157:H7 by 30% and 47%, respectively. For 7 days after single challenge with E. coli O157:H7, forty female ICR mice were divided into four experimental groups which were orally administered with saline, 10% CLP1000, 10% DHS, and 10% CLPS1000, respectively. On the 3rd day, the number of E. coli O157:H7 in mouse feces was significantly decreased by administration of CLP1000 (p < 0.05), DHS (p < 0.05) and CLPS1000 (p < 0.001). On the 7th day, CLP1000 (p < 0.05) and CLPS1000 (p < 0.001) administration significantly decreased the number of E. coli O157:H7. According to the results of the present study, administration of CLPS1000 to mice can reduce the severity of E. coli O157:H7 infection. Also, it is suggested that CLPS100 represents a good candidate for the treatment of enteric infections in domestic animals.

본 연구는 한약재 (결명자, 계피, 산초, 감초) 추출물의 반추위내 발효와 미생물 활성에 대한 효과를 구명하기 위하여 수행되었다. In vitro 건물소화율은 계피와 산초 추출물 첨가구에서는 0시간대, 감초 추출물 첨가구에서는 3시간대에 대조구에 비해 현저히 (P<0.05) 낮았다. 한약재 추출물 첨가에 따른 발효 시간대별 휘발성 지방산 조성의 변화는 3시간대에서만 처리간 유의성이 인정되었는데, acetate 비율은 대조구가 천연 추출물 첨가구보다 유의적으로 높았으나, butyrate, isobutyrate, isovalerate 및 valerate은 대조구에서 가장 낮았다 (P<0.05). 미생물 성장율은 발효 3시간대에서 결명자 첨가구를 제외한 한약재 첨가구에서 대조구에 비해 유의적(P<0.05)으로높았으나다른발효시간대에서는차이가없었다 이상의 결과로부터 한약재로 사용되고 있는 계피, 산초 및 감초 추출물을 in vitro 반추위 배양액에 첨가하였을 때, 발효초기에 반추위 미생물의 활성을 억제하는 경향은 있었으나 미생물 성장에 대한 억제 효과는 없는 것으로 나타났다.
