The leaves (Mori Folium; MF), branches (Mori Ramulus; MR), and root bark (Mori Cortex Radicis; MCR) of the mulberry tree have been used as therapeutic herbs for centuries. Existing analytical methods were developed specifically for different parts of the tree and cannot be applied to samples containing a mixture of tree parts. Such method specialization is time-consuming and requires separate identification and quality control of each tree part. This report describes an HPLC method for the simultaneous quality control and discrimination of MF, MR, and MCR using four marker compounds: rutin, kuwanon G, oxyresveratrol, and morusin. An Optimapak $C_{18}$ column ($4.6{\times}250mm$, $5{\mu}m$) was used with a gradient elution of 0.1 % formic acid in water and acetonitrile. The flow rate was 1.0 mL/min and the detection wavelength was 270 nm. In quantitative analyses of the three parts, rutin (0.11 % w/w) was detected only in MF. The oxyresveratrol content (0.12 % w/w) was highest in MR. Kuwanon G (0.33 % w/w) and morusin (0.18 % w/w) were higher in MCR than in other parts. The HPLC method given herein can be used to simultaneously classify and quantify three herbal medicines from the mulberry tree.

Extracts from Asian medicinal herbs are known to be successful therapeutic agents against cancer. In this study, the effects of three types of herbal extracts on anti-tumor growth were examined. Among the three types of herbal extracts, H9 showed stronger anti-tumor growth effects than H5 and H11 in vivo. To find the molecular mechanism by which H9 inhibited the proliferation of breast cancer cell lines, the levels of apoptotic markers were examined. Proapoptotic markers, including cleaved PARP and cleaved caspases 3 and 9, were increased, whereas the anti-apoptotic marker Bcl-2 was decreased by H9 treatment. Next, the combined effect of H9 with the chemotherapeutic drugs doxorubicin/cyclophosphamide (AC) on tumor growth was examined using 4T1-tumor-bearing mice. The combined treatment of H9 with AC did not show additive or synergetic anti-tumor growth effects. However, when tumor-bearing mice were co-treated with H9 and the targeted anti-tumor drug trastuzumab, a delay in tumor growth was observed. The combined treatment of H9 and trastuzumab caused an increase of natural killer (NK) cells and a decrease of myeloid-derived suppressor cells (MDSC). Taken together, H9 induces the apoptotic death of tumor cells while increasing anti-tumor immune activity through the enhancement of NK activity and diminishment of MDSC.

This study was conducted to determine if YJ-1, a novel herbal complex from a mixture of six oriental herbs (Hydnocarpi Semen, Sesami Semen, Dictamni Radicis Cortex, Momordicae Semen, Xanthii Fructus, and Sophorae Radix), has therapeutic properties for the treatment of atopic dermatitis (AD). Using AD like symptom-induced NC/Nga mice by 1-chloro 2,4-dinitrobenzene (DNCB), the effectiveness of YJ-1 on AD was evaluated. Elidel cream$^{(R)}$ (1% pimecrolimus) was used as a control. Dermal application of YJ-1 reduced major clinical signs of AD such as erythema, pruritus, lichenification, edema/escoriations, and dryness. Interestingly, YJ-1 more improved AD-related symptoms including decrease of spleen weight, IL-4, and IgE level in the serum as well as reduction of scratching counts and clinical skin severity in the NC/Nga AD mouse model. Especially, treatment of YJ-1 at 20% in NC/Nga mice more effected than Elidel cream. These results suggest that the ointment of YJ-1 may enhance the process of AD healing by alleviating allergic reaction and has potential for therapeutic reagent for the treatment of AD.

Objectives: This study is an overview of the meta-analysis and systematic review of randomized controlled trials investigating the clinical effectiveness and safety of pharmacopuncture for patients with stroke. Methods: Core electronic databases were searched from their inception to 21 May 2019. A measurement tool to assess systematic reviews (AMSTAR 2) was applied to screen high-quality studies. The results of these studies were summarized, and additional meta-analysis was conducted. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) was used to evaluate the certainty of evidence. Results: Sixteen studies met eligibility criteria. Four were excluded owing to insufficiency of AMSTAR 2 or low data reliability. The finally selected 12 studies were about pharmacopuncture using either a single herb extract, such as Dengzhan xixin, Sanch, Ginkgo biloba, or Acanthopanax, or a mixture of herbs, such as Compound danshen, Shenxiong, Xingnaojing, or Mailuoning. Most of the patients were from China, with acute ischemic stroke. All the studies using a pharmacopuncture versus a non-pharmacopuncture design reported the significant superiority of pharmacopuncture on every outcome measure. On the other hand, in a few studies, pharmacopuncture was inferior to active control in improving neurological deficit. Few studies reported adverse events. Conclusions: It is difficult to apply the results of this study directly to Korea, because the level of evidence is generally low and the clinical settings and social acceptance of pharmacopuncture therapy differ in Korea and China. Further studies are warranted to confirm the domestic applicability of evidence generated in China and to create evidence that supports the domestic situation.

Background: Galgeun-tang used in traditional Korean medicine, is a mixture of the medicinal plants Cinnamomi Ramulus, Ephedrae Herba and Puerariae Radix, and has been prescribed for the treatment of various ailments, including fever. Although the use of traditional medicinal herbs to treat diseases has recently increased, their safety and toxicity profiles incompletely elucidated. Thus, we evaluated Galgeun-tang's toxicity in male and female Sprague-Dawley rats. Methods and Results: Galgeun-tang (1,000, 2,000 and 4,000 mg/kg) was orally administered to rats for 13 weeks, and then, they were maintained for 4 weeks without administration (recovery period). Their clinical signs, and hematological and urinary properties, were monitored. The results showed that Galgeun-tang administeration slightly increased serum creatinine, urea nitrogen and, aspartate aminotransferase levels. Additionally, 2,000 and 4,000 mg/kg Galgeun-tang significantly increased urinary bilirubn and protein levels of male and female rats, which were restored during the recovery period. Conclusions: The no-observed-adverse-effect level of orally administered Galgeun-tang was 4,000 mg/kg in both female and male rats, and no target organs were identified. In addition, 400 mg/kg was found to be the no-observed-effect level for toxicity under the study conditions.

GCSB-5 is a purified extract from a mixture of 6 Oriental herbs (Ledebouriellae Radix, Achyranthis Radix, Acanthopanacis Cortex, Cibotii Rhizoma, Glycine Semen, and Eucommiae Cortex) that have been widely used for the treatment of inflammatory diseases in the East Asia. The aim of this study was to investigate the anti-inflammatory potential of GCSB-5. The animals used in this study were administered either vehicle or GCSB-5 (30, 100, 300, and 600 mg/kg) orally. The GCSB-5 significantly inhibited the increased of acetic acid-induced vascular permeability (30.9%-34.2% inhibition at 30-300 mg/kg). The swelling of the rat's hind paw induced by carrageenan was significantly inhibited by GCSB-5 in doses of 100, 300, and 600 mg/kg. Maximal inhibition (50.9%) was obtained with GCSB-5 at dose of 300 mg/kg. However, it did not have any anti-inflammatory action in the rheumatoid arthritis induced by Freund's complete adjuvant or in the granuloma induced by carrageenan. Our finding suggest that GCSB-5 has a anti-inflammatory activity.

The HWND_G02 (Salvia miltiorrhiza Bunge, Crataegus pinnatifida, Polygonum multiflorum Thunberg, Cnidium officinale Makino) and HWND_G03 (Cinnamonum cassia Blume, Salvia miltiorrhiza Bunge, Crataegus pinnatifida, Polygonum multiflorum Thunberg, Cnidium officinale Makino, Allium macrostemon Bunge) are new natural mixture composed with several oriental herbs. The aim of the present study was to investigate the effects of HWND extracts on high cholesterol diet (HCD)-induced hyperlipidemic rats. Male Sprague-Dawley rats were divided into five groups: control, HCD, atorvastatin (5 mg/kg, po), ethanolic extracts of HWND_G02 (1,000 mg/kg, po) and HWND_G03 (1,000 mg/kg, po) were administered to the HCD-induced hyperlipidemic rats for 4 weeks to evaluate their anti-hyperlipidemic activities. HWND extracts markedly decreased body and liver wight gain, and recovered serum lipid levels, such as total cholesterol (TC), triglycerides (TG), low density lipoprotein-cholesterol (LDL-C) and high density lipoprotein-cholesterol (HDL-C) in the HCD-induced hyperlipidemic rats. Furthermore, the lipid levels (TC and TG) and the lipid accumulation were significantly lowered in the liver tissue of HWND-administrated rats. After a HCD, each group had a lower atherogenic index (AI) compared to the HCD group. In conclusion, these data suggest that HWND extracts could be the candidate for the material to prevent hyperlipidemia.

Acceptable fish noodles of better nutritional and sensory values than conventional noodle made only wheat flour were prepared by mixing wheat flour and ground tile fish (Branchioste gus japonicus). In oder to mask a distinctive fish odor, various herbs and spices, such as ginger (Zingiber officinale), curry (Chalcas koenigii), nutmeg (Myristica Pagrans), garlic (Ailium sativum), black pepper (Piper nigrum), lemon (Cirtus limon) or sodachi (Citrus sudachi) were added to the basic tile fish noodle. Also, for the purpose of enhancing eating qual ify and nutritional value of basic noodle were combined some agricultural or fishery products of Cheju island, citrus fruits; danyooja (Citrus danyooga), hagul (C. natfudaidai), medical plants; angelica utilis (Angelica keiskei), ginseng (Panax ginseng), cactus (Opuntia dillenii), vegetable; carrot (Daucus carota), dropwort (Oenanthe jnvanica), seaweeds; fusiforme (Hizkia fusiforme), gulfweed (Sargaceae hlvelium). The optimal mixing ratio for preparing the basic tile fish noodle amounted to ground tile fish 135 g: tile fish stock 139 $m\ell$: wheat flour 450 g: salts 10 g. The mixture of curry powder (2.5 g) and nutmeg powder (2.5 g) was proved to be the most effective combinations for masking unfavorable fish odor. The optimal amounts of materials to be added to the prepared basic noodle were 25 g citrus zest and 80m1 citrus juice for citrus fruits noodles, and ca. 140 g puree for noodles from medical plants, vegetables and seaweeds, respectively. The preference score obtained from consumer preference test, on a 9-point scales, were in oder of i) danyooja > carrot, angelica, ginseng > fusiforme, ii) hagul > dropwort, cactus > gulfweed. The shelf-life of tile fish noodle based on bacterial counting was estimated to be 7-days at 5$^{\circ}C$.

This study was conducted to develop recycle revegetation methods for the restoration of the steep slopes by using fresh wood chip from construction sites. In general, the fresh wood chips can be used as soil media for the restoration works, because they can increase infiltration of rainfall and give enough porous to breathe and elongate for the root growth as well as economic value. The experiment was carried out to compare the effect of fresh wood chips from different mixing with soil, organic material and macromolecular compound which used for slope restoration works conducted by Hyunwoo green(Ltd.). The main results by monitoring for two years are summarized as follows; 1. The soil media made with low percentage of fresh wood chip covered quickly by herb plants. Especially, the soil mixture Type C (wood chip 20%) showed 80 percent ground coverage within two months after seeding. 2. The soil mixture type E (wood chip 40%) and type F (wood chip 50%) which contains more fresh wood chips than soil type C was under 30 percent ground coverage because wood plants are germinated well. If the restoration works aims at making forest, then the soil type E and F would be recommended than using soil type C. 3. Among the woody plants, Ailanthus alfissima, Pinus rigida, Pinus densiflora, and Albizzia julibrissin showed high percentage of germination rates and vigorous growth. In case of shrubs, Lespedeza cyrtobotria and Indigofera pseudo-tintoria scored high percentage of germination rates. 4. In native plants, Chrysanthemum indicum, Artemisia princeps, Lutos corniculatus and Imperata cylindrica showed high percentage of appearance. In case of introduced herbs, Coreopsis lanceolata, Coreopsis tinctoria and Oenothera oborata grew so vigorously. 5. The soil types which including fresh wood chips over 30-40 percentage showed the most diverse plant composition and the most effective germination rates and growth pattern with woody plants. 6. This works to develop recycle revegetation methods using fresh wood chips need more efforts for monitoring the exact effect of fresh wood chips as the soil media.

It has been reported that various kinds of chinese herbs have an activity of promote growth rate in both animals and human. To investigate the growth promoting effect of the selected plants, fish and pigs were used as experimental animals. In fish, Eleutherococcus senticosus extract and Artemisia capillasis extract were found to be most effective. And these plant extracts were given to pigs. The result showed that plant extracts-fed pigs were significantly increased their body weight gain at 7.06% of average daily gain, as compared to control. The verify this results, secreted growth hormone (GH)levels and insulin-like growth factor-1 (ICF-1) levels into blood were measured. This result indicated that GH and IGF-1 levels in the blood in plant extracts-fed pigs were higher that those of control. To confirm growth promotion effect on human, we manufactured the mixture of these plant extracts, and coated this mixture onto rice, named as $Kiwoomi^{TM}$. When we administered $Kiwoomi^{TM}$ to elementary students, it was found to be effective in growth promotion. This result showed that $Kiwoomi^{TM}$-treated elementary students significantly increased their growth rate (about 2.14 times), as compared to untreated children. Taken together, it is suggested that this functional rice ($Kiwoomi^{TM}$) might be helpful for growing children without any side effects.
