Objectives Children's unique taste bud often gives them difficult time to take oriental medicines. To overcome, survey was conducted focusing on useful and practical tips on how to take them. Methods The survey was carried out by posting mail questionnaire. Target clinics for the survey were selected by the internet search engine, Google, Daum, and Naver, and typing in "oriental treatment + pediatrics", "pediatrics + oriental medicine", "pediatric oriental clinic". 24 clinics were searched, but they were further narrowed down to the specialized pediatric oriental clinics. Also, total of 38 inquiry leaflets were distributed to 14 University Oriental Hospitals. Results If children refuse to take the medicine, mixture with sweeteners can be prescribed for them. Among them, oligosaccharide is the most recommended followed by sugar and honey. To avoid rejection to medication, use of different formulation, such as distillation medicine, soft X-Section, granulated medicine, and character printing can be used. Conclusions The most effective method is to investigate the mixture first, and then the alternative formulations.

This study aimed to evaluate the anti-atherosclerotic and anti-hypertensive effects of six different plant extracts using a N(G)-nitro-L-arginine-methyl ester (L-NAME)-induced rat model of hypertension. All extracts were administered orally for six weeks. At the end of the study period blood pressure, blood flow, aortic histopathology, and hepatic endothelial nitric oxide synthase (eNOS) expression were measured. Subsequently, we also measured the levels of intracellular reactive oxygen species, nitric oxide (NO), and anti-inflammatory cytokines in vitro. Based on these screening results, we selected extracts of Cinnamomum cassia (C. cassia) and Salvia miltiorrhiza (S. miltiorrhiza) for further evaluation. C. cassia and S. miltiorrhiza extracts ameliorated hypertension and atherosclerosis in L-NAME-treated rats in a dose-dependent manner. In addition, a mixture of C. cassia and S. miltiorrhiza had an additive effect to reduce blood pressure, increase blood flow, and normalize aortic tissue. This mixture demonstrated anti-oxidative and anti-inflammatory activities in vitro. In conclusion, although further analysis of the therapeutic mechanism is required, the anti-hypertensive and anti-atherosclerotic effects of this mixture are likely mediated by increased eNOS expression, and its anti-oxidative and anti-inflammatory activities.

Fatty liver hemorrhagic syndrome (FLHS) is a metabolic disorder found in caged layer hens and causes reduced egg production and sudden death. Dandelion (Taraxacum coreanum, TC) and milk thistle (Cirsium japonicum var. ussuriense, CJ) are well known wild herbs inhabiting Korean peninsula and presenting antioxidative effects. This study investigated alleviate effects of these herbal mixture (6:4, w/w) composed of dried powder of TC and CJ against fatty liver in laying hens. The herbs mixture 5.0, 10.0, 20.0 or 40.0 g/kg feed was provided via feed admixture for 3 weeks to laying hens having FLHS. FLHS was induced by intramuscular injection of β-estradiol (2 mg/kg bw) 2 times per week for 3 weeks and supply with high caloric feed. Egg production rate was reduced from 76.2% at pre-treatment to 49.4% at 1 week and further decreased according to β-estradiol treatment. Increment of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), total cholesterol (T-Chol) and total bilirubin (T-Bil) and decrement of serum superoxide dismutase (SOD) and glutathione peroxidase (GPX) with fatty liver were found by the treatment of β-estradiol. Supplementation of TC and CJ mixture via feed admixture recovered the reduction of egg production and attenuated serological changes and gross and pathological lesions of fatty liver with the best amelioration effects at 5 and 10 g TC and CJ mixture per kg feed. In conclusion, TC and CJ mixture attenuates FLHS by means of antioxidative effects. Further mechanistic study is required to explain TC and CJ's amelioration effects against FLHS in laying hens.

The purpose of this study was to evaluate the control efficacy of major environment-friendly control agents against powdery mildew, as affected by the application condition such as disease-developing stage and microclimate, as compared with the efficacy of pesticides in plug seedling of three Cucurbitaceae vegetables, including cucumber, melon, and oriental melon. Single or combined application of major six environment-friendly control agents was used in the experiment: two biofungicide (Ampelomyces quisqualis 94013 and Bacillus subtilis Y1336), two plant extracts (neem oil and extracts of Rheum undulatum), and two mineral materials (wettable sulfur powder and lime bordeaux mixture). These control agents were treated to the plug seedlings for preventing powdery mildew and curative applications for managing powdery mildew. In all treatments, the disease incidence declined as daily average temperatures increased to $30^{\circ}C$ for consecutive 6~8 days with maximum temperature over $40^{\circ}C$. In preventative application, the control efficacy against powdery mildew was the highest in the treatment of wettable sulfur powder, and lowest in the B. subtilis Y1336, with values of 20~40%. In cucumber seedlings, the preventive single application of neem oil or wettable sulfur powder was more effective than curative application of fungicides, while the control efficacy of these agents was similar to those of fungicides in melon seedlings. The single application of R. undulatum extracts was also effective in preventing the disease for both cucumber and melon seedlings, showing a higher control efficacy than those of biofungicides during seedling stage. The treatment of water spray was not effective and showed a higher disease incidence than the untreated control plot in the oriental melon and melon seedlings. The curative application with environment friendly control agents, after powdery mildew was first detected, could not successfully controlled the disease at the middle stage (5~10% of disease incidence) of disease development. The curative combined application of [R. undulatum extracts (1st application) + wettable sulfur powder (2nd) + neem oil (3rd)] showed the highest control efficacy among the other treatments, with control value over 80% at the early stage (less than 1% of disease incidence) of disease development.

This study was executed in an attempt to investigate a artificial requisites of fruitbody occurrence. Environmental requirements on habitat for fruitbody occurrence of collected cultures resulted in leading to $13-16^{\circ}C$ and 75% relative humidity, and requiring silt loam of soil texture which had more nutritional substances than a dry field. Optimal temperature was $25^{\circ}C$, medium PDB, and pH 5.0 in cultural conditions. Mannose required of 5% in ASI 59002, 59003, 59004, but 3% in ASI 59001 was selected as optimum carbon source. The substrates stimulating sclerotium formation were cotton waste, or cotton waste + oak sawdust (mixture ratio of 8:2), which had 20% additive of wheat barn respectively. Sclerotium was formed well in the substrate adjusted chemical properties by applying 2% of calcium sulfate. Sclerotium formation was the most effective in the treatment of peat moss + oak sawdust (mixture ratio of 5:5) + 30% of wheat barn.

Quantitative HPLC analysis for the determination of in herbal liquid preparations was improved from the general test method besides the Korean Pharmacopeia. Good chromatographic separation of samples containing parabens, interferences, and other pharmaceutical excipients was effectively achieved by using acetonitrile water (containing 1% glacial acetic acid) mixture (30:70 v/v) as mobile phase. To monitor preservatives (benzoic acid, parabens, sorbic acid, dehydroacetic acid, and their salts) in herbal liquid preparations, a group of 47 samples was divided into two different group: preservative labeled group and unlabeled group. From the results, the contents of preservatives in 31 samples of preservative labeled group fell under KFDA regulations, and the contents of dehydroacetic acid in 6 samples of preservative labeled group were not followed by KFDA regulations. Preservatives were detected in 3 samples out of 10 samples in preservative unlabeled group.

The present study was aimed at preparing microemulsion-based hydrogel (MBH) for the skin delivery of itraconazole. Microemulsion prepared with Transcutol as a surfactant, benzyl alcohol as an oil and the mixture of ethanol and phasphatidyl choline (3:2) as a cosurfactant were characterized by solubility, phase diagram, particle size. MBHs were prepared using 0.7 % of xanthan gum (F1-1) or carbopol 940 (F1-2) as gelling agents and characterized by viscosity studies. The in vitro permeation data obtained by using the Franz diffusion cells and hairless mouse skin showed that the optimized microemulsion (F1) consisting of itraconazole (1% w/w), benzyl alcohol (10% w/w), Transcutol (10% w/w) and the mixture of ethanol and phospahtidylcholine (3:2) (10% w/w) and water (49% w/w) showed significant difference in the flux (${\sim}1{\mu}g/cm^2/h$) with their corresponding MBHs (0.25-0.64 ${\mu}g/cm^2/h$). However, the in vitro skin drug content showed no significant difference between F1 and F1-1, while F1-2 showed significantly low skin drug content. The effect of the amount of drug loading (0.02, 1 and 1.5% w/w) on the optimized MBH (F1-2) showed that the permeation and skin drug content increased with higher drug loading (1.5%). The in vivo study of the optimized MBH (F1-2 with1.5% w/w drug loading) showed that this formulation could be used as a potential topical formulation for itraconazole.

This experimental study was performed to investigate the antifungal effects of mixture of Sophorac Subprostratae Radix, Aconti Radix, and Hibisci Syriaci Cortex by the three types of extraction in the dermatophytes such as Trichophyton rubrum, Trichophyton mentagrophytes, and Epidermophyton floccosum. The following results were obtained by using Minimum Inhibition Concentration(MIC) and Inhibition Zone. 1. MIC on Trichophyton mentagrophytes in Sample S-2, Sample S-3, and Sample-Y were 10${\mu}l$, respectively, showing the highest antifungal effect. 2. MIC on Epidermophyton floccosum in Sample S-2, Sample S-3, and Sample-Y were 10㎕ respectively, showing the highest antifungal effect. 3. MIC on Trichophyton rubrum in Sample S-3, Sample-Y were 10${\mu}l$ respectively, showing the highest antifungal effect. 4. The size of inhibition zone on Trichophyton mentagrophytes for Sample S-3 were 22.3mm in 10${\mu}l$, showing the highest antifungal effect. 5. The size of inhibition zone on Epidermophyton floccosum for Sample S-3 was 34.3mm in 10${\mu}l$, showing the highest antifungal effect. 6. The size of inhibition zone on Trichophyton rubrum for Sample-Y was 26.5mm in 10${\mu}l$, showing the highest antifungal effect. Whereas. in extractions, that of Sample S-3 was 12.5mm in 10${\mu}l$, showing the highest antifungal effect. 7. From the above results, Sample S-3 on Trichophyton mentagrophytes, Epidermophyton floccosum and Sample-Y on Trichophyton rubrum showed the highest antifungal effects. This results suggests that vinegar extraction excels other extraction method using water or ethanol to measure the antifungal effect on dermatophytes. In addition, the result shows that the extract of herbal medicines can be used to tinea pedis and if further study is performed, the use of the extract of herbal medicines will be valuable and beneficial in the clinical medicines.
