Objectives : This study was carried out to investigate the anti-toxicity effect of Hwangryunhaedoktang on the dried Mylabris phalerata extract containing cantharidin in ICR mouse. Methods : Dried Mylabris phalerata extracts were orally administered at dosage level 2000, 1000, 500, 250 and 125mg/kg, respectively with and/or without administration of Hwangryunhaedoktang 200mg/kg. During 2 weeks, the changes of body weight, mortality, $LD_{50}$, macroscopic changes of gastrointestinal tract and liver, changes of serum gastrin and somatostatin levels were observed. Results : Decrease of body weight gains was observed in dried Mylabris phalerata extract-dosing groups, but it was significantly developed in Hwangryunhaedoktang extract-dosing groups after dosaging. Increase of mortality rates was observed in dried Mylabris phalerata extract-dosing groups, but it was significantly developed in Hwangryunhaedoktang extract-dosing groups after dosaging. The $LD_{50}$ of dried Mylabris phalerata extract in male mice significantly increased in a case of concomitant used of Hwangryunhaedoktang 268.86 vs 662.05mg/kg. Clinical signs were observed in dried Mylabris phalerata extract-dosing groups, but it was significantly developed in Hwangryunhaedoktang extract-dosing groups after dosaging after dosaging. Increase of number of hemorrhagic and/or erythematous spots in the gastrointestinal tracts, enlargement and congestion in the liver were observed in dried Mylabris phalerata extract-dosing groups, but it was significantly developed in Hwangryunhaedoktang extract-dosing groups after dosaging. Increase of serum gastrin level was observed in dried Mylarbis phalerata extract-dosing groups, these state of abnormal increase was significantly developed in Hwangryunhaedoktang extract-dosing groups after dosaging. Decrease of serum somatostatin level was observed in dried Mylabris phalerata extract-dosing groups, these state of abnormal decrease was significantly developed in Hwangryunhaedoktang extract-dosing groups after dosaging. Conclusions : We could conclude that the Hwangryunhaedoktang has anti-toxicity effect on the dried Mylabris phalerata extract containing cantharidin.

Objective : This experimental study was performed to investigate the effect of Hwangryunhaedoktang Herbal-acupuncture & extract on Staphylococcus aureus and Staphylococcus epidermidis that induce keratitis. Methods : MIC was measured by dropping to $50{\beta}^{\circ}$ according to density Hwangryunhaedoktang Herbal-acupuncture & extract(100%, 10%, 1%, 0.1%). Anti-bacterial potency was measured by the size of inhibition zone With change of volume. Results : 1. MIC on Staphylococcus aureus in Hwangryunhaedoktang Herbal-acupuncture & extract were not disappear all sample. 2. MIC on Staphylococcus epidermidis in Hwangryunhaedoktang Herbal-acupuncture & extract were not disappear all sample. Conclusions : The present author think that Hwangryunhaedoktang Herbal-acupuncture must be extract a new method for anti-bacterial potency.

Objectives The purpose of this study is to report the effect of Korean medical treatment on an infant with burn injury. Methods We treated the infant suffering from burn injury by Korean medical treatment such as acupuncture, Hwangryunhaedoktang extract, Jaungo dressing from March 15th, 2016 to March 26th, 2016. This efficacy of treatment was evaluated with observation. Results After this treatment, burn wound size was reduced and skin tissue regeneration was accelerated. As time passes, pigmentation was faded. Conclusions This case report showed that the Korean medical treatment is effective in the treatment of pediatric burn. However further case studies are still required to confirm these findings.

Hwangryunhaedoktang (HHT) has been traditionally used as a preventive and therapeutic medicine to treat enervation and diverse chronic diseases. This study was designed to compare the antioxidant, anti-wrinkle and whitening effects of HHT extract and its fermented extract by Leuconostoc mesenteroides (FHHT). FHHT was prepared by inoculation of L. mesenteroides after the extraction procedure with 70% ethanol. HHT and FHHT was investigated via high-performance liquid chromatography (HPLC). Simultaneous qualitative analysis of two bioacitive components, berberine and palmatine. was achieved by comparing their retention times ($t_R$) and UV spectra with those of the standard components. Cell viability test results indicated that both HHT and FHHT were non-toxic. In DPPH radical scavenging ability, $SC_{50}$ values of the FHHT was $68.85{\mu}g/mL$, which is more effective than HHT. Moreover, FHHT showed higher expression in production of procollagen type I than HHT. In nontoxic concentration range, FHHT showed strong melanin production inhibitory effect in ${\alpha}-melanocyte$ stimulating hormone (${\alpha}-MSH$)-stimulated B16F10 cell ($IC_{50}=9.82{\mu}g/mL$). These results suggested that fermented extracts of hwangryunhaedoktang had considerable potential as a cosmetics ingredient with an antioxidant and anti-wrinkle and whitening effects.

Objectives : The present study was designed to investigate effects of mixed extracts (9:1, v/v) of Hwangryunhaedoktang, Chamaecyparis obtusa essential oil. We evaluated the antimicrobial and antioxidant activity by manufacturing mixed extracts as the materials for functional medicinal herb cosmetics. Methods : We performed antimicrobial were tested microbes (Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli, Candida albicans, Propionibacterium acnes) by disc diffusion method and measure clear zone. Antioxidant activities were measured by DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity. Results : Antimicrobial activities of mixed extracts against S. epidermideis, P. acnes, S. aureus, E. coli, and Candida. A were $10.9{\pm}3.0mm$, $16.9{\pm}2.0mm$, $9.2{\pm}2.0mm$, $10.3{\pm}1.0mm$, $11.8{\pm}3.0mm$ respectively. The Chamaecyparis obtusa essential oil had the highest antimicrobial activities against S. epidermideis, P. acnes, S. aureus, E. coli, and Candia. A and clear zone of microbes ware $16.7{\pm}3.0mm$, $28.8{\pm}0.2mm$, $15.9{\pm}2.0mm$, $11.5{\pm}1.0mm$, $16.3{\pm}3.0mm$. Hwangryunhaedoktang extract showed antimicrobial activity but only P. acnes and S. aureus The antioxidant activities of the mixed extracts were tested through the evaluation of DPPH radical scavenging activity. The 100 % mixed extracts were found to have 90 % DPPH radical scavenging activity. The mixed extracts was presented similar antioxidant activities compared with that of ascorbic acid. As a result, A mixture extract is expected to have antimicrobial effects and free radical scavenging activity was found. Conclusions : Accordingly, It can be concluded that mixed extracts has the potential to cosmetic material.
