Objectives : The purpose of this study is to determine whether Rhus verniciflua Stokes with Latin name Lacca Sinica Exsiccata, and Eucommia ulmoides Oliver with Latin name Eucommiae Cortex Extract Combination (ILF-RE) improves laboratory test results in participants with liver function disorder. Methods : This study was conducted at Woosuk university Korean medicine hospital where participants with high serum alanine transaminase (ALT) levels from 45 to 135 U/L were enrolled. Subjects received ILF-RE 3.6 g (1.2 g/day as ILF-RE) or placebo 3.6 g for 12 weeks. It was confirmed that urushiol was not detected in ILF-RE. The primary outcomes were the decrement degree of serum ALT and gamma-glutamyl transferase (GGT) levels between two groups. The secondary outcomes were the decrement degree of serum aspartate transaminase (AST), alkaline phosphatase (ALP), lactate dehydrogenase (LD), total bilirubin, total cholesterol, triglyceride (TG) and fatty liver index (FLI) levels between two groups. Adverse events, skin prick tests, laboratory tests, and vital signs were observed and analyzed to confirm the safety of ILF-RE.1) Results : In the ILF-RE group, the liver function index ALT, GGT, lipid metabolism index TG, and fatty liver index FLI were significantly decreased compared to the placebo group. There was no significant difference in ILF-RE group in terms of adverse events, severe adverse events, skin prick test, laboratory test, and vital signs compared with placebo group. Conclusions : ILF-RE was found to be effective in improving liver function. In addition, no clinically significant adverse events or body changes were observed during this study.

In this study, we have investigated the HPLC analysis methods and quantitative analysis of standard compounds for quality standardization of a medicinal crude drug GCSB-5, a herbal formulation consisting of 6 medicinal plants (Acanthopanacis Cortex, Achyranthis Radix, Ledebouriellae Radix, Cibotii Rhizoma, Glycine Semen, Eucommiae Cortex) which are used in traditional medicine to treat various bone disorders. HPLC analysis methods of acanthoside D(Acanthopanacis Cortex), 20-hydroxyecdysone(Achyranthis Radix) which were known standard compounds among 6 medicinal plants were developed on crude material and product. And validation of HPLC analysis methods were conformed for verification of HPLC methods by check to specificity, linearity, intra-day precision, inter-day precision and accuracy following ICH guideline. Content of acanthoside D and 20-hydroxyecdysone on raw material of GCSB-5 were decided at 0.577-0.578 mg/g and 0.311-0.312 mg/g. And we confirmed that content of acanthoside D and 20-hydroxyecdysone on GCSB-5 preparation were 0.302-0.303 mg/capsule and 0.113-0.115 mg/capsule.

최근 미세먼지, 내분비장애, 환경 호르몬등에 의해 피부 염증 질환 환자들이 증가함에 따라 화장품 소재 개발 연구는 스테로이드, 항히스타민제 등의 피부염 치료 합성화합물 보다 이를 대체할 수 있는 천연물 기반의 보다 안전한 소재 발굴에 관심이 더 증가되고 있다. 따라서 본 연구에서는 여러 가지 천연 약재 스크리닝을 거쳐 피부 효능 효과가 검증된 두충, 익지인, 백강잠의 한방추출물(Mix)을 선정하고, 이들의 새로운 피부효능을 규명하여 천연 화장품 소재를 개발하고자 하였다. 우선 한방추출물(Mix)의 항산화 효능을 검증하기 위해 DPPH assay를 수행한 결과 $400{\mu}g/mL$ 농도 조건에서 약 98.8% DPPH radical 소거 활성을 확인하였다. 한방추출물(Mix)의 미백효능을 확인하기 위해 B16F10 세포주를 활용하여 한방추출물에 의한 멜라닌 합성량을 측정하였다. $400{\mu}g/mL$ 농도 조건에서 ${\alpha}-MSH$ 처리군 대비 27.1% 수준까지 멜라닌 합성량이 감소하여 미백효능 활성에 대해 유의성 있는 결과를 확인하였다. 또한 한방추출물(Mix)의 항염증 효능을 확인하기 위해 LPS 자극으로 활성화된 RAW264.7 대식세포에서 NO(nitric oxide) 합성 및 iNOS, COX-2의 유전자 발현을 관찰한 결과 모두 유의적으로 감소되는 것을 확인하였다. 염증성 사이토카인으로 알려진 $IL-1{\alpha}$, $IL-1{\beta}$, IL-6, $TNF-{\alpha}$의 mRNA 발현을 분석한 결과에서도 한방추출물에 의해 효과적으로 억제되는 것을 확인하였다. 마지막으로 피부장벽 기능 강화를 확인하기 위해 인간 각질형성세포인 HaCaT을 이용해 tight junction 구성 단백질인 claudin 1 유전자의 발현 변화를 관찰한 결과 한방추출물에 의해 mRNA 발현이 농도 의존적으로 증가되는 것을 확인하였다. 따라서 본 연구를 통해 우리는 두충, 익지인, 백강잠을 함유한 한방추출물(Mix)이 항산화, 항염, 미백, 그리고 피부장벽 강화 등에 유효한 소재임을 확인하였고, 향후 피부 임상시험 등이 이뤄진다면 피부염 환자에 효과적인 천연 화장품 소재로 개발될 수 있을 것이다.

This study examined the antinociceptive properties of GCSB-5, a herbal formulation consisting of 6 Oriental herbs (Ledebouriellae Radix, Achyranthis Radix, Acanthopanacis Cortex, Cibotii Rhizoma, Glycine Semen, and Eucommiae Cortex) that are used in traditional medicine to treat various bone disorders, mainly of which involve analgesic processes. Peripheral and central analgesic models were established in experimental animals in order to evaluate the antinociceptive effects of the agent. GCSB-5 significantly inhibited the number of acetic-induced writhing (33.3%-34.3% inhibition at 100-600 mg/kg) but increased the pain threshold (38.0% increase at 300 mg/kg) in the Randall-Selitto test. However, GCSB-5 had no effect on the hot plate-induced nociception and hyperalgesia from the tail-pinch method. These results suggest that the antinociceptive effect of GCSB-5 may be mediated via peripheral mechanisms.

Effects of twenty-three aqueous herbal extracts used in oriental medicines on heme oxygenase (HO)-1 expression were estimated in a mouse hippocampal cell line, HT22. HO-1 is one of the cytoprotective enzymes activated various stimuli, and Western blot analysis was used for evaluated HO-1 expression. Six aqueous extracts such as Rhei Rhizoma, Paeoniae Radix, Uncariae Ramulus et Uncus, Theae Folium, Prunellae Spica, and Coptidis Rhizoma significantly increased HO-1 expression in HT22 cells at the concentration of 300 ${\mu}$g/ml. In Addition, four aqueous extracts including Eucommiae Cortex, Moutan Cortex Radicis, Ginseng Radix Rubra, and Scutellariae Radix moderately increased HO-1 expression. These results would be usefulfor the isolation and identification of their neuroprotective principles.

The general pharmacological properties of GCSB-5, a herbal formulation consisting of 6 Oriental herbs(Ledebouriellae Radix, Achyranthis Radix, Acanthopanacis Cortex, Cibotii Rhizoma, Glycine Semen and Eucommiae Cortex), were investigated in mice, rats, guinea pigs and rabbits. The administration of GCSB-5 had no effect on general behavior, and did not influence the central nervous system. Mean blood pressure, heat1 and respiratory rate and contractile response of the isolated guinea pig atrium were unaffected by the treatment of GCSB-5. Addition of GCSB-5 did not cause spontaneous relaxation and contraction of the isolated guinea pig ileum and rat uterus. And also, GCSB-5 had no effect on the gastrointestinal system and the blood system of the animals examined in this study. GCSB-5, at higher doses(1,000 and 3,000 mg/kg), increased the urinary excretion of electrolytes, however, the urine volume and pH in rats were unaffected. Taken together, these results indicate that GCSB-5 does not induce any adverse effects in experimental animals and is expected to have no significant general pharmacological activities.
