본 연구는 운지버섯 자실체의 열수추출물(HE)과 메탄올 추출물(ME)의 총 polyphenol과 flavonoid 함량과 일부 생리활성을 2015년 3월부터 2016년 2월에 조사하였다. 자료 분석은 SPSS 2.0을 이용하였다. 연구결과는 HE의 총 polyphenol 함량(129.60 mg/dl)은 ME함량(43.80 mg/dl)보다 85,8 mg/dl가 더 높았으며, 열수에서 추출이 더 높았다. HE의 총 flavonoid 함량(30.50 mg/dl)은 ME함량(20.90 mg/dl)보다 9.5 mg/dl가 더 높았다. DPPH의소거활성은 HE 1 mg/ml에 비해서 3 mg/ml에서는 41.03%가, ME 1 mg/ml에 비해서 3 mg/ml에서는 16.36%로 더 높았으며, Tyrosinase저해활성은 HE 1 mg/ml에 비해서 3 mg/ml에서는 8.29%, ME 3 mg/ml에서는 10.32%가 더 높았고, Elastase 저해활성은 HE 1 mg/ml에 비해서 3 mg/ml에서는 3.12%가, ME에서는 21.53%가 더 높았다. Collagenase저해활성은 HE 1 mg/ml에 비해서 3 mg/ml에서는 5.44%가, ME에서는 4.07%로 더 높았다. 상기 효소활성은 모두 추출액농도증가에 비례하여 활성이 증가하였다. 결론적으로 상기의 두 종류의 추출물은 항산화 및 생리활성기능을 나타내어 피부의 주름의 완화제로서 유용하다고 판단되었다.

Objects : The purpose of this study was to observe the effect of Salviae Miltriorrhiza Radix(SMR) water-extract on intracerebral hemorrhage(ICH) and neuronal apoptosis in the injured areas. Method : ICH was induced by the stereotaxic intrastriatal injection of bacterial collagenase type IV in Sprague-Dawley rats. The rats were givened oral SMR treatment once a day for three days after the ICH treatment. TUNEL positive cells in the affected regions were performed by TUNEL assay, Bax and Bcl-2 positive cells by immunohistochemistry and the Bax expression by western blotting method. Results : The results are as follow; 1. SMR significantly reduced the number of TUNEL positive cells in the peri-hematoma reigions of ICH-induced rats. 2. SMR significantly reduced the number of Bax positive cells in the peri-hematoma regions of ICH-induced rats. 3. SMR did not affect the number of Bcl-2 positive cells in the peri-hematoma regions of ICH-induced rats. 4. SMR significantly reduced the Bax expressions compared with ICH group in hemorrhagic hemisphere of ICH-induced rats. Conclusion : These results suggest that SMR is effective in reducing neuronal apoptosis.

Styela plicata are naturally-occurring marine resources easily found along the coastlines that have established their niche as functional food and nutraceuticals ingredient along with their increasing consumer demand. Ascidian contain a large amount of dietary fiber but only the meat has been utilized and consumed while the rest of its parts are discarded. Also, various studies have been conducted on the meat of ascidians while studies on the functionality of the ascidian tunics, which were mostly undervalued, were scarce. In this study, we investigated and explored the glycosaminoglycans (GAGs) contents in the tunics of S. plicata, and their potential use as functional ingredient in pharmaceutical and nutraceutical applications. Sulfated GAGs and uronic acids contents were 8.9-10.7 g/100 g and 9.4-11.3 g/100 g, respectively. Highest GAGs content was extracted with optimum Brix at 7-9. Extraction efficiency using hot water at 121℃ was 4.22% while enzyme extraction using Protamex was more efficient at 5.91%. GAGs extracted from S. plicata tunics exhibited collagenase inhibitory activity of 75.2% at 100 ㎍/mL and procollagen synthesis activity of 80.1% at 100 ㎍/mL.

목적 : 본 연구는 화피의 연골 보호 및 소염 진통 작용을 알아보고, 화피를 이용한 관절염치료 약침액 개발의 기초자료를 얻기 위해 고안되었다. 방법 : In vitro에서는 토끼 무릎관절에서 배양된 연골조직에 5ng/ml IL-1${\alpha}$ 처리 후， 화피의 연골보호 효과, 연골세포에 대한 독성을 조사하였다. In vivo에서는 토끼 무릎관절내 collagenase를 주입, CIA 유발 후, 28일간 매일 토끼의 구강으로 화피, 증류수, CEX를 투여하였으며, 연골보호, 소염, 진통에 대한 측정을 하였다. 결과 : 화피는 proteoglican 및 collagen분해 억제, MMPs 활성 억제로 연골 보호 효과가 있었으며, 연골 세포에 대한 독성이 없었다. 소염작용은 PGE2 생산 억제 및 COX-2발현 억제, carrageenan 유발 쥐 모델에서의 부종 억제로 확인되었다. 진통작용은 tail flick test에서의 latency time 증가, formalin test에서의 염증성 통증억제로 나타났다. 결론 : 화피가 퇴행성관절염에 대한 연골 보호 효과 및 소염 진통 작용이 있으므로, 이를 근거로 약침액을 개발 응용하면 퇴행성관절염 치료에 활용될 수 있다고 사료된다.

Background: Green tea contains numerous polyphenols, which have health-promoting effects. The purpose of this study was to evaluate the effect of tannase-converted green tea extract (TGE) formulation on the physical stability and activities of skin-related enzymes. Methods: Physical stability was evaluated by measuring the pH, precipitation, and colors at $25{\pm}2^{\circ}C$ /ambient humidity and at $40{\pm}2^{\circ}C$ \70%${\pm}$5% relative humidity for 4 months. Activities of collagenase, elastase, and tyrosinase as skin-related enzymes were assessed on TGE formulation. Results: The concentrations of epigallocatechin-3-gallate and epicatechin-3-gallate in green tea extract were greatly decreased to the extent of negligible level when treated with tannase. The formulation containing 5% tannase-converted green tea extract showed relatively stable pH, precipitation, and color features for 16 weeks. When TGE was added to the formulation, there was a significant increase in the inhibition of elastase and tyrosinase activities (p<0.05) compared with the formulation containing 5% normal green tea extract. Conclusion: The TGE could be used in cosmetics as skin antiwrinkling or depigmenting agent.

We evaluated the antioxidant activity and anti-wrinkle effects of Aceriphyllum rossii leaf ethanol extract (ARLEE) in vitro using human dermal fibroblasts. The total polyphenol and flavonoid contents of ARLEE were 578.6 and 206.3 mg/g, respectively. At a concentration of $250{\mu}g/mL$, the electron-donating ability of ARLEE was 87.1%. In comparison with the vehicle, ARLEE treatment at $100{\mu}g/mL$ significantly increased type I procollagen synthesis (p < 0.01) by 50.7%. In vitro ARLEE treatment (10 mg/mL) inhibited collagenase and elastase activity by 97.1% and 99.2%, respectively. Compared with the control, ascorbic acid treatment at $100{\mu}g/mL$ significantly decreased matrix metalloproteinase (MMP)-1 protein expression (p < 0.01) by 37.0%. ARLEE treatment at $50{\mu}g/mL$ significantly decreased MMP-1 protein expression (p < 0.01) by 46.1%. Ascorbic acid and ARLEE treatments at $100{\mu}g/mL$ significantly decreased MMP-1 mRNA expression (p < 0.01) by 26.1% and 36.1%, respectively. From these results, we conclude that ARLEE has excellent antioxidant activity and even better anti-wrinkle effects than ascorbic acid in human dermal fibroblasts. These results suggest that ARLEE could be used in functional cosmetics for the prevention or alleviation of skin wrinkles induced by ultraviolet rays.
