  • 목적 : 상지, 상백피, 상엽은 모두 뽕나무에서 유래한 것으로 한의학에서 수천 년 동안 사용되어왔다. 최근 이들의 미백효능이 발견되면서 더욱 주목을 받고 있다. 피부의 멜라닌 색소 침착은 자선에 대한 정상적인 방어기전이다. 그러나 비정상적인 색소침착은 심각한 미용적 문제를 가져온다. 최근 약침이 피부 미백에 이용되고 있다. 또한 발효와 열처리는 미백화장료 가공의 최신 경향이다. 이 연구에서는 상지, 상백피, 상엽 약침액이 발효와 열처리 후에 피부 미백에 어떠한 영향을 미치는지 알아보고자 한다. 방법 : 상지, 상백피, 상엽을 각각 4개의 그룹으로 나누었다. (1) 비발효, 비열처리, (2) 비발효, 열처리, (3) 발효, 비열처리, (4) 발효, 열처리한 그룹들에 타이로시나제 활성 및 도파 산화 활성, 그리고 멜라닌 함량을 측정하여 비교하였다. 결과 : 타이로시나제 활성 및 도파 산화 활성, 그리고 멜라닌 함량에 있어서, 발효, 열처리가 대체로 효과가 있는 것으로 나타났다. 특히 멜라닌 함량에 있어서 발효, 열처리한 군이 대조군에 비해 유의성 있는 감소를 보였다. 결론 : 주근깨, 흑색종, 간반(肝斑) 등 비정상적인 색소 침착 질환을 치료하기 위한 상지, 상백피, 상엽 약침액 제조에 있어, 발효 및 열처리 방식을 적용하면 보다 나은 미백효능을 발휘할 수 있을 것으로 생각된다.

  • 목적 : Acetylcholine은 콜린과 아세트산의 에스테르로 인체에서 중요한 신경전달물질로 Acetylcholine-sterase(AChE)라는 효소에 의해 분해된다. Alzheimer's disease, ataxia, myasthenia gravis, Parkinson' disease 등의 질환에 AChE 억제제가 사용되어 왔으며 최근 한약재의 AChE 억제 효능에 관한 연구들도 진행되고 있다. 봉독은 관절염, 통풍 등의 질환에 응용되어 왔으며 진통효과 및 항염증작용에 대한 임상적, 실험적 연구가 많이 보고되어 왔으나 AChE 억제효과에 대한 연구는 아직까지 보고된 바 없다, 본 연구에서는 봉독약침액과 봉독의 과민반응 유발항원 중 하나인 Phospholipase A2 억제효능이 있는 것으로 알려진 상백피를 혼합한 상백피봉독약침액의 AChE 억제효과를 알아보았다. 방법 : PC12 세포주에서 추출한 AChE와 0.1, 0.01 and $0.001mg/m{\ell}$ 농도의 봉독약침액 및 상백피봉독약침액을 60분간 반응시켰다. 효소면역측정법(ELISA)을 이용하여 흡광도를 10분, 30분, 60분 경과시 각각 측정한 후 효소활성저해도(%)를 계산하였다. 효소활성저해도(%) = [(Cc - Ce)/Cc] ${\times}$ 100 Cc : 대조군 흡광도, Ce : 실험군 흡광도 결과 : 1. 봉독약침액은 0.1, 0.01, $0.001m{\ell}/mg$의 농도에서 30분 경과 후부터 유의성 있는 억제효과를 나타내었다. 2. 상백피봉독약침액은 $0.1m{\ell}/mg$ 농도에서 10분 경과 후부터 유의성 있는 억제효과를 나타내었고, $0.01m{\ell}/mg$ 농도에서 30분경과 시 유의성 있는 억제효과를 나타내었다. 3. 봉독약침액과 상백피봉독약침액의 AChE 억제효과 비교에서 봉독약침액의 억제효과가 상백피봉독약침액 보다 뛰어났다. 요약 : 봉독약침액과 상백피봉독약침액의 AChE 억제효과를 확인하여 두 군 모두 유의성 있는 결과를 얻을 수 있었다. 앞으로 알츠하이머병이나 치매와 같은 신경퇴행성 질환에 대한 봉독의 임상적 활용 및 보다 넓은 범위에 대한 연구가 필요할 것이라 사료된다.

  • The aim of this study was to compare the anti-inflammatory effects of ethanol extracts of root peel and spear of mulberry (RME and SME, respectively) in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. Both extracts significantly inhibited the production of reactive oxygen species (ROS), nitric oxide (NO), and interleukin-6 (IL-6). However, prostaglandin $E_2$ ($PGE_2$) levels decreased in LPS-stimulated RAW 264.7 cells treated with SME. Additionally, the extracts reduced inducible NO synthase (iNOS) expression and cyclooxygenase-2 (COX-2) in mRNA levels. Although ROS production was lower in the RME-treated cells than in the SME-treated cells, the levels of other inflammatory parameters, including IL-6 and $PGE_2$, and mRNA levels of iNOS and COX-2 reduced more in the SME-treated cells. These results indicate that SME showed higher anti-inflammatory activities than RME. Therefore, SME can be used as a functional food ingredient to enhance health.

  • This study evaluated the neuroprotective effect of extracts from the root bark of Morus alba (MA) against glutamate-induced cytotoxicity in neuronal cells. Glutamate-induced cytotoxicity was shown by MTT reduction assay. The neuroprotective effects of methanol, ethanol, and acetone extracts from MA against glutamate-induced cytotoxicity were measured. Among the three extracts, the methanolic extracts showed the highest protective effect, as determined by the results of an morphological assay, a lactate dehydrogenase release assay. Furthermore, the methanol extracts were fractionated sequentially with hexane, diethyl ether, ethyl acetate, and water layer according to degree of polarity. The hexane fractions exhibited a neuroprotective effect against glutamate-stressed N18-RE-105 cells. Therefore, these results suggest that extracts of MA could be a new potential candidate as a protective substance against glutamate-induced cytotoxicity.

  • The ethanol extract of root bark of Morus alba strongly inhibited the Gram positive bacteria like Streptococcus sp., Lactococcus garvieae and Staphylococcus sp., but weakly the Gram negative bacteria like Listonella anguillarm and Edwardsiella tarda. It was more effective in liquid medium than in solid medium. The minimum inhibition concentration (MIC) of the extract in liquid medium was 19.8 and 790~1185 $\mu\textrm{g}$/$m\ell$ for the Gram positive and Gram negative bacteria, respectively. The extract concentration, at which the growth was totally inhibited, was 67.2~403.0 $\mu\textrm{g}$/$m\ell$ for the Gram positive bacteria but it was as high as 1185 $\mu\textrm{g}$/$m\ell$ for L. anguillarum and almost ineffective against E. tarda. For diet supplementation of the extract, effective soaking duration was 3 minutes. The fish diet soaked in the extract inhibited the growth of all the tested Gram positive strains, but not the Gram negative strains. The relationship between the weight of fish diet and absorption of the extract by the fish diet was Y=7.5757X + 4.6962($R^2$ = 0.9998).

  • Purpose: Our previous study demonstrated the hypoglycemic effects of mulberry (Morus alba L.) leaf and the underlying mechanisms. Here we explored the potency of mulberry twigs (TW) and root barks (RB) in postprandial hypoglycemic effects in vitro and in vivo. Methods: The major components of TW and RB were determined by high performance liquid chromatography (HPLC). Alpha-glucosidase inhibition and glucose/fructose uptake inhibition in Caco-2 cells were determined for TW, RB, and their major components, followed by an oral sugar tolerance test (OSTT) in streptozotocin-induced diabetic rats. Male Wistar rats were fed a high-fat diet for 2 weeks and then a single dose of streptozotocin (35 mg/kg B.W) was administered by intraperitoneal injection. Rats with fasting blood glucose levels above 126 mg/dL were randomly divided into 5 groups (n = 8/group) for the following treatments by gavage for 4 weeks: vehicle (normal control and diabetic control), 200 mg/kg B.W of TW or RB or 100 mg/kg B.W of oxyresveratrol (OXY). Results: OXY and mulberroside A were identified as the major components of TW and OXY, mongolicin, and kuwanon H for RB. A significant inhibitory activity on ${\alpha}-glucosidase$ was found for TW, RB, and OXY (p = 0.0099). There was a dose-dependent inhibition of TW and RB on the intestinal sugar uptakes in Caco-2 cells, showing a greater impact on fructose compared to glucose. The OSTT showed that TW and RB significantly delayed time to maximal concentration (p = 0.0088) and decreased maximal concentration (p = 0.0043) compared to the control group. Conclusion: These results suggest that TW and RB may have a postprandial hypoglycemic effect, particularly in the case of high fructose or sucrose intake. OXY was suggested as a contributor to the hypoglycemic effect of TW and RB. Further studies are needed for the systemic effect of TW and RB in circulation.

  • This study was to examine the shelf life and qualities of castellas added with mixture of Morus alba root bark (MA), Ecklonia stolonifera (ES), and Curcuma aromatica (CA) extracts (MECE). The result of total microbial cell count showed that castellas with MECE were increasing storage time, especially at the rate of MA : ES : CA=0.75:0.75:0.5, and was reduced about 3 log cycle as compared to that of control. Also castellas with MECE were shown to have the highest antioxidant effect by Rancimat method. In the color, redness of castellas diminished with increasing amounts of MECE in castellas while conversely, lightness and yellowness increased. In sensory evaluation, the castella containing MA 0.25%, ES 0.25% and CA 0.125% were preferred than the control. These results suggest that the addition of MA 0.25%, ES 0.25% and CA 0.125% in castella positively improved the preservation and development of quality.

  • This study was performed to examine the shelf life and qualities of wet noodle with Morus alba L. root and Curcuma aromatica extracts (MCE) during storage at $4^{\circ}C$. Lightness and redness of wet noodle were decreased with increasing amounts of MCE added in noodle while yellowness was increased. The viable cell and molds count of wet noodle with MCE was reduced about 1~2 log cycle as compared with control during storage time. Also the TBARS (thiobarbituric acid reactive substance) value of wet noodle with MCE was lower than that of control. Hence the wet noodle with MCE has shown remarkable antioxidation effect. In sensory evaluation, the wet noodle containing the ratio of 2.5:0.02 of M. alba : C. aromatica was preferred than the control. From these results, the addition of 2.5% of M. alba and 0.02% of C. aromatica extracts in wet noodle had a good effect on improvement of preservation and development of quality.
