The inhibitory activity of several crude drugs on $\alpha$-glucosidases, which are the key enzymes for carbohydrate digestion and the prevention of diabetic complications, was investigated. Several crude drugs including Terminaliae Fructus, Mori Cortex Radicis, Caesalpiniae Lignum and Cyrophora esculenta potently inhibited maltase and sucrase isolated from rat intestine, while Arecae Semen and Corni Fructus remarkably inhibited $\alpha$-amylase. Caesalpiniae Lignum and Gyrophora esculenta exhibited significant reductions of blood glucose elevation in mice loaded with maltose and sucrose.

The immunomodulating activity of a polysaccharide isolated from Morus alba (PMA) root bark was examined in murine splenic lymphocytes. PMA enhanced proliferation of splenic lymphocytes in a synergistic manner in the presence of mitogens. However, PMA suppressed pri-may IgM antibody production from B cells, which was activated with lipopolysaccharide, a polyclonal activator, or immunized with a T-cell dependent antigen sheep red blood cells. Our observations showed that the immunomodulating activity of PMA increased lymphocyte proliferation and that PMA decreased antibody production from B cells, which was distinct from those of other plant-originated polysaccharides.

Yersinia enterocolitica, which causes yersiniosis, is a bacterium that produces biofilms effectively. The inhibition of biofilm formation provides a method for preventing infections with Y. enterocolitica. In this study, the inhibitory activity of Y. enterocolitica biofilm formation was investigated in a library of 140 edible plant methanol extracts including forest products. It was identified that the biofilm formation could be inhibited by 12 extracts of plants, Agastachis Herba, Agrimoniae Herba, Diospyros kaki leaves, Elsholtziae Herba, Ginkgonis Semen, Lycopi Herba, Melonis Pedicellus, Menthae Herba, Mori Radicis Cortex, Polygoni Multiflori Radix, Prunellae Spica, and Schizonepetae Spica. After changing the solvent to ethanol and water, the greatest inhibition of biofilm formation was produced by a 50% ethanol extract of Polygoni Multiflori Radix. A method to effectively prevent yersiniosis can be developed using the edible plant extracts identified in this study.

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.

Currently, cancer is the primary cause of death and 50% of cancer patients are incurable by surgery, radiotherapy and chemotherapy. Therefore, immunotherpy is interested as the fourth remedy. Biological response modifier (BRM), such as organometallic compounds, glycoproteins, polysaccharides and other natural products. Is the one which can enhance the immune response against cancer cell. To develop new BRM from natural sources, we investigated 63 species Korean traditional medicines by observing the mitogenic activity to splenocytes, generation of activated killer cells and activation of macrophages. Finally, we selected 9 species including Angelicae gigantis Radix, Mori Cortex Radicis, Arisaematis Tuber, Salviae Radix, Cnidii Rhizoma, Ligusti Fructus, Pasoraliae Semen, Loranthi Ramulus, Ginseng Radix. Bioassay-guided fractionation and purification is undergoing.

The hair cycle consists of three phases, growth (anagen), involution (catagen) and quiescence (telogen) phases. In order to evaluate hair re-growth effect of herbal extracts mixture containing the 70％ ethanol extracts of Polygoni Multiflori Radix, Mori Cortex Radicis, Gingko Biloba Folium and Pine bud, we have examined the induction of the anagen phase and/or elongation of the anagen period using C3H mice. Morphological examination was done by Hattori' and Ogawa's method. Enzyme activities of ${\gamma}$-glutamyl transpeptidase (${\gamma}$-GT) and alkaline phosphatase (ALP) was detected by Bessey-Lovry-Brock's method. Enzyme activity as a biochemical marker of hair cycle was investigated in the third hair cycle period of C3H mice after depilation. 3％ Minoxidil treated group and herbal extract mixture treated group were shown 3 days earlier initiation of anagen than control group. In cycling mouse skin, ${\gamma}$-GT activity is pronounced during anagen and greatly diminished during telogen. Herbal extract mixture has shown promising hair re-growth effect on hair follicular cycles of C3H mice.

Leukotriene $B_4\;(LTB_4)$ is a pro-inflammatory mediator synthesized in myeloid cells from arachidonic acid. Elevated levels of $LTB_4$ have been found in a number of inflammatory diseases and levels are related to disease activity in some of these. Because $LTB_4$ interacts with cells through specific cell surface receptors, $LTB_4$ receptor blockade is the most specific approach to reduce the pathogenic role of $LTB_4$. In order to find $LTB_4$ receptor antagonist from plants, we screened the $LTB_4$ receptor antagonistic activity of the methanol extract and solvent fractions of herbal drugs. The ability of samples to inhibit specific binding of $[^3H]-LTB_4$ to human peripheral neutrophils was used as assay to evaluate the antagonistic activity of plant materials. Among the tested methanol extracts of herbal drugs, Mori Radicis Cortex, Perillae Semen, Armeniacae Semen and Sophorae subprostratae Radix showed potent inhibitory activity above 70% at the concentration of $100\;{mu}g/ml$. The inhibitory activities of $LTB_4$ binding to human neutrophils were evaluated for several solvent fractions at three different concentrations. Especially, hexane soluble fractions of Anemarrhenae Rhizoma and Embeliae Radix, and ethyl acetate soluble fractions of Aristolochiae Fructus, Magnoliae Cortex and Zingiberis Rhizoma crudus showed moderate activity at $25\;{mu}g/ml$. These fractions were promising candidates for the study of the activity-guided chromatographic purification of active compounds. Silica gel column chromatography of hexane soluble fractions of Anemarrhenae Rhizoma and Embeliae Radix gave very active sub-fractions, AA-4 and ES-4, and their inhibition activities of $LTB_4$ binding to human neutrophil at $30\;{mu}g/ml$ were 78% and 62%, respectively. From these results we could anticipate new $LTB_4$ receptor antagonist from herbal drugs, and the block of $LTB_4$ effects may provide beneficial in neutrophil mediated diseases such as inflammation and bronchial asthma.
