This study tried to integrate the traditional oriental medical theories and results of experimental studies of herbaceous plants on anti-diabetes. And I tried to analyze recent experimental study trend on the anti-diabetic herb. I searched anti-diabetic herb studies on 4 korean databases and 10 korean journals by keywords, 'diabetes', 'blood glucose', 'glycometabolism', 'pancreatic ${\beta}$-cell', etc. In order to see detail review, searching was performed from 2000 to 2010. And I searched 125 study cases concerning anti-diabetic herb and 72 varieties herbaceous plants used in study of anti-diabetes. and I analyzed the choice motives of each herb for anti-diabetic study, the extract methods and anti-diabetic evaluation contents. And I analyzed anti-diabetic herbs from a traditional oriental medical point of view. When the researchers chose herb for anti-diabetic experiment, just 8.8% of the choice was based on the oriental medical evidences. I found that 60.6% of the herb shown to be effective in diabetes experimentally had oriental medical theory-based Properties(性). There were studies with whole plants(16.8%), aqueous extract(45.6%), methanol extract(8.0%), ethanol extract(8.0%) and comparative studies of more than 2 types of extracts or various fractions(18.4%). The most frequent experimental diabetic models was diabetic mouse induced by streptozotocin(STZ)(87.8%). And there were db/db mouse(6.7%), ob/ob mouse(1.1%), etc. 33.6% of all studies just measured hematological indices of diabetes, and 66.4% researches analyzed details. To improve herbaceous plants study on diabetes, we oriental medical scientists have to integrate the oriental medical theories and results of experimental studies.

Objective: This study investigated the effect of purified medical herb extracts such as Alisma canaliculatum and Polyporus umbellatuson adipogenic differentiation of human bone marrow derived mesenchymal stromal stem cells (hBMSCs). Methods: Two different medical herb were extracted using hot distilled water. The optimal concentration of extracts were fixed at 100 ng/ml by means of cell viability and cytotoxic assay. To test the adipogenic differentiation ability of extracts, we induced the adipogenesis of hBMSCs for 21 days. At day 5, the cell was harvested to check mRNA and protein expression level of adipogenic related factors. The efficacy of lipid droplet formation was evaluated using the oil-red O staining method at days 21. Results: Two different medical herb extracts have no toxicity on hBMSCs. And two different medical herb extracts significantly decreased formation of lipid droplet compared with control groups in hBMSCs. The A. canaliculatum extract group showed the lowest mRNA and protein expression level of adipossgenic related transcription factors. This data suggests that extract of A. canaliculatum and P. umbellata decrease the adipogenic differentiation of hBMSCs. Conclusions: Our findings indicate that water-extract of A. canaliculatum and P. umbellata will be useful therapeutic reagents for prevention of obesity related disease such as diabetes, hyperlipidemia, coronary artery disease, and osteoporosis.

This study was conducted to evaluate the efficacy of Cheongawongagam on osteoporosis rat. A total of 35 rats were divided into seven groups; Normal control(SD-Nr), experimental control group(OVX-CTL), positive control group(OVX-17β-E2) and herb extracts group[Eucommia ulmoides(OVX-EU-E), Juglandis semen(OVX-JR-SE), Acanthopanax senticosus(OVX-AS-E) extract and Cheongawongagam extracts(OVX-JAEG-E)]. All control group, and herb extracts group were ovariectomized. After the 3 weeks recovery period, herb extract group were orally administered 200 mg / kg of the EU-E, JR-SE, AS-E and JAEG-E for 12 weeks. In the OVX-CTL, 17β-estradiol(E2) was administered subcutaneously on the back of the rats at a dose of 0.03 ug/sc. Their body weight, serum total cholesterol, triglyceride, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), Leukotriene B4 (LTB4), calcium (Ca), estradiol, osteocalcin, and deoxypyridinoline (DPD) concentration were measured. Also, we investigated mRNA expression of inflammatory cytokine, MMP-2, MMP-9, and bone tissue. As a result, total cholesterol was significantly decreased in the OVX-AS-E and OVX-JAEG-E. ALP was significantly increased and osteocalcin, DPD was significantly decreased in OVX-JAEG-E. The expression of inflammatory mediators (TNF-α, IL-1β, LTB4, COX-2, NOS-2), inflammatory cytokines IL-1β and MMP-9 mRNA were significantly decreased in OVX-JAEG-E. Histologic examination of the femur showed that bone mineral density, and bone mass were increased and bone marrow were decreased in the OVX-JAEG-E group. The above experiment shows that cheongawongagam extract were effective in the prevention and treatment of osteoporosis.

Psoriasis is one of the most common inflammatory skin disorders, with a global prevalence of 2% - 3%. It is an autoimmune skin disorder characterized by excessive generation of plaques on the skin with typical long-lasting red, itchy, and scaly lesions. In this study, we aimed to elucidate the anti-psoriatic effect of the methanolic extract of Persicaria senticosa (PS), a bioactive edible plant extract used in traditional medicine, using a mouse model of imiquimod (IMQ)-induced psoriasis. The daily topical application of IMQ could induce human psoriasis-like lesion. The extract ameliorated IMQ-induced psoriasis. Furthermore, hematoxylin and eosin staining and the Psoriasis Area and Severity Index (PASI) scores indicated that topical application of PS led to an improvement in erythema, scaling, and thickness scores of the mouse dorsal skin and a considerable decrease in the epidermal thickness of the ear and dorsal skin in the IMQ-induced psoriatic mouse model. We also studied the effect of PS on the proliferation of keratinocytes using HaCaT cells. The extract inhibited cell proliferation and IL-6 and pSTAT3 expression induced by M5 cocktail (comprising interleukin [IL]-1α, IL-17A, IL-22, oncostatin M, and tumor necrosis factor-α) in HaCaT cells. Thus, PS might serve as a potential therapeutic agent for the treatment of psoriasis.
