Soybean curd residue (SCR), known as a major waste product of soybean processing, is the water-insoluble fraction which is removed by filtration during soymilk production. For these reasons, SCR was usually considered as food waste. SCR might have a good potential as a functional food material, value-added processing and utilization. SCR contains high-quality protein and consists of a good source of nutrients, including protein, oil, dietary fiber, minerals, along with un-specified monosaccharides and oligosaccharides. Also, SCR might be a potential source of low cost protein for human consumption. However, SCR could be a source of bacterial contamination when during food processing. This study was aimed to investigate antibacterial capacity of natural product through detecting relationship between SCR and microbial. We isolated five bacterial strains from SCR and elucidated antibacterial activity of nature medicines to extend storage capacity of food made with SCR. Thus, the extract which showed antibacterial effects in Corynebacterium calloonae and Raoultella amithinolytica is a combination of seven kinds of extracts: Glycyrrhiza uralensis, Cudrania tricuspidata, Salvia miltiorrhiza Bunge, blueberry, Acorus gramineus, Ginkgo biloba L., Camellia sinensis. This study suggested that antibacterial activities of natural medicines could be used for extension of storage capacity in SCR-contained food.

Objectives: The aim of this study was to review the research trends in the treatment of pharmacopuncture for vascular dementia in Traditional Chinese medicine. Methods: We searched for articles in the China National Knowledge Infrastructure (CNKI) database from January 2000 to August 2020. Results: Among the total 63 articles, 9 articles were selected. All studies were randomized controlled trial studies. The Diagnostic and Statistical Manual of Mental Disorders (DSM) was most frequently used as diagnostic criteria. Effective rate and Activity of Daily Living (ADL) were most commonly used as outcome measurements. Angelica gigantis Radix (當歸), Salvia miltiorrhiza Bunge (丹蔘), and Astragali Radix (黃芪) were the most commonly used ingredients in pharmacopuncture. Joksamni (ST36) and Sinsu (BL23) were the most commonly used acupoints for pharmacopuncture treatment. Based on the Risk of Bias (RoB) of these 9 articles, the overall quality of studies was low. Conclusions: Pharmacopuncture could be considered for the treatment of vascular dementia. In the future, various systematic studies on dementia are needed.

Objective : Salvia miltiorrhiza Bunge (Labiatae) (SM), an eminent herbal plant, has been widely used in traditional Chinese medicine for the treatment of vascular diseases such as hypertension. The aim of this study was to determine whether SM inhibits production of nitrite, an index of NO, and proinflammatory cytokines in lipopolysaccharide (LPS)-treated RAW 264.7 macrophages. And this study investigated whether or not SM could reduce tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$)-induced inflammatory response in human vascular aortic smooth muscle cells (HASMC) and umbilical vein endothelial cells (HUVEC). Methods : Cytotoxic activity of SM on RAW 264.7 cells was using 5-(3-caroboxymeth-oxy phenyJ)-2H-tetra-zolium inner salt (MTS) assay. We measured the NO production using Griess Reagent System. Production of Proliflammatory cytokines was measured by Enzyme-Linked Immunosorbent Assay (ELISA). Results : Our results indicated that SM significantly inhibited the LPS-induced NO production accompanied by an attenuation of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), IL-6 and monocyte chemoattractant protein (MCP)-1 formation in macrophages. SM decreased TNF-${\alpha}$-induced IL-8, IL-6 production, and intracellular adhesion molecule (ICAM)-1 and vascular cell adhesion molecule (VCAM)-1 expression. Conclusion : These results indicate that SM has potential as an anti-inflammatory agent.

Backgrounds: Tanshinone IIA (TIIA), a phenanthrenequinone derivative extracted from Salvia miltiorrhiza BUNGE, has been reported to be a natural anti-cancer agent in a variety of tumor cells. However, the effect of TIIA on gastric cancer cells remains unknown. In the present study, we investigated the influence of TIIA on the malignant phenotype of SGC7901 gastric cancer cells. Methods: Cells cultured in vitro were treated with TIIA (0, 1, 5, $10{\mu}g/ml$) and after incubation for different periods, cell proliferation was measured by MTT method and cell apoptosis and cell cycling were assessed by flow cytometry (FCM). The sensitivity of SGC7901 gastric cancer cells to anticancer chemotherapy was investigated with the MTT method, while cell migration and invasion were examined by wound-healing and transwell assays, respectively. Results: TIIA (1, 5, $10{\mu}g/ml$) exerted powerful inhibitory effects on cell proliferation (P < 0.05, and P < 0.01), and this effect was time- and dose-dependent. FCM results showed that TIIA induced apoptosis of SGC7901 cells, reduced the number of cells in S phase and increased those in G0/G1 phase. TIIA also significantly increased the sensitivity of SGC7901 gastric cancer cells to ADR and Fu. Moreover, wound-healing and transwell assays showed that TIIA markedly decreased migratory and invasive abilities of SGC7901 cells. Conclusions: TIIA can reverse the malignant phenotype of SGC7901 gastric cancer cells, indicating that it may be a promising therapeutic agent.

Tanshinone IIA (Tan IIA) is a pharmacologically active substance extracted from the rhizome of Salvia miltiorrhiza Bunge (also known as the Chinese herb Danshen), and is widely used to treat atherosclerosis. The pregnane X receptor (PXR) is a nuclear receptor that is a key regulator of xenobiotic and endobiotic detoxification. Tan IIA is an efficacious PXR agonist that has a potential protective effect on endothelial injuries induced by xenobiotics and endobiotics via PXR activation. Previously numerous studies have demonstrated the possible effects of Tan IIA on human umbilical vein endothelial cells, but the further mechanism for its exerts the protective effect is not well established. To study the protective effects of Tan IIA against hydrogen peroxide ($H_2O_2$) in human umbilical vein endothelial cells (HUVECs), we pretreated cells with or without different concentrations of Tan IIA for 24 h, then exposed the cells to $400{\mu}M$ $H_2O_2$ for another 3 h. Therefore, our data strongly suggests that Tan IIA may lead to increased regeneration of glutathione (GSH) from the glutathione disulfide (GSSG) produced during the GSH peroxidase-catalyzed decomposition of $H_2O_2$ in HUVECs, and the PXR plays a significant role in this process. Tan IIA may also exert protective effects against $H_2O_2$-induced apoptosis through the mitochondrial apoptosis pathway associated with the participation of PXR. Tan IIA protected HUVECs from inflammatory mediators triggered by $H_2O_2$ via PXR activation. In conclusion, Tan IIA protected HUVECs against $H_2O_2$-induced cell injury through PXR-dependent mechanisms.

Cryptotanshinone (CPT) is a natural compound isolated from traditional Chinese medicine Salvia miltiorrhiza Bunge. In the present study, the regulatory effect and potential mechanisms of CPT on tumor necrosis factor alpha ($TNF-{\alpha}$) induced lectin-like receptor for oxidized low density lipoprotein (LOX-1) were investigated. Human umbilical vein endothelial cells (HUVECs) were cultured and the effect of $TNF-{\alpha}$ on LOX-1 expression at mRNA and protein levels was determined by Real-time PCR and Western blotting respectively. The formation of intracellular ROS was determined with fluorescence probe $CM-DCFH_2-DA$. The endothelial ox-LDL uptake was evaluated with DiI-ox-LDL. The effect of CPT on LOX-1 expression was also evaluated with SD rats. $TNF-{\alpha}$ induced LOX-1 expression in a dose- and time- dependent manner in endothelial cells. $TNF-{\alpha}$ induced ROS formation, phosphorylation of $NF-{\kappa}B$ p65 and ERK, and LOX-1 expression, which were suppressed by rotenone, DPI, NAC, and CPT. $NF-{\kappa}B$ inhibitor BAY11-7082 and ERK inhibitor PD98059 inhibited $TNF-{\alpha}-induced$ LOX-1 expression. CPT and NAC suppressed $TNF-{\alpha}-induced$ LOX-1 expression and phosphorylation of $NF-{\kappa}B$ p65 and ERK in rat aorta. These data suggested that $TNF-{\alpha}$ induced LOX-1 expression via ROS activated $NF-{\kappa}B/ERK$ pathway, which could be inhibited by CPT. This study provides new insights for the anti-atherosclerotic effect of CPT.

Tests of stability and toxicity, and clinical evaluation of anti-acne activity suggest that cryptotanshinone, a constituent of the roots of Salvia miltiorrhiza Bunge, is an effective active ingredient for acne vulgaris treatments. Acne vulgaris, called acne or pimples, is the most common disease of the pilosebaceous follicle unit of the skin. It affects nearly 80% of people between the ages of 11 and 30. Approximately 30% of teenagers have acne of sufficient severity to require medical treatment. Acne is a follicular disorder of the skin. It occurs in specialized pilosebaceous units on the face and body. Acne develops when these specialized follicles undergo pathologic alterations that result in the formation of non-inflammatory lesions (comedones) and inflammatory lesions (papules, pustules and nodules). An abnormality of keratinizing epithelium of these follicles, thought to be due to the action of sebum synthesized and secreted by the androgen-sensitive sebaceous glands, leads to inflammation induced by the follicular bacterium Propionibacterium acnes. Therapy involves treatments that modify these pathogenic factors and includes drugs with antikeratinizing, antibacterial and antiseborrheic actions. Acne vulgaris is a very frequent disease, seen primarily in adolescents, involving the sebaceous follicles. Acne vulgaris is characterized by a great variety of clinical inflammatory and non-inflammatory lesions: comedones, papules, pustules, nodules, cysts and scars. Acne vulgaris is a multi-factorial disease. Although its pathogenicity is unclear, extensive studies have shown that hyperseborrhea, superinfection by P. acnes and endocrinologic androgenic changes play a role in the development of acne vulgaris.

화학방부제는 항균활성은 좋지만 많은 부작용이 보고되고 있어 최근에는 인체에 해가 없으며 방부 기능과 자체 효능이 있는 천연방부제의 개발이 활발하다. 또한 천연물의 흡수율을 높이기 위한 방법으로 분자량이 커서 인체에 잘 흡수되지 않아 저분자화를 시키기 위한 방법으로 균주를 이용하여 발효하는 것도 늘어나고 있는 추세이다. 이에 천연방부제가 방부 효과는 지속되어야 하고 첨가했을 때 품질에 손상을 주지 않아야 하며, 향, 색과 성분에 영향을 끼치지 않아야 한다는 요건들을 충족시켜야 한다. 따라서 본 연구는 인체에 해가 없으며 항균활성이 좋은 황금, 단삼, 관중을 선정하였다. 식물은 모두 에탄올로 추출하였고, 발효균주로는 B. subtilis, L. casei, S. cerevisiae와 누룩에서 분리한 Asp. oryzae로 액체와 고체발효를 하여 발효 전과 발효 후의 유효성분의 함량을 비교하였다. 항균활성을 알아보기 위해 C. albicans, S. aureus, P. aeruginosa 세균 3종과 진균은 E. coli로 억제력을 탐색하였다. 천연방부제 개발로 사용하기 위해서는 항균활성이 있고 이러한 실험을 수행하여 다음과 같은 결과를 얻었다. 1. 원산지, 굵기와 용매에 따른 수율은 황금은 중국산이며 굵기는 2,800㎛로 50% ethyl alcohol 추출물에서 21.88%, 단삼은 국내산으로 굵기는 2,800㎛이며 50% ethyl alcohol 추출물에서 25.62%, 관중은 중국산으로 굵기는 2,800㎛, 70% ethyl alcohol 추출물에서 6.50%의 수율을 얻었다. 2. L. casei로 1일 액체 발효했을 때 수율은 황금 66.8%, 단삼 84.8%, 관중 73.0%였다. B. subtilis로 고체발효한 황금과 단삼은 24.40%, 39.30%, 관중은 L. casei로 발효 했을 때 11.10%의 수율을 얻었다. 3. 액체발효 후 황금에서 S. aureus 균주에 대하여 9mm 정도의 clear zone이 확인되었고, 단삼과 관중 발효에서는 항균력이 확인되지 않았다. 4. 황금을 L. casei로 고체발효 했을 때 C. albicans와 S. aureus에서 높은 항균활성을 보였다. 단삼은 S. cerevisiae로 고체발효 했을 때 S. aureus에서 항균활성을 보였다. 관중은 L. casei, S. cerevisiae로 고체발효 했을 때 E. coli와 S. aureus에서 항균활성이 높게 나타났다. 발효하지 않았을 때보다 발효 후의 항균활성이 매우 높았다. 5. 유효성분의 변화는 고체발효하지 않은 황금에서는 baicalin 101.57, baicalein 28.26, wogonin 5.33mg/g이었고, S. cerevisiae로 고체발효 했을 때는 baicalin 94.31, baicalein 30.41, wogonin 3.57mg/g로 baicalein의 함량은 증가된 것으로 확인되었다. 발효하지 않은 단삼에서는 salvianolic acid A가 1.82mg/g 이었으며, S. cerevisiae로 고체발효했을 때는 5.70mg/g으로 증가하였다. 관중의 유효성분은 flavaspidic acid AP, flavaspidic acid PB, flavaspidic acid AB, flavaspidic acid BB로 나타났다.
