Dansam, the root of Salvia miltiorrhiza BGE. (Labiatae), has a bitter and a slightly 'cold' property. and is nontoxic. It has been used for the treatment of diseases such as tumors, bruises, gynecologic diseases, menoxenia, anemia and so forth. As an oriental medicine pathway, anal therapy has many kinds of treatments, Retention enema is one the most useful, advantageous methods of anal therapy. This experiment was performed in order to study the effect of an aqueous extract of Salviae radix root(SRRAE) on Immediate type allergic reaction by Retention enema. The results were obtained as follows, 1. SRRAE inhibited compound 48/80-induced Immediate type allergic reaction 100% with the dose of 0.1g/kg by anal treatment. However, SRRAE showed no significant inhibitory effect on the same reaction by oral treatment. When mice were pretreated with SRRAE at a concentration ranging from 0.001 to 1.0g/kg, by intra-anal treatment, the serum histamine levels were reduced in a dose-dependent manner. 2. SRRAE also inhibited by 79.8% local cutaneous allergic reaction activated by anti-dinitrophenyl (DNP) IgE. 3. SRRAE close-dependently inhibited the histamine release from rat peritoneal mast cells(RPMC) by anti-DNP IgE., but SRRAE not inhibited compound 48/80-induced histamine release. 4. SRRAE dose-dependently inhibited tumor necrosis $factor-\;{\alpha}$ $(TNF-\;{\alpha}$) production from RPMC by anti-DNP IgE. Moreover, the level of cAMP in RPMC, when SRRAE was added, significantly increased compared with that of a normal control. According to the above results, anal therapy(Retention enema) of SRRAE may be beneficial in the treatment of systemic and local Immediate type allergic reactions.

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.

Objectives: This study examined the effects of salvianolic acid B (SAB) on exhaustive exercise-induced cardiac muscle damage to rats. Methods: The study was carried out with 12-week-old young adult male Sprague-Dawley rats. Thirty-six rats were divided into 3 groups; normal (n=12), exhaustive exercise group (ExS, n=12) and exhaustive exercise with SAB (ExS+SAB, n=12). Five days before exhaustive exercise, SAB were medicated for 5 days in ExS+SAB group. Rats in ExS and ExS+SAB group were forced to swim for 150 minutes and then they were sacrificed, while rats in normal group were sacrificed at rest. After that, blood was collected and cardiac muscle tissue damage indices were analyzed. Results: Serum aspartate transaminase activity and lactate dehydrogenase activity were significantly lower in ExS+SAB group than in ExS group. Serum creatine phosphokinase activity of ExS+SAB was significantly lower than ExS group. However, the content of serum creatinine had no difference between ExS and ExS+SAB group. In the H&E stained left ventricle myocardium, ExS group showed signs of myocardial damage such as sporadic fragmentation of myocardial fibers, interstitial edema, cytoplasmic eosinophilia and neutrophils infiltration. However, ExS+SAB group alleviated the severity of the signs of myocardial damage. In the myocardial dihydroethidium staining, optical density was remarkably decreased in ExS+SAB group compared to ExS group. Furthermore, the up-regulation of Bax/Bcl-2 ratio was observed in ExS+SAB group compared with ExS group. Conclusions: The above results suggest that SAB may protect cardiac muscle damage via antioxidant activity and prevention of apoptosis.

BACKGROUND: Horticultural plant growth under field and/or greenhouse conditions is affected by the climate changes (e.g., temperature, humidity, and rainfall). Therefore investigation of hydroponics on field horticultural crops is necessary for year-round production of the plants regardless of external environment changes under plant factory system with artificial light sources. METHODS AND RESULTS: Common sage (Salvia plebeia), nasturtium (Tropaeolum majus), and hooker chive (Allium hookeri) plants were hydroponically culturing in the plant factory with blue-red-white LEDs (Light-Emitting Diodes) and fluorescent lights (FLs). Leaf numbers of common sage under mixture LED and FL treatments were 134% and 98% greater, respectively than those in the greenhouse condition. In hooker chives, unfolded leaf numbers were 35% greater under the artificial lights and leaf elongation was inhibited by the conventional sunlight compared to the artificial light treatments. Absorption pattern of NO₃-N composition in hydroponic solution was not affected by the different light qualities. CONCLUSION(S): Plant factory system with different light qualities could be applied for fresh-leaf production of common sage, nasturtium, and hooker chive plants culturing under field and/or greenhouse. Controlled light qualities in the system resulted in significantly higher hydroponic growth of the plants comparing to conventional greenhouse condition in present.

Objectives: We investigated the effects of Clean-DM4 (C-DM4), a polyherbal extract consisting of Coptidis Rhizoma, Salviae Miltiorrhiza Radix, and Cinnamomi Cortex on high fat diet (HFD)-induced obesity and diabetes in mice. Methods: The C57BL/6 mice (6 weeks) were fed a HFD for 8 weeks and then administrated with C-DM4 extract at 500 mg/kg (p.o.) once daily for 4 weeks. The changes of body weights, calorie intakes, and fasting blood glucose (FBG) levels were measured in mice. The serum levels of glucose, insulin, total cholesterol, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) were measured in mice by enzyme-based assay. It was also observed the histological changes of pancreas, liver, and fat tissues with hematoxylin and eosin (H&E) staining. Results: The increase of calorie intakes and FBG levels in HFD-induced obesity mice was significantly decreased by oral administration of C-DM4 extract. C-DM4 extract administration was significantly reduced the increased levels of glucose, insulin, total cholesterol, AST, and ALT in obesity mice. In addition, C-DM4 extract inhibited lipid droplet accumulation in liver tissues of obesity mice, hyperplasia of pancreatic islets, and enlargement of adipocytes in adipose tissues. Conclusions: Our study indicates that C-DM4 extract could help improve obesity and to prevent diabetes progression.

BACKGROUND/OBJECTIVES: Activating brown adipose tissue (BAT) and browning of white adipose tissue (WAT) can protect against obesity and obesity-related metabolic conditions. Cryptotanshinone (CT) regulates lipid metabolism and significantly ameliorates insulin resistance. Adenosine-5'-monophosphate (AMP)-activated protein kinase (AMPK), a receptor for cellular energy metabolism, is believed to regulate brown fat activity in humans. MATERIALS/METHODS: The in vivo study included high-fat-fed obese mice administered orally 200/400 mg/kg/d CT. They were evaluated through weight measurement, the intraperitoneal glucose tolerance test (IPGTT), intraperitoneal insulin tolerance test (IPITT), cold stimulation test, serum lipid (total cholesterol, triglycerides, and low-density lipoprotein) measurement, hematoxylin and eosin staining, and immunohistochemistry. Furthermore, the in vitro study investigated primary adipose mesenchymal stem cells (MSCs) with incubation of CT and AMPK agonists (acadesine)/inhibitor (Compound C). Cells were evaluated using Oil Red O staining, Alizarin red staining, flow cytometry, and immunofluorescence staining to identify and observe the osteogenic versus adipogenic differentiation. Quantitative real-time polymerase chain reaction and the Western blot were used to observe related gene expression. RESULTS: In the diet-induced obesity mouse model mice CT suppressed body weight, food intake, glucose levels in the IPGTT and IPTT, serum lipids, the volume of adipose tissue, and increased thermogenesis, uncoupling protein 1, and the AMPK pathway expression. In the in vitro study, CT prevented the formation of lipid droplets from MSCs while activating brown genes and the AMPK pathway. AMPK activator enhanced CT's effects, while the AMPK inhibitor reversed the effects of CT. CONCLUSION: CT promotes adipose tissue browning to increase body thermogenesis and reduce obesity by activating the AMPK pathway. This study provides an experimental foundation for the use of CT in obesity treatment.

This research examined whether feeding single extracts or complex extracts of Bulnesia sarmienti, together with a high fat diet, could improve serum lipid levels and reduce fat mass in rats. Test groups were fed the extracts, combined with a high fat diet, for eight weeks, and subdivided into seven groups: normal, control, and five treatment groups (BS: B. sarmienti extracts; BS-S: B. sarmienti and Salvia miltiorrhiza Bunge extracts; BS-M: B. sarmienti and Morus alba Linne extracts; BS-SM1: B. sarmienti, Salvia miltiorrhiza Bunge and Morus alba Linne extracts; and BS-SM2: BS-SM1 extracts at a 2-fold concentration). After feeding the test substance for 8 weeks, no significant differences were found for food intake, water intake, change in body weight, or food efficiency ratios (FER) among the groups. However, serum LDL-cholesterol had increased by 14.1% in the BS-S group. When compared with the control group, total cholesterol levels in the BS, BS-S, BS-M, BS-SM1, and BS-SM2 groups were reduced by 36.0, 14.5, 40.4, 17.5, and 22.5%, respectively, with the greatest change shown in the BS-M group. In terms of triglycerides, levels in BS, BS-S, BS-M, BS-SM1, and BS-SM2 had decreased by 41.9, 8.5, 62.3, 17.7, and 14.5%, respectively. Compared to the control group, the BS group showed a significant decrease in fat mass. In conclusion, the BS and BS-M groups showed significant effects with respect to improved serum lipid profiles and body fat mass when they were fed a high fat diet in combination with the respective extracts.

Chia (Salvia hispanica L.) seed, originated from Central America, is a nutritious food especially rich in dietary fiber and protein. In this study, we investigated the quality and sensory characteristics of Yanggang with chia seed powder (CSP). Red bean paste was replaced with CSP at 0% (Control), 1% (CSP1), 2% (CSP2), 3% (CSP3) and 4% (CSP4). The pH values of chia seed Yanggang tended to decrease from Control (6.84) to CSP4 (6.67); whereas, the moisture contents of Yanggang samples tended to increase. The soluble solid contents of CSP4 were the highest ($3.33^{\circ}Bx$), as compared to the Control which showed the lowest values ($2.77^{\circ}Bx$). In the CSP-added groups, the L-value (lightness), a-value (redness) and b-value (yellowness) were increased, while the ${\Delta}E$ (total color difference) was decreased, as compared to the control group. Hardness and springiness were both increased from control ($49.77g/cm^2$ and 464.80%, respectively) to CSP4 ($72.21g/cm^2$ and 532.43%, respectively). However, cohesiveness decreased from control (47.41%) to CSP4 (37.34%). Chewiness and adhesiveness showed no significant group-wise difference (p<0.05). Total polyphenol content ranged from 7.23 to 10.73 mg GAE/100 g, with a lower ABTS $IC_{50}$ of the CSP-added groups than that of the control group. Samples from the CSP-added as well as Control groups showed no significant differences among all items on the sensory evaluation test, except flavor. The results indicated that CSP had significant effects on the soluble solid contents and texture of Yanggang. Thus, the addition of 2% of CSP is desirable for making Yanggang.
