Extract of Rhus verniciflua Stokes Induces p53-Mediated Apoptosis in MCF-7 Breast Cancer Cells.

Rhus verniciflua Stokes has long been used as a food supplement and traditional herbal medicine for various ailments in East Asia. We evaluated the anticancer effects of Rhus verniciflua Stokes extract (RVSE) on MCF-7 cells by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, flow cytometry, annexin V/7-AAD staining, and western blotting. In addition, the gallic acid content of RVSE was assayed using high-performance liquid chromatography. RVSE inhibited the growth of MCF-7 cells in a dose-dependent manner by inducing apoptosis in the sub-G1 phase. RVSE also significantly increased the number of apoptotic cells and increased the expression of p53 and p21 in a dose-dependent manner. Furthermore, RVSE treatment increased the Bax:Bcl-2 ratio and the levels of apoptosis-related factors, such as cleaved caspase-3 and -9 and PARP, in MCF-7 cells. Our findings suggest that the proapoptotic effect of RVSE on MCF-7 cells is mediated by p53, p21, and the intrinsic mitochondrial cascade. Thus, RVSE shows promise for the prevention and treatment of breast cancer.

Heat-Processed Scutellariae Radix Protects Hepatic Inflammation through the Amelioration of Oxidative Stress in Lipopolysaccharide-Induced Mice.

The present study evaluated the effects of heat-processed Scutellariae Radix (Scutellaria baicalensis) on lipopolysaccharide (LPS)-induced liver injury in mice. Scutellariae Radix heat-processed at 160[Formula: see text]C or 180[Formula: see text]C was orally administered at a dose of 100 mg/kg body weight for three days before the intraperitoneal injection of LPS, and the effects were compared with those of vehicle-treated LPS administered to control mice. The administration of Scutellariae Radix decreased the elevated serum monocyte chemotactic protein-1 (MCP-1), interleukin-6 (IL-6), reactive oxygen species (ROS), nitrite/nitrate, peroxynitrite, and hepatic functional parameters, and reduced the increased ROS in the liver. The augmented expressions of hepatic oxidative stress and inflammation-related proteins, phospho-p38, phosphorylated extracellular signal-regulated kinase, phosphorylated c-Jun N-terminal kinase, nuclear factor-[Formula: see text] B p65, activator protein-1, cyclooxygenase-2, inducible nitric oxide synthase, MCP-1, intercellular adhesion molecule-1, tumor necrosis factor-[Formula: see text], and IL-6, were downregulated by the heat-processed Scutellariae Radix. Hematoxylin-eosin staining showed that the increased hepatocellular damage in the liver of LPS-treated mice improved with the administration of heat-processed Scutellariae Radix. Overall, the ameliorative effects of Scutellariae Radix were superior to those when heat-processed at 180[Formula: see text]C. Our results indicate that heat-processed Scutellariae Radix acts as an anti-inflammatory agent by ameliorating oxidative stress in the liver of mice with LPS-induced liver injury.

Polyphenol isolated from Corni Fructus, 7-O-galloyl-D-sedoheptulose, modulates advanced glycation endproduct-related pathway in type 2 diabetic db/db mice.

7-O-Galloyl-D-sedoheptulose (GS) is the bioactive polyphenol isolated from the low-molecular-weight fraction of Corni Fructus (Cornus officinalis Sieb. et Zucc.). The present study was conducted to examine whether GS has an ameliorative effect on the liver of type 2 diabetic db/db mice. GS (20 or 100 mg/kg body weight/day, per os) was administered every day for 6 weeks to db/db mice, and its effect was compared with vehicle-treated db/db and m/m mice. The administration of GS decreased the elevated serum glucose, leptin, insulin, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), resistin, and hepatic functional parameters, and reduced the increased fluorescent advanced glycation endproducts (AGEs) and reactive oxygen species in the liver. The db/db mice exhibited the up-regulation of receptor for AGEs (RAGE) and AGE-related proteins; however, GS treatment significantly reduced those expressions. Moreover, the augmented expressions of oxidative stress- and inflammation-related proteins, phospho-extracellular-signal regulated kinase 1/2, phospho-c-Jun N-terminal kinase, nuclear factor-kappa B, activator protein-1, monocyte chemotactic protein-1, intracellular adhesion molecule-1, TNF-α, and IL-6, were down-regulated by GS administration. Hematoxylin-eosin staining showed that the increased hepatocellular damage in the liver of db/db mice improved with GS administration. The present results support the evidence for GS ameliorating hepatic damage through the RAGE-mediated inflammation pathway.

A clinical pilot study comparing traditional acupuncture to combined acupuncture for treating headache, trigeminal neuralgia and retro-auricular pain in facial palsy.

Traditional acupuncture (TA) and ear acupuncture (EA) are used for treatment of headache, trigeminal neuralgia, and retro-auricular pain. The purpose of this study is to develop effective treatment using combined acupuncture (CA) which consists of TA and EA and to set clinical protocols for future trials. Participants were divided into TA (n = 15) control and CA (n = 34) experimental groups. Obligatory points among Korean Five Element Acupuncture and optional individual points along with symptom points were used in the TA group. The CA group was exposed to ear points of Fossion and TA. Acupuncture treatment consisted of six mandatory sessions per patient over 3 weeks and extended to 12 sessions. Pain was assessed using the visual analogue scale. We compared TA to CA and researched their relevant publications. No significant difference was observed between the two groups (p = 0.968) which showed pain-alleviating tendency. Pain alleviation was significantly different after the fifth and sixth sessions (p = 0.021, p = 0.025), with headache being the most significantly relieved (F = 4.399, p = 0.018) among the diseases. When assessing pain intensity, both the Headache Impact Test and the Migraine Disability Assessment Scale should be adopted for headache and the fractal electroencephalography method be used in pain diseases. In the future, studies should consist of TA, EA, and CA groups; each group having 20 patients. Treatment number should to be no less than 10 sessions. Korean Five Element Acupuncture should be a compulsory inclusion along with individual points being optional inclusion in TA. EA could be selected from Nogier, Fossion and so forth. In conclusion, acupuncture treatment, whether TA or CA, showed pain alleviation in headache, trigeminal neuralgia, and retro-auricular pain, but no significant difference was seen between groups. Prospective, well-controlled, and relevant protocols using multimodal strategies to define the role of TA, EA, and CA are needed.

Sa-Ahm Five Element acupuncture.

This study aimed to review the clinical basis for Sa-Ahm Five Element acupuncture. This form of acupuncture uses the Five-Shu acupoints and the tonification-sedation treatments based on the creation and control cycles of the Five Elements. A total of 28 books and papers from the ancient "Nan-Ching" to the modern "Medical Acupuncture" were used to study clinical practices. Sa-Ahm Five Element acupuncture could be practiced in different ways depending upon differential diagnoses. These diagnoses include theories of excess and deficiency of Yin and Yang, seven emotions, ZangFu (organ, viscera), and comparing pulse diagnosis and meridian therapy to meridian palpation. Clinical trials and guidelines for the practice of Sa-Ahm acupuncture should be created to allow for a more evidence-based clinical approach to using this technique.

Pinellia ternata, Citrus reticulata, and their combinational prescription inhibit eosinophil infiltration and airway hyperresponsiveness by suppressing CCR3+ and Th2 cytokines production in the ovalbumin-induced asthma model.

BACKGROUND AND OBJECTIVE: This study was aimed to analyse the curative effects of Pinellia ternata, Citrus reticulata, and their combination on airway hyperresponsiveness (AHR) to inhaled methacholine, pulmonary eosinophilic infiltration, Th2 cytokine production, and IgE and histamine production in a murine model of asthma. METHODS: For this purpose, BALB/c mice were systemically sensitized to ovalbumin (OVA) followed intratracheally, intraperitoneally, and by aerosol allergen challenges for 12 weeks. We examined the development of pulmonary eosinophilic accumulation, control of Th2 cytokine, immunoglobulin E (IgE), and histamine productions in a murine model of asthma. RESULTS: Our data suggest that the therapeutic mechanism by which Pinellia ternata, Citrus reticulata, and their combinational prescription effectively treats asthma is based on reductions of eosinophil infiltration, eotaxin receptor (CCR3), histamine, OVA-specific IgE productions in serum, and Th2 cytokines (IL-5, IL-13) by marked reductions of IL-5 and IL-13 mRNA expression in lung tissue. CONCLUSIONS: These findings provide evidence that Pinellia ternata, Citrus reticulata, and their combination play a regulatory role in allergic inflammation and offer therapeutic approaches as novel CCR3 antagonists for treatment asthma. However, it is not clear whether pharmacological activities of prescription composed of two herbs are potentiated due to synergistic effect or additive effect.

A study of the Sa-Ahm Five Element acupuncture theory.

This study is a review of the theoretical basis of Sa-Ahm Five Element acupuncture devised about 360 years ago. A total of 21 books and papers ranging from the ancient Huang Di Nei Jing to modern biomedical acupuncture for pain management were researched in relation to the Five Shu points. Gao-Wu, in the Chinese Ming Dynasty, used the Five Shu points for the first time based on the creation cycle as the tonification and sedation treatment, termed the "tonification and sedation treatment of self meridian". Since then, and for no particular reason, this method has been rarely used until Sa-Ahm's new doctrine, which includes the concept of the destruction cycle, was asserted. Sa-Ahm Five Element acupuncture is a method in which the Five Shu points are used from the viewpoints of the simultaneous tonification and sedation methods that are based on the promotion and control cycles. Although it is currently the most utilized method in accordance with the practitioner's points, this method is in need of designated guidelines by which Sa-Ahm acupuncture can be practiced effectively.

Fritillaria cirrhosa, Anemarrhena asphodeloides, Lee-Mo-Tang and cyclosporine a inhibit ovalbumin-induced eosinophil accumulation and Th2-mediated bronchial hyperresponsiveness in a murine model of asthma.

Asthma is a chronic inflammatory disorder of the airways characterized by excess production of Th2 cytokines and eosinophil accumulation in the lungs. Fritillaria cirrhosa, Anemarrhena asphodeloides and Lee-Mo-Tang are well-known herbs used in oriental medicine for the treatment of asthma and bronchial inflammation. To clarify the anti-asthmatic effects of Fritillaria cirrhosa bulbus, Anemarrhena rhizoma and Lee-Mo-Tang, we examined the development of pulmonary eosinophilic accumulation, control of Th2 cytokine, immunoglobulin E (IgE) and histamine productions in a murine model of asthma. Eosinophil cell proliferation was performed by [(3)H]thymidine uptake, eosinophilic accumulation. Cell counts in bronchoalveolar lavage fluid were investigated by means of fluorescence activated cell sorter analysis and control of Th2 cytokine, IgE and histamine productions were investigated by RT-PCR and ELISA. Moreover, lung tissue was histologically analysed. The suppressive effects of Fritillaria cirrhosa bulbus, Anemarrhena rhizoma and Lee-Mo-Tang on eosinophil recruitment and airway inflammation were demonstrated throughout the reduction of eosinophil numbers. This result correlated with a marked reduction IL-5, IL-13 and IL-4 levels in the bronchoalveolar lavage fluid. Ovalbumin-specific IgE levels were also decreased in serum. Fritillaria cirrhosa bulbus, Anemarrhena rhizoma and Lee-Mo-Tang have deep inhibitory effects on airway inflammation by suppression of Th2 cytokines (IL-4, IL-5 and IL-13), IgE, histamine production, reduction eosinophilic accumulation and increase of interferon-gamma production.

Inhibitory effects of Actinidia polygama extract and cyclosporine A on OVA-induced eosinophilia and bronchial hyperresponsiveness in a murine model of asthma.

Actinidia polygama is one of the well known herb used in oriental medicine for treatment of anti-inflammatory and many allergic diseases. Anti-asthmatic effects of A. polygama in the development of OVA-induced eosinophilia and hyperresponsiveness in murine model of asthma have not been fully investigated in vivo. Cyclosporine A (CsA) has been shown to inhibit single allergen-induced allergic inflammation such as eosinophilic and lymphocytic infiltration and mRNA expression for interleukin (IL)-4 and IL-5. Asthma is a chronic inflammatory disease of the mucosa and is associated with excess production of Th2 cytokines and eosinophil influx in lung. To clarify the anti-inflammatory and anti-asthmatic effects of A. polygama and CsA, we examined the influence of A. polygama fructus extract (APF) and CsA on the development of pulmonary eosinophilic inflammation in murine model of asthma. Our results have shown that APF and CsA have profound inhibitory effects on the accumulation of eosinophills into airways, with the reduction of eosinophil and total lung leukocyte number by reducing IL-4, IL-5, IL-13 and IgE levels in the BALF. Moreover, APF decreased eosinophil CCR3 expression and CD11b expression in lung cells. These results indicate that APF has a deep inhibitory effect on airway inflammation and hyperresponsiveness in murine model of asthma and play a crucial role as an immunomodulator which possess anti-inflammatory and anti-asthmatic property by modulating the relationship between Th1/Th2 cytokine imbalance.

Liriopis tuber inhibit OVA-induced airway inflammation and bronchial hyperresponsiveness in murine model of asthma.

Liriope platyphylla is one of the well-known herb used in oriental medicine for treatment asthma and bronchial and lung inflammation. Anti-asthmatic effects of Liriope platyphylla in the development of OVA-induced airway inflammation and murine asthma model have not been fully investigated in vivo. Asthma is a chronic inflammatory disease of the mucosa and is associated with excess production of Th2 cytokines and eosinophil accumulation in lung. To clarify the anti-inflammatory and anti-asthmatic effects of Liriope platyphylla, we examined the influence of liriopis tuber (LRT) on the development of pulmonary eosinophilic inflammation in murine model of asthma. Our results have shown that LRT were demonstrated on the accumulation of eosinophills into airways, with reduction of eosinophil, total lung leukocytes numbers by reduction IL-5, IL-13, IL-4 and IgE levels in the BALF and serum. Moreover, LRT decreased eosinophil CCR3 expression and CD11b expression in lung cells. These results indicate that LRT has a deep inhibitory effects on airway inflammation and hyperresponsiveness in murine model of asthma and play an crucial role as a immunomodulator which possess anti-inflammatory and anti-asthmatic property by modulating the relationship between Th1/Th2 cytokine imbalance.

Effect of Radix Ginseng and Radix Trichosanthis on the melanogenesis.

Melanogenesis is a well known physiological response of human skin exposed to ultraviolet light, genetic reasons and other sources. In this study, we conducted to evaluate the effects of Radix Ginseng (RG) and Radix Trichosanthis (RT) on the melanogenesis in the B16 melanoma cells. The cells were treated for 48 h with RT at concentrations ranging from 1 to 50 microg/ml, RG at concentration of 10-1000 microg/ml, or RG at various doses (10-1000 microg/ml) with 25 microg/ml RT. Treatment with RT alone dose-dependently suppressed tyrosinase activity and melanin content compared with untreated control, and significantly inhibited cell proliferation. However, RG at various concentrations did not exhibit any significant change of them. Treatment with RT in the presence of various concentrations of RG suppressed tyrosinase activity and melanin content, similar to treatment with RT alone, but slightly increased cell proliferation. Furthermore, tyrosinase protein level was significantly decreased in treatment with 25 microg/ml RT alone and with a combination of 100 microg/ml RG. These results indicate that treatment with RG and RT significantly inhibits the melanogenesis in B16 cells, and raise the possibility that this combination may be effective in the whitening agent for the skin.
