Combinational Western and oriental medicine therapies for geriatric syndrome

GERIATRICS & GERONTOLOGY INTERNATIONAL, Issue 4 2005
K Iwasaki
Oriental medicines often assist patients who cannot be treated with Western medicines. Although the exact mechanisms of oriental medicines are not known, their clinical usefulness has been proven in various diseases, including geriatric syndrome. In this review we explain progress in oriental medicine and how oriental medicines are effective in treating geriatric syndrome. [source]

Cosmeceutical properties of polysaccharides from the root bark of Ulmus davidiana var. japonica

INTERNATIONAL JOURNAL OF COSMETIC SCIENCE, Issue 2 2007
Sang Yong Eom
In Korea and China, Ulmus davidiana var. japonica has been used as a traditional oriental medicine for the treatment of difficulty in urination, skin inflammation, etc. In order to investigate the potential of a polysaccharide extract from Ulmus davidiana var. japonica as a cosmetic ingredient, we measured its moisturizing effect, photo-induced cytotoxicity, and anti-inflammatory effect. After hydrolysis, HPLC experiments showed that the composition of the polysaccharide extract was mainly rhamnose, galactose, and glucose. The molecular weight of the obtained Ulmus davidiana root extract was 20 000. The intrinsic viscosity was 90 dL/g. In a moisturizing test conducted through the measurement of water loss in a desiccator and of moisture content with a Corneometer CM820, Ulmus davidiana root extract showed almost the same moisturizing effect as hyaluronic acid. In an assay for inhibition of the H2O2-activated release of PGE2, IL-6, and IL-8 in normal human fibroblast cell lines, Ulmus davidiana root extract showed an inhibitory activity of PGE2 release in a dose-dependent manner (up to 85.9% at a concentration of 0.1%). The percent inhibition of the release of IL-6 was in the range of 45.6,64.5% (H2O2 was used as the positive control). Moreover, the release of IL-8 was completely inhibited in the entire concentration range (>0.0025%). In a test of recovery from photo-induced damage after UVA irradiation (3 J/cm2), the cell recovery of human fibroblasts increased to levels two times higher than that of the positive control, which was UVA-damaged cells in the absence of Ulmus davidiana root extract (up to 60.2% at 3.0% of Ulmus davidiana root extract). In a photo-induced cytotoxicity assay in the presence of promethazine as a photosensitizer, Ulmus davidiana root extract showed approximately 48% of the increased cell viability of the control. Therefore, Ulmus davidiana root extract may be useful for the development of a cosmetic ingredient. [source]

The nature of touch therapy related to Ki: Practitioners' perspective

NURSING & HEALTH SCIENCES, Issue 2 2003
Sung Ok Chang PhD
Abstract Touch therapy related to Ki, a type of healing touch, has been regarded as one of the distinct therapeutic modalities in traditional oriental medicine. The present study attempted to develop a substantive theory about helping patients using touch therapy related to Ki, by exploring the views of practitioners who are using this therapeutic modality within the context of the Korean society. A grounded theory approach was applied during the collection and analyses of data. The core category, main categories and trajectory of helping patients during the use of touch therapy related to Ki was delineated. Helping patients while using touch therapy related to Ki was found to be a dynamic process with each participant actively engaged in increasing the activating, potential power of the human being. These findings have value in understanding the embedded meaning of the healing process through touch therapy within the context of Ki. [source]

Ganoderma lucidum extract attenuates the proliferation of hepatic stellate cells by blocking the PDGF receptor

PHYTOTHERAPY RESEARCH, Issue 6 2009
Guei-Jane Wang
Abstract Hepatic fibrosis is an outcome of chronic liver diseases. The activation and proliferation of hepatic stellate cells (HSCs) is a key event in liver injury. The fruiting body of Ganoderma lucidum has long been a popular oriental medicine for treating liver diseases. The aim of this present study was to investigate the antiproliferative effects of the triterpenoid-rich extract (GLT) of G. lucidum in a cell line of rat HSCs (HSC-T6) stimulated with platelet-derived growth factor (PDGF)-BB. DNA synthesis was investigated by bromodeoxyuridine (BrdU) incorporation. Flow cytometry using propidium iodide (PI) labeling was carried out to analyse the cell cycle distribution and apoptosis. , -Smooth muscle actin (, -SMA) was used to evaluate extracellular matrix deposition, and western blotting was performed to measure cyclins D1 and D2, and phosphorylation of the PDGF, -receptor (PDGF,R), Akt and JNK. The results indicated that the GLT attenuated BrdU incorporation in a concentration-dependent manner with an IC50 of 8.52 ± 0.33 µg/mL. The inhibitory effect of the GLT was associated with downregulation of cyclins D1 and D2, and PDGF,R and Akt phosphorylation, upregulation of JNK phosphorylation, and a reduction in , -SMA expression. These results indicated that G. lucidum inhibits PDGF-BB-activated HSC proliferation possibly through blocking PDGF,R phosphorylation, thereby indicating its efficacy for preventing and treating hepatic fibrosis.

Effect of Bupleuri Radix Extracts on the Toxicity of 5-Fluorouracil in HepG2 Hepatoma Cells and Normal Human Lymphocytes

BASIC AND CLINICAL PHARMACOLOGY & TOXICOLOGY, Issue 4 2008
Su Jin Kang
We sought to assess whether Bupleuri Radix extract enhances 5-fluorouracil-induced cytotoxicity in HepG2 hepatoma cells, while protecting normal blood lymphocytes. Bupleuri Radix, used for treatment of liver disease in oriental medicine, possesses antitumour properties; it induces apoptosis through cell arrest in tumour cells, but does not affect normal lymphocytes. In this study, we evaluated the protective and enhancing effects of Bupleuri Radix on 5-fluorouracil-induced cytotoxicity in HepG2 cells and normal lymphocytes. Treatment with Bupleuri Radix increased the micronuclei frequency and DNA damage, resulting from 5-fluorouracil treatment. However, when human lymphocytes were cotreated with Bupleuri Radix and 5-fluorouracil, the frequency of 5-fluorouracil-induced micronuclei decreased. Although the extent of 5-fluorouracil-induced DNA damage, determined by single-cell gel electrophoresis, increased after treating HepG2 cells with Bupleuri Radix, it decreased in normal lymphocytes. When cells were treated with 20 µM 5-fluorouracil and 200 µg/ml Bupleuri Radix simultaneously, Bax protein increased in HepG2 cells at 24 hr; however, p21 and p53 proteins were up-regulated in normal human lymphocytes. Cotreatment with 200 µg/ml Bupleuri Radix and 20 µM 5-fluorouracil resulted in cell arrest at the late G1/early S phase in HepG2 cells (55.80 ± 0.19%) and normal lymphocytes (97.19 ± 0.27%). In addition, Bupleuri Radix and 5-fluorouracil treatment increased mitochondria membrane potential collapse only in HepG2 cells (19.02%), while it was not changed in lymphocytes. In conclusion, our findings suggest that Bupleuri Radix may be effective as a therapeutic agent to treat hepatomas. [source]
