A chinese herbal decoction, danggui buxue tang, stimulates proliferation, differentiation and gene expression of cultured osteosarcoma cells: genomic approach to reveal specific gene activation.

Danggui Buxue Tang (DBT), a Chinese herbal decoction used to treat ailments in women, contains Radix Astragali (Huangqi; RA) and Radix Angelicae Sinensis (Danggui; RAS). When DBT was applied onto cultured MG-63 cells, an increase of cell proliferation and differentiation of MG-63 cell were revealed: both of these effects were significantly higher in DBT than RA or RAS extract. To search for the biological markers that are specifically regulated by DBT, DNA microarray was used to reveal the gene expression profiling of DBT in MG-63 cells as compared to that of RA- or RAS-treated cells.

A Chinese herbal decoction prepared from Radix Astragali and Radix Angelicae Sinensis induces the expression of erythropoietin in cultured Hep3B cells.

Danggui Buxue Tang (DBT), a Chinese medicinal decoction used commonly for treating women's ailments, contains Radix Astragali (RA) and Radix Angelicae Sinensis (RAS). According to Chinese medicinal theory, this decoction is to nourish the blood function; this, however, has not been demonstrated on the molecular level. In order to reveal the hematopoietic effect of this decoction, DBT was applied to cultured Hep3B human hepatocellular carcinoma cells.

Verification of the formulation and efficacy of Danggui Buxue Tang (a decoction of Radix Astragali and Radix Angelicae Sinensis): an exemplifying systematic approach to revealing the complexity of Chinese herbal medicine formulae.

This article exemplifies a systematic approach to revealing the complexity of Chinese herbal medicine formulae through three levels of scientific research: standardization of herbs, verification of ancient formulae and mechanism studies. We use Danggui Buxue Tang (DBT) as an example for this approach. Among thousands of traditional Chinese medicine herbal formulae, almost all of which consist of multiple herbs, DBT is one of the simplest.

A Chinese herbal decoction, Danggui Buxue Tang, activates extracellular signal-regulated kinase in cultured T-lymphocytes.

Danggui Buxue Tang (DBT) is prepared from Radix Astragali and Radix Angelicae Sinensis. This Chinese herbal decoction has been shown to stimulate the proliferation of T-lymphocytes; however, the action mechanism of this stimulation has not been revealed. In cultured T-lymphocytes, application of DBT markedly induced the cell proliferation, the release of interleukin-2, -6 and -10, as well as the phosphorylation of extracellular signal-regulated kinases (ERK).

Danggui buxue tang--a Chinese herbal decoction activates the phosphorylations of extracellular signal-regulated kinase and estrogen receptor alpha in cultured MCF-7 cells.

Danggui buxue tang (DBT), a Chinese herbal decoction used to treat ailments in women, contains radix Astragali (Huangqi; RA) and radix Angelicae Sinensis (Danggui; RAS). The weight ratio of RA to RAS used in DBT must be 5:1 as stipulated as early as AD 1247; however, DBT's mechanism of action has never been described. Here, the estrogenic effects of DBT were investigated by determining the phosphorylations of estrogen receptor alpha (ER alpha) and extracellular signal-regulated kinase 1/2 (Erk1/2) in cultured MCF-7 cells.

A Chinese herbal decoction, Danggui Buxue Tang, prepared from Radix Astragali and Radix Angelicae Sinensis stimulates the immune responses.

Danggui Buxue Tang (DBT), a Chinese medicinal decoction that is used commonly for treating women's ailments, contains Radix Astragali and Radix Angelicae Sinensis. The ratio of Radix Astragali and Radix Angelicae Sinensis used in DBT should be 5 : 1 as described in China in 1247 A.D.

A polysaccharide isolated from Cordyceps sinensis, a traditional Chinese medicine, protects PC12 cells against hydrogen peroxide-induced injury.

Cordyceps sinensis, a well-known traditional Chinese medicine, possesses activities in anti-tumour, anti-oxidation and stimulating the immune system; however, the identity of active component(s) is not determined. By using anti-oxidation activity-guided fractionation, a polysaccharide of molecular weight approximately 210 kDa was isolated from cultured Cordyceps mycelia by ion-exchange and sizing chromatography. The isolated polysaccharide, having strong anti-oxidation activity, contains glucose, mannose and galactose in a ratio of 1 : 0.
