PURPOSE Wedelia chinensis is a common ingredient of anti-inflammatory herbal medicines in Taiwan and southern China. Inflammation is involved in promoting tumor growth, invasion, and metastasis. This study aims to test the biological effects in vivo of W. chinensis extract on prostate cancer. EXPERIMENTAL DESIGN The in vivo efficacy and mechanisms of action of oral administration of a standar...

Tupistra chinensis is a widely used medicinal plant in Hubei Province, China. In our study, we investigated the effect of polysaccharides component from Tupistra chinensis on mice in vivo. The mice H22 hepatocarcinoma animal model was established firstly. Then, the mice were fed with different doses of polysaccharides derived from Tupistra chinensis (one time each day). The neoplasm growth cond...

The gliding bacterium Flexibacter sp. strain FS-1 exhibits inducible resistance to chloramphenicol (Cmr) and tetracycline (Tcr). Either chloramphenicol or tetracycline alone induced a Cmr Tcr phenotype. The resistance is apparently not plasmid encoded.

Ants are one of the most successful and widespread organisms in the world. Although ants of the genus Pachycondyla (Hymenoptera: Formicidae: Ponerinae) are predominantly tropical in distribution, Pachycondyla chinensis (Emery) is especially abundant in temperate zones in Asia. Recently, P. chinensis has also become an abundant invasive ant species in the United States. However, it was well-know...

BACKGROUND The insect predator, Arma chinensis, is capable of effectively controlling many pests, such as Colorado potato beetle, cotton bollworm, and mirid bugs. Our previous study demonstrated several life history parameters were diminished for A. chinensis reared on an artificial diet compared to a natural food source like the Chinese oak silk moth pupae. The molecular mechanisms underlying ...

The hepatoprotective effects of a Taiwanese crude herb, Hwang-hua-mih-tsay (Wedelia chinensis (Osbeck) Merr.), were investigated. Acute hepatitis was induced by three hepatotoxins: carbon tetrachloride and acetaminophen in mice, and D(+)-galactosamine in rats. After treatment with W. chinensis (300 mg/kg, p.o.) at 2, 6 and 10 hours, a reduction in the elevation of serum glutamate oxaloacetic tr...

The effect of Cuscuta chinensis extract on the rabbit penile corpus cavernosum (PCC) was evaluated in the present study. Penises obtained from healthy male New Zealand white rabbits (2.5-3.0 kg) were precontracted with phenylephrine (Phe, 10 µmol l(-1)) and then treated with various concentrations of Cuscuta chinensis extract (1, 2, 3, 4 and 5 mg ml(-1)). The change in penile tension was record...

In the present study, we determined the complete mitochondrial DNA (mtDNA) sequences of two species of Cistopus, namely C. chinensis and C. taiwanicus, and conducted a comparative mt genome analysis across the class Cephalopoda. The mtDNA length of C. chinensis and C. taiwanicus are 15706 and 15793 nucleotides with an AT content of 76.21% and 76.5%, respectively. The sequence identity of mtDNA ...

BACKGROUND Glioma remains the most common cause of brain cancer-related mortality. Glioma accounts for 50-60% of brain cancer. Due to their low toxicity and infrequent side effects, traditional herbs have been increasingly popular. Coptis Chinensis is commonly used in cancer treatment in combination with other Chinese Medicine herbs. However, little is known about its biological functions and m...
