The Development of a Fluorescent Microsatellite Marker Assay for the Pitaya Canker Pathogen ().

Pitaya canker, caused by , is a destructive disease that significantly threatens the safety of the pitaya industry. The authors of previous studies have mainly focused on its biological characteristics and chemical control. However, there are no molecular markers available thus far that can be used for the population genetics study of this pathogen.

Aqueous extract of Rabdosia rubescens leaves: forming nanoparticles, targeting P-selectin, and inhibiting thrombosis.

The hot water extract of Rabdosia rubescens was traditionally used as an antithrombotic medicine. To explore its antithrombotic utility and mechanism, we carried out a series of in vitro and in vivo assays in this study. In vitro platelet aggregation assay showed that the half maximal inhibitory concentration values of aqueous extract of R.

One single HPLC-PDA/(-)ESI-MS/MS analysis to simultaneously determine 30 components of the aqueous extract of Rabdosia rubescens.

In China the leaves of Rabdosia rubescens have been cooked in water and widely drank to treat inflammatory and pain related diseases. To explore the components that were possibly absorbed by people the aqueous extract of the leaves was prepared, and one single HPLC-PDA/(-)ESI-MS/MS analysis was developed to simultaneously determine the components. Using the HPLC-PDA analysis 39 peaks were found in the aqueous extract, while using the (-)ESI-MS/MS analysis we were able to identify 30 peaks represented components, including 5 nucleic acids, 21 phenolic acids and 4 diterpenoids.

Study on the pharmacokinetics drug-drug interaction potential of Glycyrrhiza uralensis, a traditional Chinese medicine, with lidocaine in rats.

Drug-drug interaction potentials of an herbal medicine named Glycyrrhiza uralensis was investigated in rats via in vitro and in vivo pharmacokinetic studies. P(450) levels and the metabolic rate of lidocaine in the liver microsomes prepared from different treatment groups were measured. In a separate in vivo pharmacokinetic study, the pharmacokinetic parameters of lidocaine in plasma and urine were estimated.

Inhibition of cytochrome P450 enzymes by rhein in rat liver microsomes.

Rhein, an active ingredient extensively found in plants such as Aloe, Cassitora L., rhubarb and so on, has been used for a long time in China. Pharmacological tests revealed that rhein not only had a strong antibacterial action, but also may be useful in cancer chemotherapy as a biochemical modulator.

Effect of the water extract and ethanol extract from traditional Chinese medicines Angelica sinensis (Oliv.) Diels, Ligusticum chuanxiong Hort. and Rheum palmatum L. on rat liver cytochrome P450 activity.

Angelica sinensis (Oliv.) Diels (DG), Ligusticum chuanxiong Hort. (CX) and Rheum palmatum L.

Metabolism and effect of para-toluene-sulfonamide on rat liver microsomal cytochrome P450 from in vivo and in vitro studies.

Aim: To study the in vivo and in vitro metabolism and the effect of para-toluene-sulfonamide (PTS) on cytochrome P450 enzymes (CYP450).

Methods: Total CYP450 and microsome protein content were determined after iv pretreatment of rats with PTS. CYP-specific substrates were incubated with rat liver microsomes.
