By the method of artificial soil pollution,an exposure experiment with different concentrations of pyrene(0,60,120,240,480,960 μg·kg-1)was conducted to determine the cytochrome P450 and MDA contents and the glutathione-S-transferase(GST),superoxide dismutase(SOD),peroxidase(POD)and catalase(CAT)activities in earthworm gut after exposure for 1,3,7 and 14 days.

The carboxylesterase, glutathione-S-transferase, acetylcholinesterase properties of an insecticide resistant (HJ-R) and a susceptible (HD-S) strains of Helicoverpa armigera were studied in two days after hatching to fourth instar larvae.

11) and its transgenics co-expressing both GST (glutathione-S-transferase) and CAT1 (catalase) was used as the material of this.

GSH, GR, SOD, CAT, ROS, and TOSC in mouse liver were measured after exposure to lead acetate of different concentrations for one week.

-、H2O2 contents and GR activity have been studied in tobacco leaves under different curing conditions.

Lactate dehydrogenase(LDH) activity,myocardial infarct size,the release of ATP and purine nucleotide catabolites,activities of SC、CAT and GR were observed.

Cloning and analysis of glutathione reductase gene from Leymus multicaulis;

Heat-shock pretreatment could improve salt resistance and enhance glutathione reductase (GR)activity and proline content in maize seedlings during salt stress.

RNA was extracted and separated from the fresh leaves of Leymus multicaulis plants under salt stress and then primers were designed according to two conserved regions of glutathione reductase reported in many species.

Advances in reactive nitrogen species mediated activation of hepatic microsomal glutathione transferase 1;

Cloning and expression of a new gene of glutathione transferasefrom Clonorchis sinensis;

Objective To amplify a new encoding gene of microsomal glutathione transferase (mGST) from adult Clonorchis sinensis, determine whether it had intron or not, express it in Escherichia coli and purify the recombinant protein.
