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.

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.
