Objective:we investigated the alteration of plasma vascular peroxidase(VPO)levels in patients coronary artery diseases,and the effect of VPO on oxidized low-denisity lipoprotein(ox-LDL)vascular inflammatory reaction in endothelial cells.

Recent reseach found a novel peroxidase named vascular peroxidase (VPO) has the same function as myeloperoxidase (MPO).

AsA pretreatment significantly enhanced AsA content and the activity of ascorbic acid peroxidase (APX) in maize seedlings under normal culture condition.

After the treatment on the dry seed or germinatlve seed of corn, wheat or mung beau with the specified electromagnetic wave, add adequate water and put in under the condition of 27℃ for culture, then analyse the specimen of th bud or the seeding reqularly for the activiation of ascorbic acid peroxidase and the contents of GSH and ascorbic acid.

Cloning and Expression Analysis of An APX Gene from Betula platyphylla

4), and detecting activi- ties of superoxide dismutase (SOD) and ascorbate peroxidase (APX), the effects of chilling stress under weak light on functions of photosystem I (PSI) and photosystem II (PSII) in leaves of a wild type soybean variety ‘ZYD00019’ and a cultivar soybean variety ‘Zaoshu No.

Three wheat varieties with different aluminum tolerances were used to study ascorbic acid contents, and ascorbic oxidase and APX activities in root apoplast and symplasm of wheat seedling under aluminum stress.
