The activity of defense enzymes in the seedlings which seeds soaked and sprayed with Zhongshengmycin at 3-4 leaf and 5d before transplant, increased mostly in 24h inoculating with Xoo, was middle resistance CBB7. The activity of defense enzymes in mature rice, treating with Zhongshengmycin as seedlings, was enhanced much in Fengjing.
Expression character of defense enzymes and soluble proteins in the interaction between soybean single variety and Cercospora sojina different strains or different varieties and single strain were assayed.
The activities of three defense enzymes, polyphenoloxidase, peroxidase and phenylalanine ammoniayase in tobacco plants treated with Lewisx heptasaccharide at 10 μg/mL increased by 70.7%, 150.0% and 142.8%, respectively. The mechanism of the induced resistance is discussed.
Moreover, cells were also protected from paraquat toxicity in the presence of antioxidant defense enzymes SOD and catalase.
Changes in Antioxidant Defense Enzymes after d-amphetamine Exposure: Implications as an Animal Model of Mania
Pre-operative vitamin E administration decreased mucosal lipid peroxidation increased the levels of antioxidant defense enzymes and lowered the lysosomal enzymes.
The levels of antioxidant defense enzymes, superoxide dismutase, glutathione peroxidase, catalase and glutathione were decreased as compared to the sham-operated controls.
Circulating lipid peroxide, antioxidant components and the activities of defense enzymes were estimated in uterine cervical carcinoma patients (before and after radiotherapy and radiotherapy combined chemotherapy) and compared with controls.
