| Abstract |
|
This study was undertaken to measure the activity of myeloperoxidase and leukocyte peroxidase of hen. 70 hens were decapitated to observe the activity of enzymes according to ages. The activity of peroxidase by the Lowry's method with bovine serum albumin as standard. Gel filtration chromatography was carried out of sephacryl S-300 column. The results obtained were summarized as follows; 1. The mean of specific activity of myeloperoxidase and leukocyte peroxidase was 16.80(units/mg) and 15(units/mg), respectively. 2. The specific activity of myeloperoxidase in 35 days hen was significantly increased and showed almost the same level of activity to 350 days hen. 3. The specific activity of leukocyte peroxidase in 35 days hen was significantly increased and showed a little increased tendency from 210 days to 350 days hen. 4. On the sephacryl S-300 column chromatography, two separated peaks of myeloperoxidase activity were observed. The molecular weights of myeloperoxidase were 57,000 dalton and 13,700 dalton. |
