Polarized electric field effects on the regulation of succinate dehydrogenase activity in amphibian muscle and liver: kinetic study.
Electropolarity treatment (0.8 V/DC/Cm) was given to the gastrocnemius muscle of Bufo melanostictus every day for 5 min. for 5 days, and kinetic study of succinate dehydrogenase (SDH) in muscle and liver was conducted with different effectors - sodium malonate, ethylene diamine tetra acetic acid (EDTA), calcium chloride (CACl2) and sodium citrate. Of the four modulators tested, the malonate and EDTA inhibited while sodium citrate and CACl2 activated the enzyme. The significance of the modulation in SDH activity to different extents was discussed.
