LABILE IRON POOL FORMATION IN RAT’S BLOOD UNDER RHABDOMYOLYSIS
S. G. Shandrenko
The labile nonheme iron pool formation in blood under glycerol induced rhabdomyolysis in rats has been investigated. This iron is not included in transferrin, thereby it is redox-active. Rhabdomyolysis was caused by intramuscular injection of 50% glycerol in a dose of 10 ml/kg. In the first day it has been registered that the blood plasma free heme content increased 10 times and the liver heme-oxigenase activity increased 6 times. Plasma redox-active iron pool formation has been registered by EPR method. Such iron was absent in the control group. This iron pool content in the interval from the 1st to the 6st day was more than 2 mg/l and significantly higher than the transferrin iron level. The plasma iron pool unshielded by transferrin may be one of oxidative stress causes.
Key words: iron, transferrin, rhabdomyolysis.
