[The effect of cytochrome c preparations on the cerebral circulation in cerebral ischemia].
Biotechnological cytochrome c, heme-tetradecapeptide (HTDP) and animal cytochrome c were studied for their effects on intact and brain ischemic rats. In the latter case, the compounds were administered before ischemia induction and 15 min after artery ligation. It was found that the cytochrome c preparations did not virtually affect the cerebral circulation in intact rats. In cerebral ischemia, the cytochrome C preparations increased circulation, showing their more profound effects in case of preadministration of the drugs. The dose-independent effects of HTDP may be associated with the higher transmembranous permeability and the saturation phenomenon of this compound.
