  scavengers mannitol
The lack of effect of radical scavengers (mannitol, Tris) indicates that HO- radicals produced in the bulk phase play no role in inactivation.
      
Addition of the ?OH scavengers mannitol or dimethylthiourea to the reaction mixtures resulted in a significant decrease in the rate of DBAN oxidation.
      
In contrast, addition of the hydroxyl radical scavengers mannitol and salicylic acid had no effect.
      
scavengers (mannitol and ethanol) suggest that oxidative modification of the proteins in Fenton's medium should be associated not only with hydroxyl radical but also with ferryl and perferryl ions and with the radical PH3.

The effects of oxygen free radicals on myocardial α_1-adrenoceptor and its subtypesand β-adrenoceptor were observed by the method of radioligand binding assay in rat.The experiments showed: (1) .OH and reduced the B_(max) of α_1-adrenoceptors bindingto  ̄(125)IBE2254 by 55% and 36%, respectively. (2) The K_I values of α_1-adrenoceptorswere increased by .OH (by 171% ),but not by (3)Both .OH and increased theratio of α_(1A) vs α_(1B) subtypes. (4) β-adrenoceptors were not changed by either .OH or (5)Oxygen free radical scavengers mannitol and superoxide dismutase were capableof preventing the changes of α_1-adrenoceptor and its subtypes induced by oxygen freeradicals. The above results suggest that oxygen free radicals can reduce the number andaffinity of myocardial α_1-adrenoceptors, of which the α_(1B) subtype is more accessible tothe changes.

BU Fengquan(Norman Bethune University of Medical Science, Changchun, 130023)(Received Dec. 2, 1996) The reaction of hydrogen peroxide with cytochrome c makes them coupled to lead to the hydroxylation of 4-nitrophenol. In situ electrochemical probe was used to detect the hydroxylation of 4-nitrophenol, which can avoid the tedious extraction procedure, the loss of the active species and the interference of some colored substances in the detection of 4-nitrocatechol by spectroscopic method. The hydroxyl radical scavengers mannitol and sodium benzoate did not eliminate hydroxylation, but the inhibitory effect of uric acid on the hydroxylation lead to the formation of the ferryl species of the protein during the reaction. These studies suggest that the electrochemical probe might efficiently detect the trace 4-nitrocatechol from the onset of the hydroxylation reaction and thus provides a more sensitive tool.
