Title: Blood sulfhydryl changes in methemoglobinemia, a possible factor in protective effects of nitrite and paraminoproplophenone.
Abstract: The data show that two components of blood sulfhydryl, measured by methods devised for GSH and SH, behaved differently under certain experimental conditions: the concentration of the latter increased while that of the former decreased. This behavior occurred during methemoglobin formation, taking place both in vivo and in vitro when a direct methemoglobin-former (nitrite) was used, but only in vivo when an indirectly-acting agent (PAPP) was used. Some quantitative parallelism between the formation of methemoglobin and the formation of new SH groups was demonstrated. Alloxan, a poor methemoglobin former, significantly reduced the concentration of blood GSH without appreciably affecting the SH level.
