“ Histidine (5–50 mM) increased the level of AMP-primed dialysate adenosine in a concentration-dependent manner.”
“In the presence of NA (10 µM), histidine , a scavenger of highly active singlet oxygen (1O2), significantly increased concentration of adenosine.”
“In the presence of histidine (25 mM), a marked elevation of NA and adenosine was observed.”
