to determine if blood histamine levels were increased during human sepsis and septic shock , plasma histamine was measured using a very sensitive radioenzyme assay employing histamine n-methyltransferase ( hnmt ) in the following patient groups : normal controls ( n = 76 ) , nonseptic critically ill ( n = 12 ) , nonseptic shock ( n = 2 ) , sepsis without shock ( n = 28 ) , and septic shock ( n = 41 ) .
