[Elevation of the blood kynurenine level in caffeine-induced anxiety].
Concentration of neuroactive tryptophane--kynurenine metabolite was studied in healthy men volunteers in conditions of anxiety artificially elicited by caffeine. At peak of the alarm the level of the kynurenine significantly increased and came to norm after anxiety cessation. Possible causes of this increase are discussed. High correlation has been obtained between the kynurenine concentration and initial values of personal and reactive anxiety. The conclusion is made about the participation of the kynurenine in formation of personal and reactive anxiety in man.
