“…Autism and controls had comparable levels of stimulated cAMP production in platelets (Berry-Kravis 1992; Berry-Kravis and Sklena 1993), potentially useful models of neural signal transduction (Stahl 1977;Camacho and Dimsdale 2000). Plasma cAMP levels have been used as a physiologic indicator of sympathetic arousal (Huhman, Hebert et al 1991), emotional stress (Arnetz 1979), noise related stress-induced anxiety (Iwamoto, Ishii et al 1995), childhood psychoses (Goldberg 1984), and hyperkinetic behavior of autism and mental retardation (Hoshino, Kumashiro et al 1980). Plasma levels of cAMP are elevated in medicated and unmedicated autistic children relative to controls, but plasma cAMP levels are reduced relative to mentally retarded patients with hyperkinetic disorder (Hoshino, Kumashiro et al 1980;Cook 1990).…”

Cyclic AMP (cAMP) is a second messenger involved in many processes including mnemonic processing and anxiety. Memory deficits and anxiety are noted in the phenotype of fragile X (FX), the most common heritable cause of mental retardation and autism. Here we review reported observations of altered cAMP cascade function in FX and autism. Cyclic AMP is a potentially useful biochemical marker to distinguish autism comorbid with FX from autism per se and the cAMP cascade may be a viable therapeutic target for both FX and autism.

“…In the present study, mirror drawing test, watching a horror video and arithmetic under intermittent noise were used sequentially, and the response to the stressors should be interpreted as cumulative response to acute psychological stress. If a subject is exposed to a psychological test alone for a long time, the subject may become accustomed to it 21) . Therefore, we used combined exposure to the tests mentioned in this study.…”

School of Medicine-The aim of this study was to e v a l u a t e h e a r t r a t e v a r i a t i o n a n d u r i n a r y catecholamines in response to acute psychological stress in hand-arm vibration syndrome (HAVS) patients and healthy controls. LF% (indicator of both the sympathetic and parasympathetic nervous activity), HF% (indicator of the parasympathetic nervous activity) and their ratio LF/HF (indicator of sympathovagal b a l a n c e ) w e r e c a l c u l a t e d f r o m s h o r t -t e r m electrocardiographic data from 16 HAVS patients and 14 healthy controls before and immediately after exposure to acute psychological stress. Urinary catecholamines (norepinephrine, epinephrine and dopamine) were analyzed from urine samples collected from every subject during rest and after exposure. The LF% and LF/HF of the patients significantly increased after exposure. The after exposure LF/HF of the patients was significantly greater than that of the controls. The amount of norepinephrine in the patients significantly increased after exposure. The after exposure amount of norepinephrine and epinephrine in the patients were significantly greater than the respective amount of the controls. The results of the present study indicated the predominance of sympathetic tone in the cardiac sympathovagal balance and greater sensitivity of the sympathoadrenal medullary system in response to acute psychological stress in the patients than in the healthy controls.

To investigate heart rate variability in response to psychological tests (Japanese version of Stroop color word test and mirror drawing test) in 29 hand-arm vibration syndrome (HAVS) patients, 16 of them with vibration-induced white finger (VWF) and 13 without VWF, and 10 healthy controls of similar age, heart rate variability during spontaneous and deep (6 cycles a minute) breathing in supine position before and after exposure to the psychological tests was examined calculating frequency domain components such as low frequency (LF) power-index of both the sympathetic and parasympathetic activity, high frequency (HF) power-index of the parasympathetic activity and LF/HF-index of the sympathovagal balance. The group of all patients and the group without VWF indicated significant increase in LF/HF in the deep breathing measurement after exposure to the psychological tests. The result suggests that the sympathetic tone in the sympathovagal balance predominated in the HAVS patients which means that they had larger sensitivity of the sympathetic nervous system to the psychological tests.
