Dysthymic depressed patients showed platelet-serotonin (pS) + plasma-free serotonin values greater than normal as well as plasma noradrenaline values lower than normal during supine resting period (0'). Conversely, no significant differences were observed in the 0' values of any other of the measured parameters: systolic, diastolic and differential blood(More)
The oral glucose tolerance test (OGTT) with plasma neurotransmitter assays and blood pressure measurements were performed on 68 hypertensive (A and B) and 68 paired normal controls (group C). Those patients who failed to show significant or persistent blood pressure reductions throughout OGTT constitute group A (37 subjects); and those who did show(More)
Major depressed patients showed greater heart rate, noradrenaline, and free-serotonin values than normal. Conversely, platelet-serotonin values in major depressed patients were significantly lower than normal. Patients registered the normal differential blood pressure reduction during orthostasis. They also revealed progressive and significantly higher(More)
Levels of noradrenaline, adrenaline, dopamine, free serotonin, platelet serotonin, and cortisol were measured in the plasma of duodenal ulcer patients and controls. All subjects received antacids, and these substances were also measured. During relapse, all patients showed raised noradrenaline, adrenaline, dopamine, free serotonin, and cortisol values. In(More)
We report five consecutive cases of patients with acute pancreatitis resistant to conventional treatment who improved dramatically with clonidine. All patients showed greatly elevated noradrenaline, adrenaline and cortisol plasma levels (physiological indicators of stress) which fell abruptly upon initiation of clonidine therapy. The clonidine test(More)
We routinely measured plasma neurotransmitters and hormone levels in order to investigate the role of stress on many types of diseases. In this study, we present results obtained from patients with severe chronic diseases. The study sample consisted of 88 patients (asthmatics, ulcerative colitis, Crohn's disease, chronic active hepatitis, chronic relapsing(More)
Studies have shown the levels of free serotonin in plasma are increased in symptomatic patients with asthma. In addition, the concentration of free serotonin in symptomatic children with asthma correlates positively with clinical status and negatively with pulmonary function (forced expiratory volume in 1 second [FEV1]). Thus, reducing the concentration of(More)
Studies have shown that levels of free serotonin in plasma are increased in symptomatic patients with asthma. In addition, the concentration of free serotonin in symptomatic patients with asthma correlates positively with clinical status and negatively with pulmonary function. Thus, reducing the concentration of free serotonin in plasma might be useful in(More)
A 57-year-old white man presenting frequent recurrent chest and precordial pain, heartburn (pyrosis) and post-prandial vomiting for the previous 33 years (one to two years after Bilroth II gastrectomy) was submitted to cardiovascular, endoscopic, radiologic and biochemical studies with negative results. Doctors recommended surgical operation because of an(More)
Immunodeficiency is frequently invoked as an ethiopathogenetic factor for many somatic diseases. On the other hand, stress, depression, and psychotic disturbances are associated with severe immunological disorders. Taking into account that the benzodiazepines (BZ) are the psychoactive drugs more widely used than any other to treat psychological(More)
