Plasma and Urinary Catecholamine Concentrations in Patients with Vibration Syndrome Before and After Hospital Treatment
研究了35名振动综合征患者住院治疗前后血浆和尿中儿茶酚胺浓度、皮肤温度及冷刺激后恢复率的变化，发现治疗后儿茶酚胺浓度下降、手部血液循环改善。
For 23 male and 12 female patients with vibration syndrome the plasma and urinary catecholamine concentrations, the skin temperature, the effects of the nail compression test at room temperature, and the recovery rates of the skin temperature and nail compression test after cold provocation were investigated before and after hospital treatment. The aim was to evaluate the effect of five weeks' hospital treatment on the autonomic nervous balance of patients with vibration syndrome. The plasma norepinephrine concentration tended to decrease in the female patients after the treatment. A decrease in the plasma epinephrine concentration and in the variation between the plasma epinephrine levels during the day were found after the treatment. The total urinary dopamine concentration decreased significantly in the patients after the treatment. The recovery rates of the skin temperature after the cold provocation showed a tendency to increase after the treatment. These results suggest an improvement in the blood circulation of the subjects' hands. The decreases in catecholamine concentration and the variation in the epinephrine levels may have played a role in the improvement of the blood circulation of the patients after the treatment.
