Kuligowski D: [The influence of chronic exposure to carbon disulfide on metabolism of catecholamines and serotonin in women]. Am J Ind Med. 1990;17(2):247-54.
Due to more frequent occurrence of the idiopathic arterial hypertension of borderline type (18.97% of screened women), with values varying from 18.7/12.0 to 21.3/12.7 kPa (140/90-160/95 mm Hg), in women chronically exposed to carbon disulfide as compared to the control group (8.5% women), we decided to investigate the activity of sympathetic-adrenal nad serotoninergic systems that play an important role in the haemostasis of cardiovascular system. The aim of the presented study is to evaluate the linear correlation between: 1) serum dopamine-beta hydroxylase activity and the dopamine concentration in plasma as well as 24-hours adrenaline and noradrenaline excretion in the urine; and 2) between catechol-0-methyltransferase and monoaminoxidase activity and the 24-hours excretion of catecholamine in the urine; next the serum and platelet concentration of serotonin and the arterial blood pressure in women chronically exposed to carbon disulfide. The investigations were performed on 140 women, aged 22 to 55, who were divided into two groups: group-I the control group, covered 50 women employed in the Industrial Clothing Factory "Dana" in Szczecin. Group II-the study group, consisted of women employed in the Synthetic Fibres Factory "Wiskord" in Szczecin-Zydowce, in the carbon disulfide (CS2) atmosphere in concentration from 9.36 to 23.4 mg/m3. The microclimate conditions of the production halls in both groups were similar (Tab. 1). It has been observed that in women chronically exposed to CS2 plasma dopamine concentration (p < 0.001) and DBH serum activity (p < 0.001) are significantly lower as compared to the control group parameters (Tab. 2). Also dopamine concentration and DBH activity are lower in all subgroups of women exposed to CS2 (Tab. 3). In women working in the CS2 atmosphere, 24-hours excretion of adrenaline is significantly lower (p < 0.001) as compared to the control group. Parameters for 24-hours noradrenaline and VMA excretion in the urine do not show any statistical significance (Tab. 4). Plasma (p < 0.001) and platelet (p < 0.001) concentration of serotonin is significantly higher in women exposed to CS2. However, 24-hours 5-HIAA excretion in the urine in women of group II is higher than in group I, but does not give evidence of any statistical significance (Tab. 6). Both serum (p < 0.001) and platelet (p < 0.001) MAO activity is significantly lower in women chronically exposed to CS2. Also COMT erythrocyte activity is significantly lower (p < 0.001) in the studied group women (Tab. 8). The women working in the CS2 evaporation display significantly higher serum concentration of total (p < 0.001), bound (p < 0.001) and free (p < 0.001) tryptophane (Tab. 9). In women exposed to CS2, serum concentration of zinc (p < 0.001) and copper ions (p < 0.001) is significantly lower (Tab. 10). In comparison to the control group parameters, the women exposed to CS2 claim values of systolic and diastolic arterial blood pressure being insignificantly higher. However, in women working in CS2 atmosphere the coefficients of linear correlation between plasma (r = 0.59; p < 0.001) and platelet (r = 0.73; p < 0.001) serotonin concentration and the systolic arterial blood pressure, as well as plasma (r = 0.065; p < 0.001) and platelet (r = 0.72; p < 0.001) serotonin concentration and the diastolic arterial blood pressure are significantly higher (Tab. 11). Significantly positive linear correlation between serotonin concentration and arterial blood pressure in women chronically exposed to CS2 may suggest the important role of this amine in the pathogenesis of arterial hypertension. |
