摘　　要：[目的 ]评价锰接触对作业工人心血管系统自主神经功能的影响。 [方法 ]采用EwingDJ推荐的自主神经功能测试组合对 5 6名电焊工人和 3 4名正常对照工人进行了测试 ,测试项目共包括ValaslvaManoeuvre心率反应 (HR V)、深呼吸时的心率变化 (HR DB)、即立心率反应 (HR IS)和即立血压反应 (BP IS)。 [结果 ]电焊工人的血锰值 (0 0 88± 0 0 5 8)μmol/L明显高于对照组 (0 0 2 7± 0 0 2 2 ) μmol/L ,HR V (1 43± 0 2 3 )、HR DB(15 98± 6 0 6)以及即立时R R变化能力Rmax∶min(1 2 4± 0 14 )均明显低于对照组。多元逐步回归分析表明年龄、接触锰的年数、饮酒、受教育年数从不同方面影响心率和血压变化。 [结论 ]锰作业工人的副交感神经调节功能降低 。To evaluate the adverse effect of manganese exposure on workers cardiovascular autonomic nervous system . Autonomic nervous system function test battery recommended by Ewing DJ was conducted in 56 manganese exposed workers selected from a machine building plant and 34 healthy reference people come from a flour factory. Blood Mn concentration in welding workers (0 088±0 058 μmol/L) was significantly higher than that in control group (0 027±0 022 μmol/L). HR V (1 43±0 23),HR DB (15 98±6 06) and R max∶min (1 24±0 14) decreased in manganese exposed group compared with those of control group. Multiply regression analysis indicated that age,manganese exposure duration,alcohol drinking and education duration affect heart rate and blood pressure. [Conclusion] The result inferred that manganese may have adverse effect on parasympathetic nerve . Cardiovascular autonomic nervous system is likely a target system of manganese detriment.
