选择了高温、ＣＯ、高温与ＣＯ和无任何职业有害因素接触的作业工人分别作为高温组、ＣＯ组、高温与ＣＯ组和对照组。从每组中选出年龄在４０～４２周岁，工龄在２１～２２年的健康男性工人各５名分析血浆中游离氨基酸含量。结果如下：（１）在必需氨基酸中，ＨＳＰ７０蛋白质中含量较少的蛋氨酸、色氨酸，其血浆中游离的这两种氨基酸浓度明显高于对照组（Ｐ＜０．０５），其中色氨酸以高温＋ＣＯ组高，蛋氨酸以高温组最高。在ＨＳＰ７０含量较多的赖氨酸、缬氨酸中，其四组间无显著性差异（Ｐ＞０．０５）。（２）在非必需氨基酸中，与对照组相比，大多趋向增高。本调查结果提示了接触高温、ＣＯ工人所面临的关键问题是如何促进氨基酸的利用和减轻应激时正常蛋白合成的抑制。
Selected high temperature, CO, high temperature and CO and occupational hazards without occupational exposure workers were as high temperature group, CO group, high temperature and CO group and control group. From each group, five healthy male workers aged 40-42 years and 21-22 years of age were selected to analyze free amino acids in plasma. The results were as follows: (1) Among the essential amino acids, methionine and tryptophan were lower in HSP70 protein than those in control group (P <0.05) Acid to high temperature + CO group, methionine highest in the high temperature group. In the lysine and valine with more HSP70, there was no significant difference among the four groups (P> 0.05). (2) Among the non-essential amino acids, most of them tend to be higher than the control group. The results of this survey suggest that high exposure to high temperatures, CO workers are the key issues facing how to promote the use of amino acids and reduce the inhibition of stress normal protein synthesis.
