Benzopyrene (B(a)P) and coal-tar pitch (CTP) are one of the important factors of enhancing incidence and mortality in the taroperating population with professional lung cancer.The transformation system of cell in vitro was used in this studies. The per-carcinogenic changes of the human embryo lung cell (HEL-9201) in vitro exposed to final concentration of lμg/ml B (a) P or CTP, respectively , and protective effect of Se (1×10-5mol/ml) on cell transformation were observed.

Benzopyrene (B(a)P) and coal-tar pitch (CTP) are one of the important factors of enhancing incidence and mortality in the taroperating population with professional lung cancer.The transformation system of cell in vitro was used in this studies. The per-carcinogenic changes of the human embryo lung cell (HEL-9201) in vitro exposed to final concentration of lμg/ml B (a) P or CTP, respectively , and protective effect of Se (1×10-5mol/ml) on cell transformation were observed. The results shown that the characteristics of morphological transformation of HEL-9201 cells were exhibited after treatment 11th to 12th passages by B (a)P or CTP, for contract with Se treated group. The Se protective group cells havn't the characteristics of transformation, it was reduced for chromosome injury. The protective efficiency of Se on B(a)P and CTP were 62.9% and 58.0% , respectively. The results suggest that the Se is better an agent to prevent earcinogenesis.

B(a)P和CTP是煤焦化作业人群中职业性肺癌发病率与死亡率增高的重要因素。本研究应用体外细胞转化模型,观察了微量元素硒(Se)对B(a)P和CTP诱发人胚肺细胞癌前变化的保护作用。结果表明,人胚肺细胞分别经终浓度B(a)P和CTP为1.0μg/ml处理之前30分钟经Se终浓度为1.0×10-5M/ml预先保护后,分别进行体外传代至第12~13代时,出现形态学转化特征,与Se防护组比较,转化程度减轻,或不发生转化,染色体损伤减轻,其防护效率分别为62.9±13.7%和58.0±17.0%,提示Se对B(a)P和CTP具有较好的防癌效果。

The biochemistry and genetic indexes of oven workers were measured.The results showed that serum carotene, blood Se and hair Se were not affected.It was suggested that lung cancer excess among the oven workers isn′t related to Se insufficiency.Lymphocyte transformation incidence,lymphocyte micronucleus incidence,lymphocyte chromosome aberration increased (P<0.01).The lymphocyte chromosome aberration incidence can be useful as a sensetive genotoxicity indicator for oven workers.

本研究通过对炼焦作业工人的血硒、发硒、外周血淋巴细胞微核以及染色体畸变等生化、遗传指标的分析表明:炼焦作业工人血硒、发硒与对照比较未见明显异常(P>0.05),提示焦化作业工人肺癌的高发与机体内硒的缺乏无必然联系。焦炉工人外周血淋巴细胞微核率,染色体畸变率均增高,由此说明炼焦生产可产生某些致突变物质,这些物质可能与焦炉工人癌症高发有一定联系。故应加强对染色体畸变率明显增高人群的监护。

The effect of coal tar pitch(CTP)on glutathione per oxidase(GSH-Px)had been studied with experimental rats and among workers who exposed occupationally to CTP of 20mg,40mg CTP powder suspended in 0.2ml sterile saline solution was intratracheally injected in to each rat, respectively. After forty days,the blood GSH-Px activity decreased obviously.Sixty days later, the blood GSH-Px activity declined very significantly, and the GSH-Px activity of kidney decreased obviously(P<0.05 ),but the GSH-Px activity of liver...

The effect of coal tar pitch(CTP)on glutathione per oxidase(GSH-Px)had been studied with experimental rats and among workers who exposed occupationally to CTP of 20mg,40mg CTP powder suspended in 0.2ml sterile saline solution was intratracheally injected in to each rat, respectively. After forty days,the blood GSH-Px activity decreased obviously.Sixty days later, the blood GSH-Px activity declined very significantly, and the GSH-Px activity of kidney decreased obviously(P<0.05 ),but the GSH-Px activity of liver made no change. The GSH-Px activity of kidney after sixty days in 40mg dose group decreased more significantly than that in 20mg dose group(P<0.05).The blood GSH-Px activity in coking workers was significantly lower than that in controls(P<0.01). The results showed that CTP could decreased blood GSHPx activity and enhanced 63 the level of lipid peroxidation.

向大白鼠气管内分别一次性注入20、40mg煤焦沥青(CTP),40天后大白鼠全血谷胱甘肽过氧化物酶(GSH-Px)活性显著下降,60天后下降更明显。肾GSH-Px活性也显著下降,40mg剂量组较20mg剂量组下降更明显(P<0.05),但肝GSH-Px活性无明显变化。焦化作业工人全血GSH-Px活性显著低于对照组(P<0.001),且随工龄增加而下降(P<0.05)。结果表明CTP可降低GSH-Px活性,使机体脂质过氧化作用增强
