| 摘 要： | 为了观察青石棉、苯并（ａ）芘染尘大鼠血中超氧化物歧化酶（ＳＯＤ）和脂质过氧化物（ＬＰＯ）的变化，以探讨其致癌机制，用气管内染尘法，在染尘后９０，１８０，２７０，３６０和５４０天时观察大鼠ＳＯＤ、ＬＰＯ及ＳＯＤ／ＬＰＯ比值的变化，采用方差分析处理数据。结果提示，青石棉、苯并（ａ）芘可致ＳＯＤ活性降低、ＬＰＯ含量升高、ＳＯＤ／ＬＰＯ比值降低的趋势。表明体内抗氧化和脂嵵使趸胶馐У鳌

| Abstract: | To explore the mechanism of carcinogenicity of crocidolite and benzo (a) pyrene , wis- tar rats were divided into 4 groups at random for exposure , that were Cro. group. B (a ) p group , Cro. plus B(a)p group and control group. Samples of blood were collected in 90 , l80 , 270 , 360 and 540 days after the third time of intratracheal injection , and the SOD activity and LPO level were measured , the statistics method was F test. The results indicated the Cro. or B(a)p could de- crease the activity of SOD and increase the level of LPO , that suggesting the imbalance of antioxi- dation and oxidation by Cro. B(a)p in organisms. |
