Abstract

UNLABELLED

Colorectal cancer is a serious medical problem. According to one hypothesis of carcinogenesis, tumour creation process begins and develops when the balance between the production of reactive oxygen species (ROS) and their disactivation by the antioxidant protective barrier of the organism is disturbed. THE AIM OF THE STUDY was, following this theory, to examine the plasma concentration of the dietary minerals with antioxidant properties.

MATERIAL AND METHODS

The research material was the blood of 8 people, taken to vacuum test tubes with an anticoagulant - 4 ml of sodium heparin. The activity of catalase was marked following Beers method, while the activity of superoxide dismutase according to H.P. Misra and J. Fridovich method.

RESULTS

The results show that the copper complex added, i.e. dichlorine(3,4,5-trimethyl-N1 - pyrazol-1yl) Cu(II) from derivatives of azoles, has a large impact on the activity of selected enzymes. After adding it, their activity increased by ca 67% in comparison with the control group. It proves the efficacy of this compound.

CONCLUSIONS

The results prove the free radicals theory of carcinogenesis. They also confirm the part which the antioxidant protective barrier plays in the defense against ROS and their carcinogenic consequences.

摘要

未标注

结直肠癌是一个严重的医学问题。根据一种致癌假说,当活性氧(ROS)的产生与机体抗氧化保护屏障对其的失活之间的平衡被打破时,肿瘤形成过程开始并发展。本研究的目的是按照这一理论,检测具有抗氧化特性的膳食矿物质的血浆浓度。

材料与方法

研究材料为8人的血液,采集到含有抗凝剂(4毫升肝素钠)的真空试管中。过氧化氢酶的活性按照比尔斯法进行标记,而超氧化物歧化酶的活性按照H.P. 米斯拉和J. 弗里多维奇法进行测定。

结果

结果表明,所添加的铜络合物,即来自唑类衍生物的二氯(3,4,5 - 三甲基 - N1 - 吡唑 - 1基)铜(II),对所选酶的活性有很大影响。添加后,与对照组相比,它们的活性提高了约67%。这证明了该化合物的有效性。

结论

结果证明了致癌的自由基理论。它们还证实了抗氧化保护屏障在抵御ROS及其致癌后果中所起的作用。
