摘要

研究了饲粮中添加白藜芦醇、染料木素和槲皮素对蛋白质、脂质和核酸氧化损伤的相关性。此外,还评估了7,8-二甲基苯[a]蒽(DMBA)引起的致癌变化的形成速率。还介绍了所选多酚类化合物对dba诱导的致癌强度的影响结果。所使用的多酚,即白藜芦醇、染料木素和槲皮素,通过与它们的抗氧化性能、菜籽油中DMBA和脂肪酸的影响以及癌症过程的进展阶段相关的选定生物标志物的浓度进行测量,也很重要。研究了所选多酚类化合物对7,8-二甲基苯[a]蒽诱导的大鼠癌变强度和对蛋白质、脂质和核酸的氧化损伤的影响。确定选定剂量和不同混悬液中多酚活性的结果,可能允许将这些膳食化合物应用于人类癌症预防或改善药物治疗。

THE EFFECT OF POLYPHENOLS ON MARKERS OF OXIDATIVE DAMAGE AND DMBA-INDUCED CARCINOGENESIS IN RATS

ABSTRACT

The correlation between diets supplemented with resveratrol, genistein or quercetin on oxidative damage to proteins, lipids and nucleic acids was examined. Moreover, the rate of formation of changes resulting from carcinogenesis induced by 7,8-dimethylbenz[a]anthracene (DMBA) was assessed. The results for the impact of selected polyphenolic compounds on the intensity of DMBA-induced carcinogenesis were also presented. The polyphenols used, namely resveratrol, genistein and quercetin measured by the concentration of selected biomarkers related to their antioxidant properties and the impact of DMBA and fatty acids in rapeseed oil as well as of progression stage of the cancer process, were also significant.

PRACTICAL APPLICATIONS

The estimation of the impact of selected polyphenolic compounds on the intensity of 7,8-dimethylbenz[a]anthracene-induced carcinogenesis and oxidative damage to proteins, lipids and nucleic acids in rats was examined. Identifying the results of polyphenol activity in selected doses and different suspensions may allow application of these dietary compounds in human cancer prevention or for improvement of pharmacological treatment.
