    Aim: To estimate the impact of C60 fullerene aqueous solution (C60FAS) on the rate of transplanted malignant tumor growth and metastasis. Methods: Lewis lung carcinoma was transplanted into С57Bl/6J male mice. Conventional methods for the evaluation of antitumor and antimetastatic effects have been used. Results: The C60FAS at low single therapeutic dose of 5 mg/kg inhibited the growth of transplanted malignant tumor (antitumor effect) and metastasis (antimetastatic effect): the maximum therapeutic effect was found to be of 76.5% for the tumor growth inhibition; the increase of animal life span by 22% was found; the metastasis inhibition index was estimated as 48%. Conclusion: It was found that water-soluble pristine С60 fullerenes efficiently inhibit the transplanted malignant tumor growth and metastasis.

  • Oxidative Stress in Chronic Obstructive Pulmonary Disease

    Oxidative Stress in Chronic Obstructive Pulmonary Disease

    , and 

    Chronic obstructive pulmonary disease (COPD) is a major worldwide health problem that has an increasing prevalence and mortality (12). Oxidative stress, which can be defined as an increased exposure to oxidants and/or decreased antioxidant capacities, is widely recognized as a central feature of many diseases (34). Considerable evidence now links COPD with increased oxidative stress (56). The purpose of this review is to describe the role and origin of the oxidant–antioxidantdisturbances that participate in the development of COPD. Our presentation also addresses ways of assessing the contribution of oxidants and identifies therapeutic approaches that could improve cellular oxidant–antioxidant balance in the lungs of COPD patients.
