[THE TOXIC EFFECTS OF CHEMOTHERAPY ON THE GASTROINTESTINAL TRACT].

Chemotherapy in modern oncology is one of the main methods of treatment, along with surgery and radiotherapy techniques. More than 60% of patients receiving chemotherapy at different stages of treatment. Recently, modern chemotherapy has become more urgent personal approach to the choice of drugs and their doses, aimed at reducing the toxicity of chemotherapy. Complications of chemotherapy significantly degrade the effectiveness of the treatment of patients with malignant tumors, because they require lower doses of anticancer drug, or lengthening the intervals between cycles of chemotherapy, which affects treatment outcomes and quality of life.

[Cardiotoxicity of conservative treatment of solid tumors].

With an increasing number of long-term breast cancer survivors, the number of patients experiencing anthracycline-induced cardiotoxicity increas too. Anthracycline--and nonanthracycline-induced cardiac toxicity--clinically significant and frequent adverse event of conservative treatment of cancer. Echocardiogram and multigated acquisition (MUGA) scan--modalities that may overlook early changes that could identify patients at risk for anthracycline-related cardiotoxicity. However, monitoring cardiac function before and during therapy, continuous infusions of drugs, limiting lifetime anthracycline dose, using cardioprotectants such as dexrazoxane, and developing lipid formulations, may decreased risk of cardiotoxicity.

[The efficacy of using low doses of immunomodulators for treating experimental tumors]. / Effektivnost' primeneniia malykh doz immunomoduliatorov dlia lecheniia éksperimental'nykh opukholei.

The data about the ability of various substances to cause definite reactions in biological objects are adduced, and, in particular, about the efficacy of a small doses of antitumoral chemopreparations in experiment. The results of investigation of the application efficacy of various doses of immunomodulating agents, such as arbisol, nucleoplat, the substrate from gram-negative bacteria Yersinia enterocolitica, antitumoral vaccine from the tumoral cells are presented for the cancer chemotherapy. While application of super-small doses of an antitumoral vaccine there was noted statistically significant inhibition of tumoral growth.

[Results and the prospects of use of the new chemical preparation polyplatillene with antineoplastic and antiviral properties]. / Rezul'taty i perspektivy primeneniia novogo khimiopreparata poliplatillena, obladaiushchego protivoopukholevymi i protivovirusnymi svoístvami.

Ten years experience of the polyplatillene clinical application and experimental study is summarized. Results of treatment of 689 inner organs cancer patients stage IV, I-IV clinical groups. The advantages of polyplatillene versus others platinum group chemopreparations are shown. Manufacturing difficulties, mistakes and perils of the preparation application are pointed out. The direct dose-dependence of results is shown. Possibilities of polyplatillene application in biotechnology, radiology, virusology as a regulator of the cell division, viral replication and their interaction with a cell is shown.
