[Antitoxic and antioxidant effects of N-stearoylethanolamin in the content of nanocomposite complex with doxorubicin in organs of mice with Lewis carcinoma].

The aim of the study was to evaluate the possibility to reduce the doxorubicin toxic effects by its immobilization with N-stearoylethanolamine (NSE) on nanocarier polyethylene glycol. The studied parameters of the doxorubicin toxicity were: the level of creatinine in the mice blood plasma and activity of alanine aminotransferase and aspartate aminotransferase in the blood plasma of mice. The activity of catalase superoxide dismutase, glutathione peroxidase and intensity of lipid peroxidation was determined in the tissues of the heart, kidneys and liver.

[Organ-specific antitoxic effects of N-stearoylethanolamine in male mice with Lewis carcinoma under doxorubicin intoxication].

With the introduction of doxorubicin into mice with Lewis carcinoma in the heart and liver tissues and kidney the organ-antitoxic effects of N-stearoilethanolamine (NSE) were found, which depended on its concentration. Administration of doxorubicin to male mice leads to an increase in the level of urea and creatinine, as well as activation of ALT in blood plasma. Introduction of NSE resulted in normalization of these parameters to the level of intact animals.

[Protective effect of N-stearoylethanolamine in suspension and in nanocomposite complex in the organs of mice with the Lewis carcinoma under doxorubicin intoxication administration].

The antioxidant effects of N-stearoylethanolamine (NSE) in the nanocomplex composition and in suspension are shown on the model of intoxication by doxorubicin in conditions of development of the Lewis carcinoma in the heart, kidneys and liver tissue and in the blood plasma of female mice. The NSE suspension reduces the level of urea in the blood plasma of mice with the Lewis carcinoma, which growth was revealed as a result of introduction of doxorubicin. Under introduction of nanocomplex the amount of urea remains at the level of that in the intact mice.

[Antioxidative effect of the N-stearoylethanolamine in the heart tissue and blood plasma of rats under doxorubicin treatment].

The influence of N-stearoylethanolamine on the alterated antioxidant enzyme activity in the heart tissue and blood plasma of rats under the doxorubicin treatment was investigated. It was shown that doxorubicin administration caused the decrease of antioxidant enzymes activity (superoxide dismutase and glutathione peroxidase) in the heart tissue. Administration of the NSE promoted the partial normalization of these enzymes activity.
