The effects of phorbol ether (PMA) and ionizing radiation on multidrug resistance (MDR) of human larynx cancer cells HEp-2 and the dependences of these effects on protein kinase C (PKC) activity and reactive oxygen species (ROS) production were studi

The influence of different exposure regimes of low-intensity extremely high-frequency electromagnetic radiation on the growth rate of solid Ehrlich carcinoma in mice has been studied. It was shown that, at an optimum repetition factor of exposure (20

We studied the effect of gamma-radiation on 15-lipoxygenase activity in rat thymocytes. The enzyme activity was determined as the rate of linoleic acid oxidation by the protein fraction isolated from the control and irradiated thymocytes under standa

We studied the effect of specific inhibitors of 5- and 12-lipoxygenases as well as the product of cyclooxygenase activity, prostaglandin E2, on proliferation and death of P388 leukemia cells. Inhibition of 5- and 12-lipoxygenases in the cells inhibit

The radiation-induced apoptosis of thymocytes is suppressed by the common inhibitor of lipoxygenases nordihydroguaiaretic acid but not the inhibitors of cyclooxygenases or cytochrome P-450, which indicates the key role of lipoxygenases in apoptosis.

We studied the effect of oxidative stress induced by hyperoxia, hydrogen peroxide, or menadione on mouse leukemia P388 cells at early (4 days) and late (7 days) stages of tumor growth. Oxidative stress proved to inhibit cell division and to induce ap

The combined effect of ionizing radiation (0.5-4 Gy) and the vitamin B12-C complex on life-span of mice with Ehrlich carcinomas was studied. It was shown that antitumor effect of the combined treatment strictly depends on the sequence of the agent ap

We studied the effect of arachidonic acid metabolism inhibitors in a wide concentration range on the proliferation and death of lympholeukemia cells P-388. Proliferation of the cells was estimated by metaphase frequency and the proportion of cells in

Effect of natural avermectin complex (aversectin C) and separate avermectins A1, A2, B1 and B2 in the cell culture of murine myeloma Ns/o, Erlich carcinoma ascites and human larynx carcinoma Hep-2 was investigated. It was shown that aversectin C with

Avermectins are final products in the fermentation process with Streptomyces avermitilis. They have parasitocidic activity and are used as the main substances of insectoacaronematocides. The study of the activity of the natural avermectin complex (av
