[Use of WOBE-MUGOS E for prevention and correction of experimental doxorubicin side-effects]. / Ispol'zovanie VOBE-MUGOS E dlia profilaktiki i korrektsii pobochnykh reaktsii doksorubitsina gidrokhlorida v éksperimente.

Examined in treating rats with Guerin's carcinoma with doxorubicin was the possibility that the polyenzymic drug preparation wobe-mugos E had hepatoprotective, cardioprotective and myeloprotective effects. In intramuscular administration wobe-mugos E has not been found to stimulate the tumour growth, it exhibited a manifest hepatoprotective and myeloprotective actions with respect to adverse reactions of doxorubicin but failed to diminish cardiotoxicity of the latter. The protective effect of the above polyenzymic drug was of a dose-dependent character.

[Influence of tumor drug resistance phenotype on the dynamics of cisplatin-induced changes of rat peripheral lymphocyte chromatin structure in Guerin's carcinoma]. / Vliianie fenotipa lekarstvennoi rezistentnosti opukholi na dinamiku indutsirovann'ikh tsisplatinom izmenenii struktur'i khromatina interfazn'ikh iader limfotsitov perifericheskoi krovi kr'is s kartsinomoi gerena.

The correlation between the tumor drug sensitivity and the degree of lymphocyte interphase nuclei chromatin damages induced by cisplatin in rats was found using sensitive and resistant to cisplatin variants of Guerin's carcinoma. Increased optical density of lymphocyte chromatin in first minutes after cisplatin injection both in rats without Guerin's carcinoma and with sensitive to cisplatin variants of this tumor was observed. Lymphocyte chromatin structure remains unchanged in rats with cisplatin resistant carcinoma. Normal blood cells are suppose to change their sensitiveness to cisplatin under the humoral influence of the growing tumor in according with its phenotype.
