The immunological response of mice given implants of Ehrlich ascites carcinoma was modified as evidenced by the failure of ascitic mice to reject primary or secondary skin homografts or rat skin heterografts. The site of tumor implantation influenced its effect on the host, since subcutaneously implanted Ehrlich ascites carcinoma did not alter the immune response. The presence of the tumor in t...

Diversas espécies do gênero Solanum apresentam glicoalcalóides e flavonóides com grande variedade de atividades biológicas. O flavonóide tiliroside (1), uma fração rica em glicoalcalóides denominada GB e o glicoalcalóide solasonina (2) foram obtidos dos tricomas de galhos jovens e frutos de Solanum crinitum Lam e o alcalóide estereoidal solasodina (3), extraído das partes aéreas de S. jabrense ...

Six different extracts from Eucalyptus citriodora leaves were investigated for their anticancer effect. Extracts were prepared using a range of polar and non-polar solvents to leach out maximum active components. Phytochemical analysis of the extracts revealed the presence of anthraquinones, cardiac glycosides, flavonoids, saponins and tannins. Cytotoxic activity of different extracts was teste...

phenyl phenanthridinium bromide) has been shown to inhibit completely the incorporation of preformed purines into the nucleic acids of Ehrlich ascites carcinoma cells, but the drug does not ap preciably inhibit the incorporation of radioactive glycine into nucleic acids or proteins (4). These studies have been interpreted in terms of disrup tion of the normal relationship between intracellu lar...

The present study examines the therapeutic efficacy of the administration of low-dose cisplatin (cis) followed by exposure to extremely low-frequency magnetic field (ELF-MF), with an average intensity of 10 mT, on Ehrlich carcinoma in vivo. The cytotoxic and genotoxic actions of this combination were studied using comet assay, mitotic index (MI), and the induction of micronucleus (MN). Moreover...
