The main purpose of this study was to investigate the effect of thyroxine and PTU in ascitic Ehrlich tumor cells. Tumor was implanted in 30 female mice distributed in three groups: treated with PTU, treated with thyroxine and control. Each group received an intraperitoneal injection of neoplastic cells, pre-incubated with sterile solutions of PTU, thyroxine and distilled water, respectively. On the fifth and seventh days after inoculation, animals received an intraperitoneal injection of the respective solutions. On the tenth day after inoculation, animals were sacrificed. Volume of ascitic liquid, number of neoplastic cells/ml and percentage of viable cells were determined. Ascitic liquid smears were carried out for tumor cytological evaluation. There was...

Kint3-4 promotes apoptosis and inhibition of angiogenesis in solid Ehrlich Tumor
Provedor de dados: 45
Autores: Souza,C; Carvalho,L.F.; Ferreira,M.A.N.D; Pesquero,J.L.; Cassali,G.D.
A proteína Kint3-4 (PKint3-4), codificadora da angiostatina, é reconhecida por sua potencialidade antiangiogênica. O presente estudo teve como objetivo avaliar o efeito da proteína Kint3-4 no crescimento do tumor sólido de Ehrlich. Para isso, foram analisados a curva de desenvolvimento tumoral, o índice apoptótico e a dosagem de hemoglobina, a fim de se avaliar a angiogênese, em 20 camundongos Swiss fêmeas, inoculadas com o tumor sólido de Ehrlich em seus coxins plantares. Os resultados demonstraram a participação de PKint3-4 na indução à apoptose de células neoplásicas, na diminuição da concentração de hemoglobina e, principalmente, na diminuição do desenvolvimento tumoral. Sugere-se que a ação antitumoral, determinada pela sequência proteica utilizada,...

Mimosine and cyclophosphamide: a potential new combination therapy used to prevent tumor development
Provedor de dados: 52
Autores: Dipe,Vânius Vinícius; Gotardo,André Tadeu; Haraguchi,Mitsue; Górniak,Silvana Lima.
The effects of mimosine (MI), which is an amino acid that is derived from Leucaena leucocephala, were evaluated on the growth of ascitic Ehrlich tumors, and the effects of the combination treatment of MI and cyclophosphamide (CY) on tumor growth were also assessed. Mice were divided into groups that received the following treatments over the course of 20 days: phosphate buffer solution (CO), MI, Ehrlich cells (E), E plus CY (EC), E plus MI (EM) and E plus MI and CY (EMC). No signs of toxicity were detected in the mice from the MI group. The mice from the EMC group showed reductions in body weights when compared with those from the E group. The animals from the EC, EM and EMC groups showed reductions in ascitic volume compared with those from the E group....

The effect of phosphoethanolamine intake on mortality and macrophage activity in mice with solid ehrlich tumors

The aim of the present study was to examine the effect of a diet rich in synthetic PEtn on the metabolism macrophages of tumor-bearing mice. The results demonstrated that PEtn increased the animals' survival time. In addition, the treated animals released smaller amounts of hydrogen peroxide (H2O2) and nitric oxide (NO) than the non-treated animals, particularly after day 14. From the results it could be concluded that H2O2 and NO were important in the modulation of neoplastic growth, and pointed to a promising role of PEtn in the control of human neoplasms.

Effect of cyhalothrin on Ehrlich tumor growth and macrophage activity in mice
Provedor de dados: 56
Autores: Quinteiro-Filho,W.M.; Righi,D.A.; Palermo-Neto,J.
Cyhalothrin, a pyrethroid insecticide, induces stress-like symptoms, increases c-fos immunoreactivity in the paraventricular nucleus of the hypothalamus, and decreases innate immune responses in laboratory animals. Macrophages are key elements in cellular immune responses and operate at the tumor-host interface. This study investigated the relationship among cyhalothrin effects on Ehrlich tumor growth, serum corticosterone levels and peritoneal macrophage activity in mice. Three experiments were done with 10 experimental (single gavage administration of 3.0 mg/kg cyhalothrin daily for 7 days) and 10 control (single gavage administration of 1.0 mL/kg vehicle of cyhalothrin preparation daily for 7 days) isogenic BALB/c mice in each experiment. Cyhalothrin i)...
