Cytotoxicity of Some Edible Plants toward Ehrlich Ascites Carcinoma Cells

Effects of Ehrlich ascites antisera on the biochemical activities of Ehrlich ascites carcinoma cells in vitro.

Anl i-tumor sera are now being extensively used in investigations of the activities of neoplasms (e.g. 4-7, 9-13, 15). I t is already known (7), concerning their effects on the biochemical activities of tumors, that Ehrlich ascites carcinoma cells, treated with their antisera in the presence of comp]ement, lose their capacity to respire in the presence of glucose but not in the presence of succ...

Some abnormal permeability characteristics of Ehrlich ascites tumor cells.

Membrane Cholesterol Content and Malignancy of Ehrlich Ascites-Carcinoma Cells

If these three high-pH complications are corrected for, then the variation of kcat with pH in all three cases is governed by a single, non-essential ionization, around pH8.2 in the presence of Mg2+, and pH6 in its absence. It is tempting to equate this ionization with that obtained for conventional substrates [pH8.4 with Mg2+ and pH6.5 without (Tenu et al., 1971)], but, if the same species is r...

Transport and metabolism of thiamine in Ehrlich ascites-carcinoma cells.

1. Aerobic or anaerobic incubation at 37 degrees of Ehrlich ascites-carcinoma cells in Krebs-Ringer bicarbonate medium containing glucose and labelled thiamine results in accumulation in the cell of labelled thiamine, so that the concentration of total labelled thiamine in the cells greatly exceeds (by a factor 7) that in the medium. This concentration ratio is approximately constant for small ...

Inorganic ion concentrations in Ehrlich ascites carcinoma cells and fluid.

The concentrations of sodium, potassium, magnesium, cal cium, chloride, and phosphate were determined in Ehrlich ascites tumor cells and fluid after 5, 7, 9, and 12 days of growth. Material obtained after the 12th day showed peculiar intra cellular ion patterns, presumably related to the near-terminal condition. Material drawn after 5-9 days of growth represented viable cells. The intracellular...
