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 ...

1. Extracts of Landschutz ascites-tumour cells have been fractionated by treatment with acid, alumina C(gamma) gel and Sephadex G-100 to yield purified preparations of thymidine phosphokinase, thymidine 5'-monophosphate phosphokinase and thymidine 5'-diphosphate phosphokinase. 2. These results clearly demonstrate the existence in Landschutz ascites tumour of three phosphokinases each of which ...

Bekierkunst, Adam (Bryn Mawr College, Bryn Mawr, Pa.), and L. Joe Berry. Cytotoxic effect of mycobacteria on Ehrlich ascites cells. J. Bacteriol. 89:205-211. 1965.-Mycobacterium tuberculosis, strains H(37)Rv, H(37)Ra, and BCG, release into a medium within 3 to 5 hr a substance that is toxic to Ehrlich ascites cells as evidenced ...

Peritoneal exudate cells from animals exhibiting delayed hypersensitivity are inhibited from migrating in vitro by specific antigen. This inhibition is completely abolished by pretreatment of the sensitive cells with trypsin. The action of trypsin is prevented by soybean trypsin inhibitor. The results of experiments with mixtures of normal and sensitive ...

Following extraperiosteal injections of saline, serum, or whole blood, the synthesis of DNA in the cells of the osteogenic layer of the femora of mice was stimulated to approximately two-thirds of the level obtained by fracture of the femora. Irrespective of the material injected, the proliferative response of the cells ...

The standard The standard procedures Glucostat method and Fiske-Subbarowphosphorus determination-are inadequate for the assay of glucose-6-phosphatase activity in Ehrlich ascites cells. Therefore, RNA induction of this enzyme in ascites cells, even if it occurs, cannot be demonstrated by thefe procedures.

Acatalasia, a disease due to homozygosity for a Mendelian gene, is characterized by the absence of the enzyme catalase from the tissues of the human body. Red cells from heterozygotes have enzyme activities about one-half normal. In this paper, the development of cell lines from skin biopsies on an affected ...

When malignant cells, animal and human, were exposed in vitro to solutions of heavy metals or other selected compounds, three types of cell blebs were produced: (1) acentric blebs, arising from one side of the cell, e. g., by chlormerodrin, meralluride sodium, mercuric chloride; (2) symmetrical blebs; which completely enveloped ...

Heat-killed cells of Group A streptococci caused death of the adrenalectomized rat. While the adrenalectomized rat readily succumbed to intraperitoneal infection with living cells, death was due primarily to toxicity. The normal rat was highly resistant under either condition. For studies on the toxic materials, the cells of numerous serological ...

It has long been known that fat accumulates in old injured cells both in tissue culture and in many mammalian disease states. The use of L cells grown in suspension tissue culture permitted the opportunity to study conditions in which lipide accumulation could be retarded or accelerated. These cultures exhibit ...

The activities of the enzymes arginase and rhodanese were examined in homogenates of 13 mouse cell strains and 2 human cell strains after long cultivation of the cells in vitro. Three strains of mouse liver origin showed both high arginase and rhodanese activities in keeping with activities of the tissue ...

The tumour cells and the reaction cells in Sarcoma 37 ascitic fluids have been studied in thin sections with the electron microscope. The reaction cells were either leucocytes or much larger acidophilic peritoneal cells of the same dimensions as the tumour cells; the peritoneal cells formed as much as 20 ...
