Induced Changes

To determine whether reactive oxygen molecules could directly and reversibly increase the transfer of albumin across an endothelial barrier, we measured albumin transfer across monolayers of endothelium cultured on micropore filters before and after exposure to xanthine and xanthine oxidase. Xanthine and xanthine oxidase increased endothelial albumin transfer in a dose-dependent fashion. Parallel phase contrast and fluorescence microscopy demonstrated retraction of adjacent cells from one another and disruption of the actin filaments. The oxidant- induced increases in albumin transfer and changes in cell shape were reversed by removing xanthine oxidase and then incubating the monolayers for 3 1/2 hours in tissue culture media enriched with fetal bovine serum. However, incubation in tissue culture media without serum resulted in progressive injury and cell death. Hence, the brief exposure to oxidants initiated a progressive injury process that was reversed by incubation in serum. Because intracellular and extracellular calcium are important determinants of cell shape, and because some oxidized membrane lipids act as calcium ionophores, we asked whether oxidants altered endothelial calcium homeostasis. Xanthine-xanthine oxidase increased release of 45Ca++ from preloaded cells. The calcium antagonist lanthanum chloride prevented xanthine- xanthine oxidase increases in endothelial albumin transfer and prevented the changes in cell shape; chelation of extracellular calcium inhibited lysis of endothelium by xanthine-xanthine oxidase; and the calcium ionophore A23187 increased endothelial albumin transfer and mimicked the oxidant-induced changes in cell shape. Lanthanum chloride inhibited these effects of A23187. These data suggest that oxygen radicals can reversibly increase endothelial permeability to macromolecules, that this is associated with reversible changes in endothelial cell shape and actin filaments, and that the changes in cell shape are related to oxidant-induced changes in endothelial calcium homeostasis.

Fibroblast Transformation

The rat embryo fibroblast focus assay is used to evaluate the transforming potential of several oncogenes. The sensitivity of this assay increased fivefold when retinoic acid was added to tissue culture media. Retinoic acid probably acts by selectively inhibiting the proliferation of nontransformed cells.

History Of

Thirteen communities from 7 Argentinian provinces were selected for the evaluation of serology as an indicator of transmission of Chagas disease. Of the communities appraised, 6 did not have a history of previous treatment with insecticides and 7 had received sporadic or continuous insecticide treatment. The inhabitants of 20% of the houses of each locality were studied by serology. The samples were obtained byfinger pricking and 50 fil of blood were mixed with 150μl of 50% glycerine solution in tissue culture media to be assayed by Indirect Hemagglutination and Indirect Immunofluorescence tests. In untreated areas, the prevalence of infection in infants 0-4 years old was 17.5%, reaching to over 22% for the 5-9 year old group, and to 33.3% in 10-14 year old individuals. The prevalence in treated and surveyed areas was 2.6% in 0-4 year old children, 5.4% in 5-9 year old and 6,2% in 10-14 year old youngsters. The differences between both areas were statistically significant (p < 0.005). This study favors serology as a valid indicator for the evaluation of transmission of Chagas disease in rural areas.

Growth Quality

One of the problems in plaintain development is on the plant breeding that has been conducted convensionally by using seedlings, so that it requires time and wide field, different treatment, and potentially brings pests and deseases. The bean sprout extract is potentially useful in improving the explant growth quality of plaintain by tissue culture. This study aims to know the influence of bean sprout extract concentration as supplement in tissue culture media upon the explant growth of plaintain Unti sayang (Musa paradisiaca L). There are 4 dosages of bean sprout extract as control. The data was analyzed by using ANOVA and was continued by using BNJ test. The result of the experiment shows that the bean sprout extract influences significatly on the plantlets height, leaf number, root length, and root number. The dosage of 100 g/l and 200 g/l bean sprout extracts provide the best result on the experimenting component of plantlet height, leaf number, root length, and root number. Meanwhile, the experimenting component of leaf number and the wet weight of the plantlets provide the best result on MS without any addition of bean sprout extract.
