| [immunogenicity of l5178y cells modified by different reagents]. | lymphoma l5178y cells were treated with neuraminidase of vibrio cholerae, potassium iodine, dithiotreitol (dtt), mercaptoethanol, glutaraldehyde, iodoacetamide, merthiolate, sodium periodate, urea, papaine, trypsine and edta, to increase immunoreaction in tumor cells. mice were immunized with modified tumor cells every week for one month. thereafter non modified tumor cells were transplanted to previously immunized mice. only the immunization with neuraminidase-treated cells rejected the tumor. ... | 1977 | 410377 |
| application of the indirect enzyme-labeled antibody microtest to the detection and surveillance of animal diseases. | the rapid, indirect enzyme-labeled antibody (ela) microplate test has been developed as a diagnostic and surveillance tool to aid in the control of animal disease. the test has been applied to viral (hog cholera), parasitic (trichinosis), and bacterial (brucellosis) diseases of animals. a correlation of greater than 95% was observed between the hog cholera ela test and the serum neutralization test for hog cholera in greater than 2,000 field samples obtained during the 1976 epizootic in new jers ... | 1977 | 409789 |
| detection and differentiation of iron-responsive avirulent mutants on congo red agar. | agar medium containing congo red dye differentiates virulent and avirulent colonies of shigella, vibrio cholerae, escherichia coli, and neisseria meningitidis. like virulent plague bacilli, wild-type cells of these species absorb the dye and produce red colonies. mutants or colonial variants have been isolated that fail to absorb the dye and produce colorless colonies. these mutants exhibit reduced virulence in the chicken embryo model, but their virulence is enhanced by supplementation with iro ... | 1977 | 409688 |
| tissue reactions to long-term electrical stimulation of the cerebellum in monkeys. | light and electron microscopic analyses were carried out on the stimulated and unstimulated paravermal cortices of six rhesus monkeys that had electrodes implanted on their cerebella for 2 months. the electrodes and the stimulation regime (10 p.p.s.: 8 min on, 8 min off) were similar to those used to stimulate the human cerebellum for treatment of certain neurological disorders. mere presence of the electrode array in the posterior fossa for 2 months resulted in some meningeal thickening, attenu ... | 1977 | 408468 |
