| epithelial or dandruff allergen for the diagnosis of dog allergy by rast? | when used for screening by the rast technique, dog epithelium provided too few positive results (29.2%) compared with dog dandruff (58.8%), cat epithelium (53.6%) and horse dandruff (52.2%). however, dog dandruff can provide an unexpectedly high incidence of positive rast results (45.2%) in sera from patients with an allergic history to cat or horse, but not to dog. dog dandruff allergens were found to cross-react with some cat or horse serum proteins in about 25% of such patients. we conclude t ... | 1979 | 115618 |

| mixed lymphocyte culture responses in combined immunodeficiency of horses. | combined immunodeficiency in horses is a genetic disorder in which there is a defect in the production of committed b and t lymphocytes. in this study, peripheral blood mononuclear leukocytes from foals with combined immunodeficiency were examined for their capacity to stimulate and respond in one-way mixed lymphocyte cultures. irradiated cells from combined immunodeficient foals were uniformly capable of stimulating cells from unrelated horses. however, none were able to respond to allogeneic s ... | 1978 | 146281 |
| inhibition of the mixed lymphocyte proliferative response by phorbol esters. | the phorbol diester, 12-o-tetradecanoyl-phorbol-13-acetate, a potent cocarcinogen in mice, blocks the induction of dna synthesis in lymphocytes undergoing the mixed lymphocyte response. at 10(-7) m diester, the induced dna synthesis is inhibited almost completely (99%). this action of the diester affects some early step in the response which is necessary for the triggering of cell replication; on-going dna replication is not significantly affected. phorbol 12,13-diacetate, a less potent analogue ... | 1978 | 146519 |
| microculture method for mixed lymphocyte cultures in the horse. | a miniaturized method for the mixed lymphocyte culture test in the horse is described. the test is performed in either round- or flat-bottom microtitration tissue culture plates. concentrations of responsing and stimulating cells are varied, depening on the experiment. significant discrimination between isogeneic and allogenic mixtures is possible after 120 hours' culture when cells are labeled ([3h]thymidine) for the last 16 to 18 hours of the test. | 1978 | 147041 |
| a dynein atpase inhibitor isolated from a commercial atp preparation. | preparations of atp from equine muscle contained an inhibitor of dynein mg2+-activated atpase. the inhibitory material was separated from the atp by molecular sieve filtration. the several molecular species of dynein extracted from three different axonemal sources were all inhibited; myosin atpase was not. with increasing amounts of inhibitor the inhibition did not go to completion but reached a plateau when the rate had been reduced to 1/5 the uninhibited rate. a plot of 1/[s] against 1/v at se ... | 1978 | 147108 |
