| a phosphorylcholine idiotype related to tepc 15 in mice infected with ascaris suum. | a serum component, binding antigens having phosphorylcholine (pc) determinants were induced in several strains of mice by infection with ascaris suum. this component was isolated and demonstrated to be an igm (k) anti-pc antibody having idiotypic determinants in common with the iga pc-binding myeloma protein tepc 15. rabbit anti-idiotypic antisera prepared with this component had idiotypic specificity for tepc 15 and cross-idiotypic recognition of mopc 167 and mcpc 603, all iga pc-binding myelom ... | 1976 | 1254963 |
| the resolution of ascaris cuticle collagen into three chain types. | reduced and methylated collagen from ascaris lumbricoides cuticle was resolved into three major components by chromatography on phosphocellulose. the components have similar molecular weights of about 52,000 by sedimentation equilbrium and molecular sieve chromatography, but they have different amino acid compositions. since they do not appear to be stoichiometrically related, they apparently represent chains from collagens of more than one type. all three chains contain about 27 residue % glyci ... | 1976 | 1259947 |
| the mediation of tissue eosinophilia in hypersensitivity reaction. i. isolation of two different chemotactic factors from dnp-ascaris extract-induced skin lesion in guinea-pig. | in an active cutaneous anaphylaxis induced by dnp-ascaris extract in guinea-pig, tissue eosinophilia manifested two phases; the early and mild phase became maximal in about 6 h, while the delayed and intense phase in 18-24 h. skin extracts from the lesions exhibited chemotactic activities for eosinophils, respectively comparable to the intensity of tissue eosinophilia in each phase; and two different chemotactic factors for eosinophils of skin extracts were separated by gel filtration on sephade ... | 1976 | 1262051 |

| demonstration and possible function of nadh:nad+ transhydrogenase from ascaris muscle mitochondria. | mitochondria from the muscle of ascaris lumbricoides var. suis function anaerobically. nadh is generated in the intermembrane space as a consequence of the "malic" enzyme reaction. it has been suggested that this reducing equivalent in the form of hydride ion, would be translocated across the inner membrane in order to mediate atp generation via the fumarate reductase reaction. in accord with this suggestion, intact ascaris mitochondria showed appreciable nadh oxidase activity. sonication result ... | 1976 | 1262321 |
| characterization of proteins from ascaris lumbricoides which bind specifically to carboxypeptidase. | inhibitors of the peptidase and esterase activities of carboxypeptidases a and b have been isolated from extracts of ascaris lumbricoides var suis. these proteins were obtained by treatment of the aqueous extracts at low ph, precipitation with ammonium sulfate, molecular sieving on bio-gel p-4, and chromatography on deae-cellulose. the inhibitors were resolved into three homogeneous peaks on cm-cellulose. these components, cm-a, cm-b, and cm-c, have constant specific activity and were recovered ... | 1976 | 1262322 |
| scanning electron microscopy of the lip denticiles of ascaris suum adults of known ages. | purebred hampshire pigs, farrowed and maintained under conditions precluding extraneous helminth infection, were exposed to a single dose of 10,000 ascaris suum infective eggs. the pigs were killed at intervals of 28, 41, 55, 86, 115, 145, 175, and 206 days after infection. at necropsy, no gross lesions were found in the lungs or livers of infected pigs. the worms were recovered from the small intestine, identified, counted, and fixed. the heads were excised, critical point dried, mounted en fac ... | 1976 | 1263037 |

| alteration of the response of guinea pigs to freund's complete adjuvant by ascaris extract: a preliminary histologic study. | freund's adjuvant has been asserted to cause systemic complications in man similar to those occurring with b.c.g. vaccine. in search of factors predisposing to such complications of this vaccine, the potential role of a coexisting parasitic infestation was considered. a potentiating effect of the ascaris antigen on the pathological changes produced in guinea pigs by intraperitoneally injected freund's complete adjuvant was noted. the pertinency of this observation to immunotherapy of cancer with ... | 1976 | 1275325 |

| substance p as a potent stimulator of sneeze responses in experimental allergic rhinitis of guinea pigs. | substance p was examined for sneeze-inducing activity and its involvement of sneeze responses in experimental allergic rhinitis. substance p, dripped into a nostril of guinea pigs, at concentrations of 100 pm and above induced sneezing in a dose-dependent fashion. the activity of substance p was not affected by the previous subcutaneous injections of capsaicin that depleted substance p in nerve fibers. histamine induced sneezing at concentrations of 30 mm and above and the activity was reduced b ... | 1992 | 1284191 |

| [the signal transduction of serotonin secretion involves protein tyrosine phosphorylation in rat basophilic leukemia cells]. | we investigated the signal transduction of serotonin secretion by stimulation with dnp-ascaris antigen or ionomycin in rat basophilic leukemia cells (rbl-2h3). the modes of action of antigen and ionomycin for serotonin secretion were shown to be similar. the treatment of cells with antigen resulted in increased tyrosine phosphorylation of 105 and 72 kda proteins, in particular, the tyrosine phosphorylation of 72 kda protein seemed to correlate with serotonin secretion. furthermore, we observed t ... | 1992 | 1290415 |
| isoenzymatic pattern and structure of glutamate dehydrogenase from ascaris suum. | the isoenzymatic pattern of glutamate dehydrogenase (gdh) has been described for ascaris suum a parasite of sus scrofa domestica. only one band of activity has been revealed, suggesting a monomorphic condition for this enzyme. also, the structure of gdh has been assayed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (sds-page) and silver staining. only one subunit was present with a molecular weight of about 55,000. a hexameric structure for gdh of a. suum is suggested. | 1992 | 1293199 |
