| experimental canine anaphylaxis: cyclic nucleotides, histamine, and lung function. | we studied the effects of ascaris suum antigen (iv) in 32 natively allergic, anesthetized dogs. after thoracotomy, bilateral cervical vagotomy, and propranolol, samples of peripheral lung frozen in situ were obtained for measurement of cyclic nucleotides and histamine. following ascaris, lung histamine decreased 20.4 +/- 3.7% (mean +/- se), camp increased 391 +/- 122%, and cgmp increased 110 +/- 20% with increased plasma histamine and physiological changes of anaphylaxis. no significant changes ... | 1979 | 224010 |

| [endoparasites of calves in large herds]. | the authors present preliminary results of the coprological examination of calves in large-capacity calf-houses. in a new large-capacity calf-house in the benesov district in the central-bohemian region, 200 samples of faeces were examined according to breza (1957) and further examinations were performed regularly in a group of 42 calves from the age of 0.5 to 6 months. the tests revealed 13 species of endoparasites, including eight species of coccidia: eimeria auburnensis, e. alabamensis. e. bo ... | 1977 | 413242 |
| inhibition of allergic reactions by cromoglycate and by a new antiallergy drug u-42,585e. ii. activity in primates against aerosolized ascaris suum antigen. | immediate type hypersensitivity to ascaris antigen in rhesus reactor monkeys was used to assess the pharmacologic profile of cromolyn na (dscg) and a new inhibitor of ige-mediated lung function changes (u-42,585e). two parameters used to measure lung function, respiratory rate increase and tidal volume decrease, were significantly altered in a dose-related fashion by u-42,585e when the latter was administered either by the intravenous, intrabronchial, or the oral route. oral activity of u-42,585 ... | 1978 | 415987 |
| a comparative trial of the anthelminthic efficacy of pyrantel pamoate (combantrin) and thiabendazole (mintezol). | the anthelminthic efficacy of pyrantel pamoate (combantrin) in a single dose of 10 mg/kg body weight was compared with that of thiabendazole (mintezol) in two doses each of 25 mg/kg body weight in a controlled trial. follow-up examination, 6 weeks after treatment with combantrin gave cure rates of 93.8%, and 29.1% for infection with ascaris and the hookworm respectively, and 44.3% and 27.3% in those treated with mintezol. the reduction in hookworm egg counts was higher in patients treated with c ... | 1977 | 416671 |

| ascaris lumbricoides and perforation of the ileum: a critical review. | ileal perforation due to typhoid bacilli is the commonest cause of peritonitis in the tropics. perforation due to ascaris lumbricoides is rare. three cases of ileal perforation believed to be due to a. lumbricoides are presented and the evidence critically reviewed. it is suggested that signs of heavy infestation with a. lumbricoides make a diagnosis of intestinal perforation more likely in a patient with an acute abdomen. | 1979 | 420985 |
| biochemical studies on the muscle microsomes of ascaris lumbricoides var. suum. i. biochemical characterization and electron transport of ascaris microsomes. | two subcellular fraction, p-1 and p-2, were isolated by differential centrifugation from 0.25 m sucrose muscle homogenates of the parasitic roundworm, ascaris lumbricoides suum. morphological studies indicated that p-1 fraction consisted of intact mitochondria, whereas p-2 fraction consisted almost exclusively of vesicular components. the difference spectrum of ascaris microsomes showed a characteristic b-type cytochrome spectrum with three distinct absorption peaks at 560, 525, and 424 nm. howe ... | 1979 | 422535 |
| induction, isolation and surface marker studies on bovine eosinophils. | a crude extract from ascaris suum was infused into the teat canal of heifers to serve as an irritant or an antigens. the cells present in the mammary gland following such stimulation were assessed over a period of 2 weeks. prior to stimulation there were few cells, predominantly macrophages, however, by 12 h post-stimulation a larger number of eosinophils and neutrophils were present. the eosinophils, which represented approximately 50% of the total population, could be purified by ficoll-hypaqu ... | 1979 | 422852 |

| comparative studies on actins from various sources. fragments of actins from ascaris muscle cleaved at cysteinyl residues in comparison with those of other actins. | pure actins were obtained from various animal muscles: vertebrata (skeletal, smooth, and cardiac muscles), prochordata (smooth muscle), nematoda (obliquely striated muscle), and mollusca (striated, smooth and obliquely striated muscles). these actins were all identical in apparent molecular weight on sodium dodecyl sulfate-polyacrylamide gel electrophoresis. all actins treated with 2-nitro-5-thiocyanobenzoic acid yielded four major (about 33,000, 26,000, 24,000, and less than 10,000 daltons) and ... | 1979 | 429256 |

| immunopathology of toxocara canis and ascaris suum infections of the eye: the role of the eosinophil. | intravitreal infection of guinea pigs with second-stage larvae of toxocara canis and second- and fourth-stage larvae of ascaris suum induced intraocular ige antibodies and a dense eosinophil infiltration in the anterior chamber and throughout the uveal tract. the eosinophil infiltrate began within 1 day after infection and persisted for as long as 51 days. by day 12 after intravitreal infection, the injected ascarid larvae were surrounded by granulomas which consisted almost entirely of eosinoph ... | 1979 | 511459 |
| therapeutical influence of vagus blockade on antigen-induced airway obstruction. | the influence of bilateral vagus blockade on airway resistance induced by allergen exposure, while aerosol was given, was tested on 3 dogs. the therapeutic effect of vagus blockade could be demonstrated, which showed to be in a same degree as its prophylactic effect demonstrated in experiences before. | 1979 | 441527 |
| the role of upper airways in antigen-induced bronchoconstriction. | the bronchoconstrictor effect of antigen was tested in 15 dogs. the upper and the lower airways were sequently exposed through a specially confected endotracheal tube. the antigen was also generally administered through a mouth mask. bronchoconstriction was induced after each kind of exposure. the results argue for reflex bronchoconstriction. the sensory receptors localized in the upper part of the airways are responsible for about 50% of antigen-induced bronchoconstriction. the decrease of po2a ... | 1979 | 441542 |

| relationship between serum ige levels and intestinal parasite load in african populations. | serum ige determinations and coproparasitological analyses were carried out on 161 individuals from two distinct ethnic groups (hutus and twas) from two regions in rwanda (north and south). the cumulative parasitosis index (calculated for each individual as the sum of the scores for the four most frequent intestinal parasites) show a linear relation with ige levels up to a plateau, with no clear pattern of correlation between the score for any given parasite and the ige level. such a direct quan ... | 1979 | 447419 |
| regulation of ige antibody production by serum molecules. iv. complete freund's adjuvant induces both enhancing and suppressive activities detectable in the serum of low and high responder mice. | two biologically active serum molecules manifesting precisely opposite biologic effects, both of which are selective for ige antibody synthesis, can be detected in the serum and ascites fluids of cfa-immune mice. one activity, described previously, is suppressive and hence termed suppressive factor of allergy (sfa); the other, reported for the first time herein, is enhancing and has been termed enhancing factor of allergy (efa). the ability to detect one vs the other activity requires certain sp ... | 1979 | 448123 |
