| failure of hypoxic pulmonary vasoconstriction in the canine asthma model. effect of prostaglandin inhibitors. | measurements of respiratory mechanics, arterial blood gases, and pulmonary vascular resistance were made before and 15 min after inhalation challenge with ascaris suum extract in dogs with natural sensitivity to this antigen. 25 of 47 dogs were treated before inhalation challenge with a prostaglandin inhibitor (90 mg/kg of aspirin or 2 mg/kg of indomethacin by intravenous infusion). in response to the challenge, bronchospasm developed in approximately half (responders) of each group reflected by ... | 1978 | 659609 |

| pathologic changes and pathogenesis of parascaris equorum infection in parasite-free pony foals. | parasite-free pony foals (n = 10) were infected orally with 1000,000 parascaris equorum embryonated eggs. one pony foal each was euthanatized on days 1, 3, 5, 7, 11, 16, 23, 27, 42, or 80 after infection. foals infected for more than 7 days showed signs of coughing, anorexia, rough coat, and weight loss. cellular changes in the blood were mild anemia, marked eosinophilia, and leukopenia. gross postmortem lesions included hemorrhage, edema, and white-to-yellow necrotic foci (0.5 to 1.00 mm) in lu ... | 1978 | 677534 |
| immunization of pigs against experimental ascaris suum infection by feeding ultraviolet-attenuated eggs. | pigs fed ascaris suum eggs attenuated by short-wave ultraviolet radiation developed a resistance to challenge infections that varied according to the protocols used. two doses of eggs irradiated at total exposures (et) of 150 muw-min/cm2 resulted in a reduction of adult worm burden in 3 groups challenged with 50, 100, or 500 eggs by 45, 35, and 49%, respectively. however, these results were not statistically significant (p greater than 0.05). three other groups were fed eggs as follows: group 1, ... | 1978 | 682067 |
| the prevalence of intestinal helminthiasis among the qashqai tribe in southern iran. | the prevalence and the intensity of intestinal helminthiasis in the qashqai tribe of southern iran were studied. infection with ascaris lumbricoides and trichuris trichura was low (6.1 and 0.8 per cent respectively) while the prevalence of trichostrongylus was 27.6 per cent of the total stool samples examined or 63.2 per cent of the total intestinal parasites found. this might be due to the mode of life of the tribe and the proximity of its people to domestic animals. | 1978 | 683695 |

| benzylpenicillin preparations can evoke a systemic anaphylactic reaction in guinea pigs. | all of the five commercially available benzylpenicillin preparations obtained from different sources and a pcg preparation prepared by filtration of a commercial pcg on sephadex g10 elicited the systemic anaphylactic reactions in guinea pigs which had been immunized with benzylpenicilloyl (bpo)-ascaris extract conjugate (bpo-as) mixed with aluminum bydroxide gel. these preparations could evoke no such reactions in guinea pigs immunized with bpo-bovine gamma globulin conjugate (bpo-bgg) emulsifie ... | 1978 | 701662 |
| new method for evaluating bronchomotor and bronchosecretory activities: effects of prostaglandins and antigen. | we devised a new method for measuring responses of canine airway musculature, bronchosecretion and bronchial vasculature simultaneously, in situ, and investigated the effects of prostaglandins f2alpha and e2 and antigen-antibody reaction by using this model. the right bronchial artery was perfused with blood at a constant flow under artificial respiration. airway musculature response was measured as a change in ventilation overflow with a modification of the konzett-rössler method; the airway se ... | 1978 | 702943 |

| gas exchange during acute experimental canine asthma. | the inert gas infusion technique was used to recover distributions of ventilation-perfusion ratios in anesthetized dogs during 17 episodes of acute asthma produced experimentally by broncho-provocation with aerosolized ascaris suum extract, methacholine, or histamine. regardless of the agent used, 2 general patterns of ventilation/perfusion maldistribution were observed. during mild attacks of bronchospasm, a broadening of the normal unimodal distribution of ventilation-perfusion ratios occurre ... | 1978 | 707880 |
| [experimental asthma in rats, and the effect of n (3', 4'-dimethoxycinnamoyl) anthranilic acid (n-5') (author's transl)]. | although guinea pigs have been frequently used as a model of asthma, antibodies produced in this species are generally gamma1 and gamma2 and belong to igg. the antibody responsible for asthmatic attacks in humans is ige, and such is quite different from gamma1 and gamma2, immunologically. guinea pigs are not therefore an adequate model for investigating anti-asthmatic drugs which inhibit ige-mediated mediator release, such as disodium cromoglycate. on the other hand, rats do produce an antibody ... | 1978 | 711029 |
| evidence for the metabolism of phospholipids and triacylglycerols in human ascaris lumbricoides. | human ascaris lumbricoides has the necessary mechanism for the biosynthesis and degradation of phospholipids and triacylglycerols, as in most other species. piperazine decreases the level of triacylglycerols of this parasite by stimulating the activity of lipase and partially inhibiting the activity of phosphatidate phosphatase. | 1978 | 720509 |
