| the pumping mechanism of the nematode esophagus. | the radial orientation of the myofilaments in the nematode esophagus raises interesting questions as to how such a structure can function as a pump. a physical model of the esophagus of ascaris lumbricoides was developed and the membrane theory of shells applied in order to relate the observed dimensional changes to myofilament force, pressure stresses, and membrane elastic constants. by stressing the excised esophagus passively with osmotic pressure, the esophagus was shown to be elastically an ... | 1978 | 667292 |

| eosinophilia and mast cell hyperplasia induced by parasite phospholipid. | phospholipid preparations from the nematode ascaris suum or cysts of echinococcus granulosus (hydatid cysts) induced an eosinophilia when injected into the peritoneal cavity of rats. peritoneal eosinophilia persisted throughout 21 days of daily injections of ascaris lipid and was accompanied by blood eosinophilia, mast cell granule lysis and mast cell hyperplasia. the active material consisted of lecithin and lecithin plasmalogen, and in aqueous suspension had a membrane-like appearance. electro ... | 1977 | 876690 |
| ascariasis: the development of eggs of ascaris suum under the conditions prevailing in a pig house. | eggs were collected from gravid female ascaris suum in the abattoir. cultures were prepared with the eggs in 2 to 3 mm depth of 1 per cent sulphuric acid or on the surface of 2% aqueous agar. they were allowed to develop in a piggery, fresh cultures being started at intervals from january to september. eggs on the surface of agar developed failry uniformly and a high proportion eventually reached l2. in contrast those under 1% sulphuric acid were less uniform, slower in development and generally ... | 1977 | 878244 |
| effect of unilateral vagus blockade on allergen-induced airway obstruction: results of short- and long-term experiments. | unilateral application of ascaris extract on segment bronchus as the influence of contralateral vagus blockade on reflex bronchoconstriction was studied on four boxer dogs in a first group (a) of experiments: ascaris extract was applied in liquid form directly through a catheter into the right segment bronchus. this application was repeated after contralateral vagus blockade and once more after its lavage. all the animals showed an increase of airway resistance under local application of ascaris ... | 1977 | 882724 |

| changes in airway mast cells and histamine caused by antigen aerosol in allergic dogs. | we studied the effect of inhaled specific antigen on airflow resistance, histamine concentration, and mast cell numbers in airway tissues in allergic dogs. in each of six allergic dogs with open chests, inhalation of specific antigen aerosol (ascaris suum) increased airflow resistance from 0.30+/-0.40 (mean+/-se) to 2.8+/-0.41 cmh2o/1 per s (p less than 0.05); decreased mast cell number from 38.6+/-3.2 to 24.3+/-4.5 mast cells/mm2 (p less than 0.05); decreased histamine (per mg airway tissue) fr ... | 1977 | 893281 |
| [studies of the corticosteroid hormones in the nematode, ascaris suum]. | four steroids from tissues of ascaris suum were isolated and identified by means of the thin-layer chromatography and fluorimetric methods as corticosterone, cortisol, alodosterone and dehydrocorticosterone. corticosterone, cortisol and alodosterone are corticosteroid hormones while dehydrocorticosterone is a product of a metabolic transformation of corticosterone. it seems likely that the presence of corticosteroid hormones in tissues of a. suum is indicative of their participation in the metab ... | 1977 | 896275 |

| the pattern of parasitic infection in human gut at the specialist hospital, benin city, nigeria. | in a survey of 6213 persons conducted between january 1973 to december 1974, at the specialist hospital, benin city, the most common helminths were necator americanus (16.8%), ascaris lumbricoides (19l5%) and trichuris trichiur (5-9%). dicrocoelium hospes (0-06%) was also recorded and this may become an important liver parasite of man in nigeria. its snail vectors are believed to be species of limicolaria and achatina which are widely dispersed in nigeria. entamoeba coli and e. histolytica showe ... | 1977 | 849017 |
| evaluation of the effect of different methods of control of soil-transmitted helminths in khuzestan, southwest iran. | three methods of control of soil-transmitted helminths, namely, sanitation, mass-treatment, and sanitation plus mass-treatment, were tried in 15 villages in khuzestan, southwest iran. stool samples from the inhabitants of each village were examined both quantitatively and qualitatively just before starting each control method and again about 4 years later, except for the inhabitants of one village whose stools were re-examined 7 months after moving to a new settlement. sanitation measures consis ... | 1977 | 848644 |
| epidemiology and mass-treatment of ascariasis in six rural communities in central iran. | in six villages near isfahan in central iran 1,455 persons were examined for intestinal parasites. those with ascaris infection were treated with pyrantel pamoate in a single dose of 10 mg/kg body weight and all stools passed during 48 hours after treatment were collected in plastic pans and screened for worms which were then sexed and measured. ascaris infection rates, 87--95% in the six villages before treatment, were reduced to 1--8% (average 5%) and the mean number of eggs in the feces was r ... | 1977 | 907049 |
| intraocular ige antibody induced in guinea pigs with ascaris suum larvae. | the systemic and local (intraocular) ige antibody responses to infective and heat-killed ascaris suum larvae were examined in guinea pigs. ige antibody, demonstrated by the 6-day p-k test, was found in anterior chamber fluid following primary intravitreal injection of live second-stage a. suum larvae and in some instances occurred when no serum p-k activity was demonstrable. no intraocular ige antibody was induced by primary intravitreal injection of heat-killed larvae. a brisk intraocular and s ... | 1977 | 908652 |

| biliary ascariasis presenting in the united states. | infestation of the bile ducts by the adult ascaris lumbricoides roundworm is a common condition in many parts of the world. the most frequent clinical presentation is as upper abdominal colicky pain with a normal or only slightly raised serum bilirubin. in most cases these worms can be visualized by intravenous cholangiography because of the absence of obstructive jaundice and can therefore be specifically treated by nonsurgical methods. the radiographic appearance is diagnostic. this is the fir ... | 1977 | 920717 |

| acute pancreatitis in pregnancy with ascaris infestation. | two cases of acute pancreatitis in pregnancy occurred among vietnamese evacuees in arkansas. in both cases, ascaris lumbricoides seemed the likely cause. in endemic areas including the rural southeastern united states, a high index of suspicion for ascariasis is needed because these worms may cause a variety of abdominal disorders including pancreatitis, cholecystitis, and bowel obstruction. in appropriate settings, a therapeutic trial with antihelminthics is indicated. | 1977 | 831188 |
| the interaction between anthelmintic drugs and histamine in ascaris suum. | 1 piperazine reduced the histamine content of ascaris suum, yet it greatly increased the uptake of histamine from the surrounding medium, the neuromuscular structures of the nematode preferentially increasing in amount. 2 bephenium reduced the histamine content of ascaris and the uptake of histamine from the surrounding medium. however, the relative amount in the neuromuscular structures increased. 3 the flaccid paralysing action of piperazine may thus involve increased histamine absorption wher ... | 1976 | 823998 |
