| naturally occurring inhibitors of intracellular proteinases. | the papain inhibitor isolated from chicken egg white inhibits the enzymatic activity of cathepsin b1 and cathepsin c. the inhibitor bears two nonoverlapping reactive sites: one binds cathepsin b1, papain, ficin, and bromelain, the other one cathepsin c. the inhibitor decreases the degree of an immunologic hypersensitive reaction, the so-called arthus reaction. a statistically significant inhibition of this immunologically developed inflammation occurs only if the inhibitor is applied intradermal ... | 1977 | 616734 |
| isolation of messenger rna coding for eggshell protein of the dna-eliminating nematode ascaris lumbricoides. | poly(a)-containing rna from polyploid uterine epithelial cells of ascaris lumbricoides has been isolated by poly(u)-sepharose chromatography. the bulk of poly(a)-containing rna migrates as 18-s rna in formamide/polyacrylamide gels. in a cell-free wheat germ system, this rna directs the synthesis of a polypeptide with identical migration behavior in dodecylsulphate/urea/polyacrylamide gels as the polypeptide isolated from the proteinaceous eggshell. the two proteins reveal almost identical peptid ... | 1978 | 624288 |
| in vivo effects of mebendazole and levamisole in the treatment of trichuriasis and ascariasis. | the anthelmintic drugs mebendazole (vermox) and levamisole were tested in patients for their possible ovicidal effects on the eggs of trichuris trichiura and ascaris lumbricoides. the patients studied were 20 africans of sierra leone, and 11 children of nassau, bahamas. egg counts were made before treatment, and for 5 consecutive days following treatment. eggs were incubated in 2.5% aqueous potassium dichromate and percentages of larval development were determined. mebendazole completely inhibit ... | 1978 | 626274 |

| 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 |
| 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 |
| 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 |
