| [contribution to the morphology and pathogenesis of eosinophilic colitis (author's transl)]. | a 40 year old woman suffered from acute diarrhea and convulsive abdominal pains. because of a palpable tumor of the right lower abdomen, which was thought to be localized in the deeper layers of the colon ascendens, a hemicolectomy on the right side was performed. histologically there was a severe phlegmonous eosinophilic inflammation of the bowel wall and the surrounding fatty tissue. a parasite was found within the strongly oedematous submucosal layer. the different forms of eosinophilic infla ... | 1981 | 7303781 |

| recidivous acute urticaria caused by anisakis simplex. | this study aimed to determine the cause of acute recidivous urticaria in patients who usually eat fish or other seafood. twenty-five patients were studied. the skin prick test with larval anisakis simplex extract was performed; total and specific ige against a. simplex was measured with the cap system; specific antibodies to a. simplex were determined by elisa; and immunorecognition patterns of the sera were studied by western blot. nineteen patients showed specific ige to a. simplex, but specif ... | 1997 | 9360749 |
| specific antibody patterns of wistar rats inoculated with third stage larvae of anisakis simplex. | levels of excretory-secretory (es)-specific antibody were measured in wistar rats inoculated with 1, 5, or 20 third stage larvae (l3) of anisakis simplex. primary inoculation induced es-specific igm and igg titers, paralleling inoculum size. secondary inoculations resulted in an igm and igg titer augmentation in 1 or 5 larvae-inoculated animals to levels comparable to those of animals inoculated with 20 larvae, but titers in high inoculum animals did not increase upon secondary inoculation. prim ... | 1995 | 7623194 |
| hyaluronidases of the gastrointestinal invasive nematodes ancylostoma caninum and anisakis simplex: possible functions in the pathogenesis of human zoonoses. | the gastrointestinal invasive stages of two parasitic nematodes, ancylostoma caninum and anisakis simplex, were each found to release in vitro a hydrolytic enzyme that degrades the glycosaminoglycan hyaluronic acid. the parasite hyaluronidases were partially purified by ion-exchange chromatography and biochemically characterized. the hyaluronidase from a. caninum adult worms had a molecular weight of 65,000 and a ph optimum of 6 with activity at neutral ph, while the hyaluronidase from a. simple ... | 1994 | 7930737 |
| characterization of the serine protease and serine protease inhibitor from the tissue-penetrating nematode anisakis simplex. | a serine protease and a serine protease inhibitor were purified from infective larvae of the parasitic nematode anisakis simplex. the serine protease was found to be trypsin-like and preferentially cleaved substrates with the basic amino acid arginine at the p1 position (z-gly-pro-arg-amc (where z is benzyloxycarbonyl), km = 0.019 mm, and z-phe-pro-arg-amc, km = 0.013 mm) at rates similar to those determined for trypsin (0.002 mm and 0.006 mm, respectively). however, the presence of a bulky hydr ... | 1994 | 7961683 |

| [allergy to anisakis simplex. report of 2 cases and review of the literature]. | anisakis simplex is a nematode which parasitizes mainly fish and cephalopods and accidentally human beings after ingestion. apart from the different digestive syndromes, this organism has recently been involved as cause of ige-mediated allergic reactions of variable degree (urticaria to severe angioedema). in this report three patients with the diagnosis of allergy to anisakis simplex are reported and a review of the literature is made. | 1998 | 9803780 |

| the infection status of anisakid larvae in marine fish and cephalopods from the bohai sea, china and their taxonomical consideration. | the infection status of anisakid larvae was examined in 290 marine fish of 25 species and in 108 cephalopods of 3 species purchased in bayuquan region, yingko city nearby the coast of the bohai sea from may to august 1992. a total of 7,327 larvae were collected from 156 fish of 19 species and 8 squids of one species. the 3rd-stage larvae of anisakis simplex were collected from 121 fish (63.4%) of 15 species (n = 191) and from 8 squids (14.8%) of one species (n = 54), and they were total, 5,992 ( ... | 1997 | 9100435 |
| isotype-specific immune responses in murine experimental anisakiasis. | a murine experimental model of anisakiasis has been developed in balb/c and c57bl/10 mice orally inoculated with an anisakis simplex living third stage larva (l3) in order to investigate isotype-specific immune responses against excretory-secretory (es) products and crude extracts (ce) from l3. specific antibody production showed similar patterns against both es and ce antigens with higher levels against the latter. the dynamics of the production showed the earliest responses in balb/c, in which ... | 1998 | 9916551 |
| the use of ige immunoblotting as a diagnostic tool in anisakis simplex allergy. | the fish parasite anisakis simplex is the etiologic agent of anisakiasis and induces ige-mediated reactions. skin prick tests (spts) and the measurement of specific ige to a. simplex were, in our experience, not valid tools with which to discriminate between allergic and nonallergic patients because many control subjects also had positive results. | 1997 | 9111494 |
| sensitization to anisakis simplex: an unusual presentation. | it has recently been published patients suffering from urticaria or anaphylaxia induced by nematodes usually parasitizing fishs or cephalopode, in whom, anisakis simplex (ak) sensitization prevalence was detected up to 37%. we tried out a prospective study to evaluate the presence of ak specific-ige in an asthmatic population, comparing to other group of patients with urticaria. complaints related to food ingestion were recorded in both, and dietetic measures were advised. thirteen patients (13/ ... | 1997 | 9150840 |
| genetic and ecological data on the anisakis simplex complex, with evidence for a new species (nematoda, ascaridoidea, anisakidae). | isozyme analysis at 24 loci was carried out on anisakid nematodes of the anisakis simplex complex, recovered from various intermediate/paratenic (squid, fish) and definitive (marine mammals) hosts from various parts of the world. a number of samples were found to belong to a. simplex sensu stricto and anisakis pegreffii, widely extending the geographic ranges and the number of hosts of these 2 species. in addition, a new distinct gene pool was detected, showing different alleles with respect to ... | 1997 | 9194819 |
| effects of anisakis simplex on nitric oxide production in j774 macrophages. | since nitric oxide (no) was recognized as a potent microbicidal agent, its role in host defence against intracellular parasites has been widely demonstrated. recent evidence suggests a role for no in combating extracellular and multicellular pathogens. this defence activity has been demonstrated toward the larvae of schistosoma mansoni, microfilariae of onchocerca linealis, several stages of brugia malayi and protoscoleces of echinococcus multilocularis. many parasites suppress th1 lymphocytes a ... | 1998 | 10225390 |
| in vitro study on the effect of larval excretory/secretory products and crude extracts from anisakis simplex on blood coagulation. | the anticoagulant action of anisakis simplex larvae on human blood in vitro was examined. anticoagulant activity was assessed by routine screening tests that evaluate the overall competency of the coagulant mechanism. a slight prolongation of the prothrombin time (pt) was observed with the larval crude extracts. prolongation of the pt was seen at a concentration of excretory/secretory (es) products greater than 62.5 micrograms/ml. no prolongation of the activated partial thromboplastin time (ptt ... | 1996 | 9198584 |
