| structure and function of the glandular vas deferens in ascaris suum (nematoda). | the glandular vas deferens in the linearly arranged male reproductive tract in ascaris suum produces substances which cause marked morphological and physiological changes in the spermatozoa. the glandular secretions, presumably formed by the rough endoplasmic reticulum and golgi saccules, are extruded from the cells and coalesce to form homogeneous masses in the gland lumen. in sexually inactive worms the secretory material is separated from the spermatozoa by a sphincter comprised of neuro-musc ... | 1976 | 1033989 |
| [the average degree of parasitosis, a criterion for evaluation of the geohelminthic contamination of a population, and for application of santiary measures]. | the severity of ascaridiasis in a region depends first of all on the degree of pollution by ascaris ova of the environemtn and consquently on the per diem output of ascaris ova in the stools. therefore, the importance of ascaridiasis as an endemic disease, depends of course upon the number of positive cases, their prevalence, but still more, it depends upon the intensity of the infection of the diseased population (global parasitic discharge). practically, this concept of global parasitic discha ... | 1976 | 1036479 |
| chronic diarrhoeal diseases in adults (a preliminary report). | the relationship of chronic diarrhoeal diseases in adults on socio-economic condition, parasitic infestation and degree of anaemia have been investigated. the disease was more prevalent in poor socio-economic group of people. most of the patients had mixed parasitic infestations. anaemia was present in all the cases. difference in the degree of anaemia was not significant amongst the patients having either ascaris or hookworm infestation. | 1976 | 1037200 |
| biology of soil-transmitted helminths: the massive infection. | soil-transmitted helminth infections when light-to-moderate usually are well tolerated, but heavy-to massive infections invariably cause disease. a massive infection with ascaris lumbricoides may cause intestinal obstruction, liver abscess, or some other condition requiring surgical treatment; more regularly, however, ascaris disease is a form of malnutrition. trichuris trichiura causes diarrhea and dysentery and, at times, rectal prolapse. the hookworms, necator americanus and ancylostoma duode ... | 1975 | 1052507 |

| a study of human intestinal helminthiases on kar kar island, madang province. | this paper reports the results of an epidemiological survey of intestinal helminths in a village on kar kar island, madang province. samples of blood and faeces were collected from 320 people from all age-groups living in 51 houses in kaul village. three helminth species were recorded: ascaris lumbricoides infections were highest and heaviest in childhood, and fell to low levels in adult life, the overall infection rate being 57%. more than 70% of the adult population were infected with necator ... | 1976 | 1072172 |
| rabbit lymphocyte populations responding to haptenic and carrier determinants for dna synthesis. | mesenteric lymph node cells from rabbits primed with dinitrophenyl derivative of either ascaris extract (dnp-asc) or ragweed fraction d (dnp-rag) were stimulated by the priming antigen, free homologous carrier, or with the hapten conjugated with rabbit serum albumin (dnp-rsa), and increase in dna synthesis was observed by 3h-thymidine incorporation. the results showed that both free carrier and dnp-rsa stimulated dna synthesis. the response of the primed lymph node cells to dnp-homologous conjug ... | 1975 | 1078682 |
| regulation of antibody response in vitro. ix. induction of secondary anti-hapten igg antibody response by anti-immunoglobulin and enhancing soluble factor. | attempts were made to induce antibody response of hapten-primed cells by stimulation with anti-immunoglobulin (ig) antibody and cellfree supernatant (cfs) which contained nonspecific enhancing factor. mesenteric lymph node cells were obtained from rabbits which were primed with dinitrophenylated ragweed antigen (dnp-rag), and the primed cells were incubated in vitro with either anti-rabbit gamma-chain or anti-fab antibody for 24 hr. after washing, the cells were cultured in cfs which was obtaine ... | 1975 | 1079034 |
| cell interactions between histoincompatible t and b lymphocytes. viii. in vivo cooperative responses between lymphocytes are controlled by genes in the k-end of the h-2 complex. | the genetic restrictions for successful carrier-primed t cell and hapten-primed b cell cooperative interactions were established in a totally in vivo double adoptive transfer system. in complementation experiments, we have demonstrated that genes localized in the k-end of the h-2 complex control successful t-b cell cooperative interactions. thus, dba/2 klh-primed t cells cooperated with (c3h times c3h.oh)f1 and (c3h times c3h.ol)f1 dnp-primed b cells to make a secondary response to dnp-klh, but ... | 1975 | 1079217 |
| the two human trypsinogens. inhibition spectra of the two human trypsins derived from their purified zymogens. | the two human anionic trypsinogens 1 and 2 were purified from human pancreatic juice by gel filtration on sephadex g-100 and by chromatography on deae-cellulose. after activation of their respective zymogens by porcine enterokinase, human trypsins 1 and 2 were studied for their reaction with a wide variety of proteinase inhibitors. kunitz pancreatic trypsin inhibitor and human pancreatic secretory trypsin inhibitor completely inhibited both human trypsins at a stoichiometric inhibitor-to-enzyme ... | 1975 | 1079768 |
| triggering mechanism of b lymphocytes. i. effect of anti-immunoglobulin and enhancing soluble factor on differentiation and proliferation of b cells. | stimulation of rabbit mesenteric lymphocytes with anti-immunoglobulin antibody (anti-ig) for 24 hr (first stage of culture) followed by the addition of enhancing soluble factor (second stage of culture) induced the formation of igg. the presence of mitotic inhibitors, such as cytosine arabinoside (ara-c), hydroxyurea (hu), with anti-ig for the first 24 hr of incubation did not inhibit the production of igg induced by anti-ig and soluble factor. the addition of cytochalasin-b in the first stage o ... | 1975 | 1080773 |
| the effect of the thymus-independent antigens, collagen and synthetic collagen-like polypeptide, on the requirement of cell cooperation in the immune response to thymus-dependent antigens. | the effect of thymus-independent antigens on the need for cell cooperation in the immune response to thymus-dependent antigens was investigated. irradiated recipient mice transplanted with either bone marrow cells or a mixture of bone marrow and thymus cells, were immunized with the thymus-independent antigen (pro-gly-pro)n covalently conjugated to the thymus-dependent ovalbumin, or with a mixture of (pro-gly-pro)n and ovalbumin. in both cases an effective response towards ovalbumin was observed ... | 1975 | 1086249 |

| studies on immune responses to parasite antigens in mice. i. ascaris suum larvae numbers and antiphosphorylcholine responses in infected mice of various strains and in hypothymic nu/nu mice. | in terms of day 7 lung larvae numbers, mice vary markedly in their suscepibility to a first infection with the nematode worms, ascaris suum, and the highly susceptible strain, c57bl, is resistant to second infection. time course studies suggested that the period of residence in the liver or migration to, or into, the lungs are stages of the life cycle in which natural or acquired resistance of the host is expressed. the traits, susceptibility and resistance to first infection, were under polygen ... | 1976 | 1087923 |
| studies on immune responses to parasite antigens in mice. ii. aspects of the t cell dependence of circulating reagin production to ascaris suum antigens. | heat-labile, rat skin-fixing antibodies were detected readily in the sera of young female mice dosed intranasally with the body fluid of ascaris suum (abf) and the adjuvant, bordetella pertussis vaccine (bpv). in addition, washed cell suspensions prepared from spleen and the lymph nodes regional to the lungs were positive in an adoptive cutaneous anaphylaxis assay, an assay which may detect activities of reagins associated with mast cells rather than reaginic antibody-secreting cells. the intrap ... | 1976 | 1087924 |
