IL-12 is a heterodimeric cytokine that has been shown to enhance natural killer (NK) and cytotoxic T lymphocyte (CTL) responses, and to induce IFN-gamma production in vitro. In this study, we have examined the effects in vivo of administering purified murine rIL-12 to normal mice. Daily injections of rIL-12 i.p. (1 ng to 10 micrograms/day) caused(More)
Introduction. This paper discusses the role uncertainty plays in judgments of the meaning and significance of ideas and texts encountered by scholars in the context of their ongoing research activities. Method. Two experienced scholars were observed as part of a two-year ethnographic study of their ongoing research practices. Layered transcriptions of(More)
Trophoblasts in normal and Brucella abortus-infected caprine placentas were examined by ultrastructural morphometric analysis to establish structural relationships of B abortus with cytoplasmic organelles; brucellae were identified with colloidal gold-labeled anti-B abortus bovine IgG. Cytotrophoblasts had large numbers of B abortus in cisternae of rough(More)
Introduction. This paper discusses how exploring the research process indepth and over time contributes to a fuller understanding of interactions with various representations of information. Method. A longitudinal ethnographic study explored decisions made by two informants involved in scholarly research. Relevance assessment and information seeking were(More)
IL-12 is a cytokine that promotes cell-mediated immunity by promoting Th1-type cytokine responses, enhancing the lytic activity of NK/LAK cells, augmenting specific CTL responses, and inducing the production of IFN-gamma. On the other hand, IL-12 suppresses the development of Th2-type cytokine responses and humoral immunity, particularly IgGl and IgE(More)
Interleukin (IL)-12 synergizes with other cytokines to stimulate the proliferation and differentiation of early hematopoietic progenitors in vitro. However, in vivo administration of IL-12 decreases peripheral blood counts and bone marrow hematopoiesis. Here, we used interferon (IFN) gamma receptor-deficient (IFN gamma R-/-) mice to investigate whether the(More)
Interleukin 12 (IL-12) activates natural killer (NK) and T cells with the secondary synthesis and release of interferon-gamma (IFN-gamma) and other cytokines. IL-12-induced organ alterations are reported for mice and the pathogenetic role of IFN-gamma is investigated by the use of mice deficient in the IFN-gamma receptor (IFN-gamma R-/-). IL-12 caused a(More)
Interleukin (IL)-1 is an early mediator of host response to inflammation, although its contribution to individual components of the acute phase reaction is still unclear. To evaluate how the hemodynamic, metabolic, and hormonal responses to sublethal endotoxemia compare with IL-1 administration, baboons received intravenously either lipopolysaccharide (LPS)(More)
BACKGROUND The reverse transcriptase inhibitor, 2',3'-dideoxycytidine (ddC), causes a dose-limiting peripheral neuropathy in humans, the mechanism of which is unknown. Rabbits given ddC develop peripheral myelinopathy and axonopathy, but it has not been determined if either the myelin or axonal changes are primary or if they occur concurrently. (More)
