OBJECTIVE The aim of this study was to investigate associations between four categories of maltreatment and substance use among adolescents. METHOD All 10th through 12th graders n = 2,187) at six public high schools in a rural Oregon county filled out an anonymous survey that included questions about their experience of emotional, sexual, and physical(More)
Anti-group A streptococcal monoclonal antibodies were obtained from BALB c/BYJ mice immunized with purified membranes from M type 5 Streptococcus pyogenes. Two of the anti-streptococcal monoclonal antibodies were previously shown to cross-react with muscle myosin. In this study the monoclonal antibodies were reacted with tissue sections of normal human(More)
A murine model was developed to study the cell-mediated immune response of mice immunized with one of two live, avirulent forms of Cryptococcus neoformans: a nonencapsulated mutant and a thinly encapsulated pseudohyphal variant. A lymphocyte transformation assay was used to evaluate the cellular response of control and sensitized spleen cells after in vitro(More)
Mice were immunized with a viable, avirulent strain ofCryptococcus neoformans. Lymphocyte blastogenic assays showed a 10-fold increase in reactivity of sensitized spleen cells, and histopathologic examination revealed marked splenic hyperplasia. Thirty-two days after intravenous inoculation with a virulent strain ofC. neoformans, none of the control animals(More)
An alkali-soluble water-soluble extract of Blastomyces dermatitidis yeast-phase cell walls was tested for its ability to elicit a response in lymphocytes isolated from the peripheral blood of Blastomyces-infected guinea pigs. Sequential preparations of the antigen were reproducible and specific in the in vitro lymphocyte transformation assay.(More)
An alkali-soluble, water-soluble cell wall fraction of Blastomyces dermatitidis, designated B-ASWS, was evaluated as an antigen for detecting in vivo (skin tests) and in vitro migration inhibition factor (MIF) production and lymphocyte transformation (LT) responses in Blastomyces-infected guinea pigs. The biological activity of B-ASWS was compared with that(More)
Infection with group A streptococci has been implicated as a factor capable of exacerbating psoriasis. In order to explore the possibility of cross-reactivity between streptococcal antigens and human skin in this phenomenon, skin from psoriatic patients and control subjects was reacted with 3 monoclonal antibodies against group A streptococci and antibody(More)
Subpopulations of spleen cells responsible for responsiveness and unresponsiveness to cryptococcal antigen in vitro were identified. Lymphocytes which responded in lymphocyte transformation (LT) assays were nylon wool nonadherent and theta antigen positive. These lymphocytes required the presence of an accessory cell which could be supplied by normal(More)
