Responses of a recently developed rat alveolar macrophage cell (NR8383.1) line were compared to those of freshly derived alveolar macrophages in vitro. Marked inter- and intraspecies heterogeneity in levels of phagocytosis of unopsonizedPseudomonas aeruginosa or zymosan was noted among freshly derived alveolar macrophages from rats, rabbits, and baboons. In(More)
Over the course of the HIV epidemic, the demographics of the populations of affected individuals have changed. Groups that traditionally have been underserved in systems of care have a number of unmet service needs. This article presents results based on data from 478 patients in five national demonstration projects which were funded to enroll individuals(More)
The prevalence of Chlamydia trachomatis, a sexually transmitted disease, and the association of selected behavioral risk factors were assessed in a population of adolescents in two juvenile detention facilities. Urine was collected for Chlamydia testing and a brief interview conducted for risk and demographic information. Almost all of the 200 participants(More)
In the United States the risk of lead exposure is far higher among poor, urban, and immigrant populations than among other groups. And even slightly elevated blood lead levels increase children's risk of significant neurobehavioral problems extending through adolescence. Research has shown that blood lead levels in pregnant women well below the Centers for(More)
Poor, urban, and immigrant populations are at far greater risk for lead exposure than are other groups in the United States. Children with even slightly elevated blood lead levels are at increased risk for significant neurobehavioral problems that can extend through adolescence. Research has shown that elevated blood lead levels in pregnant women, even(More)
A rat pulmonary alveolar macrophage (PAM) cell line (NR8383) was initiated in culture in the presence of a gerbil lung cell conditioned medium (GLCM), and has been propagated continuously for over 36 mo. When examined at different times throughout this in vitro period, NR8383 exhibited characteristics typical of macrophages: (a) Zymosan ingestion was seen(More)
There is evidence that alveolar macrophages (AM) play a role in the clearing of Pneumocystis carinii from the lungs. To investigate the mechanisms involved in this process, we studied in vitro the induction of an oxidative burst by P. carinii in a cell line of macrophages (NR8383) and AM from normal rats. P. carinii was added to macrophage monolayers (10(6)(More)
Lung infections are a major source of morbidity and mortality in recipients of lung transplants. Prominent among the pathogens that cause pneumonias in these subjects are gram-negative bacilli, particularly Pseudomonas strains. One important reason that bacteria infect the lungs of these patients is that pulmonary defenses are impaired by the drugs used to(More)
This article develops a typology of 2,038 participants in 13 innovative HIV/AIDS treatment model service demonstration projects targeted to traditionally underserved populations. The typology is based on self-reported health-related quality of life levels. Eight clusters were identified that classify HIV/AIDS patients based on their reported health-related(More)
