Pepsinogen and HCl secretion in the amphibian stomach are performed by a single cell type, the oxyntopeptic cell. These functions were studied in gastric mucosae of toads (Bufo marinus) mounted in Ussing-type chambers. HCl and peptic activity of luminal fluid were measured by titration and proteolysis of albumin, respectively. Distribution of pepsinogen in(More)
Two adult ostriches developed anorexia, prostration, and severe hemorrhagic diarrhea, dying 24 hr after the onset of clinical signs. On postmortem examination, the cecal mucosa showed locally extensive areas of hemorrhages and fibrino-necrotic typhlitis with a white-yellowish material covering the mucosal surface. Multiple serosal petequial hemorrhages and(More)
Pepsinogen and HCl secretion in the amphibian stomach is performed by a single cell type, the oxyntopeptic cell. The distribution of pepsinogen in gastric mucosa of Bufo marinus is heterogeneous and higher concentrations are located in the fundus. Both secretions respond to the same secretagogues. Histamine induces the highest response for the two(More)
The perspectives of parents of private middle school students regarding the use of school-located immunization programs (SLIPs) are unknown. Parents of private middle school students in a large, urban setting were surveyed (N = 1,210) regarding their willingness to use SLIPs. Analyses included frequencies and chi-square analyses. Data from prior work with(More)
The professional process portfolio (PPP) was adopted by the Maternal Child and Health Bureau (MCHB) as an ‘innovation’ in best practice for all Leadership in Education and Adolescent Health (LEAH) Training Programs; however it had not been formally evaluated. Thus the objective was to evaluate the utility of the PPP for graduates of the LEAH training(More)
