The serum of 102 pigeon breeders was examined for circulating IgG antibodies against antigens localized in pigeon intestine by the indirect immunofluorescent technique. 15 symptomatic breeders with a positive response to inhalation challenge had antibodies against mucosa tissue. The majority of asymptomatic breeders demonstrated either a fluorescence of intestinal excrements combined with a weak fluorescence of mucosa tissue or had no detectable antibodies in their serum. By the indirect immunofluorescence, antibodies were found more frequently than by immunoprecipitin reactions in agar.
The possibility of ventricular arrhythmia and a prolonged QT-period in the ECG should be taken into account for patients diagnosed with celiac disease, especially in case of electrolyte imbalance. In these cases addition to a strict gluten free diet a rapid correction of the electrolyte imbalance is necessary because of the risk of sudden cardiac death. Furthermore associated disorders like autoimmune diseases expressing the same HLA-antigens (HLA-B8 and HLA-DR3) must be considered. Combined incidence of celiac disease and autoimmune hypothyroidism is well documented. For patients with celiac disease we therefore recommend a routine testing of thyroid hormone levels.
The labelling index in chronic nonspecific prostatitis ranges from 0.7-2.1%. This value is markedly higher than in nodular hyperplasia (0.4%) as well as in differentiated adenocarcinomas (0.6%). Increased labelling index could only be determined in glands adjacent to inflammatory foci. In recognition of these findings we believe that a correct evaluation of the cell proliferation in chronic prostatitis is only possible if each single cell can be evaluated, whether it is altered by inflammation or not. Therefore, solid tissue biopsies appear to be more suitable in autroadiographical studies than cytological material alone.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
