Of 202 captive hares studied, many of which had lesions on their external genital organs or testicular atrophy or both, 27% had positive serological tests for syphilis although dark-field examination of extracts of atrophic testes was negative. A total of 12 hares that were nonreactive for the serological test for syphilis was inoculated with Treponema(More)
The topo-optical staining reactions characterized by oriented dye binding on micellar textures may reveal—by their birefringence effects—ultrastructural details in biological membranes not accessible to other biophysical-optical methods. In the present investigations the topo-optical staining reactions of blood cell membranes with toluidine blue were(More)
A genetic family study was undertaken by photofluorography of the first, second, and third degree relatives of 116 index patients with adolescent idiopathic scoliosis (AIS). The index patients were ascertained in the course of an epidemiological screening. The pattern of familial clusters and the recurrence risk related to the number of affected relatives(More)
A new two-step centrifugation technique is described for the rapid preparation of viable pure polymorphonuclear granulocytes from 9.5 ml of venous blood. The phagocytosis of these cells was stimulated by soluble DNA-anti-DNA complexes, produced in vitro by incubating high mol. wt. DNA with sera obtained from patients with severe SLE. The measure of(More)
TNFalpha is a highly active cytokine which plays an important role in the regulation of apoptotic cell death, a mechanism involved in the pathophysiology of myelodysplastic syndrome (MDS). In this study we investigated the expression of TNFalpha of the bone marrow trephine biopsies by immunohistochemical method and the TNFalpha production of peripheral(More)
Authors examined, using sonographic methods in 100 children with breech-presentation, which of the intrauterine postures means a major danger in the development of hip dysplasia. It was found that acetabular alterations, requiring therapy or not, develop more frequently in groups in which the hips were in total flexion, the knees in semiflexion and the(More)
