The objective of this study was to investigate the presence of anti-Leishmania spp. antibodies using an indirect immunofluorescence technique in the serum of equidae slaughtered in two slaughterhouses registered with the Federal Inspection Service. Titers greater than 40 were considered reagents. Blood samples were collected from 398 animals of both sexes, with different ages, and coming from six Brazilian states, of which 46.0% (183/398) were reactive, indicating that these animals were exposed to the leishmaniasis agent that is widely distributed in Brazil.

OBJECTIVE:To examine the presence of serum antinuclear autoantibodies in a healthy population. METHODS: Serum of 500 normal blood donors between 18 and 60 years of age were tested for the presence of autoantibodies. Antinuclear antibodies were detected by indirect immunofluorescence technique using HEp-2 epithelial cells as the substrate. The presence of dnaN was detected by indirect immunofluorescence technique using Critidia lucillae as the substrate. Anti-SSA (RO), anti-SSB (LA), anti-Sm, and anti-RNP were determined by double radial immunodiffusion. RESULTS: In the evaluation of the presence of serum antibodies, antinuclear antibodies were detected in 22.6% of the sera. The presence of other antibodies was not significant. The majority of the titers were 1:40. CONCLUSION: The presence of autoantibodies is not necessarily pathologic and has to be related to the age group, gender, and clinical condition of the patient.

Aggregation of adult rat hepatocytes, isolated by the collagenase perfusion technique, was studied by ultrastructural methods and the indirect immunofluorescence technique using anti-actin antibodies. In a primary culture the cells rapidly made contact with each other by filopodia-like structures, as seen by scanning electron microscopy. In a few hours this led to stable adhesion of the cells. No identifiable junction formation occurred during the first 17 h in culture. Within 48 h the cells had formed epithelial cell sheets with junctional complexes consisting of tight junctions, bile canaliculus-like structures and zonula adhaerens-type junctions. The distribution of cytoplasmic actin fluorescence remained homogenous in the contacting cells during the first 24 h in culture, as seen with anti-actin antibodies by the indirect immunofluorescence technique. The first short, fluorescent actin filaments appeared in the periphery of the developing lamellipodia of the spreading cell islands. In organized epithelial cell sheets these filaments were seen as long fibres ending at the perinuclear region of the marginal cells. In the submarginal cells fluorescent actin fibres were distinct at the junctional regions of the cells. This filamentous fluorescence seemed to extend throughout the entire cell sheet in an organized manner and correspond to the apical layer of parallel microfilaments seen in transmission electron microscopy. Our results suggest that filamentous actin plays a role in the contact-induced spreading of the cells and in the maintenance of the internal organization of the epithelial cell sheets.
