Intensity of acinus
hemocytic infiltration varied greatly, was stronger in females than in males (Table 4), and was likely positively correlated with gamete pathology.
For example, polymeric IgA, which is secreted by B-lymphocyte cells in close proximity to salivary cells, is then bound by IgA receptors present on acinus
cells, and then gets released into saliva (34).
1995), interstitial thickening in the central acinus
, and an increase in alveolar macrophages (Paige and Plopper 1999).
These data were supported by histopathology demonstrating an acute inflammatory response characterized by an influx of neutrophils into the central areas of the pulmonary acinus
, hyperplasia of the alveolar epithelium, and macrophage accumulation in the alveolar spaces.
Each liver acinus
is divided into three concentric zones of hepatocytes radiating from a portal triad and terminating at one or more adjacent terminal hepatic venules.
42,45,46) Such steatosis represents "true" fatty liver disease, which is recognized by the typical zonal pattern of steatosis (beginning in acinus
zone 3 and extending with increasing severity toward the portal tract), with or without classic steatohepatitis and steatofibrosis (Figure 5, B).
Spermatocytes are distributed in centripetal pattern from the acinus
walls to the lumen.
The etiology of these alterations is uncertain and could be secondary to the inflammatory injury or perhaps related to direct and/or indirect (via the degree of lung injury) stimulation of irritant C-fibers in the tracheobronchial tree and/or vagal non-myelinated fibers in the pulmonary acinus
(Costa and Schelegle 1999).
Complementary distribution of carbamoylphosphate synthetase (ammonia) and glutamine synthetase in rat liver acinus
is regulated at a pretranslational level.
The spermatogonia are attached largely to the acinus
