In their series of 27 biopsies from 18 patients whose C4d was stained with a formalin/IHC-IP method, they reported that C4d staining in interacinar capillaries (5% or more of capillaries staining) correlated with the presence of donor-specific antibodies, and that C4d labeling of arteries, veins, interstitial structures, or islets did not.
C4d-positive interacinar capillaries correlates with donor-specific antibody-mediated rejection in pancreas allografts.
Histological scoring of pancreatic tissue was performed to grade the extent of acinar cell vacuolization (0: none, 1: <20% acini with vacuoles, 2: <50% acini, 3: > 50% acini), edema (0: no edema, 1: interlobular edema, 2: intralobular edema, 3: interacinar
edema), inflammation (0: no inflammation, 1: interlobular inflammatory cells present, 2: intralobular inflammatory cells present, 3: interacinar
inflammatory cells present) and acinar cell necrosis (0: no necrosis, 1: < 10% necrosis, 2: < 40% necrosis, 3: > 40% necrosis).
Histomorphologically, the human BPH tissues showed hyperplasia of epithelial and stromal tissues, which were characterized by hyperplasia nodules, high cylindrical epithelial cells, irregular and dilation of acini with villous projections, back-to-back interacinar space, and ischesis (Figure 1A) .
Histologically, the prostate tissues of the rats in the BPH group showed atypical hyperplasia of epithelial and stromal tissues, which was characterized by irregular acinar shape with villous projections, dilation of acini, high cylindrical epithelial cells, back-to-back interacinar space, and ischesis (Figure 2C) .
2D, F, I): a) gametogenic or acinar; b) perigametogenic or periacinar and c) intergametogenic or interacinar.
The gametogenic compartment is located among the tubules of the digestive gland; the acinus is its' basic morphological unit, having a globous appearance, and is found intimately interacting with the periacinar and interacinar compartments (Figs.
The interacinar compartment is formed of a matrix of vesicular somatic cells, forming a surrounding tissue, by which the other compartments are also surrounded (Figs.
Carcinoid tumors arise from a type of interacinar
cell that produces peptides and another type that produces 5-HT (5-hydroxytryptamine, or serotonin), which plays a role in regulating blood circulation and other basic functions, including sleep.
En el tejido conectivo interacinar se ubican vasos sanguineos y escasas fibras colagenas (Fig.
Los espacios interacinares presentan incremento del tejido conectivo, con predominio de las fibras colagenas.
