Abstract The Harderian gland of 110 laying hens was histologically investigated from the time of hatching to the period of 10 months of age. Tissue sections were stained with haematoxylin and eosin, periodic acid-schiff (PAS) and methyl green-pyronin technique. The research shows that lymphoid tissue is colonised by three types of cells: heterophils, lymphocytes and plasma cells. The number of these cells is directly dependent on the bird’s age. During the lifetime of the hens there gradually comes a shift in the dominance of these three cell types. Lymphoid nodules are detected only in 40-day-old chickens, while later in adult birds the Harderian gland is the organ which contains the largest number of mature plasma cells. Some plasma cells contain Russell bodies with different size and shape.

Native Chickens

  The objective of this investigation was to study the histological and histochemical structure of the Harderian gland in native chickens. Samples were obtained from 10 male and 10 female adult healthy native chickens. Tissue sections were stained with haematoxylin eosin, Verhoeff’s, Masson’s trichrome, alcian blue (pH 2.5), periodic acid-Schiff and Gomori’s method for reticulum. The multilobular Harderian gland of native chickens was covered by a thin connective tissue which consisted of adipose tissue, parasympathetic ganglia, nerve bundles, collagen, elastic and reticular fibres. Plasma cells were present in interlobular areas. The Harderian gland was compound tubulo-alveolar type. The Harderian duct was lined by columnar epithelial cells of varying height. Goblet cells were not found in Harderian duct. Histochemical staining revealed that the all epithelial cells of both corpus glandulae and ducts contained both neutral and acidic mucins. No significant sex-based differences were found. It is concluded that the general histological and histochemical structure of the Harderian gland in native chickens is similar to that of domestic geese, but that there are also some differences.

The objective of this investigation was to study morphological aspects of the Harderian, paraorbital, gland in domestic geese. Tissues were obtained from 9 male and 9 female adult domestic geese and processed for light microscopy. Tissue sections were stained with Mallory’s trichrome, silver impregnation, methyl green-pyronin, periodic acid Schiff, alcian blue (pH 2.5), alcian blue/periodic acid Schiff (pH 2.5) and Sudan black B staining techniques. Results revealed the Harderian gland of domestic geese was covered by a capsule, which contributed trabeculae that divide the organ into lobes and lobules. The glandular epithelium was multilobular, compound tubuloalveolar. The secretion of Harderian gland was mucous and the secretion type was apocrine; the gland emptied to the inner surface of the nicticating membrane by a single duct.

Abstract Dutcher bodies are periodic acid-Schiff–positive intranuclear pseudoinclusions found in plasma cells in mucosa-associated lymphoid tissue lymphoma, Waldenstrom macroglobulinemia, and myeloma. We describe the case of a 68-year-old woman with chronic synovitis containing multiple Dutcher bodies. The patient's workup for lymphoma was negative. Hematoxylin-eosin– and periodic acid-Schiff–stained sections of 7 cases of marked chronic synovitis selected from the files spanning a 10-year period at Memorial Hospital of Rhode Island (Pawtucket, RI) were examined, and none showed Dutcher bodies. This case illustrates that Dutcher bodies may rarely occur in benign reactive conditions, such as chronic synovitis.

A light and electron microscopic study of the enterocytes and gut-associated lymphoid tissue (G ALT) of the flounder Platichthys flesus showed regional differences in the structure of the epithelial cells. Epithelial villi decreased in height and spatial complexity, but increased in overall thickness in the posterior intestine. There were no specialized cells comparable with mammalian M cells. Periodic acid Schiff (PAS) activity increased in the enterocytes and goblet cells in the anterior intestine where alkaline phosphatase activity was most pronounced in enterocytes. Adjacent cells were joined by tight junctions.Gut-associated lymphoid tissue was composed of isolated leucocytes in the epithelium and lamina propria with no accumulations. Numbers of intra-epithelial leucocytes were not statistically different in the various regions of the intestine. Five leucocyte types were distinguished among the gut-associated lymphoid tissue although lymphocytes and granulocytes were the most common. Granulocytes were positive for the Romanowsky stains with PAS/Alcian blue positive granules. Blast cells similar to large lymphocytes were unevenly distributed through the different regions of the intestine. Plasma cells were more numerous in the epithelium than in the lamina propria. Macrophages were rarely detected.

AbstractPathology is practiced by visual inspection of histochemically stained tissue slides. While the hematoxylin and eosin (H&E) stain is most commonly used, special stains can provide additional contrast to different tissue components. Here, we demonstrate the utility of supervised learning-based computational stain transformation from H&E to special stains (Masson’s Trichrome, periodic acid-Schiff and Jones silver stain) using kidney needle core biopsy tissue sections. Based on the evaluation by three renal pathologists, followed by adjudication by a fourth pathologist, we show that the generation of virtual special stains from existing H&E images improves the diagnosis of several non-neoplastic kidney diseases, sampled from 58 unique subjects (P = 0.0095). A second study found that the quality of the computationally generated special stains was statistically equivalent to those which were histochemically stained. This stain-to-stain transformation framework can improve preliminary diagnoses when additional special stains are needed, also providing significant savings in time and cost.

Human Anterior Pituitary

Human anterior pituitary tissue that had been removed at operation and immediately fixed was examined by a number of cytological and histochemical methods and by phase contrast and electron microscopy, and compared with similar material obtained post mortem. The general histological picture of good post-mortem material (not more than 4 hours post mortem) compared well with the surgically-removed tissue. For the study of silver impregnations of the Golgi substance, however, material removed at operation was found to be greatly superior. Evidence was obtained showing that the intracellular lipid inclusions seen post mortem were not artifacts resulting from cytolytic changes. There appeared to be no relationship between these lipid bodies and the Golgi material as revealed by the Aoyama method. No unequivocal dimorphism of the Golgi bodies, correlated with α- and β-cells, such as has been reported to occur in certain other mammals, was observed. Phospholipid was present in the granules of a substantial proportion of the α-cells. It was found that most of the cells which had been designated as β-cells after the application of certain routine staining methods, and most of the Gram-positive cells, reacted positively to the Periodic acid Schiff test: these cells could therefore be regarded as true β- or mucoid cells. A method for the demonstration in frozen sections of the cell-types, together with the lipid inclusions, is described.

The Third

Three patients with plasma cell leukemia are reported. Two of them had a previous history of myeloma; the third one started with a plasma cell leukemia. Diagnosis was made from the required presence of 20% plasma cells in the peripheral blood. In all 3 cases, bone marrow aspiration and peripheral blood showed plasma cells strongly positive for acid phosphatase and alpha-naphthyl acetate esterase, and negative for periodic acid-Schiff. The first patient was treated with a polychemotherapy regimen that included vincristine, cyclophosphamide, chlorambucil and prednisone, and the second patient with melphalan and prednisone; the third one, who started with plasma cell leukemia, received total body irradiation at the dose of 600 rad. The results of the therapy and survival time, which was never more than 3 months, are in accord with other reports in the literature.

I): The degree of inhibitory effect of serum proteins and a periodic acid Schiff-positive amyloid fraction on metachromasia resulting from a metachromatic amyloid fraction was studied and compared to the metachromatic potency of chondroitin sulfate exposed to the same type of inhibition. The metachromatic properties of chondroitin sulfate were close to those of the metachromatic amyloid fraction. II): In comparing the metachromasia obtained with toluidine blue and methyl violet, it was noted that on incubation with the periodic acid Schiff-positive amyloid fraction, amyloid metachromosia after methyl violet staining was inhibited less than after toluidine blue staining. III): It is emphasized that a competition between dye and proteins occurs in metachromatic staining reactions. IV): Inhibition of amyloid metachromasia in histological tissue sections could not be demonstrated with the techniques used.

Red Coloration

Abstract Histologic and histochemical study of the foam cell in the spleen in thalassemia has shown that the foamy appearance is due to the accumulation of an acidic mucopolysaccharide of the chondroitin sulfuric acid type in the cytoplasm of this histiocytic cell. This polysaccharide shows intense red coloration with the periodic acid Schiff reaction, which is thus of great value in demonstrating the foam cell in tissue sections. The possible sources of this mucopolysaccharide have been discussed.

Proliferating Cell

Abstract Single and multiple injections of tritiated thymidine were combined with radioautography to study the rates of proliferation and interrelationships of the various cell lines in the mesenteric lymph node of the rat. The appearance and labeling patterns of the different cells are described from studies of both smears and tissue sections. Reticular cells exhibit wide variations in labeling intensity, phagocytize labeled lymphocytes, and become labeled in high percentages only when TTH is administered over a period of many days. Other slowly proliferating cell types include small lymphocytes, fat cells, endothelial cells and mast cells. Rapidly proliferating cell lines include plasmablasts, hemohistioblasts, proplasmacytes and large lymphocytes. The generation time of plasmablasts and hemohistioblasts was determined to be approximately 9 and 12 hours respectively. Mature plasma cells constitute a non-dividing population which is renewed in lymph node in not more than 5 days. Evidence is presented that the most primitive cells in the lymphocyte and plasma cell lines are the hemohistioblasts and plasmablasts respectively. Reticular cells most probably are not stem cells. No evidence is found to support previous reports that plasma cells derive from lymphocytes.
