Correlated histochemical and autoradiographic studies were conducted on rat, rabbit, cat and dog salivary glands. Mucous acini of rat minor sublingual (SL) rabbit SL and cat posterior SL and submandibular (SM) glands were stained by Alcian Blue at pH 1.0, aldehyde fuchsin or the high iron diamine technique. The distribution of cells with this type of basophilia corresponded with that of cells shown autoradiographically to incorporate S35O4= and accordingly to contain sulfomucin. The lack of periodic acid-Schiff and alcohol-resistant metachromasia at pH 0.5 of rabbit SL mucin resembles connective tissue mucopolysaccharide. Some mucous acini of the dog posterior SL gland incorporate S35-sulfate and the distribution of isotope-labeled acini correlates with that of acini showing histochemical staining indicative of sulfomucin. The remainder of mucous acini in this gland do not show uptake of radiosulfate, but have alcianophilia that is reduced by sialidase digestion. All of the mucous acini of dog SM gland show correspondence of staining for sulfomucin with S35O4–, incorporation. The seromucous demilunes of this gland manifest sialidase-labile alcianophilia. The staining of sulfomucin and S35 labeling in each of the salivary glands studied are eliminated by a 4-hr methylation at 60°C.

The effect of digestion with Streptomyces hyaluronidase upon certain histochemical reactions of hyaluronic acid-containing tissues has been studied in a series of human, mammalian and avian specimens. These histochemical reactions are those for the demonstration of neutral and sulfated and nonsulfated acid mucosaccharides such as periodic acid-Schiff, Alcian Blue (pH 1.0), azure A (pH 1.5), high iron diamine, aldehyde fuchsin, Alcian Blue (pH 2.5), Alcian Blue (pH 2.5)-periodic acid Schiff, azure A (pH 4.5), low iron diamine and colloidal iron. In addition, the effect of digestion with testicular hyaluronidase upon the same reactions of the same tissues was observed for comparison. Digestion with Streptomyces hyaluronidase diminishes the staining reactions due to hyaluronic acid but fails to affect those for neutral and sulfated acid mucosaccharides. These results indicate that digestion with Streptomyces hyaluronidase is a method of choice for the identification of hyaluronic acid in mucosaccharide histochemistry.

Luteinizing hormone (LH) was localized immunohistochemically to cells in the pars anterior and pars tuberalis of the human pituitary gland. Upon restaining with a variety of histochemical procedures, LH-containing cells were found to be aldehyde fuchsin and periodic acid-Schiff (PAS) positive; however, the intensity of histochemical staining failed to correlate with that of fluorescence. Only a few of the PAS- or aldehyde fuchsin-positive cells contained LH. In contrast to the above, with the performic acid-alcian blue-PAS-organge G sequence of Adams, all cells containing LH were turquoise colored, alcian blue-positive (S1 mucoid cells) and vice versa. This study was performed with antiserum specific for human chorionic gonadotropin which was shown to cross react in immunodiffusion analysis with purified human pituitary luteinizing hormone and to be capable of neutralizing its biological activity.

Abstract An unusual case of synchronous gastric carcinomas occurred in a 28-year-old man with a family history of gastric disease. Two tumor foci were identified: a well-differentiated advanced carcinoma with the phenotypic properties of complete intestinal metaplasia and an early intestinal-type carcinoma. Histochemical and immunohistochemical stains to demonstrate complete intestinal metaplasia, ie, Alcian blue pH 2.5/periodic acid–Schiff, high iron diamine/Alcian blue pH 2.5, CD10, and MUC2, were all positive in the advanced adenocarcinoma. Of all markers used, only high iron diamine/Alcian blue pH 2.5 and Alcian blue pH 0.5 were positive in the early carcinoma. In these cases, mistakes frequently are made during examination of endoscopic biopsies. Fortunately, the advanced adenocarcinoma was low grade (the patient has shown no signs of disease at 6 years postsurgery). Histopathologic, histochemical, and immunohistochemical findings suggest that an extensive substrate of complete intestinal metaplasia (corpus) and of complete and incomplete intestinal metaplasia (antrum) can be associated with two independent tumors with different phenotypes.

A method for demonstrating acidic polysaccharides in formalin fixed parafin embedded tissue sections using fluorescein labelled deacetylated chitin is described. Epithelial and connective tissue acidic polysaccharides have been studied in a number of organs. The distribution of acidic polysaccharides as seen with fluorescein-labelled deacetylated chitin is similar to results obtained with alcian blue-periodic acid Schiff and fluorescein-labelled Aspergillus polysaccharide. Previously reported fluorescent staining methods for acidic polysaccharides such as iron-hematoxylin-acridine orange and atabrine as well as fluorescein-labelled deacetylated chitin may prove to be useful adjuncts to the light microscopic methods of demonstrating mucins. Other possible uses of deacetylated chitin, a colorless macro-cation, in histochemistry and cytochemistry are noted.

A dermal mucinoisis, visualized as dermal alcianophilic material, is occasionally present in canine hypothyroidism (myxedema). Various histochemical reactions (alcian blue/periodic acid–Schiff [PAS], alcian blue at pH 2.6, alcian blue at pH 1.0, critical electrolytical concentrations with and without dimethylsulfoxide, differential hydrolysis by hyaluronidases) were performed on skin biopsies from six dogs (four females and two males ranging from 8 to 13 years) affected by hypothyroidism, all of them presenting dermal mucinosis in hematoxylin and eosin–stained sections. In these dogs, the only polysaccharide compound involved in the dermal mucinosis was hyaluronic acid. In this study, hyaluronic acid dermal deposits of hypothyroid dogs were significantly different from those of controls in subepidermal connective tissue and loose reticular connective tissue but not in periadnexal zones. We recommend the combined alcian blue/PAS reaction as a routine technique to assess dermal mucinosis in hypothyroid dogs.

Mucosubstances (MS) were examined in 10½-14½-day embryonic rat hearts utilizing nonaqueous fixatives or formaldehyde vapor-fixed frozen sections hydrated in concentrated solutions of cetylpyridinium chloride. Ribonuclease-resistant, polyanionic sites were limited to the extracellular cardiac jelly, endocardium and fibroblastic cells (cushion tissue) associated with the endocardium. The cardiac jelly and endocardium of day 10½ embryos principally contained a hyaluronic acid-like carboxylated mucosubstance whose alcianophilia at pH 2.5 was abolished by hyaluronidase but was resistant to NaOH extraction and neuraminidase and trypsin digestion. A critical electrolyte concentration of 0.2 M MgCl2 abolished alcianophilia. On days 13½-14½ carboxylated MS were restricted to cushion tissue and partially resisted mild methylation. Sulfated MS were limited to primitive endocardial cells which gave origin to cushion tissue. Dye deposits of aldehyde fuchsin, high iron diamine or Alcian Blue (pH 1.0) were localized on cell surfaces and such staining was prevented by strong (60°C) methylation. Hyaluronidase sensitivity of sulfated MS decreased with gestation. The critical electrolyte concentration varied from 0.5-0.7 M MgCl2 on days 11½-12½ to 0.8-0.9 M MgCl2 after day 12½. The sulfated MS of endocardial cells were preceded by a transitory accumulation of diastase-resistant, periodic acid-Schiff-positive material. Possible roles of MS in normal and abnormal cardiac septation processes are discussed.

Abstract Context.—We have observed intraluminal crystalloid morphology in seminal vesicles that is superficially similar to that seen in prostate neoplasia, but found little information on such morphology in the literature. Design.—Two hundred fifty-three prostate specimens (163 needle biopsies, 75 radical prostatectomies with prostate carcinoma, 11 prostates from autopsy, and 4 cystoprostatectomies without prostate carcinoma) were examined for seminal vesicle secretions, which were categorized as (a) dense platelike inspissated, (b) fluidlike, (c) crystalloid morphology, and (d) absent. Histochemical stains (periodic acid–Schiff with and without diastase, Alcian blue at pH 2.5, and mucicarmine) were performed to characterize the nature of secretions. Results.—Proteinaceous secretions were identified in 82% of seminal vesicles examined. Of these, 61% had predominantly dense, platelike, inspissated secretions, 15% had predominantly fluidlike secretions, and 24% had predominantly crystalloid morphology. Although in some cases the crystalloid morphology resembled that of prostatic intraluminal crystalloids, the seminal vesicle crystalloids differed in that they were invariably multiple, had curved edges, and had varied forms (elliptical, cylindrical, rodlike, and rectangular). Seventy-one percent of seminal vesicle crystalloids were associated with dense, platelike, inspissated secretions and appeared to be created by fracturing within platelike secretions. There was no relationship between seminal vesicle crystalloid morphology and associated malignancy in the prostate gland, as it was seen in 24% of cases with prostate carcinoma and 25% of cases without prostate carcinoma (P = 1.0000). Fluidlike secretions were positive for Alcian blue (pH 2.5) and mucicarmine, whereas dense platelike secretions and crystalloid morphology were negative for Alcian blue (pH 2.5) and mucicarmine. Conclusions.—Seminal vesicle secretions are fairly common and, when fluidlike, are composed of acid mucopolysaccharides. Inspissation of secretions appears to be associated with loss of acidity, presumably resulting in dense platelike secretions and crystallization. Awareness of both the crystalloid morphology in seminal vesicle tissue and the distinguishing features from prostatic crystalloids may be important while interpreting prostate needle biopsies in which seminal vesicle epithelium may be confused for prostate carcinoma because of a small acinar morphology with accompanying cytologic atypia and crystalloid morphology.

Larvae of the lamprey, Entosphenus lamottei (Le Sueur), and rainbow trout, Salmo gairdneri Richardson, were exposed to the sodium salt of 3-trifluormethyl-4-nitrophenol (TFM) in concentrations of 0.75 p.p.m., 3.00 p.p.m., and 6.00 p.p.m. Microscopic examination of changes induced in the gills, liver, cloacal region, and musculature were made on 7-micron sections stained with Harris' haematoxylin and Bowie's eosin, and in the gill region with periodic acid Schiff reagent. A comparison of the degree of the effects in the two species was made by planimetry of the vascular, cellular, and edematous areas from enlarged drawings of sections.Upon exposure to lethal concentrations of TFM, the body of the larval lamprey becomes distended at the pharyngeal level and heavy cords of mucus emerge from the external gill clefts. A deep red coloration is evident in the pharyngeal region consequent upon vasodilatation of the arterioles and capillaries of the gill filaments. Trout exhibit a similar vasodilatation of the gills together with increased mucous secretion. Edema in the connective tissue between the respiratory epithelium and the vascular endothelium is induced in both species. After prolonged exposure to TFM, the mucous cells in the lining of the branchial chamber and covering the tips of the gill filaments are actively discharging their secretions or completely spent.Certain effects induced by TFM in the larval lamprey are not evident in the trout. The cloacal region takes on a deep red coloration due to dilatation of the venous sinuses and the liver becomes reddish because of sinusoidal dilatation. Extensive edema of the fibrous connective tissue of the skeletal musculature is characteristically present. A slightly increased secretory activity of mucous-secreting cells may occur in the epidermis.With the techniques employed in this study, there was no evidence in either species of cytological or histological changes in the nervous tissue, cardiac musculature, notochord, alimentary canal (including the haemopoietic typhlosole of the lamprey), or mesonephros.

Background: This study was undertaken to evaluate the preferred method (Giemsa or periodic acid Schiff-Alcian blue [PAS-AB] stains) of detecting Helicobacter pylori (H. pylori) in gastric mucosal biopsies in terms of sensitivity, specificity and applicability. To the best of my knowledge, this is the first report comparing Giemsa and PAS-AB staining for the detection of H. pylori in such biopsies. Methods: The formalin-fixed paraffin-embedded blocks of 49 gastric biopsies from different patients were collected from the archive of anatomical pathology at King Abdulaziz Medical City, National Guard, Riyadh, Saudi Arabia. From each block, three slides were prepared and analysed using the hematoxylin and eosin (H&E), Giemsa and PAS-AB stains to detect the presence/absence of H. pylori, and the results were compared in terms of sensitivity, specificity and applicability. Results: The majority of the biopsies in this study showed antrum-type gastric mucosa. Only 15 biopsies showed active gastritis, whereas the rest showed chronic gastritis. Three biopsies showed intestinal metaplasia. All were detected by PAS-AB stain, but only two-thirds were detected by H&E stain. Fifteen gastric biopsies showed H. pylori infection in general and in 13 of them, active gastritis cases were discovered. Fourteen out of these 15 H. pylori infection cases were detected by Giemsa stain, whereas only 13 cases were detected by H&E stain. PAS-AB stain showed the worst results since it demonstrated only 40% sensitivity and 67.65% specificity in H. pylori detection. Conclusion: Giemsa stain has better sensitivity and specificity in gastric H. pylori infection detection than PAS-AB. Therefore, using PAS-AB stain to detect H. pylori infection is not recommended.
