Glycogen Particles

Embryonic amphibian cells when examined with the electron microscope were observed to contain an abundance of small particles, approximately 325 Å in diameter. The periodic acid/Schiff reaction and enzymic digestion were employed to determine the nature of the particles, and from the results of these tests they were concluded to be glycogen. Treatment of thin sections with periodic acid/lead citrate solutions resulted in a marked increase in contrast of the glycogen particles compared with other cell structures, and in a clearly defined substructure of 40-Å grains appearing within the particles. This differential staining method enabled the particulate glycogen to be distinguished from ribosomes.

Developing Muscle

The changes in muscle capillarity during postnatal growth have been difficult to study using standard histochemical methods. This laboratory has proposed the use of a lectin, Griffonia simplicifolia I (GSI), as a histochemical marker that may be appropriate for developing muscle. The purpose of the study was to compare the capillary densities (capillaries per muscle fiber) determined by the GSI lectin method, alkaline phosphatase-periodic acid-Schiff (APase-PAS) staining method, and by direct counting from 1-micron plastic sections. Sternomastoid muscles from 10-day or 6-wk-old rats were used. Results from the 10-day rats showed that the GSI method and the 1-micron method gave comparable results (1.44, 1.58 capillaries per fiber), which were significantly higher than that with APase-PAS (0.56). Capillary densities in the white region of the sternomastoid from 6-wk-old rats were identical (2.80) using both the GSI and APase-PAS methods. In contrast, the GSI method yielded significantly higher capillary densities in the red region than did the APase-PAS method (4.80 vs. 3.83). These results indicate that the GSI method for visualizing capillaries is a sensitive method for visualizing capillaries in muscle during the postnatal and juvenile growth period.

Mucinous Breast Carcinoma

BACKGROUND Detection of mucins has been shown to correlate with several clinicopathological characteristics in patients. Currently, periodic acid-Schiff (PAS) and alcian blue staining methods are the histochemistry staining techniques that are frequently used to detect mucin. This study was aimed to evaluate PAS and alcian blue staining in differentiating mucin characteristics between invasive carcinoma of no special type (ICNST) with mucinous degeneration and mucinous carcinoma. METHODS This cross-sectional study of 33 cases included biopsies of mucinous breast carcinoma and ICNST with mucin degeneration that were histologically verified using hematoxylin and eosin (H&E) staining. The PAS and alcian blue staining were conducted in the Laboratory of Histochemistry, Department of Anatomical Pathology, Cipto Mangunkusumo Hospital. Data were recorded using SPSS software, version 21 (IBM Corp, USA). RESULTS There were 17 cases of ICNST with mucinous degeneration and 16 cases of mucinous carcinoma with age varied from 27 to 75 years. PAS had sensitivity of 87.5% and specificity of 41.2%. Alcian blue had sensitivity of 43.8% and specificity of 82.4%. CONCLUSIONS PAS staining method is better than the alcian blue staining method in distinguishing between ICNST with mucinous degeneration and mucinous carcinoma. In the limited setting laboratory, PAS staining alone can be considered to detect mucin.

Parotid glands were obtained from five adult (four male and one female) armadillos (Dasypus novemcinctus) which were perfusion-fixed. The glands were located in a position similar to that of most mammals. They extended interiorly to the anterior portion of the submandibular gland.In the light microscope, it was noted that the acini were relatively small and stained strongly positive with the periodic acid-Schiff (PAS) and alcian blue techniques, confirming the earlier results of Shackleford (1). Based on these qualities and other structural criteria, these cells have been classified as seromucous (2). The duct system was well developed. There were numerous intercalated ducts and intralobular striated ducts. The striated duct cells contained large amounts of PAS-positive substance.Thin sections revealed that the acinar cells were pyramidal in shape and contained a basally placed, slightly flattened nucleus (Fig. 1). The rough endoplasmic reticulum was also at the base of the cell.
