Disease relevance of periodic acid

• Periodic-acid Schiff and acid fast stains revealed no organism within the granulomas [1].
• RESULTS: Thickening of arterial walls with fibrosis, eosinophilic Periodic acid Schiff-positive basement membrane material and loss of vascular smooth muscle cells (VSMC) in the central retinal artery and its branches, the leptomeninges, the ocular adnexa, and the optic disk were observed [2].
• METHODS: Four cases diagnosed with microsporidiosis on Hematoxylin and Eosin and Periodic Acid Schiff's stained sections of the corneal button between January 2002 and December 2004, were included [3].
• For studies of experimental myocardial infarction, staining for phosphorylase and Periodic Acid Schiff outlined the ischemic area and antibodies against plasma fibronectin and fibrinogen delineated the infarcted myocardium [4].

High impact information on periodic acid

• Both ISS and corticosteroids significantly reduced levels of interleukin-5 in BAL, as well as the number of Periodic Acid Schiff-positive airway epithelial cells [5].
• Contiguous transverse sections were stained for mast cell tryptase and neutrophil elastase, and with Periodic Acid Schiff solution to identify mucus [6].
• Cells were stained histochemically for glycogen and mucin with Periodic Acid Shiff and Alcian Blue. RESULTS: Pig urothelium has a comparable structure to that of man: transitional epithelium comprising 4 to 5 cell layers [7].
• Periodic acid abolished functional activities of CR1, whereas trypsin and heat did not, indicating the functional significance of the carbohydrate moiety [8].
• Each specimen was embedded in paraffin wax at 90 degrees to the surface epithelium and 5 microm thick sections prepared for staining with haematoxylin and eosin, Periodic acid Schiff and Masson-trichrome at a step-serial interval of 100 microm [9].

Biological context of periodic acid

• The specimen was submitted for histology and after fixation in formalin solution and inclusion in paraffin, 3-5 mum sections were stained with hematoxylin and eosin for conventional evaluation and Periodic acid Schiff stain [10].

Anatomical context of periodic acid

• Periodic acid Schiff's base staining for carbohydrates stained dextrans in denervated muscle fibers [11].
• Periodic acid-induced blastogenesis of lymphocytes is independent of phosphoinositide turnover [12].
• The amount of soluble mucus in the gastric juice was estimated using Alcian Blue dye binding of acidic glycoproteins and Periodic Acid Schiff reaction with neutral glycoproteins [13].
• Using Periodic Acid Schiff-haematoxylin the intracellular neutral mucus of the goblet cells stains a brilliant, bright pink and the cell nuclei dark blue making it possible to observe the epithelial cells and the goblet cell population [14].
• Periodic acid Schiff-positive, diastase-resistant pigment was observed in the macrophages lining the sinusoids [15].

Associations of periodic acid with other chemical compounds

• Endogenous peroxidases were inactivated in four ways: (1) 0.3% hydrogen peroxide (H2O2); (2) 1% periodic acid (PA) (pH 1.85-1.95); (3) sodium meta-periodate (10-40 mM, pH 4.5); or (4) HCl (pH 1.80) [16].
• Differential diagnosis by microscopic analysis is based on pattern analysis, PAS (Periodic Acid Schiff) staining to rule out fungal infection, and immunohistochemistry to characterize lymphocytic infiltrate [17].
• Sections were stained with routine (hematoxyline and eosin), special (Masson Trichrome, Gordon, Periodic Acid Schiff, Aldehyde Fuchsin, and Orcein stains), and immunoperoxidase stains (using monoclonal antibodies for B and T cells and CD68 macrophages) [18].
• I-L with phenylbutazone or aspirin prevented the abolishment of Hematoxylin-Eosin, Periodic Acid Schiff and Alcian Blue staining polysaccharides from the stomach epithelial cells [19].
• The stains used were Haematoxylin and Eosin, Periodic acid schiffs, Alcian blue--Periodic acid schiffs (pH 2.5), Orcein--Alcian blue and Periodic acid sodium borohydride saponification [20].

Gene context of periodic acid

• Periodic acid treatment of the tissue section decreased reactivity with 2F9 antibody, but heat, neuraminidase or protease treatment did not [21].
• This study compared a panel of three different prion protein antibodies with conventional plaque staining methods--Congo Red, Periodic acid Schiff and sulphated Alcian blue--to investigate amyloid plaque formation in cases of human spongiform encephalopathy (HSE) [22].
• Periodic acid Schiff-positive non-glycogenic globules in hepatocytes. Differential diagnostic aspects in screening for alpha-1-antitrypsin globules in an autopsy material [23].
• Succinic dehydrogenase, myosin adenosine triphosphatase (mATPase at pH 9.4), nicotine adenonine dinucleotide reductase, and Periodic Acid Shiff histochemical stains were performed on plantaris and soleus muscles [24].

Analytical, diagnostic and therapeutic context of periodic acid

• Periodic acid-silver methenamine staining of semithin epon sections for phase contrast microscopy [25].
• Liver and intestinal sections, fixed in formalin-Millonig and embedded in paraffin, were stained with hematoxilin and eosin, PAS-Alcian Blue, pH = 1.0 and 2.5, Lennert's Giemsa, Picrosirius plus polarization microscopy, Periodic acid methanamine silver, Gomori's silver reticulin and resorcin-fuchsin [26].
