This study assessed the presence of sialic acid α-2,3 and α-2,6 linked glycan receptors in seven avian species. The respiratory and intestinal tracts of the chicken, common quail, red-legged partridge, turkey, golden pheasant, ostrich, and mallard were tested by means of lectin histochemistry, using the lectins Maackia amurensis agglutinin II and Sambucus nigra agglutinin, which show affinity f...

Carbohydrate residues were localized in the glandular cells of the epidermis of Lumbricus terrestris by lectin histochemistry. The following biotinylated lectins were used: ConA, PNA, WGA, UEA-I. Each lectin has a specific binding pattern in the epidermal glandular cells. The ConA binding is evident in the orthochromatic mucous cells; PNA in the metachromatic mucous cells; WGA in the neuroendoc...

INTRODUCTION Colonic lesions are predominant in patients with schistosomiasis. However, carbohydrate alterations in colonic schistosomiasis remain unclear. Lectin-ligands allow us to identify changes in the saccharide patterns of cells. METHODS Biopsies of descending and rectosigmoid colon of patients were submitted to WGA and Con A lectin histochemistry. RESULTS WGA stained stroma and glan...

Up to now, histochemical investigations of the goblet cells found in cases of postoperative maxillary cysts (POMC) have yielded somewhat variable results, while examinations of glycoproteins have been restricted to only a few methods. Recently, lectins, which have specificity for various carbohydrate residues, have been applied for the detection of glycoproteins. However, as far as the author i...

The aim of this study was to examine the distribution glycoconjugates in conjunctival epithelium partridge (Alectoris chukar) and quail (Coturnix coturnix). Eyelid samples harvested from both species were subjected routine tissue processing. Lectin histochemistry applied sections order demonstrate expression glycoconjugates. Six different HRP-conjugated lectins (Con A, UEA-I, PNA, HPA, MAA BSA ...

The Chinese drug Bombyx Batryticatus mori.L which also named as the white stiff silkworm is widely used in clinics, due to the significant antispasmodic and promotional blood circulation effects. In addition, its hypoglycemic effect is also recognized in recent years. From a pathological point of view, the enzymatic glycosylation and non-enzymatic glycation both have important roles in regulati...
