Objective(s):The aim of this study was to evaluate distribution and changes of glycoconjugates of retinal photoreceptors during both pre- and postnatal development. Materials and Methods: Tissue sections from days 15 to 20 of Wistar rat embryos and 1 to 12 postnatal days of rat newborns including developing eye were prepared for lectinhistochemistry technique. Horseradish peroxidase (HRP)-label...

Lectin peroxidase histochemical analysis was carried out on pancreatic tissue from patients with pancreatic carcinoma and chronic pancreatitis and from subjects with normal pancreas to find a tumour specific pattern of lectin binding that would aid histological and cytological diagnosis. There were striking differences between the lectin binding characteristics of the different cell types in th...

The aim of the present research was to investigate the changes of the sugar residues in the oviduct in the course of ageing in postmenopausal women vs normally menstruating women, by means of lectin histochemistry. Twenty asymptomatic postmenopausal women (48-83 years old) were recruited among patients who underwent a vaginal hysterectomy. Eight normally menstruating women were recruited as con...

A juvenile nephropathy in a 4-year-old male Boxer dog, closely resembling the Nephronophthisis (NPHP)-Medullary Cystic Kidney Disease Complex (MCKD) in humans is described. Gross examination of the kidneys revealed several multiple cysts at the corticomedullary junction and in the medulla. Histological examination was characterized by a widespread tubular atrophy and dilatation, with a marked t...

Previous studies have shown that epididymal epithelium and its secretions are critical for sperm maturation. These secretions contain many glycoconjugates with sialic acid terminal sugar. This terminal sugar by interveining in cellular interactions and masking surface receptors, has an important role in sperm maturation and protection. Moreover lectins have been employed as useful probes to det...
