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...

During the development of the proventriculus (glandular stomach) of the chicken embryo, the endodermal epithelium invades into the surrounding mesenchyme and forms glands. The glandular epithelial cells produce pepsinogen, while the non-glandular (luminal) epithelial cells secrete mucus. Sonic hedgehog is expressed uniformly in the proventricular epithelium before gland formation, but its expre...

The glandular odontogenic cyst is an uncommon developmental odontogenic cyst described as a distinct entity by Gardner et al. in 1988. The Glandular odontogenic cyst occurs more commonly in middle-aged people and has a predilection for the mandible. Only histopathological examinations allow for certain diagnosis of the cyst. The increased recurrence rate can be due to its multilocularity and in...

Acinic cell carcinoma (ACC) of the breast is extremely rare and is characterized by widespread acinar cell-like differentiation. We report of a 39-year-old woman presented with a palpable breast mass with significant morphological, immunohistochemical and ultrastructural findings. Histologically, ACC showed a diffuse glandular infiltrative pattern, with small acinar or glandular structures mixe...

Glandular Odontogenic Cyst is a relatively rare cyst of odontogenic origin, which shows glandular or salivary features that are thought to indicate the pluripotentiality of odontogenic epithelium. It is seen in middle-aged adults, and commonly involves the anterior region of the jaws, especially the mandible. It shows non-specific clinico-radiographic findings which may resemble other lesions, ...

Trichomes are epidermal hairs found on the aerial surfaces of nearly all plants and in different species. They grow in different shapes and act as protectors against insects, microbes and herbivores. Trichomes vary in their morphology, distribution pattern on a given organ and in their histochemical images. Different trichome types were observed in the aerial parts of the two species of broomra...

Colorectal adenomas are foci of dysplastic mucosa that may antedate the development of a colorectal cancer. In this work we investigated 62 colonic polyps. A close examination revealed that in some adenomatous glands facing the muscularis mucosa a group of dysplastic cells were missing. Those glandular defects were connoted as glandular pores. Many glands with pores were dilated and had retaine...

Hitherto characters derived mostly from macromorphology were used to distinguish among the members of Acanthopsis Harv., a taxonomically difficult group plants endemic arid parts southern Africa. The taxonomic significance leaf and bract indumentum in was investigated using light, scanning electron microscopy. Five non-glandular three glandular trichome types distinguished on leaves floral brac...

Abstract The leaves of different species the genus Artemisia show considerable inner and external structural diversity. This paper presents a comparative study micromorphological features leaf surface for seven from regions Ukraine: A. absinthium L., annua dracunculus marschalliana Spreng., vulgaris argyi H.Lév. & Vaniot, verlotiorum Lamotte. vegetative organs these plants have potentially ...
