Morphometric Features and Microanatomy of the Lingual Filiform Papillae in the Wistar Rat.

The mammalian tongue plays a fundamental role in various physiological and behavioral activities. Significant morphological variations have been recorded in the tongue of several species. This study aims to obtain detailed histological and morphometric information about the filiform papillae on the surface of rat tongue.

Mucous non-goblet cells in the small intestine of guinea pigs (Cavia porcellus): a histological and histochemical study.

Background: The covering and glandular epithelium of the small intestine in guinea pigs (Cavia porcellus) include some mucus-secreting cells. Goblet cells are specific cells for mucus secretion with a distinctive cup-like appearance due to the accumulation of mucin in the apical pole. The deep crypt secretory (DCS) cells were identified in a limited array of species and only recently were noticed in the large intestine in mice, guinea pigs, humans, monkeys, and pigs.

The pioneer use of a modified PRGF-Endoret® technique for wound healing in a hemodialyzed diabetic patient in a terminal stage of renal disease.

In the literature, this paper is the first to describe the use of plasma rich in growth factors (PRGF)-Endoret® in hemodialyzed diabetic patients, to promote the healing of after amputation wounds. The PRGF-Endoret® was primarily conceived to be used in maxillofacial surgery, oral implantology, etc., the innovation residing in the blood collection technique (quantity, moment of the week, rhythmicity), which was adapted to the specific conditions of the hemodialyzed patient.

Glandular structures in the major interlobular and extrapancreatic ducts in the guinea pig.

The morphology of the pancreatic duct system did not receive much attention as compared to the microanatomy of the exocrine and endocrine pancreas. The histological peculiarities of the excretory duct system are of major importance especially in laboratory animals like guinea pigs. The paper describes the histological peculiarities of the major interlobular and extrapancreatic ducts in guinea pigs.

A novel mitochondria-targeting method using special staining for the detection of apoptotic hepatocytes.

Early detection of apoptotic cells on histological slides is of major importance for both diagnostic and research areas. In the current study, the aim was to propose a convenient method to stain the mitochondria and establish whether hepatocytes undergoing apoptosis can be identified in tissue sections using the proposed method. Liver tissue from five adult chinchillas was fixed with 10% neutral buffered formalin for Goldner's trichrome (GT) and Groat's iron hematoxylin and eosin (HE) stains and with Kolster's fixative for the Heidenhain's iron hematoxylin procedure.
