Serosal membranes (pleura, pericardium, peritoneum). Normal structure, development and experimental pathology.

This monograph offers a comprehensive review of the present knowledge of the structure of the serosal coverings of the pleural, pericardial, and peritoneal cavities in humans and laboratory animals. The authors provide data from their own research--with transmission and scanning electron microscopy--on the structure of the main components of the serosal membranes: mesothelial cells, underlying basal lamina, and submesothelial connective tissue layer. Two main types of mesothelial cells (flat and cubic) are distinguished and their distribution on the parietal serosal sheets and on the visceral

Clinical anatomy of the pelvic floor.

The study presented here comparing cross-sectional anatomy of the fetal and the adult pelvic connective tissue with the results of modern imaging techniques and actual surgical techniques shows that the classical concepts concerning the subdivision of the pelvic connective tissue and muscles need to be revised. According to clinical requirements, the subdivision of the pelvic cavity into anterior, posterior, and middle compartments is feasible. Predominating connecting tissue structures within the different compartments are: Paravisceral fat pad within the anterior compartment (Fig. 17, I), re

The human nasolacrimal ducts.

The human nasolacrimal ducts are a borderland of the disciplines ophthalmology and otorhinolaryngology, which work close together in the treatment of nasolacrimal disorders. However, little knowledge exists concerning the physiology of the nasolacrimal system and, therefore, its pathophysiology. The aim of the present investigations was to obtain a better understanding of tear flow physiology, microbial defence strategies and pathophysiological processes by analysing the nasolacrimal system, thus opening new perspectives against existing therapeutical concepts of diseases of the nasolacrimal d

Histophysiology of the obesity-diabetes syndrome in sand rats.

Insulin, glucagon, somatostatin, and PP cells were found by immunotopochemical and electron-optical techniques in the islets of Langerhans of the sand rat, proving that the islets in this species also contain the four basic cell types known to be found in the islets in mammals in general. The ratio of A cells to B cells was 1:4 (19.1% A cells to 80.9% B cells). The pancreas of the sand rat contained assemblages of various numbers of neurons in the intralobal and interlobular connective tissue. They did not seem related in any regular fashion to specific blood vessels or branches of the pancrea

Cytokeratins in intracranial and intraspinal tissues.

The intermediate filament distribution pattern in cells and tissues of vertebrates reflects their differentiation or functional specialization state, their histogenesis, and their malignant transformation. In the case of cytokeratins, the characteristic epithelial intermediate filaments representing a complex group of about 30 polypeptides, extensive attention has been given to their expression in diverse epithelial and epithelioid cells. However, little is known about their distribution during fetal development and in neuroectodermal cells. This review specifically focuses on the data concern

A Case Report of Sebaceous Filaments.

This report details a case of a 16-year-old African American girl who presented with a two-year history of white spicules on her face without associated symptoms, including pruritus or pain. On physical examination, there were many 1-2 mm discreet white to yellow filamentous spicules on the mid and lower face. Histopathology scrapings showed cornified cells and calcification consistent with sebaceous filaments. Sebaceous filaments are a rare condition that presents as white-to-yellow spicules distributed in highly sebaceous areas on the face. It is caused by sebum accumulation and cornified ke

Pancreatic Proteolytic Enzymes and Cancer: New Support for an Old Theory.

In 1905, the embryologist John Beard first proposed that pancreatic proteolytic enzymes had potential as a treatment for cancer. His theories were dismissed by the medical world a decade later, but various practitioners have kept the concept alive through the publication of case reports of cancer patients treated with pancreatic proteolytic enzymes. In the last 2 decades, studies of the role of proteases in physiology have made it clear that they do more than digest food. This article reviews the history of the clinical use of pancreatic proteolytic enzymes in cancer treatment, and recent rese

Insights into Endothelial Progenitor Cells: Origin, Classification, Potentials, and Prospects.

With the discovery of endothelial progenitor cells (EPCs) in the late 1990s, a paradigm shift in the concept of neoangiogenesis occurred. The identification of circulating EPCs in peripheral blood marked the beginning of a new era with enormous potential in the rapidly transforming regenerative field. Overwhelmed with the revelation, researchers across the globe focused on isolating, defining, and interpreting the role of EPCs in various physiological and pathological conditions. Consequently, controversies emerged regarding the isolation techniques and classification of EPCs. Nevertheless, th
