Previous studies have shown the existence of a sphincter in the efferent filament artery of the teleost gill and its constrictory response to acetylcholine (ACH) and vagal stimulation. This study deals with the muscular organization of this sphincter

In order to evaluate the potential use of environmental scanning electron microscopy (ESEM) in biology, structural changes of the jejunal villi of rats were studied after periods of fasting and refeeding, using a conventional scanning electron micros

OBJECTIVES: Parenteral fat emulsions contain two populations of particles: artificial chylomicrons rich in triacylglycerols (TAG), and liposomes (bilayer of phospholipids [PL] enveloping an aqueous phase). Centrifugation permits isolating the liposom

Using an in vitro perfusion method, a morphofunctional study was made of single filaments isolated from the podobranch of the fresh-water crayfish Astacus leptodactylus. Each filament was fixed for transmission electron microscopy directly after an e

An ultrastructural study was performed on gill epithelia of the crayfish Astacus leptodactylus. The filament and the lamina of the podobranch were examined. In both structures a vascular system is lined by a specialized epithelium covered by a cuticl

A new method is described that allows in vitro perfusion and transepithelial electrical potential measurements of a single filament (3-5 mm long; 200 microns in diameter) isolated from the podobranch of the crayfish Astacus leptodactylus. An electrop

The aim of this work was to determine the kinetics of the dramatic development of the gill chloride cells (CCs) during adaptation of the salmonid Oncorhynchus mykiss to an ion-poor environment.To monitor cell division, the incorporation in the mitoti

Study of the distribution of neuroepithelial cells and neurons along the gill filament of rainbow trout (Oncorhynchus mykiss) showed that the density of neuroepithelial cells is maximal near the extremity of the filament, whereas the density of neuro

The distribution of the branchial nerves in the gills of the perch (Perca fluviatilis) and the rainbow trout (Oncorhynchus mykiss) was studied. Two nerve branches supply each gill arch: the first arch receives a posttrematic branch from the glossopha

Ependymal cells in culture and in vivo were treated with mixture of galactocerebrosides. Galactocerebroside is the major glycolipid of myelin and in demyelinating diseases is found in cerebrospinal fluid. Morphological changes induced by this treatme
