Chemotaxis, random mobility, and mobilization of polymorphonuclear leucocytes in malnutrition.

Neutrophil mobilization following administration of Pseudomonas polysaccharide was significantly reduced in malnutrition, especially during infection. The random mobility of polymorphonuclear leucocytes (PMNs) was slightly decreased in undernutrition. Chemotactic migration of PMNs was depressed and correlated more with the presence of infection than with nutritional deficiency. It is possible that these abnormalities of PMN mobilization and mobility in malnourished individuals contribute to suboptimal amount, kinetics, and pattern of tissue inflammatory response to bacteraemic challenge.

Clinical evaluation of the sandpaper disk method for removing fluorosis stains from teeth.

The sandpaper disk method for removing fluorosis stains from teeth was clinically evaluated in 93 teeth in 22 patients. A bleaching solution was first applied to the teeth, and then a sandpaper disk in a straight handpiece was rotated on the stained enamel surface. None of the patients complained of discomfort during or after the bleaching procedure.

Ultrastructural characteristics of human neurilemoma cell nuclei.

Nuclei of human neurilemoma cells exhibit deep and extensive invaginations of part of their surface. Such invaginations contain cytoplasmic matter. However, in areas of the nucleoplasm distant from the invaginations, small membrane-bound bodies, some of which contain a "nucleoid," occur either singly or grouped together and enclosed within a large membrane body. These small bodies are not considered virus-like. Degenerated nuclei from cultured tumor tissue contain spherical bodies, 130 to 230 nm in diameter, with spikes on their surface similar to those seen on envelopes of herpes-type viruses. Significance of these bodies in vivo and in vitro tumor tissues is not known.

Virus-like particles in cystic mammary adenoma of a snow leopard.

Virus-like particles were observed in the giant cells of a mammary adenoma of a snow leopard kept in captivity. Particles that measured 115 to 125 nm in diameter budded from the lamella of endoplasmic reticulum and were studded on their inner surfaces with dense granules (approximately 12 nm) that gave them their unique ultrastructural morphology. Such particles were not observed extracellularly. Type B or type C particles were not seen in the tumor tissue.
