Intimal thickening in human arteries is considered as a site of predilection for atherosclerosis. The placement of a flexible, physically nonconstrictive, silicone cuff around the rabbit carotid artery induced a neointima composed of smooth muscle cells (SMCs) within 14 days. To investigate possible alterations of the endothelial cells (ECs) during neointima formation, their morphology was exam...

The mammalian pharynx is a hollow muscular tube that participates in ingestion and respiration, and its size, shape, and stiffness can be altered by contraction of skeletal muscles that lie inside or outside of its walls. MRI was used to determine the interaction between pharyngeal pressure and selective stimulation of extrinsic tongue muscles on the shape of the rat nasopharynx. Pressure (-9, ...

BACKGROUND During sedation for upper gastrointestinal endoscopy, oxygen delivery via a nasal cannula is often necessary. However, the influences of the oxygen delivery route and breathing pattern on the F(IO2) have not been thoroughly investigated. The aim of this simulation study was to investigate the difference in the F(IO2) with a pharyngeal cannula versus nasal cannula during high- or low-...

Sir,—Your issue for November 1971 has just come to hand. The report by D. G. Moyes and M. A. Rogers (Brit. J. Anaesth., 43, 1099) emphasizes a real hazard in areas where ascaris is endemic, and is a salutary reminder that intubation of the trachea does not necessarily guarantee a clear airway. Obstruction from this cause has in fact been reported previously (Boulton and Cole, 1967). We recently...
