The inadvertent injection of sodium hyaluronate (Healon) just anterior to Descemet's membrane during an extracapsular cataract extraction resulted in a corneal opacity. No extraordinary measures were taken to remove this substance. The opacity resolved over five months, with a final visual acuity of 20/25 and a reduction in specular microscopic cell density(More)
We describe a case of primary amebic meningoencephalitis due to Naegleria fowleri. This is the first reported case, to our knowledge, in Missouri. Emphasis is placed on the morphologic identification of degenerating amebas in a cytospin preparation of cerebrospinal fluid using Wright's stain during the rapidly progressive meningoencephalitic stage.
It is now firmly established that disaccharidases are an intrinsic part of the mammalian intestinal (1) and renal (2) brush border. Isolated brush borders of hamster and rabbit intestine (3-6) are studded with knobs (65 A in diameter) or doughnut-shaped particles (45-110 A in diameter) respectively, when viewed as negatively stained preparations . Isolated(More)
In previous papers’ were reported the results of studies on the influence of the thyroid and kidney on post mortem autolysis of liver tissue at body temperature. These experiments were carried on by different methods; (1) by ascertaining the proportion of nitrogen which existed in different forms, (a) coagulable, (b) non-coagulable but precipitable by zinc(More)
