A comparative study of thin coatings of Au/Pd, Pt and Cr produced by magnetron sputtering for FE‐SEM
Publikováno v:
Journal of Microscopy. 189:79-89
Visualization of structural details of specimens in field emission scanning electron microscopy (FE-SEM) requires optimal conductivity. This paper reports on the differences in conductive layers of Au/Pd, Pt and Cr, with a thickness of 1.5–3.0 nm,

The degeneration process of lensfibres in a cataractous lens, described as the biochemical changes of a part of the lensproteins, can be characterised morphorogically as follows: Emulsification of a part of the lensfibre-mass and the development of o

Mersilene (polyester monofilament) seems to be suitable for penetrating keratoplasty because it is strong, shows no degradation by ultraviolet light, is insoluble, so that it can be left in situ, and offers the possibility of regulating postoperative
Study of the substructure of the Morgagni and Brunescens cataract with the TAO non-coating technique

Lens tissue from a Morgagni cataract was examined by SEM and TEM. For SEM, after prefixation with glutaraldehyde and postfixation with the tannic acid/arginine/OsO4 non-coating (TAO) technique, and for TEM, after prefixation with glutaraldehyde, post

A male patients (42 years) who had been treated for retinal detachment by the implantation of a silicone plombe into the sclera, returned to the clinic 8 years after implantation because of inflammation of the tissue and partial protrusion from the s

Cataract lenses from patients of advanced age were processed for SEM by standard pre-fixation followed by treatment by the Tannin-Arginine-Osmium-tetroxide (TAO) method and critical point drying, and for TEM by standard pre-fixation followed by vibra

Nylon and stainless steel sutures separately placed deeply into rabbit corneas by splitting the stroma for a few millimeters, without closing sutures, remained in the cornea for two, four and six weeks respectively. In contrast to the stainless steel

A new and simple technique for glaucoma filtering surgery is presented. It is based on the introduction of a stainless steel microspiral or gonioseton into a goniopuncture by way of an ab interno procedure, minimising surgical trauma to the filtratio

Secondary cataract material from three patients, collected with a glass cannula approx. 18, 24 and 30 months respectively after operation, was prepared for SEM examination. For the soft samples this was done by filtration through a millipore filter f

Non-coating fixation methods, in particular the tannic acid/arginine/osmium tetroxide procedure, are employed for a number of reasons on the guinea-pig organ of Corti hair cell stereocilia glycocalyx and the imprints of the stereocilia at the bottom
