false glomerulus in renal biopsy specimen a possible pitfall under the Dissecting Microscope
Journal of Clinical Pathology, 2004Co-Authors: H HattoriAbstract:Renal biopsy is often invaluable for the diagnosis of glomerular disease. Needle biopsy samples of the renal tissue are usually divided up into separate samples for light microscopy, immunofluorescence, and electron microscopy, preferably under a Dissecting Microscope.1 This is a relatively easy task if a sufficient amount of the sample is obtained. However, if biopsy samples are small or turn out to be composed mostly of medulla, priority is usually given to light microscopy. In such circumstances, one may have to use a …

Dissecting Microscope versus magnifying loupes with transillumination in the preparation of follicular unit grafts a bilateral controlled study
Dermatologic Surgery, 1998Co-Authors: Robert M Bernstein, William R RassmanAbstract:background. The increasing importance that hair transplant surgeons are placing on maintaining the integrity of the naturally occurring follicular unit has generated great interest in finding the ideal method of graft dissection. objective. The present study attempts to compare two popular Dissecting techniques: the Dissecting Microscope, and magnifying loupes with transillumination, in the preparation of follicular unit grafts. methods. Donor strips from 41 patients were used in a prospective, bilateral controlled fashion to compare the two different Dissecting techniques. results. Microscopic dissection produced a 17% greater yield of hair as compared with magnifying loupes with transUlumination. conclusion. The results of this study show an increase in the yield of follicular unit grafts, as well as the total amount of hair harvested from the donor strip, when using the Dissecting Microscope as compared with magnifying loupes with transUlumination. This increase was observed when only the latter part of the Dissecting procedure was studied. When complete microscopic dissection is used, the advantage should be even more significant.

a multiaxis device for in focus manipulation of objects under a Dissecting Microscope
Journal of Microscopy, 2014Co-Authors: Heribert GrasAbstract:Summary An inexpensive specimen holder for objects under a Dissecting Microscope is described which allows arbitrary orientation and rotation of the object within the visual field and focal plane of the Microscope. Based on a spherical cap upon a magnet, this apparatus is easy to construct and permits single-handed manipulation of the specimen from some distance. Precise positioning is demonstrated for halteres of Drosophila under up to 120× magnification. Because of the restricted field of view and depth of focus of a Dissecting Microscope, it is often difficult to position tiny objects under study in varying orientation, especially if the specimen must simultaneously be dissected with forceps, microscissors or needles. The problem is solved most conveniently with a specimen holder based on a spherical cap which is held by a strong magnet on a steel ring. The specimen tilts vertically in any direction by up to 70° and—even in oblique orientation—rotates through 360° around the sphere's centre in the focal plane. By help of an interleaved plastic foil in a ring carrier, these movements can be controlled unimanually from outside the visual field.

Fundamentals of Scanning Electron Microscopy
Microvascular Corrosion Casting in Scanning Electron Microscopy, 1992Co-Authors: S. H. Aharinejad, Alois LametschwandtnerAbstract:Although vascular corrosion casts can be studied light microscopically by the Dissecting Microscope the fine details which today’s casting media replicate can be resolved by the scanning electron Microscope (SEM) only. The high depth of focus, the high resolution together with the possibility of manipulating the specimen under the electron beam have made the scanning electron Microscope a valuable tool for a thorough study of vascular corrosion casts.
