Diagnostic Implications of Percutaneous Atherectomy: Angioscopic, Histologic, and Cell Culture Study
In this study we report on percutaneous atherectomy, not only as a therapeutic modality, but also as a technique with diagnostic implications. The adjunctive use of angioscopy allows for the selective “biopsy”...

Licht- und elektronenmikroskopische Untersuchungen zur Entwicklung der Reissnerschen Membran im Ductus cochlearis von Meerschweinchenfeten
Differentiation of the Reissner's membrane (membrana vestibularis) is described in precisely dated guinea pig fetuses. In newborn and adult animals, the Reissner's membrane consists of two layers of flat cells...

The distribution of vasopressin-, oxytocin-, and neurophysin-producing neurons in the guinea pig brain
The location, cytology and projections of vasopressin-, oxytocin-, and neurophysin-producing neurons in the guinea pig were investigated using specific antisera against vasopressin, oxytocin or neurophysin in ...

Licht- und elektronenmikroskopische Untersuchungen des großen Epithelwulstes und seiner Beziehungen zu der sich entwickelnden Membrana tectoria im Ductus cochlearis von Meerschweinchenfeten
In early stages of fetal development (36th day, 3rd turn) the thickening of the epithelium at the basal side of the cochlear duct forms two ridges. Later in fetal development the laterally situated lesser epit...

Distribution of Vasopressin, Oxytocin, Neurophysin, Somatostatin, and Luteinizing Hormone Releasing Hormone-Producing Neurons
The use of immunohistochemical techniques has confirmed the presence of neurohypophyseal and adenohypophysiotropic hormones within axons and axon terminals of the median eminence (see ZIMMERMAN, 1976). The mag...

Die sphärischen Lipidkörper im Epithel des Plexus chorioideus beim Kaninchen
The epithelial cells of the choroid plexus in adult rabbits contain large spherical bodies (diameter up to 5 μ) of high electron density, which (by means of histochemistry) are shown to be lipids. Around their...
