In a combined lymphangioscopical and ultrastructural examination 7 months post telecobalt 60 irradiation with 60 Gy, the morphological and functional aspects of the inner laryngeal lymph capillaries were studied. The prominent feature of the morphological changes was the endothelial damage of the lymphatic capillaries including swelling, vacuolisation and(More)
The influence of two fixation buffers on the quantitative cytoarchitecture of the cochlear spiral ganglion in guinea pigs was evaluated morphometrically. After fixation with phosphate buffered 1.3% OsO4 granular spiral ganglion cells lost 45% of their average individual volume as compared to the volume after fixation with s-collidine buffered 1.3% OsO4.(More)

The proceedings of restitution after Streptomycineintoxication were examined on Guinea-pigs cristae ampullares. The animals were sacrificed 10, 14, 16 days after the tenth injection of Streptomycine (250 mg/kg and day). At this time no visible damage of the sensory cell's plasma could be seen, though at the same time the sensory hairs showed signs of(More)
The influences of various fixative-methods on the crista ampullaris of healthy guinea pigs have been studied. The following methods were used: 1. Vascular perfusion with 3% glutaraldehyde, postfixation with osmiumtetroxide (Millonig). 2. Vascular perfusion as under Nr. 1, prewash with Novocain and Liquemin. 3. Intraampullar fixation with 3% glutaraldehyde,(More)
The comparison of ultrastructural and ultrastructural-morphometric findings in spiral ganglion cells subsequent to broad noise with 105 dB SPL over a period of 40 min demonstrates that there are morphometric changes of the cytoarchitecture of granular ganglion cells even without evident ultrastructural changes. Morphometric analyses shows a significant(More)
