2The Prostatic Epithelial Cell in Dysplasia: an Ultrastructural Perspective

CR DEVRIES,JE MCNEAL,K BENSCH

The histologic features of prostatic duct‐acinar dysplasia have been difficult to analyze ultrastructurally, because of the difficulty in properly selecting and processing such small, randomly situated grossly invisible lesions. We have succeeded in identifying dysplastic foci by examination of the cut surfaces of tissue slices under low magnification. Dsyplasia foci were excised from the slices and were compared to adjacent normal tissue by both light and electron microscopy. By electron microscopy (EM), normal secretory cells were filled with myriad tiny clear vacuoles, which were markedly diminished to absent in the cytoplasm of dysplastic cells. Both apocrine and eccrine secretion characterized normal epithelium and were diminished in dysplasia. EM showed striking features of nuclear abnormality more prominently than light microscopy, and qualitative basement membrane abnormalities were revealed. By EM analysis, dysplastic epithelium resembled that of invasive carcinoma more than normal epithelial cells.

3Endoscopic Urethroplasty: an Improved Technique.

CR DEVRIES,RU ANDERSON

Endoscopic urethroplasty is an excellent alternative to open repair of the traumatically disrupted posterior urethra. It offers the advantage of limiting surgical trauma to an already scarred urethra and pelvic floor. Our technique also allows fluoroscopic guidance of the recanalization procedure to align the new urethral channel precisely with minimum disruption of the nerves and muscles of the periurethral tissue and pelvic floor. It obviates the need for a second surgeon viewing the urethra from above as has been required in previously described techniques. This procedure allows for maximal preservation of residual post-traumatic continence and erectile function because it minimizes blind passage of instruments.

4Acute Toxicity of Lead Particulates on Pulmonary Alveolar Macrophages - Ultrastructural and Microanalytical Studies

C R deVries,P Ingram,S R Walker,R W Linton,W F Gutknecht,J D Shelburne

Although it is well established that respiratory uptake of lead-containing particles plays a substantial role in the epidemiology of plumbism, relatively little is known about the role of the pulmonary alveolar macrophage in lead poisoning. An in vitro system was designed to investigate the effects of lead oxide particles of respirable size on the rabbit alveolar macrophage. The studies were concerned with the intracellular solubility of PbO and Pb3O4 and changes in fine structure attributable to lead toxicity. The distribution of phagocytosed lead and its intracellular reprecipitation complexes was established by electron microprobe analysis and secondary ion mass spectroscopy in conjunction with transmission electron microscopy, scanning electron microscopy, scanning transmission electron microscopy, and backscatter imaging. It was found that Pb3O4, PbO and PbO-coated particles were ingested by the rabbit alveolar macrophages and that each of these lead oxide compounds produced similar damage to the fine structure of the cell. Swelling of the mitochondria, nuclear membrane, and endoplasmic reticulum was common, as well as were characteristic reprecipitation complexes of lead, phosphorous, and calcium within the nuclear heterochromatin and cytoplasm of the cell. The precipitation complexes were not seen in cells incubated with the particles if phagocytosis was blocked by 0.22-microns, membrane filters. It was concluded that phagocytosis of these lead oxide particles was necessary to produce the cytopathic changes. It is suggested that solubilization of lead from the ingested particles in phagosomes of macrophages results in the liberation of intracellular lead with the resultant formation of reprecipitation complexes.

6Ion Microanalysis of Cells.

R W Linton,S R Walker,C R DeVries,P Ingram,J D Shelburne

The application of ion microanalysis (IMA) to the chemical characterization of freeze-fixed, freeze-dried cells is reviewed. Particular emphasis is given to pathological studies involving the determination of the chemical composition of isolated cells (e.g. rabbit alveolar macrophages--RAMs) exposed in vitro to toxic species (e.g. Pb3O4 particles). Ion microscopic results indicated that lead from Pb3O4 migrated into the RAMs and subsequently formed phosphorous-containing compounds. Quantitative comparisons of the relative concentrations of physiologic elements in Pb3O4-treated versus control RAMs also were made using ion microanalytical techniques. The Pb3O4 results illustrate that the three-dimensional analysis capabilities of the IMA may be exploited for the in situ observation of the penetration of xenobiotic agents into cell interiors and their subsequent intracellular chemistry. The potential advantages of ion microanalysis for the characterization of cells include high elemental sensitivity (including low atomic number elements and diffusible ions), broad elemental coverage, three dimensional analysis, and isotopic information. The major limitations include non-idealities of the ion sputtering process, the constraints on the lateral resolution available to identify subcellular features, and the difficulties inherent in the determination of absolute elemental concentrations.
