Morphological Analysis Of Microvessels Using High Voltage Electron Microscopy (Hvem), Ibm Personal Computer And 3-D Reconstruction Software, Wieslaw Slawomir Krajewski

Theses

The mesenteric arterioles (outer diameter < 100 µ) from a normotensive and a hypertensive dog were perfused in situ, excised, post-fixed and embedded in Spurr medium block. Thick serial cross sections (0.5 µ) of the vessels were obtained from hand formed mesas and placed on Formvar coated slot grids.

The cross sections were subjected to High Voltage Electron Microscopy (HVEM) and five or more electronmicrographs were taken to cover the individual cross sections. The prints of electronmicrographs were linearly enlarged (3X) and made into photomontages of sections. The membrane contours in the montages were traced on transparent overlays, producing polygons which in turn were traced on GTCO digitizing pad. All polygons were labeled, color coded and stored in IBM PC's filing system. The vessels were reconstructed from up to 100 whole cross sections and subjected to cell compartmentalvolume analysis. The reconstructed images can be …

Technology Transfer Between Developed And Developing Countries, Tenny Oghogho Ogbomo

Theses

The problems arising from technology transfer, in general, are not new. The problems of the East-West technology transfer, for example, are based on the risk that such transfers will enhance the military capability, or at least the military potential, of the trading partner. In the case of United States trade with the Soviet Union, it can be said that any accretion in the Soviet military capacity weighs against the United States in an overall world-wide balance of power. The restrictions and/or prohibition of such transfer of technology are problems themselves.

The North-South technology transfer, in other words, the technology transfer …

Criteria For Selecting Materials Suitable For Application To Modified Atmosphere Packaging Of Fish, Yvonne Allen

Theses

The process of preservation is an important step in stabilizing perishable items in order for them to withstand distribution, handling, and storage. Preservation can be achieved by several methods, but the method of concern in this paper is that of modified atmosphere storage which is reported to extend the shelf-lives of perishable products. Studies on modified atmosphere storage have emphasized the preservating action of carbon dioxide (CO2) in reducing (1) the extent of microbial spoilage, and (2) the tissue pH of the products so stored in comparison to those stored aerobically. Low tissue pH creates unfavourable environment which negatively influences …

Investigations Into Rates And Mechanisms Of Mercury Depuration In The Killifish, Fundulus Heteroclitus, Joanne A. Korpanty

Theses

Metallothionein (MT) and glutathione (GSH) have been shown in mammalian research to play a role in the sequestration and depuration of mercury. The sulfhydryl groups on both these peptides have a strong affinity for mercury, MT for Hg²⁺ and GSH for CH₃Hg⁺. In this study, killifish (Fundulus heteroclitus) were force-fed one piece of squid laced with labelled mercuric nitrate to give a final food concentration of 20 ppm ²⁰³Hg²⁺ and 0.03 -0.05 µg g-1 Hg²⁺ total dose. Most of the mercury, 84.1 ± 12.1% (mean ± standard deviation), is depurated within the …

Effects Of Two Chelating Drugs On Trace Element Metabolism In The Rat, Thomas J. Solecki

Theses

Numerous drugs have structures which suggest that they and/or their metabolites are likely to be chelating agents and therefore might affect trace element metabolism. For some drugs, their therapeutic activity or side effects may be due to this chelating potential. Ethambutol, used in the treatment of tuberculosis, is an example. There is also evidence that other drugs, such as alpha-methyldopa, may possess this potential; although its primary therapeutic action occurs via mechanisms other than chelation. The objective of this thesis was to determine the effects of ethambutol and alpha-methyldopa on tissue metal concentrations and balance of four essential trace metals: …
