Antibradykinin Evaluation Of Cryogenine And Selected Other Agents, Ralph William Trottier Jr.

University of the Pacific Theses and Dissertations

One intent of this study was to detect and to define any antibradykinin capacity that cryogenine may have using both in vivo and in vitro pharmacological models. The activity of cryogenine in these tests was compared to a variety of clinically-proven anti-inflammatory compounds as well as to other agents known to possess anti-inflammatory activity in certain experimentally-induced inflammations. Cryogenine is an unusual anti-inflammatory agent since it is an alkaloid - all of the commonly used anti-inflammatories (aspirin, phenylbutazone, indomethacin, etc.) are organic acids.

A Pharmacologic Investigation Of The Antiinflammatory Activity Of Cryogenine, Donald Saadia Kosersky

University of the Pacific Theses and Dissertations

This study was conducted in an attempt to define the anti inflammatory efficacy of cryogenine, the major alkaloid of Heimia salicifolia Link and Otto. The anti inflammatory effects produced by cryogenine, phenylbutazone, indomethacin, mefenamic acid, paramethasone, hydrocortisone and 6-mercaptopurine were compared considering the sequential changes in various motameters during the course of adjuvant-induced polyarthritis in rats. Polyarthritis was induced by the subplantar injection of a suspension of heat-killed Mycobacterium butyricus in mineral oil into the right hind paw of Sprague-Dawley rats. The manifestations of the diseases were monitored in terms of hind paw swelling, subjective appearance of secondary lesions, impairment …

In Vitro Resorption Characteristics Of Selected Diuretic Compounds By Thedesaga Resomat, Donald Gene Floriddia

University of the Pacific Theses and Dissertations

An in vitro method was tested whereby the processes of dissolution and distribution of active ingredient into a lipoid solvent were combined in one model and evaluated.

The objectives of this research project were: (1) to evaluate the efficacy of the in vitro model known as the Desaga Resomat, in the testing of gastrointestinal absorption; (2) to apply the procedure and instrument to a group of therapeutically important products in determining their absorption characteristics; (3) to graphically illustrate the absorption profile of a specific drug as per cent absorbed vs. time, simulating in vivo absorption; (4) to compare the profile …

The Effects Of Indomethacin On A Strain Of Fibroblasts Cultivated In Vitro, John Thomas Mccloskey

University of the Pacific Theses and Dissertations

Man has always searched for greater understanding of himself and his environment. As a result, much scientific investigation has been directed towards the understanding of the life process. In recent years, such scientific inquiry has become increasingly focused on the fundamental biochemical events taking place at the cellular, subcellular, and molecular levels. In the course of investigation into the nature of living things, research has often necessitated the development of new techniques and investigational tools to serve as experimental systems. Very often such new methods have made possible the discovery of previously unknown processes. One very interesting and useful investigational …

The Development Of An Oral Inhalation Dosage Form Antinauseant, Kit Michael Mills

University of the Pacific Theses and Dissertations

It would seem appropriate that studies be conducted on the development of an oral inhalation dosage form antinauseant. The present project will consist of developing and testing a series of aerosol formulations to determine their feasibility in antinauseant therapy. In vitro pressure, valve release, spray pattern, particle size, and aging studies will be performed. The present work will also include an in vivo evaluation of promising formulations.

Observations Related To The Mechanisms Of Tetracycline-Induced Lipid Accumulation In A Strain Of Mouse Fibroblasts Cultivated In Vitro, Dale William James

University of the Pacific Theses and Dissertations

Intravenous administration of tetracycline has been known to result in fatty degeneration of the liver. This study was undertaken in order to elucidate some of the actions of tetracycline on mammalian cells in culture and to attempt to relate these findings to the clinical condition of fatty degeneration of the liver mentioned above.

It is suggested that lipid accumulation occurring after tetracycline administration is possible the result of a decrease in B-lipoprotein synthesis and enzyme inhibition. These factors could result from the high blood levels of tetracycline seen after large and rapid intravenous injections of the drugs into normal patients …
