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 …

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 …

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.

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 …

A Study Of Several Factors Incident To The Absorption Of Choline From The Small Intestine Of The Albino Rat, Ralph E. Purdy

University of the Pacific Theses and Dissertations

The substance choline, one of the quaternary nitrogen bases, has been the subject of a number of reviews and investigations. It has been described as a cholinergic agent, an inotropic agent, a vitamin, and perhaps in other ways. In spite of the interest shown in its action and uses, there is as yet very little information available as to the mechanism by which it is absorbed by the intestinal mucosa.

The studies referred to thus far leave the field open for additional investigation. No mention was found in the literature of studies on selective areas of absorption of choline in …
