Prostaglandin Synthesis In The Feline Adrenal Cortex, Suzanne Gale Laychock

Theses and Dissertations

Studies were carried out on the feline adrenal gland to ascertain the role of prostaglandins in the mechanism of action of ACTH. Using tritiated arachidonic acid as a prostaglandin (PG) precursor , it was demonstrated by column and thin layer chromatography techniques that isolated trypsinized adrenocortical cells possess an active PG synthetase capable of synthesizing radiolabeled PGE, PGF, and PGA/B-like substances. Concentrations of ACTH (125 - 250 _μU) which stimulate steroidogenesis enhanced the conversion of radiolabeled arachidonic acid to PGE, PGF and the PGA/B products extracted from cortical cells and incubation media.

PG biosynthesis by isolated cortical cells was …

The Relationship Of The Sixteen Personality Factor Questionnaire Inventory To Clients Of A Methadone Maintenance Program, Margaret Ann Neale

Theses and Dissertations

An original study was undertaken to examine the relationship of clients of Project Jump Street, Inc., a methadone maintenance program, to changes in personality factors as measured by R.B. Cattell's Sixteen Personality Factor Inventory, to compare the national norms of drug addicts/methadone users to the result of the 16 PF of clients of Project Jump Street, Inc., and to determine if significant differences appear among treatment phase I, phase II, and phase III.

Twenty-one clients of the program, seven subjects in each of phases I, II, and III, were given the 16 PF by their counselors between September 10 and …

Synthesis And Evaluation Of Some Arylalkenyl And Arylepoxyalkyl Hydrogen Succinates And Hydrogen Glutarates As Inhibitors Of Rat Liver Β-Hydroxy-Β-Methylglutaryl Coenzyme A Reductase, Paul Emil Marecki

Theses and Dissertations

Atherosclerotic disease is an almost universal phenomenon and increases in severity and frequency with increasing age. Atherosclerosis may contribute to several disorders including bursting of an artery, blockage of an artery, or induction of arterial clotting. The culmination of these diseases is usually premature since at the time of death the unaffected organs are in reasonably satisfactory condition and could have operated for several more years. Among the many factors which act in concert to produce the disease, serum cholesterol levels play a central role. It has been suggested that the lowering of cholesterol levels will provide an effective means …

Inhibition Of Cell Division, Protein Synthesis And Nucleic Acid Synthesis In Escherichia Coli W By Tetracycline Antibiotics, George Henry Miller

Theses and Dissertations

Tetracyclines, originally isolated in the late 1940's and early 1950's from the mycelium of Streptomyces, have achieved major importance as therapeutic and prophylactic agents against a wide range of infections in human and veterinary medicine. They have also achieved great importance in agriculture where they are widely used to promote weight gain in livestock. Commercial production, during 1958 in the United States alone was 120 tons with a value of approximately $1 million per ton.

The clinical importance of these compounds has stimulated efforts to define their mode of action as inhibitors of bacterial reproduction. Antibiotics having as many functional …
