INFORMATION TO USERS This manuscript has been reproduced from the microfilm master. UMI films the text directly from the original or copy submitted. Thus, some thesis and dissertation copies are in typewriter face, while others may be from any type of computer printer. The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely affect reproduction. In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion. Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, beginning at the upper left-hand corner and continuing from left to right in equal sections with small overlaps. Each original is also photographed in one exposure and is included in reduced form at the back of the book. Photographs included in the original manuscript have been reproduced xerographically in this copy. Higher quality 6" x 9" black and white photographic prints are available for any photographs or illustrations appearing in this copy for an additional charge. Contact UMI directly to order.

Brueggemeier, Ph.D. College of Pharmacy To My Parents ii ACKNOWLEDGEMENTS I wish to express my sincere thanks to: My adviser, Dr. Dennis R. Feller, for his guidance, patience, and support throughout my graduate studies. His steady concern, friendship and encouragement make me feel as if I were not far away from home. The members of my dissertation committee: Dr. Lane J. Wallace, Dr. Allan M. Burkman and Dr. Robert W. Brueggemeier, for their valuable suggestions and comments. Dr. P.E. Kolattukudy, Julie Li, and Leena Hiremath from Biotechnology Center for their willing help and instructions on the molecular works. John Mitchell and Erin Hooksin for their assistance on Electron microscopic studies. My senior friends, Tim Esbenshade and Tom Kocarek, for their instructions and guidance in the hepatocyte culture system. My American, Korean, Egyptian, Indian, Venezualian and Chinese friends, in the Division of Pharmacology, whom make the fifth floor of Parks Hall a very enjoyable and memorable place, and whom open my world to other cultures. My Thai friends, Suparp, Vimon, Suchada, Chawewan, Sirinart, Rutaiwan, Precha, Wirot, Kasem, Pitsanu, Panida,..., for their worthwhile amity. Their presence make O.S. U. as well as Neil Hall an unforgettable place of mine. My room-mate and my close neighbor, Kulaya and Tidawadee, for their inestimable help, support and understanding. Their assistance in and out the apartment made it possible for me to devote all my time in writing this dissertation. My parents and my sister. I thank you for your sincere confidence in me and for your eternal support and encouragement throughout my studies. The Thai Ministry of Public Health, Department of Medical Sciences for partial stipend support. Finally, I would like to thank the Ohio State University and the United States of America for giving me an opportunity to pursue the Ph.D. degree. The financial support and the education which I received from here will always be appreciated. VITA October 27, 1960 .....................................................
