The Effects Of Para-Chlorophenylalanine On A Conditioned Emotional Response In Rats, Roy J. Hartmann
The Effects Of Para-Chlorophenylalanine On A Conditioned Emotional Response In Rats, Roy J. Hartmann
Theses & Dissertations
The initial intent of this study was to investigate p-CPA's actions on conditioned "anxiety" (CER) in rats in order to ascertain whether the derived effects were qualitatively similar to those previously reported for "conflict" behavior. Specifically, the goals of this study were to determine if p-CPA would reinstate lever-pressing behavior that had been suppressed by a series of tone-shock pairings. If a change in behavior did occur, would the reintroduction of serotonin, through the use of 5-HTP, return the behavior to pre-drug control levels.
Ultrastructure Of The Chorionic Villi In The Term Baboon (Papio Sp.) Placenta, Carol Ann Baker
Ultrastructure Of The Chorionic Villi In The Term Baboon (Papio Sp.) Placenta, Carol Ann Baker
Theses & Dissertations
The purpose of this paper is to describe the ultrastructure of the chorion frondosum of the baboon fetal placenta at or near term gestation. There is a void or, at best, only limited ultrastructural information in almost all fields of the biological sciences. The area of placentation is no exception. Since the ultimate goal of many scientific endeavors is the contribution to the vital field of human health, this investigator feels that much information can be gained through the utilization and study of the nonhuman primates in scientific research. The baboon (Papio sp.) has been shown to be quite similar …
