Cocaine And Timing: Drug Effects Under A Mixed Fixed-Interval Extinction Schedule, Vincent O. Hodge
Cocaine And Timing: Drug Effects Under A Mixed Fixed-Interval Extinction Schedule, Vincent O. Hodge
Masters Theses
The effects of cocaine hydrochloride (3.2-56.2 mg/kg) were determined in rats performing under a mixed fixed-interval 60-seconds extinction 120-seconds schedule of food delivery. Responses were recorded in successive 5-second bins. With the exception of the highest dose (56.2 mg/kg), cocaine did not significantly affect rate of responding under the fixed-interval component or extinction component, or the time of peak responding under the extinction component. The highest dose significantly reduced response rates and shifted the time of peak responding leftward to quicker and earlier moments. Results are discussed in terms of possible rate- and time-dependent effects of stimulant drugs.
Effects Of Phenobarbital In Combination With Phenytoin Or Valproic Acid On The Delayed-Matching-To-Sample Performance Of Pigeons, Catherine Ann Karas
Effects Of Phenobarbital In Combination With Phenytoin Or Valproic Acid On The Delayed-Matching-To-Sample Performance Of Pigeons, Catherine Ann Karas
Masters Theses
The present study examined the effects of phenobarbital (S, 10,20, and 40 mg/kg), phenytoin (2.5, 5, 7.5, and 15 mg/kg), and valproic acid (40, 60, 80, and 120 mg/kg), and those of phenobarbital (10 and 20 mg/kg) in combination with phenytoin (2.5,5, and 7.5 mg/kg) or valproic acid (40, 60, and 80 mg/kg), on the delayed-matching-to-sample performance of pigeons. In general, high doses of each individual drug reduced accuracy. Drug combinations also reduced accuracy relative to control values. Reductions in accuracy produced by drug combinations were very similar in magnitude to those predicted by a response-addition model of drug interaction.
A Biochemical Study Of Gossypol And Lactate Dehydrogenase X Binary Interactions, Patricia Brown Ravenell
A Biochemical Study Of Gossypol And Lactate Dehydrogenase X Binary Interactions, Patricia Brown Ravenell
Theses and Dissertations in Biomedical Sciences
The goal of this project was to study the mechanism of action of gossypol through its (a) binary interaction with native and trypsin digested lactate dehydrogenase-X (LD-X), a sperm-specific isozyme, and (b) its binding in vitro in primary cultures of spermatogenic cells. Mouse LD-X was cleaved with trypsin before and after treatment with gossypol. This was followed by high performance chromatography (HPLC) separation of the LD-X tryptic peptide fragments to observed alterations in separation patterns as indicators of intramolecular disturbance in the enzyme molecule. Definite alterations in peptide fragment peaks were observed in the presence of gossypol and suggest conformational …

Evidence For The Elevation Of Serum Carcinoembryonic Antigen And Tumor-Associated Glycoprotein-72 Levels In Patients Administered Interferons, John Greiner, Fiorella Guadagni, David Goldstein, Ernest Borden, Roy Ritts, Patricia Witt, Albert Lobuglio, Mansoor Saleh, Jeffrey Schlom
Haematology and Oncology, East Africa
Sera were collected from 111 patients diagnosed with adenocarcinoma or nonadenocarcinoma malignancies who received different schedules of interferon (IFN)-γ or IFN-βser alone or in combination. Serum carcinoembryonic antigen (CEA) and tumor-associated glycoprotein-72 (TAG-72) antigen levels were measured to determine whether interferon could enhance the tumor shedding and, thereby, the serum level of either tumor antigen. Less than 10% of the sera samples from patients diagnosed with nonadenocarcinoma malignancies (e.g., hairy cell leukemia, melanoma) had positive titers of TAG-72 or CEA, and interferon neither increased nor resulted in the appearance of either tumor antigen in those sera. In contrast, 59.2% and …

Pharmacokinetics And Effects On Blood Chemistry Of Cyclosporine In Human Infants And Kid Goats, Floyd A. Beierle
Pharmacokinetics And Effects On Blood Chemistry Of Cyclosporine In Human Infants And Kid Goats, Floyd A. Beierle
Loma Linda University Electronic Theses, Dissertations & Projects
Kid goats (newborn) have been used in transplantation protocols to study the techniques and problems of infant human cardiac transplantation. Immunosuppression has been by cyclosporine in both species. However, the pharmacokinetics of cyclosporine (CSA) in both the kid goat and human infant were unknown. Therefore, the pharmacokinetics of CSA were investigated. A single dose study and a long term chronic administration study were undertaken in the goat. Six Nubian goats, ages 60-90 days, were given a single IV dose of CSA, 0.25 mg/kg, over a 10 minute period and 72 hr later an oral cyclosporine dose of 20 mg/kg. The …
Molecular Mechanisms Of Physalia Physalis Venom Modulation Of Cardiac And Vascular Functions, Eva Luo
Molecular Mechanisms Of Physalia Physalis Venom Modulation Of Cardiac And Vascular Functions, Eva Luo
Loma Linda University Electronic Theses, Dissertations & Projects
Portuguese man-of-war (Physalia physalis)venom has profound effects on the cardiovascular system of man and animals. The venom produces vascular relaxation in norepinephrine precontracted, intact rabbit femoral arterial rings by stimulating vasodilatory prostaglandin synthesis in the endothelium. This action does not depend on endotheliumderived relaxing factor (EDRF). P. physalis venom produces a vascular constriction on KC1 depolarized, intact rings. This is completely inhibited by dibenzyline and yohimbine. Increased membrane permeability to calcium may be involved in direct vascular smooth muscle stimulation. The venom has a positive inotropic effect on rat atrial preparations, which is intensified by increased extracellular calcium concentration. …
