Pentylenetetrazol-Induced Seizures In Pigeons And The Effects Of Ethosuximide Thereon, James J. Jakubow
Pentylenetetrazol-Induced Seizures In Pigeons And The Effects Of Ethosuximide Thereon, James J. Jakubow
Masters Theses
Previous research has shown that ethosuximide in high enough doses will disrupt operant responding in pigeons. Whether or not these same doses will protect against seizure activity in this species has not been previously tested.
To test this question a system for scoring pentylenetetrazol-induced seizures in pigeons was developed and the effects of ethosuximide on such seizures were evaluated. In Experiment 1 pentylenetetrazol at 15, 27 and 47 mg/kg reliably induced seizures. In Experiment 2 non-behaviorally active and behaviorally active doses of ethosuximide were tested for their seizure controlling effectiveness.
Doses of 20, 40, 80, 160 and 320 mg/kg ethosuximide …
Determination Of Antibody Levels In Periapical Lesions Against Sixteen Oral Microorganisms By The Elisa Technique, Sammee Lee Jones
Determination Of Antibody Levels In Periapical Lesions Against Sixteen Oral Microorganisms By The Elisa Technique, Sammee Lee Jones
Loma Linda University Electronic Theses, Dissertations & Projects
The root canal system, which includes the periapical region of the tooth, may become infected by several types of microorganisms which are normally associated with these tissues. A bacteria-specific antibody response may occur at the local level, where various classes of immunoglobulins have been found and reported in the literature. The purpose of this study was to quantitatively measure locally produced immunoglobulin' levels in periapical lesion abscess materials and to determine the specific reactivity of these antibodies to several microorganisms which are normal flora, as well as being previously associated with the development and pathogenesis of endodontic infections. Periapical lesions …
The Role Of Homeostatic Imbalance In The Reported Immunomodulation Of T-2 Toxin, Michael Jay Taylor
The Role Of Homeostatic Imbalance In The Reported Immunomodulation Of T-2 Toxin, Michael Jay Taylor
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
T-2 toxin (T-2), produced by the genus Fusarium, is a cytotoxic trichothecene mycotoxin, a feed contaminant, and has been shown to be immunomodulatory. It is suspected that T-2-associated immunomodulation is mediated partly through the hypothalamic-pituitary-adrenal axis. The presence of endotoxin, a bacterial product capable of activating the hypothalamic-pituitary-adrenal axis as well as the levels of several hormones, also associated with activation of the hypothalamic-pituitary-adrenal axis, were determined in both vehicle- and toxin-treated animals. Endotoxemia was evident twenty-four hours after a single oral exposure to T-2. Blood levels of adrenocorticotropic hormone and corticosterone, parameters of the stress response, also increased …
A Biomechanical Analysis Of The Effect Wear Patterns Of Running Shoes Have On Kinematic Variables Of The Lower Extremities, Audrey E. Randall
A Biomechanical Analysis Of The Effect Wear Patterns Of Running Shoes Have On Kinematic Variables Of The Lower Extremities, Audrey E. Randall
Masters Theses
The purpose of the study was to investigate the relationship between wear patterns of running shoes and selected kinematic variables of the lower extremities. Statistical analyses were completed by using a case study design for two male subjects. Subjects were filmed for ten strides on six different sessions over a three-month period. A two-way ANOVA design, with repeated measures, evaluated the dependent variables: (a) footstrike, (b) midstance and (c) toeoff phases. The degree of change was determined by digitizing ten points on the body. A University of California, Los Angeles, BMDP2V statistical package was used to determine differences between means. …

The Stress Buffering Effects Of Positive Life Events And Personality (Hardiness) In Undergraduates With Dental Anxiety, Janette Louise Seville
The Stress Buffering Effects Of Positive Life Events And Personality (Hardiness) In Undergraduates With Dental Anxiety, Janette Louise Seville
University of the Pacific Theses and Dissertations
Previous studies have independently identified positive life events and the hardy personality as variables that reduce the influence of life stress on physical or paychological disturbance. The present study investigates the possible stress buffering effects of hardiness and positive events. Seventy-five undergraduates, identified as having dental anxiety, were randomly assigned to one of five film groups. Groups viewed either a positive film, a negative film, both films (in one of two sequences), or no film. Dependent measures of dental anxiety. positive affect, negative affect, and heart rate were observed. Multiple tests of a priori hypotheses yielded partial support for the …
