Vital Apical Cortical Marginal Ostectomy, Elbert W. Clark

Loma Linda University Electronic Theses, Dissertations & Projects

The dentition has been suspect as an unfavorable influence in the healing potential of the jaws. Today, many surgical procedures are based on the supposition that teeth should be avoided, endodontically treated, or removed from the sphere of tissue infliction. On the other hand, and abundant blood supply and osteogenic capability have been recognized as favorable factors in repair.

An extra oral removal of an osteoid osteoma from the body of the mandible of a thirty-year-old female resulted in vital apicoectomies of her molar teeth as well as the removal of the medullary blood supply. An uneventful course of healing …

A Study Of The Differences In Responses Of Students And Alumni Of Two Types Of Nurse-Education Programs, To Questions Regarding Communication With Dying Patients, R. Cherie Mcclure

Loma Linda University Electronic Theses, Dissertations & Projects

The study concerned a comparison of responses made by students and alumni from two types of nurse-education programs, to questions regarding communications with dying patients. This was for the purpose of answering two questions: Are students of nursing given adequate preparation for coping with the psychological needs of dying patients? Are there significant differences in the way nurses from baccalaureate and associate degree programs cope with these needs? In an effort to obtain answers to these questions, a ten-part situational questionnaire was developed. It was assumed that some clue to a subject's ability to cope effectively in emotionally stressful situations …

The Relationship Between The Lingual Surface Of The Maxillary Central Incisor And The Eminence Of The Mandibular Fossae, Robert A. Huffer

Loma Linda University Electronic Theses, Dissertations & Projects

Gnathologists have suggested that in order to prevent excessive wear on posterior teeth, alveolar bone loss due to traumatic occlusion, and temporomandibular Joint (TMJ) disturbances, the mandibular incisors should disclude the posterior teeth by moving along the lingual surfaces of the maxillary incisors as the condyles move down the articular eminence in protrusion. It is suggested that in order for this to occur, the lingual surface of the maxillary incisors should be steeper than the eminence.

A cephalometric technique was developed to accurately determine the anatomical form of the articular eminence. A regular orthodontic tracing of the head was done …

An Electromyographic Comparison Of Muscle Action Potentials Of Listeners Presented Time-Compressed And Normal Speech Stimuli, Barbara S. Moon

Dissertations and Theses

Speech compression is a method of electromyographically reducing the speech signal, resulting in a decrease in the time required for presentation of a message by increasing the number of words per minute. Research in the area of speech compression has to this time been focused on determining the listener response by means of comprehension testing. While comprehension testing uncovers the individual's ability to resolve, organize, and recall a message at accelerated rates, it gives no information about the listener's psychophysical response to compression. Does the individual find listening to compression to be tension-provoking or stressful? Or can a listener accommodate …

Selective Inhibition Of Intestinal Amino Acid Transport By Three Heavy Metals, Verney Lee Sallee

Biomedical Sciences ETDs

Intestinal absorption of neutral amino acids, an active transport process, selects certain amino acids for transfer on the basis of their chemical structure. However, within the group of transported neutral amino acids, selectivity into secondary groups is not readily apparent, and only a relative variation of transport rate for each amino acid has been noted. A popular hypothesis, consistent with previously reported experimental observations, holds that intestinal transport of neutral amino acids occurs through mediation of one transport system with one effective binding site. In the kidney, however, heavy metals have been shown to produce a selective arninoaciduria of primarily …

Donation Of Organs For Transplantation: An Investigation Of Attitudes And Behavior, Courtney Weldon Goodmonson

Dissertations and Theses

While technological advances in immunology and surgery have permitted rapid increases in the number of homotransplantations now performed, little is known about layman’s attitudes toward donation of organs. Implicit in such progress has been the medical field's assumption that enough donor organs will be forthcoming to meet the increasing demand. In order to research this area a dual emphasis on practical and theoretical issues was employed. The purpose of the present study then, was to investigate this medical assumption by sampling the attitudes and behavior of college students toward donation of organs for transplant purposes, and at the same time, …

The Development Of Electrophysiological Techniques Allowing "In Situ" Measurement Of Electrical Changes Within Smooth Muscle Cells Of Mesenteric Micro-Vessels, William J. Willems

Master's Essays (1922 - )

The primary objective or this study is essentially to acquire further knowledge of the factors involved in the nervous and humoral control of vascular smooth muscle tone. The relative importance of the nervous and endogenous vasotropic humoral control or vasomotor tone under normal conditions as well as under conditions or hypotension can be evaluated, at least in part, by observing the electrical activity occurring in single vascular smooth muscle cells of the mesenteric microcirculation. This thesis describes: 1) the development of electrophysiological methods for the measurement of such activity in ''in situ" micro-vessels with circulation and innervation intact, and 2) …

Induced Early Closure Of The Spheno-Occipital Synchondrosis In The Guinea Pig, Arthur A. Ewert

Loma Linda University Electronic Theses, Dissertations & Projects

This study was designed to explore the significance of the spheno-occipital synchondrosis in cranial base and craniofacial development.

Premature fusion of the spheno-occipital synchondrosis in the guinea pig was induced by placing a wire staple in the cranial base across the synchondrosis. One end of the staple was placed in the basi-occipital bone and the other end in the basi-sphenoid bone.

Results of this early closure showed marked changes in craniofacial morphology. The entire cranium anterior to the auditory bullae dropped down in relation to the axial skeleton. The cranial base from basion to the intersphenoidal synchondrosis was markedly shortened. …

The Effect Of Neutral Bath In Alleviating Stress Due To Group Psychotherapy, Olga L. Walek, Arlene M. Lee

Loma Linda University Electronic Theses, Dissertations & Projects

A preliminary study showed that the experience of group psychotherapy produced a mean elevation in systolic blood pressure of 4.4 mm. of mercury, and diastolic blood pressure of 3.3 mm. of mercury, and a mean decrease of pulse of 3.0. An experimental study was done by comparing the effectiveness of three procedures; neutral bath, bedrest, and ward activities in lowering blood pressure and pulse after group psychotherapy. Studies had been done to determine stress due to emotional stimuli and its effect upon the physiological and psychological reactions of the body, but there were no actual experimental studies found dealing with …

The Role Of The Articular Eminence In Mandibular Protrusion, Norman E. Corbett

Loma Linda University Electronic Theses, Dissertations & Projects

Since movements of the TMJ may be translatory, rotary, or both, the form of the articular eminence becomes an integral part of the anatomy of the joint and is important in an understanding of TMJ function. A cephalometric technique was developed to accurately determine the anatomical form of the articular eminence. From a series of cephalograms, taken in various mandibular positions, the protrusive condylar path was determined. This path was also determined from a gnathological recording technique. The paths obtained were observed to be the same. The condylar path and articular eminence curves were mathematically expressed by computer programmed quadratic …
