Parental Perception Of The Neonate, Liza Ann Webb

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to determine maternal and paternal perceptions of the neonate. The Broussard Neonatal Perception Inventory was used to measure perception.

Thirty couples who delivered normal, healthy, first-born infants at a Naval Hospital in San Diego volunteered for the study. Consent forms were signed during the hospital stay and the Broussard Neonatal Perception Inventory was administered to both parents in the homes when the infants were one month old.

Statistical analysis of data showed that mothers and fathers did rate their one-month-old infants as above the average infant using the Broussard Neonatal Perception Inventory. The range …

Sensory Stimulation To Promote Deep Breathing In The Chronic Obstructive Pulmonary Disease Patient, Sharon Kay Sauer

Loma Linda University Electronic Theses, Dissertations & Projects

Breathing retraining has been an integral part of respiratory rehabilitation for the patient with chronic obstructive pulmonary disease (C.O.P.D.). Techniques used for breathing retraining have been studied for many years. These techniques include such breathing retraining modalities as relaxation conditioning, positioning maneuvers, abdominaldiaphragmatic breathing, pursed lip breathing and intermittent positive pressure breathing. Controversy concerning the therapeutic value of many of these techniques has developed. In this descriptive case study on three subjects with C.O.P.D. the experimental technique of sensory stimulation was investigated as a breaching retraining method. Sensory stimulation consisted of five minutes of repetitive brushing and two to three …

Isolation And Chemico-Physiologic Characterization Of A Parotid Hormone Activity From Porcine Glands, Jean-Marc Tieche

Loma Linda University Electronic Theses, Dissertations & Projects

For the past decade, evidence has accumulated which suggests that the resistance of the teeth to dental decay is in part under systemic control. It was shown that the resistance is accomplished through the optimal operation of a dentinal fluid transport mechanism which is believed to be hormonally controlled by the hypothalamic-parotid gland endocrine axis. Although circumstantial evidence for such an endocrine function was strong, the isolation of a parotid hormone which stimulates the dentinal fluid transport mechanism remained to be accomplished.

Using modern biochemical techniques, a methodology was designed to isolate and purify the hormone from porcine parotid glands. …

Ultrastructural Study Of Wound Healing On A Root Planed And Citric Acid Treated Root Surface, Craig Martin Ririe

Loma Linda University Electronic Theses, Dissertations & Projects

It has been shown previously that a root surface which has been scaled, root planed and demineralized by topical application of citric acid in vitro, is dominated by exposed collagen fibrils. The purpose of this study was to examine the mechanism of healing and possible reattachment of soft periodontal connective tissue to the root planed and subsequently acid treated root surfaces and to determine whether new collagen fibrils produced in the connective tissue could attach to these exposed fibrils.

Full thickness tissue flaps were raised and the coronal 4-5 mm of the labial alveolar plate removed over the maxillary incisor …

New Attachment Of Connective Tissues To Human Teeth Involved In Chronic Periodontal Disease : A Histologic Study, Rick Cole

Loma Linda University Electronic Theses, Dissertations & Projects

Reconstruction of the periodontium destroyed by periodontal disease may be considered an ultimate goal of reconstructive periodontal therapy. To date, there has been no concrete evidence demonstrating this phenomenon in humans. Garrett (1978) has shown that citric acid, after application to root planed tooth surfaces, produces a four micron wide demineralized zone which is characterized by exposed collagen fibers. It is impossible that this demineraIization may lead to new attachment by enhancing cementogenesis or by exposing root surface-fibers which by simple fibrogenesis may splint to fibers of the healing surgical wound. Register (1973) and Register and Burdick (1975) have reported …

Tensile Properties Of Stainless Steel Orthodontic Wire, Elbert E. Jackson

Loma Linda University Electronic Theses, Dissertations & Projects

Ten types of .020 inch stainless steel wire were compared using a tensile test. The wires were tested in the as-received condition and after heat treatment at 750°F for eleven minutes. The data were then analyzed statistically using the general linear hypothesis.

In the as-received condition each of four mechanical properties--elastic modulus, 0.2 per cent yield strength, tensile strength, and percent elongation--was found to vary significantly from one type to another.

When subjected to heat treatment, the elastic modulus proved to be the most stable of the four properties, changing only slightly in three cases. There was no significant change …

Effect Of Storage On The Elastic Properties Of The Red Cell Membrane, Caroline M. Ballweg

Loma Linda University Electronic Theses, Dissertations & Projects

The goal for the preservation of blood is the optimal survival and function of the stored blood after reinfusion. In vivo means of assessing viability after storage would be ideal but these survival studies are expensive, involved, and not without danger. Thus, in vitro means have been sought to evaluate preservation. The most frequently used of the in vitro tests for predicting red blood cell survival is deformability.

This study applies a recently developed method of measuring deformability to assess changes in stored blood. In brief, the method involves drawing a "mini" unit of blood from each of three normal …

Development Of A Short Form For The Carrow Elicited Language Inventory, Janet Lee Lawson

Loma Linda University Electronic Theses, Dissertations & Projects

This investigation was designed to determine if a shortened or screening form could be developed for use with the Carrow Elicited Language Inventory (CELl) at the first grade level. The sample for this research was comprised of fifty-six children between the ages of 5 years 9 months and 6 years 9 months. The children were chosen according to availability and time factors and came from middle socioeconomic backgrounds.

All subjects were tested with the CELl. After selection of items for the short form, each child's score on the short form was compared with his score on the CELI with the …

Stress Analysis Of Post And Crown Restorations Of Endodontically Treated Teeth, Ronald C. Hansen

Loma Linda University Electronic Theses, Dissertations & Projects

Forty-four similar sized maxillary lateral incisor teeth were randomly divided into four equal groups to test their resistance to fracture. Group 1 teeth were the controls, no treatment was done. Group 2 teeth consisted of endodontically treated teeth, restored with composite resin in the access opening. Group 3 teeth were endodontically treated and restored with a post and flat surface standardized aluminum crown. The teeth in Group 4 were endodontically treated and restored with a post and composite resin core buildup with a cast gold crown. The metal collar of gold incorporated 1.5 mm of tooth structure below the core …

Comparison Of Root Surfaces In Endodontic Lesions, Periodontic Lesions And Normal Human Teeth, Robert W. Hanson

Loma Linda University Electronic Theses, Dissertations & Projects

The healing potential of an endodontic lesion is usually greater than a periodontic lesion (Simon et al. 1972; Hiatt 1977). Periodontal regeneration places particular emphasis on the soft tissue-tooth interface (Stahl 1977). This interface was examined in fifteen extracted human teeth.

The teeth were divided into three groups: (1) periapical lesions, (2) periodontal lesions, and (3) healthy periodontal tissue. Criteria were established for each group. Freshly extracted human teeth meeting the criteria were fixed in gluteraldehyde or paraformaldehyde. The teeth were then selected for surface observation or cracked for cross sectional examination. The teeth were post fixed, dehydrated, and coated …

Utilization Of Dietetic Technicians In Hospitals, Elmer Beck

Loma Linda University Electronic Theses, Dissertations & Projects

There is a shortage of educationally qualified dietetic technician personnel in the health care industry. The job opportunities for dietetic technicians exceed the supply. Because of this shortage and the need to deliver high quality nutritional care to individuals and groups, dietitians should function at the highest level of professional competency. To accomplish this goal requires delegating certain routine task functions to the dietetic technician.

The purpose of this research was to determine the degree of change between 1973 to 1977 in the willingness of dietitians to delegate task function to the dietetic technician. The instrument used to collect data …

A Clinical Method For Predicting Orthodontic Band Sizes, Robert P. Mohr

Loma Linda University Electronic Theses, Dissertations & Projects

A correlation was established among the orthodontic band sizes in a given individual. The original sample contained 258 data sets (Unitek Corp. band sizes from first molar through the first molar in both arches) which were computer analyzed. The maxillary right central incisor band size was selected as the "predictor size" for a band size prediction table developed from this study.

An additional 56 data sets were tabulated and became the test sample to test the accuracy of the band size prediction table. Band sizes of the test sample were predicted within ±1 band size 66% of the time and …

Effects Of Trypanosoma Musculi Kendall, 1906 Immune Serum On The Reproduction Of Trichinella Spiralis (Owen, 1835) Railliet, 1896 In Mice, Samuel L. Chafin

Loma Linda University Electronic Theses, Dissertations & Projects

The possible effects of ablastin, a reproduction-inhibiting antibody which is produced during the infection of the blood parasite, Trypanosoma musculi in the mouse, were investigated by fractionating the parasite into a supernatant fraction (designated as Group A test mice) and a pellet fraction (Group B test mice). These groups A and B mice were injected with the respective fractions, plus Freund’s Complete Adjuvant (FCA). Control mice were injected with FCA only. Sera from these three groups of mice were removed after the Group A and Group B mice were shown to be negative to T. musculi challenge, and Group A …

Cranio-Facial Skeletal Morphology Of Digit Suckers, John Eric Peterson Jr.

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this paper was to investigate the cranio-facial skeletal morphology found in digit suckers.

The criteria used for selecting the 50 patients in this study were a history of digit sucking and an anterior dental open-bite. The sample consisted of Class I and Class II, Division 1 malocclusions, ages six through adult, for both sexes. If an individual was post— pubertal, they were classified as an adult. A Ricketts lateral cephalometric analysis of each patient was compared to standards of the same age. These differences were analyzed statistically with a Student t test and a one-way analysis of …

Effects Of Heat Treatment On The Mechanical Properties Of Chromium-Cobalt Alloy Wire, Robert L. Nations

Loma Linda University Electronic Theses, Dissertations & Projects

Since virtually all stages of orthodontic treatment involve forces obtained from deformed metallic materials, an understanding of properties of metals is an important part of orthodontics. The use of chromium-cobalt alloy for arch wires is relatively new to the field, and more needs to be known about its use in order to get the most from this product.

Many clinicians feel that advantages can be gained through a low temperature heat-treatment to change certain mechanical properties of the material. A tensile test was chosen in the attempt to learn more about this alloy in the untreated form as well as …

Computer Modeling Of Cardiac Electrical Activity By Polarcardiogram Patterns, Daniel K. Berry

Loma Linda University Electronic Theses, Dissertations & Projects

The objective of this thesis is to provide for the cardiologist polarcardiograms and additional diagnostic criteria which will enable him to diagnose heart disease more easily. Other contributions are those of: (a) providing a system of data acquisition and (b) analyzing Dr. Gordon Dower’s criteria for myocardial infarction using the programs provided in this thesis.

The problem inherent in the reading of a polarcardiogram is the identification of the "loop" patterns with the associated heart disease. This can be accomplished by reading and interpreting both vectorcardiograms and electrocardiograms as well as angiograms, then relating the interpretation to the polarcardiogram patterns. …

Effect Of Time And Diet On The Immune Status Of Mice Challenged With Herpes-Transformed Cells, Daila S. Gridley

Loma Linda University Electronic Theses, Dissertations & Projects

Human Herpes simplex virus type 2 (HSV 2)-transformed Balb/c mouse cells (H238 cells) are malignant in Balb/c mice. The immune stratus of mice bearing H238 cell-induced tumors was studied and changes in immune response with time and with altered diet of the mice were measured.

In the experiments dealing with the status of immunity with time after tumor cell injection, mice were fed Purina Laboratory Chow (P.L.C.), injected with H238 cells, and sacrificed three to eight weeks post-injection. In the diet experiments, groups of mice were fed either P.L.C. or one of six equicaloric diets, consisting of low or high …

The Stability Of Expanded Mandibular Canines, Premolars, And Molars Concomitant With Rapid Midpalatal Expansion, Ralph S. Kurti

Loma Linda University Electronic Theses, Dissertations & Projects

The view of not expanding mandibular canines to accommodate incisor crowding because of the fear of relapse of of the incisors has been generally accepted in orthodontics for many years. Most studies that have investigated expanded mandibular canine stability have concluded that they could not be permanently expanded to any degree. By adding another variable (rapid midpalatal expansion) to canine expansion it was thought that this might possibly increase canine expansion stability.

The purpose of this research was to determine if the stability of the expanded canines through 1st permanent molars was enhanced by concomitant rapid expansion of the midpalatal …

The Effect Of Perceptual Set On Listener Judgments Of Voice Quality Deviations, Patricia M. Hansen

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to test the possible influence of perceptual set on listeners' judgments of voice quality deviations. Perceptual set was created by instructions given to an experimental group which limited their choices, thus encouraging a particular response. The effect of set on the overall performance of the group, on backward versus forward voice samples and on the level of experience of the listener were all investigated.

The sample for this study was comprised of 24 students of speech pathology and audiology. The subjects were divided into matched experimental and control groups and asked to listen to …

The Effect Of Preoperative Instruction And Unit Orientation On Selected Postoperative Factors Of Nonemergency Critical Care Surgical Patients, Sharon Stephens Espersen

Loma Linda University Electronic Theses, Dissertations & Projects

The intensive care unit's effect on the patient has become a subject discussed often by nurses and other health team members. One of the nursing interventions that has been implemented to attempt to de crease the potentially harmful environmental effects of the ICU on the patient is orienting the patient about what to expect prior to the ICU admittance.

A major problem is that most intensive care unit (ICU) patients are admitted to the unit on an emergency basis. Few studies, therefore, have focused on the effects of preoperative instruction of ICU patients. The studies that have been done were …

Performance Of Task Functions By Dietetic Technicians, James C. Rose

Loma Linda University Electronic Theses, Dissertations & Projects

The effective use of professional dietitians is predicated on the effective delegation of less demanding responsibilities and routine tasks to educationally qualified dietetic technicians. This is essential to effect optimal nutrition care at lowest cost.

The purpose of this research was to determine the degree to which dietetic technicians were performing identified tasks of the role as defined by the American Dietetic Association. A questionnaire was the survey instrument used to collect data from the 130 dietetic technicians who were members of the American Dietetic Association.

Task scores were derived by determining the average per cent of listed functions the …

Phytate Extraction And Stimulation Of Phytase By Zn & Mg In Seeds, Sandra Gin-San Chow

Loma Linda University Electronic Theses, Dissertations & Projects

Almonds, peanuts, mung beans and soy beans were soaked in distilled water for 0, 2, 6, 18 and 24 hours, and the phytate in the seeds and in the soak water was quantitatively analyzed. A comparison of phytate content was made after the seeds were soaked in 0.01 N HCl or in saturated NaHco 3. The seeds soaked in distilled water served as controls. The effects of zinc and magnesium on stimulation of phytase in seeds were determined by comparing the quantity of substrate (phytate) with that of the control group.

The method for analyzing the phytate content was based …
