The four solutions (1, 10, 100 μg/ml endotoxin, and saline) were then injected into the four prepared teeth for each cat and the access cavities sealed with IRM.

At two week intervals, two cats were sacrificed and the specimens removed, while the remaining animals were retreated as previously described. The block tissue sections were radiographed, fixed in 10% buffered formalin, and prepared for …


The Acquisition Of Five Specific Morphemes By English-Speaking Preschool Children, Maxine Ulyate Jun 1979

The Acquisition Of Five Specific Morphemes By English-Speaking Preschool Children, Maxine Ulyate

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of the present research was to study the acquisition of the morphemes involved in the production of the noun plural and possessive, the present progressive tense, the third person singular of the verb and the regular past tense. Research had documented that a time lapse existed between the time that a child was able to correctly inflect a common English word and when he could correctly inflect a phonetically similar nonsense item. This lapse appeared to be the time during which the child formulated an internal rule for the production of each morpheme.

The methodology involved testing sixty …

A Comparative Analysis Of Intrusion Of Incisor Teeth Achieved In Adults And Children According To Facial Type, Ronald L. Otto Jun 1979

A Comparative Analysis Of Intrusion Of Incisor Teeth Achieved In Adults And Children According To Facial Type, Ronald L. Otto

Loma Linda University Electronic Theses, Dissertations & Projects

A comparison of incisor intrusion achieved in deep bite adults and children was made. Facial type was also examined for affect upon intrusion achieved. Fifty-five cases treated with Bioprogressive mechanics were studied cephalometrically, including twenty-four adults and thirty-one children. Neither age nor facial type was found to be statistically related to the amount of incisor intrusion achieved in this sample. A method of measuring intrusion at the root apices was devised which was felt to give a more accurate indication of actual bodily intrusion. More external root changes during treatment were observed for adults than for growing children. Wide latitude …


The Effects Of Orally Administered Charcoal On Intestinal Gas, Herbert J. Thompson Jun 1979

The Effects Of Orally Administered Charcoal On Intestinal Gas, Herbert J. Thompson

Loma Linda University Electronic Theses, Dissertations & Projects

Our primary objectives were to determine if orally administered charcoal effectively decreased intestinal gas, and relieved subjective symptoms associated with a high gas producing meal.

The adsorptive properties of charcoal for those gases usually found in intestines (CO2, H2, CH4, H2S) were first tested by placing measured samples of each gas alone with weighted samples of activated charcoal in a respirometer.

The degree of adsorption of each gas by charcoal was determined. Charcoal effectively adsorbed H2 and CO2.

A group of normal human males were fed a gas producing …

Fatigue Properties Of Orthodontic Wire, Kirkland B. Reuer Jun 1979

Fatigue Properties Of Orthodontic Wire, Kirkland B. Reuer

Loma Linda University Electronic Theses, Dissertations & Projects

Fracture of orthodontic appliances can be a problem because of the time involved to replace and repair them. It has been shown that most failures have been a result of fatigue fracture, i.e., failure resulting from cyclic loading.

The purpose of this study was to determine what effect variation of the type of orthodontic wire and heat treatment had on fatigue resistance. A device was constructed to put a cyclic load on a piece of wire until fracture. Two types of cobalt-chromium alloy wire (Blue and Green Elgiloy from Rocky Mountain Orthodontics) and three types of stain less steel wire …


The Effect Of Primary Nursing On Nurse Job Satisfaction And Patient Satisfaction With Nursing Care, Karen Garrison Jun 1979

The Effect Of Primary Nursing On Nurse Job Satisfaction And Patient Satisfaction With Nursing Care, Karen Garrison

Loma Linda University Electronic Theses, Dissertations & Projects

Nursing as a profession has seen the loss of large numbers of practitioners through job dissatisfaction. In addition, recent studies testing professional growth among new graduates have demonstrated negative findings. Lack of responsibility and accountability have been indicated as potential causes of these problems which confront professional nursing.

In nursing modalities such as functional, case method and team nursing the lack of autonomy in providing care is visible. The team nursing approach fragments patient care; a nurse in this system is responsible for team members rather than directly for patients. The registered nurse does not have enough personal contact in …

Sensory Stimulation To Promote Deep Breathing In The Chronic Obstructive Pulmonary Disease Patient, Sharon Kay Sauer Dec 1978

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 …


Ultrastructural Study Of Wound Healing On A Root Planed And Citric Acid Treated Root Surface, Craig Martin Ririe Sep 1978

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 …


Isolation And Chemico-Physiologic Characterization Of A Parotid Hormone Activity From Porcine Glands, Jean-Marc Tieche Sep 1978

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. …


New Attachment Of Connective Tissues To Human Teeth Involved In Chronic Periodontal Disease : A Histologic Study, Rick Cole Aug 1978

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 …

Effects Of Heat Treatment On The Mechanical Properties Of Chromium-Cobalt Alloy Wire, Robert L. Nations Jun 1978

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 …
