Mandibular Nerve Regeneration Through Solid And Canalized Bone And Plaster Grafts, Lawrence D. Day

Loma Linda University Electronic Theses, Dissertations & Projects

Utilizing an extra-oral approach and sterile technique, left mandibular ostectomy was performed on five miniature pigs. The segment removed was 3 cm long and included the inferior border, mandibular canal and, in some cases, apices of a molar tooth.

Bone and plaster grafts (one solid and one canalized of each) were used to fill these defects. The fifth was left with no graft.

The objective was to learn the effect of each of these procedures on regeneration of the mandibular nerve across the defect. It was hypothesized that canals through the grafts would facilitate regeneration.

X-rays were taken periodically. The …

The Clinical Use Of Fluorine18 In Bone Scanning, R. A. Gatesi, A. T. Vulpetti, T. L. Kosnik, W. G. Tucker, R. W. Talley

Henry Ford Hospital Medical Journal

Roentgenograms are frequently inadequate in the detection of early osseous metastases. Isotope bone scan is a more sensitive diagnostic procedure. Reported here are findings on 40 patients with known or suspected osseous involvement using the short-lived radionuclide 18F. Comparison with standard roentgenograms and clinical follow-up demonstrated 11 early detections. 18F was found to be a very suitable agent for isotope bone scanning. Ilustrative cases are presented

Studies Of The Electrical Parameters And Behavioral Effects Of An Eeg ''Seizure Discharge", W. R. Mccrum, R. M. Lee, H. Van Den Ende, L. D. Proctor, J. A. Lee

Henry Ford Hospital Medical Journal

Nemastrina monkeys with multiple electrodes implanted in the amygdaloid area of the brain were used to study the relationship of electrical seizures and overt behavior. The electrical seizures were produced by long duration electrical pulses administered through the implanted electrodes. There appears to be no relationship between this kind of electrical seizure and lever pressing performance. Relationships between depth EEG, depth impedance, DC potential and surface EEG are observed and as a consequence some ideas concerning the genesis of the electroencephalogram are put forth.

Histopathological Response Of The Human Tooth To An Intrapulpal Pin Implantation, Raymond W. Dolph

Loma Linda University Electronic Theses, Dissertations & Projects

This investigation was designed to serve as a research project directed toward the study of histopathological response of human teeth to the intentional implantation of threaded, stainless steel, gold plated pins into the vital pulp.

Pins of several types are currently used in several aspects of restorative and periodontal dentistry. In some cases there may be unintentional perforation of the dental pulp. In other cases it may be advantageous to purposely perforate the pulp for added retention. The purpose of this research is to help determine the reaction, possibilities, and prognosis of such technique.

Human teeth selected for experimental and …

The Development And Evaluation Of A Manual For Use In Community Nutrition Education Classes, Helen H. Register

Loma Linda University Electronic Theses, Dissertations & Projects

A manual was prepared and evaluated for use by non-professional personnel in community nutrition education. Instruction and suggestions were given for organizing these classes and techniques outlined for food demonstrations. Material was written for lectures and tests on eight nutrition topics, with visual aid suggestions, recipes and "chatter" to accompany the recipes.

The material was tested by presenting three of the eight topics before audiences. Volunteer non-professional teacher-demonstrators gave the presentations which were evaluated by test scores from the audiences, by score forms from each teacher-demonstrator, and by evaluation sheets from the advisory committee.

On the basis of the evaluation, …

The Reaction Of Dog Tongue To Syrijet Injections, Donald L. Peters

Loma Linda University Electronic Theses, Dissertations & Projects

Tissue response toward injection by a "fluid-pressure" type apparatus, the Mizzy Syrijet, was evaluated by using dogs as the experimental animal.

The tongue was the organ of choice because it's size is sufficient to allow for several injections without overlapping tissue responses. In addition the two halves of the tongue are anatomically separated by a median raphe, providing for further isolation of injections.

The animals were injected at 12, 24, 48, 72 and 96 hour intervals utilizing the Syrijet on the right side of the tongue and needle on the left. Needle injection served as control for the microscopic comparison. …

Analgesic Effectiveness As Measured By A New Algesiometer, J. Raymond Wahlen

Loma Linda University Electronic Theses, Dissertations & Projects

A method of measuring the effectiveness of analgesics using a new instrument, known as the Algesiometer,* is described. The instrument, utilizing an electrical stimulus, produced an experimental pain when attached to the skin over the mid shaft of the tibia. The patient, who was experiencing a pathological pain, gradually increased the experimental stimulus, by turning a control rheostat, until it was equal in intensity to the pathological, or clinical, pain. The intensity of the stimulus was calculated in milliwatts and consisted of a rectangular wave pulsating direct current of approximately one millisecond duration and an interval of nineteen milliseconds.

Some Aspects Of Cranial Bone Growth In The Puberal Macaca Mulatta Monkey: As Evidenced By Metallic Implants And Cephalometric Roentgenography And The Application Of A Geological Lapidary Technique For The Semi-Serial Thin Sectioning Of Undecalcified Bone, Lee Eugene Olsen

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to investigate cranial and facial bone growth in the puberal Macaca mulatta monkey over a six month period utilizing the methods of metallic implantation combined with serial cephalometric roentgenography and a bichromatic vital staining method.

The employment of the vital stains, alizarin Red S and anthracene blue, over the six month period of the study, failed to stain the actively growing bone as evidenced by gross and microscopic analysis of the undecalcified bone preparations.

Interimplant measurements were made across certain bone sutures and the following results were obtained: The zygomaticotemporal sutures showed marked growth …

The Effect Of Removing The Crevicular Epithelium Upon Canine Tooth Replantation, Leon A. Leonard

Loma Linda University Electronic Theses, Dissertations & Projects

The nature of epithelium and the remarkable facility with which it aggressively covers granulation tissue, suggests that removal of the sulcular epithelium surrounding the extraction wound of a tooth to be replanted could promote reattachment of the periodontal tissues at a more nearly ideal coronal level. To investigate this hypothesis twenty mature teeth in five mongrel dogs were experimentally replanted. One half of them were replanted in alveoli around which the crevicular epithelium had been removed, the remaining teeth without creviculoectomy acting as controls. Animals were euthanized at one, two, three, five, and sixteen weeks. After clinical evaluation of the …

A Cephalometric, Anatomic And Histologic Investigation Of The Effects Resulting From A Heavy Interrupted Orthopedic Force To The Maxilla Of The Macaca Mulatta Monkey, Roger Wayne Triftshauser

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to determine changes that occur in the craniofacial complex, when a heavy interrupted orthopedic force is employed to retract the maxilla in the post puberal rhesus monkey. Cephalometric, histologic and anatomic examinations were utilized to substantiate the findings.

Four female rhesus monkeys were used for experimentation. Two were experimental animals and the other two controls. Cervical retraction with headgear was applied over a period of 313 days and 159 days to the two experimental animals. Forces not exceeding 2.5 lbs. were found most effective.

The findings were as follows:-

1. A total posterior displacement of …

Hormonal Regulation Of Lipolysis And Phosphorylase Activity In Human Fat Cells, Jay Moskowitz, John N. Fain

Faculty Publications

A B S TR A C T Prostaglandin E₁ (PGE₁) at a concentration of 1 ng/ml antagonized theophylline, and norepinephrine induced release of glycerol and free fatty acids (FFA) in human fat cell preparations. Insulin at higher doses also inhibited theophylline-stimulated lipolysis. The N₆-2-O^'dibutyryl derivative of cyclic adenosine monophosphate (DCAMP) stimulated lipolysis. Prostaglandin E1 did not significantly inhibit the lipid mobilizing effects of DCAMP. Changes in glycogen phosphorylase activity after treatment with theophylline, norepinephrine, DCAMP, and PGE₁ paralleled those of lipolysis. These results suggest that in man as in experimental animals lipolysis …

Effect Of Different Levels Of Dietary Protein And Sex Hormones On Lipid Metabolism In Male Castrated Rats, Sharad Patel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Male castrated rats treated with testosterone or estradiol were given a diet containing 9, 18, or 50 per cent protein. Total lipids, lipid classes and fatty acid composition of lipid classes were determined.

Estradiol treated rats grew slower, smaller and consumed less diet. Their liver weights were larger when compared to their body weights. Moisture content of liver remained unaffected by sex hormones, but increased with the high level of protein in the diet.

Both testosterone and estradiol affected lipid metabolism; in general, the estrogenic influence was more pronounced and more predictable. Estradiol administration increased total lipids, free and esterified …

An In Vivo Perfusion Apparatus For Studies On Gingival Disease : Assessment By A Perfusion Of Nonspecific Proteolytic Enzymes, Don Dornan

Loma Linda University Electronic Theses, Dissertations & Projects

This thesis describes an in vivo perfusion apparatus which can continuously deliver controlled quantities of solutions to localized, contralateral intra oral areas in albino rats. Three animals were per fused on the experimental area (the mesial sulcular area of the maxillary first molar) on one side with tap water and trypan blue. Localization of the solution delivered and minimal histological changes due to the presence of the apparatus was demonstrated on these animals. A 1% solution of trypsin was perfused on the experimental area of one animal for one day at the rate of 4.8 ml/day and on another animal …

Dietary Factors And Induction Of Hepatic Microsomal Hydroxylative Enzymes By Organochlorine Pesticides, D. Jesse Wagstaff

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Induction of hepatic microsomal hydroxylative enzymes is an important aspect of detoxication of fat-soluble toxicants. The magnitude of induction depends on numerous factors, such as the nature and dose of toxicant as well as dietary factors. Research was conducted on (1) endrin tolerance in rats, (2) preliminary comparisons of inductive effects of various organochlorine pesticides in rats to select compounds for further study in guinea pigs, (3) general effects of various dietary factors on induction, and (4) effects of ascorbic acid deficiency on induction of hepatic microsomal hydroxylative enzymes by organochlorine pesticides in guinea pigs. Measurements were made of body …

Role Of Lamb Pregastric And Gastric Extracts In Cheese Manufacture, Ramjibhai V. Chaudhari

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Lamb pregastric (PGE) and gastric extracts (GE) have been evaluated for their role in Italian cheese flavor production. Both have been shown to produce increases in free fatty acids and in non-protein-nitrogen during incubation with milkfat and casein substrates as well as in cheese substrates. Gastric lipase and cathepsins are considered to be the additional active agents in GE. Parmesan cheese manufactured with PGE and GE added to the curd was superior in flavor when both were employed, and either extract alone was better than the uninoculated control. An assay for GE proteolytic activity has been proposed which involves the …
