Cardioregulatory Role Of The Abdominal Ganglion Of Aplysia Californica, George Maeda

Loma Linda University Electronic Theses, Dissertations & Projects

An isolated heart-abdominal ganglion preparation of this mollusc was developed and used to study the cardioregulatory function of the ganglion and nerves. The heart was perfused with artificial sea water through an atrial cannula and the gastro-esophageal artery was catheterized for blood pressure monitoring. The presence and cardioregulatory effects of axons in the nerves was investigated by electrical stimulation. Fine-tipped glass microelectrodes inserted into ganglionic neurons were used to determine the relationship between the neuronal and cardiac activities.

The principal results are listed below.

1. Primarily inhibitory responses are obtained from both right and left connective stimulation, with some evidence for …

The Relationship Between Personality Factors Of Collegiate Football Players And Their Effectiveness On The Playing Field, Charles Williams

Masters Theses & Specialist Projects

Through the years there has been increasing interest in the investigation of the athlete's personality. Much emphasis has been placed on the psychological characteristics of athletes of a given age group and ability level. Coaches, trainers, and others involved with athletics believe that personality is an essential ingredient in developing a highly skilled individual. However, the ones in leadership seldom put forth explicit statements of such beliefs into a meaningful theory structure that can be assessed and therefore verified. Statement of the Problem: The purpose of this study was to determine whether differences in personality factors existed between groups of …

Comparison Of The Effects Of 97 Per Cent And 21 Per Cent Oxygen Mixtures Upon Recovery From Treadmill Running Among Male Wrestlers At Utah State University, Michael P. Brooks

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A comparison of the effects on recovery while breathing a 97 per cent oxygen mixture and normal compressed atmospheric air after treadmill running was determined among nine male wrestlers at Utah State University. The variables examined were heart rate and percentages of oxygen and carbon dioxide in expired air. The practice of some athletic teams of administering oxygen to participants during time out periods was the motivation for this study.

A great majority of the studies reviewed conclude that oxygen does not play a significant role in aiding recovery from physical activity.

The experiment first consisted of eight runs on …

The Effects Of Cs Habituation And Duration Of The Directional Modification Of The Cardiac Response In The Guinea Pig (Cavia Procellus), Ray Charles Larson

All Master's Theses

The present experiment examined the effects of CS habituation and two different levels of CS duration (60 versus 6 sec) on the directional modification of the conditioned cardiac response in the guinea pig. The results indicated that the only reaction to the CS, regardless of prior habituation or CS duration, was a decelerative conditioned HR response. However, habituation to a CS prior to classical aversive conditioning was found to attenuate the magnitude of the bradycardia CR that developed. The bradycardia CR was discussed in terms of being a cardiac component of the orienting response.

Hyperactivity In Children, Pat Luttmann

Student Scholarship

The provided document, written in 1971, explores the multifaceted nature of hyperactivity in children, primarily within the framework of minimal brain dysfunction or MBD. The author notes that while these children often appear physically normal, they struggle with a disorganized central nervous system that prevents them from processing environmental stimuli effectively. This neurological impairment manifests as a cluster of symptoms, most notably hyperkinesis, distractibility, impulsiveness, and emotional instability. The text emphasizes that the number of children identified with these disorders is increasing, partly due to medical advances that allow more children to survive difficult births. 

Diagnosis and treatment require a …

Influence Of Temperature Of Incubation And Type Of Growth Medium On Pigmentation In Serratia Marcescens, Robert P. Williams, Cora L. Gott, S M. Qadri, Randolph H. Scott

Faculty, Staff and Student Publications

Maximal amounts of prodigiosin were synthesized in either minimal or complete medium after incubation of cultures at 27 C for 7 days. Biosynthesis of prodigiosin began earlier and the range of temperature for formation was greater in complete medium. No prodigiosin was formed in either medium when cultures were incubated at 38 C; however, after a shift to 27 C, pigmentation ensued, provided the period of incubation at 38 C was not longer than 36 hr for minimal medium or 48 hr for complete medium. Washed, nonpigmented cells grown in either medium at 38 C for 72 hr could synthesize …

Sub-Aversive Response Contingent Foot Shock As A Positive Reinforcer, Robert Lea Fulwiler

All Master's Theses

Forty-eight rats were divided into 8 groups; four were maintained under normal conditions and the other four under sensory deprivation and tested at o, 3, 6, and 9 days after condition institution. The response was placing the head through a hole in the operant chamber and the stimulus (0, 1.2, 4, or 12 Vac) was contingent upon the response. Analysis ot variance disclosed significant differences (p<.01) between the deprived and the non-deprived groups at days 6 and 9; and a significant interaction between deprivation condition and time of test. No differences were shown between the stimulus intensities indicating that the stimulus did not have a reinforcing effect.

The Response Of Gingival Tissues To Alterations In Ph, Robert C. Jann

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to evaluate the histopathological and clinical changes that occurred when a continuous supply of exogenous acid or base, at varying pH, was delivered adjacent to the gingival crest of the monkey. A related goal was to develop a monkey model system which would deliver test solutions continuously and atraumatically, to the experimental gingival sites.

Two young adult female monkeys had a perfusion apparatus attached to certain maxillary teeth so that test solutions were deposited atraumatically to the marginal gingival tissues. During the experimental periods the animals were kept in primate restraining chairs and fed …

Change In The Number Of Fibers And Nuclei In The Rat Soleus Muscle During Normal Development And Increased Work Load Exercise, John K. Pearson

Loma Linda University Electronic Theses, Dissertations & Projects

Many orthodontists have desired to produce a permanent lengthening of a short upper lip. To produce a permanent increase in skeletal muscle mass, changes associated with hyperplasia would probably have to occur. If it would be possible to demonstrate in animals that skeletal muscle cells and corresponding deoxyribonucleic acid (DNA) increased with exercise, clinical studies on the upper lip would be in order.

Male Sprague Dawley albino rats were used to study the effects of exercise and normal development. Increased work load exercise of the soleus muscle was induced by cutting the tendon of the synergestic gastrocnemius. Histological sections of …

A Comparison Of The Articular Eminence To Various Skeletal And Dental Malocclusions, James R. Wise

Loma Linda University Electronic Theses, Dissertations & Projects

The slope of the articular eminence was measured on the cephalograms of 71 subjects. The patients were divided Into three major categories on the basis of skeletal pattern, dental bite type, and Angle's classification. Skeletal pattern was determined by the mandibular plane angle (SNGoGn). High Angle and Low Angle cases were classified by two standard deviations from normal. Dental bite types were divided into Open Dental or Closed Dental according to the absence or presence of anterior disclusion, respectively. Angle's method of classification was also used to divide the sample Into Class I, II, or III malocclusions.

The eminence slope …

The Effect Of Early Postpartum Teaching Of Infant Feeding On Maternal Concern, Linda M. Richter, K. Judy Toews

Loma Linda University Electronic Theses, Dissertations & Projects

An experimental study was conducted on thirty primiparae during the postpartum period to determine if individualized instruction regarding infant feeding would result in a lower level of maternal concern in this area. The study sample was randomly and evenly divided into a control and an experimental group. It was statistically determined that the two groups were homogeneous in regard to age, education, occupation, previous information (prenatal classes and reading) and help at home. The experimental group received individualized instruction by the researchers concerning their chosen method of infant feeding on the second postpartum day. There was no instruction given the …

Using A Participating Relationship To Improve Teen-Age Unwed Mother's Self-Esteem, Linda Gail Reeves

Loma Linda University Electronic Theses, Dissertations & Projects

The study was to provide an approach to help teen-age unwed mothers increase their feelings of self-esteem and thereby attain a conceptual buffer for better coping with life. Self-esteem was defined as individual perception of the worth of oneself relative to that of significant others. The hypothesis tested was that the participating relationship a community health nurse has with a teen-age unwed mother will significantly increase the mother's self-esteem as measured by statistical Q-Sort analysis.

A convenience sample of twenty teen-age unwed mothers was obtained from referrals from San Bernardino County Health, Welfare, and Probation Departments. The girls were between …

The Production Of Acceptable Baked Products In The Electronic Oven, Lois Irene Knudsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose was to find the adjustments needed to make acceptable pies, cookies and muffins baked in the electronic oven. The products were evaluated by a taste panel and by objective tests. The results of both tests supported each other.

The best bottom pie crust had an extra tablespoon of liquid added to the pastry and was precooked before the filling was added. It was both flaky and tender.

No leavening and one-fourth more liquid produced the most acceptable cookies. They were more like standard cookie in height, texture, moisture and tenderness.

It was found that one-half the amount of …

Sterile, 10 per cent non-fat dry milk was inoculated with S. aureus strains capable of producing all types of enterotoxins, and reduced levels of starters; and was incubated at 32 C for 24 hours. The pH and S. aureus population were determined at 2 hour intervals until 8 hours and at 24 hours. The inhibitory response of lactic streptococci was studied by spot-tests on a lawn of S. aureus strains. …

The Effects Of Telone And Related Compounds On The Synthesis And Degradation Of Carotenoids In Plants, David L. Berry

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The incorporation of 3-¹⁴C-,B-hydroxy-, B-methylglutaric acid (HMG) vii into carotenoids of excised etiolated maize shoots, crude cell free extracts and soluble extracts (20, 000 x g) of maize was investigated. HMG was effectively incorporated into carotenoids of excised shoots, crude extracts and soluble extracts. The excised shoots, crude extracts and soluble extracts incorporated 2-¹⁴C-mevalonic acid (MVA) into carotenoids as well. The results indicated the presence of HMG-CoA reductase in the plant as well as an HMG activating enzyme. The soluble extract showed a pH optimum of 7. 0 for incorporation of HMG into …

Antibody Production Of Rats Fed Diets Of Varying Nutrient Density, Radharukmani

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Available evidence indicated that the deficiency of a specific nutrient in the diets adversely affect antibody production from a mild to severe degree. Studies of the effects of diet partially deficient in various essential nutrients on antibody response is meagre.

Twelve groups of weanling rats were fed with diets prepared by diluting the basal diet with 0 to 75 percent sucrose for 46 days and their antibody response was measured on the 28th, 40th and 46th day using Salmonella pullorum as the antigen. The rats fed the diet containing 75 percent sucrose and 25 percent basal diet had mean antibody …

Immunological Response Of Rats Fed Decreasing Levels Of Dietary Iron And Calcium With Or Without Vitamin D, Bernice Nell Neibaur

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A considerable amount of research has shown that a severe dietary deficiency of protein or vitamins will markedly depress antibody synthesis. Very little work has been done with the effect of mineral deficiencies on antibody production, and no evidence has been presented showing the relationship of the effects of small changes in nutrient intake to the sensitivity of the antibody response to small degrees of malnutrition and the relationship of dietary iron, calcium and vitamin D to the production of antibodies.

In two experiments, it was shown that as the level of iron in the diet is decreased, the production …

An Anesthetic Technique Utilizing Innovar, Fentanyl, And Methohexital Sodium For Outpatient Oral Surgery, Fredric D. Haerich

Loma Linda University Electronic Theses, Dissertations & Projects

A study of 800 patients ranging in age from seven to one hundred years was conducted in the development of an anesthetic technique which combines the desirable qualities of a neuroleptic agent with the requirements of an outpatient oral surgical anesthetic. These requirements included rapidity of onset, effectiveness of action, ease of controlling duration, and rapid postoperative recovery.

Patients who were cleared medically for outpatient procedures were given Innovar 1.5 cc/150 lb of body weight, atropine 0.4 mg, and fentanyl 1.0 cc/150 lb of body weight as an initial dose within 30-45 seconds in a D5W drip by means of …

Histopathological Variations Of Periapical Granulomas And Radicular Cysts, Thanapen Kanchanasut

Loma Linda University Electronic Theses, Dissertations & Projects

The periapical dental granuloma and cyst is the most frequent sequela of pulpitis. These lesions are always intraosseous and often become quiescent after the acute phases are over, forming a space which primarily consists of chronic inflammatory tissue. This chronic inflammatory tissue usually appears as a one-centimeter area of punched out bone on the x-ray film and is referred to as a dental granuloma. Should epithelium choose to proliferate in this inflammatory area, it may undergo subsequent cystic degeneration forming the typical periapical cyst. While much has been written with regard to the etiology and treatment of the apical cyst …

A Serial Cephalometric Evaluation Of The Mandibular Radius, W. Thomas Veal Jr.

Loma Linda University Electronic Theses, Dissertations & Projects

This study compared the mandibular radius (center of the condyle to gnathion) with the mandibular planes (lower border and GoGn) utilizing serial lateral cephalograms on orthodontically treated and nontreated individuals. Three groups were employed as follows: Group 1 of 38 untreated individuals for serial data on growth alone; Group 2 of 13 patients with Class II, high angle, open bite malocclusions that had been treated with high pull headgear and the edgewise appliance (control representing the least amount of mandibular rotation during orthodontic treatment); and Group 3 of 54 randomly selected orthodontic patients to represent the average mandibular rotation during …

A Comparison Of Various Teaching Methods For Patients With Chronic Obstructive Pulmonary Diseases, B. Carol Altizer, Nancy S. Bailey

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to find out whether patients with chronic obstructive pulmonary disease (C.O.P.D.) learn more from auditory or from visual teaching. Of the 30 patients in the sample, 10 used a programmed instruction booklet, 10 used a taped recording of the same programmed material and 10 were in a control group which received no specific teaching.

A pre-test was given to each of the patients who met the criteria for the study. One researcher gave the pre-test through an oral interview with the patient. After the pre-test, the patient received the teaching device assigned to him …
