The Effect Of 72 Consecutive Hours In The Coronary Care Unit On The Night Sleep Of 10 Patients Age 65 And Older, Eugenia J. Creason Dec 1977

The Effect Of 72 Consecutive Hours In The Coronary Care Unit On The Night Sleep Of 10 Patients Age 65 And Older, Eugenia J. Creason

Loma Linda University Electronic Theses, Dissertations & Projects

The prevalence of heart disease in the population over age 65 has contributed to the increasing number of aged patients hospitalized in critical care units (Gsell, 1977). Changes which occur in the process of aging and in cardiac disease should be considered when providing nursing care to these patients. A disturbance in the sleep wakefulness cycle resulting in a decrease of restorative sleep is a major change occurring at age 65 and after (Feinberg, 1967). The cardiac patient finds that it takes longer to go to sleep, and then awakens often during the night (Karacan et al., 1969).

The Effect Of Endodontic Therapy On The Incidence Of Radiation Caries In Dogs, James A. Abbott Jun 1977

The Effect Of Endodontic Therapy On The Incidence Of Radiation Caries In Dogs, James A. Abbott

Loma Linda University Electronic Theses, Dissertations & Projects

Endodontic therapy was evaluated as a possible control or prevention modality of radiation type dental caries in dogs. Two adult male dogs with permanent dentitions had endodontic therapy performed on alternating teeth in each jaw. The nontreated teeth served as controls.

The dogs were irradiated with 7000 rad Cobalt-60 radiation fractionated over an eight week period. The dogs were killed at 60 and 182 days post-irradiation. The teeth were removed from the jaws and immersed in methylene blue dye, sectioned, and the dye penetration pattern photographed. Diffusion of the dye into the tooth structure was quantified and statistically analyzed.

Hallucinogens: A Cause Of Convulsive Ergot Psychoses, Sylvia Dahl Winters Jun 1976

Hallucinogens: A Cause Of Convulsive Ergot Psychoses, Sylvia Dahl Winters

Loma Linda University Electronic Theses, Dissertations & Projects

Ergotism with vasoconstriction and gangrene has been reported through the centuries. Less well publicized are the cases of psychoses associated with convulsive ergotism. Lysergic acid amide a powerful hallucinogen having one.-tenth the hallucinogenic activity of LSD-25 is produced by natural sources. This article attempts to show that convulsive ergot psychoses are mixed psychoses caused by lysergic acid amide or similar hallucinogens combined with nervous system lesions secondary to vasoconstrictive effects of ergotoxine.

The Effect Of Masking On The Acoustic Reflex Threshold, Nancy E. Aldrich Jun 1975

The Effect Of Masking On The Acoustic Reflex Threshold, Nancy E. Aldrich

Loma Linda University Electronic Theses, Dissertations & Projects

This study investigated the effect of masking noise on the threshold for stapedial reflex. It has been shown that masking which shifts the hearing threshold causes a loudness function typical of recruitment. It was hypothesized that the stapedial reflex threshold remains the same in a masked situation as in the unmasked situation . It was suggested that this demonstrates recruitment in that the presence of noise reduces the range between hearing thresholds and stapedial reflex thresholds.

Ten subjects, with no known hearing loss or pathology involving the ear or reflex arc were used in this study. A 1000 Hz tone …


Sexual Parameters In Doctor-Patient Relationship, Judith Adams Perry Jun 1975

Sexual Parameters In Doctor-Patient Relationship, Judith Adams Perry

Loma Linda University Electronic Theses, Dissertations & Projects

A survey to determine the attitudes and practices of physicians regarding touching (erotically and nonerotically) their patients was conducted with 164 female physicians. The results were compared with a previous study (from the University of California, Los Angeles) of male physicians. As compared with the UCLA sample of male physicians, more female physicians believe in and engage in nonerotic touching; but fewer female physicians believe in and engage in erotic touching. None of the female physicians reported sexual intercourse with their patients as compared with 33 or 11% of the UCLA sample of male physicians.

The Relationship Of Locus Of Control Of The Diabetic Patient And Compliance With Medical Regimen, Lois Daniel Mar 1975

The Relationship Of Locus Of Control Of The Diabetic Patient And Compliance With Medical Regimen, Lois Daniel

Loma Linda University Electronic Theses, Dissertations & Projects

The literature indicates that many diabetic patients do not adhere to their prescribed medical regimen and that there is a need to discover factors that stimulate compliant behavior. It has been proposed that the patient's decision to accept or reject treatment has many determinants. This study explored the effect of one such determinant, the locus of control (the source of the stimulus for a person's behavior). It was hypothesized that a person with an internal locus (one who believes his actions influence his future) would be more likely to comply with a medical regimen than one with an external locus …


The Effects Of Progressive Relaxation And Myoelectric Feedback On Respiratory Resistance In Bronchial Asthmatics, Daphne Browne Shah Nov 1974

The Effects Of Progressive Relaxation And Myoelectric Feedback On Respiratory Resistance In Bronchial Asthmatics, Daphne Browne Shah

Loma Linda University Electronic Theses, Dissertations & Projects

For the individual with bronchial asthma, an asthmatic attack can be a life threatening experience. A theory of bronchial asthma as a conditioned response has been recently proposed by several investigators. It was suggested that this conditioned response may be modified by lowering the arousal level, and as a result, decreasing the asthmatic response.

The problem identified in this exploratory study was to measure the effects of relaxation on the smaller or peripheral airways of a convenience sample of six asthmatic subjects fourteen to seventy years of age. It was hypothesized that an increased degree of total body relaxation would …


Prenatal Instruction Of Breast Feeding Mothers, Anita Berry Sep 1974

Prenatal Instruction Of Breast Feeding Mothers, Anita Berry

Loma Linda University Electronic Theses, Dissertations & Projects

This experimental study tested the effect of prenatal instruction on the success of a group of mothers who desired to breast feed their infants. It was hypothesized that mothers receiving information on how to nurse their infants, how to prevent complications and how to cope with common problems of breast feeding would have a higher success rate than those not so instructed.

Criteria for success was that the mothers would have an adequate supply of milk to meet the nutritional demands of their infant without supplementation, would have fewer and less severe complications, and would express a higher degree of …

The establishment of a proper diagnosis and means of communication between the oral surgeon and orthodontist are essential in achieving a good final result for the surgically treated case. Fortunately, a scientific method of diagnosis is available that can provide both specialties with a common language. Computerized cephalometric analysis can provide the diagnosis and link of communication for the discussion of goals and treatment. …


A Method Of Analyzing Mandibular Movement, Richard B. Mccoy Jun 1973

A Method Of Analyzing Mandibular Movement, Richard B. Mccoy

Loma Linda University Electronic Theses, Dissertations & Projects

Mandibular movement is considered to be a fundamental factor in the study, analysis, and treatment of occlusion. For many years, dentists have realized that dental health depends upon the compatibility of mandibular movements and occlusion. This realization has led to the development of new methods and techniques for recording accurately and scientifically the movements of the mandible. In order for this data to be of scientific value, it must be stored in a usable form which is easily available for analysis.

The purpose of this research project was to develop a procedure for storing and recalling mandibular-movement information. Before such …

Role Of Membrane-Associated Components Of Mycoplasma Arthritidis On The Biosynthesis Of Humoral Antibodies And Arthritogenic Properties In Experimental Animals, Lois M. Bergquist

Loma Linda University Electronic Theses, Dissertations & Projects

The virulence of animal-passaged Mycoplasma arthritidis (158) was demonstrated to be enhanced in rats by growth in oleic acid-enriched broth. The virulence of a laboratory-maintained culture of the same strain was unaffected by similar growth conditions. No differences either in the immune response as measured by complement-fixing (CF) antibodies or in the histogenesis of the disease were detected when rats were injected with animal-passaged M. arthritidis grown either in the presence or in the absence of oleic acid. All tests for metabolism-inhibiting (MI) antibodies in the rat were negative.

A Mycoplasma-associated immunosuppression of the primary and of the secondary hemagglutinin …
