Play Preparation For The Adeno-Tonsillectomy Patient, Carol Brown, Harriet Hecker

Loma Linda University Electronic Theses, Dissertations & Projects

Hospitalization and surgery have been recognized as being psychologically stressful for the majority of children. Hospital personnel have attempted to reduce some of the unnecessary psychological stress incurred by children by the use of many different methods. This study attempted to evaluate the use of preoperative play preparation sessions for minimizing this stress. The method was experimental with one variable. The subjects were forty-one children aged three and one-half to seven and one-half who had adeno-tonsillectomies. Twenty-one children comprising Group E were involved in a play session by the researchers. Twenty children were not prepared in this way. The tools …

A Study In The Comparison Of Ocular And Extremity Dominance Among A Stuttering And Non-Stuttering School-Age Population, Bruce Frank Brantingham

Loma Linda University Electronic Theses, Dissertations & Projects

The nul-hypothesis has been confirmed by the analysis of the study, in that they show no relationship between stuttering and unilateral dominance. The results indicate that the laterality measure of the experimental group did not differ significantly from that of the control group.

In as much as the results of only one statistical test were significant, it is felt that this does not detract from the contribution of the study. It would seem that the results obtained from this comparison, the analysis of overall visual adequacy and extremity dominance, could have occurred by chance alone. It is pointed out, however, …

An Instructional Method For Self-Administered Medications, Beryl Marx, Lorene Russell

Loma Linda University Electronic Theses, Dissertations & Projects

An experimental study was done to determine the effectiveness of an instructional method for older ambulatory patients taking prescribed self-administered medications. This method was developed to emphasize the physicians' specific orders, the purpose of medications, feedback of instruction and a plan for remembering and recording medications. The hypothesis tested was that a selected group of ambulatory patients age 60 and over with the instructional method would make significantly fewer errors than a similar control group with no instructions.

Sixty private patients from the Loma Linda University Hospital outpatient department were selected and randomly placed in the experimental and control groups. …

The Transfer Of Hydrogen In The Reduction Of Progesterone, William H. Kersey

Loma Linda University Electronic Theses, Dissertations & Projects

Experimental female rats were given daily injections of synthetic estrogens for six months. The effect on rat ovarian 20α-OH-SDH was not definitive. Diethylstilbestrol and 17α-ethynylestradiol caused a significant drop in activity as compared with controls while mestranol caused a slight increase in activity. A synthetic progestin, medroxyprogesterone, had no apparent effect on the activity of the enzyme.

Rat ovarian 20α-OH-SDH was purified fivefold by ammonium sulfate fractionation and chromatography on DEAE-cellulose.

The homogeneity of the enzyme was checked by means of disc gel electrophoresis. At pH 8.2 no significant contamination appeared in the electrophoretic pattern, but at pH 9.0 five …

Masseter Muscle Position Relative To Skeletal Open Bite And Skeletal Closed Bite, Alonzo David Proctor

Loma Linda University Electronic Theses, Dissertations & Projects

Modification of cephalometric roentgenographic procedures provided a means to identify the anterior borders of the right and left masseter muscles and relate them to surrounding dentoskeletal elements. Attachment of short, stiff, wires to the cheeks in a position superficial to the anterior borders of the muscles, subsequent to palpation and prior to exposure of the roentgenographic film, was the procedure used. The bi-lateral images projected on the film were averaged and traced along with dentoskeletal elements including those associated with skeletal type. This line representing the anterior border of the musculature was used to assess muscle position in the vertical …

Some Aspects Of Carbohydrate Metabolism In The Cercariae Of Schistosoma Mansoni Sambon, 1907, A. Eugene Dunham Jr.

Loma Linda University Electronic Theses, Dissertations & Projects

Cercariac of Schistosoma mansoni were studied for glycogen utilization, uptake of glucose from solution, lactic acid production, and respiration.

Using the anthrone method of determination of carbohydrate, the amount of glycogen used by a single cercaria in 4 hours is determined as 43.2 x 10^-4 μg ± 6.6 x 10^-4 μg.

Glucose was not observed to have been used from solution under the conditions of the experiment, even in the presence of trehalose. The determinations were made by the Glucostat method.

After deproteinization and desugarization, aliquots of supernatant from cercarial suspensions were analyzed for lactic acid using p-phenylphenol …

The Relationship Of Abdominal Breathing And Relaxation During Labor, Loann Mac Dougall, Judith Miller

Loma Linda University Electronic Theses, Dissertations & Projects

A causal-comparative, study was done in a university hospital using twelve subjects to determine if the "unprepared" patient could learn and carry out abdominal breathing during contractions. It was hypothesized that the "unprepared" patient in early labor could be taught and could carry out deep slow abdominal breathing during uterine contractions with decreased skeletal muscle tension as measured by an electromyograph.

Two tools were used for data collection, (1) a portable electro myograph to obtain an objective evaluation of the effect of abdominal breathing upon skeletal muscle relaxation; and (2) a supplementary data sheet for the collection of identifying material …

The Advantages Of A Condyle-Gnathion Reference Line In Roentgenographic Cephalometry, Ernest N. Chan

Loma Linda University Electronic Theses, Dissertations & Projects

Evaluation of the cephalograms of 150 patients showed a wide range in the angulation of the lower border of the mandible to the various facial planes. The degree of this angulation did not always correspond with the severity of malocclusion. Group I represents normal occlusions, Group II comprises malocclusions.

A new reference line is submitted for the investigation of its advantages in cephalometric roentgenography. The mandibular radius drawn through the geometric center of the condyle to the point gnathion is correlated with several indices of facial growth, namely (1) ANB difference, (2) upper facial:lower facial height and (3) PoNB distance …

The Development Of An Instrument For Three Dimensional Analysis Of Micron Quantities Of Tooth Movement, M. Clark Lamberton

Loma Linda University Electronic Theses, Dissertations & Projects

In order to quantitate initial tooth movement in response to forces applied to the tooth crown, an instrument for intraoral use has been developed. The photomicrometer consists of nine photosensitive cells mounted in an assembly of two layers. Eight of the cells were mounted to form X and Y axes, top layer and bottom layer, to measure horizontal movements. The ninth cell was mounted in the center of the bottom layer and was used for alignment and for measurements in the Z or vertical axis. The photocell assembly was approximately 10 mm diameter and 6 mm high. This assembly when …
