Effects Of Dietary Factors And Morphine Administration On Voluntary Alcohol Consumption And Dopamine Metabolism In Rats, Claudia Smithson

Loma Linda University Electronic Theses, Dissertations & Projects

The effect of diet and dietary additives on voluntary alcohol consumption in male Sprague-Dawley rats was studied. Alcohol intake measured weekly and reported as ml of a 10% solution ingested per 100 grams body weight. A four week pre-experimental period was designed to determine individual tendencies to drink and thus to eliminate the high and low drinkers from the study. No difference was found in alcohol intake with either starch or sugar as the carbohydrate source; however, there was a greater weight gain ( p < .025) in those animals consuming sugar-based diets. Rats on poor-quality diets containing minimal amounts of vitamins and minerals continued to gradually increase alcohol consumption during the study. This diet, supplemented with coffee, caused the greatest significant increase in alcohol intake and the lowest weight gains. Addition of coffee to the diets significantly increased alcohol consumption (p< .005) but decreased growth rate (p < .0005) . However, when the poor quality diets were supplemented with vitamins and minerals, alcohol consumption was reduced by about 50% (p < .005) and weight gain was significantly increased (p < .0005).

The daily intraperitoneal administration of morphine sulfate significantly decreased alcohol intake (p < .02) and the per cent of total fluid consumed as alcohol (p < .02) but did not effect water consumption.

An attempt was …

Studies Related To The Structure And Mechanism Of Action Of Rabbit Muscle Aldolase, Christian F. Midelfort

Dissertations (1934 -)

This dissertation deals with several aspects of the structure and catalytic functions of the enzyme fructose - 1,6-diphosphate aldolase (I.U.B. Number 4.1.2.13) isolated from rabbit muscle.

First, it concerns the chemical nature of the proteolytic modifications of aldolase by a-chymotrypsin and subtilopeptidase B (Novo) in producing an enzyme with catalytic properties like those of the aldolase modified by carboxypeptidase A. The a-chymotrypsin modification has been published (C.F. Midelfort and A.H. Mehler, J. Biol. Chem. 247. 3127 (1972)).

Second it presents evidence for the occurrence of a slow deamidation of an asparagine residue in muscle aldolase in vivo which results in …

The Possible Causes And Remediation Of Inverted Vision, Archie J. Beamer

All Master's Theses

The primary purpose of this investigation was to determine possible corrective methods for inverted vision. The visual problem is usually outgrown in the early teens, but these children who experience the problem tend to be classified as retarded because they cannot read. An intensive research of the literature for possible causes and corrective methods revealed inconclusive proof. However, two boys who were diagnosed to have inverted vision were given perceptual training exercises. The subjects responded to the treatment and in a short time were started on a reading readiness program. Although only two cases were found on which to experiment, …

Postmenopausal Osteoporosis: The Evolution Of Our Concepts Of Its Cause, Harold M. Frost

Henry Ford Hospital Medical Journal

Research findings in the last 20 years concerning senile and postmenopausal osteoporosis indicate that the skeletal condition associated with these diseases arises because some systemic factor acts directly upon the bone marrow tissues. There is a secondary tendency to accelerate loss of bone greater than in the normal aging process. The loss occurs only on those surfaces in physical contact with the bone marrow tissue.

Physiological Parameters During Perfusion Fixation Of The Rat Central Nervous System For Electron Microscopy, Everet W. Witzel

Loma Linda University Electronic Theses, Dissertations & Projects

In an attempt to elucidate the problem of extracellular space within the cerebral cortex of the rat, several physiological parameters were analyzed during perfusion fixation with glutaraldehyde and acrolein for electron microscopy. These parameters were electroencephalography, electromyography, electrocardiography, cerebrospinal fluid pressure, impedance of cerebral cortex, perfusion pressure, and flow rate of the perfusate.

The first portion of this investigation dealt with the problem of asphyxiation of tissues during fixation. A substituted blood containing fluorocarbon which was oxygenated served as the means to study this problem. The last portion of this investigation dealt with buffers and molecular size in relationship to …

Microscopic Evaluation Of Topically Applied Chlorhexidine Gluconate On Gingival Wound Healing In Dogs, Robert C. Hirst

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to evaluate microscopically the effect of topically applied 2% chlorhexidine gluconate on the healing of gingival wounds in dogs.

One week after the teeth were scaled and polished, seven experimental wound sites were prepared in the facial gingiva adjacent to the four premolars on each side of the maxillary arch in six young Labrador dogs. From this point the dogs were fed a soft plaque-inducing diet. Chlorhexidine solution was applied daily to either the right or left maxillary premolars while on the opposite side of the arch in three dogs the first and second …

Patients' Reactions To Witnessing Cardio-Pulmonary Resuscitation, Lynn Andree Finch

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to describe the reactions to stress in patients witnessing a cardio-pulmonary resuscitation, in order to determine if the witnessing patients' needs are being met adequately, and to determine the effect of a specific psychological stressor on patients.

All resuscitations ("STATS") done over a two-month period at Loma Linda University Medical Center, with oriented patients in the room, were observed and recorded on an Observation Guide. A Questionnaire was also solicited from medical-surgical nursing personnel who had observed "STATS" with witnessing patients in the last three months. The Guide and the Questionnaire were developed from …

Marrow Isografts In The Oral Cavity Of Mice, Robert L. Merin

Loma Linda University Electronic Theses, Dissertations & Projects

The objectives of this study were to develop an animal model for testing oral bone and marrow transplantation that is adaptable to immunological studies; to determine the effect of an isogeneic graft of cancellous bone and marrow on the healing of surgically created defects; and to determine the fate of grafted isogeneic cancellous bone and marrow transplanted into defects. Fourteen CBA/H mice served as experimental animals and bilateral intraoral defects were prepared. The experimental side received isogeneic graft material while the other side served as a control. Osseous healing was found to be accelerated in the defects receiving graft material …

The Effect Of Oral Allografts Of Cancellous Bone And Marrow In Mice, George E. Deeb

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was: to develop a model for testing oral bone transplantation; to study the healing of a surgically produced defect with and without the transplantation of strongly allogeneic cancellous bones and marrow; and to determine the fate of the allogenic grafts. Twenty-eight CBA/H mice served as experimental animals. Intra-oral defects were made and in 14 of the animals strongly allogenic cancellous bone and marrow were transplanted. The 14 remaining animals served as controls. It was observed that the healing was delayed in the experimental animals as compared to the controls and that the grafted material was …

The Hyobranchium And Throat Myology Of The Adult Ambystomidae Of The United States And Northern Mexico, John E. Krogh, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

The 16 species and subspecies of the Ambystomidae of the United States are placed into six groups according to their throat morphology as follows: The Dicamptodon group, the Rhyacotriton group, the A. Annulatum–A. cingulatum group, the A. gracile-A. jeffersonianum-A. mabeei-A. macrodactylum-A. maculatum group, the A. talpoideum group, the A. opacum-A. texanum group, and the A. rosaceum-A. t. tigrinum-A. t. melanostictum-A. t. nebulosum group. Dicamptodon appears to be the most primitive group and Rhyacotriton the most specialized. Based on the morphology of the throat region it is suggested that A. rosaceum be placed in the tiger salamander group as a subspecies …

Value Of Oxygen With Innovar And Methohexital For Outpatient Oral Surgery, Andrew D. Harsany

Loma Linda University Electronic Theses, Dissertations & Projects

This paper demonstrates the value of oxygen in maintaining arterial blood gas in an adequate range during outpatient oral surgery. Dental extractions were completed on ten patients under an anesthetic technique utilizing Innovar and methohexital with supplemental nasal oxygen. Blood gas samples were drawn at five stages during the procedure.

The mean of the PaO₂ samples drawn with the patient at the point of deepest sedation was approximately three times the normal value.

Oxygen for pulmonary ventilation provides a reservoir in the lungs, saturation of hemoglobin, and increased oxygen in the plasma which provides a margin of safety if …

Nitrogen Movement Under Irrigated Corn As Influenced By Nitrogen Source And Rate, Douglas C. Muir

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to determine nitrogen movements under a fall applied fertilizer as affected by rate of application of fertilizer, type of fertilizer carrier, and by crop grown. Two nitrogen fertilizers, calcium nitrate and ammonium sulfate, were applied in the fall of 1970. The soil profile was sampled in the spring of 1971 and again in the fall of 1971. Nitrate-nitrogen from both the calcium nitrate and the ammonium sulfate applications was found to have moved significantly from the time of application to the time of spring soil sampling. Two effects from the high rate of both …

Nutrients And Phytoplankton In Hyrum Lake, Robert Bruce Murray

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The current investigation indicates that the routine appearance of a noxious blue-green algal bloom of Aphanizomenon flos-aquae, in Hyrum Lake, a reservoir in northern Utah is a result of excess phosphorus. Data indicate that the algal growth is initiated by phosphorus liberated from the phosphorus rich bottom sediments, and at a time when nitrogen is present in excess in the lake relative to phosphorus.

Results indicate that the Little Bear River is the major source of nitrogen and phosphorus contributing to the eutrophication of Hyrum Lake. Nitrogen and phosphorus fluctuations in the Little Bear River proved to be concurrent with …

Understory Characteristics Related To Site Quality For Aspen In Utah, James H. Warner, Kimball T. Harper

Brigham Young University Science Bulletin, Biological Series

An analysis has been made of the basic ecology of aspen forests of the mountainous areas of Utah and northern Arizona. Forty-nine study areas have been examined in respect to density, height and age of the tree cover, tree reproduction, and composition and biomass production of the understory. A graphic model of interspecific assocations among prevalent understory species has been prepared by a cluster-analysis procedure based on presence and absence of species in 1,225 small quadrats (0.25 m²) uniformly distributed among the 49 stands. The model separates species of relatively stable as opposed to rapidly seral aspen forests. …
