The Effect Of Fetal Age On Skin Permeability In Guinea Pigs, Benita Stiles Whitted

Loma Linda University Electronic Theses, Dissertations & Projects

Preliminary investigation has indicated large decreases in fetal skin permeability during the latter half of gestation (Parmley and Seeds, 1970; Treager, 1966). The purpose of this study was to demonstrate the degree of skin permeability in fetal guinea pigs at various gestational stages. The test hypothesis was that these skins would show a significant decrease in permeability to tritiated water when tested at time increments through out the latter half of gestation.

In vitro skin permeability to tritiated water was measured in samples from 22 guinea pig fetuses. Gestational age ranged from 30 to 65 days in increments of five, …

Lingual Function And Articulatory Competence, Donna E. Swenson

Loma Linda University Electronic Theses, Dissertations & Projects

Dworkin (1979) states that, of the 2.5 million children and young adults in the United States with a communication problem, 60% have a functional articulation disorder for which no psychologic or physical problem can be found. The oral mechanism examination is an established part of a speech and language examination for testing these children, and the tongue is the most important organ for speech (Johnson, Darley, and Spriestersbach, 1963). However, no conclusive rationale for the procedure or objective lingual measurements have been established. This research, therefore, was designed as a pilot study to investigate whether lingual structure and function are …

Easily Administered Recognition Of Linguistically-Handicapped Youngsters, Robin J. Webb

Loma Linda University Electronic Theses, Dissertations & Projects

This study investigates the feasibility of involving parents as evaluators using an objective screening test for their children who are 36 to 42 months of age. A more available and nonthreatening assessor is needed as physicians, dentists and other allied health professionals who are typically used to screen children for speech, language and hearing have not been effective with this age group. This is partially due to the limited contacts they have with these children and the environmental limitations for eliciting an adequate speech and language sample (Behrens, 1978; Webb, 197B; Hirsch, 1981).

An objective-type screening instrument has been designed …

Blood Reservoir Function Of The Fetal Guinea Pig Liver, Gregory A. Roda, Raymond D. Gilbert, Gordon G. Power

Loma Linda University Electronic Theses, Dissertations & Projects

To determine of the fetal liver functions as a blood reservoir, we measured liver blood volume under normal conditions and after hemorrhage and volume loading. Nineteen pregnant guinea pig sows and 54 near-term fetuses were injected intravenously with ⁵¹Cr-labeled red cells while the fetuses remained in utero. Ninety seconds later a 0.5-1.0 g sample of liver was garroted with a sharp wire into a tared tube with minimal blood loss. A blood sample was taken to measure counts per ml of blood, the fetus killed and the remainder of the liver weighed. Blood volume of the liver and body …

The Effect Of Self-Help Support Groups On Self Esteem And Blood Glucose In Young Insulin-Dependent Diabetics, Linda L. Woertz

Loma Linda University Electronic Theses, Dissertations & Projects

Successful adaptation to diabetes is probably a function of many factors: the stress involved, the rewards, the motivation of the individual, and the self concept. The more optimal the self concept the more optimal the behavior may be. By helping the patient shape a positive self concept, a base can be built for blood glucose control (Bruhn, 1977, pp. 93-97). One method of improving self concept or self esteem may be through the development of self-help support groups for diabetics.

The purpose of this study was to evaluate the effect of self-help support group intervention on the levels of self …

Healing Following Two Different Surgical Approaches To Treating Deep Periodontal Intraosseous Defects, A. Durwin H. Chamberlain

Loma Linda University Electronic Theses, Dissertations & Projects

Surgical treatment of deep periodontal pockets associated with intraosseous defects has traditionally been performed either with or without resection of the osseous defect. A non-resective approach may provide more gain of attachment while a resective approach may give better pocket reduction. The increased pocket reduction following osseous resection is probably accomplished at the expense of some attachment loss in areas involved by the surgical procedure. Previous studies have compared periodontal surgery with and without osseous resection (i.e. Rosling et al. 1976, Knowles et al. 1979 and Smith et al. 1980). However, the effect of osseous resection does not seem to …

Work Function Analysis Of Vegetarian Entree Production, Susan Maloney, Kathleen Z. Zolber

Loma Linda University Electronic Theses, Dissertations & Projects

Data on actual labor time can be utilized as an effective management tool. With labor cost representing about 50 percent of direct cost in food service, it is essential to examine how labor time is being utilized.

A continuous time study was conducted to determine the total labor time for the production of eight vegetarian entrees. The two work areas observed were the ingredient assembly area and the cooks' production area. This labor time was recorded by Work Functions to find the dis- tribution of labor time. Data from the observations were compiled using an Apple II computer system. Reports …

An Investigation Of Selected Caring Behaviors In A Hong Kong Chinese Village, Mary Jon Waldron

Loma Linda University Electronic Theses, Dissertations & Projects

The lack of scientific information regarding caring beliefs, expectations, and behaviors in the Chinese community of Hong Kong was the problem underlying this descriptive study. A knowledge of caring behaviors as they routinely occur within a culture can provide a basis for the development of professional nursing care that is meaningful for the people of that culture. The purpose of the study was to obtain the opinions of the residents of a Hong Kong Chinese village regarding current beliefs and practices relating to touch, surveillance, health counseling, and special ethnocare techniques. Representatives of twenty families were interviewed with the assistance …

Observation Of Bone Formation In The Mandibular Symphysis Following Surgical Separation And Slow Mechanical Expansion In A Baboon, Robert J. Homer

Loma Linda University Electronic Theses, Dissertations & Projects

Mechanical expansion of the maxilla, at the midline suture, is a widely accepted orthodontic procedure used to gain arch width in certain types of maxillary deficient arches.

In animal research on the mandible, techniques using surgical separation at the symphysis with immediate expansion up to 12 mm, fixation with a metal splint, and autogenous bone transplanted into the expanded area, have been reported to be successful.

To date, no experiment utilizing slow mechanical expansion of the mandible at the symphysis has been reported.

In this pilot study, the mandible of a female baboon was surgically separated A-P at the symphysis. …

A Comparison Of Two Rapid Palatal Expansion Appliances And Their Effect On Palatal Cross-Sectional Area, William D. Scott

Loma Linda University Electronic Theses, Dissertations & Projects

Two rapid palatal expansion appliances, acrylic-free and acrylic-reinforced, were compared for their effect on the cross-sectional area of the palate. Two groups, twenty-five patients in each, were selected so that they would match as closely as possible with regards to age and sex distribution. The pre-treatment and post-treatment maxillary models were duplicated, and this duplicate model was then trimmed in a specific manner to allow the cross-sectional area between the first permanent molars to be compared. The results indicate that there is no difference, at the five percent level of significance, between these two appliances. It is concluded that the …

Evaluating The Aural/Oral Skills Of Children Identified By The Slingerland Pre-Reading Screening Procedures, Sandra L. Singleton

Loma Linda University Electronic Theses, Dissertations & Projects

Research tends to confirm the concept that it is imperative to diagnose learning disorders early and start remediation immediately. Slingerland (1977) developed an assessment tool, which reportedly aids in the identification of remediational needs before a child has experienced failure. This screening device was designed to "show modality weaknesses that call for specific instruction to prevent early failare" (Slingerland, 1977). All of the subtests from the Pre-Reading Screening Procedures are cross-modality tasks because the testing of a modality, "Auditory" or "Visual", requires the use of one or two other modalities (motor or speech) to generate a response. In order to …

The Effects Of Second Molar Extractions In Conjunction With Bionator Treatment, Mohammed Toufic Jeiroudi

Loma Linda University Electronic Theses, Dissertations & Projects

The intent of this paper is to evaluate the effects of second molar extractions in conjunction with Bionator treatments. Eighteen Orthodontic patients were used in this study. All had had second molars extracted. Lateral cephalometric radiographs were traced and used to evaluate the treatment. The average age at time of extraction was 13 years, 3 months. The average treatment time was 38.3 months.

There were some orthopedic changes. The convexity decreased significantly, the condyle axis increased more than expected in normal growth. Also, the lower facial height and facial axis both became more dolichotype (open).
