The Effect Of An Anti-Osteoclastic Agent And A Collagen Sponge On Root Resorption Following Regenerative Periodontal Surgery In The Dog, Rudolf Hahn Aug 1989

The Effect Of An Anti-Osteoclastic Agent And A Collagen Sponge On Root Resorption Following Regenerative Periodontal Surgery In The Dog, Rudolf Hahn

Loma Linda University Electronic Theses, Dissertations & Projects

Previous studies indicate that root resorption is a frequent sequela to significant amounts of periodontal repair following experimental regenerative periodontal surgical procedures in animal models. To study if root resorption can be reduced or prevented, periodontal repair was evaluated in large horizontal circumferential defects in the dog in the absence of influence from the oral environment. Diphosphonate (Cl2 MDP) applied topically to the root surfaces prior to wound closure as well as the use of a collagen sponge membrane (Helistat®) draped over the root surfaces and a control with no additional treatment after defect creation were the modalities employed. …


Effect Of Photoperiod On Developmental Morphology And Enolase Isoenzyme Immunohistochemistry In Rat And Djungarian Hamster Superficial Pineal Glands, Chalmer D. Mcclure Aug 1989

Effect Of Photoperiod On Developmental Morphology And Enolase Isoenzyme Immunohistochemistry In Rat And Djungarian Hamster Superficial Pineal Glands, Chalmer D. Mcclure

Loma Linda University Electronic Theses, Dissertations & Projects

The best understood functional activity of the pineal gland is its diurnal production of melatonin in response to environmental lighting cues. Several enzymes of the melatonin pathway respond to daily photoperiod changes, for example hydroxyindole-O-methyltransferase (HIOMT) and serotonin N-acetyltransferase (SNAT). Increased levels of the glycolytic enzyme neuron-specific enolase (NSE) are thought to reflect increased physiological demands placed on neurons and neuroendocrine tissues. Homodimer non-neuronal enolase isoenzyme (NNE) is immunolocalized to cells, and the hybrid enolase (consisting of subunits from NSE and NNE) has been seen in cerebellar stellate and basket cells. Although not rate limiting, concentrations of both NSE and …

Transforming Growth Factor-Beta Stimulation Of Lung Fibroblast Prostaglandin E2 Production., Arturo Diaz, John Varga, Sergio A. Jimenez Jul 1989

Transforming Growth Factor-Beta Stimulation Of Lung Fibroblast Prostaglandin E2 Production., Arturo Diaz, John Varga, Sergio A. Jimenez

Department of Medicine Faculty Papers

Transforming growth factor-beta (TGF beta) stimulated the production of total protein, collagen, and fibronectin by normal human lung fibroblasts. The stimulatory response was maximal at 100 pM TGF beta and reversed toward control at higher concentrations. Inhibition of fibroblast prostaglandin (PG) synthesis enhanced TGF beta-induced stimulation of total protein, collagen, and fibronectin production and reversed the negative slope of the dose-response curve at high concentrations of TGF beta. Determination of the steady-state levels of Types I and III procollagens and fibronectin mRNAs employing specific cDNA probes demonstrated that inhibition of fibroblast PG production increased the stimulatory effect of TGF beta …

Guanine Nucleotide-Binding Protein, Alpha I-3, Directly Activates A Cation Channel In Rat Renal Inner Medullary Collecting Duct Cells., Douglas B. Light, Dennis A. Ausiello, Bruce A. Stanton Jul 1989

Guanine Nucleotide-Binding Protein, Alpha I-3, Directly Activates A Cation Channel In Rat Renal Inner Medullary Collecting Duct Cells., Douglas B. Light, Dennis A. Ausiello, Bruce A. Stanton

Dartmouth Scholarship

We examined whether GTP binding proteins (G proteins) regulate sodium conducting channels in the apical membrane of renal inner medullary collecting duct (IMCD) cells and thereby modulate sodium absorption. Patch clamp studies were conducted on inside-out patches of the apical membrane of IMCD cells grown in primary culture. Guanosine 5'-triphosphate (GTP) and the nonhydrolyzable GTP analogue, GTP gamma S, which activate G proteins, increased the open probability of the cation channel. In contrast, the nonhydrolyzable GDP analogue, GDP beta S, which decreases G protein activity, inhibited the channel. Pertussis toxin also reduced the open probability of the channel. Addition of …


The Composition And Concentrations Of Cyanobacteria In The North Landing River, Virginia And Upper Currituck Sound, North Carolina, Sonja E. Midgette Jul 1989

The Composition And Concentrations Of Cyanobacteria In The North Landing River, Virginia And Upper Currituck Sound, North Carolina, Sonja E. Midgette

Biological Sciences Theses & Dissertations

A 12 month study of cyanobacteria composition and concentrations in the North Landing River and upper Currituck Sound was conducted from March 1986 to February 1987. Epifluorescence microscopy and the fluorochrome proflavin were used to determine cell concentrations and vertical, station to station and seasonal distribution of these cells. Cyanobacterial assemblage patterns were coupled with pH, temperature, salinity and water transparency readings.

Cyanobacteria were found to be a persistent and prolific phytoplankton component of both the river and upper sound. For a comparison of vertical distribution for each station, an analysis of variance for. two groups of equal size was …

Ulceroglandular Tularemia: A Typical Case Of Relapse, Stanley D. Miller, Michael B. Snyder, Michael Kleerekoper, Colby H. Grossman Jun 1989

Ulceroglandular Tularemia: A Typical Case Of Relapse, Stanley D. Miller, Michael B. Snyder, Michael Kleerekoper, Colby H. Grossman

Henry Ford Hospital Medical Journal

Tularemia is an infectious disease that continues to occur sporadically and in epidemics in the United States. It is characterized as an acute febrile illness with constitutional symptoms associated with skin, glandular, respiratory, or gastrointestinal involvement. Tularemia usually can be treated effectively with streptomycin. Relapse most often occurs when patients are treated with bacteriostatic agents such as chloramphenicol or tetracycline. We present a case of ulceroglandular tularemia distinguished by its relapse after initial streptomycin/doxycycline therapy and subsequent slow response to additional streptomycin.


Orf: A Case Report, Brent W. Mohr, David Katz Jun 1989

Orf: A Case Report, Brent W. Mohr, David Katz

Henry Ford Hospital Medical Journal

Ecthyma contagiosum (orf), a viral disease endemic to sheep and goats, can be zoonotically transmitted to humans through contact with infected animals. While the disease is common among sheep and goat herders worldwide, it comes to medical attention infrequently since it is generally a mild self-limited illness. We recently treated a healthy 36-year-old female who presented with bullous lesions on her fingers and a diffuse macular rash which had developed after antibiotic therapy for her bullae. She had been caring for her neighbor's goats which had recently been ill with "sore mouth." We discuss this case of orf and review …


In Vitro Evaluation Of Cancer Patient Immune Responses Following Infusion Of Radiolabeled Murine Monoclonal Antibody, Kelly A. King Jun 1989

In Vitro Evaluation Of Cancer Patient Immune Responses Following Infusion Of Radiolabeled Murine Monoclonal Antibody, Kelly A. King

Loma Linda University Electronic Theses, Dissertations & Projects

Several monoclonal antibody (MAb) types derived from mice have been developed specifically for the use of targeting human tumors. The specificity of these murine MAb’s for their respective tumor antigens is very high making them potentially good immunotherapeutic agents for cancer treatment and diagnosis. A limiting factor in using these murine MAb’s in patients is the development of human anti-mouse antibody (HAMA). The presence of HAMA may reduce the effectiveness of MAb for tumor targeting. If patient sensitization could be quickly detected following the initial infusion of MAb, then future infusion could be altered or terminated to prevent further sensitization. …


Enhancement Of Intratumor Antibody Distribution With A Bifunctional Antibody Delivery System And With Hyperthermia, Karen Lynn King Jun 1989

Enhancement Of Intratumor Antibody Distribution With A Bifunctional Antibody Delivery System And With Hyperthermia, Karen Lynn King

Loma Linda University Electronic Theses, Dissertations & Projects

The intratumor distribution of a new monoclonal antibody-hapten-based delivery system was examined. From two marine antibodies, Hybritech, Inc. has developed a bifunctional antibody (BPA) with specificities against CEA (ZCE-025 or GEM 231) and against one of two derivatives of [111In]-benzyl-EDTA (CHA 255), EOTUBE or BLEDTA IV, to form ZCE/CHA or CEM/CHA. BFA accumulates in CEA-expressing tissue and clears from non-antigenic tissues prior to administration of an [111In]-hapten.

Using five groups of nude mice bearing human colon tumor xenografts (T380), we evaluated different carriers of [111In]-EOTUBE to prelocalized ZCE/CHA. We administered all antibodies and haptens …


Regulation Of Epidermal Growth Factor Receptor Synthesis By Retinoic Acid And Dexamethasone, Kerby C. Oberg Jun 1989

Regulation Of Epidermal Growth Factor Receptor Synthesis By Retinoic Acid And Dexamethasone, Kerby C. Oberg

Loma Linda University Electronic Theses, Dissertations & Projects

Fetal rat lung (FRL) cells incubated in the presence of retinoic acid or dexamethasone exhibit altered 125I-epidermal growth factor (EOF) binding capacity. Retinoic acid enhances 125I-EGF binding 3-fold following 24 hours of 37° incubation. In contrast, FRL cells incubated in the presence of dexamethasone display a 2-fold reduction in 125I-EGF binding capacity. The change in binding capacity, induced by either hormone, was due to alterations in the average number of receptors per cell as determined by Scatchard analysis of 125I-EGF binding. In the absence of retinoic acid or dexamethasone, FRL cells were calculated to have approximately …


Anthropometric Parameters In Public School Students And Seventh-Day Adventist Vegetarian And Meat-Eating Students, Joan Sabaté-Casellas Jun 1989

Anthropometric Parameters In Public School Students And Seventh-Day Adventist Vegetarian And Meat-Eating Students, Joan Sabaté-Casellas

Loma Linda University Electronic Theses, Dissertations & Projects

Concerns have been expressed for the ability of some vegetarian diets to support normal growth of children. Animal protein or meat intake showed a positive relationship to attained height in children from developing countries. In this study, the relationship between meat intake/vegetarian status and physical growth was investigated in children living in California.

Height and weight were collected on 2,272 Caucasian children aged 6-18 years attending Seventh-day Adventist (SDA) or public schools who participated in a two year longitudinal study. Age-, sex-, and school-specific mean heights and weights were at or above the national reference values. Sex-specific, age-adjusted regression analysis …


Autonomic Nervous System And Cholesterol Transport, Yuan-Line Hung Jun 1989

Autonomic Nervous System And Cholesterol Transport, Yuan-Line Hung

Loma Linda University Electronic Theses, Dissertations & Projects

The effect of autonomic nervous system on cholesterol transport is of clinical interest because the relationship between lipoprotein metabolism and atherogenesis is expressed in coronary artery disease.

Generally speaking, beta blockers increase serum VLDL level but decrease both HDL and HDL2 cholesterol levels without affecting the LDL in humans. We are unaware of reports concerning the effects of metoprolol on lipoprotein metabolism nor comparison of the effects of metoprolol and propranolol in the unhandled rat model. In part I we employed the unhandled rats to compared the effects of these 2 drugs administered with the drinking water in order …

Immunity To Larval Brugia Malayi In Balb/C Mice: Protective Immunity And Inhibition Of Larval Development., D. Abraham, R. B. Grieve, J. M. Holy, B. M. Christensen

Department of Microbiology and Immunology Faculty Papers

The objective of this study was to analyze the immune response of mice to the larval stages of Brugia malayi. Male BALB/c mice were inoculated with 3 doses of irradiated third-stage larvae (L-3) of B. malayi and were subsequently challenged with L-3 implanted ip within diffusion chambers. After 3 weeks, larvae were recovered to determine their viability, length, and stage of development. A significant reduction in parasite survival was observed in immunized mice. Furthermore, larvae recovered from immunized mice were significantly shorter than larvae recovered from control mice. All larvae recovered from immunized mice were L-3, whereas 96% of larvae …

Children Raised By Homosexual Parents: Sexual Orientation, Mental & Sexual Health, Theresa Gramlich May 1989

Children Raised By Homosexual Parents: Sexual Orientation, Mental & Sexual Health, Theresa Gramlich

Masters Theses & Specialist Projects

Sex and morals have often been factors in custody disputes. Courts have felt that giving custody of children to homosexual parents would create an environment not in the best interest of the child. Many mental health professionals argue that these decisions have been based on prejudice and homophobia. The purpose of this study was to evaluate research on the sexual orientation of children raised by homosexual parents and review data on the mental/psychosexual health of these children. These studies revealed no difference between children raised by gay/lesbian parents versus those raised by heterosexual parents on IQ scores, gender identity, or …

Maternal Role Perception In Mothers With 4-Month-Old And 8-Month-Old Infants, Teresa B. Crockett May 1989

Maternal Role Perception In Mothers With 4-Month-Old And 8-Month-Old Infants, Teresa B. Crockett

MSN Research Projects

The purpose of this descriptive study was to assess maternal role perceptions and to determine if infant developmental tasks impact upon maternal perception. The researcher asked the following questions: Is maternal role perception more positive when the infant is 4 months of age than when the infant is 8 months of age? How does the infant's developmental task of the "social smile" at 4 m o n t h s affect maternal role perception? How does the infant's developmental tasks of "stranger reaction" and "separation anxiety" at 8 months affect maternal role perception? Barnard's Parent-Child Interaction Model (1979) and Mercer's …


Regeneration Of Meissner Corpuscles In Diabetic Mice Following Median Nerve Crush, Bonnie J. Forrester May 1989

Regeneration Of Meissner Corpuscles In Diabetic Mice Following Median Nerve Crush, Bonnie J. Forrester

Loma Linda University Electronic Theses, Dissertations & Projects

The hyperglycemic metabolic condition found in diabetes mellitus leads to the development of sensory neuropathies and causes delayed and incomplete neuronal regeneration. Diabetic sensory neuropathy has been shown to contribute to the impairment of light touch and low frequency vibratory perception. It is proposed that the regeneration of receptors that detect these sensations will be delayed and incomplete in diabetic animals with uncontrolled hyperglycemia. This study addresses the effects of diabetes on the regeneration of Meissner corpuscles, distal sensory endings that perceive light touch and low frequency vibration.

Corpuscles from 60 diabetic mice, and their age-matched, non-diabetic littermates, were examined …

Winter Habitats And Foods Of Blue Grouse In The Sheeprock Mountains, Utah, Peter J. Perkins, Frederick G. Lindzey, Jay A. Roberson, Gregory Mcdaniel, Randy Berger Apr 1989

Winter Habitats And Foods Of Blue Grouse In The Sheeprock Mountains, Utah, Peter J. Perkins, Frederick G. Lindzey, Jay A. Roberson, Gregory Mcdaniel, Randy Berger

Great Basin Naturalist

Winter habitat use and food habits of Blue Grouse (Dendragapus obscurus) were studied in an isolated Utah desert mountain range that contained little typical Douglas-fir (Pseudotsuga menziesii) winter habitat. Habitat use was concentrated in the Douglas-fir and pinyon (Pinus edulis)–juniper (Juniperus spp.) habitat. Douglas-fir and pinyon pine were the most consumed foods. Other foods that represented >15% of the composition of an individual fecal sample were limber pine (Pinus flexilis), mahogany (Cercocarpus ledifoliu), juniper, and an Anteunaria–Cirsium type. The breadth in winter diet indicates that Blue Grouse may …


Arousal And Physiological Toughness: Implications For Mental And Physical Health, Richard A. Dienstbier Apr 1989

Arousal And Physiological Toughness: Implications For Mental And Physical Health, Richard A. Dienstbier

Department of Psychology: Faculty Publications

From W. B. Cannon’s identification of adrenaline with “fight or flight” to modern views of stress, negative views of peripheral physiological arousal predominate. Sympathetic nervous system (SNS) arousal is associated with anxiety, neuroticism, the Type A personality, cardiovascular disease, and immune system suppression; illness susceptibility is associated with life events requiring adjustments. “Stress control” has become almost synonymous with arousal reduction. A contrary positive view of peripheral arousal follows from studies of subjects exposed to intermittent stressors. Such exposure leads to low SNS arousal base rates, but to strong and responsive challenge- or stress-induced SNS-adrenal-medullary arousal, with resistance to brain …
