Localization Of A Radiolabeled Monoclonal Antibody To Calcitonin In Rat Medullary Thyroid Carcinoma Allografts, Naguib A. Samaan, Kuo-Pao Yang

Henry Ford Hospital Medical Journal

A radiolabeled anticalcitonin monoclonal antibody (MoAb) was testedfor tumor-localizing capability in WAG/Rij rats allografted with cultured medullary thyroid carcinoma cells (line 44-2). 131I-labeled anticalcitonin IgG was taken up by the tumors in a time-dependent and dose-dependent manner. Tumor tissue uptake of the injected MoAb was 0.7 to 1.3%/g of tumor tissue when tested with a dose range of 40 lo 250 μg/kg of body weight. Distribution ratios of the radiolabeled MoAb were 1.2:1 for tumor-to-blood and 2-20:1 for tumor-to-organs. In rats injected with control IgG, disiribution ratios of radioactivity were 0.4:1 for tumor-to-blood, and 0.6-2:1 for tumor-to-organs. These results suggested …

Application Of Minisatellite Dna Probes To Linkage In Men-2, Bruce A. J. Ponder, Alec J. Jeffreys, Nicola E. Hartley, Clare Carter, Douglas F. Easton, Hakan Telenius, Margareta Telenius-Berg

Henry Ford Hospital Medical Journal

We describe the potential benefits and the limitations of the use of highly polymorphic minisatellite DNA probes for genetic linkage analysis of multiple endocrine neoplasia type 2A (MEN-2 A). The advantage of these probes is that up to 34 loci can be examined in a single experiment, and since the loci are highly polymorphic, almost every individual in every family is informative. The disadvantage is that the DNA fragment lengths of the alleles at any given locus differ from one family to another, so that families cannot be combined, and large single sibships are needed to obtain significant linkage data. …

One Large Kindred Excludes A Locus For Multiple Endocrine Neoplasia Type 2a From About 25% Of The Human Autosomal Genetic Map, Andrew J. Pakstis, Judith R. Kidd, Carmela M. Castiglione, Beth A. Pletcher, Patricia D. Murphy, Lindsay A. Farrer, Myron Genel, Kenneth K. Kidd

Henry Ford Hospital Medical Journal

This report presents pairwise linkage results from our search for the locus of the gene (MEN2A) for the multiple endocrine neoplasia type 2A (MEN-2A) syndrome in one large kindred (the N kindred), clearly segregating for an autosomal dominant form. About 25% of the autosomal genome is excluded when these new results are combined with those we have published previously. The genetic markers employed are distributed across at least 19 of the 22 autosomes. Seven genetic markers whose chromosomal locations are not yet established have also been studied.

Henry Ford Hospital Medical Journal

Linkage analyses were carried out in nine Japanese kindreds with multiple endocrine neoplasia type 2A (MEN-2A) using polymorphic classical markers and DNA markers. We excluded close linkage of the MEN-2A gene (MEN2A) locus with Gm, JK, PGMl, and a DNA segment, D20S5, which is assigned to band 12 of the short arm of chromosome 20 (20p12.2). Assuming that MEN2A is recessive at the cellular level as in retinoblastoma (RB) and Wilms' tumor (WT). comparison of constitutional and tumor genotypes may be useful in the search for the MEN2A locus. When DNA samples from 12 patients with medullary thyroid carcinoma (MTC) …

Where Is The Locus For Multiple Endocrine Neoplasia Type 2a?, Nancy E. Simpson, Kenneth K. Kidd

Henry Ford Hospital Medical Journal

Attempts to map the locus of the gene (MEN2A) for the multiple endocrine neoplasia type 2A (MEN-2A) syndrome over the past II years are reviewed. Lod scores from family linkage studies of polymorphisms for 26 proteins and 64 DNA markers (restriction fragment length polymorphisms or RFLPs) were pooled from the published literature and the authors' unpublished data. The pooled data excluded 32% of the genome as possible sites for the MEN2A locus. This represents a considerable increase in the area of exclusion over that of the 6% reported at the first workshop. Linkage studies of RFLPs recognized by DNA sequences …

Different Mechanisms Of Calcitonin, Calcitonin Gene-Related Peptide, And Somatostatin Regulation By Glucocorticoids In A Cell Culture Of Human Medullary Thyroid Carcinoma, Gilbert J. Cote, Robert F. Gagel

Henry Ford Hospital Medical Journal

We have employed the TT cell line, a model for the human medullary thyroid carcinoma cell, lo study the regulation of peptide hormone production by glucocorticoids. Complementary DNA probes were used to measure the calcitonin (CT), CT gene-related peptide (CGRP), and somatostatin (SRIF) mRNA levels. Dose-response experiments in serum-free medium showed that dexamethasone (six-day treatment) lowered somatostatin (to 1% of basal) and CGRP mRNA (to 50% of basal) and stimulated CT mRNA (threefold to thirteenfold) with a half-maximal effective concentration of 10⁻⁸ M. Time course studies for cells continuously exposed to 10⁻⁶ M dexamethasone showed a rapid (within …

The Determination Of Antibody Levels In Endodontic Patients Against Eleven Microorganisms Using Ifa And Elisa Techniques, William C. Payne

Loma Linda University Electronic Theses, Dissertations & Projects

Endodontic (root canal) infections are generally considered to be caused by the invasion of microorganisms which destroy pulp tissue and extend to the periapical region. No definitive study has identified a specific bacterium or group of bacteria as etiological agents. We quantitively measured antibodies present in the serum of 30 normal individuals and patients with either chronic (n = 30) or acute (n = 30) periapical lesions with the indirect fluorescent antibody (IFA) and enzyme-linked immunosorbent assay (ELISA) for IgG and IgM against 11 oral microorganisms routinely isolated from such lesions. The results were analyzed statistically. Analysis of variance of …

A Non-Human Primate Model For Studying Corticotomy-Facilitated Orthodontic Tooth Movement, R. David Rynearson

Loma Linda University Electronic Theses, Dissertations & Projects

This study was undertaken to test the hypothesis that a corticotomised tooth moves as a tooth-bone unit when under orthodontic force. A non-human primate model was designed to test the hypothesis. The non-human primate selected was Macaca fasicularis. Three adult males with erupted third molars were chosen so that extrapolation could be made to the adult human. The methods employed included the following: 1) Each animal had one treatment quadrant and one control quadrant per arch; 2) Pre-op and post-op study models were made; 3) All 2nd premolars, 2nd molars, and 3rd molars were banded; 4) A full-thickness flap …

Quantitation Of Teratogenic Effects Of 5-Fluorouracil Administered To Mice In Vivo Or In Submerged Limb Culture, Theresa A. Sanders

Electronic Theses and Dissertations

This study demonstrates the use of submerged limb culture in teratologic testing. Pregnant mice were treated on day 11 of gestation (E11, plug date = E0) with 10, 20 or 40 mg of 5-fluorouracil (FU) per kg body weight. On E17, treated and untreated fetuses were examined for gross malformations and were fixed in 95% ethanol. Reduction of limb size and digital defects, including ectrodactyly (ED), syndactyly (SD), microdactyly and polydactyly were dose-dependent. In parallel studies, pregnant mice were treated on the morning of E11 and embryos were removed either 7h (E11) or 24h (E12) later for submerged limb culture. …

Comparative Study Of Elongated Chromosomes In Sheep And Goats And A Proposed Standard, Stephen H. Mensher

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A cell synchronization technique was used that consistently yielded numerous elongated chromosomes, which are necessary for producing high-resolution G-banding. The prometaphase stage of contraction was determined to have the greatest utility for detailed comparative analysis and, therefore, was used in the preparation of the proposed standard high-resolution karyotypes and idiogram.

A proposed standard high-resolution G-band karyotype of the domestic sheep and goat is presented, along with a high-resolution G-band idiogram of the goat. The karyotypes presented contain considerably more bands than contemporary karyotypes and provide much greater resolution for linear differentiation. The X chromosome of the sheep is acrocentric, rather …

Histologic Host Response To Polyoxymethylene Prosthesis As A Temporomandibular Joint Condylar Replacement, Frederick R. Mathews

Loma Linda University Electronic Theses, Dissertations & Projects

Polyoxyinethylene (Delrin) is a polyacetyl homopolymer which has been used successfully in many orthopedic joint replacements. To determine histologic host response to Delrin as a temporomandibular joint condylar replacement condyles were removed from ten fully mature macaca fasicularis monkeys. The condyles were replaced with a total prosthetic Delrin condyle attached to a titanium mesh. Specimens obtained at one, two, and six months indicated total acceptance of the Delrin, remodeling of the glenoid fossa and formation of bone between the middle cranial fossa and the roof of the glenoid fossa. These findings would indicate Delrin is a viable option for condylar …

Adaptation Of Striped Bass To Sea Water Following Direct Transfer From Freshwater: Morphological, Biochemical, And Physiological Parameters, Judy A. King

Electronic Theses and Dissertations

There has been heightened interest in the biology of striped bass (Morone saxatilis) because of increased pollution in their native spawning grounds and because of their extensive use in landlocked sport fisheries. Their euryhalinity makes them an excellent species for osmoregulation studies. The objective of this research was to study the rate of adaptation of striped bass gills to sea water (3% salt) after direct transfer from freshwater using biochemical (ion transport enzyme levels), physiological (chloride efflux), and ultrastructural methods. Striped bass have specialized osmoregulatory cells located on the interlamellar and afferent surfaces of their gill filaments as shown by …

T-Lymphocyte Subset Studies To Monitor Patients With Aids And Aids-Related Complex, Hajime Hayashi, Eugene Mezger, Michael J. Deegan, Evelyn J. Fisher, Norman Markowitz

Henry Ford Hospital Medical Journal

Multiple specimens from 124 patients from our clinic were evaluated for T4/T8 cell ratio over three to 28 months. Twenty-nine of 30 patients with the acquired immunodeficiency syndrome (AIDS), 58 of 71 patients with AIDS-related complex (ARC), and four of 23 patients at risk showed initial T4/T8 cell ratios of less than 0.8. which either remained unchanged or decreased. Seventeen of 23 AIDS patients and two of 20 ARC patients with a consistently low ratio (0.3 or less) died during the follow-up period. This indicated that the severity of disease could be predicted by periodical T4/T8 cell ratio studies. These …

Gastrointestinal Complications Of Aids: Radiologic Findings, Marc A. Bernstein, Jeremy J. Hollerman, Peter J. Feczko

Henry Ford Hospital Medical Journal

The acquired immunodeficiency syndrome (AIDS) is a significant health problem. Patients with this disease develop unusual infections and neoplasms, many within the gastrointestinal tract. Of the 66 AIDS patients seen over a three-year period at Henry Ford Hospital, 25 patients had AIDS-related gastrointestinal disease, with one death attributed to this cause. The radiologic findings and pathologic correlation of this experience are presented.

Renal Involvement In The Acquired Immunodeficiency Syndrome: Presentation, Clinical Course, And Therapy, Robert Provenzano, Warren Kupin, Godofredo C. Santiago

Henry Ford Hospital Medical Journal

Acute renal failure developing during the clinical course of the acquired immunodeficiency syndrome (AIDS) has been related to complications of sepsis, nephrotoxic antibiotics, and recently to the development of glomerular lesions. Of 114 AIDS patients admitted to our hospital between January 1985 and June 1986. II patients (9.6%) developed acute renal failure. None of these II patients had a history of intravenous drug abuse or hypertension. All patients were male with an average age of 35 years old, 81% were black, and all were bisexual or homosexual. Renal failure was attributed to AIDS-related focal glomerulosclerosis (five cases), prerenal azotemia (one …

Bilateral Anterior Cerebral Artery Occlusion In An Alcohol Abuser With Sickle-Cell Trait, Thomas H. Swanson, John L. Zinkel, Patti L. Peterson

Henry Ford Hospital Medical Journal

The contribution of ethanol ingestion to brain infarction is unclear, although many studies suggest that the two may be causally related. We report an unusual case of bilateral anterior cerebral artery occlusion in a young female ethanol abuser with sickle-cell trait whose platelets showed hyperaggregability during epinephrine and adenosine diphosphate-induced aggregation experiments. It is concluded that ethanol withdrawal and dehydration along with direct effects of ethanol on platelet aggregation may result in cerebral artery thrombosis. Sickling of red blood cells in the distal circulation also may be a compounding factor, but this is not proven.
