Efficient Immortalization Of Luminal Epithelial Cells From Human Mammary Gland By Introduction Of Simian Virus 40 Large Tumor Antigen With A Recombinant Retrovirus, Bartek J, Bartkova J, Kyprianou N, El-Nasir Lalani, Staskova Z, Shearer M, Chang S, Taylor Papadimitriou J

Department of Pathology and Laboratory Medicine

When defined in terms of markers for normal cell lineages, most invasive breast cancer cells correspond to the phenotype of the common luminal epithelial cell found in the terminal ductal lobular units. Luminal epithelial cells cultured from milk, which have limited proliferative potential, have now been immortalized by introducing the gene encoding simian virus 40 large tumor (T) antigen. Infection with a recombinant retrovirus proved to be 50-100 times more efficient than calcium phosphate transfection, and of the 17 cell lines isolated, only 5 passed through a crisis period as characterized by cessation of growth. When characterized by immunohistochemical staining …

Chloramphenicol Therapy Of Typhoid Fever, Z A. Bhutta, S H. Naqvi, S Durrani, A Suria

Department of Paediatrics and Child Health

In a prospective study we compared two different dosage regimens of IV chloramphenicol succinate (100 mg/kg/day and 75 mg/kg/day) in children with culture proven typhoid. Trough and peak blood samples, obtained at 48 hrs, were analysed for free chloramphenicol by high pressure liquid chromatography (HPLC). Although the mean trough (8.8 +/- 7.7 versus 5.4 +/- 2.6 mcg/ml) and peak (19.9 +/- 12.2 versus 15.4 +/- 6.1 mcg/ml) chloramphenicol concentrations were comparable in both groups, a significantly wider range was found in the group receiving 100 mg/kg/day. Potentially toxic levels (greater than 30 mcg/ml) developed in two patients with liver dysfunction. …

Quantitative Respirator Fit Testing: Probed Facepiece Versus Probed Cartridge, Sonya Melissa Seward

Community & Environmental Health Theses & Dissertations

This study was performed to determine if there is a quantifiable difference between quantitative fit testing using a probed facepiece and a probed cartridge. Four subjects were tested on four different respirators. The respirators used were MSA & 3M full and half face respirator. Each subject performed each method five times per respirator. The results indicated no correlation between the two fit testing methods overall. However, a moderate correlation was found between the MSA respirators and the two methods. This study found many variables which influence fit testing. These include the type of respirator used (brand and facepiece), the probe …

Denker Rhinotomy For Inverted Papilloma Of The Nose And Paranasal Sinuses, Samuel A. Mickelson, Richard D. Nichols

Henry Ford Hospital Medical Journal

Inverted papilloma of the nose and paranasal sinuses is an unusual benign neoplasm that has the propensity for local tissue destruction and an association with malignant degeneration. The tumor represents an inverted growth of epithelium rather than outward proliferation. It most commonly arises from the lateral nasal wall with growth into the nose and paranasal sinuses and only rarely originates from the septum. Presenting symptoms are usually unilateral nasal obstruction and clear rhinorrhea. Surgical excision is the recommended treatment though the aggressiveness ofthe approach has varied. Transnasal local excision has been associated with a high recurrence rate. Lateral rhinotomy with …

Management Of Chronic Staphylococcal Osteomyelitis Of The Temporal Bone: The Use Of Hyperbaric Oxygen, Vanessa G. Schweitzer

Henry Ford Hospital Medical Journal

Hyperbaric oxygen (HBO) is an effective adjunct in the management of selected otolaryngologic problems including radiation-induced necrosis of the temporal hone, malignant external otitis, mandibular osteoradionecrosis and refractory osteomyelitis, soft tissue head and neck necrotizing fasciitis, compromised skin flaps and grafts, acute air or gas embolism, and otologic barotrauma. We describe the management of a patient with insidious Staphylococcus aureus osteomyelitis of the temporal bone by the use of HBO preoperatively and postoperatively in conjunction with surgical debridement. The possible application of angiogenic agents and tetracycline hone-labeling in combination with HBO therapy in the management of refractory neurotologic disease is …

Entry Of The Hearing Impaired Into The Health Care System, Kathleen Yaremchuk, Jonathan Schmidt, Linda Dickson

Henry Ford Hospital Medical Journal

The current system of referral of patients complaining of hearing loss usually requires a dual appointment with otolaryngology and audiology. Most of these patients have sensorineural hearing loss for which there is rarely surgical or medical treatment. This study tests the hypothesis that these patients would receive appropriate treatment and that health care dollars would be saved if an audiological assessment could identify those patients who require medical or surgical care. One hundred consecutive patients whose sole complaint was hearing loss were evaluated using audiograms and "hearing abilities questionnaires" by five audiologists using subjective and objective criteria to determine the …

Systemic Dissemination Of Pneumocystis Carinii In A Patient With Acquired Immunodeficiency Syndrome, Mahul B. Amin, Michael P. Abrash, Eugene Mezger, Gary F. Sekerak

Henry Ford Hospital Medical Journal

Pneumocystis carinii is usually considered a respiratory tract pathogen; however, there are reported cases of limited and generalized dissemination of the organism from the lungs of immunocompromised patients. We present the autopsy findings of a 29-year-old male with acquired immunodeficiency syndrome (AIDS) and recurrent Pneumocystis carinii pneumonia who developed abnormal liver function tests. The patient had received aerosolized pentamidine because of toxic reactions to other modes of therapy. The postmortem examination revealed Pneumocystis in the lungs, liver, spleen, kidney, myocardium, thymus, pancreas, thyroid gland, bilateral parathyroid and adrenal glands, gastrointestinal mucosa, perihilar and mesenteric lymph nodes, and bone marrow. A …

Infant Hearing Screening 1984 To 1989: The Henry Ford Hospital Experience, Gary P. Jacobson, Mary Jo Burtka, Jeanne A. Wharton, Craig W. Newman, Neil Shepherd, Robert G. Turner

Henry Ford Hospital Medical Journal

From 1984 to 1989 the Infant Hearing Screening (IHS) program at Henry Ford Hospital identified 1,300 infants as being "at risk" for hearing loss. The prevalence of significant sensorineural hearing loss in this sample was 1.4%. Additionally, 80 infants who passed the IHS program and reached 3 years of age were found to have normal hearing sensitivity by conventional audiometric techniques (ie, no false-negative predictions). There were three false-positive predictions. It was discovered that infants of low birthweight (ie, < 1,500 g) were three times more likely to fail IHS than those whose weight exceeded 1,500 g. A higher return rate was found for infants failing an initial hearing screening conducted in the neonatal intensive care unit in comparison to those screened as outpatients one week postdischarge. The sensitivity and specificity of behavioral observation audiometry were 43% and 92%, respectively, when brainstem auditory-evoked potentials was used as the criterion validity measure.

Human Fetal Tissue: Scientific Uses And Ethical Concerns, Carol A. Tauer Ph.D.

Journal of the Minnesota Academy of Science

Human fetal tissue has been used in research for decades, but recent attempts to implant fetal neural tissue as therapy for Parkinson's disease have stimulated discussion of ethical and policy issues. In late 1989 a moratorium on federal support of fetal tissue transplantation research was indefinitely extended, based on the connection between this research and elective abortion. Four abortion-related objections to the use of fetal tissue can be identified: 1. The procedures of abortion and tissue procurement are linked in practice; 2. One who uses fetal tissue is complicit with the abortions which provided the tissue; 3. The prospect of …

The Role Of Small Peptides In Cancer Physiology And Chemotherapy, Bao-Ling Tsay

Theses and Dissertations in Biomedical Sciences

The targeting of proven anticancer drugs specifically to cancer cells would provide a unique opportunity to restrict neoplasms without damaging the cancer patient. The present research utilizes the phenomenon of illicit transport, i.e. the coupling of normally impermeant metabolites to permeant metabolites, in targeting the drug melphalan to mouse Ehrlich ascites tumor cells. The dipeptide beta-alanyl-melphalan was synthesized and tested in vitro for toxicity towards mouse Ehrlich ascites tumor cells, mouse liver cells, and mouse 3T3 embryonic cells. The parent compound, melphalan, was used as a control treatment. In addition, both melphalan and beta-alanyl-melphalan were utilized in in vivo chemotherapeutic …

Transcriptional Regulation Of The Human Calcitonin Gene: A Progress Report, Sara Peleg, Gilbert J. Cote, Ronald V. Abruzzese, Robert F. Gagel

Henry Ford Hospital Medical Journal

We have applied DNA transfer techniques lo study the transcriptional regulation of the calcitonin (CT) gene in a C-cell line (TT) derived from a human medullary thyroid carcinoma. TT cells were transfected with a fusion gene containing the CT gene promoter and 5' -flanking DNA attached to the promoter-less growth hormone gene (reporter). We quantitated the reporter gene product to monitor transcriptional activation by the CT promoter and deletion mutants of the 5' -flanking DNA. We found that the proximal CT promoter which includes the DNA sequence from +1 to -129 bp upstream from the CT transcription start site did …

Screening For Pheochromocytoma In The Men 2 Syndrome, J. Kotzerke, C. Stibane, H. Dralle, H. Wiese, W. Burchert

Henry Ford Hospital Medical Journal

Twenty-two patients with the multiple endocrine neoplasia type 2 (MEN 2) syndrome were screened for pheochromocytoma since it is a major cause of morbidity in MEN 2 families. Clinical symptoms, biochemical parameters, ultrasound, computed tomography or magnetic resonance imaging, and meta-iodo-benzylguanidine (MIBG) scintigraphy were evaluated for detection of adrenal tumors. Clinical symptoms and plasma or urine catecholamines appeared to be nonspecific, whereas MIBG scintigraphy was highly specific and the most sensitive parameter. Patients older than age 30 should be scintigraphically screened at least once despite the radiation exposure. Demonstration of only slight uptake is not an indication for surgery but …

The Concentration Of Prostaglandin E2 In Periradicular Lesions, Steve N. Mcnicholas

Loma Linda University Electronic Theses, Dissertations & Projects

Prostaglandins (PG) have been implicated in pathogenesis of periapical lesions. The purpose of this study was to determine the concentrations of PGE₂ in human periapical lesions. Periapical specimens from patients with clinical signs and symptoms of chronic and acute apical periodontitis were obtained and immediately frozen in liquid nitrogen. Periradicular tissues from unerupted third molars were frozen and used as controls. The concentration of PGE₂ was determined by radioimmunoassay. Low levels of PGE₂ were found in the control tissues as compared to those detected in chronic and acute lesions. A significantly higher level of PGE₂ was …

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 …

Three Cheers For Elective Hysterectomy, Mary Guinan

School of Public Health Faculty Research

Hysterectomy is the second (after cesarean section) most commonly performed major surgical procedure in the United States today.1 About [650,000 American women will have hysterectomies in 1989. Thirty-seven percent of all US women will have had a hysterectomy by the time they reach age 60. The number of hysterectomies increased dramatically Born 1965 to 1975, but then leveled off and decreased to the present level of about 7 per 1000 women. The ~ghest rates occur in women aged 35 to 44 years, the age group the so called baby boomers are now entering in large numbers. Therefore, if the age-specific …

Hypoxanthine-Induced Differentiation Of Cultured Human Leukemia Cells, Gayle Jennette Singleton

Chemistry & Biochemistry Theses & Dissertations

Human cultured leukemia cells appear to have a decreased amount of inosine in their tRNA. When cells with inosine deficient tRNA are placed in a hypoxanthine fortified media, they incorporate hypoxanthine into their tRNA by the action of the enzyme tRNA-hypoxanthine ribosyl transferase. This generates the nucleoside inosine in the tRNA. The cultured human leukemia cell lines, CCRF-CEM, HL-60, and HGPRT(-) HL- 60, incorporate hypoxanthine into their tRNA, as determined by tRNA isolation, hydrolysis, and HPLC analysis. Hypoxanthine treatment dramatically inhibited cell growth in conjunction with partial induction of differentiation in the CCRF-CEM, HL-60, and HGPRT ( - ) HL-60 …

Advances In The Diagnosis Of Urothelial Neoplasia, John D. Crissman, Richard J. Zarbo, Terri Johnson, V. Ramesh Babu, Fazlul H. Sarkar, Brian J. Miles, Joseph C. Cerny

Henry Ford Hospital Medical Journal

Urothelial neoplasia is a unique cancer in that it consists of a spectrum of tumors with different biologic behaviors. The most common urothelial neoplasm is the low grade superficial papillary carcinoma or papilloma which may recur numerous times but does not result in significant morbidity or mortality. A variant of the superficial papillary carcinoma, which represents approximately 10% of the tumors, is the noninvasive papillary neoplasm which progresses to a less differentiated invasive transitional cell carcinoma (TCC). Considerable effort has been directed at identifying which of the superficial well differentiated papillary tumors will persist, recur and progress to invasive cancer …
