Corticosterone Levels And The Critical Period In Imprinting Behavior Of Domestic Chicks, Lorraine Feldman

Biology ETDs

The following research was undertaken to monitor a glucocorticoid corticosterone to determine whether or not a reduction in glucocorticoids occurs during the critical period of imprinting behavior. Two groups of domestic chicks (Schaffer white Leghorns) were incubated, hatched and maintained under brooding conditions prior to imprinting procedures. Chicks were first divided into seven age groups, four hour intervals, beginning at hatching. The critical period of imprinting behavior was established with Group I. Success of imprinting training in this group was tested 24 hours after the training sessions. The second group provided blood samples taken after imprinting training sessions; they were …

Phenetic Structure And Zoogeography Of North American Insectivorous Bat Faunas, Gregory Michael Shum

Biology ETDs

Eighteen morphological features were measured for 103 species of insectivorous bats found throughout North America. These characters were standardized to a mean of zero and a standard deviation of unity. Using these morphological characters, thirty-one distinct faunas, ranging from a Boreal Forest fauna with three species to a Wet Tropical fauna with 50 species, were analyzed in an 18-dimensional mathematical hyperspace with the numerical taxonomic techniques of distance, correlation and principal components.

The results show that tropical faunas occupy a greater morphological hypervolume than temperate-zone faunas. Morphological packing is not greater in tropical faunas, and it appears that a limiting …

Efficacy Of Bunamidine Hydrochloride Against Immature And Mature Stages Of Echinococcus Granulosus, Lauritz A. Jensen

Theses and Dissertations

A study was conducted to determine the efficacy of bunamidine hydrochloride against the immature and mature stages of Echinococcus granulosus found in Utah. Twenty-seven dogs were obtained from local animal shelters and experimentally infected with the parasite. The drug was given at dosage levels of 25 mg/kg to 50 mg/kg of bodyweight. It was from 85.9 to 98.8% effective against the immature stage, and 100% effective against the adult stage. The results suggest that this drug can feasibly be used under field conditions where hydatid disease is endemic.

Physiological Adaptations Of Aquatic Turtles, Oscar Gloor

Honors Theses

Naturalists have long noted the remarkable ability of aquatic turtles to remain submerged for long periods of time. Only recently, though, has much serious attention been given to discovering the mechanisms which enable turtles to survive for so long in the relatively hypoxic aquatic environment.

Radionuclide Bone Imaging In The Evaluation Of Prostatic Cancer, Daniel S. Marks, William R. Eyler

Henry Ford Hospital Medical Journal

Radionuclide bone imaging is a rapid, easily performed, noninvasive method for evaluation of skeletal disease in carcinoma of the prostate, or any other malignancy. In a significant number of cases, it may provide the only evidence of metastases and frequently demonstrates more widespread Involvement than previously suspected. Thus, it may redirect the chosen course of therapy or localize sources of bone pain that are not radiographically apparent. Sixty-two percent of 42 patients studied were abnormal, of which 12% had no radiographic evidence of disease.

Lymphangiography In Staging Carcinoma Of The Prostate. A Comparison With Operative Findings, Joseph C. Cerny, Malcolm Weckstein, Riad Farah

Henry Ford Hospital Medical Journal

Pedal lymphangiography was performed In 30 patients who subsequently underwent radical retropubic prostatectomy, and radical pelvic lymphadenectomy. In 24 of 30 patients, lymphangiograms correctly predicted the presence or absence of nodal Involvement. In spite of certain limitations of the technique. It is considered an essential diagnostic study in patients considered for possible radical prostatic surgery, or in patients who may be candidates for external megavoltage radiotherapy to the prostate gland and its lymphatic drainage.

Immunologic Assessment In Patients With Prostatic Carcinoma, Richard C. Klugo

Henry Ford Hospital Medical Journal

The role of immune mechanisms in the development and control of prostatic carcinoma appears to be complicated by the endocrine response of some tumors. The progression of endocrine-independent tumors is more directly related to host-immune response. Evaluation of the role of chemotherapeutic agents must include their effect on the host-immune response. The use of BCC in patients with metastatic prostatic carcinoma produces no alteration in cell-mediated immunity but produces local tumor necrosis. The use of nonspecific antigens to enhance host-immune response may be more effective when used as adjuvant therapy in earlier stages of prostatic adenocarcinoma.

Bone Marrow Acid Phosphatase In The Evaluation Of Patients With Carcinoma Of The Prostate, Ronald Kabler, Riad Farah, Kenneth Greenawald, Joseph C. Cerny

Henry Ford Hospital Medical Journal

Based on experience with 30 men having clinical stage A and B adenocarcinoma of the prostate, the authors conclude that elevation of bone marrow acid phosphatase (BMAP) is a sensitive indicator of the disease state. BMAP revealed periprostatic or nodal Involvement when osseous metastases seemed absent. BMAP is considered essential in the evaluation of all patients with prostatic carcinoma. Patients who have false negative BMAP (and are not candidates for radical prostatectomy), should undergo lymphangiography and bone scan before radiation therapy or hormonal treatment is planned.

Radical Retropubic Prostatectomy And Pelvic Lymphadenectomy In Carcinoma Of The Prostate, Riad N. Farah, Joseph C. Cerny

Henry Ford Hospital Medical Journal

An operative technique Is described which combines regional pelvic lymphadenectomy with radical prostatectomy. The technique has been used on 30 patients with no operative mortality. Morbidity has been within acceptable limits. Thus far, only one patient has shown recurrence of the neoplasm.

Hormonal And Chemotherapeutic Management Of Disseminated Carcinoma Of The Prostate, Robert W. Brownlee

Henry Ford Hospital Medical Journal

The management of disseminated prostatic carcinoma with hormonal and chemotherapeutic agents is discussed. Hormonal manipulation consists of ablative as well as additive modalities. A new agent, Adriamycin, has shown some effectiveness In selected cases. Significant difficulties are encountered in assessing the objective state of remission of patients undergoing therapy. Further advances through co-operative, randomized clinical trials must be sought. The development of additional chemotherapeutic agents will hopefully expand our horizons.

Palliative Urinary Diversion In Adenocarcinoma Of The Prostate, R. C. Youngman, Joseph C. Cerny

Henry Ford Hospital Medical Journal

Ten patients with inoperable prostatic carcinoma, producing ureteral obstruction and azotemia, underwent palliative urinary diversion. Good quality survivals of two months to three years were obtained. These results compare favorably with the good results seer) In gynecologic neoplasm of the bladder, colon and breast. In selected cases of carcinoma of the prostate, palliative urinary diversion is indicated when the prospects exist for further benefit from chemotherapy or radiotherapy.

Advances In The Radiation Therapy Of Carcinoma Of The Prostate, Joel Elliot White

Henry Ford Hospital Medical Journal

Basic principles of radiation biology and radiation tolerance are reviewed. The Implications for radiation therapy of newer staging techniques in carcinoma of the prostate such as exploratory laparotomy, lymphangiography, and bone marrow acid prosphatase are discussed. A technique for treating the prostate and para-aortic lymph nodes in continuity is presented. Complications and results of therapy are discussed.

Changes In Serum Testosterone After Bilateral Orchiectomy In Patients With Metastatic Carcinoma Of The Prostate, Richard Senn, Riad Farah, Julius Ohorodnik, Joseph C. Cerny

Henry Ford Hospital Medical Journal

From a study of 38 patients, it may be concluded that, first, changes in serum testosterone levels of patients undergoing orchiectomy for metastatic carcinoma of the prostate are unrelated to the clinical course of the patient; second, no clear correlation exists between quantitative Leydig cell counts and levels of plasma testosterone; and, third, exacerbation of metastatic disease is observed while plasma testosterone remains in the castrate range. These observations question the exact function of the Leydig cell and its role in androgen production, and indicate that prostatic neoplasms have varying degrees of response to reduced androgen levels and/or androgen-Iike substances …

Separation Of Spores And Parasporal Crystals Of Bacillus Thuringiensis In Gradients Of Certain X-Ray Contrasting Agentsseparation Of Spores And Parasporal Crystals Of Bacillus Thuringiensis In Gradients Of Certain X-Ray Contrasting Agents, Eugene S.

Lipid Metabolism During Bacterial Growth, Sporulation, And Germination: Differential Synthesis Of Individual Branched And Normal-Chain Fatty Acids During Spore Germination And Outgrowth Of Bacillus Thuringiensis, Kenneth W. Nickerson, Lee A. Bulla Jr., Timothy L. Mounts

Papers in Microbiology

The biosynthesis of individual branched- and normal-chain fatty acids during Bacillus thuringiensis spore germination and outgrowth was studied by comparing pulsed and continuous labeling of these fatty acids with [U- ¹⁴C ]acetate. The relative specific activity of each fatty acid varies with time as the cell progresses through outgrowth. However, fatty acid synthesis does occur in two distinct phases. Upon germination, acetate is incorporated only into the iso-isomers i-C₁₃, i-C₁₄, and i-C₁₆; no normal or anteiso synthesis occurs. Subsequent to T₃₀, the full complement of branched- and normal-chain homologues is formed …

Vocalizations Of Isolated Piglets. Ii. Some Environmental Factors, D. Fraser

Communication Skills Collection

The vocalizations of suckling piglets were studied during brief tests which involved social isolation, restriction of movement, and exposure to unfamiliar surroundings. Similar trends were shown in most cases by the three classes of call studied - closed mouth grunts, open mouth grunts, and squeals. The rate of calling was much lower when a piglet was in the home pen than when alone in an unfamiliar pen, and more calls were given in both situations when the animal’s movement was restricted by caging. The presence of the dam and four littermates in unfamiliar surroundings caused a large reduction in calling, …
