Mechanism Of Toxicity Of 2-Thiotriazone (Ttz) In Rats., Twintillia Murphy Tate Jan 1989

Mechanism Of Toxicity Of 2-Thiotriazone (Ttz) In Rats., Twintillia Murphy Tate

LSU Historical Dissertations and Theses

The mechanism of action of 2-thiotriazone (TTZ) was evaluated in adult and immature rats of both sexes. TTZ produced marked pulmonary toxicity in rats that was both age and sex-dependent. It was highly toxic in male rats (oral LD50 of 4.6 mg/kg and ip LD50 of 1.4 mg/kg). Female rats were more resistant than males and immature rats (30-40 days of age) were totally resistant to TTZ toxicity. Gross and histological examination of lung tissue from rats exposed to TTZ showed severe pulmonary edema, effusion and mottling of the lungs. Significant increases in lung weights were also observed. Diethylmaleate (DEM) …

Faculty Publications

This experiment was designed to evaluate the ability of three different somatic cell cultures to promote development of early cleavage stage pig embryos. A total of 245 2-cell, 4-cell, 8-cell, and 16-cell pig embryos were cocultured for 5 days with porcine oviductal epithelial cells (POEC), porcine fetal fibroblast monolayer (PEF), a combined POEC and PEF coculture system (PEF-POEC), or Dulbecco's Modified Eagle Medium alone (DMEM). Embryos were collected at slaughter from the reproductive tracts of superovulated prepubertal gilts. Embryos were recovered, evaluated, and randomly placed in one of the four treatment groups. POEC were recovered from oviductal flushes, washed, and …

Comparison Of Clinical Isolates Of Klebsiella Pneumoniae To Klebsiella Sp. Isolated From Summer Harvested Eastern Oysters, Crassostrea Virginica (Gmelin)., Thomas Elbert Graham Jan 1989

Comparison Of Clinical Isolates Of Klebsiella Pneumoniae To Klebsiella Sp. Isolated From Summer Harvested Eastern Oysters, Crassostrea Virginica (Gmelin)., Thomas Elbert Graham

LSU Historical Dissertations and Theses

Suspected environmental fecal coliform positive Klebsiella sp. oyster isolates were analyzed and compared to human clinical isolates of Klebsiella pneumoniae. Oyster isolates were urease negative (at 24 hours) and were identified as K. pneumoniae using API 20E biochemical test strips. The ability to produce fecal coliform reactions was lost by 65% of the oyster isolates after undergoing several passages on brain-heart-infusion agar at 20$\sp\circ$ to 25$\sp\circ$C. Tests with 4-methylumbelliferyl-B-d-glucuronide (MUG) found both oyster and clinical isolates to be MUG negative. Moles % guanine plus cytosine (mol% G + C) information indicated that oyster isolates had mol% G + C values …

Reference Standards For Flow Cytometry And Application In Comparative Studies Of Nuclear Dna Content, Terrence R. Tiersch, Robert W. Chandler, Stephen S. Wachtel, Sherman Elias Jan 1989

Reference Standards For Flow Cytometry And Application In Comparative Studies Of Nuclear Dna Content, Terrence R. Tiersch, Robert W. Chandler, Stephen S. Wachtel, Sherman Elias

Faculty Publications

Nuclear DNA mass in cells from a reference species can be used to obtain high‐resolution estimates of DNA mass from a target species. In our study of DNA mass in cells from 45 selected species, representing each of the major vertebrate classes, we have obtained values of from 1.5 to 110.0 pg of DNA. Because values in or near this range would be expected in the study of nuclear DNA mass in vertebrates and other organisms, the species in this report can provide a useful catalogue of references for comparative studies of DNA.

Reality And Knowledge In Voegelin's Political Philosophy. (Volumes I & Ii)., Seung-Hyun Baek Jan 1989

Reality And Knowledge In Voegelin's Political Philosophy. (Volumes I & Ii)., Seung-Hyun Baek

LSU Historical Dissertations and Theses

It is the primary aim of this dissertation to draw attention to Voegelin's political philosophy and to place it at the center of the conduct of political inquiry, by criticizing positivistic political epistemology. Though scientism had become a dominant commitment, it does not provide an appropriate approach to political knowledge. Making reality dependent on methodology, it neglects important political existence, and fails to ask deeper questions about the truth-content political reality. However, there is an extra-spatio-temporal reality, that we can know, albeit imperfectly, and not discovered by the modern scientific methods. By means of the restoration and "retheoretization" of the …

Vegetative Compatibility Groups Of Fusarium Oxysporum F. Sp. Lycopersici And Nonpathogenic Strains Of F. Oxysporum And An Isozyme Analysis Of Pathogenic Populations., Karol Sue Elias Jan 1989

Vegetative Compatibility Groups Of Fusarium Oxysporum F. Sp. Lycopersici And Nonpathogenic Strains Of F. Oxysporum And An Isozyme Analysis Of Pathogenic Populations., Karol Sue Elias

LSU Historical Dissertations and Theses

A worldwide collection of 112 isolates of Fusarium oxysporum f. sp. lycopersici (FOL) from tomato was examined for pathogenicity, colony morphology, vegetative compatibility, and isozyme polymorphism. There were no correlations among colony morphology with age of culture, race, vegetative compatibility group (VCG), or geographic origin. Vegetative compatibility group 0030 contained all three races of FOL from throughout the world and all colony morphology types. Vegetative compatibility groups 0031 and 0032 contained races 1 and 2, but their geographic ranges were somewhat more limited. In addition, 50 isolates of FOL were the sole members of their own VCGs. Thus, there was …

An Evaluation Of Multiple Aspects Of Asthmatic Functioning: Stress Responders Versus Stress Nonresponders., Anthony Joseph Goreczny Jan 1989

An Evaluation Of Multiple Aspects Of Asthmatic Functioning: Stress Responders Versus Stress Nonresponders., Anthony Joseph Goreczny

LSU Historical Dissertations and Theses

The purpose of this study was to differentiate between asthmatics whose daily symptoms are related to daily stress level (stress responders) and those whose symptoms have no apparent relation to stress (stress nonresponders) and to indentify differences between the two groups. Using correlational procedures, 15 stress responders and 19 stress nonresponders were identified and compared along various dimensions. Multivariate analysis of variance (MANOVA) and covariance (MANCOVA) procedures revealed no significant differences between the two groups with respect to affective/emotional responding, clinical symptomatology, or cognitions about illness and asthma. In addition, regression models using the Asthma Symptom Checklist Panic-Fear subscale, a …

Lipopolysaccharide Serotyping Of Vibrio Vulnificus., Stephen Jeffrey Martin Jan 1989

Lipopolysaccharide Serotyping Of Vibrio Vulnificus., Stephen Jeffrey Martin

LSU Historical Dissertations and Theses

Current schemes used to serotype Vibrio vulnificus are based on direct bacterial agglutination using polyclonal rabbit antisera. During the course of serotyping Louisiana V. vulnificus isolates we failed to observe a reproducible agglutination profile for these isolates. The major obstacle in producing serovar specific sera has been the failure to produce high titered anti-LPS sera in rabbits. Anti-LPS serum from rabbits immunized with formalin-killed, heat-killed, or acetone dried whole cell vaccines and LPS-carrier conjugates uniformly produced titers $\leq 320$. Separation of anti-LPS activity from whole sera by affinity chromatography also yielded low titered antisera. A typing system predicated on the …

The Lactate Threshold And Carbon Dioxide Flow To The Lung As Predictors Of Ventilation During Exercise., Becky Anne Baker Jan 1989

The Lactate Threshold And Carbon Dioxide Flow To The Lung As Predictors Of Ventilation During Exercise., Becky Anne Baker

LSU Historical Dissertations and Theses

Three studies were performed to determine the relationship between blood lactate, CO$\sb2$ flow to the lung, and ventilation during exercise. First, the method of determining the lactate threshold by use of log-log and semilog transformations developed by Beaver and his colleagues was modified to provide an objective method of determining the threshold which resulted in a significantly better fit (p $<$.05) of the log-log model to the data. Second, to test the theory that the increase in CO$\sb2$ flow to the lung due to bicarbonate buffering of H+ from lactic acid causes the rise in ventilation out of proportion to VO$\sb2$ at the ventilatory threshold, the lactate thresholds of these subjects were used to predict their ventilatory thresholds. The lactate threshold determined by the modified log-log model/method was a poor predictor with an insignificant relationship between the lactate and ventilatory thresholds (p $>$.05). In the third study, six subjects were tested during 4 sessions to determine the relationship between ventilation and CO$\sb2$ flow to the lung during exercise and also during rest and exercise while CO$\sb2$ was being inhaled. This relationship …

La Programacion Espacio/Temporal Del Relato., M. Ellen Blossman Jan 1989

La Programacion Espacio/Temporal Del Relato., M. Ellen Blossman

LSU Historical Dissertations and Theses

La programacion espacio/temporal es el conjunto de dos elementos: el elemento espacial, que implica la organizacion del proceso por el cual se enlazan los espacios discretos mediante la sintagmatica; y el elemento temporal, que implica la representacion cronologica de la organizacion narrativa. A veces dicha representacion cronologica no coincide con el orden logico de los acontecimientos. Esto puede ocurrir por la intercalacion de la metaficcion en la ficcion. Tanto la ficcion como la metaficcion se componen de esa unidad espacio/temporal, aunque no siempre los dos elementos de esta unidad se presenten explicitamente en la superficie del texto.

The Treatment Of Thomas Hobbes In Twentieth Century Political Thought., David Randolph Cole Jan 1989

The Treatment Of Thomas Hobbes In Twentieth Century Political Thought., David Randolph Cole

LSU Historical Dissertations and Theses

In the wake of the political upheavals of the twentieth century, political theorists have rediscovered the unsentimental teachings of Thomas Hobbes. Hobbes was a philosopher of order during a period of disorder--the English Civil War. He taught that sovereignty ought to be absolute and unchallengeable, so that order might be preserved. In particular, the sovereign ought to have the power to approve or disapprove political and religious teachings--in effect, to establish an unchallengeable "civil theology." Hobbesian sovereignty might preserve order, but it would also cut off political discussion and debate in summary fashion. In the twentieth century, political theorists have …

Dispersion And Physiological Ecology Of Mosquito Adults In Louisiana Ricelands., Alan Richard Holck

LSU Historical Dissertations and Theses

A sampling technique for estimating the size of adult mosquito populations in vegetation was developed. Regression analysis was used to obtain absolute density estimates from sweep net. Diurnal population size estimates of Louisiana riceland mosquitoes were made on a 35.6-square km site 5 km south of Kaplan, LA. Four mosquito species were present: Psorophora columbiae, Anopheles quadrimaculatus, An. crucians and Culex salinarius. Mosquito species were highly stratified in their distribution. Psorophora columbiae was primarily observed in pastures with livestock and in rice fields. Both Anophelines were found only in structures. Culex salinarius did not exhibit habitat preference. Anopheles quadrimaculatus exhibited …

Agrobacterium Tumefaciens - Mediated Transfer Of Plant Dna For Gene Expression Analysis., Woo Sung Lee Jan 1989

Agrobacterium Tumefaciens - Mediated Transfer Of Plant Dna For Gene Expression Analysis., Woo Sung Lee

LSU Historical Dissertations and Theses

Agrobacterium tumefaciens causes crown gall tumor primarily in dicotyledonous plants. The infection mechanism reveals that a portion of bacterial DNA (T-DNA) is transferred into the plant nuclear genome. This transformation system is widely utilized in plant genetic engineering and plant molecular biology. In this dissertation, two experiments were carried out. First, the copy number, physical structure and F1 segregations of T-DNA copies were analyzed, attempting to understand the mode of T-DNA integration into the plant genome. While the mechanism of Agrobacterium response to plant signals and generation and transfer of T-DNA intermediates through actions of virulence genes is generally understood, …

Dangerousness: Risk Assessment For Violent Behavior., Charles Edward Shaffer Jr Jan 1989

Dangerousness: Risk Assessment For Violent Behavior., Charles Edward Shaffer Jr

LSU Historical Dissertations and Theses

Federal court decisions and state and federal legislation have made the legal concept of dangerousness the predominant criterion in involuntary mental health hospital commitments and in determining the least restrictive custody level in prison inmate custody assignments. However, no adequate consensual definition with empirical methods of measurement exists. Megargee's (1976) definition of dangerousness as the probability of violent behavior was used as the basis for an empirical approach to measuring dangerousness in this study. Recent studies in the literature (Monohan, 1984; Klassen & O'Conner, 1988) suggested that discriminant analysis might be an appropriate methodology for model development. Review of the …

Molecular Biological Studies On The Degradation Of Diphenyl Ethers By Bacteria., Hung-Ming James Liaw Jan 1989

Molecular Biological Studies On The Degradation Of Diphenyl Ethers By Bacteria., Hung-Ming James Liaw

LSU Historical Dissertations and Theses

Microbial degradation of diphenyl ethers was studied utilizing several different approaches. The first approach was to isolate mutants from a ligninolytic Erwinia sp. by conventional mutagenesis and selection. A copper-resistant mutant, designated as Erwinia sp. CU3614, was isolated and characterized to be capable of degrading diphenyl ethers as well as one dibenzo-p-dioxin in the presence of copper ions. Isolation of Tn5 transposon-induced mutants of Erwinia sp. CU3614, which lost degradation ability, demonstrated that in all probability a copper-associated activity in the biotransformation of aromatic ethers was involved. In order to study the degradation at the molecular biological level, a 2.1 …
