Hepatic Ornithine Metabolism In Hydrazine-Treated Rats, Van Saxton Hubbard

Theses and Dissertations

Ornithine plays an important role in mammalian intermediary metabolism. Ornithine can be (1) utilized as a component of the urea cycle, (2) decarboxylated to form putrescine, a precursor of the polyamines, spermidine and spermine, and (3) converted metabolically to arginine, proline and glutamate. In prior investigations conducted in our laboratories and others, free endogenous hepatic pools of ornithine were found to be elevated following hydrazine administration. Consequently, time-course alterations of arginase, ornithine δ-transaminase, ornithine transcarbamylase, and ornithine decarboxylase activities were investigated regarding the effect of hydrazine treatment on hepatic ornithine metabolism in the rat. As an outgrowth of these investigations, …

Synthesis And Evaluation Of Some Arylalkenyl And Arylepoxyalkyl Hydrogen Succinates And Hydrogen Glutarates As Inhibitors Of Rat Liver Β-Hydroxy-Β-Methylglutaryl Coenzyme A Reductase, Paul Emil Marecki

Theses and Dissertations

Atherosclerotic disease is an almost universal phenomenon and increases in severity and frequency with increasing age. Atherosclerosis may contribute to several disorders including bursting of an artery, blockage of an artery, or induction of arterial clotting. The culmination of these diseases is usually premature since at the time of death the unaffected organs are in reasonably satisfactory condition and could have operated for several more years. Among the many factors which act in concert to produce the disease, serum cholesterol levels play a central role. It has been suggested that the lowering of cholesterol levels will provide an effective means …

Light And Electron Microscopy Investigation Of Developing Wheat Caryopses Infected By Tilletia, Melvin Douglas Grove

Theses and Dissertations

Caryopses of wheat were studied during infection by Tilletia caries and T. controversa. Initially the pathogens penetrated embryos of the host. After the embryo tissue was consumed by the fungi, endosperm tissue was penetrated and consumed. Initial penetration of endosperm tissue was in localized areas. During infection the fungus mycelium spread intercellularly, but occasionally was seen intracellularly. As the host tissue was consumed teliospores were formed. At maturity a host cell layer 4-6 cells thick remained which retained the mature teliospores. Histochemical studies indicated that carbohydrates and lipids of the host disappeared soon after invasion by the pathogens. Nuclei and …

Ultrastructure Of Histochemically Localized Cholinesterases In Central And Peripheral Nervous Systems Of Two Insects: Periplaneta Americana L. And Acheta Domestica L, Clifford James Stratton

Theses and Dissertations

Cholinesterase (ChE) was histochemically localized by three methods in the sixth abdominal ganglion and the femur of crickets and cockroaches using light and electron microscopy. The light microscopy showed that ChE in insect femur could be readily demonstrated. The ultrastructural data showed enzyme activity: in ganglion - neural lamella, perineurium, axolemma, inside axons, along glia and at probable synapses; in peripheral nerves - in glial cells, sarcoplasmic reticulum, T-system, axolemma, sarcolemma and at neuromuscular junctions. All activity was inhibited with 10-4 eserine except in the neural lamella, suggesting cholinesterase at all of the above sites except the neural lamella where …

The Effects Of Deficiencies Of Certain Mineral Nutrients On The Activity And Various Properties Of Ribulose-1,5-Diphosphate Carboxylase From Barley (Hordeum Vulgare L.), Philip Alan Harrison

Theses and Dissertations

Barley plants grown in Mg, Mn, Zn and Cu deficient media were analyzed for specific activity, total activity and amount of RuDPCase present. Percent dry weight, as well as chlorophyll and soluble protein content were determined. All deficiencies caused lower chlorophyll and RuDPCase concentrations than occurred in the control. Soluble protein content, however, was higher in all deficient plants than in the control, either on a dry or a fresh weight basis. The addition of 18 μM Mn^2+ increased the activity of Mg^2+ containing RuDPCase preparations as much as 133% above normal. The specific activity of RuDPCase from Mg, Mn, …

The Effects Of Penicillin Upon The Fission Rate Of Dugesia Dorotocephala., John J. Fahsbender

Theses and Dissertations

Planaria (class Turbellaria) are the highest life forms which exhibit fission (Hyman, 1951). The laboratory planarian, Dugesia, lives in lakes, ponds, streams and springs, where it occupies bottom habitats. Fissioning is an asexual mode of reproduction. The fission plane is usually transverse, forming behind the pharynx, and separation appears to be dependent upon locomotion (Curtis, 1902). The posterior half of the worm adheres to the substratum while the anterior half continues to move forward until the worm snaps in two. Each half then regenerates the missing parts, forming two new smaller worms.

The Effects Of Thiamin Deficiency And Thiamin Antagonists On Cardiac Function In The Rat, D. James B. Sutherland

Theses and Dissertations

A study was made to determine what biochemical changes were involved in the slowing of the rat heart rate during thiamin deprivation, pyrithiamin or oxythiamin treatment. The appearance of bradycardia during progressive thiamin deficiency was shown to be related to the reduction in myocardial enzymatic activity of pyruvate (PDH) and 2-ketoglutarate (2-KGDH) dehydrogenase, and not due to inanition alone since pair-fed control rats did not show bradycardia until the agonal stage. Bradycardia was not the result of reduced energy since CP, ATP, ADP, and AMP levels remained normal even though PDH and 2-KGDH activity dropped to 20% of normal by …

The Determination Of Thiamin And Its Derivatives In Brain Tissue Of Control, Thiamin-Deficient, Oxythiamin- And Pyrithiamin-Treated Rats, David S. Murdock

Theses and Dissertations

|Ni.|Pa Calorimetric Study Of The Heat Of Ionization Of Water At 10 And 40°C, And,|Nii.|Pa Calorimetric Determination Of The Heat Of Reaction Of Tris (Hydroxymethyl) Aminomethane (Tham) With Hydrochloric Acid In Aqueous Solution At 10, 25, And 40°C, Griffith Lyn Kimball

Theses and Dissertations

The heat of neutralization, ΔH_-N, of perchloric acid with sodium hydroxide has been determined at 10 and 40° in a low ionic strength, μ, region using a nonisothermal, constant-temperature-environment solution calorimeter. Correction of the data to infinite dilution by extrapolation of a plot of ΔH_-N vs μ^0.5 gives values at zero ionic strength for the heat of ionization of water of 14.216 and 12.695 kcal/mole, respectively, at 10 and 40° . The data are correlated with those of earlier workers to give an equation allowing the calculation of the heat of ionization of water at zero ionic strength over the …

Reactions Of N₂F₄ And Sf₆ With H₂ Induced By Co₂ Laser Pulses And By Electrical Discharge, John Leslie Lyman

Theses and Dissertations

A high power pulsed CO_2 laser was used to induce reactions in gas mixtures containing either N_2F_4 or SF_6. The rate of laser induced dissociation of N_2F_4 to NF_2 was as much as 1000 times faster than the thermal rate, and the rate law was of lower order than the thermal, bimolecular rate law. Explosion threshold and induction time data were obtained for butene stabilized mixtures of N_2F_4 and H_2. HF laser gain was observed during the first few microseconds of CO_2 laser pulse, but it was strongly quenched by the explosion. The laser driven reaction of SF_6 with H_2 …

A Proposed Mechanism Of Action For In Vitro Excystation Of Two Species Of Coccidia, William Ronald Jolley

Theses and Dissertations

Excystation of coccidian oocysts is accomplished in vitro by altering wall permeability with CO2 and a reducing agent, then activating the enclosed sporozoites with a solution of trypsin and bile. Elucidation of the mechanism of action of the CO2-reducing agent treatment was the basic intent of this study. Oocysts of Eimeria stiedae (rabbit) and E. tenella (chicken) were tested for the presence of an excystation-associated enzyme by incubating sporulated oocysts in fluids extracted from variously treated oocysts, and by carbon-14 labelling; the effect of CO2 -reducing agent treatment on oocyst walls was investigated by titration with acid or base for …
