Demonstration Of Unique Mycelial Components In Candida Albicans, David Jon Mancuso

Biological Sciences Theses & Dissertations

Mycelial (M) and blastopore (B) cell homogenates of Candida albicans strain BJ85 were compared to detect and recover unique M components. Qualitative differences in the protein and lipid content of Mand B homogenates were suggested by discontinuous polyacrylamide gel electrophoresis (DPAGE). In addition, a quantitative and possibly qualitative shift in the protein content during germ tube formation was implied by DPAGE. Unique M components were detected using both DPAGE and immunoelectrophoretic (IE) techniques. One unique M component by DPAGE, four by IE, and two by combined DPAGE and IE techniques were suggested. Of these three methods, only DPAGE and the …

Ultrasonic Versus Hand Filing Of The Human Root Canal System, Howard W. Scholz Jr.

Loma Linda University Electronic Theses, Dissertations & Projects

A comparison was made of ultrasonic filing versus hand filing using three solutions to flood the canals of 24 extracted human maxillary central incisors. A modified PR-30 Cavitron insert was used in a Cavitron 1010 unit for the ultrasonic filing. The clinical crown was removed with a diamond saw and water spray at the cemento-enamel junction. The two major groups were ultrasonic filing versus hand filing; the three subgroups were solution/solvents - 10% EDTA, 2.0% NaOCl, and distilled water.

After filing, the roots were grooved longitudinally with a high speed bur and cracked opened with a mallet and chisel. The …

The Effect Of Endodontic Therapy On The Incidence Of Radiation Caries In Dogs, James A. Abbott

Loma Linda University Electronic Theses, Dissertations & Projects

Endodontic therapy was evaluated as a possible control or prevention modality of radiation type dental caries in dogs. Two adult male dogs with permanent dentitions had endodontic therapy performed on alternating teeth in each jaw. The nontreated teeth served as controls.

The dogs were irradiated with 7000 rad Cobalt-60 radiation fractionated over an eight week period. The dogs were killed at 60 and 182 days post-irradiation. The teeth were removed from the jaws and immersed in methylene blue dye, sectioned, and the dye penetration pattern photographed. Diffusion of the dye into the tooth structure was quantified and statistically analyzed.

Human Placental Alkaline Phosphatase And Steroid Metabolism By Rat Adrenals, Allen G. Meier

Loma Linda University Electronic Theses, Dissertations & Projects

Human placental alkaline phosphatase was purified by butanol extraction, methanol precipitation and chromatography on DEAE-cellulose. The pH optimum was found to be 10.9. The enzyme was competitively inhibited by di-ethyl-p-nitrobenzyl-phosphonate and copper sulfate. An increase in enzymatic activity occurred in the presence of the phosphate ion (HPO₄) and ATP.

The enzyme was crystallized from a 40% saturated solution of ammonium sulfate and shown to be homogeneous by sedimentation analysis. Homogeneity of the enzyme was also demonstrated using poly-acrylamide-gel-electrophoresis. At a pH of 7.5% the electrophoretic pattern yielded a single band and showed no significant contamination.

The metabolic transformation …

Apical Closure Induction Using Bone Growth Factors And Mineral Trioxide Aggregate, Kenneth W. Tittle

Loma Linda University Electronic Theses, Dissertations & Projects

This study compared the ability of three different bone growth factor combinations with that of Ca(OH)₂ to stimulate apical closure as well as the effectiveness of Mineral Trioxide Aggregate (MTA) as an apical barrier. Fifty-six roots of second and fourth mandibular premolars of seven six- month old beagle dogs were used. Periradicular lesions were created over a four week period. The canals were cleaned and shaped and filled with Ca(OH)₂ for one week. They were then irrigated and received one of seven different treatments in a balanced design. Growth factors were placed in a carboxymethylcellulose carrier and delivered …

A Biosystematic Investigation Of Medically Important Yeasts, Nancy Christiansen Ballot

University of the Pacific Theses and Dissertations

The purpose of this study is twofold: (1) conduct an epidemiological survey of yeasts found in clinical material; and (2) suggest an identification scheme that would identify yeasts of medical importance in the shortest possible time.

The Biochemistry Of Vascular Smooth Muscle In The Spontaneously Hypertensive Rat, John Edward Taylor

University of the Pacific Theses and Dissertations

Cyclic adenosine 3’,5’-monophosphate (cAMP) was first described as the mediator of the glycogenolytic effect of epinephrine and glucagon in the liver almost two decades ago. It has since been found that cAMP may mediate the effects of a number of hormones and neurohormones, and this observation has led to the development of the second messenger hypothesis of hormone action. According to the second messenger theory, the hormone or first messenger brings information to the cell, whereas, the second messenger (cAMP) transfers this information into intracellular events. More recent evidence has described the existence of an additional second messenger, cyclic guanosine …

Duck Plague Virus An Investigation Of Cytopathic Effects, In-Vitro Host Range, And Inhibition By Phosphonoacetic Acid, Ronald Attanasio

Biological Sciences Theses & Dissertations

Duck plague is a hemorrhagic, necrotic disease found exclusively in the order Anseriformes, family Anatidae (ducks, geese, swans). The etiologic agent has been reported to be a herpes-like virus. The Holland strain of duck plague was found to induce cytopathic effects in cell culture (perinuclear vacuolation followed by lysis). A simple reproducible plaque assay for quantitating the virus was developed. Under conditions of the plaque assay, one-hit kinetics were observed. The host range of duck plague virus in cell culture was found to include the order Galliformes, family Phasianidae (pheasants, quails and partridges). Duck plague virus-induced cell culture cytopathic effects …
