Henry Ford Hospital Medical Journal

Normal and hypophysectomized rats were divided into equal homogeneous groups to determine the effect of cholestyramine, corn oil and cholesterol on the excretion of fecal bile acids and sterols. Bile acid turnover rates, pool sizes, and spectrums were studied and compared.

Normal Serum Protein Levels In Syrian (Golden) Hamsters: Compared With The Protein Levels In Sv 40 Tumor Bearing And Sv 40 Immune Hamsters, Hajime Hayashi, Nansie Sharpless, Gerald A. Logrippo

Henry Ford Hospital Medical Journal

A study of 149 hamsters indicates that there are periods in life when the animal is immune to tumor induction by a known virus. By studying normal serum protein levels, standards were established for the adult age and for the tumor forming period. The data emphasize the importance of the immunologic status of the host for virus induction of tumors.

The Effect Of Glucose On Neutrophilic Phagocytosis, Donald F. Adams

Loma Linda University Electronic Theses, Dissertations & Projects

Samples of blood were obtained from thirty healthy young adult males (Loma Linda University School of Dentistry), and contaminated with bacteria. Varying concentrations of pure glucose were added to this mixture to observe the effect of the glucose on in vitro neutrophilic phagocytosis. As the glucose levels increased a statistically significant suppression was noted in the ability of the neutrophilic leukocytes to engulf Staphylococcus epidermidis.

It was not possible, however, to predict the degree of suppression for any particular level of glucose added nor is it possible to state that suppression will occur in any one individual.

Two methods of …

The Effects Of A Nerve Growth-Promoting Protein On The Integument Of Pet Mice, Craig Bauman Satterlee

Master's Theses

A factor which specifically stimulates the growth of sensory and sympathetic nerve cells has been under investigation for a number of years. This factor, originally isolated in 1951, from mouse sarcomas 37 and 180, was named the "nerve growth factor". Its action was first shown in vivo by inoculating the sarcoma into chick embryos and subsequently in vitro by culturing chick ganglia and mouse sarcoma together. In the years immediately following the initial discovery, much more potent sources of NGF were found in the salivary glands and salivary secretions of a variety of species. These include rattle snake venom, and …

Nutritional Relationship Between The Copepod Parasite Charopinus Dentatus (Wilson) (Lernaeopodidae) And The Skate Host, Raja Binoculata Girard, Donald W. Rigby

Loma Linda University Electronic Theses, Dissertations & Projects

Of 1,798 parasitic copepods, Charopinus dentatus (Wilson), collected from the skate host, Raja, binoculata Girard, 1,615 (89.87.) were obtained from the mucosa lining the mouth and pharynx. None were collected from the gill filaments. Host tissue damage was not seen grossly or microscopically around the attached parasite nor did the gut contents of female parasites give evidence microscopically or chemically that they are blood feeders. Green material from the gut of female parasites was made up of cell-like structures occurring singly and in clumps. Spectrophotometrically this material demonstrated spectral maxima (670, 410 'FM) similar to maxima of degradative products of …

A Consideration Of Infraspecific Categories In The Genus Echinococcus Rudolphi, 1801 (Cestoda: Taeniidae), Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Echinococcus granulosus (Batsch, 1786) and E. multilocularis Leuckart, 1863, have been considered polytypic species, nine and three subspecies, respectively, having been recognized mainly on typological grounds. However, limits of taxonomically significant morphological and physiological variation have not been defined, nor do we know the degree to which such variation is influenced by species of host. With the probable exception of E. g. canadensis Cameron, 1960, the recognized subspecies of E. granulosus occur sympatrically with the nominate subspecies, E. g. granulosus, of European origin. Because there are no well-defined predator-prey relationships which would ensure their ecological isolation, seven of these …

A Study Of The Calcium, Phosphorus And Magnesium Balance In Phenylketonuric Children, Rita Go Wong

Loma Linda University Electronic Theses, Dissertations & Projects

The calcium, phosphorus and magnesium retention of six female phenylketonuric children was studied to determine whether the percentage retention of these minerals would be comparable to the values for normal children established by Lutwak and Macy. ^73,78,79 A constant diet was given to the subjects and carmine was used as stool marker. The food and fecal specimens were analyzed for calcium, phosphorus, magnesium and total lipids. Urinary specimens were analyzed for calcium, phosphorus, magnesium and creatinine. Calcium and magnesium levels were determined in the serum of four subjects. The percentage of retention of calcium, phosphorus and magnesium was determined from …

The Nitrogen Nutrition Of Emmonsia (Moniliales, Aleurismaceae), Gary L. Bradley

Loma Linda University Electronic Theses, Dissertations & Projects

The questions posed in this research concerned both the comparison of the nitrogen nutrition between Emmonsia parva and Emmonsia crescens and the comparative nitrogen utilization within the species. This fungus is a parasite with a rather uncomplicated life-cycle. Thus it lends itself well to study of the host-parasite relationship at the molecular level. This research contributes toward that long-range goal.

Five replicate floating cultures of each species were grown in 125 ml Erlenmeyer flasks containing a chemically defined basal medium plus one of the 29 nitrogen sources tested. Utilization of a particular source was determined by dry weight. The results …

Mandibular And Alveolar Growth In Dog Following Infusion Of 5-Fluorouricil, Richard D. Pfeiffer

Loma Linda University Electronic Theses, Dissertations & Projects

The action of a chemotherapeutic agent as a tool in studying its effect upon a primary growth center, the mandibular condyle, was investigated. So far as can be ascertained, no studies have been reported where these growth sites have been eliminated or modified by the use of chemotherapeutic growth inhibitors.

Observation of mandibular and alveolar growth following the infusion into the left external carotid artery of a cancer chemotherapeutic agent, 5-Fluorouricil (Roach-Hoffman), was noted. Comparisons were made between the infused and the uninfused sides of the mandible observing gross growth changes.

Four dogs, aged 75 days, were infused with varying …

Tumor Production In The Hamster After Oral Inoculation Of Polyoma Virus, Douglas Jonathan Wear

Loma Linda University Electronic Theses, Dissertations & Projects

One-half of the newborn hamsters orally inoculated with polyoma virus developed tumors within the interval of observation, whereas all of the newborn hamsters inoculated by the more conventional routes of virus inoculation (the subcutaneous and the intraperitoneal routes) eventually developed tumors. The death rate in the orally infected hamsters was less than that of either of the other two inoculated groups, and the age at occurrence of the first death in this group of hamsters was several days later than in the other two groups. In the course of tumor formation in the heart, lungs, liver, and kidney of the …

Carbon Dioxide Fixation In Schistosoma Mansoni, Clint Earl Carter

Loma Linda University Electronic Theses, Dissertations & Projects

Adults of the blood fluke Schistosoma mansoni were perfused from the hepatic portal system of CF1 female mice sixty to seventy days post infection. The worms were then incubated in Eagle’s minimal essential medium with glutamate and 0.03 mg/100 ml of nonlabelled aspartic acid. To this medium was added 10 μc of either NaH¹⁴0₃, glucose-UC¹⁴ or aspartate-4-C¹⁴. The worms were found to fix carbon from the NaH¹⁴0₃ and to incorporate the glucose and aspartate. The amount of activity recovered in five different chemical fractions after two hours incubation was determined …

The Effect Of Schistosoma Mansoni On Free Amino Acid Levels In Mice, Richard D. Tkachuck

Loma Linda University Electronic Theses, Dissertations & Projects

Free amino acid levels in the blood plasma of mice infected with Schistosoma mansoni Sambon, 1907, were measured at 3, 6, and 9 weeks post-infection with an automatic amino acid analyzer. Significant differences between experimental and control animals occurred at all three time periods. At 3 weeks, asparagine, alanine, citrulline, proline, methionine, and threonine levels all were lower in the infected animals. At 6 weeks, four differences were noted. Alpha-amino-n-butyric acid, ornithine, lysine, and histidine all had lower values in infected animals. At 9 weeks there were 12 differences. Tyrosine, phenylalanine, threonine, serine, proline, citrulline, glycine, alanine, valine, isoleucine, and …

Vegetable Entrees In Nitrogen Balance And Obesity Studies, Gloria Tyndall

Loma Linda University Electronic Theses, Dissertations & Projects

The first study was designed to evaluate by the nitrogen balance method the protein quality of a pure-vegetarian diet containing about 6 grams of nitrogen per day. The group as a whole maintained nitrogen equilibrium the average being - 0.11 grams of nitrogen per day. Two subjects were not in nitrogen balance, however, factors other than diet may have contributed to these results and are discussed in the thesis. Hemoglobin, serum cholesterol and total serum proteins did not change significantly during the study. The average true digestibility of 5 of the subjects was 85 percent. It was concluded that this …

Studies Of Sodium-22 Distribution During Hypothermia In Rattus Rattus, David N. Danforth Jr.

Biology ETDs

The response of regional circulation to reduced body temperature was studied in the white laboratory rat Rattus rattus, using injected ²²Na as a tracer. Observations made on equilibration of plasma and tissue radiosodium, in normo- and hypothermic animals, provided evidence as to possible mechanisms responsible for transport of sodium at this interface. Evidence is also presented as to disposition of sodium in tissues during the first biological half-life.

Circulation to the peritoneal cavity is reduced to 50%, and to skin and bone approximately 10% and 25% of normothermic values respectively at body temperatures of 16-18 C. The appearance of …

The Ecology Of The Western Spotted Frog, Rana Pretiosa Pretiosa, Baird And Girard: A Life History Study, Ronald Ladell Morris

Theses and Dissertations

Observations and collections on the breeding biology and life history of Rana pretiosa pretiosa Baird and Girard have been made in central Utah from 1962 to 1967. The frogs' activities were followed from their spring emergence untril the tadpoles metamorphosed and hibernated in the fall. Collections and observations were made at regular intervals through the entire period of summer activity. Data were gathered at the ponds and samples of the life history stages were taken to the laboratory where they were analyzed and studied. Emergence is normally during the middle of March. The males precede the larger females by three …
