Effect Of Time And Diet On The Immune Status Of Mice Challenged With Herpes-Transformed Cells, Daila S. Gridley

Loma Linda University Electronic Theses, Dissertations & Projects

Human Herpes simplex virus type 2 (HSV 2)-transformed Balb/c mouse cells (H238 cells) are malignant in Balb/c mice. The immune stratus of mice bearing H238 cell-induced tumors was studied and changes in immune response with time and with altered diet of the mice were measured.

In the experiments dealing with the status of immunity with time after tumor cell injection, mice were fed Purina Laboratory Chow (P.L.C.), injected with H238 cells, and sacrificed three to eight weeks post-injection. In the diet experiments, groups of mice were fed either P.L.C. or one of six equicaloric diets, consisting of low or high …

The Effect Of Ergosterol On The Desaturation Of 14c-Labeled Oleic Acid In Tetrahymena, Maynard E. Neville Jr.

Masters Theses

The ciliated protozoan Tetrahymena pyriformis-Strain W desaturated ¹⁴C-labeled fatty acid substrate in both sterol supplemented (ergosterol) and nonsupplemented cultures. Cis-octadecenoic acid (¹⁴C-9-18:1), when added to the medium during the log phase of growth, was incorporated into the cells and also desaturated at the Δ⁶ and Δ¹² positions. The ¹⁴C labeled substrate and products, linoleate (9,12-18:2) or linolenate (6,9,12-18:3) were recovered and separated by silver-nitrate Unisil column chromatography. Initially, recovery of ¹⁴C compounds varied widely when expressed as the percent of total counts per minute recovered from column chromotography, and a variety of …

A Taxonomic And Ecologic Study Of The Riverbottom Forest On St. Mary River, Lee Creek, And Belly River In Southwestern Alberta, Canada, Robert K. Shaw

Great Basin Naturalist

The riverbottom forest community of St. Mary River, Lee Creek, and Belly River in southwestern Alberta, Canada, is a unique ecological entity characterized by poplar species having their major Alberta distribution along these streams. Stands in the community are dominated by three tree species, six shrub species, and nine herb species. Establishment of the community is dependent on climate and substrate; destruction is the result of progressive lateral stream-flow erosion. Soils are sandy loams above gravel, with pH values of 7.7 to 8.0 and soluble salt concentrations of 176 to 458 parts per million. Trees in mature stands averaged 23.0 …

An Electrophysiological Analysis Of The Primary Input To The Cat Prepyriform Cortex, George Maeda

Loma Linda University Electronic Theses, Dissertations & Projects

Properties of the lateral olfactory tract (LOT) action potential and cortical evoked potential (EPSP) were studied using discrete stimuli applied to the tract in acute and chronic preparations. Stimulus response curves for both presynaptic (action) and postsynaptic (EPSP) potentials were sigmoidal and linearly related over the entire range. Simulated action potentials were used to determine the diameter to amplitude relationship, an intermediate step for finding the threshold as a function of tract axon diameter. Our results indicate that threshold is proportional to (diameter) ^-3.4 instead of (diameter) ^-1 as found by others in frog peripheral nerve. Further work is required …

The Streblid Batflies Of Venezuela (Diptera: Streblidae), Rupert L. Wenzel

Brigham Young University Science Bulletin, Biological Series

This study was based on more than 36,000 Venezuelan Streblidae representing ca. 115 species and species complexes in 22 genera, taken from more than 6,800 hats of 95 species. Two new genera are proposed and 45 new species are described. The morphology is briefly discussed and terminology is revised. Collection data are given for each species, together with discussions on variability and host relationships when pertinent. Keys to genera and species arc included, as well as illustrations of most species. Noctiliostrebla dubia (Rudow) and the male of Parastrebla handleyi Wenzel are characterized, and relationships of Speiseria are discussed. New Taxa– …

Effects Of Cariogenic And Noncariogenic Diets On The Concentration Of The Parotid Hormone Releasing Factor In Rat Hypothalami, Melva Joan Brown

Loma Linda University Electronic Theses, Dissertations & Projects

Hypothalamic and cortical extracts from various cariogenically grouped rats which had been maintained on either a Purina diet or a high sucrose diet (HSD) for three months were infused intravenously into 28 days old rats to determine if there was a titer of parotid hormone releasing factor (PRF) capable of facilitating fluid movement (FM) in the teeth. The hypothalamic and cortical extracts obtained from Purina-fed rats with 0-caries and the hypothalamic extracts from BSD-fed rats conclusively demonstrated FM stimulatory ability. Other Purina-fed groups were essentially biologically ineffective, however, extracts from HSD-fed caries groups including scores 11-40 demonstrated extremely potent FM …

Tissue Chromium Levels :|Bautopsy Study In Diabetic And Non-Diabetic American (Pima) Indians, Leslie O. Hansen

Theses and Dissertations

Tissues (liver, spleen, pancreas, and aorta) and hair taken at autopsy from diabetic and non-diabetic southwestern Indians (mainly Pima) were analyzed for chromium (Cr) using flameless atomic absorption spectrophotometry. The Cr levels in both tissues and hair from diabetic subjects were consistently lower than in those from non-diabetic individuals. There were so few individuals in each group that it was not possible to accurately correlate a given tissue either with any other tissues or hair.

Lactate Removal From The Blood Of Trained Distance Runners Following Strenuous Intermittent Exercise, Benjamin F. Timson

Masters Theses

The purpose of the study was to investigate the rate of lactate removal from the blood of trained distance runners, during recovery from maximal intermittent exercise.

Five well trained male subjects (mean VO₂ max of 69.79 ml/kg/min) were selected for the study. Four of the subjects were members of the 1975 Intercollegiate Cross Country team and one was a member of the 1975 Intercollegiate Soccer team at Eastern Illinois University. Each subject received an orientation to the treadmill and a maximum oxygen consumption test prior to the actual test procedure. The test procedure consisted of three separate warm-down periods …

Brigham Young University Science Bulletin, Biological Series

This paper presents the results of a systematic study of mites of the genus Hirstionyssus Fonseca collected from mammals, primarily in Venezuela, but including one collection each from Colombia, Nicaragua, and British Honduras. Previously described species from Panamá and Brazil are reviewed and new distributional records are listed. The known Neotropical fauna of Hirstionyssus mites includes 15 species, 7 of which are described here as new: H. proctolatus n. sp.; H. brachysternum n. sp.; H. dorsolatus n. sp.; H. rhipidomys n. sp.; H, venezuelensis n. sp.; H. brevicalcar n. sp.; and H. parvisoma n. sp. The previously unknown male and …

Spinturnicid Mites Of Venezuela (Acarina: Spinturnicidae), C. Selby Herrin, Vernon J. Tipton

Brigham Young University Science Bulletin, Biological Series

The results of an extensive survey of spinturnicid mites of bats from Venezuela are presented in this paper. Approximately 30,000 bats were collected from a wide variety of life zones and localities. A representative sample was searched for ectoparasites. There are 3 genera of the family Spinturnicidae in Venezuela: Cameronieta, Periglischrus, and Spinturnix. Three previously described species of Cameronieta were found in the Venezuelan collection. Of the 7 species of Spinturnix previously described from the New World, 4 are reported from Venezuela. The genus Periglischrus constitutes by far the most significant segment of the Venezuelan collection. It is represented by …
