Effects Of Diet And Stress On Gastric Lesions In Albino Rats And Guinea Pigs, Naomi Mckenzie

Loma Linda University Electronic Theses, Dissertations & Projects

Studies were conducted to (1) investigate whether any protective factor is present in fresh water-cured olives or fresh cabbage as compared with the heated supplements against stress-induced gastric lesions in rats maintained on a nutritionally adequate diet for six weeks, (2) determine the relative protective factor in water-cured olives as compared with cabbage, (3) study the effect of black pepper in combination with fresh cabbage and olives and heated cabbage and olives in rats that were fed the same nutritionally adequate diet, and (4) investigate the effects of the same dietary components—cabbage and olives--on histamine- induced gastric lesions in guinea …

The Ciliary Currents Associated With Feeding, Digestion, And Sediment Removal In Adula (Botula) Falcata Gould 1851 (Bivalvia, Mytilidae), Peter Vaughn Fankboner

University of the Pacific Theses and Dissertations

Adula (Botula) falcata Gould (Soot-Ryen, 1955) lives commonly as a byssally attached rock borer in soft mudstone reefs at Bolinas and Moss Beach, California (Figure 1). Keen (1963) reports that Adula falcata has been collected from the intertidal to a depth of ten fathoms. Its distribution is from Coos Bay, Oregon, to Cape San Lucas, Lower California (Hertlein and Strong, 1946), and collection data indicate a range as far south as Peru (Soot-Ryen, 1955).

While is possesses the protective advantage of living cryptically, Adula falcata is subjected to an environmental stress not faced by epifaunal mytillids; namely, it must function …

Three Beef Raising Systems For Butterfat Producing Properties, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

THREE-QUARTERS of the calves born in autumn on butterfat farms are not required as milking replacements and are thus available for beef production or immediate sale, at about $20 a head.

The profit from selling beef must be compared with that from selling excess calves off their mothers.

Such a comparison is being made by Department of Agriculture Beef Research Officer D. J. Barker in a series of trials at Bramley Research Station, Margaret River.

Sheep : Experimental Basis For Urea Feeding Recommendations, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

Recent scientific reviews have concluded that in spite of the great number of experimental observations recorded throughout the world there is no evidence yet to prove that urea can be used profitably for sheep on low quality roughages in genuine grazing conditions.

An experiment is in progress at Merredin Research Station this season, especially designed to demonstrate a response to urea by sheep grazing wheat stubbles, if such a response is possible.

The Making Of A New Pasture Variety, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

FARMERS who attend field days at Department of Agriculture research stations are reasonably familiar with the procedure for producing a new cereal variety. It involves a painstaking and tedious process of crossing, followed by many years of segregation, selection and testing for yield, disease resistance, and other characters.

Although there are many pitfalls, the procedure for the creation of a new cereal variety is at least fairly well systematised.

Until recently the making of a new pasture variety was far from a systematic undertaking.

Urea Mixture Formulations, H E. Fels

Journal of the Department of Agriculture, Western Australia, Series 4

This experiment was done once the experiment above (Urea or Grain Supplements for Stubble) had shown definite but uneconomic responses to a particular mixture of urea, molasses and minerals. The aim was to find whether the response depended on the content of various portions of the mixture, and whether the response to the "shotgun" lick could be explained by the presence of salt, sulphate or cobalt.

Reproductive Biology Of Thais Emarginata (Deshayes, 1839) And Thais Canaliculata (Dulcos, 1832), Roy Seamands Houston

University of the Pacific Theses and Dissertations

Thais emarginata (Deshayes, 1839) and Thais canaliculata (Dulcos, 1832), are two common Pacific coast gastropods (Family: Muricidae). T. emarginata is found in semi-protected rocky areas from Alaska to Baja California, while T. canaliaulata occurs in quiet bays from Alaska to Monterey Bay, California (Ricketts and Calvin, 1966). Both species occur on rocks and jetties where they can be seen feeding upon barnacles and young mussels. Despite the abundance of these species their reproductive biology has not been examined.

In the present study, the following aspects of the reproductive biology of T. emarginata and T. canalieulata are presented: Relationship of gonadal …

Studies On An Antibiotic-Producing Strain Of Bacillus Megaterium X, Kishori Madhukar Chaubal

University of the Pacific Theses and Dissertations

On July 10, 1968, while observing the effects of ultra-violet light on a plate culture of Sarcino lutea, o contaminant was found growing in the form of a colony surrounded by a clear zone of inhibition where S. lutea had failed to grow. A smear from this contaminant colony was found to contain a Gram positive, chain-ond spore-forming bacillus. The organism was isolated and its antagonism against S. lutea was reshocked. Preliminary investigation of its activity against other bacteria indicated that this activity was directed against 5. lutea only. I was decided to continue the investigations with two aims in …

Pneumatosis Cystoides Intestinalis: The Report Of A Case Associated With Severe Pulmonary Disease And Chronic Lymphocytic Leukemia, Russell J. Crider, Philip Bentlif

Henry Ford Hospital Medical Journal

Pneumatosis cystoides intestinalis is discussed with emphasis on its clinical, radiologic, sigmoidoscopic, surgical and pathological characteristics. The four theories of the etiology of P.Cl. are neoplastic, infectious, nutritional, and mechanical. These theories are discussed, and a case of P.C.I, associated with severe pulmonary disease and chronic lymphocytic leukemia is presented to lend support to the mechanical theory.

Effects Of Metepa On Gametogenesis And Embryogenesis In The Large Milkweed Bug Oncopeltus Fasciatus (Dallas), Donald E. Lawson, Harold J. Ball

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Considerable research is currently being directed toward discovering means of controlling insects other than by applying insecticides. There are several promising concepts of control which minimize the use of insecticides and one of these is the use of sterilizing techniques. Some emphasis is currently being placed on the development of chemosterilant techniques. Many of the studies have been concerned with the screening of potentially active chemicals, whereas other research has dealt with the efficacy of field application. The more basic work has been accomplished through the participation of several disciplines. The purpose of this study was to characterize the effects …

Kinetic Studies Of The Cell Elongation Phenomenon In Etiolated Pisum Stem Segments, Grant M. Barkley

Masters Theses

The short-term growth response of etiolated pea stem segments (Pisum sativum L., var. Alaska) was investigated using a high-resolution growth recording device. The immediate effect of treatment with indoleacetic acid (IAA) is an inhibition of growth. This inhibition lasts about 10 minutes and then the rate of elongation rises abruptly to a new steady rate about 4 times the rate of elongation before auxin treatment. This rapid steady rate of elongation, however, continues for only about 22 minutes before declining suddenly to a lower steady rate of growth about 2 times the rate of elongation before the addition of auxin. …

A Biological Investigation On Plethodon Larselli, Charles Oliver Holmes

All Master's Theses

The purpose of this study is to increase the presently-lacking biological knowledge of P. larselli. A study was made, therefore, on this species relative to its geographical distribution, habitat, dehydration and rehydration rates, response to induction with varying concentrations of a gonadotropic hormone, and blood serum analysis by cellulose acetate electrophoresis. In addition, the findings of this investigation will help elucidate the relationship between P. larselli and P. vehiculum.

Food Habits Of Dicamptodon Ensatus And Associated Fish Species Of Maratta Creek, Washington, Authur L. Antonelli

All Master's Theses

Three cold-blooded vertebrates, Dicamptodon ensatus, Cottus tenuis, and Salmo gairdneri were investigated as to food habits for a period of one year. The existence of competition between these animals for food was determined by means of stomach analysis. The results were compared relative to each vertebrate and the bottom fauna procurred from the stream. It was shown that the food habits of D. ensatus and S. gairdneri were diverse enough to warrant partial exclusion on the basis of food. C. tenuis demonstrated selectivity and was shown to be under competitive stress from the other two species.

The Effects Of Herbicides On Three Soil Inhabiting Blue Green Algal Species, Lee C. Darlington

All Master's Theses

The Effect Of Exercise On Metabolic Rate With Time In Overweight And Normal Weight Subjects, Roberta Jewell Keswick

Loma Linda University Electronic Theses, Dissertations & Projects

Previous studies in the Lome Linda University laboratory showed that obese subjects on an exercise program lost approximately one pound more per week as compared to a non-exercise group. Energy expenditure calculations of the exercise did not account for the total caloric deficit required to lose the additional pound. The present study was designed to investigate changes in BMR and metabolic rate with time for normal weight and overweight subjects involved in a practical exercise program. The relationship of changes in BMR and metabolic rate in coping with the problems of obesity were also studied.

Fifteen subjects, eight overweight and …

A Study Of Folic Acid Dependent Reactions In Bovine Brain, Dillard Spencer Broderick

Theses and Dissertations

The enzymatic interconversion of serine to glycine and N5, N10-methylene tetrahydrofolate to N5 -methyl tetrahydrofolate have been studied in a cell-free system derived from bovine brain. A partial purification of serine transhydroxymethylase and N5, N10 -methylene tetrahydrofolate reductase has been achieved by ammonium sulfate fractionation, protamine sulfate fraction, and by various column chromatography procedures. The two enzymes studied catalyze sequentially the reductive transfer of the hydroxymethyl group of serine to the N5 position of tetrahydrofolate forming N5 -methyl tetrahydrofolate. The products of these reactions were assayed by the incorporation of C14 from a one-carbon precursor i.e., L-beta-(C14)-serine, or N5 -methyl …

Comparative Effects Of Carbon Dioxide On Coccidian Oocysts From Five Different Host Species, Thomas David Bunch

Theses and Dissertations

Excystation, as applied to the coccidia, is the process by which sporozoites are released from sporocysts and oocysts. Although this process has long been a subject of interest and study, there still remains considerable disagreement among investigators as to the mechanism by which the process occurs and the factors which are involved.

The Identification Of A Germination Factor For Basidiospores Of Psilocybe Mutans, Neal K. Van Alfen

Theses and Dissertations

Basidiospores of the Basidiomycete Psilocybe mutans have been found to germinate only in the presence of water extracts of animal dung. The chemical nature of the factor present in the dung that induces germination is not known, nor has it ever been isolated· Experiments showed that extracts of bile salts cause the basidiospores to germinate, indicating that since bile salts are found in dung, they may be the factor which stimulates the spores to germinate. Investigations of the properties of the factor in dung show that the factor has solubility properties that are similar to those of the bile acids. …
