The Effect Of Renal Artery Constriction On The Course Of Pregnancy In The Laboratory Rat, Julie Jones Medlin

Masters Theses

Introduction

Goldblatt and his associates (1934) were the first to show that persistent arterial hypertension could be produced by renal ischemia. They produced renal ischemia by two procedures which involved reduction of the blood supply to one or both kidneys by means of adjustable silver clamps and removal of the non-ischemic kidney where only one kidney was made ischemic. In one procedure the clamps were placed directly on the renal arteries. The second procedure produced renal ischemia indirectly by constriction of the abdominal aorta above and below the site of the origin of both renal arteries (1939). The adjustable silver …

An Investigation Of The Influence Of The Suprapharyngeal Ganglion Upon Oxygen Consumption Of Resting Lumbrious Terrestris, William E. Elzinga

Masters Theses

Introduction

Because cephalization and centralization of the earthworm are more pronounced than in less complex forms, it is a relatively simple operation to remove a portion of the central nervous system to investigate its functions. However, the extripation of various parts of the central nervous system of the earthworm has been the subject of only a few research papers. It is the purpose of this study to investigate the influence of extripation of the suprapharyngeal ganglia on the oxygen uptake of the resting earthworm, Lumbricus terrestris.

Of the studies concerned with the influence of extirpation of some parts of the …

Comparative Ecology Of Three Species Of New Mexican Garter Snakes (Genus Thamnophis), Eugene D. Fleharty

Biology ETDs

The ecological literature states that closely related species that occur in the same ecological area undergo competition until one out-competes the other (or until each becomes restricted to a very specific niche). Darwin (1859) stated that species of the same or related genera which had nearly the same structure and habits undergo severe competition. More recently this view has been restated in what is known as "Gause's Law" (Gause 1934; Gilbert, Reynoldson, and Hobart 1952). Bagenal (1951) emphasized the difficulties in determining what is meant by the same habitat or the same community. Actually, as Bagenal (Ibid.) pointed out, because …

Measurement Of Cardiac Output In Man, At Rest And During Exercise, By An Indirect Fick Co2 Method, Orlando Thomas Garza

Biology ETDs

In the field of medical science it is necessary to understand the life processes; their normal levels, responses and mechanisms before interpretation of changes caused by disease or stress can be made with any degree of accuracy. This paper deals with a method of obtaining cardiac output values, and is not meant to be a discussion of the highly involved mechanics controlling the cardiac output., but a cursory review of these mechanics is warranted.

Ectoparasites Of Rabbits Collected In Grant County, New Mexico, Paul Henry Rodriguez

Biology ETDs

Nine obligate ectoparasites were taken from 28 Sylvilagus auduboni and 14 Lepus californicus collected in Grant County, New Mexico, from April 15, 1962, to December 24, 1962.

Cediopsylla inaeqaulis inaequalis and Hoplosyllus glacialis affinis, which may be important in the epidemiology of plague, were found to be primarily restricted to S. auduboni. Echidnophaga gallinacea, which is usually found on birds, Pulex irritans, and Meringis dipodomys, which is common on wild rodents, proved to be incidental ectoparasites of this species of rabbit. Thirteen H. glacialis affinis and five E. gallinacea were taken from six L. californicus.

The continental rabbit …

Attempt To Determine The Pattern Of Chromosomal Inheritance In The Intermediate Iris, Theodore Kellogg

Senior Scholar Papers

Intermediate iris containing 44 chromosomes have a low rate of fertility. This paper is an attempt to determine the reasons for this low fertility through a study of the chromosomal inhertiance of two intermediate iris that have been successfully hybridized. There are no literary records showing that the results of crossing two chromosome intermediate iris, so most of this paper is a report of lab work.

Factors Influencing Elk Distribution On Willow Creek Summer Range, Utah, Duane Eldro Jeffery

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study is aimed at gaining a better understanding of the factors responsible for the distribution of elk on summer range, and an analysis of characteristics of preferred habitat. Such knowledge should prove of value in elk management, both in better managing elk herds themselves, and in coordinating their needs with those of other land uses.

Some Aspects Of The Relationship Between Two North American Whiptail Lizards, John W. Wright

Biology ETDs

The present investigation was undertaken in an attempt to clarify further the taxonomic relationship between Cnemidophorus octolineatus (=C. inornatus) Baird and C. Velox Springer. At various times these two have been treated as species, subspecies, or synonyms, and have been re-described at one time or another as new species or subspecies.

Systematic Revisions Of The Genera Pseudoficimia, Gyalopion, And Ficimia (Serpentes: Colubridae)., Laurence M. Hardy

Biology ETDs

Originally, this systematic problem was concerned with the genera Ficimia Gray, Gyalopion Cope, fseudoficimia Bocourt, Conopsis Gunther, am Toluca Kennicott.

The five genera represent a problem that could include intergeneric studies of Ficimia, Gyalopion, and Pseudoficima on the one hand and Toluca and Conopsis on the other, interspecific studies of each genus, and, in some well-represented forms, intraspecific studies based on large samples from single localities.

Comparative Morphology Of The Two Species Of Grasshopper Mice, Genus Onychomys, In New Mexico, Gerald L. Traut

Biology ETDs

Inasmuch as individual specimens of the cricetid genus Onychomys Baird are frequently difficult to identify to species even using the commonly used key characters, a total of 376 grasshopper mice was examined to determine how and to what extent the two species, O. leucogaster and O. torridus, differ from each other in New Mexico.

To this end, 31 measurements (cranial, skeletal, and hair) and ratios were ascertained for each individual. The nearly 12,000 figures were summarized by constructing 161 modified Dice-Lerass diagrams.

Study Of Proteinuria: Isolation Of Proteins From The Nephrotic Syndrome, Merrill C. Raikes

Senior Scholar Papers

One of the most puzzling phenomena of abnormal renal physiology is the occurrence of the nephrotic syndrome. The syndrome has been defined by a collection of clinical and pathological symptoms, but there is no correlation between the clinical and pathological symptoms nor is the etiology of the syndrome known. Proteinuria is probably the most distinguishing feature in the nephrotic syndrome, and there are two possible explanations for its occurrence: (1) the excessive amounts of protein found in nephrotic urine could be due to an increased basement membrane permeability in the glomerulus of the kidney or (2) dysproteinemia. An attempt has …

Development Of Circadian Sleep-Wakefulness Rhythm In A Healthy Boy Gauged By Circadian Quotients, Ellen Reeker, Michael Diffley

Journal of the Minnesota Academy of Science

The circadian quotient, briefly CQ, serves to estimate the prominence of a rhythm with a period of about 24 hours. The CQ may be computed from so-called variance spectrum analysis, among other procedures ( 1) . Computational details and some applications have been discussed earlier (1 , 2). We wish to illustrate herein the use of the CQ for gauging the development of a circadian sleep-wakefulness rhythm in the senior author's first-born child, FAR, also documented in general terms, elsewhere ( 3).

Apparent Effects Of Refrigeration On The Rate Of Embryonic Development Of Mayfly (Hexagenia Limbata) Eggs, Roger Flattum

Journal of the Minnesota Academy of Science

Hunt (19 5 3) states that temperature is an important factor influencing the rate of embryonic development of Hexagenia (mayfly) eggs. Pasvogel (1962) has reported that 46 days is the time limit Hexagenia eggs can remain dormant at temperatures slightly above freezing. It was the object of this investigation to continue this line of research and to determine the effects of temperature on the embryonic development of Hexagenia limbata eggs.

Comparative Anatomy And Biology Of Two Species Of The Asteroid Genus Pisaster, Norman William Mayer

University of the Pacific Theses and Dissertations

Interest in the endemic Pisaster was first aroused by the great variation of external color in Pisaster ochraceus. This in turn led to observations of the diversity of the spinous patterns of this sea star. Following the suggestion of Dr. Jool D. hedgepeth it was decided to make an extensive comparison of the common species of Pisaster.

Detailed comparison between Pisaster brevispinus and Pisaster ochraceus have been made only by Fisher (1930) and Verrill (1914). Both of these investigators restricted their observations largely to the endoskeleton and its calcareous protuberances. In addition to analyzing the work of Fisher, an attempt …

Biology ETDs

Seven hundred and forty-four specimens of the Rio Grande mountain sucker collected in Jemez Creek, a tributary in the Rio Grande system, were measured, sexed and aged. Both length-frequency and scale methods were used to determine the age of these specimens. The oldest males were six years of age, at which time averaged 134 mm in standard length. The oldest females were seven years of age, and average 159 mm in standard length. First spawning for both males and females occurred in the spring after they had completed three full years of life. The onset of senescence, expressed as a …

On The Use Of Tris (Hydroxymethyl) Aminomethane As A Diluent In Quantitative Analyses Of Soil Bacteria, Barry L. Keller

Masters Theses

Introduction

Many investigations have been conducted in the field of soil microbiology during the past.six decades. Most notable among the contributors is S. A. Waksman whose voluminous works have established many of the procedures used in microbial analyses of soil. Yet, the one fact that is foremost to any reviewer of the literature covering this field is that no standardization of techniques for soil analyses exists. The following presentation deals with one method used to estimate the number of bacteria and actinomycetes in soil.

The use of Tris(hydroxymethyl)aminomethane (hereafter referred to as "Tris") is not new. Tris currently is used …

A Histomorphological Comparison Of The Urinary Systems In The Serranid Fishes, Roccus Sexatilis (Walbaum) And Roccus Americanus (Gmelin), Irwin Beitch

Master's Theses

The urinary systems of Roccus saxatilis (Walbaum) and Roccus Americanus (Gmelin) were studied to check the validity of the monogeneric classification and to examine the osmoregulatory mechanism that allows the species to survive in environments of various salinities. The gross anatomy of the urinary systems of 13 R saxatilis and 12 R. americanus showed a number of similarities to exist, e.g. the general mesonephric form and size, uretal position and length, and the renal venous system. The head kidney, a hemopoietic organ, was larger in R. ­saxatilis than in R. americanus. Histological comparisons were made of H and E serial …

Some Effects Of Ph, Temperature And Light On The Production Of Zoosporagia In Saprolegnia Parasitica Coker, Philip C. Lee

Master's Theses

Pure cultures of Saprolegnia parasitica Coker were grown under varied conditions of temperature, pH, and light conditions. In liquid medium colonies were spherical with a zonal effect in the distribution of zoosporangia.

Near the limiting extremes of pH and temperature, beaded hyphal tips were found in place of normal sporangia. Teorell Universal buffer in the sporulation water inhibited production of sporangia. The pH minimum was 4.0 - 4.1, optimum 6.3 - 7.4, and maximum 8.o - 8.3. The maximum number of sporangia was produced at 15 C. Between 3.4 and 5 C , a delay in sporulation was noted and …

An Investigation Of The Genetic Basis Of Alcoholism, Daniel F. Malamud

Masters Theses

Introduction

Alcoholism: The Disease

"Alcoholism is a chronic disease manifested by repeated implicative drinking so as to cause injury to the drinker's health or to his social or economic functioning" (53). Such a definition of alcoholism points to the disease concept which went unrecognized until recent years. In addition to its medical implications, alcoholism has been the subject of considerable writing and research by academicians in such diverse fields as sociology, psychology, physiology, psychiatry, theology, and law.

At the outset it should be noted that the writer is aware of the arguments and opinions expressed by the advocates of the …

A Floristic Study Of The Basidiomycetes Of The Sandia Mountains, New Mexico, Horace R. Simms

Biology ETDs

The basidiomycete flora of the Sandia Mountains has never really been investigated before. At best this survey can serve only as a rather spotty general sketch of fungi in the area. But at least it is a beginning, and one which is not slanted just at the pathological aspects. It is my hope that such information as has been uncovered will help in future ecological and taxonomic investigations of the fungi of these mountains.

A Comparison Of Intestinal Protozoa Among Peromyscus And Other Small Rodents Of Bernalillo County, New Mexico, Raymond C. Bowen

Age And Growth Of The Longfin Dace, Agosia Chrysogaster Girard, John Kristian Winther

Biology ETDs

This is the first study to determine the age and growth of the longfin dace, Agosia chrsogaster Girard. During March, June, and October, 1961, 8,568 dace were collected from the Mimbres, San Francisco River and one of the Mimbres River indicate that Agosia lives just over one year. Estimates of age based on the examination of scales from a stratified subsample of 255 fish appear to agree with length-frequency estimates. The position of a check near the outer margin of scales established the formation of a winter check in March. Two or more checks appear to be formed each year. …

An Annotated Checklist Of The Bats Of Bernalillo County, New Mexico, Frances Veronica Sheppard

Biology ETDs

In 1960-61, Bernalillo County, New Mexico, was surveyed for bats. The purpose of this survey was to determine what kinds of bats occur in the county and to collect natural history data on these bats. Bats were obtained by cave and roost searching and by mist-netting and shooting over ponds, streams, and tanks. For all bats collected, standard museum study skins and skulls as well as alcoholic carcasses are preserved in the Museum of Southwestern Biology at the University of New Mexico.

Rapid Identification Of Streptococcal Infections Using Fluorescent Antibody Techniques, James H. Meadows

Biology ETDs

The use of fluorescent microscopy coupled with immunological techniques offer new methods for the demonstration of antigen-antibody reactions. The adaptation of these techniques to grouping of beta hemolytic streptococci makes feasible their further adaptation toward identification of group A streptococci in clinical material. Commercially available labeled antibodies against group A beta hemolytic streptococci were obtained for use in this study. A method for the determination of labeled antisera specificity is proposed and a technique for absorbing out any heterologous reacting antibody is described. Using this commercial labeled antisera, subsequent to specificity studies plus absorption if necessary, adaptations of basic fluorescent …
