The Use Of Different Embryos In Studying The Development Of Man, John C. Bartone

Journal of the Minnesota Academy of Science

The early development of man (embryology) is generally taught with the use of embryos of different animals. Human embryos are seldom used. This is true in the medical, graduate and undergraduate curricula. The primary reason for this utilitarian approach is simply because human embryos are generally not obtainable in numbers sufficient for the wide distribution necessary for all colleges and universities. Another reason is that fairly good substitutes are available to exhibit the early embryological stages of development of man. Some of these substitutes are embryos of the chick, frog and pig.

Acute Effects Of Acetazoleamide (Diamox) Administration On Pulmonary Carbon Dioxide Exchange In Humans, George G. Burton

Loma Linda University Electronic Theses, Dissertations & Projects

Previous studies dealing with the effects of oral acetazoleamide (Diamox^R) administration in humans have yielded equivocal results. Effects of intravenous administration of this agent, a potent carbonic anhydrase inhibitor, have not been studied until recently. It is postulated that difficulty in interpreting these results has risen in part from failure to evaluate given parameters in terms of drug concentrations or degree of carbonic anhydrase inhibition achieved.

These concentrations were ascertained throughout the present work of this Thesis, which deals with the effects of both small and large doses of this agent upon ventilatory parameters in man.

In these …

The Pacemaker Function Of The Small Intestine, Robert W. Hasselbrack

Loma Linda University Electronic Theses, Dissertations & Projects

New evidence is presented to clarify to some extent the significance of the gradient of rhythmicity in the small intestine of the unanesthetized dog. The gradient of rhythmicity was studied on five dogs prepared with duodenal fistulas. Rhythmic contractions were recorded from the small intestine by a small rubber balloon. The gradient of rhythmicity was found to decrease in a stepwise manner as the distance from the pylorus is increased. Roughly, the rhythmic contractions were found to be 18 to 19 per minute in the duodenum and 14 to 15 per minute in the ileum. In the terminal ileum there …

Famous Sheep Breeds. 2. The Corriedale, J A. Mallett

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

THE Corriedale sheep is a breed which has achieved widespread popularity throughout the world as a dual-purpose animal.

It was evolved by New Zealand breeders who—not fully satisfied with the performance of either the Merino or the British longwool sheep under their conditions—sought an animal which would combine the superlative wool-producing properties, and outstanding foraging ability of the Merino with the better meat production and better mothering qualities of the British sheep.

Autumn V Spring Shearing, W L. Mcgarry, I. K. Stott

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

IN the agricultural areas of this State it is customary to shear in the late winter or spring, usually some time between July and September.

In an experiment conducted at Muresk Agricultural College during the past two years it has been shown that shearing in autumn (March) has resulted in more wool being produced with higher returns than when shearing at the conventional time.

Artificial Respiration During The Apnea Of Cerebral Trauma, Thorvald W. Christiansen

Loma Linda University Electronic Theses, Dissertations & Projects

Cerebral concussion often results in profound respiratory depression. The earlier workers in the field of experimental concussion concluded that artificial respiration could be a life preserving procedure in 4 many instances. More recently, however, it has been held that this form of resuscitation is of little or no value.

Because of this conflict in viewpoint and inasmuch as the latter interpretation was made as a result of studies that were not primarily directed towards assessing the worth of artificial respiration during the apnea of experimentally induced concussion, this study was planned with the hope of resolving the differences of opinion. …

The Visceral To Skin Temperature Gradient In Restraint Hypothermia, Glenn L. Foster

Loma Linda University Electronic Theses, Dissertations & Projects

[Abstract Not Included]

Summary: The effects of restraint on skin, subcutaneous, and deep visceral temperatures of rats exposed to environmental temperatures of 0°C, 8°C, 16°C, and 28°C are determined. The temperature gradients of restrained and unrestrained rats at 0°G are compared.

From the data presented, it is felt that one factor in the thermolability of restrained animals is an increased heat loss. There is also evidence suggesting a decreased metabolic rate, the chemical nature of which is unknown Which of these two factors plays the greater role is yet to be determined.

Distributional Studies Of Parasitic Arthropods In Utah Determined As Actual And Potential Vectors Of Rocky Mountain Spotted Fever And Plague: With Notes On Vector-Host Relationships, D Elden Beck

Brigham Young University Science Bulletin, Biological Series

Through the courtesy of the National Institutes of Health, Grants and Fellowships Division, a project was established at Brigham Young University to study the distribution and host relationships of vectors for Rocky Mountain spotted fever and plague in the state of Utah.

Rocky Mountain Spotted Fever
Of the four capable vectors listed as present in the United States, Dermacentor andersoni and Haemaphysalis leporis palustris are found in Utah. Listed for Utah as potential (experimental) vectors are Dermacentor parumapertus, Dermacentor albipictus, Rhipicephalis sanguineus and Ornithodoros parkeri. Of the potential vectors D. parumapertus is the only species having extensive distribution in Utah. …

An Improved Technique For The Demonstration Of Tissue Lipids, Bryan G. Hoerl

Master's Theses (1922-2009) Access restricted to Marquette Campus

Progress in science frequently depends upon proper tools to demonstrate, enhance, integrate, substantiate or refute contentions. Among the means that make possible the advance of biological science is histological technique. Improved microscopic procedures result from a constant refining process and the search for new methods. To merit the adjective "improved" a new or refined technique must display a superiority to similarly employed processes. Such superiority might be shown by its speed, economy, practicality, ease or faithfulness of reproduction, or same other attribute. This paper portends to present an improved technique for the demonstration of tissue lipids .

Some Factors Which May Influence Survival Of Game Farm-Reared Pheasants After Release Into The Wild, Taylor F. Cottle

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was undertaken in an attempt to determine some of the factors which may influence the survival of Utah game farm-reared pheasants following their release into the wild. The survival of these birds is below the desired level after they are released, as is indicated by the low percentage taken by the sportsmen during the hunting season. In recent years the return from released game farm-reared pheasants is about 7 to 8 percent.¹ Consequently, if survival rate of these birds could be increased, more birds would be available to supplement the wild stock. Also, an increase in the …
