A Study Of The Renal Vascular Supply In The Domestic Cat, Elizabeth Rosen

Bachelors’ Theses

Studies on the normal and abnormal vascularization of the renal vessels in the domestic cat (felis domestica) indicate the frequency of anomalies that occur, but in most of the studies it is the inferior vena cava that is most often recorded. Among the occasional references to several renal veins or arteries we have Huntington and McClure, Elmer Butler, Gaylord Bates, William Darrach, and C.H. Fortune. Yet no study seems to have been made of individuals of any particular class. A superficial observation seems to indicate a large number of cats used in the laboratory had multiple renal veins. Hence a …

Some Technique Methods For Preparing Slides Of The Paramecium, Irene Padley

Bachelors’ Theses

Du Jardin (1835) was probably the first to recognize in protozoa, living substance. To this substance, he applied the word sarcode. In 1861, Max Schultze expressed the idea that sarcode and protoplasm are the same thing.

A Study Of The Respiratory System Of The Sparrow (Passer Domesticus), Ben Peter Arnowitz

Bachelors’ Theses

The respiratory mechanisms of birds, unlike that of mammals, are definitely adapted to the function of flight. Because of this added adaptation, we should expect, therefore, some morphological and perhaps even embryological, physiological, and histological differences. An example of a morphological difference between birds and mammals is the intricate system of air-sacs that are present in birds. This remarkable feature is probably the reason why birds are able to fly as they do.

In this thesis the writer has used the sparrow (Passer domesticus) for the basis of his experiments. This particular bird was chosen in preference to …

A Study Of The Digestive System In The Sparrow (Passer Domesticus), Henry Joseph Wisniewski

Bachelors’ Theses

The digestive tube proper of the Sparrow beings with the Oesophagus. This is a soft tubular organ which serves to convey food rapidly from the pharynx to the stomach. It extends along the median ventral margin of the neck lying dorsal to or to one side of the trachea. Posteriorly, at the base of the neck and shortly in front of the sternum it broadens slightly and gives rise to a dilated region of the oesophagus, namely the Crop, "whose secretion serves to moisten the food or even to initiate digestion." In larger birds as in the pigeon, the crop …

A Study Of The Anatomical Structure Of The 6mm Wall-Eyed Pike, Richard E. Roche

Bachelors’ Theses

The following is a detailed study of the 6 mm Wall-eyed Pike. The organs and organ systems are presented and discussed in the same serial order that they appear in the embryo beginning at the anterior end and proceeding posteriorly. There has apparently been very little work done on the embryology of the Wall-eyed Pile for the literature contains only one article that is even closely related to this problem. In 1890 Reighard made a general study of the development of the Wall-eyed Pike from the time of fertilization to the fully grown adult. He did not, however, make any …

The Incidence Of Trichinella Spiralis In The Diaphragms Of Swine From The Louisville Abattoirs., Stuart Lyle Adams

Electronic Theses and Dissertations

Trichinosis is a disease caused by the parasitic nematode Trichinella spiralis. When meat containing encysted larvae is consumed the cysts are dissolved by the action of the gastric juice in the stomach and the larvae migrate to the intestine where they mature, copulate and give birth to living young within a week of the original infection. The larvae enter the lymph spaces and are carried to the thoracic duct from which they reach the venous circulation and thence the arterial circulation by way of the heart and the pulmonary capillaries. From the arterial blood the larvae enter most of the …

Weight Loss With Carbohydrate-Free Diet In Male Albino Rats, Carroll R. Olson

Bachelors’ Theses

There are a good many clinical facts which suggest that people vary in their susceptibility to dietary deficiency disease. Hence, not all of the crew of a scurvy-ridden ship, come down, nor does everyone in a famine zone develop malnutritional edema.

A Histological Comparison Of The Small Intestine Of The Frog And Man, Eli Getch

Bachelors’ Theses

Without the aid of a microscope, Bichat in 1800 studied tissues of various parts of the body, and, even though he did not make any cellular sketches, his work laid the foundation for histology. Then after the announcement of the cell theory by Schleiden and Schwann in 1839, a new path opened for histological study. Leydig (1864) applied the histology of that day to the lower animals. Cajal (1906) cleared up the complicated relations of the tissues together with a complete investigation of the nervous system.

Resistance To Staphylococcus Aureus In White Rats, Robina B. Langill

Bachelors’ Theses

An investigation of bibliographies shows that staphylococcus aureus in its pathogenic potentialities has been extensively investigated from varied points of view and with frequently conflicting results.

Staphylococcus aureus is most frequently associated with furuncles, wound infection, and minor skin abcesses. Occasionally, however, due to extreme lowered resistance or other conditions not fully understood, staphylococcus causes a septicaemia which is attended by an 80% mortality rate. Post-mortem examinations of the victims of such septicaemia show an extensive invasion of all organs of the body by the bacteria but more particularly a hyperplasia of the lymph nodes, the spleen and thymus, indicating …

A Study Of The Variations In The Growth Of Blue Grama Grass From Seed Produced In Various Sections Of The Great Plains Region, Andrew Riegel

Master's Theses or Doctor of Nursing Practice

During the past 7 years the Great Plains Region, with its "dust bowl", has been the scene of unparalleled activity in the fields of range management and erosion control. The people of this short grass area are extremely conscious of the need for a sound, practical program of conservation that will revegetate the wasted pasture and cultivated land, which will aid materially in preserving the eroding soil. Many problems have arisen as the program of conserving the soil and the vegetation has progressed.

A History Of The Changes In Population Of Certain Mammals In Western Kansas, Floyd L. Carter

Master's Theses or Doctor of Nursing Practice

This particular study has been restricted to certain mammals in western Kansas, including some on which there is little information, and others which observers would be most likely to notice in everyday life. For several years the writer has been vitally interested in the animal life in Kansas. Therefore, when the need for a study of western Kansas mammals was presented to him in the summer of 1936, the problem of this study was selected. It is hoped that this report will suggest to ecologists, historians, and others, further studies, including reasons for the changes here-in shown. What have been …

The Histology Of The Grog's Tongue (Rana Pipiens), Michael William Mille

Bachelors’ Theses

The tongue is generally represented in all vertebrates although it varies widely in the extent to which it is developed. Among the fish it occurs in its most primitive condition. It is called a primary tongue and is merely a fleashy fold of dense connective tissue developed from the floor of the mouth between the hyoid and mandibular arches, the hyoid frequently extending into it and supporting it. It is incapable of motion except as moved by the supporting skeleton for it lacks intrinsic muscles. It is sensory, having both tactile and gustatory functions. It is often papillose, and in …

A Study Of The Structure Of Hair As A Means Of Mammal Identification, Earl R. Oyer

Master's Theses or Doctor of Nursing Practice

The hair of small and medium sized mammals is often found in the stomachs, feces and pellets of predators , for example in the stomachs and feces of coyotes and in the pellets regurgitated by hawks and owls. These pellets produced by hawks and owls and the feces of mammalian predators are the undigested residue of what these animals have eaten. If the hair from these sources can be identified, then much desirable information concerning the food of predators can be obtained. The purpose of this study has been to determine whether or not such identification is possible.

The Spinal Nerves And Spinal Cord Of The Frog, Laverne A. Penn

Bachelors’ Theses

The common grass frog, Rana pipiens as wall as the bull frog, Rana catesbiana have served during many decades as material from which both the student of zoology and the investigator in biological problems have gathered valuable information about the anatomy and physiology of the common systems. Among these systems the central, peripheral, and sympathetic nervous system plays a coordinating role, because of the ramifying nature of its organization. It is the purpose of this thesis to investigate the gross and histological structure of these branches known as spinal nerves. When one inspects the literature on the nervous system of …

A Photographic Study Of The Musculature Of The Dog, Francis Joseph Millen

Bachelors’ Theses

In this thesis the author has endeavored to construct a realistic study of the muscles of the domesticated dog. It has not been his purpose to discover anything new, but rather to make a complete study and outline of the more important muscles of the dog's hind limb.

For references the author has selected two widely known comparative anatomy books. In order that a more complete understanding be had of the muscles themselves, their morphology and physiology, and their orientation, the author also employed the use of several smaller texts of lesser renown. A list of the texts used can …

The Muscles Of The Forelimb Of Canis Familiaris, Charles G. Wilber

Bachelors’ Theses

In the study of the anatomy of the vertebrates, there has been much work done and a large number of the forms have been studied with great thoroughness. Among the domesticated animals this is particularly true. The students of the veterinary sciences have given us a deep insight into the structure and function of the mammalian body. This is most certainly true in the case of the dog. The species Canis familiaris has been used for many years in the studies of physiology and surgery. However, it is also true that a plenitude of literature relative to the anatomy of …

Studies In Breaking The Rest Period Of Grass Plants By Treatments With Potassium Thiocyante And In Stimulating Growth With Artificial Light, Harold R. Shepherd

Master's Theses or Doctor of Nursing Practice

There has developed a need for a practical means of artificially breaking the rest period and of stimulating the growth of grasses so that sods can be procured early in the fall before freezing weather, brought into the greenhouse, and forced early to make an abundant vegetative growth. This need suggested the study of which this paper is the report, namely to discover whether or not the rest period of native grasses can be broken by treatment with potassium thiocyanate and their growth stimulated by artificial light supplemental to winter daylight.

Kidney Of The Frog, Felix Taubman

Bachelors’ Theses

The frog has been used exclusively in both high school and college as the main source of experimental biological and zoological studies. Because it is so easily obtained and so finely adapted to our purposes, we chose it as the specimen upon which to do our thesis work. Much has been done experimentally on the kidneys with the frog. The purpose of this thesis is to present a general view of the external and microscopic anatomy of the frog kidney and with this as a groundwork to present the problems of secretion; whether secretion is carried on by the renal …

The Spleen Of The Frog, Clifford F. Moran

Bachelors’ Theses

Although we of today are living In a relatively advanced state of civilization, there still remains to be solved by man many familiar mysteries. These are found not only in the physical order but in the chemical and biological as well. It seems that the greater strides man takes toward the solution of his difficulties, the more other ones crop up to plague him. With the conquering of such deadly diseases as Diphtheria, Malaria and Scarlet Fever, man once dared to dream about a universe free from sickness. Yet today we find that three others have arisen which are causing …

The Histology Of The Small And Large Intestine Of Rana Pipens, Chester R. Mantey

Bachelors’ Theses

The Frog in past years and in most recent years, has been used to a great extent in the experimental sciences. In the field of physiology, the Frog becomes a great factor for experimental purpose. In addition, the science of pharmacology also makes use of the Frog in determining the actions of many drugs. But, this thesis will endeavor to take up the histology of an organ of Rana pipens, thus limiting the subject matter to this particular phase. It would only be proper at this time, to cite some of the important early workers in Histology. Bichat (1800) …

The Flora Of The Tasco Lake Region, Sheridan County, Kansas, Raymond W. Darland

Master's Theses or Doctor of Nursing Practice

It has been customary in writing theses dealing with taxonomic problems to collect data from an entire county. Having had occasion to collect botanical specimens from the Tasco Lake for work in biology at the Sheridan High School, the wealth of plant life to be found here became apparent. The area ranges from xerophytic forms on the uplands to the hydrophytic forms in the lake and marshes. Many of the latter have never been reported from Western Kansas. Collections in preserving fluid were made of the water forms found and specimens of the landforms were mounted on regulation-sized sheets properly …
