The Effect Of Neurosecretions From The Cerebral Ganglia On Blood Glucose Levels In Lumbricus Terrestris, Joan Vanderpol Craig

Masters Theses

Introduction

The presence of neurosecretory cells in the suprapharyngeal ganglia of Lumbricus terrestris has been well established (B. and E. Scharrer, 1937). Since these cells may well be the only source of hormones in this organism (B. Scharrer, 1959), the question arises as to their role in the animal's regulation of metabolism The particular aspect of this problem investigated here concerns the effect of these neurosecretory substances on the blood glucose levels in L. terrestris.

Preliminary studies by this investigator on glucose levels in earthworms revealed that blood samples of approximately 15 microliters could be obtained from each animal and …

The Effects Of Estrogenic And Gonadotrophic Hormones On Normal Levels Of Some Blood Chemical Constituents In The Non-Breeding Female Mallard Duck, Wendell F. Hofman

Masters Theses

Introduction

In past years, a substantial amount of research has centered on the levels of certain blood chemical constituents in birds, particularly in chickens and pigeons. However, little has been recorded concerning the blood chemical constituents of the mallard duck, Anas platyrhynshos. Likewise, the effects of hormones on its blood chemistry, in conjunction with its reproductive system, have been almost totally unexplored. Therefore, this study, conducted from October 14, 1965, to March 3, 1966, had as its purpose the determination of normal quantitative levels of certain blood chemical constituents (the electrolytes--calcium, sodium, potassium; the proteins--albumin and globulin; and lipids) and …

A Comparative Approach Into The Differentiation Of Two Strains Of Staphylococci, Walter D. Hoeksema

Masters Theses

Introduction

The purpose of this investigation was to differentiate Staphylococcus aureus phage type 42D from Staphylococcus epidermidis.

The investigation involved four approaches to this differentiation. The first was a selective screening technique on specific media to point out physical and biochemical characteristics and to demonstrate the presence of specific enzymes. The second was a drug survey which was used to show basic susceptibility and resistance to ten different antibiotics. The third was ultra-violet irradiation which was used to discern susceptibility and resistance to the soft rays of this spectrum segment. The fourth was a chromatographic procedure using labeled carbon which …

Studies On The Effects Of Commercial Detergents On Cucumber And Barley, Marylu Elizabeth Mudd

Masters Theses

Introduction

The fact that large quantities of detergents daily are being added to our water table and the appearance of billows of foam at the shores of many inland bodies of water have caused alarm among biologists and sanitation engineers. However, few observations of the effects of synthetic detergents on living organisms other than bacteria have been recorded.

The purpose of these studies was (1) to determine the effects of several commercial non-biodegradable detergents, Tide, Dreft, and Alconox, and one biodegradable detergent, Living, upon the germination and root elongation of seeds of a monocotyledon, barley (Hordeum vulgare L.) and a …

Sexual Receptivity And Fertility Of Androgen Induced Persistent Estrous Rats, Norman Donald Diebel

Masters Theses

The effect of neonatally administered testosterone propionate (TP) on sexual receptivity and fertility was studied. Dosages of 25 μg and ten μg were used and were administered s.c. in peanut oil on the fifth day of life. Vaginal smears of the animals receiving 25 μg were begun at the age of 61 days and indicated that these animals exhibited modified estrous cycles. By 90 days of age, most of the animals in both dosage groups were in constant vaginal estrus. These prolonged periods of vaginal estrus were often interrupted only by mating.

At 97 days of age 40 females which …

A Study Of The Fluctuation Of Some Blood Chemical Constituents In Relation To The Reproductive Cycle Of The Mallard Duck, Edward H. Decker

Masters Theses

Introduction

The purpose of this study was to determine normal levels of several blood chemical constituents (the mineral sodium, potassium and calcium and the organic substances serum cholesterol and serum albumin) for the female mallard duck (Anas platyrhynchos) and to examine their relationships as a possible index to reproductive development.

Much research has been done on the chemical composition of the avian egg and only those constituents which are of concern in this study will be discussed in detail. According to Romanoff (1949), studies of the chicken egg have shown that only a few mineral elements are present in relative …

A Comparative Study Of The Pollen Morphology Of The Solanaceae (Nightshade Family) Of Michigan, Ronald A. Kudile

Masters Theses

Introduction

The importance of pollen morphology has long been recognized and applied by the paleobotanist (Stone 1963). However, the recent use of pollen as a taxonomic character by systematists has simulated greater interest and research in the area of palynology (Graham 1963).

Several investigators have found pollen to be of significant taxonomic value while others have not. Xavier and Rogers (1963) were able to construct a key to the species of Linum by using characteristics of the pollen alone while Stern (1962) noted interspecific differences in the surface characteristics of pollen grains of all but two species of Dicentra.

This …

Comparative Myology Of The Pectoral Girdle Of Microtus Pennsylvanicus And Pedomys Ochrogaster, Marie Hagerman

Masters Theses

Introduction

The meadow vole Microtus pennsylvanicus (Ord) and the prairie vole, Pedomys ochrogaster (Wagner) are two species of grassland-dwelling, slightly fossorial rodents which are very similar in appearance and general body size and proportions. The objective of this study was to prepare a detailed description of the muscles of the pectoral girdle of M. pennsylvanicus and to compare them to P. ochrogaster. It was hoped that the study might indicate similarities and dissimilarities in the ways in which the two species have adapted to their mode of life and show whether or not they share common adaptations of the pectoral …

An Investigation Of The Influence Of The Suprapharyngeal Ganglia Upon Water Balance And On Osmoregulation In Lumbricus Terrestris, Richard M. Dennany

Masters Theses

Chapter I

Introduction

In the central nervous system of most animals which have been examined some neurons show cytological characteristics of gland cells. These cells are now recognized as a specialized cell type and designated neurosecretory cells.

These neurosecretory cells are capable of elaborating secretory material which is accumulated as granules in the body of the nerve cell and in the axon-endings. They release complex organic substances, neurohormones, which act as hormones and are often liberated into the blood stream (Welsh, 1958). These specialized neurons are capable of receiving impulses from other neurons although their axons do not end in …

Some Effects Of Photoperiodicity On The Temperatures And Weights Of Bobwhites, Bernard J. Cripps

Masters Theses

Introduction

In recent years there have been a number of studies that have dealt with body temperature and body weight variations in gallinaceous birds under various field or controlled conditions. Wilson (1948) studied the reactions of pullets to different environmental temperatures. In a laboratory experiment Bajpai (1962) observed that a change in the cloacal temperature of adult Rhode Island Red males was effected by manipulating the photo-period. In a report on the sexual maturation of Coturnix quail Wilson et al. (1962) discussed several aspects of variation in body weight, which resulted from changes in photo-period. Hamilton (1957) studied the weights …

Relation Between Use Of Lincomycin And Outgrowth Of Yeast, Howard W. Clapp

Masters Theses

Introduction

The use of antibiotics has increased the average life expectancy of mankind. They have prevented and cured infectious diseases that previously terminated in death. Consequently, recovery is often prompt and complete.

Though a benefit to mankind, the use of antibiotics in the treatment of infectious disease has also been accompanied by new problems. For example, treatment of a primary infection such as a bacterial pneumonitis with a broad spectrum antibiotic, may result in the death of some of the bacteria. More than one species of bacteria, however, are often found in the infected area. If such be the situation, …

Investigation Of Possible Autotoxicity In Daucus Carota L., Carole Greer Smith

Masters Theses

Section I

Introduction

Results of recent research indicate the probable existence of plant-produced chemical substances which affect the behavior of other plants. Germination-inhibiting, and growth-inhibiting substances have been found to be widely distributed throughout the Plant Kingdom (Garb, 1960). Although the presence of inhibitors has been demonstrated in laboratory experiments, their ecological significance has not been clearly defined.

A preliminary study by the writer indicated the probability of autotoxicity in Daucus carota L., a biennial common to fields and roadsides in the northeastern United States. This study suggested the following investigation which was undertaken to determine more specifically the effects …

An Analysis Of Cytological Screening For Cervical Cancer (A 7 Year Survey), Phoebe E. Rutherford

Masters Theses

Introduction

It is the purpose of this study to review the cervical cancers, stained by Papanicolaou (1956:3-6) method, at Borgess Hospital, Kalamazoo, Michigan, from September, 1956 to September 1963.

A previous analysis of the cytological screening at Borgess Hospital to ascertain the per coat accuracy in cervical diagnoses, was made by the investigator in June, 1961. This study, covering a four year period, draw attention to the fact that the patients with invasive carcinoma were in a much older age group than any other reported series studies. This fact plus the rapid recognition, by physicians and patients, of the value …

Behavioral Interactions In A Fixed Aggregation Of Bobwhites, Jack Pierce

Masters Theses

Introduction

Many observations have been made on the behavior in the field of the bobwhite (Colinus virginianus) and of other gallinaceous birds. Stoddard (1950) has described in some detail various aspects of bobwhite behavior. Stokes (1963) conducted a laboratory study on the agonistic and sexual behavior of the chukar partridge. No behavioral studies, to the writer's knowledge, however, have been conducted on bobwhites under controlled environmental conditions. The birds used in the present study were housed in individual cages and were arranged in an artificially fixed aggregation (Fig. 1). The birds were maintained in this condition through the experimental period …

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 …
