Treflan And The Oxygen Consumption Of Green Sunfish (Lepomis Cyanellus), Barbara Jo Warner Jan 1975

Treflan And The Oxygen Consumption Of Green Sunfish (Lepomis Cyanellus), Barbara Jo Warner

Masters Theses

Oxygen consumption rates of 51 green sunfish (Lepomis cyanellus, Rafinesque) were monitored over five hours exposure to Treflan E.C. concentrations of 0, 0.32, 0.56, 1.0, and 2.0 ppm. There was a great variation in the responses of the fish at each concentration; and Student's t-tests revealed no significant differences. However, graphs of the mean hourly oxygen consumption rates showed certain trends. During the fifth hour of exposure, there appears to be an acclimation to the Treflan at concentrations of 0.32 and 0.56 ppm; but no such acclimation at the higher concentrations of 1.0 and 2.0 ppm. Hourly oxygen …


Parasites Of Channel Catfish In Illinois Hatcheries, Charles Dale Meryman Jan 1975

Parasites Of Channel Catfish In Illinois Hatcheries, Charles Dale Meryman

Masters Theses

Ninety channel catfish (Ictalurus punctatus) were trapped during September 1973 through April 1974 at three hatcheries located at Worden, Centralia, and Kinmundy, Illinois. All were examined for parasites and 87 were parasitized. The trematodes Azygia angusticauda and Neascus sp. were found in the gastrointestinal system and Cleidodiscus floridanus and Dactylogyrus sp. were attached to the gills. Five cestode genera, including Bothriocephalus sp., Corallobothrium giganteum, Eubothrium sp., Haplobothrium sp., and Proteocephalus ambloplitis were present. Rhabdochona sp. was the only nematode found. Protozoans; Costia sp., Myxobolus sp., Scyphidia macropodia and Trichodina discoidea and one kind of glochidium were observed. …


Pesticide Residues In The Illinois Wild Turkey, John M. Bridges Jan 1975

Pesticide Residues In The Illinois Wild Turkey, John M. Bridges

Masters Theses

Adipose tissue from 55 turkeys, killed during the 1974 hunting season in southern Illinois, was grouped by age and location of the birds, and the pesticide concentrations in them were determined by gas/liquid chromatography. Twelve different pesticides were identified in the samples with only four, total DDT, heptachlor epoxide, toxaphene, and linuron, being present in all samples. Concentrations ranged from 0.02 ppm to 0.88 ppm.

Studies In Slipped Capital Femoral Epiphysis, Theodore Simon Jan 1975

Studies In Slipped Capital Femoral Epiphysis, Theodore Simon

Yale Medicine Thesis Digital Library

[From the Introduction] This study serves to define the population at risk for developing slipped capital femoral epiphysis (SCFE). Although epidemiological studies of this disease have been completed, this large sample helps to confirm the earlier work. Moreover, it characterizes the relationship of this sample with previous samples and hence evaluates the contention that the results of other studies on this sample are based on a typical group of SCFE victims.

A Compatibility Profile Of Selected Therapeutic Agents In Balanced Electrolyte Solutions, Harry Michael Tozlian Jan 1975

A Compatibility Profile Of Selected Therapeutic Agents In Balanced Electrolyte Solutions, Harry Michael Tozlian

University of the Pacific Theses and Dissertations

Through the years, various studies (1-5) have been done regarding the prevalent practice of adding one or more drugs to parenteral fluids. The greater variety of drugs being used intravenously, plus the formulation of newer and more complex parenteral fluids, has led to an increased awareness of potential incompatibilities existing between drug and solution. Recognition of the hazards of such extemporaneous combinations has necessitated the study of drug stability in solution.

The objective of this report is to determine compatibility characteristics of admixtures prepared from a series of balance intravenous electrolyte solutions and a group of commonly used therapeutic agents. …

Studies On The Characterization And Activiation By Soluble Factor Of A Sodium-Activated, Magnesium-Dependent, Adenosinetriphosphatase In Rat Cerebral Cortex, Alan B. Forrest

University of the Pacific Theses and Dissertations

This study presented evidence for the existence of a membrane-bound, sodium-activated ATPase which does not require potassium ions for its activity. Furthermore, the data suggest the presence of a soluble factor which activates this enzyme and may play a regulatory role in sodium transport.


Application Of Clinical Pharmacy In The Rural Community : The Livingston Project, Gregory Paul Matzen Jan 1975

Application Of Clinical Pharmacy In The Rural Community : The Livingston Project, Gregory Paul Matzen

University of the Pacific Theses and Dissertations

During the past few year's the health care delivery system of the United States has come under increasingly close scrutiny and attack by citizens concerned over the illogical distribution and cost of receiving adequate health care. Outcries for changing our current standards of health care delivery have reached the attention not only of consumer groups but also influential individuals in various levels of state and federal government. One need only look at proposed legislation (1-3) recently introduced in both the United States Senate and the House of Representatives , concerning enactment of some form of national health insurance, to grasp …


The Social History Questionnaire As A Predictor Of Therapeutic Outcome, Susan E. Suter Jan 1975

The Social History Questionnaire As A Predictor Of Therapeutic Outcome, Susan E. Suter

Masters Theses

One of the most critical problems encountered in clinical practice concerns the outcome criteria used for predicting therapeutic improvement. At present, there is no single outcome criteria that is universally accepted as evidence of improvement. Representative studies by Lubarsky et al (1971) have emphasized the magnitude of this problem by citing the many patient variables that may effect the outcome of a therapeutic relationship.

The importance of this therapeutic relationship in terms of time and committment on the part of both the therapist and the client, necessitates some objective means for first, the development of an instrument that can measure …


A Photomicrographic Guide To The Saprolegniaceae Of Illinois, Ronald L. Butler Jan 1975

A Photomicrographic Guide To The Saprolegniaceae Of Illinois, Ronald L. Butler

Masters Theses

There is a paucity of information concerning the occurrence and distribution of the Saprolegniaceae of Illinois. These fungi, commonly called "water molds", are of particular interest as many are potential parasites of fish, crustaceans, and other aquatic plant and animal life. It is of considerable interest to students of the fungi and of practical value to the fisheries biologists and environmentalists to have available a means of identification for these organisms.

This paper provides a descriptive and photomicrographic account of the Saprolegniaceae of Illinois. Included herein are dichotomous keys to the genera of this family as well as generic descriptions …


An Investigation Of The Behavioral Effects Of Methylphenidate Hydrochloride On Schedule-Induced Polydipsia In Rats, Linda Sederquist Smith Jan 1975

An Investigation Of The Behavioral Effects Of Methylphenidate Hydrochloride On Schedule-Induced Polydipsia In Rats, Linda Sederquist Smith

Masters Theses

The influence of methylphenidate hydrochloride injections on six male Charles River rats displaying schedule induced polydipsia was examined in this study. Bar pressing, licking, and water consumption were measured during a total of 63 daily one hour trials conducted with a variable interval 60-second schedule of bar pressing for pellets with water constantly available. The polydipsic response was acquired by subjects during the first 28 trials. Subjects were then divided into experimental and control groups. The experimental subjects recieved a 1 mg/kg injection of methylphenidate prior to regular trials 29-49 and extinction trials 50-63. Control subjects were injected with a …


An Exploration Of The Relationship Between Loneliness And Differential Diagnosis In A Rural Mental Health Center, Kathryn Dunscomb Jan 1975

An Exploration Of The Relationship Between Loneliness And Differential Diagnosis In A Rural Mental Health Center, Kathryn Dunscomb

Masters Theses

The review of the literature discussed loneliness in general and specified three seperate forms of loneliness; social, psychic, and existential. The relationships between loneliness, social interaction, and pathology were discussed. 139 clients were given the Belcher Extended Loneliness Scale - Revised prior to therapy. They were assigned one of six diagnostic categories to determine loneliness score (LS), diagnostic, and sex interactions. An analysis of variance found a significant difference (p <.0001) between the diagnostic categories’ LS. The schizophrenic’s and the neurotic’s LS s were significantly higher (<.05) than the remaining categories. The males had significantly (p <.036) higher LS than the females. It was also hypothesized that the degree of loneliness would increase the lower the diagnostic developmental level. The hypothesized order was not consistent with the results. Further research was recommended.


The Development Of A Course Of Study In Fda Drug Regulatory Procedures, Robin Adele Wills Jan 1975

The Development Of A Course Of Study In Fda Drug Regulatory Procedures, Robin Adele Wills

University of the Pacific Theses and Dissertations

It is the purpose of this thesis to develop a course of study for pharmacy schools on drug regulation by the Food and Drug Administration (FDA). A summarization of the history of the development of the Food and Drug Administration (FDA) and of pharmacy education reveals a lack of interface between the two. The necessity for the interface of pharmacy education and the agency which has significant control over the products forming the basis of the pharmacy profession will be made apparent. A period of residency through which the course of study on drug regulation by the FDA was to …


Studies On The Characterization Of A Soluble Factor Of A Sodium-Activated, Magnesium-Dependent Adenosinetriphosphatase In Rat Cerebral Cortex, Lily Toh Jan 1975

Studies On The Characterization Of A Soluble Factor Of A Sodium-Activated, Magnesium-Dependent Adenosinetriphosphatase In Rat Cerebral Cortex, Lily Toh

University of the Pacific Theses and Dissertations

From the standpoint of physiologists, emphasis has been placed on viewing the chemical nature of the membrane as an operational barrier to the free diffusion of ions. This tends to explain the fact that the ionic composition of the cytoplasm of the animal cell differs from its external fluid environment.

It is well know that where sodium is the principal cation of the extracellular fluid, potassium has such a role inside the cell. Since there appears to be differential distribution of these ions across the cell membrane, this infers a concentration gradient of these ions. This differential distribution is important …

Stability, Packaging, Storage, And Sterilization Of A Medicated Dry Foam, Armen Gostanian Jan 1975

Stability, Packaging, Storage, And Sterilization Of A Medicated Dry Foam, Armen Gostanian

University of the Pacific Theses and Dissertations

The basic unmedicated formula consists of dextran, sorbitol, Miranol 2 MCA Modified, and water. The major advantages of the film are 1) fast release rates, 2) ease of application to denuded skin without aggravation, and 3) lack of necessity for removal, hence no aggravation. However, it is extremely sensitive to moisture and elevated temperatures which is a major disadvantage. Excessive humidity will solubilize the film or make it too tacky to handle while very low humidity causes the film to lose its flexibility. Also, elevated temperatures remove moisture from the film and cause it to lose flexibility much as with …


An Evaluation Of Centrifuged Vs Electronically Determined Hematocrits In Assessing The Degree Of Polycythemia In Cyanotic Congenital Heart Disease, Marsha Rene Jones Jan 1975

An Evaluation Of Centrifuged Vs Electronically Determined Hematocrits In Assessing The Degree Of Polycythemia In Cyanotic Congenital Heart Disease, Marsha Rene Jones

Theses and Dissertations

Secondary polycythemia is defined as an absolute erythrocytosis caused by an enhanced stimulation of red blood cell production. One of the most common methods of monitoring the degree of polycythemia is the measurement of the hematocrit. The hematocrit is the measurement of the volume of red blood cells.expressed as a percentage of the volume of whole blood in a sample. This measurement is usually done using one of two methods: (1) the Coulter Model S® or (2) the centrifuged micro-hematocrit method. However, we have noted a significant difference in the hematocrit values determined by these two methods when the hematocrits …


Metastatic Patterns And Functional Disability In Disseminated Breast Carcinoma, Stephen Adam Gudas Jan 1975

Metastatic Patterns And Functional Disability In Disseminated Breast Carcinoma, Stephen Adam Gudas

Theses and Dissertations

Thirty female outpatients with metastatic breast carcinoma were evaluated using two operational models constructed for the purpose of assessing and assigning a quantitative score for (A) extent of metastatic disease and (B) level of functional disability. These patients were drawn from the population of patients with disseminated breast carcinoma attending the medical oncology clinics at the Medical College of Virginia Tumor Clinics for a 49 day period in 1975. The data from this patient sample were used to test several hypotheses.

Each patient underwent an initial screening procedure designed to clearly identify those patients with disseminated disease. This was followed …
