Spectrophotometric And Microbiological Determination Of The Stability Of Sodium Ampicillin As Affected By Ph, Enrico Frank Raffanti

University of the Pacific Theses and Dissertations

The specific purpose of this investigation was to determine the effect of pH on the stability of ampicillin sodium for injection. Then, to correlate this information, a pH profile may be established to predict chemical stability with ampicillin sodium alone or when other drugs may be included in the admixture. With a pH profile the pharmacist could predict the length of time after which more than a 10 percent loss of activity would occur. Stability measurements were to be accomplished through a microbiological assay after adding ampicillin sodium to different buffer solutions. At the end of four hours, eight hours, …

The Formulation And Physical Analyses Of Antibiotic Aerosol Foams For The Development Of Potential Topical Dermatologicals, Joseph Alexander Woelfel

University of the Pacific Theses and Dissertations

Within the last two decades the consumer market has been deluged with a diversity of aerosol products. The acceptability and utility of these products is reflected by the number found in the household and industry.

An antibiotic foam would obviate the necessity of manual application as is the case with the ointment or cream type products. Therefore, there would be less irritation to the already traumatized or infected sites by mechanical, chemical, or bacterial vectors.

Thus, the objective of this research will be to systematically develop suitable aerosol foam systems which contain therapeutically effective topical antibiotics with a subsequent evaluation …

Metabolic Role Of Sulfates And Sulfides Producing Bacteria In Pollution Of Waters, M. I. H. Aleem

KWRRI Research Reports

Cytochrome transport particles from Nitrobacter catalyzed nitrite, ascorbate as well as NADH oxidation with concomitant phosphate esterification yielding P/0 ratios of 1.0, 0.6 and 2.0 respectively. Phosphorylation coupled to nitrite oxidation was not effected by rotenone, amytal or antimycin while 50 and 70% inhibition of the NADH-linked phosphorylation was observed in the presence of HOQNO and rotenone respectively. Cell-free extracts from Nitrobacter also catalyzed an energy-dependent reduction of NAD⁺ by nitrite. The reduction of cytochrome c by NŌ₂ was energy-dependent which involved the reversal of electrons from cytochrome a₁. The subsequent energy-linked reduction of the flavoproteins …

Mathematical Model Of Placental Oxygen And Carbon Dioxide Exchange, Ester P. Hill

Loma Linda University Electronic Theses, Dissertations & Projects

This model of placental CO₂ and O₂ exchange calculates the time course of changes in P_^CO2, [HCO₃^-], and [H⁺] in each of four "compartments" of placental exchange vessels: maternal erythrocytes, maternal plasma, fetal plasma and fetal erythrocytes. The changes in hemoglobin-bound CO₂ (carbamate) and oxyhemoglobin contents within the erythrocytes are also calculated, permitting consideration of the Haldane and Bohr effects. Equations were written to represent one-dimensional steady state CO₂ and O₂ diffusion between concurrent maternal and fetal capillaries and the subsequent hydration, carbamino and oxyhemoglobin reactions. The equations …

Implications Of An Oral-Gestural Training Program In The Acquisition Of Speechreading Skills, Mary Lu Wood

Dissertations and Theses

In order for the hearing handicapped child to derive maximum benefit of language acquisition through maturation, a method of receptive communication is essential at the earliest age possible. It is felt that speechreading is this method. The need for a method of training speechreading cues to prelingual, aurally handicapped children is based on the fact that most visual speechreading methods require the use of language. If speechreading can be regarded as a learning process involving the discrimination of visual cues that maybe disassociated from language expression then training the child to discriminate various facial expressions may actually enhance speech-reading ability. …

The Duration Of The Effect Of Different Carbohydrates On Neutrophilic Phagocytosis, Judy L. Reeser

Loma Linda University Electronic Theses, Dissertations & Projects

In order to determine the duration of the effect of glucose, fructose, sucrose, honey, starch, and orange juice on neutrophilic phagocytosis, 10 subjects underwent a complete series of carbohydrate tolerance tests. Blood samples were drawn at specific time periods following ingestion of 100 grams of each carbohydrate. Blood was then analyzed for glucose and phagocytic index (the mean number of bacteria engulfed per leukocyte); a red blood cell and white blood cell count and differential white cell count were done also on about 1/2 of the samples. In addition, 7 other subjects participated in a fasting study in which no …

The Effect Of Early Postpartum Teaching Of Infant Feeding On Maternal Concern, Linda M. Richter, K. Judy Toews

Loma Linda University Electronic Theses, Dissertations & Projects

An experimental study was conducted on thirty primiparae during the postpartum period to determine if individualized instruction regarding infant feeding would result in a lower level of maternal concern in this area. The study sample was randomly and evenly divided into a control and an experimental group. It was statistically determined that the two groups were homogeneous in regard to age, education, occupation, previous information (prenatal classes and reading) and help at home. The experimental group received individualized instruction by the researchers concerning their chosen method of infant feeding on the second postpartum day. There was no instruction given the …

The Effects Of A Topically Applied Anti-Inflammatory Agent On Root Resorption In The Replanted Teeth Of Canines, William L. Young

Loma Linda University Electronic Theses, Dissertations & Projects

Root resorption is a constant finding on the roots of replanted teeth. In this study it was suggested that root resorption is perhaps related to inflammation and that teeth incubated in an anti-inflammatory agent such as triamcinolone acetonide, a corticosteroid, before replantation would have less resorption. To investigate this hypothesis nineteen mature teeth in five mongrel dogs were extracted and replanted. Ten of the teeth were incubated for five minutes in the steroid and nine control teeth for the same period in a saline solution. Before euthanizing the animals at one, three, five, and seven weeks, a clinical evaluation of …

A Comparison Of Various Teaching Methods For Patients With Chronic Obstructive Pulmonary Diseases, B. Carol Altizer, Nancy S. Bailey

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to find out whether patients with chronic obstructive pulmonary disease (C.O.P.D.) learn more from auditory or from visual teaching. Of the 30 patients in the sample, 10 used a programmed instruction booklet, 10 used a taped recording of the same programmed material and 10 were in a control group which received no specific teaching.

A pre-test was given to each of the patients who met the criteria for the study. One researcher gave the pre-test through an oral interview with the patient. After the pre-test, the patient received the teaching device assigned to him …

Using A Participating Relationship To Improve Teen-Age Unwed Mother's Self-Esteem, Linda Gail Reeves

Loma Linda University Electronic Theses, Dissertations & Projects

The study was to provide an approach to help teen-age unwed mothers increase their feelings of self-esteem and thereby attain a conceptual buffer for better coping with life. Self-esteem was defined as individual perception of the worth of oneself relative to that of significant others. The hypothesis tested was that the participating relationship a community health nurse has with a teen-age unwed mother will significantly increase the mother's self-esteem as measured by statistical Q-Sort analysis.

A convenience sample of twenty teen-age unwed mothers was obtained from referrals from San Bernardino County Health, Welfare, and Probation Departments. The girls were between …

A Computerized Study Of Midpalatal Suture Expansion, Clelan G. Ehrler

Loma Linda University Electronic Theses, Dissertations & Projects

An investigation has been conducted to consider the effects of midpalatal suture expansion on the cranial-facial complex. Nine patients were treated that had constricted maxillae. Data was obtained from frontal and lateral headplate radiographs which were taken at four intervals during treatment. The Rocky Mountain Data Systems diagnosis was utilized to interpret the radiographic data.

The data from the nine cases were averaged to obtain a composit [sic] change at each of the four times.

Examination of the lateral headplate data revealed that no permanent significant alteration occurred to the positions of the mandible or maxilla in a vertical or …

Influence Of Temperature Of Incubation And Type Of Growth Medium On Pigmentation In Serratia Marcescens, Robert P. Williams, Cora L. Gott, S M. Qadri, Randolph H. Scott

Faculty, Staff and Student Publications

Maximal amounts of prodigiosin were synthesized in either minimal or complete medium after incubation of cultures at 27 C for 7 days. Biosynthesis of prodigiosin began earlier and the range of temperature for formation was greater in complete medium. No prodigiosin was formed in either medium when cultures were incubated at 38 C; however, after a shift to 27 C, pigmentation ensued, provided the period of incubation at 38 C was not longer than 36 hr for minimal medium or 48 hr for complete medium. Washed, nonpigmented cells grown in either medium at 38 C for 72 hr could synthesize …

Relationship Of Ventilation Ability And Positioning In Left-Sided Congestive Heart Failure Patients, Nancy E. Carson

Loma Linda University Electronic Theses, Dissertations & Projects

Proper positioning is used to relieve dyspnea, edema, and fatigue in congestive heart failure patients. According to the review of literature, improved ventilation as measured by specific lung volumes and lung mechanics occurred with upright positioning in normal persons. The effects of specific changes in lung volumes related to position change in congestive heart failure patients has not been documented in literature, although various recommendations related to positioning are made. This exploratory study was undertaken with nine congestive heart failure patients to see if a relationship existed between degree of head elevation and lung ventilation ability as measured by water-bell …

A Note On The Probability Of Misclassifying Students On The Basis Of A Multiple Choice Examination, Walter H. Carter Jr.

MCV/Q, Medical College of Virginia Quarterly

The students' ability to guess correctly questions on a multiple choice examination creates a problem in the determination of the number of questions the students actually knew. Therefore, it is not unlikely that mistakes will be made when grades are assigned. In this paper, a method for calculating the probability of misclassification of students as a result of a multiple choice test in which the assumption of a uniform guessing distribution is relaxed has been discussed and illustrated. To do this it is necessary to include on the examination several questions, related to the subject matter on which the students …

The Use Of Principal Component Analysis To Increase The Ability Of Multiple Choice Examinations To Distinguish Among Students, Flora E. Roger, Walter H. Carter Jr.

MCV/Q, Medical College of Virginia Quarterly

A method of scoring multiple choice examinations based on the statistical technique of principal components analysis is described. This test is applied to two tests. The results indicate that the method yields test scores which have a marked advantage over the usual percentage scores in distinguishing among examinees with respect to knowledge of subject matter. In addition, the method provides an indication of whether a question is "good" or "poor" for purposes of distinguishing among examinees.

Procedures For Trace Analysis Of Dissolved Inorganic And Organic Constituents In Water, Gary D. Christian, Charles E. Matkovich, W. Lynn Schertz

KWRRI Research Reports

A study of different solvent systems for the atomic absorption determination of cobalt revealed that acetone results in best sensitivity. Acetone is the solvent of choice for the sensitive measurement of several metals. Hence, methods were investigated for the separation of acetone from water by salting out so that possible solvent extraction of metal chelates into this solvent could be performed. About two-thirds saturated calcium chloride proved to be the best system for salting out of the acetone. It is essentially a neutral salt and is in general a weakly complexing salt, resulting in minimum interference in solvent extractions. Solvent …
