Intracellular Ph Determination By Means Of Ph Glass Microelectrodes, Norman W. Carter

MCV/Q, Medical College of Virginia Quarterly

A number of years ago I decided to attempt to measure the intracellular pH of skeletal muscle by a more direct method than those in current use, that is, by an electrode. I excluded all forms of pH electrodes except the glass electrode and then set up a certain number of characteristics or requirements that this electrode should have. First, the electrode should be insulated in such a manner that only the pH-sensitive portion is in the cell cytoplasm. Second, the reference side of the electrode group should also be within the cell, because the cell has a transmembrane potential; …

Diagnostic Ultrasonography, Joseph H. Holmes

MCV/Q, Medical College of Virginia Quarterly

It was the development of radar and sonar during the last World War which made the ultrasonic techniques I am going to talk about possible. Following the War, Dr. K. T. Dussik had the idea that, if one directed ultrasonic waves into the body, one might obtain echoes reflected from tissue surfaces in the same way that the Navy received echo information reflected from the submarine's hull. When he did this, he did get reflected echoes from within the body, and this opened the door for other investigators to demonstrate how this echo information could be made useful in diagnostic …

Studies On The Metabolism And Excretion Of Chlorine Chloride, John Thomas Mccloskey

University of the Pacific Theses and Dissertations

The organic base choline is of considerable interest to the physiologist because of its role in normal metabolic function, and to the pharmacologist because of its possible application in the treatment of several human diseases.

The overall function of choline in the biologic system must be seen as an equilibrium between its lipotropic activity as a whole molecule and its function as a source of methyl groups in biochemical reactions.

IV. Investigation Undertaken in This Study

Due to the long-standing and as yet unresolved question dealing with the relative merits of the path by which choline leaves the intestine, these …

Localization of Mycoplasma pulmonis in the lungs of infected gnotobiotic mice by electron microscopy. J. Bacteriol. 92:1164–1176. 1966.—Lesions in lungs of gnotobiotic mice inoculated intranasally with Mycoplasma pulmonis were examined by electron microscopy after osmic acid fixation. At 1 week after infection, mycoplasma cells were found in large numbers in the bronchi at the surface of bronchial epithelial cells and, in smaller numbers, in the alveoli where active phagocytosis by polymorphonuclear leukocytes (PMN) occurred. …

Biochemical Properties Of Salmonella Potsdam Bacteriophage P4/2, Clyde L. Roggenkamp

Loma Linda University Electronic Theses, Dissertations & Projects

Over 90% recovery of phage P4/2 was realized with differential centrifugation concentration and purification, whereas only about 16% was recovered from the aqueous two-phase polymer - Genetron - ECTEOLA-cellulose column system. Purity of preparations was greatest with the density gradient centrifugation (A₂₆₀ = 2.66 and A₂₈₀ = 1.80 per 10¹² plaque-forming units). With the chemical system of concentration and purification followed by an ECTEOLA anion exchange run, the A₂₆₀ was 6.6 and the A₂₈₀ was 4.3.

Three tests were employed to determine the configuration of P4/2 DNA: (1) a formalin denaturation test, (2) a thermal …

The Fecal Shedding Of Listeria Monocytogenes By Conventional And "Germ Free" Mice, Margaret Joyce Ramsay

Loma Linda University Electronic Theses, Dissertations & Projects

A series of experiments involving Listeria monocytogenes was undertaken to study first the fecal shedding of Listeria by conventional mice challenged intraperitoneally with Listeria and second the fecal shedding and ability to survive of germ free mice with similar challenge. In addition, mites infesting Listeria infected mice were cultured for their possible contamination by Listeria.

Conventional mice were challenged intraperitoneally with a single near LD₅₀ dose of Listeria. Fecal Listeria were detected by collecting specimens from each mouse daily for the first 4 days and every second day thereafter. The feces was held at 7°C for 14 …

Individual scores were computed and comparative analyses done on scores of groups of students representing the two different educational levels, sex differences, two …

Principles Understood By Nurses Relative To The Care Of Tracheostomy Patients, Mary Ann Featherstone

Loma Linda University Electronic Theses, Dissertations & Projects

A descriptive study was conducted to determine what scientific principles were understood by nurses relative to the care of tracheostomy patients. A random sample of thirty-five nurses: twenty-four from medical-surgical units, three from pediatric units, and eight nurses from intensive care units, were selected from nurses working at two community hospitals. The interview method was used to obtain the data. An interview guide was developed from information gained in the literature review and findings of the pilot study.

The findings of the study indicated that the nurses realized speech would be lost with tracheostomy, but other essential physiological changes were …

An Organ Culture Technique For Maintaining The Pulp Tissue Of Intact Human Teeth, John P. Devincenzo

Loma Linda University Electronic Theses, Dissertations & Projects

The size of explants in organ culture is limited by their ability to feed, respire, and excrete by diffusion. The perfusion procedure described in this report is not limited to a particular explant size. The test tissue was the adult human tooth.

In order to maintain the pulp tissue of the intact human tooth in organ culture, special precautions were taken to prevent internal necrosis and to allow diffusion of nutrients and waste products. Using aseptic technique, a standard tissue culture medium plus appropriate antibiotics were delivered to a glass manifold housed in an incubator with an atmosphere at 100% …

Two Methods Of Collecting Clean-Voided Urine Specimens, Jo Helen Butner

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to find out if there was a need to cleanse the genitalia in women before obtaining a clean-voided urine specimen.

The experimental method was chosen as the method of study. Two clean-voided urine specimens were obtained from twenty-six nursing students in a selected school of nursing. One clean-voided urine specimen was obtained from each subject where the genitalia had not been cleansed and compared with a second clean-voided urine specimen obtained the following day from the same subject where the genitalia had been cleansed.

It was found that there was a mean of 54,438 …

Application Of The Ninhydrin And Alloxan Reactions To Tissue Sections, Nabil A. Azzam, William M. Shanklin

MCV/Q, Medical College of Virginia Quarterly

The ninhydrin and alloxan reactions have been criticized as being nonspecific and unreliable for histochemical studies due to the diffusion, solubility, and fading of their reaction products. This paper presents some modifications of the techniques that appear to render the reactions more reliable for the identification of proteins and peptides possessing terminal α-amino acids. The resulting color complexes are also stable.

A Tissue Culture Perfusion Chamber With A Substratum Of Reconstituted Collagen, Thomas M. Harris

MCV/Q, Medical College of Virginia Quarterly

A tissue culture chamber is described that introduces the concept of a fixed platform within a "perfusion type" chamber. The platform is made of stainless steel mesh covered with a membrane of reconstituted collagen. The collagen membrane serves as the supporting substratum for the cultured tissue and is of such an optical quality as to permit phase-contrast microscopic observation of the tissue. The perfusion chamber is a Sykes-Moore tissue culture chamber modified to twice its normal depth to receive the screen. Cell growth in the experimental chamber is superior to growth in the control chamber both in speed of proliferation …

On The Nature Of The Resting Frog Skin Potential, Priscilla M. Winn, Nancy S. Laprade, William R. Tolbert, Ernst G. Huf

MCV/Q, Medical College of Virginia Quarterly

In this paper some of the highlights of research on the nature of the resting frog skin potential have been presented. Reviewing a period of about 30 years, it was the intention to show that several key problems have been recognized by a number of investigators who, through their experimental work, have tried to find unequivocal solutions to such problems as follows: a) The number and location of electrogenic layers (barriers) within the rather complex epidermis. b) The characterization of these barriers in terms of specific permeability properties. c) The electrical response of the two sides of the skin to …
