Mitochondrial Activity Of Hardened And Nonhardened Rye (Secale Cereale) Plants Exposed To Freezing Temperatures, Bryce D. Bennett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Five day old dark-grown seedlings of Secale cereale variety "cougar" grown at 20 C were subjected to hardening at 2 C in daily increments from 0 to 7 days, to temperature stress at -5 C for 0, 1, and 3 days, and to recovery at 20 C for 0, 1, and 3 days. Unhardened plants were killed by temperature stress but as the time of hardening increased fewer plants were killed. After 5 days of hardening all plants survived subsequent freezing stress.

Mitochondria were isolated from the plants after they received various combinations of the three temperature treatments. There were …

Proteolytic Enzymes Of Lactic Streptococci And Their Use In Improving Body And Texture Of Direct Acid Cottage Cheese, Gulamnabi Y. Vahora

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Proteolytic activity of Streptococcus cremoris HP, P₂ and AM₂; Streptococcus lactis-C₂, ML₈ and a commercial mixed culture was determined in skimmilk and whey by measuring the increase in Absorbency at 274.5 nm of a pH 4.6 soluble filtrate, following incubation in a 2.5% casein solution. Proteolytic activity, rate of acid production and growth rate decreased in order of C₂, HP, mixed culture, AM₂, ML₈ and P₂ at a regulated pH (6.1 - 6.2) and 32 C. Maximum proteolytic activity for all cultures was found during the stationary …

U.S.U And The New Toxicology, Joseph C. Street

Faculty Honor Lectures

Toxicology, a branch of science once concerned only with poisons for their medical effects and legal con sequences, has undergone in recent years a metamorphosis on a major scale. The general field of toxicology is defined as the qualitative and quantitative study of the injurious effects of chemical agents, as detected by alterations of structure and function in living systems (Murphy and Hayes, 1972). In common with most other disciplines it has benefited from a growing sophistication in research methods and has particularly flourished in the wake of major advances in physiology, biochemistry and the other basic sciences that serve …

Lymphocyte-Induced Polymorphonuclear Leukocyte Stimulation, Christine Kull (Walsh)

Yale Medicine Thesis Digital Library

[From the Summary] Reactions of cellular hypersensitivity often involve the participation of different cell types. The communication between lymphocytes and polymorphonuclear leukocytes was investigated. Human sensitized lymphocytes exposed to old tuberculin were found to have a stimulatory effect of polymorphonuclear leukocytes as indicated by the latter's increased glucose-1-14c oxidation and lysozyme production. Similar results were obtained using lymphocytes non-specifically stimulated by phytohemagglutinin. Activation of lymphocytes required a latent period (24 hour) followed by rapid stimulation of polymorphonuclear leukocytes (2 ours). These results suggest that increased glucose-1-14c oxidation and lysozyme production may be related to enhanced microbicidal activity. A possible mechanism …

The Doctor-Patient Relationship Revisited. An Analysis Of The Placebo Effect., Herbert M. Adler, Md, Van B. Hammett. Md

Department of Psychiatry and Human Behavior Faculty Papers

An overview of prescientific medicine, evolution, and individual human development is presented in an attempt to discover the generic factors operating in all interpersonal therapies. We hypothesize that the placebo effect rests on the universal human need for a group and, by symbolic extension, a system.

The Effect Of Psyllium Hydrocolloid And Cholestyramine On Hepatic Bile Lipid Composition In Man, W. T. Beher, B. M. Schuman, M. A. Block, G. J. Lin, K. K. Casazza

Henry Ford Hospital Medical Journal

The effects of a mucoid - psyllium hydrocolloid - and an anion exchange polymercholestryamine - on the total cholesterol, total phospholipid, total bile salt, cholate, chenodeoxycholate, and deoxycholate concentrations of hepatic bile were determined in six post-cholecystectomy patients. Bile was obtained by drainage through an indwelling T-tube, which was clamped except during bile collection. Psyllium hydrocolloid treatment (12 gm/day) for 6 to 29 days had little or no effect on the cholesterol or phospholipid concentration of hepatic bile, but increased the total bile salt pool by gradually increasing the concentration of deoxycholate. Cholestyramine treatment (12 gm/day) for 8 to 12 …

Kinesiology Of Knee Flexion Deformity Using Electromyography, Paul J. Roby

Loma Linda University Electronic Theses, Dissertations & Projects

A kinesiological electromyographic study was completed to determine the relative changes in muscle activity as a person walks and stands with different degrees of knee flexion deformity. The ultimate aim was to establish criteria for appropriate preventive and corrective measures relating to knee flexion deformity.

Six different muscles were implanted with wire electrodes. The subjects performed a series of walking and standing experiments with the knee flexed at selected angles by a locking leg brace to simulate knee flexion deformity. The electromyographic action potentials were monitored by analog tapes, oscilloscopes and closed circuit television. The analog tapes were displayed on …

Pneumotachograph, Louis Diamond, William T. Lipscomb

Pharmacology and Nutritional Sciences Faculty Patents

A pneumotachograph suitable for measuring flow rates of respiratory gases in small animals and comprising essentially a flow-resisting element which can be placed in series with a subject''s airway. The pressure drop across the resistive element is proportional to the rate of airflow and is linear over the range of flows which one normally would expect to encounter in small animals (0-2 liters/min.).

Advancing Technology Of Clinical Laboratory Practice, George Z. Williams

MCV/Q, Medical College of Virginia Quarterly

In spite of the temporary antitechnology attitude of a portion of our society, the future will be an era of automated technology. Buckminster Fuller has reviewed the progress of industrial technology and points out that continuing scientific advances are inevitable and that technical applications will provide more equitable distribution of wealth, more time, more opportunity for education and intellectual pursuits.

The Modernization Of The Autopsy: Application Of Ultrastructural And Biochemical Methods To Human Disease, Benjamin F. Trump, Jon M. Valigorsky, Jane H. Dees, Wolfgang J. Mergner, Kook M. Kim, Raymond T. Jones, Robert E. Pendergrass, Joel Garbus, Julio H. Garcia, Jesus E. Viloria, Junichi Tanaka, Hannu Kalimo, Yoshinari Kamijyo, R. Adams Cowley

MCV/Q, Medical College of Virginia Quarterly

The autopsy has provided, and still provides, the stimulus for many attempts to reproduce disease in experimental animal models. This approach has become increasingly difficult, however, in the case of human disease, principally shock. The study of some pathological states in animal models requires testing in several species and final confirmation in man before this knowledge can be applied to living patients. In our studies the application of cell biology techniques at autopsy has permitted the generation of new hypotheses which are more amenable to further exploration in experimental models and can be more precisely related to human disease.

Some Effects Of The Bite Of The Short-Tailed Shrew, Blarina Brevicauda, Howard F. Krosch

Journal of the Minnesota Academy of Science

Folklore, especially in Europe, has long maintained that shrews are extremely poisonous. Zoologists have discounted this belief as superstition until recently, when it was learned that at least two species of shrews - the European water shrew, Neomys fodiens, and the American short-tailed shrew, Blarina brevicauda - produce a toxin in their sub-maxillary glands.

Microbial Monitoring, Harry P. Dalton

MCV/Q, Medical College of Virginia Quarterly

The need for monitoring both areas for alteration in microbial flora, which may result in invasion or adverse effect on internal organs of the host, has been an accepted scientific fact of modern medicine for years. Questions remain, however, on how much monitoring needs to be done. What areas of the patients and the environment should be tested, and what are the practical uses of the results of such monitoring? Before attempting to answer these questions, let me give you an overview of how microbial monitoring has been used at the Medical College of Virginia hospitals and other institutions to …

The Pharmacology And Clinical Use Of Lidocaine And Procainamide, J. Thomas Bigger Jr., Elsa-Grace V. Giardina

MCV/Q, Medical College of Virginia Quarterly

Both procainamide and lidocaine are useful for acutely treating cardiac arrhythmias, and procainamide can be useful in chronic antiarrhythmic regimens. Successful management of cardiac arrhythmias requires knowledge of: 1) the mechanism and natural history of the arrhythmia, 2) the physiologic state of the patient, and 3) the cardiac effects, pharmacodynamics, and general pharmacology of the antiarrhythmic drugs.

Conducting Pathways Of The Human Heart, Fergus O'M. Shiel, Fabio Gutierrez

MCV/Q, Medical College of Virginia Quarterly

For over a century the cardiac beat has been experimentally observed and analyzed. To a surprising degree the relevancy of the early researches persists, and the views of the 19th century investigators though modified, have not been eclipsed by time. It may, therefore, be appropriate to preface this clinicopharmacological seminar on arrhythmias by a brief review of the cardiac conducting pathways whose existence is generally accepted today and to retrace the concepts which led to their discovery.

Pharmacology Of Antiarrhythmics: Quinidine, Beta-Blockers, Diphenylhydantoin, Bretylium, Albert J. Wasserman, Jack D. Proctor

MCV/Q, Medical College of Virginia Quarterly

The electrophysiologic effects of the antiarrhythmic drugs, presented elsewhere in this symposium, form only one of the bases for the selection of a therapeutic agent in any given clinical situation. The final choice depends on the following factors: 1. The specific arrhythmia; 2. Underlying heart disease, if any; 3. The degree of compromise of the circulation, if any; 4. The etiology of the arrhythmia; 5. The efficacy of the drug for that arrhythmia; 6. The toxicity of the drug, especially in the given patient with possible alterations in volume of distribution, biotransformation, and excretion; 7. The electrophysiologic effects of the …

The Pathophysiology Of Respiratory Failure In Chronic Obstructive Pulmonary Disease, John L. Patterson, James P. Baker, Walter J. O'Donohue Jr.

MCV/Q, Medical College of Virginia Quarterly

The most important pathophysiologic aspects of chronic and acute obstructive pulmonary disease involve disturbances in ventilation with resulting derangement of gas exchange in the lung. There is considerable variability in the type of abnormality, the time of its appearance in relationship to the history of the disease, and in the progression of the abnormality in blood gases.

Mechanisms Of A-V Block, Leonard S. Dreifus, Joseph Mcmenamin, Demetris Kimbiris

MCV/Q, Medical College of Virginia Quarterly

Determination of the varieties of A-V block is predicated on the precise identification of the site(s) of conduction delay as prognosis, and therapy must follow on this basis. Further electrophysiologic and pharmacologic studies will undoubtedly reveal other mechanisms on the nature of A-V transmission.

The Evolution Of Sinoatrial Node Function In Man, J. Thomas Bigger, Harold C. Strauss

MCV/Q, Medical College of Virginia Quarterly

The function of the sinoatrial node is complex. In nearly all hearts, this small bit of tissue is responsible for spontaneously generating the impulse which will be distributed to the remainder of the heart, maintaining coordinated electrical and mechanical function. In recent years, it has become clear that S-A node dysfunction is not rare, can cause disabling symptoms, and often presents difficult management problems. The challenges presented by the "Sick Sinus Syndromes" have increased our desire to know more about normal S-A node function and about function in disease states.
