Amikacin: Clinical And Laboratory Studies, Erwin J. Haas, T. Madhavan, Evelyn J. Fisher, Frank Cox, Keith Burch, Edward L. Quinn, Richard D. Nichols Jun 1975

Amikacin: Clinical And Laboratory Studies, Erwin J. Haas, T. Madhavan, Evelyn J. Fisher, Frank Cox, Keith Burch, Edward L. Quinn, Richard D. Nichols

Henry Ford Hospital Medical Journal

Amikacin was evaluated in vitro against S aureus and a variety of gram negative bacilli. In concentrations of 12.5 μg/ml or less, it suppressed the growth of all organisms except 15% of Proteus mirabilis. Peak serum levels in patients, following a 7.5 mg/kg IM dose, averaged 21 μg/ml at one hour. Most of the drug appeared in the urine during the first six hours after administration. Of six patients receiving an adequate course of treatment, all but one were cured. Treatment in that patient also failed with a subsequent course of gentamicin and carbenicillin and he was cured only by …


The Effect Of Insulin, Fluoride And Methyl Xanthines On The Hypothalamic-Parotid Gland Endocrine Axis, Reagan Ondler Jun 1975

The Effect Of Insulin, Fluoride And Methyl Xanthines On The Hypothalamic-Parotid Gland Endocrine Axis, Reagan Ondler

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to determine the effect of insulin and fluoride on dentinal fluid movement (FM) in high-sucrose fed rats as mediated through the hypothalamic-parotid gland endocrine axis. In conjunction with the fluoride study, the possible involvement of cAMP was examined through the use of several methyl xanthines which are recognized as phosphodiesterase inhibitors.

Twenty-one day old, male Sprague Dawley rats were maintained on a high-sugar diet (62% sucrose) for 8-9 days at which time intravenous or arterial infusions of insulin, fluoride or the methyl xanthines were performed. Additional procedures included collecting plasma from rats which had …


The Relationship Of Alcohol Consumption In Rats To Morphine And Codeine Intake And The Metabolism Of Dopamine, Hsiu Fen Liu Dec 1974

The Relationship Of Alcohol Consumption In Rats To Morphine And Codeine Intake And The Metabolism Of Dopamine, Hsiu Fen Liu

Loma Linda University Electronic Theses, Dissertations & Projects

The effects of morphine and codeine free-choice alcohol consumption in male Sprague-Dawley rats were studied. Intakes of a 10% alcohol solution in milliliters per 100 gm. of body weight were on recorded weekly. No difference was found in the alcohol intake of rats given either a morphine-supplemented diet (0.01% of the diet) or daily injection of morphine sulfate (2 mg./kg.); however, there was a significant lower intake of water (p < .05) in those rats fed the diet with morphine. Total fluid consumption of both groups given the morphine-supplemented diet and daily injection of morphine sulfate was decreased (p < .05). It was found that morphine did not affect the percentage of total fluid consumed as alcohol or the weight gain.

Two levels of codeine phosphate (10 mg./kg. and 20 mg./kg.) were injected subcutaneously into rats twice a day. It was observed that the codeine significantly decreased alcohol intake in rats …


The Effect Of Various Doses Of Caffeine Upon The Maximal Muscular Endurance Of College Females, Roberta Jane Perkins Jul 1974

The Effect Of Various Doses Of Caffeine Upon The Maximal Muscular Endurance Of College Females, Roberta Jane Perkins

Human Movement Studies & Special Education Theses & Dissertations

A limited number of investigations dealing with the effects of caffeine upon human physical performance have been conducted. Since caffeine is a central nervous system stimulant and it is a constituent of the popularly-consumed beverages - coffee, tea, and cola drinks, it would appear that numerous studies would have been conducted in order to determine the effect of caffeine upon human muscular performance. At any rate, there is a dearth of studies on this topic and the findings of the conducted experiments are equivocal and ambiguous.

The purpose of the present study was to determine the effects of various doses …


Development Of A Selective Bait For Rabbits, A J. Oliver, S. H. Wheeler Jan 1974

Development Of A Selective Bait For Rabbits, A J. Oliver, S. H. Wheeler

Journal of the Department of Agriculture, Western Australia, Series 4

It has long been recognised that a means of killing rabbits selectively in the presence of stock would be a major advance in rabbit control. It would enable a whole farm to be treated for rabbit control at one time, saving operational costs and cutting down reinfestation of rabbits into treated areas from untreated areas.

A literature search and some pilot trials indicated that indandione derivatives were more toxic to rabbits than to ruminants.

Pindone (2- pivalyl-l,3-indandione) was selected for evaluation.


A Comparative Consideration Of Lipoprotein Distribution And Stress Response In The Mallard Duck And Man, Janice Mackay Apr 1972

A Comparative Consideration Of Lipoprotein Distribution And Stress Response In The Mallard Duck And Man, Janice Mackay

Honors Theses

Lipid is associated with all of the major serum protein fractions of both the mallard duck and man. however, whereas the ρ lipoproteins predominate in man with little lipo-albumin evident, according to available literature, in ducks the lipo-albumin constitutes more than half of the serum lipoproteins, and a substantial lipo-prealbumin fraction is evident. Most studies of lipo-proteins are carried out on human serum primarily for the purpose of diagnosis of abnormalities. The stress response in many animals includes a rise in serum α-globulin levels, but its physiological basis is still speculative. While a consideration of the changes in lipoprotein distribution …

The Duration Of The Effect Of Different Carbohydrates On Neutrophilic Phagocytosis, Judy L. Reeser Jul 1971

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 Response Of Gingival Tissues To Alterations In Ph, Robert C. Jann May 1971

The Response Of Gingival Tissues To Alterations In Ph, Robert C. Jann

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to evaluate the histopathological and clinical changes that occurred when a continuous supply of exogenous acid or base, at varying pH, was delivered adjacent to the gingival crest of the monkey. A related goal was to develop a monkey model system which would deliver test solutions continuously and atraumatically, to the experimental gingival sites.

Two young adult female monkeys had a perfusion apparatus attached to certain maxillary teeth so that test solutions were deposited atraumatically to the marginal gingival tissues. During the experimental periods the animals were kept in primate restraining chairs and fed …


Promethazine-Chlorpromazine Combination In The Treatment Of Unmanageable Psychotic Patients, Armando R. Favazza Dec 1969

Promethazine-Chlorpromazine Combination In The Treatment Of Unmanageable Psychotic Patients, Armando R. Favazza

Henry Ford Hospital Medical Journal

Administering a combination of promethazine and chlorpromazine to patients with a "galloping psychosis" has an antipsychotic and tranquilizing effect which calms them down to a more manageable and less aggressive state. The drugs are chemically similar; promethazine's actions are strongly potentiated in the combination, so large doses must be given under careful supervision. Case histories demonstrate successful short term management of acutely psychotic, aggressive patients who were a danger to themselves and others.


A Preliminary Evaluation Of Azathioprine (Imuran®) In The Treatment Of Multiple Sclerosis, William G. Tucker, K. H. Kapphahn Jun 1969

A Preliminary Evaluation Of Azathioprine (Imuran®) In The Treatment Of Multiple Sclerosis, William G. Tucker, K. H. Kapphahn

Henry Ford Hospital Medical Journal

A theoretical approach to the unknown etiology of multiple sclerosis is presented in this preliminary study which reports the results of empiric treatment with azathioprine. Imuran® therapy produced stabilization of the disease, neurological improvement, and no progress of neurological dysfunction or loss of any regained function. Evidence points toward a viral-induced immunological defect. Abnormal gamma globulins found in the cerebral spinal fluid suggest an immunological etiology.


The Use Of Pickled Wheat In Poultry Feeding, P Smetana Jan 1969

The Use Of Pickled Wheat In Poultry Feeding, P Smetana

Journal of the Department of Agriculture, Western Australia, Series 4

FEEDING fungicides to poultry can result in harmful effects, to the birds themselves, and to their human consumers.

To prevent such effects it is advisable that wheat pickled with fungicides should not be included in poultry rations.


Control Of Insects In Cotton, D G. Shedley, D. L. Hardy, P. J. Michael Jan 1969

Control Of Insects In Cotton, D G. Shedley, D. L. Hardy, P. J. Michael

Journal of the Department of Agriculture, Western Australia, Series 4

Results of two experiments at the Ord Irrigation area in 1968 indicate that farmers may be spending more than necessary to obtain economic control of cotton pests in some seasons.

One experiment clearly demonstrated the relationship between low insect numbers and improved cotton yields—the second indicated that a moderate but well timed spray schedule, especially during the early part of the season, can result in more economic insect control than an intensive spray schedule.


The Transfer Of Hydrogen In The Reduction Of Progesterone, William H. Kersey Aug 1968

The Transfer Of Hydrogen In The Reduction Of Progesterone, William H. Kersey

Loma Linda University Electronic Theses, Dissertations & Projects

Experimental female rats were given daily injections of synthetic estrogens for six months. The effect on rat ovarian 20α-OH-SDH was not definitive. Diethylstilbestrol and 17α-ethynylestradiol caused a significant drop in activity as compared with controls while mestranol caused a slight increase in activity. A synthetic progestin, medroxyprogesterone, had no apparent effect on the activity of the enzyme.

Rat ovarian 20α-OH-SDH was purified fivefold by ammonium sulfate fractionation and chromatography on DEAE-cellulose.

The homogeneity of the enzyme was checked by means of disc gel electrophoresis. At pH 8.2 no significant contamination appeared in the electrophoretic pattern, but at pH 9.0 five …


Some Aspects Of Carbohydrate Metabolism In The Cercariae Of Schistosoma Mansoni Sambon, 1907, A. Eugene Dunham Jr. Jun 1968

Some Aspects Of Carbohydrate Metabolism In The Cercariae Of Schistosoma Mansoni Sambon, 1907, A. Eugene Dunham Jr.

Loma Linda University Electronic Theses, Dissertations & Projects

Cercariac of Schistosoma mansoni were studied for glycogen utilization, uptake of glucose from solution, lactic acid production, and respiration.

Using the anthrone method of determination of carbohydrate, the amount of glycogen used by a single cercaria in 4 hours is determined as 43.2 x 10-4 μg ± 6.6 x 10-4 μg.

Glucose was not observed to have been used from solution under the conditions of the experiment, even in the presence of trehalose. The determinations were made by the Glucostat method.

After deproteinization and desugarization, aliquots of supernatant from cercarial suspensions were analyzed for lactic acid using p-phenylphenol …


Accidental Ingestion Of Anticoagulant Resulting In A Severe Hemorrhagic Diathesis, R. W. Monto, E. R. Williams, T. H. Greidanus, E. J. Van Slyck Jun 1967

Accidental Ingestion Of Anticoagulant Resulting In A Severe Hemorrhagic Diathesis, R. W. Monto, E. R. Williams, T. H. Greidanus, E. J. Van Slyck

Henry Ford Hospital Medical Journal

This case history of a 45-year-old woman, who had been issued Dicumarol instead of Dronactin in a pharmacy-filled prescription, describes an emergency therapeutic program to control hemorrhage with vitamin K, adrenal corticosteroids, and the giving of fresh blood. In a patient with a bleeding disorder, unintentional ingestion of oral anticoagulants is to be suspected if the prothrombin time is markedly elevated, if the patient has been previotisly treated with an oral anticoagulant, or is engaged in a medical or paramedical occupation. Diagnosis is confirmed by finding a deficiency of factors II, VII, IV, and X. and by the presence of …


The Effect Of Schistosoma Mansoni On Free Amino Acid Levels In Mice, Richard D. Tkachuck Jun 1967

The Effect Of Schistosoma Mansoni On Free Amino Acid Levels In Mice, Richard D. Tkachuck

Loma Linda University Electronic Theses, Dissertations & Projects

Free amino acid levels in the blood plasma of mice infected with Schistosoma mansoni Sambon, 1907, were measured at 3, 6, and 9 weeks post-infection with an automatic amino acid analyzer. Significant differences between experimental and control animals occurred at all three time periods. At 3 weeks, asparagine, alanine, citrulline, proline, methionine, and threonine levels all were lower in the infected animals. At 6 weeks, four differences were noted. Alpha-amino-n-butyric acid, ornithine, lysine, and histidine all had lower values in infected animals. At 9 weeks there were 12 differences. Tyrosine, phenylalanine, threonine, serine, proline, citrulline, glycine, alanine, valine, isoleucine, and …

Loma Linda University Electronic Theses, Dissertations & Projects

Three hundred Swiss Webster albino mice three weeks of age were placed on low (8%), medium (24%), high (48%) protein levels and a commercial laboratory animal feed, Purina Chow for various lengths of time: (1) simultaneously with infection, and four weeks thereafter, (2) three weeks before infection and throughout the four-week infection period, and (3) six weeks prior to infection and during the infection period. The protein source was casein. Sixty of the 300 mice used served as noninfected controls, and the other 240 were each infected with 400 washed, suspended Trichinella spiralis larvae obtained from a rat by the …


A Study Of The Effect Of Varying Serum Phenylalanine Levels On Changes In Intelligence Quotient, Darlene Imai Manullang Jun 1964

A Study Of The Effect Of Varying Serum Phenylalanine Levels On Changes In Intelligence Quotient, Darlene Imai Manullang

Loma Linda University Electronic Theses, Dissertations & Projects

Data from thirty medical records of phenylketonuric children under treatment were investigated to determine at which serum phenylalanine level (0-3.9 mg. %, 4-7.9 mg %, 8-11.9 mg. %, greater than 12 mg. %) there would be the greatest increase in intelligence. The children involved in the study were divided into the following groups according to the age dietary treatment was initiated: 0 through 5 months, 6 through 11 months, 12 through 23 months, and over 2 years of age.

Among 6 patients who were placed on the diet during the first 5 months of life, it appears that the optimal …

A Review Of Drug Addiction And A Study Of Its Relation To Carbohydrate Metabolism, Eppie Chung Hartsuiker Jun 1961

A Review Of Drug Addiction And A Study Of Its Relation To Carbohydrate Metabolism, Eppie Chung Hartsuiker

Loma Linda University Electronic Theses, Dissertations & Projects

The specter of addiction eventually involves everyone of the community. It is a three-fold problem of socio-economic, psychological, and physiological factors. The least understood is the physiological or biochemical aspect of addiction.

It has been postulated that an upset in carbohydrate metabolism may be a biochemical cause of addiction. Several avenues were employed to investigate this possible cause of addiction.

  1. A diet survey was conducted and revealed a greater consumption of refined carbohydrates, confections and alcoholic beverages in addicts.

  2. Five-hour oral glucose tolerance tests were performed on 7 addicts and 12 non-addicts. These tests revealed that there were decreased glucose …


Cleansers For The Milking Machine, Department Of Agriculture, Western Australia Jan 1961

Cleansers For The Milking Machine, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

WITH the opening of the flush season dairy farmers should make sure milking machines are working at maximum efficiency.

Machines not working efficiently can cause production losses and damage to cows as well as wasting farmers' time.
