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 …

Food, Nutrition, And Health, Problems And Prospects, D. K. Salunkhe

Faculty Honor Lectures

Food, nutrition, and health - and their complex interrelationships - are necessities of life. Basically, nutrition depends on food; health depends on nutrition. Everyone needs to have enough good quality food to sustain himself. Satisfying that need on a world basis must be of concern to each of us.

Although accurate data are lacking, it is estimated that more than two-thirds of today's world population is afflicted by hunger and/ or malnutrition. Almost 300 million children are suffering physical and, probably, mental damage because of insufficient food. This evidence points to one of two conclusions: we have either too many …

Two series of experiments were conducted in order to determine the effects of diet on neutrophilic phagocytosis. The first series was designed to determine the effects of varying amounts of oral glucose on phagocytosis. Blood samples from 6 to 8 subjects were drawn at fasting, and at various time periods following ingestion of 12.5, 25, 50, 75, and 100 grams of glucose. In the second series of experiments, blood samples were taken from 11 subjects after an overnight fast and 2 hours following ingestion of one of 4 different liquid diets, which included the following: the meal (I), consisting of …

The Bactericidal Activity Of Human Polymorphonuclear Leukocytes Before And After The Ingestion Of Glucose, Carolyn Ann Corder

Loma Linda University Electronic Theses, Dissertations & Projects

The bactericidal test has been used to determine whether the consumption of concentrated carbohydrate affects the ability of human leukocytes to destroy bacteria. Subjects were given a dose of 100 grams of glucose. Two hours later a blood sample was drawn and incubated with Staphylococcus epidermidis for 120 minutes. There was no significant difference in the bactericidal activity of leukocytes of blood two hours following the ingestion of glucose from the bactericidal activity of fasting blood. A count done simultaneously with the bactericidal tests of the average number of single cocci engulfed per polymorphonuclear leukocyte showed a slightly lower phagocytic …

Effects Of Cocaine, Nicotine And Diet On Voluntary Alcohol Consumption In Rats, Zaida Raquel Cordero Loayza

Loma Linda University Electronic Theses, Dissertations & Projects

The consumption of alcohol is a problem not only in this country (U.S.), but also in many other places in the world. Thus we find the Indians in Peru, Bolivia and other neighboring countries (Ecuador and northern part of Argentina) consuming alcohol to the point that they become alcoholics, in addition to this they also chew coca leaves, plant from which cocaine is extracted.

In an effort to establish the cause for this behavior, we put Sprague-Dawley albino rats on either a poor or good basal diet. Once every other day the rats were injected with a solution of cocaine. …

Manufacture Of Monterey Cheese From Preacidified Milk, Faisal O. Mohamed

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Whole milk acidified to pH 5.3 with hydrochloric acid was used for the manufacture of Monterey cheese. The milk was inoculated with one and one-half percent lactic starter and set with 12.5 ml rennet per 1000 pounds of milk. Normal washing treatments resulted in cheese with moisture in excess of 44 percent. Moisture content was brought below 44 percent by using wash water at a temperature such that the water-curd-whey mixture was 35 C. The pH of cheese made by preacidification was all between 5.21 and 5.09. No acid defects were encountered. Preacidification eliminated chance of spoilage or losses caused …

Effects Of X-Ray Induced Achlorhdria On The Utilization Of Dietary Calcium And Iron From Different Salts By Rats, Reid Scott Holbrook

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dietary calcium has been classified as one of the minerals frequently limiting in the American diet (FAO, 1962) . Bone demineralization has been observed as a result of calcium deficient diets (Salomon et al., 1972), partial gastrectomies (Eddy, 1971) and inadequate hormonal balance (Albright et al., 1948). Although bone demineralization, or osteoporosis, has been attributed to many factors, the interrelationship of gastric acidity and the utilization of dietary calcium may be a key to the etiology of osteoporosis.

Eighty weanling male albino rats were divided into eight groups. All animals had their stomachs exposed through a mid-line incision. Control rats …

Distribution Of Milk Clotting Enzymes Between Curd And Whey And Their Survival During Cheddar Cheese Manufacture, David G. Holmes

A Study Concerning Sources Of Information And Knowledge About Fluoride In Logan, Milford, And Helper, Utah, Marilyn Lorraine Geddes

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A considerable amount of research has been conducted concerning the characteristics of people who are in favor of fluoridation. However, there is little information available as to what the electorate really knows about fluoride when they are forced to vote on this scientific issue.

Thus, the objectives of this study were to determine the general public's level of knowledge about fluoride, to discover what sources of information have been the greatest influence on their opinion and knowledge about fluoride, and to estimate the level of participation of dentists, general practitioners, pediatricians, and gynecologists in the education of Utahns about the …

Nutritional Anemias In Selected Countries, Wun-Yuan Mei

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Blood is a constantly changing, highly complex tissue which is concerned with the transport of cell nutrients, the elimination of wastes, and the maintenance of chemical equilibrium. The mature red blood cell takes about seven and half days to develop, then has a life cycle of 120 days. Many factors are involved in this complicated process. Many nutrients are required for the frame-work of the red blood cells and in the hemoglobin within these cells.

Anemia is a condition in which there is a reduction in the total circulating hemoglobin. Anemias may be described biochemically in terms of lowered hemoglobin …

The Development Of An Improved Milk Substrate For Rennet Coagulation Assay On An Automatic Clot-Timer, Mark Brimhall Stevens

Lot Feeding Sheep In Sheds, H E. Fels, B. Malcolm

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

The need to gather and hold sheep for slaughter or live shipment led a West Australian company!, with the Department of Agriculture, to investigate the use of sheds for short term lot feeding of sheep. Preliminary examination suggested that feedlot sheds connected by a sheep footpath to the abattoirs, railway or saleyards could be cheaper as well as more practicable than continued use of holding paddocks.

The first week or two are commonly the most difficult in lot feeding sheep or cattle. Long-term indoor lot-feeding is a normal practice in some overseas countries but we did not know whether untrained …

Nitrogen For Pastures, Department Of Agriculture, Western Australia

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

The use of nitrogen (N) fertilisers on cereals has long been recognised and accepted as an economic farm practice. It is only more recently that the use of fertiliser nitrogen has been considered for pasture and fodder production, mainly on wholemilk and butterfat farms in the South-West. The high quality feed produced may be substituted for concentrates or conserved fodder. Large increases in seasonal production have been reported.

Because nitrogen fertiliser is expensive, has a short-term effect, and can affect the clover content of pastures, a series of field experiments were conducted in 1973 to examine the role of nitrogen …

Effects Of Dietary Factors And Morphine Administration On Voluntary Alcohol Consumption And Dopamine Metabolism In Rats, Claudia Smithson

Loma Linda University Electronic Theses, Dissertations & Projects

The effect of diet and dietary additives on voluntary alcohol consumption in male Sprague-Dawley rats was studied. Alcohol intake measured weekly and reported as ml of a 10% solution ingested per 100 grams body weight. A four week pre-experimental period was designed to determine individual tendencies to drink and thus to eliminate the high and low drinkers from the study. No difference was found in alcohol intake with either starch or sugar as the carbohydrate source; however, there was a greater weight gain ( p < .025) in those animals consuming sugar-based diets. Rats on poor-quality diets containing minimal amounts of vitamins and minerals continued to gradually increase alcohol consumption during the study. This diet, supplemented with coffee, caused the greatest significant increase in alcohol intake and the lowest weight gains. Addition of coffee to the diets significantly increased alcohol consumption (p< .005) but decreased growth rate (p < .0005) . However, when the poor quality diets were supplemented with vitamins and minerals, alcohol consumption was reduced by about 50% (p < .005) and weight gain was significantly increased (p < .0005).

The daily intraperitoneal administration of morphine sulfate significantly decreased alcohol intake (p < .02) and the per cent of total fluid consumed as alcohol (p < .02) but did not effect water consumption.

An attempt was …

Assay And Control Of Staphylococcal Enterotoxin A Development In Cheddar Cheese Slurries, Niranjan R. Gandhi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Attempts were made to adapt the microtiter hemagglutination inhibition assay technique for the assay of enterotoxin A. The presence of a potent hemagglutinin in crude and partially purified preparations and the instability of sensitized erythrocytes prevented its use for routine analysis of enterotoxin from culture media and foods.

A capillary tube immunological assay was developed in which 1 μ g of enterotoxin/ml was detected in less than 1 hr . Interfacial reaction of antisera and enterotoxin solutions in a 1 mm internal diameter capillary tube allowed rapid detection and serological typing of enterotoxins.

Staphylococcus aureus growth and enterotoxin A development …
