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 …

Molecular Weight Determinations Of Some Salmonella Potsdam Bacteriophage Dna's, Winston H. Richards

Loma Linda University Electronic Theses, Dissertations & Projects

Two group A phages, P9c/2 and P4/2, were studied. Their density, sedimentation velocity, and biochemical properties were compared. Their densities were determined by density gradient centrifugation in 38.3% cesium chloride. Sedimentation velocity was used to determine their molecular weights. To accomplish this, the DNA of P9c/2 and P4/2 was labeled with tritium and T₂ DNA, labeled with ³²P, was used as a standard. The DNA of P9c/2 and P4/2 was separately mixed with T₂ DNA and centrifuged in a 0-15% sucrose gradient. The molecular weights were calculated using the formula D₂/D₁= (M_{2 …}

Algal Growth And Decomposition: Effects On Water Quality, Edward G. Foree, John S. Tapp Jr.

KWRRI Research Reports

The chemical composition of algae grown in batch culture depends mainly on environmental conditions, nutrient availability, presence of predators, cell age, and species. The effects of nutrient availability and cell age on the composition of three unialgal cultures (algae + bacteria) and one hetergeneous culture (algae + bacteria + microscopic animals) were evaluated. The cultures were grown in batch culture under both nutrient-abundant and nutrient deficient conditions and the changes in compositions were observed. Luxurious uptake where nutrients are incorporated into cellular protoplasm at levels greater than those necessary for growth, and super-luxurious uptake, where some nutrients are stored rather …

A Study Of The Bacteriological Effectiveness Of Oral Thermometer Procedures In Three Selected Hospitals, Esther Mae Rose

Loma Linda University Electronic Theses, Dissertations & Projects

Because pathogens such as streptococcus and staphylococcus have been transferred in many hospitals, the source of the infections is of concern to doctors, nurses, and other medical personnel. As shown by the review of literature, good techniques are necessary to stop the spread of disease.

It was the purpose of this study to investigate one facet of patient safety by: (1) the culture of thermometers ready for use in three selected hospitals; (2) to determine the effectiveness of the Group, Individual, and Central Supply methods of disinfection currently practiced in the three selected hospitals.

The method for the experiment of …
