The Effect Of Escherichia Coli Endotoxin On The Cat Periapical Tissues, Thomas G. Dwyer

Loma Linda University Electronic Theses, Dissertations & Projects

The periapical tissue reaction to three concentrations of endotoxin solutions and to a sterile saline control solution was examined in six adult cats. The maxillary and mandibular cuspids were isolated and the pulps extirpated with barbed broaches. The four solutions (1, 10, 100 μg/ml endotoxin, and saline) were then injected into the four prepared teeth for each cat and the access cavities sealed with IRM.

At two week intervals, two cats were sacrificed and the specimens removed, while the remaining animals were retreated as previously described. The block tissue sections were radiographed, fixed in 10% buffered formalin, and prepared for …

The Effects Of Temperature And Ph On The Differentiation Of Trypanosoma Lewisi (Kent, 1880) Laveran & Mesnil, 1901, In A Defined Medium, Carolann R. Rosario

Loma Linda University Electronic Theses, Dissertations & Projects

Trypanosoma lewisi is an arthropod-transmitted protozoan parasite found in the bloodstream of rats. In its life cycle it undergoes cellular differentiation. It is primarily found as the trypomastigote form in the rat and as the epimastigote form in the arthropod, the rat flea. Various studies have been done on hemoflagellates to determine the factors responsible for stimulating the differentiation from one form to the other. Included in these factors are pH, temperature, and protein fractions from fetal calf serum. Recent efforts have also been aimed at developing simple or defined media for physiological or biochemical studies on hemoflagellates. The purpose …

Androgen-Induced Immunosuppression, Debra Ann Weyant

Dissertations and Theses

It is well established that females are more immunocompetent than males as evidenced by higher humoral antibody titers, lowered susceptibility to infection, and more efficient graft rejection.

Furthermore, females also exhibit a much higher incidence of autoimmune disease. These observations have led investigators to believe that the male hormonal environment may play a key role in the regulation of immune response. For this reason, this study is concerned with the expression of autoimmunity and of immune function in the mouse.

This study included the New Zealand Black (NZB) mouse strain, as an animal model for human SLE, as well as …

The Effects Of Ph On 5-Oxogluconate Production By Gluconobacter Suboxydans, Neng-Chyang Leu

Masters Theses & Specialist Projects

The metabolism of glucose to 5-oxogluconate by Gluconobacter oxydans subsp. suboxydans (Gluconobacter suboxydans) at different pH values, glucose concentrations and phosphate buffer concentrations was studied. Bacterial growth, gluconic acid accumulation and 5-oxogluconate production were related to both pH and phosphate buffer concentration in the medium.

In media containing 2-3% glucose, 0.3% yeast extract and 0.3 M phosphate buffer, the optimal pH range for the bacterial growth was pH 6.4-7.0; the optimal pH range for gluconate production was pH 6.4-6.8; and the optimal pH range for 5-oxogluconate production was pH 6.6-7.0. Lowering the pH to 6.4 favored gluconate accumulation …

Bacteriological Quality Of Runoff Water From Pastureland, John W. Doran, D.M. Linn

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Runoff from a cow-calf pasture in eastern Nebraska was monitored for total coliforms (TC), fecal coliforms (FC), and fecal streptococci (FS) during 1976, 1977, and 1978. Bacteriological counts in runoff from both grazed and ungrazed areas generally exceeded recommended water quality standards. The FC group was the best indicator group of the impact of grazing. Rainfall runoff from the grazed area contained 5 to 10 times more FC than runoff from the fenced, ungrazed area. There was little difference in TC counts between the two areas, but FS counts were higher in runoff from the ungrazed area and reflected the …

Cell Mediated Immunity By Cytotoxicity Assay And The Effect Of Corynebacterium Parvum And Radiation On Mice Bearing Herpes-Induced Tumors, Robert B. Stagg

Loma Linda University Electronic Theses, Dissertations & Projects

Cell mediated immune (CMI) cytotoxic reactivity of Balb/c mice against H238 cells, a Herpes simplex virus (HSV) Type 2 - induced sarcoma, was measured by the ¹²⁵IUdR release assay. The Balb/c mouse response to the growing HSV-induced tumor, treated with radiation and , was measured by survival rate, tumor growth and immune cytotoxicity of spleen and peritoneal exudate cells (PEC) as determined by ¹²⁵IUdR release assay. Subcutaneous (s.c.) inoculation of 1 x 10⁶ H238 cells (high dose) produced progressive tumor growth while s.c. inoculation of 1 x 10⁴ H238 cells (low dose) produced no tumors. A …

Estimation Of The Pantothenic Acid Content Of Foods Using A Microbiological Assay And A Radioimmunoassay, Joan Howe Walsh

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Seventy-five processed and prepared foods commonly consumed in the United States were analyzed for pantothenic acid. The foods were analyzed using the traditional microbiological assay for the vitamin and using a new radioimmunoassay (RIA).

The preparation of food sample extracts for both assays was modified. After the food samples underwent enzyme hydrolysis, the food-enzyme mixture was dialyzed to obtain a clear extract for use in the assays. Previously, the food-enzyme mixture was poured through filter paper for clarification.

A very high correlation (r²= .937) between the results from the RIA and the microbiological assay was found. There was …

Sodium And Potassium Nutrition Studies Of Halogeton Glomeratus (M. Bieb) C.A. Mey, Ali A. Alhelal

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Halogeton glomeratus (M. Bieb) C.A. Mey when grown in nutrient solution, caused the solution pH to decrease very rapidly as plants increased in size, especially during the fifth week of growth. This might be attributed to hydrogen ion exchange for cations. Also, the cation uptake, especially K and Na, may exceed that of the major anions. The control of pH is effective in increasing shoot weights markedly.

In general there was no difference between plants grown at the same NaCl concentration at low and high relative humidity. An increase in plant size, shoot weights, leaf length and diameter was detected …

Motility Of The Microtubular Axostyle In Pyrsonympha, George M. Langford, Shinya Inoué

Biology - All Scholarship

The rhythmic movement of the microtubular axostyle in the termite flagellate, Pyrsonympha vertens, was analyzed with polarization and electron microscopy. The protozoan axostyle is birefringent as a result of the semi-crystalline alignment of approximately 2,000 microtubules. The birefringence of the organelle permits analysis of the beat pattern in vivo. Modifications of the beat pattern were achieved with visible and UV microbeam irradiation. The beating axostyle is helically twisted and has two principal movements, one resembling ciliary and the other flagellar beating. The anterior portion of the beating axostyle has effective and recovery phases with each beat thereby simulating the flexural …

In Vitro Experiments On Totipotency Of Dacus Carota, Karl L. Ruser

Journal of the Minnesota Academy of Science

The intent of this project was to induce the totipotency of carrot cells in tissue culture. The information gathered would be applied to work with woody plants. Differentiated cells removed from the root were cultured in vitro using a modified White's medium. Callus was initiated and successfully sub cultured. Roots and the production of chlorophyll have been initiated in the cultures. Because some specialized equipment and facilities for tissue culture were not available at the beginning of the project, it took considerable time to gather and improvise them. A roller tube culture mixer was constructed, using the mechanism from a …
