The Effects Of Crowding On The Diurnal Ascorbic Acid Levels Of Albino Rats, Mary Jo Barr
The Effects Of Crowding On The Diurnal Ascorbic Acid Levels Of Albino Rats, Mary Jo Barr
Masters Theses
The adrenal physiology of the albino rat was studied through the measurement of adrenal ascorbic acid levels. A cyclic phenomenon was observed which follows the diel periodicity of the animal. Ascorbic acid values were found to be characteristically higher in males than in females. A similar difference was also seen in populations divided into young animals (body weight less than 175 grams) and old animals (body weight greater than 175 grams). Crowding, induced by manipulating the area of cage space per gram of body weight, was observed to be a definite stressor and caused the adrenal ascorbic acid levels to …
A Study Of Organochlorine Insecticides In Freshwater Crayfish -- Analytical Problems And Biomonitoring Survey, Robert C. Vanderjack
A Study Of Organochlorine Insecticides In Freshwater Crayfish -- Analytical Problems And Biomonitoring Survey, Robert C. Vanderjack
Masters Theses
Crayfish were collected from 3 sites on Polecat Creek, Coles County, Illinois in early spring, early summer, and late summer of 1972. Pesticides were extracted from the crayfish tissue in a one step procedure utilizing a Florisil elution column. Analysis was by electron capture gas chromatography. Pesticide residues in the nannogram range were analyzed and background contamination was an important consideration. Sources of background contamination were investigated and teflon stopcocks, Florisil, and residues on “cleaned” glassware were found to be major contamination sources. Distilled water used in flushing glassware should also be considered a potential contamination source.

Seasonal Variation In The Tubular And Interstitial Areas Of The Testes In Sternotherus Odoratus L., Robert Hans Spaet
Seasonal Variation In The Tubular And Interstitial Areas Of The Testes In Sternotherus Odoratus L., Robert Hans Spaet
Masters Theses
Seasonal changes within the tubular and interstitial areas of the testes in Sternotherus odoratus are investigated, histologically and histochemically. Forty specimens were collected in Illinois, Tennessee and Louisiana between May, 1969 and August, 1972.
Many of the histological and macroscopic observations made by Risley (1938) on the spermatogenic cycle of S. odoratus in Michigan are confirmed. Contrary to his findings, fluctuations in interstitial cell nuclear diameters are observed during spermatogenesis. Greatest diameters coincide with what Risley has considered " . . . period of most active breeding." Sertoli cell nuclear diameters undergo similar fluctuations being greatest during spring breeding and …
Morphological And Physiological Effects Of 2,4-D On Gram-Negative And Gram-Positive Bacteria, John H. Rupnow
Morphological And Physiological Effects Of 2,4-D On Gram-Negative And Gram-Positive Bacteria, John H. Rupnow
Masters Theses
Manometric, spectrophotometric, photomicrographic and quantitative biochemical techniques were employed to determine the morphological and physiological effects of 2,4-D on Gram-positive and Gram-negative bacteria.
The growth and motility of Gram-positive bacteria appeared to be more adversely affected than the growth and motility of Gram-negative species. The terminal oxidation, lysis, and chain length of both Gram-positive and Gram-negative bacteria did not appear to be affected by the concentrations used. The average cell size of both Gram-positive and Gram-negative bacteria was observed to increase after exposure to 1000 ppm 2,4-D. The normal leakage of amino acid and ultraviolet light absorbing cell constituents appeared …
A Study Of Soil Amoebae Infective To Mice, Pamela Mcdaniel
A Study Of Soil Amoebae Infective To Mice, Pamela Mcdaniel
Masters Theses
On January 1, 1973, 10 soil samples were collected from areas in Coles County, Illinois, in an effort to isolate soil amoebae. All 10 soil samples were cultured on bacto-nutrient agar and colonies of amoebae genera isolated were Acanthamoeba and Hartmannella. Amoebabacteria cultures prepared from soil isolates were injected into each of 10 adult mice which were sacrificed at the end of the nine days and examined for evidence of infection and pathogenicity. Lesions were observed in two mice and amoebae cysts and bacterial colonies were present in nine mice. Amoeba-bacteria cultures were purified using streptomycin antibiotic discs and …
Morphometric Variation In Aphelenchus Avenae Bastian, 1865 With Varied Nutrition And Time, John P. Kline
Morphometric Variation In Aphelenchus Avenae Bastian, 1865 With Varied Nutrition And Time, John P. Kline
Masters Theses
The effect of varied time, nutritional media, and species of fungus on taxonomic characters (L, a, b1, c, and V) of Aphelenchus avenae was investigated. The effect of these ecological conditions on morphometrics was variable; however, these characters varied significantly with increased time, decreased nutritional media, and species of fungus. The greatest number of morphometric changes occurred with increased time, and the fewest with species of fungus. With changing environmental conditions, “V” values were the most stable character.
Gastro-Intestinal And Abdominal Helminths Of White-Tailed Deer (Odocoileus Virginianus) From Carroll And Jo Daviess Counties In Northern Illinois, Jeffrey Joseph Hodge
Gastro-Intestinal And Abdominal Helminths Of White-Tailed Deer (Odocoileus Virginianus) From Carroll And Jo Daviess Counties In Northern Illinois, Jeffrey Joseph Hodge
Masters Theses
Forty-four white-tailed deer shot by hunters in November and December, 1971, in Carroll and Jo Daviess counties in northwestern Illinois were necropsied for gastro-intestinal and abdominal helminths. Five species of gastro-intestinal nematodes were found: Gongylonema pulchrum, Ostertagia odocoilei, Haemonchus contortus, Trichuris ovis and Nematodirus sp. Setaria yehi, a filiariad nematode, was found in the abdominal cavity. Moniezia benedeni was the only cestode found. No trematodes were recovered. Differences in numbers and kinds of parasites found in northern Illinois and southern Illinois are discussed. Prevalence increased with host age for certain species of parasites and decreased or …
The Effects Of Acute Stress On Adrenal Ascorbic Acid Levels, Robert Joseph Collier
The Effects Of Acute Stress On Adrenal Ascorbic Acid Levels, Robert Joseph Collier
Masters Theses
The diurnal rhythm of adrenal ascorbic acid (DAR) displays an inverse relationship to the diurnal rhythm of circulating levels of plasma corticosteroids. Alloxan monohydrate, 175 mg/kg body weight was given subcutaneously to albino rats to determine the effect of the diabetic state on the DAR. A total of 200 female albino rats were divided into two study groups. Study Group I was composed of 150 animals divided into populations of 15, each including 3 controls. Study Group II was composed of populations of 5, each group containing all controls or all alloxinated rats. The populations of 15 were sacrificed at …
A Medicated Dry Foam For Local Therapy In Infected Burns, Patrick Nicholas Catania
A Medicated Dry Foam For Local Therapy In Infected Burns, Patrick Nicholas Catania
University of the Pacific Theses and Dissertations
Local burn therapy usually includes the application of medicated ointments and dressings in order to minimize and eradicate infection. As this approach to local therapy may present problems regarding application and removal techniques, it was the purpose of this study to formulate a topical dosage form that may be applied to denuded areas of the skin without inunction. Using the concept of topical films, a dosage form was formulated that is highly water soluble, flexible , and adherent to both denuded and intact areas of the skin.
Anticoagulant Half-Life Of Heparin In Human Subjects With Normal And Impaired Renal Function., Paul James Perry
Anticoagulant Half-Life Of Heparin In Human Subjects With Normal And Impaired Renal Function., Paul James Perry
University of the Pacific Theses and Dissertations
Numerous investigators have noted that individuals vary widely in their response to the anticoagulant, heparin. Animal model3 have suggested that patients with depressed renal function would be expected to clear heparin from the blood at a slower rate than patients with normal renal function.
Utilizing the Activated Coagulation Time clotting test, a method was developed to determine the anticoagulant half-life of heparin. The study calculated the half-life of heparin in a group of individuals with normal renal function and a population of patients in chronic renal failure. Intravenous heparin doses of 0,3 units/ml and 0.6 units/ml of blood were administered …
