Histologic effects of chronic selenium deficiency in selected tissues of laboratory rats

Creator:: Sprinker, Lucas Harry
Abstract:: The selenium-responsive syndromes and the discovery of Factor 3-selenium focused attention on selenium in metabolism. Two hypotheses have been advanced to explain the metabolic effect of selenium: 1) substitution or sparing of alpha tocopherol, and 2) a primary role in metabolism. The first hypothesis is supported by Scott and Desai,...

The effect of selenium on chemical carcinogenicity in the rat

Creator:: Johnston, Weldon Kearney
Abstract:: One hundred and fifty-one weanling rats of both sexes were fed control diets or diets containing 160 ppm diethylnitrosamine (DEN) or 150 ppm N-2-fluorenyl-acetamide (FAA). The carcinogen level was calculated so that the LD₅₀ should be achieved at about 17 weeks. Each carcinogen treatment was incorporated with three different diet...

A study of the relationship of the use of various drugs to the visual-motor performance of college students

Creator:: Antone, Eugene Joseph, Jr.
Abstract:: The purpose of the study was to compare the visual-motor performance of college students who reported ingestion of certain drugs with those college students who reported no drug ingestion. The study drugs included the following drugs or groups of drugs: tobacco, alcohol, marijuana, LSD, mescaline, barbiturates, and amphetamines. A total...

Pulmonary function of male cigarette smokers compared with lifetime noncigarette smokers

Creator:: Barr, Robert Douglas
Abstract:: The pulmonary function scores of 250 male cigarette smokers were compared with 406 lifetime nonsmokers. A Stead-Wells spirometer was used to obtain forced vital capacity, forced expiratory flow, forced mid-expiratory flow, and forced expiratory volume. All individuals included in the sample were between. the ages of 20 and 49 years....

The visual response of the purple shore crab, Hemigrapsus nudus, to ionizing and non-ionizing radiation

Creator:: Jordan, Neil Michael
Abstract:: Bioelectric responses from the isolated eye of the purple shore crab were measured by the electroretinogram with stimulation by light from wavelengths of 250 to 800 nm, strontium-yttrium-90 beta radiation, 17.5 keV x-radiation, and 3-cm microwaves. Peak sensitivities to light stimulation were found at 350 and 500 nm. These peaks...

The influence of calcium carbonate and clacium gluconate on tetracycline absorption in man

Creator:: Owings, Gary Lee
Abstract:: This experiment was designed to investigate the in vivo effects of calcium ions on tetracycline absorption when oral doses of tetracycline and calcium-containing medications were administered concurrently. Twenty-one human volunteers were selected and divided into three equal-sized groups: Group A, Group B, and Group C. Each volunteer in Group A...

Absorption of benzocaine -³H from semi-solid dosage forms following rectal administration in rats

Creator:: Lorskulsint, Duangchit
Abstract:: The effect of concentration, vehicle and surfactant on the absorption of benzocaine -³H across the rat's rectal mucosa was investigated. Blood radioactivity levels were determined after the application of benzociane -³H containing suppositories and ointments. A wet oxidation method was used for sample digestion. Since the radioactivity counted is the...

Calcium regulation and physiological function in animals exposed to lead

Creator:: Hoffman, Norbert Edward
Abstract:: Tissue distribution studies of calcium and lead in brain tissue of rats were increased subsequent to a single intravenous injection of lead, 10 mg/kg, in the form of lead acetate. Time-course studies demonstrated that brain concentrations of calcium and lead (in terms of wet tissue weight) were found to be...
