Lymphocyte Subpopulations And Other Laboratory Parameters In Patients With The Acquired Immune Deficiency Syndrome (Aids) And Related Conditions, Steven C. Shivers
Retrospective Theses and Dissertations
Patients with Acquired Immune Deficiency Syndrome (AIDS), AIDS-Related Complex (ARC) and other high-risk individuals were evaluated for lymphocyte subsets and serum levels of IgG, IgA, IgM, complement C3 and C4, B2-rnicroglobulin, circulating immune complexes and antibodies to HIV (1). Patients with other immunologic diseases not related to AIDS and healthy individuals not at risk for AIDS were also included in the study. AIDS-related patients overall showed significant (p < .05) relative and absolute decreases helper/inducer T cells, and relative and absolute increases in suppressor/ cytotoxic T cells, resulting in dramatic decreases in helper to suppressor ratios. Relative decreases in total T cells and increases in B cells and natural killer (NK) cells were also observed in some AIDSrelated patients. Four patients not at risk for AIDS had borderline and possibly false positive HIV antibody results. Antibody levels in one of these patients gradually changed to negative after a period of a few weeks. AIDS-related patients overall were also found to have significant (p < .05) increases in serum levels of imrnunoglobulins, B2-microglobulin, and circulating immune complexes. Significant changes in serum levels of Complement C3 and C4 were not observed.
Age, Growth, And Movement Patterns Of The Atlantic Stingray, Dasyatis Sabina, In A Florida Coastal Lagoon System, Thomas Henry Schmid
Age, Growth, And Movement Patterns Of The Atlantic Stingray, Dasyatis Sabina, In A Florida Coastal Lagoon System, Thomas Henry Schmid
Retrospective Theses and Dissertations
Age, growth rates, and patterns of movement were studied in the Atlantic stingray, Dasyatis sabina, in the Indian River lagoon system in east central Florida. Age was estimated using the growth rings on the vertebral centrum and tretacycline marking. Tetracycline injections produced clear readable rings in all pups, but failed to be incorporated into the centra of adults. Females possess more centrum rings than males, but annual periodicity could not be verified. Growth rates were determined from aquarium held pups and adults and from tagged and recaptured animals. Males appeared to reach maturity in about two years, females in slightly …
Variation In Female Somatic Condition And Its Relationship To Reproduction In The Sailfin Molly, Poecilia Latipinna (Pisces: Poeciliidae), Richard Eugene Smith
Variation In Female Somatic Condition And Its Relationship To Reproduction In The Sailfin Molly, Poecilia Latipinna (Pisces: Poeciliidae), Richard Eugene Smith
Retrospective Theses and Dissertations
Seasonal and gestational variation in the somatic and reproductive condition of females was determined for two east-central Florida populations of the livebearing fish Poecilia latipinna. Females were sampled monthly between January 1985 and January 1986 at Badge Station (BDGST) and Titusville Ditch (TDTCH) study sites. In addition, collections were made at approximately 8 day intervals in April and August. Somatic condition was determined by calculating index values for dry weight (somatic tissue minus water), lipid, and protein from overall regression equations relating these components to female body size. Significant seasonal variation in somatic condition existed within the two study sites. …
