Effect Of Toxaphene On Collagen Synthesis In Fish Tissue: Organ Culture Studies And Prolyl Hydroxylase Activity Assay, Charles Franklin Luke May 1981

Effect Of Toxaphene On Collagen Synthesis In Fish Tissue: Organ Culture Studies And Prolyl Hydroxylase Activity Assay, Charles Franklin Luke

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Toxaphene is reported to cause defects in the collagen of fish. Chronic exposure to toxhaphene weakens the backbone of fish by decreasing the amount of collagen and usually increasing the amount of calcium in the bone which results in a more brittle and fragile bone.

We investigated the possible direct action of toxaphene on collagen synthesis by exposing vertebral and swim bladder organ cultures obtained from unexposed rainbow trout (Salmo gairdneri) fingerlings to the same lot of toxaphene found to cause this defect in vivio. Collagen produced by these organ cultures was measured by: (1) total 3 …


Examination Of The Effect Of Physical Exercise On Metabolic Control In Type I Insulin-Dependent Youth With Diabetes Mellitus, Gayle Ann Brazzi May 1981

Examination Of The Effect Of Physical Exercise On Metabolic Control In Type I Insulin-Dependent Youth With Diabetes Mellitus, Gayle Ann Brazzi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There is evidence for the importance of physical exercise balanced with diet and insulin therapy in the treatment and control of Type I insulin-dependent diabetes mellitus. Recent attention in the literature has focused on the once neglected component of treatment--exercise. A well-controlled exercise state is generally believed to be beneficial for the individual with diabetes. Limited studies are available on the effect of exercise on long-term metabolic control. Before exercise levels can be professionally prescribed for a given population of youth with diabetes, current exercise patterns should be evaluated as to the effect on long-term metabolic control.

It is the …
