The Effects Of Acute Stress On Adrenal Ascorbic Acid Levels, Robert Joseph Collier Jan 1973

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 …


Kidney Of The Frog, Felix Taubman May 1938

Kidney Of The Frog, Felix Taubman

Bachelors’ Theses

The frog has been used exclusively in both high school and college as the main source of experimental biological and zoological studies. Because it is so easily obtained and so finely adapted to our purposes, we chose it as the specimen upon which to do our thesis work. Much has been done experimentally on the kidneys with the frog. The purpose of this thesis is to present a general view of the external and microscopic anatomy of the frog kidney and with this as a groundwork to present the problems of secretion; whether secretion is carried on by the renal …


Chelonian Brain-Membranes, Brain-Bladder, Metapore And Metaplexus, John P. Munson May 1913

Chelonian Brain-Membranes, Brain-Bladder, Metapore And Metaplexus, John P. Munson

Biology Faculty Scholarship

The chelonian brain is not too small to be studied macroscopically. It is easily removed from the skull. Minute surface details and the cell structure can be easily observed.
