Physiology of the corpus luteum of the rat

Creator:: Shumake, James Michael
Abstract:: Rat luteal cells from functional and non-functional corpora lutea (corpora lutea rendered non-functional by hypophysectomy) were preserved for light and electron microscopy in Bouin's and glutaraldehyde-osmium fixation respectively. Material for electron microscopy was dehydrated with ethanol, embedded in Araldite and stained with lead hydroxide or uranyl acetate-lead citrate. Examination of...

The algal symbionts of the solitary green sea anemone Anthopleura xanthogrammica

Creator:: Hartman, Michael Colyn
Abstract:: The anemone Anthopleura xanthogrammica varies in color from bright green to muddy brown. However, individuals found in caves are white. White specimens of Anthopleura xanthogrammica collected from dark caves along the Oregon coast were subjected to various experiments to determine if these cave dwelling animals carried any cells of the...

An ultrastructural study of tentacle development in Cordylophora lacustris

Creator:: O'Rand, Michael G.
Abstract:: Morphological changes which occur during tentacle formation have been described in the colonial athecate hydroid Cordylophora lacustris. These changes involve an outpocketing of mesoglea into a finger-like extension of the hydranth. Gastrodermal cells line the inside of this extension of mesoglea while ectodermal cells cover the outside. Electron micrographs reveal...

The water economy of the Sage Sparrow, Amphispiza belli nevadensis (Ridgway)

Creator:: Moldenhauer, Ralph Roy
Abstract:: This study investigated several physiological aspects of the water economy of the Sage Sparrow, Amphispiza belli nevadensis,as they relate to the ability of this species to inhabit xeric desert environments. When maintained in captivity on a dry diet without drinking water, Sage Sparrows gradually lost weight and died. During the...

Cytophotometric determinations of nuclear DNA content in tissues of the wax moth larva, Galleria mellonella Linnaeus

Creator:: Longo, Frank J., 1939-
Abstract:: The present study was undertaken to determine, by measurement of nuclear DNA, the degrees and frequencies of ploidy in the last larval instar of the moth Galleria mellonella Linnaeus. While such data have been amassed for a wide variety of vertebrate tissues, few studies have been concerned with invertebrates and...

Transmission of "Salmon Poisoning" disease to dogs by Nanophyetus salmincola eggs

Creator:: Nyberg, Peter Albert
Abstract:: The presence of the etiologic agent of "salmon poisoning" disease, Neorickettsia helminthoeca, was demonstrated in eggs of the trematode vector, Nanophyetus salmincola. Three dogs were given 100,000 and one dog 82,000 ground fluke eggs by intraperitoneal injection. The four animals developed "salmon poisoning" disease and died. One of these dogs...

Osmotic and ionic regulation in the earthworm Lumbricus terrestris

Creator:: Dietz, Thomas Howard
Abstract:: Earthworms are capable of osmotic and ionic regulation while living in a dilute balanced salt solution. When transferred from soil to pond-water (PW) their body weight increases by 15 percent due to a net uptake of water. This results in an initial dilution of the coelomic fluid (CF). Subsequently, Na...

A study of the effect of 1,2-alpha-methlene-6-chloro-delta-4, 6-17-alpha-hydroxy progesterone acetate on the adult male rat including changes in the cell associations of the germinal epithelium

Creator:: Lin, Samuel
Abstract:: SH 714 (1, 2-alpha-methylene-6-chloro-delta-4, 6-17-alphahydroxyprogesterone acetate) synthesized by Schering AG is an highly antiandrogenic, nonestrogenic compound. The present investigation was undertaken to determine the compound's effect upon the cell associations of the germinal epithelium in the mature rat. From germinal epithelium for this dosage level of SH 714 was exhibited...

The effects of versene on dividing sea urchin eggs

Creator:: Hanson, James Charles
Abstract:: Developing sea urchin eggs (Strongylocentrotus purpuratus), reared at 15° C, were subjected to single 15-minute treatments with disodium versenate in calcium-free sea water, applied at 10-minute intervals, from 4 minutes after insemination to the second cleavage. These versene pulses produced specific degrees of retardation in the mitotic process and delayed...
