Physiological Parameters During Perfusion Fixation Of The Rat Central Nervous System For Electron Microscopy, Everet W. Witzel

Loma Linda University Electronic Theses, Dissertations & Projects

In an attempt to elucidate the problem of extracellular space within the cerebral cortex of the rat, several physiological parameters were analyzed during perfusion fixation with glutaraldehyde and acrolein for electron microscopy. These parameters were electroencephalography, electromyography, electrocardiography, cerebrospinal fluid pressure, impedance of cerebral cortex, perfusion pressure, and flow rate of the perfusate.

The first portion of this investigation dealt with the problem of asphyxiation of tissues during fixation. A substituted blood containing fluorocarbon which was oxygenated served as the means to study this problem. The last portion of this investigation dealt with buffers and molecular size in relationship to …

The Hyobranchium And Throat Myology Of The Adult Ambystomidae Of The United States And Northern Mexico, John E. Krogh, Wilmer W. Tanner

Brigham Young University Science Bulletin, Biological Series

The 16 species and subspecies of the Ambystomidae of the United States are placed into six groups according to their throat morphology as follows: The Dicamptodon group, the Rhyacotriton group, the A. Annulatum–A. cingulatum group, the A. gracile-A. jeffersonianum-A. mabeei-A. macrodactylum-A. maculatum group, the A. talpoideum group, the A. opacum-A. texanum group, and the A. rosaceum-A. t. tigrinum-A. t. melanostictum-A. t. nebulosum group. Dicamptodon appears to be the most primitive group and Rhyacotriton the most specialized. Based on the morphology of the throat region it is suggested that A. rosaceum be placed in the tiger salamander group as a subspecies …

Selected Factors Related To Ability To Regain Bladder Function Following Indwelling Catheterization, Jongkolnee Padmasiri

Loma Linda University Electronic Theses, Dissertations & Projects

This exploratory retrospective study was designed to evaluate selected factors, including the ability to regain bladder function related to post indwelling urethral catheterization in an acute general hospital population.

The records of 107 patients who met the study criteria became the study population. These patients had three-way urethral catheters, continuous antibacterial irrigation and closed drainage system. Twenty patients died (19 percent) before the catheter was removed. Of the 87 patients who were alive, 37 percent (32 patients) had in-adequate bladder function. Of these 32 patients, no attempt was made to remove the catheter from 15 prior to their hospital discharge. …

Understory Characteristics Related To Site Quality For Aspen In Utah, James H. Warner, Kimball T. Harper

Brigham Young University Science Bulletin, Biological Series

An analysis has been made of the basic ecology of aspen forests of the mountainous areas of Utah and northern Arizona. Forty-nine study areas have been examined in respect to density, height and age of the tree cover, tree reproduction, and composition and biomass production of the understory. A graphic model of interspecific assocations among prevalent understory species has been prepared by a cluster-analysis procedure based on presence and absence of species in 1,225 small quadrats (0.25 m²) uniformly distributed among the 49 stands. The model separates species of relatively stable as opposed to rapidly seral aspen forests. …

A Study Of Thoracic Skeletomusculature In Peracarida (Crustacea), Donna R. Gill

Masters Theses

Two species of peracarid malacostracans, a mysid, Neomysis americana, and an oniscid isopod, Trachelipus cf. rathkei, were used to study the skeletomusculature system. Serial sections, whole mounts, and gross dissections were made. Coxal promotors and remotors and basal adductors and abductors were the muscle groups examined.

The promotor and remotor muscles of N. americana were found to be numerous, well developed, taking origin primarily from the dorsal thoracic wall, and extending nearly ventrally to insert in the coxa; the adductor muscle and two abductor muscles are weakly developed. The coxa in T. cf. rathkei is incorporated completely …

An Ultrastructural Study Of Tubules, Vasculature And Interstitium In Human Renal Homografts, Marilyn Hatch

Theses and Dissertations

In recent years renal homotransplantation has become more frequently used in the treatment of terminal renal disease in man. By carefully selecting donors with the aid of tissue compatibility tests and employing immunosuppressive drugs, these transplants have become increasingly more successful. It is true, however, that even with good tissue match-up and drug treatment rejection episodes occur, frequently within the first two-postsurgical weeks. The majority of these rejection crises may be reversed by increasing drug dosages and occasionally applying x-irradiation to the area of the transplant. In other cases rejection by the recipient is responsible for cessation of function of …

The Effects Of Desoxycorticosterone, Hydrocortisone, And Prednisone On Myogenesis In Vitro, Gregory K. Nienaber

Masters Theses

In order to obtain proper muscle development in tissue culture, certain conditions must prevail. There is a delicate balance of factors, and elimination of even one of these factors leads to poor and improper development. Muscle cells grown in the absence of fibroblasts usually fail to differentiate. Therefore, proper development depends upon the presence of two cell types: myoblasts and fibroblasts. Investigators have demonstrated that the fibroblasts are necessary in that they produce collagen which is necessary for proper muscle development. The present study has shown that desoxycorticosterone, hydrocortisone, and prednisone at concentrations of 10, 1, and 0.1 ug/ml of …

The Anatomical Relationships, Ultrastructure, And Function Of The Pineal Gland In Some Common Laboratory Rodents, Joseph Chester Gregorek

Theses and Dissertations

The pineal complex of rodents is made up of a pineal organ which developmentally always originates from the area between the habenular and posterior commissure and a pineal sac which is continuous with the choroid plexus of the third ventricle. This sac appears to be identical to the choroid plexus at both light and electron microscopic levels. The pineal sac abuts the deep and superficial pineal organs of the golden hamster. In the PET mouse, gerbil, kangaroo rat and Chinese hamster, the sac is contiguous with only small areas of pinealocytes. This sac never abuts true pineal parenchyma in the …

Brigham Young University Science Bulletin, Biological Series

A Cretaceous (Cenomanian) flora from the Dakota Sandstone Formation near Westwater, Grand County, Utah contains an admixture of ferns and angiosperms. The ferns of this flora are representative of an older Jurassic-Wealden vegetational type, whereas the angiosperms are typical of the modern vegetational type. Species of Gleichenia and Matonidium and Astralopteris coloradica represent the dominant forms in this flora.

The Westwater flora contains fourteen genera including nineteen species and one variety. New species described from this flora include Asplenium dakotensis, Coniopteris westwaterensis and Ilex serrata.
