Age-Changes Of The Neuronal Component Of Meissner Corpuscles In The Mouse Digital Pad, Roger C. Mathewson

Loma Linda University Electronic Theses, Dissertations & Projects

Silver impregnated sections of mouse digital pads were studied using light microscopy to detect age-related changes of the neuronal component of Meissner corpuscles. Direct microscopic observation, photomicrographs and camera lucida tracing were utilized. From qualitative observation, the corpuscular neurites were found to undergo morphological age-related changes of diameter, tortuosity, varicosity, branching and terminal expansion size. Quantitative examination was made of the number of corpuscles, corpuscular neurites, branching neurites, cross-innervations, terminal neurite expansions, neurite intraepidermal continuations and terminal axonal processes. The number of corpuscles and neurite intraepidermal continuations decreased with age while having significant linear correlation; whereas, branching increased with age …

Patterns Of Fetal Lamb Regional Cerebral Blood Flow During And After Prolonged Hypoxia, Stephen Ashwal, John S. Majcher, Nestor Vain, Lawrence D. Longo

Loma Linda University Electronic Theses, Dissertations & Projects

[Abstract not included]

Speculation: In the fetal lamb during prolonged intrauterine hypoxia, total and regional cerebral blood flows increase to the same extent without evidence of preferential shunting to critical brainstem or subcortical areas. Neuropathologic studies have indicated relative sparing of these areas during similar animal experimental or human neonatal conditions. This suggests that the pattern of hypoxic ischemic insult to the neonatal central nervous system associated with asphyxia may differ from that produced by hypoxia alone. In addition, during asphyxia these pathologic changes may result primarily from hypotension and decreased regional cerebral blood flow, or from regional metabolic derangements …

A Comparison Of Ecs And Drug Induced State-Dependent Learning, Mayse F. John

All Master's Theses

The purpose of the present experiment is twofold: (a) to determine if FS and ECS or just ECS can be used as an agent to produce "dissociated" learning in a multi-trial procedure, and (b) if shown, to determine the effectiveness of these agents relative to three different dosages of sodium pentobarbital preselected to produce no, moderate, and complete dissociation.

Chemical Poisoning In Animals. 2. Lead, H D. Seddon

Journal of the Department of Agriculture, Western Australia, Series 4

LEAD is the most frequent cause of poisoning in farm animals, especially of cattle.

All animals and man are susceptible to large doses, but small repeated doses may accumulate to toxic proportions in the body.

Cattle and sheep are more susceptible to poisoning and are more likely to have access to sources of lead.
