Stroke is one of the leading causes of deaths as the risk factors, both controllable and uncontrollable, are many. We first concentrated on a stress-free way to deliver the drugs. Our preference was to have the animals ingest the drugs, which led us to a reliable method for orally administering medication to the animal models. Using three different drug combinations, we tested the effects on neurogenesis without stroke. We found the drug combination of Fluoxetine/Statin/Ascorbic acid increases neurogenesis 19 fold when compared with control. Lastly, we looked at the gene changes in the cortex of the animal models that had …

The carotid bodies (CB), the primary peripheral chemoreceptors, respond to changes in blood gases with neurotransmitter release, thereby increasing carotid sinus nerve firing frequency and ultimately correcting the pattern of breathing. It has previously been demonstrated that acute application of the adipokine leptin caused perturbations of intracellular calcium and membrane ion movement in isolated CB Type I cells (Pye et al, 2015) and augmented the response of the intact CB to hypoxia (Pye et al, 2016). This study's aim was to examine, in-vivo, if elevated leptin modulated CB function and breathing. Rats were fed high-fat chow or control chow for …

Ischemic strokes account for 87% of all strokes and can have debilitating effects on language, sensory, and motor skills. Currently, tPA is the only medication approved by the FDA for the treatment of ischemic stroke, but the window of time to administer the drug is very small. In this thesis, we investigate the use of a simvastatin and fluoxetine drug combination (FS) as a possible treatment for ischemic stroke victims. To analyze the effects of FS on neurogenesis and functional recovery, we utilize the Montoya Staircase and quantify the amount of neurogenesis using doublecortin. Although the results of this study …

In this study, we hypothesize that a pharmacological drug treatment comprised of Fluoxetine, Simvastatin and Ascorbic acid together with physical rehabilitation would reduce infarct sizes. Over the period of 60 days after stroke-induction, 13 of the 23 rats were administered the drugs beginning 20-26 hours after stroke-induction and the rest were assigned to the control group. Physical rehabilitation exercises were initiated from poststroke day 8 and continued for 23 alternate days. The rats were tested for functional recovery using Montoya staircase apparatus and were euthanized after post-stroke day 60. The brains sections were analyzed using Nissl stain for infarct volume …

In the present study 10-12 month female rats were examined for functional recovery from stroke and this recovery was compared with the stem cell/progenitor cell proliferation in the brain (which was measured by Ki67). The cell proliferation indicated by Ki67 showed a 6 fold increase in control animals compared to the rehabilitation animals. The contralateral functional recovery in control animals were 46.6% and in the rehabilitation animals were 24.5%. The physical rehabilitation was carried out to determine if limb rehabilitation can promote greater functional recovery. The results showed that when the animals were made to over use their impaired limb …

Until now, observations regarding the central morphology and organization of Ia, group II and Ib Golgi tendon organ afferents have been confined to the cat model. As the use of rodents in the study of the development and organization of segmental spinal cord circuitry increases, a complete account of the peripheral encoding and central connectivity of rodent muscle proprioceptors is necessary. The data presented in this study establish the central morphology and spatial distribution of 12 (4 of each class) functionally phenotyped muscle proprioceptor afferents in the rat by intracellular labeling with Neurobiotin. Each afferent type showed a characteristic central …

In Carbon Monoxide (CO) induced Delayed Neurological Sequelae (DNS) clinical signs develop 1 to 6 weeks after CO has cleared the body. The aim of this experiment was to develop a model of CO induced DNS which closely mimics "real world" conditions both in exposure and treatment. The model was challenged with hyperbaric or normobaric oxygen, or room air. Basic behaviors were measured by Open Field test on days 1, 7, 14 post exposure and treatment. No significant difference in behavior was observed between exposed and control animals or between treatment groups. Histological analyses showed no DNA or necrotic damage …

Contact dermatitis is one of the most common occupational diseases. Absenteeism of the affected workers and associated health care costs makes this disease an economically important issue. Irritant contact dermatitis (ICD) is a common contact dermatitis observed among workers. As each category of irritants triggers the inflammatory process by different method, studying the mechanism of ICD is difficult. Information on the mechanism of action of an irritant is indispensable for the development of effective prophylactic and therapeutic measures. In this study, we have investigated the early changes in rat skin induced by jet fuel-8 (JP-8). Although previous studies have described …
