The Rate Of The Healing Process In Venous Thrombi Produced By A Sclerosing Agent With Special Attention To Endothelial Lining, Kiyoshi Tanaka

Loma Linda University Electronic Theses, Dissertations & Projects

Despite extensive clinical and experimental investigations of venous thrombosis, relatively little is known about the early phases of healing of the venous thrombus. Soon after its discovery heparin has become the most popular agent for the prevention and treatment of venous thrombosis, but there are a number of unanswered questions regarding the most satisfactory treatment for venous thrombosis.

One area of controversy has been the duration of anticoagulation therapy for acute venous thrombosis. If the anticoagulant is discontinued too soon, the thrombus may continue to propagate. Prolonged anticoagulant therapy exposes the patient to the risk of serious hemorrhage. The objective …

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 …

Role Of Cytochrome P-450 In Methemoglobin Formation By Primaquine With Hamster Liver Microsomes, Tommy L. Hicks

Loma Linda University Electronic Theses, Dissertations & Projects

The role of cytochrome P-450 in in vitro methemoglobin formation by primaquine was investigated through a series of experiments with golden-Syrian hamsters, treated before sacrificing with phenobarbital or 20-methylcholanthrene to increase the cytochrome P-450 content or with cobaltous chloride to cause its decrease. To determine the extent of induction in the liver microsomal cytochrome P-450-dependent mixed-function oxidases, cytochrome P-450 content and formaldehyde from the 0-demethylation of p-nitroanisole were measured. A 90% increase occurred in cytochrome P-450 content with phenobarbital pretreatment and an increase of 102% was observed in p-nitroanisole 0-demethylation. Formaldehyde from primaquine increased 64%. The methylcholanthrene treatment produced a …

Patterns Of Fatty Acid Release From Endogenous Substrates By Human Platelet Homogenates And Membranes, A Derksen, P Cohen

Faculty, Staff and Students Publications

We describe a method for measuring the release of fatty acids from endogenous substrates of human platelet homogenates and membranes. The method depends on the availability of lipids whose fatty acids are odd-chained and therefore suitable as internal reference compounds that, at the time of lipid extraction, can be added to an incubation to permit subsequent quantification of the content of free fatty acids or fatty acids esterified to specific lipids. We found four types of lipolytic activities in human platelets. In homogenates at pH 4.0 a triglyceride lipase operated as shown by the synchrony of triglyceride degradation and release …

The Relationship Of Alcohol Consumption In Rats To Morphine And Codeine Intake And The Metabolism Of Dopamine, Hsiu Fen Liu

Loma Linda University Electronic Theses, Dissertations & Projects

The effects of morphine and codeine free-choice alcohol consumption in male Sprague-Dawley rats were studied. Intakes of a 10% alcohol solution in milliliters per 100 gm. of body weight were on recorded weekly. No difference was found in the alcohol intake of rats given either a morphine-supplemented diet (0.01% of the diet) or daily injection of morphine sulfate (2 mg./kg.); however, there was a significant lower intake of water (p < .05) in those rats fed the diet with morphine. Total fluid consumption of both groups given the morphine-supplemented diet and daily injection of morphine sulfate was decreased (p < .05). It was found that morphine did not affect the percentage of total fluid consumed as alcohol or the weight gain.

Two levels of codeine phosphate (10 mg./kg. and 20 mg./kg.) were injected subcutaneously into rats twice a day. It was observed that the codeine significantly decreased alcohol intake in rats …

The Effect Of Glucose On The Food Intake Of Goldthioglucose Injected Mice, Janet Lahti

Dissertations and Theses

Jean Mayer has postulated the presence of glucoreceptors located primarily in the ventromedial hypothalamic nuclei of the brain which are activated by glucose in the measure that they utilize it. According to Mayer, hunger occurs when glucose is not available for metabolic purposes and satiation supervenes when glucose is made available. Control of this mechanism rests with the glucoreceptors. These receptors are believed to be destroyed when an injection of the compound goldthioglucose is given to mice. These animals subsequently become obese and are found to have gold deposits and lesions in the ventromedial area and also in other parts …

Mathematical Model Of Placental Oxygen And Carbon Dioxide Exchange, Ester P. Hill

Loma Linda University Electronic Theses, Dissertations & Projects

This model of placental CO₂ and O₂ exchange calculates the time course of changes in P_^CO2, [HCO₃^-], and [H⁺] in each of four "compartments" of placental exchange vessels: maternal erythrocytes, maternal plasma, fetal plasma and fetal erythrocytes. The changes in hemoglobin-bound CO₂ (carbamate) and oxyhemoglobin contents within the erythrocytes are also calculated, permitting consideration of the Haldane and Bohr effects. Equations were written to represent one-dimensional steady state CO₂ and O₂ diffusion between concurrent maternal and fetal capillaries and the subsequent hydration, carbamino and oxyhemoglobin reactions. The equations …

Effect Of Lateral Positioning On Central Venous Pressure, Romelda C. Jereos

Loma Linda University Electronic Theses, Dissertations & Projects

This experimental study was conducted to investigate the effects of lateral positioning on central venous pressure. It was hypothesized that lateral positioning would not significantly change the central venous pressure so long as the subjects were placed on the same horizontal plane for both supine and lateral measurements. It was also hypothesized that the length of time spent in the lateral position would not alter the pressure.

It is recognized that several factors do indeed play important roles in the maintenance of central venous pressure. The effect of one particular influencing factor, gravity, was central to this study. The difference …
