Fetal Alcohol Effects: A Review Of The Current Literature And A Proposed Study Of The Possible Additive Effects Of Marihuana And Alcohol On The Fetus, Shirley Lange Kamp
Fetal Alcohol Effects: A Review Of The Current Literature And A Proposed Study Of The Possible Additive Effects Of Marihuana And Alcohol On The Fetus, Shirley Lange Kamp
Masters Theses
The purpose of this paper was to review the current state of knowledge regarding the effects of alcohol ingestion during pregnancy, to determine the specific issues that remain under speculation, and to develop a theoretical research design which might aid in determining the role, if any, of marihuana in compounding fetal alcohol effects.
The literature reviewed indicated that alcohol creates a continuum of fetal effects from mild abnormalities to the full fetal alcohol syndrome; current marihuana studies suggest possible adverse effects on the fetus. The research model was based on this evidence, the well documented usage of both drugs by …
Inhibition Of Synaptosomal Biogenic Amine Transport By A Diverse Group Of Neurotoxic Chemicals, William M. Bracken
Inhibition Of Synaptosomal Biogenic Amine Transport By A Diverse Group Of Neurotoxic Chemicals, William M. Bracken
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Synaptosomal membrane functions were monitored, after in vitro exposure to select environmental pollutants, in synaptosomal preparations originating from rat cerebral cortices. The uptake of NE and 5HT into the synaptosomes was monitored as was the K+-dependent phosphate activity of the membrane. CH3HgCl, Hg(NO3)2, CdCl2, diisopropylfluorophosphate (DFP), paraoxon, acrylamide and Kepone were the test chemicals whose effects were studied.
CH3HgCl, Hg(NO3)2 and Kepone had the greatest inhibitory effects on NE and 5HT uptake. The concentrations producing 50 percent inhibition (IC50) were 1.4 x 10 …
Leptophos Metabolism In The Rat: An In Vivo Study Of Oxidative Versus Conjugative Modes Of Metabolism, David Richard Hampson
Leptophos Metabolism In The Rat: An In Vivo Study Of Oxidative Versus Conjugative Modes Of Metabolism, David Richard Hampson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The objectives of this research were to examine the metabolism in vivo of the pesticide leptophos in the rat under normal conditions and during inhibition of the mixed-function oxidases and during depletion of glutathione. Glutathione is a cofactor in the conjugation reactions of the glutathione-S-transferases. Both the mixed-function oxidase system and the glutathione-S-transferases have been shown to be important in the biotransformation of other organophosphate pesticides.
Urinary metabolites of leptophos were extracted, derivatized and subsequently analyzed by gas-liquid chromatography. The methods used to analyze for alkyl phosphonates were subject to several shortcomings and modifications of the original procedure were necessary. …
A Computer Simulation Study Of Blood Cholinesterase Inhibition In Parathion Treated Rats, Scott Christopher Hennes
A Computer Simulation Study Of Blood Cholinesterase Inhibition In Parathion Treated Rats, Scott Christopher Hennes
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A computer simulation model of blood cholinesterase inhibition in rats resulting from a single oral or dermal dose of parathion was developed and tested. The model consists of a set of non-linear differential equations describing the absorption, distribution and metabolism of parathion and the kinetics of inhibition and reactivation of erythrocyte and plasma cholinesterase. The equations are numerically integrated to produce the time-course of each of the cholinesterase activities of the blood. The model was tested for validity by a comparison of the activities predicted by the model to values determined experimentally in male rats. The model successfully simulated plasma …
The Effects Of Tri-O-Tolyl Phosphate (Totp) On The Immune System Of Mice, Craig R. Brinkerhoff
The Effects Of Tri-O-Tolyl Phosphate (Totp) On The Immune System Of Mice, Craig R. Brinkerhoff
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
TOTP is a prevalent industrial and environmental contaminant which has been shown to be a neurotoxic agent. This study was undertaken to investigate the effects of this compound on the immune system. Several techniques were employed to test the humoral as well as cellular effects. Male Swiss Webster mice were administered by gastric gavage with three doses of TOTP (5, 50, and 500 mg/kg) and one dose TMTP (50 mg/kg) in corn oil once a week for 13 weeks. Control animals were given corn oil alone.
Lymphocyte transformation was determined on cultures of splenic cells obtained from animals sacrificed at …
Pesticide Exposure Studies: Direct And Indirect Detection Of Absorption Of 2,4-D And Pronamide Herbicides In The Guinea Pig And Occupationally Exposed Workers, Ibrahim A.R. Al-Jabery
Pesticide Exposure Studies: Direct And Indirect Detection Of Absorption Of 2,4-D And Pronamide Herbicides In The Guinea Pig And Occupationally Exposed Workers, Ibrahim A.R. Al-Jabery
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
A simple high pressure liquid chromatography procedure was used to determine 2,4-D and pronamide exposure in spraymen and their dermal absorption and excretion in guinea pigs.
Results of dermal application of these herbicides to guinea pigs demonstrated a strong correlation between the applied dermal dose and the urinary residue excretion over the dosage range tested. As the dosage was increased, the urinary excretion of residues was also increased. However, the excretion of 2,4-D amine mixture following dermal treatment of guinea pigs was prolonged as compared to that of pronamide.
Residue levels of these compounds were also determined to estimate skin …
Accumulation Of Formaldehyde And Its Relation To Postmortem Aging Of Non-Gadoid Fish Species, Mohamad A. Al-Kanhal
Accumulation Of Formaldehyde And Its Relation To Postmortem Aging Of Non-Gadoid Fish Species, Mohamad A. Al-Kanhal
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Three non-gadoid fish species, trout (Cynoscion regalis), English sole (Paraophyrys vetulus) and Pacific red snapper (Scomber japonicus) have been tested for the recovery of trimethylamine oxide (TMAO), trimethylamine (TMA), dimethylamine (DMA), and formaldehyde (FA) during postmortem storage at 4°C and -5°C. TMAO, TMA, and DMA content was determined by measuring them as the salt derivative of picric acid. FA was determined by using the 3-Methyl-2-Benzothiazolinone hydrazone test.
In muscle tissue of red snapper and English sole, it was clear that initially TMAO decreased during storage at 4°C, while the amounts of TMA, DMA, and …
Sulfatides As Opiate Receptors: An Evaluation Of The Opiate Binding Potential Of Sulfogalactosylgylcerolipid, Darby Geoghegan Hand
Sulfatides As Opiate Receptors: An Evaluation Of The Opiate Binding Potential Of Sulfogalactosylgylcerolipid, Darby Geoghegan Hand
Chemistry & Biochemistry Theses & Dissertations
Cerebroside sulfate (CS) has recently been shown to bind opiate drugs in a pharmacologically relevent manner and therefore satisfy the structural requirements of an opiate receptor. Seminolipid (SGG), a novel sulfated galactosyl. glycerolipid that has been isolated from the testes of a variety of mammals, may be viewed as a structural analog of CS. In view of this structural similarity, it is reasonable to presume that SGG may also bind opiate drugs. The isolation of SGG from boar testes was accomplished using silica gel dry column chromotography with a chloroform: methanol water solvent system. The structure and purity of the …

Effects Of Organic Compounds On Amphibian Reproduction, Wesley J. Birge, Jeffrey A. Black, Robert A. Kuehne
Effects Of Organic Compounds On Amphibian Reproduction, Wesley J. Birge, Jeffrey A. Black, Robert A. Kuehne
KWRRI Research Reports
Aquatic toxicity tests were conducted with atrazine, carbon tetrachloride, chloroform, methylene chloride, trisodium nitrilotriacetic acid (NTA), and phenol. Each compound was administered to developmental stages of three to five amphibian species. Exposure was initiated at fertilization and maintained through 4 days posthatching. Test responses included lethality and teratogenesis. Different amphibian species exhibited varying degrees of tolerance to the selected compounds. Greatest tolerance usually was observed for the more broadly adapted semi-aquatic and terrestrial species (e.g., Bufo americanus, Bufo fowleri). The more sensitive amphibians usually included those species which normally are restricted to aquatic or moist habitats (e.g., Rana …

Psychopharmacological Analysis Of Central Muscarinic And Nicotinic Receptors, Leonard T. Meltzer
Psychopharmacological Analysis Of Central Muscarinic And Nicotinic Receptors, Leonard T. Meltzer
Theses and Dissertations
Arecoline and nicotine are two psychoactive cholinergic alkaloids. Arecoline is primarily a muscarinic agonist while nicotine, at low doses, is a nicotinic agonist. The experiments in this dissertation investigated two major areas: (1) the role of different factors in the development of tolerance to the behavioral effects of arecoline and nicotine, and (2) the possible mechanism and site of action of the discriminative stimulus (DS) effects of arecoline and nicotine.
The role of dispositional and physiological factors comfiared to behavioral factors in the development of tolerance to the effects of arecoline and nicotine on operant behavior was assessed in Experiments …
Estimate Of The Total Weight Of Kepone In The Major Components Of The Molluscan Fauna Of The James River, Virginia, Dexter S. Haven, Reinaldo Morales-Alamo
Estimate Of The Total Weight Of Kepone In The Major Components Of The Molluscan Fauna Of The James River, Virginia, Dexter S. Haven, Reinaldo Morales-Alamo
Reports
Contamination of the James River in Virgin ia with the pesticide Kepone has resulted in its accumulation in the tissues of the fauna inhabiting the river. Most of the Kepone available to the biota in the river is associated with sediment s (Schneider and Dawson, 1978) and Haven and Morales-Alamo (1979) have shown that oysters and other bivalve molluscs accumulate Kepone in their tissues when exposed to the pesticide associated with sediments in suspension. It is of interest to compare the quantities of Kepone bound in James River sediments with the quantities bound in the molluscan fauna of the river.
