The vagal inhibitory reflex in the rat stomach

Creator:: Lock, Albert
Abstract:: Electrical stimulation of the vagus nerves produces an excitatory contraction response in the isolated rat stomach. This contraction response was abolished by atropine to unmask the vagal inhibitory response (VIR) elicited during low frequency vagal stimulation. Babring and Gershon (1967), after working on guinea-pigs and mice, hypothesized that both serotonin...

The use of resonant transfer for combined switching and multiplexing

Creator:: Getgen, Lawrence E.
Abstract:: This paper presents a study of the resonant transfer of energy between filters with the viewpoint of applying this technique to communication systems. A summary of the existing filter designs for this application is made. This summary shows that a requirement common to all these filters is that the impulse...

An evaluation in rainbow trout of biliary excretion of sulfobromophthalein and effects of biliary excretion on the toxicity of rotenone

Creator:: Schmidt, Dana C.
Abstract:: Biliary excretion has been of considerable interest in mammals but has not been extensively studied in fish. To understand the significance of biliary excretion in rainbow trout (Salmo gairdneri), two studies were conducted. The objective of the initial study was to evaluate the ability of rainbow trout to excrete a...

Calcium regulation and physiological function in animals exposed to lead

Creator:: Hoffman, Norbert Edward
Abstract:: Tissue distribution studies of calcium and lead in brain tissue of rats were increased subsequent to a single intravenous injection of lead, 10 mg/kg, in the form of lead acetate. Time-course studies demonstrated that brain concentrations of calcium and lead (in terms of wet tissue weight) were found to be...

Aspects of comparative neuromuscular physiology and pharmacology of black bass (Micropterus salmoides) as evidenced by the action of diisopropylfluorophosphate

Creator:: Schneider, Phillip William
Abstract:: Neuromuscular physiology has been extensively investigated in several groups of vertebrates excluding fish. To understand the nature of neuromuscular transmission in this group, the response of the pectoral fin abductor muscle of black bass (Micropterus salmoides) to nerve stimulation under the influence of an anticho1inesterase agent was studied. Diisopropylfluorophosphate (DFP),...

The relationship between environmental lighting and hydroxyindole-o-methyltransferase activity in the pineal gland of steelhead trout (Salmo gairdneri)

Creator:: Smith, John Robert
Abstract:: Pineal hydroxyindole-0-methyltransferase (HIOMT) activity was monitored over a 24 h period under three different photoperiods, 16L:8D, 8L: 16D, and 12 L:12D. It was observed that in all three groups of fish HIOMT activity was high' during the dark portion of the photoperiod in comparison to activity during the light portion....

The use of electromagnetic Walsh waves in radar

Creator:: Schaffer, Alvin
Abstract:: The question of the suitability of Walsh functions or similar bi-valued functions used as a radar electromagnetic carrier waveform is considered. Walsh functions are described and effective sinusoidal steady state transfer functions are defined for transmission elements, antenna systems, and propagation media. The argument is made that the unit impulse...

Changes in the swimming performance, behavior and physiology of juvenile chinook salmon (Oncorhynchus tshawytcha) after exposure to one, two or three acute handling stresses

Creator:: Sigismondi, Linda A.
Abstract:: The performance of an organism or organismic subsystem is the result of the interaction between the performance capacity of the system and Its environment. Environmental conditions can stress an organism and thus affect it's performance. In this study, three whole organism performances were examined: critical swimming speed, fatigue time and...

An assessment of the cardiac toxicity of compounds that cause methemoglobinemia using a non-vascularized fish heart model

Creator:: Nichols, John W.
Abstract:: Non-vascularized hearts of buffalo sculpin (Enophrys bison) were used to investigate the cardiac toxicity of compounds that cause methemoglobinemia. The affinity of sculpin cardiac myoglobin for oxygen (P50 = 1.10 torr at 20 C°, pH 7.8) was lower than that of mammals studied (P50 = .44 and .76 torr for...

Acetylcholine synthesis, storage, degredation and nicotinic receptores in a rat model for space-induced muscle atrophy

Creator:: Royland, Joyce E.
Abstract:: Space flight results in loss of mass and function in skeletal muscle. Data from manned flights and animal biosatellites give evidence of possible changes in neuromuscular interactions. Components at the neuromuscular junction are a potential site of action for this space-induced muscle atrophy. We examined the nicotinic acetylcholine receptor population...
