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...

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...

Pineal and retinal acetylserotonin methyl-transferase activity in trout

Creator:: Smith, John Robert
Abstract:: Pineal acetylserotonin methyltransferase (ASMT) activities in rainbow trout were reported on by Hafeez and Quay (1971). The validity of certain assay parameters used by these researchers were investigated. With the exception of incubation temperature, all parameters studied proved to be quite valid. Temperature studies indicated a low stability for trout...

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),...

A study of some physiological properties of ovine and bovine utero-ovarian arteries

Creator:: Kuhl, Lynda Marie
Abstract:: The utero-ovarian vasculature of domestic animals has been a popular research subject, especially concerning the roles of the uteroovarian artery and vein in the unilateral luteolytic phenomenon demonstrated in these animals. No reports in the literature, however, have been found regarding the smooth muscle physiology of these vessels. The present...

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....

Relative resistance of the Coho salmon (Oncorhynchus kisutch) and the Chinook salmon (Oncorhynchus tshawytscha) to the parasitic larvae (Glochidia) of the freshwater mussel (Margaritifera margaritifera)

Creator:: Fustish, Charles A.
Abstract:: The relative resistance of the coho salmon (Oncorhynchus kisutch) and the chinook salmon (O. tshawyscha) to the parasitic larvae (glochidia) of the freshwater mussel (Margaritifera margaritifera) was studied in an attempt to determine why the coho appeared to be more resistant. Natural and acquired antibody was sought in the mucus...

Sulfobromophthalein disposition in rainbow trout (Salmo gairdneri) as influenced by carbon tetrachloride intoxication

Creator:: Gingerich, William H.
Abstract:: Clinical methods to diagnose specific organ dysfunction have not been evaluated in fishes. To determine if an accepted clinical test of mammalian liver function could be applied to fishes, the hepatic disposition of the organic anion sulfobromophthalein (BSP) was studied in rainbow trout (Salmo gairdneri) treated with a model hepatotoxicant....
