Effects Of Low Ph On Lactate Dehydrogenase Kinetics Of Diving And Nondiving Reptiles, Dennis A. Baeyens, Salim R. Hurley
Effects Of Low Ph On Lactate Dehydrogenase Kinetics Of Diving And Nondiving Reptiles, Dennis A. Baeyens, Salim R. Hurley
Journal of the Arkansas Academy of Science
The properties of lactate dehydrogenase were examined in two snake species, Nerodia rhombifera and Elaphe obsoleta, and a turtle species, Pseudemys scripta. Our purpose was to compare the LDH activity of reptiles with limited anaerobic capabilities with that of the well established diver Pseudemys. The Michaelis-Menten kinetics of LDH and its susceptibility to inhibition by elevated pyruvate concentrations were investigated in the brain and heart of the three species. All tissue incubations and enzyme activity determinations were done at a pH of 7.0 in order to stimulate a diving blood pH in the three species. In both tissues the LDH …

Plasma Corticosterone Levels In Cholesterol-Fed Cockerels Before And After A Twenty Minute Run, Stanley N. David, Clarene L. David
Plasma Corticosterone Levels In Cholesterol-Fed Cockerels Before And After A Twenty Minute Run, Stanley N. David, Clarene L. David
Journal of the Arkansas Academy of Science
Cockerels were exercised to observe the influence of physical activity on plasma corticosterone concentrations. The birds were maintained on a commercial mash or on an atherogenic diet. Plasmas were collected on the first day, fifteen days after the first collection and immediately after a 20 minute run on that fifteenth day. The plasma corticosterone levels as determined by radioimmunoassay showed extreme variations within collections. Hence, the data analysis indicated no significant changes of the Compound β in the blood of the cockerels due to diet, or exercise or the combination of both. The causes for the wide variation of plasma …
Tagging And Marking Crawfish (Procambarus Clarkii) In A Population Estimation Study, Frank Meriweather
Tagging And Marking Crawfish (Procambarus Clarkii) In A Population Estimation Study, Frank Meriweather
Journal of the Arkansas Academy of Science
Crawfish (Procambarus clarkii) were tagged with enumerated plastic streamers and released in 0.1-ha ponds to observe recapture frequency in stand-up traps. Also, crawfish were marked by a uropod punch, released and recaptured in 0.1-ha ponds for population estimation. Survival of streamer-tagged crawfish in indoor tanks averaged 46.7% after 25 days, indicating that tagging caused stress leading to mortality, especially during molt. Recapture frequencies of tagged crawfish indicated sampling bias which obviated use of the tagging method in population assessments. Short term (3-day) survival of marked crawfish (92%) and retention of the mark after molt indicated potential application in population assessment …

Effects Of Juglone (5'-Hydroxy-1, 4-Naphthoquinone) On The Algae Anabaena Flos-Aquae, Nostoc Commune, And Scenedesmus Acuminatus, V. Diane Randall, Jimmy D. Bragg
Journal of the Arkansas Academy of Science
Three species of algae, Anabaena flos-aquae, Nostoc commune and Scenedesmus acuminatus were selected for their sensitivity to juglone and studied for the effects of juglone concentrations of 10, 1, 0.5, 0.1 and 0.01 μg/ml upon their growth. A. flos-aquae was most sensitive, with significant inhibition by the 0.5 μg/ml concentration. N. commune was inhibited least, with significant inhibition only in the 10 μg/ml concentration. S. acuminatus was found to be moderately inhibited at the 0.5 μg/ml concentration. All species were found to be non-viable after 14 days exposure to 10 μg/ml juglone. Tests with 7 and 14 day old cells …
Optimal Conditions For Kinetic Study Of Succinate Dehydrogenase In Rat Liver, Collie B. Shaw, Tara L. Chronister, John D. Peck
Optimal Conditions For Kinetic Study Of Succinate Dehydrogenase In Rat Liver, Collie B. Shaw, Tara L. Chronister, John D. Peck
Journal of the Arkansas Academy of Science
Succinate dehydrogenase (SDH) commonly is assayed as a marker enzyme for mitochondrial activity. The literature presents numerous conditions for conducting this assay due to the fact that, it has been difficult to get sufficient reduction of the acceptor dye, 2,3,5-triphenyl-2H-tetrazolium chloride (TTC). This study was undertaken to optimize the SDH-catalyzed reduction of TTC dye by evaluation of a greater range of molor ratios of TTC to succinate and by further evaluation of additives reported as beneficial. Improvement in enzyme specific activity was achieved by liver perfusion via the left cardiac ventricle with homogenizing solution. Increase in TTC from 1 to …

Effects Of Temperature And Crowding On The Pathogenicity Of Edwardsiella Ictaluri In Channel Catfish (Ictalurus Punctatus), Sharon L. Johnson, Lawrence W. Hinck
Journal of the Arkansas Academy of Science
Channel catfish were injected with Edwardsiella ictaluri and stocked at increasing temperatures and densities. Bacteriological examination of kidney, liver and spleen revealed the greatest numbers of organisms in fish from the highest temperature and stocking density tested. Survival time was the shortest for fish held at the highest temperature and stocking density. Increased temperature and crowding were directly proportional to the number of organisms recovered from the organs and inversely proportional to fish survival time.

Analysis Of Arkansas Fur Harvest Records - 1942-1984: Iii. Harvest-Price Relationships, Joseph D. Clark, Gary A. Heidt, Tina Sheldon, James H. Peck
Journal of the Arkansas Academy of Science
Correlation and linear regression analyses between mean annual pelt price and total harvest of 13 Arkansas furbearer species between 1965 and 1983 were performed for state and regions (Ozark Mountains, Ouachita Mountains, Gulf Coastal Plain, and Mississippi Delta). Statewide, strong correlations (r > 0.80) were identified for bobcat (Felis rufus), coyote (Canis latrans), gray fox (Urocyon cinereoargenteus), mink (Mustela vison), nutria (Myocastor coypus), opossum (Didelphis virginiana), and raccoon (Procyonlotor). Moderate correlations (r = 0.55 - 0.79) were identified for eastern spotted skunk (Spilogale putorius), muskrat (Ondatra zibethicus), river otter (Lutra canadensis), and striped skunk (Mephitis mephitis). Nonsignificant correlations (r < 0.468) were shown for beaver (Castor canadensis) and long-tailed weasel (Mustela frenata). Regional differences were noted for each species.
