Delayed Onset Of Muscle Soreness: Creatine Kinase As A Marker For Tissue Damage (Pgf(2a) Metabolite)., John Douglas Boatwright Jan 1986

Delayed Onset Of Muscle Soreness: Creatine Kinase As A Marker For Tissue Damage (Pgf(2a) Metabolite)., John Douglas Boatwright

LSU Historical Dissertations and Theses

Twenty college age males participated in a weight-lifting experiment, 3 sets of 10 repetitions at 70% 1RM for the squat, to examine the time courses between creatine phosphokinase (CPK), prostaglandin F(,2) alpha metabolite (PGF(,2a) met) and ratings of perceived soreness (RPS). Both groups, aspirin (n = 10) and placebo (n = 10), received medication (3g/day) for four consecutive days, starting 1 day prior to workout. Ratings of soreness and blood samples were taken pre- and immediately post-exercise, and at 24 h intervals for 3 days after exercise. There was no significant difference (p < 0.05) between the groups for CPK and RPS across time, but the prostaglandins were significantly different (p < 0.01) at all time intervals between groups. Changes seen across time were quadratic for all variables. The 24 h prostaglandin level was significantly higher (p < 0.05) than the pre-, post-exercise and 72 h levels, but not significantly different from the 48 h level. Ratings of soreness were not significantly different (p < 0.05) at the 24 and 48 h intervals, but both were significantly higher than at all other time intervals. The mean CPK levels at 24 and 48 h were not significantly different (p < 0.05), but the 24 h CPK level was significantly higher (p < 0.05) from the other time intervals. There was a significant correlation (p < 0.01) between the time courses of CPK and RPS. It was concluded that CPK can be used as a marker for tissue damage and that prostaglandins did not influence the subjects' perception of muscle soreness or the release or uptake of CPK.

Facilitative And Inhibitory Interactions Among Estuarine Meiobenthic Harpacticoid Copepods (Commensalism, Benthos, Louisiana)., George Thomas Chandler Ii Jan 1986

Facilitative And Inhibitory Interactions Among Estuarine Meiobenthic Harpacticoid Copepods (Commensalism, Benthos, Louisiana)., George Thomas Chandler Ii

LSU Historical Dissertations and Theses

In Louisiana, USA, marshes, the harpacticoid copepods Scottolana canadensis and Pseudostenhelia wellsi are community co-dominants with similar lifestyles. Scottolana canadensis is a semi-sessile burrow-dweller capable of subsurface suspension and deposit feeding. Pseudostenhelia wellsi is a semi-sessile tube-building copepod that continuously corkscrews back and forth within its tube and appears to graze on the inner tube walls. Monospecific patches of both species (250 (.) 5cm('-2)) were generated in laboratory microcosms to determine their effects on colonization by two completely errant, burrowing harpacticoids, Nitocra lacustris and Cletocamptus deitersi, that have similar foraging and burrowing behaviors and similar effects on sediment structure. Pseudostenhelia …

Effect Of Experimental Ostertagia Ostertagi Infection Or Chronic Pentagastrin Treatment On Abomasal Pathophysiology And Morphology Of Goats., Judit Eva Markovits

LSU Historical Dissertations and Theses

European-type mixed-breed goat kids were infected with Ostertagia ostertagi or were given chronic pentagastrin treatment. Selected clinicopathological parameters and fecal egg counts were monitored throughout the study. At necropsy the abomasal physical parameters were recorded and tissue samples were saved for parasite recovery, quantitative and qualitative light microscopy and transmission and scanning electron microscopy. Serum pepsinogen and gastrin immunoreactivity increased in parasitized animals. The increase was associated with the tissue phase of the parasitic development. Pentagastrin did not alter pepsinogen or gastrin immunoreactivity. All 8 infected animals had patent infection, and approximately 5% establishment of the infective dose of 15,000 …

Stories And Storytelling In The "Libro De Buen Amor": Juan Ruiz's Use Of Folktales To Admonish, Persuade And Deceive (Spain)., Cynthia Powell Jayne Jan 1986

Stories And Storytelling In The "Libro De Buen Amor": Juan Ruiz's Use Of Folktales To Admonish, Persuade And Deceive (Spain)., Cynthia Powell Jayne

LSU Historical Dissertations and Theses

The Libro de buen amor, a fourteenth century Spanish text by Juan Ruiz, is an extensive and complex poem rich in partially hidden messages. Thirty-five popular medieval tales form an integral part of the body of the work, and convey important information to the reader through the text of the tales and through the storytelling context created by the author. Scholars have studied the tales most often from an historical perspective, and analyzed them separately from the central narrative; or have studied the textual materials with little emphasis on the function of the tales. Although such studies provide valuable information, …

The Image Of Walking In Hawthorne's Fiction (Journey Motif, Pilgrimage)., Frances Murphy Zauhar Jan 1986

The Image Of Walking In Hawthorne's Fiction (Journey Motif, Pilgrimage)., Frances Murphy Zauhar

LSU Historical Dissertations and Theses

Various scholars have referred to the metaphorical journey in Hawthorne's work. This is the first comprehensive study of the journey image in Hawthorne's fiction. Inquiring into the relationship between the imagery in Hawthorne's short stories and his longer fiction, the study examines the sources of Hawthorne's fascination with the journey motif. Hawthorne uses the journey in his first published work, Fanshawe. Both contrived and derivative of his reading of travel literature and fiction, especially The Pilgrim's Progress, Fanshawe exhibits all facets of the journey-related imagery that Hawthorne employs in his later fiction. Hawthorne wrote his short stories after he wrote …

Characterization Of The Protein And Glycoprotein Components From Antigenically Distinct Strains Of Equine Infectious Anemia Virus., Olivia Salinovich Jan 1986

Characterization Of The Protein And Glycoprotein Components From Antigenically Distinct Strains Of Equine Infectious Anemia Virus., Olivia Salinovich

LSU Historical Dissertations and Theses

Four isolates of equine infectious anemia virus (EIAV) recovered weeks apart from a single experimentally infected Shetland pony (Orrego, 1983) were examined in both antigenic and structural analyses to investigate variation occurring during persistent infection. These four isolates were shown to be antigenically distinct in both serum neutralization assays and in immunoblot analysis with either a polyclonal equine reference antiserum or a panel of virus-specific monoclonal antibodies. Two-dimensional mapping of tryptic peptides of viral components from these isolates revealed that both gp90 and gp45 undergo structural variation during virus replication in a single animal, but that no such structural variation …

Molecular Studies Of T-Lymphocytes From Bovine Leukemia Virus-Infected Cattle., Diana Lynn Williams

LSU Historical Dissertations and Theses

Highly specific monoclonal antibodies and microfluorimetry were used to determine the absolute number of B and T lymphocytes in the peripheral blood of bovine leukemia virus (BLV) infected cattle. The peripheral blood lymphocyte populations from BLV-infected cattle were elevated when compared to BLV-negative animals. The increase in the lymphocyte population in the aleukemic (AL) animals was due to an increase in T lymphocytes. In the PL animals the increase was due mainly to an increase of B lymphocytes but also to an increase of T lymphocytes. The PL animals showed a significantly higher number of surface immunoglobulin positive cells (sIg('+)) …

Characterization Of Messenger Ribonucleoprotein Particles In Dormant Sporangiospores Of The Fungus Mucor Racemosus (Messenger-Rna)., Charles Patrick Chapman Jan 1986

Characterization Of Messenger Ribonucleoprotein Particles In Dormant Sporangiospores Of The Fungus Mucor Racemosus (Messenger-Rna)., Charles Patrick Chapman

LSU Historical Dissertations and Theses

Extracts of sporangiospores of Mucor racemosus contained RNA that readily hybridized with ('3)H polyuridylic acid. Prior to germination, this RNA was in a form sedimenting at <80S. Within 10 minutes after initiating germination, most of this RNA sedimented with polyribosomes and 80S monoribosomes. Particulate material from spore extracts bound to oligo dT -cellulose at high ionic strength and was assumed to contain messenger ribonucleoprotein particles (mRNP's). A portion of the mRNP's was released from the column by lowering the ionic strength. Other portions were eluted stepwise in buffer containing 50% and 90% formamide and in 0.1-N NaOH. Identical elution patterns were observed whether monitoring incorporated ('31)P-orthophosphate or L- ('32)S methionine, absorbance at 280 nm, or hybridization of ('3)H polyuridylic acid. mRNP's from the first two fractions were analyzed. A bimodal population of particles was detected in sedimentation velocity and sedimentation equilibrium centrifugation. Particles eluted at low ionic strength demonstrated a sedimentation coefficient distribution of 20S-to-80S, with a mean of 55S. Particles eluted in formamide demonstrated a sedimentation coefficient distribution of 20S-to-60S, with a mean of 40S. Particles eluted at low ionic strength displayed two peaks in CsCl centrifugation, with bouyant densities of 1.37 gm/cc and 1.59 gm/cc. Particles eluted in formamide displayed a single peak with a buoyant density of 1.61 gm/cc. Particles eluted at low ionic strength and centrifuged in metrizamide solution formed two bands having bouyant densities of 1.15 gm/cc and 1.30 gm/cc; formamide-eluted particles banded only at the higher density. Mucor 40S ribosomal subunits banded at 1.56 gm/cc and 1.28 gm/cc in CsCl and metrizamide solution respectively. Analysis of mRNP fractions by sodium dodecylsulfate-polyacrylamide gel electrophoresis characterized protein components of these particles which helped explain their biomodal sedimentation behaviour. Each mRNP fraction contained a unique spectrum of proteins not shared by ribosomes or soluble cell proteins. The formamide-eluted particles contained two proteins, whereas the particles eluted at low ionic strength possessed 12 proteins. A 24,000-dalton protein was the predominant form in both. The denser mRNP's were smaller and lacked proteins found in the larger less dense particles. The former had a protein/RNA ratio of 45/55; whereas the later possessed a value of 90/10. Messenger RNA extracted from the mRNP's sedimented between 8S-to-20S.
